@Dr Brad Stanfield is there any validity for claims that Resveratrol increases Nitric Oxide production, improves genetic health, protects brain from cell damage and makes blood fats healthier? I purchased Resveratrol from Eternum Labs and these claims are on the container with further claims for Resveratrol on the website. Thanks for speaking out!
remember, that even Doc Since. says - hey I am self experimenting on myself...There is a risk.. A lot of this stuff is theoretical! I think the disagreements are very important, to get to the truth! Colelctively - Berg, Ekberg, Stanfield, Sinclair.... all these channels are insanely good! They all could be related....even the names ..in a way...
this is why I subscribe to the Dr Stanfield channel. He has no fear reporting current studies bringing the largest of youTube whales or nutritional sacred cows into question... including his own past recommendations! He DOES let the facts "get in the way"; how admirable and edifying.
He's great. But I take him with a grain of salt. He is very bias towards "healthspan", so much so, that he compromises lifespan. He puts too much emphasis on consuming protein & muscle building, which is proven to promote ageing.
Although the ITP did consult with Sinclair, you didn't address the fact that they just gave the resveratrol to the mice in food without mixing it with fat. As Sinclair said, in their own studies giving it to the mice in regular food without fat didn't extend lifespan.
Surely David Sinclair should have volunteered such critical information to the ITP without being asked. After all he would have an invested interest in this trial showing life extention benefits under such conditions.
I have been taking Resveratrol since November 2021. My anxiety disappeared and I slept much better - that was he first thing I noticed. Then my energy levels increased - my body seemed to start craving exercise. I don’t think I am imagining any of this. I have noticed no side effects so far.
I experience profound benefits with Japanese Knotweed, but I understand that my case might be very specific. I don’t think this video necessarily implies that resveratrol as a compound has no therapeutic usage at all. For instance it appears that Japanese knotweed has some antimicrobial and immuno-modulating effects (whether that’s purely from resveratrol or from the combination of compounds I don’t know). Same as chemotherapy might be useful for some people.
I've been taking it for over a year now and I too thought that I have been improving. I think somebody needs to look into GSK's real reason for paying millions for that research. If resveratrol is like the fountain of youth, the pharmaceutical companies will not want it to be popular with the public. No one would put it past a pharmaceutical company to pay to get rid of a legitimate fountain of youth when they make so much money from pharmaceutical drugs that keep people sick. They pay the researchers, Dr Sinclair looks unethical but he gets paid, and people stop taking resveratrol. It's a win for the pharmaceutical companies. Just a thought.
I am taking Resveratrol and have noticed better sleep, more energy, and clearer thinking and less arthritis pain. I’m hoping my blood work next month will show improvement as well. I’m not taking it for “the fountain of youth effect,” I’m taking it to see if I will feel better….and I do. I’m happy with it. I am on the Mediterranean Diet. Update: I had my blood work done and my physician was surprised at the good results. My A1C dropped significantly so I am no longer pre-diabetic. My cholesterol and LDL, which have been elevated for 12 years, came down about 15 points each which has never happened before and I’d only been taking Resveratrol for about 2 months. Overall, I’m very happy with the results. I will continue with it.
I have researched this myself as well and as someone who really WANTS to trust Dr. Sinclair and appreciates his mantra of aging as a disease it pains to say I agree that his lab is far too biased, invested and perhaps even invented to push this flawed narrative. I appreciate your follow up on this.
Yeah, I've always liked Sinclair too. It's disturbing to see this video here, but sounds thoroughly researched and sincere. I hope Sinclair will reconsider his findings...
The way you caught Dr Sinclair in that lie was pretty great. Thanks for calling this out and bringing it to our attention. I will have a hard time taking him seriously now.
Your honesty and bravery on challenging such established beliefs have made me a loyal follower of your content. I already appreciated your passion for health, but now I also admire your tenacity as well.
Dr. Stanfield is now my go to guy for information on supplements and longevity. I used to follow Sinclair, but now have deleted all of his videos. Thank you Dr. Stanfield for being transparent, admitting when your wrong, and reporting the facts. Thank you!
Excellent investigative reporting Brad. Over the years so many folks were skeptical about resveratrol because both the grape growers and wine makers were heavily funding countless studies and issuing plethoric press releases. Andrew Weil, MD mocked it all decades ago.
@@GizmoFromPizmo Good point. He used to be my number one hero in life until he went MSM..... drink wine, pro-fluoridation, pro-rice, eat soy twice a day, and just only stroll instead of exerting yourself.
Thank you for your explanation of the studies. You have covered this topic very well. Your video about Resveratrol before this one, is why I stopped taking Resveratrol. I had been taking it for at least 8 yrs and I'm glad I found your channel. Thank you very much Dr. Standield.
@@DrBradStanfield Always, I find all your videos useful. What I take instead of Resveratrol is a glutathione supplement. Not sure if you have done a video on glutathione but I would enjoy your take on it. Thanks and keep up the awesome work.
From Subscriber in SE ASIA Simply switch to the Micronized Version with Olive Oil & its proven to be very effective. Follow Dr Sinclair is a rational decision. Many are jealous of his worldwide fame! JIAN & ANDREI PHILIPPINES 🇵🇭 SINGAPORE 🇸🇬 BELOVED MOTHER RUSSIA 🇷🇺
Dear Brad First of all, I’m a big fan and appreciate your publications and critical analysis very much. Without having a medical background, I heavily rely on content like yours to define my personal (longevity) supplement stack. My comment is a summary of an opinion I gathered from a friend at Biolytica and I would love to hear your response, as we don’t think you are covering the story of Resveratrol as objective as it could (and probably should) be - concluding “There’s no human data of health benefits with resveratrol” and “There’s human evidence of harm”. Most of the supporting studies and anecdotal references to podcasts you mention are dated 2008-2013ish. Doing a pubmed search for “RSV and SIRT1”, filtered to only “Human RCTs”, deliver numerous studies that used RSV doses between 150mg and 500mg. The 3rd study (Kitada et al) used Piceatannol not RSV. They were all published 2017-2020 (which is noteworthy since these are far better human RCTs than your quotes which are many in vitro and they are all older studies).

Based on the available data we have to question your research objectivity in this very case. It is long known that RSV and many other mild pro-oxidants increase genes to upregulate production of enzymes that have powerful red-ox, inflammation modulation value through the process of hormesis. Context is critical - and nutrigenomic supplementation must be tested in human clinical trials not petrie dishes. The hormesis issue explains why healthy people might not benefit and why adding 2 xeno-hormetic effects like RSV and exercise might result in too great a pro-oxidant effect (especially more athletic/higher intensity exercise). I don’t try to support or protect any opinion or claim made by David Sinclair. I just try to understand the function and benefits of Resveratrol for myself and my surrounding. Best, Pascal
I really hope Dr. Stanfield replies to this. I'm pretty confused why he has been so anti-resveratrol the last year or so... I'm certainly convinced that it's questionable whether it activates SIRT1, but the positive effects in many of these studies can not be dismissed on the basis of the presence of the fluorescent reagent.
@@OLExGREG Dr Brad is trying to make a name for himself as if he has something to prove, he seems to be totally anti-sinclair and touts info gained from elsewhere, unlike sinclair who is hands on and looks visibly younger as he gets older.
He won’t even address comments like these. Notice he hearts all the ones praising him like just below this comment and literally ignores everyone else. He’s just a narcissist trying to become relevant by making up half truths.
Excellent review presenting all the relevant studies on resveratrol. Thank you 🙏. Certainly GLK wouldn’t have walked away from a billion dollar investment if they had hopes of it showing any positive effects on longevity. This video sure hasn’t helped your chances of getting Dr Sinclair on your show but your viewers appreciate your insights and integrity.
resveratrol cannot be patented and it was superior to all the resveralogues synthesized. It threatens not just one drug but all drugs. That is why it is under attack by big pharma with plenty of trials designed to see it fail. It has extended the lifespan of multiple short lived species, including healthy shorter lived mouse strains. It has even rejuvenated human cells in vitro, researchers surprised and exclaiming it was practically magical the effect it was having. It has failed to extend lifespan likely due to NAD+ decline in longer lived animals, to overcome that it likely needs coadministration with an NAD+ booster. This is because sirtuins need NAD+ and resveratrol works via activation of multiple sirtuins such as sirt6 and sirt4.
I’m not really one to buy into conspiracy theories. I prefer to focus on what the data from well conducted trials show, and to start to produce high quality data as well (through my rapamycin trial)
As a recently relapsed leukemia patient, this is excellent news. I was eating a bag of grapes daily for resveratrol's purported health benefits. I was also consuming large amounts of honey under the obviously false pretense that while it was high in sugar, it could destroy cancer cells (in vitro at least). It is now clear that these bad habits may have contributed to relapse by feeding mass amounts of glucose into the system for leukaemic stem cells to feed on, which is linked to cancer growth as well. When I am released from the hospital this time, I intend to be less brash jumping to conclusions about preliminary research, and stick to a low glucose, low glutamine diet to reduce relapse probability. I thoroughly enjoy your detailed and objective analysis of available research on longevity, so thank you. Sincerely, an appreciative subscriber.
Check out the cancer killing Apple core seeds. The RUclips video I watched said all Apple seeds have a cyanide molecule attached to it that no mammal can detach but all cancer cells tested do detach the cyanide molecules then die immediately. I now eat the whole apple including the core with the seeds blended in. Also, some research shows that Quercetin marks cancer cells and senescent cells with a protein that identifies them as cells to be removed by our immune system. More trials are needed but I take both. No cancers yet for me or my 102 years old father in law.
@@theancientsancients1769 they were for people who read the science. But the problem is the RUclips University students who just watch videos and listen to promos don't know this. Sinclair still pushes it so people still do it. Even WITH all this data, people will still claim it's all wrong and that David Sinclair is right. It's almost like a cult of personality out there.
Sinclair says over and over that Riz Verital must be taken with fat and NMN should be taken with it. He quotes resveratrol is the pedal on the car, and nmn Is the gas could you please speak about that
Then how do you square the GSK trials where they tried to improve absorption of resveratrol and failed? Just taking it with fat doesn't improve the absorption of and is a red-herring argument.
I'm under the impression that the original resveratrol study used extra virgin olive oil as a carrier and it turned out to be synergistic and vital to it's effect. Subsequent studies did not use extra virgin olive oil and didn't get the same results.
@@popothebright In order to duplicate results you have to split hairs the way it was originally conducted. When the Harvard research is done with a particular olive oil and studies "trying" to duplicate it don't use any oil at all it is not useful and may be actually fraudulent. When an oil soluble nutrient is administered with water the nutrient is not as available for digestion. One must split hairs in the exact way the original study did in order to have a valid opinion and/or results.
@@billbucktube I agree... Also my understanding is that low dose vs high dose have the opposite effect... low dose for logevity and high dose for cancer fighting... looks like they were using high dose which doesn't produce the longevity effects
@@Joyces-Favorite-Art-Tutorials Sinclair has stated that the type of fat matters. In his experiment he settled on specifically extra virgin olive oil. When others use “some fat” and get different results it is no surprise. There is a lot of evidence that EVOO is synergistic in action.
Perhaps your best video yet ( I hadn’t seen your earlier video on Resveratrol). I have been taking Resveratrol for years and now I feel like a fool that has been duped. Thank you for the enlightenment. Keep up the good work.
I use Resverotrol and it has increased my exercise endurance ..when I don't take it I feel flat ...it must be taken with fat ..I take mine with yogurt. It definately works.
Heard of the placebo effect? Interesting, positive effects have still been observed in subjects even when they knew they were taking a placebo. How bizarre.
This study was performed to investigate the effects of resveratrol on metabolic status in patients with type 2 diabetes mellitus (T2DM) and coronary heart disease (CHD). This randomized, double-blind, placebo-controlled trial was performed with 56 patients having T2DM and CHD. The patients were randomly divided into two groups to receive either 500 mg resveratrol per day (n = 28) or placebo (n = 28) for 4 weeks. Resveratrol reduced fasting glucose (β-10.04 mg dL-1; 95% CI, -18.23, -1.86; P = 0.01), insulin (β-1.09 μIU mL-1; 95% CI, -1.93, -0.24; P = 0.01) and insulin resistance (β-0.48; 95% CI, -0.76, -0.21; P = 0.001) and significantly increased insulin sensitivity (β 0.006; 95% CI, 0.001, 0.01; P = 0.02) when compared with the placebo. Resveratrol also significantly increased HDL-cholesterol levels (β 3.38 mg dL-1; 95% CI, 1.72, 5.05; P < 0.001) and significantly decreased the total-/HDL-cholesterol ratio (β-0.36; 95% CI, -0.59, -0.13; P = 0.002) when compared with the placebo. Additionally, resveratrol caused a significant increase in total antioxidant capacity (TAC) (β 58.88 mmol L-1; 95% CI, 17.33, 100.44; P = 0.006) and a significant reduction in malondialdehyde (MDA) levels (β-0.21 μmol L-1; 95% CI, -0.41, -0.005; P = 0.04) when compared with the placebo. Resveratrol upregulated PPAR-γ (P = 0.01) and sirtuin 1 (SIRT1) (P = 0.01) in the peripheral blood mononuclear cells (PBMCs) of T2DM patients with CHD. Resveratrol supplementation did not have any effect on inflammatory markers. Four-week supplementation of resveratrol in patients with T2DM and CHD had beneficial effects on glycemic control, HDL-cholesterol levels, the total-/HDL-cholesterol ratio, TAC and MDA levels. Resveratrol also upregulated PPAR-γ and SIRT1 in the PBMCs of T2DM patients with CHD.
At baseline, peripheral blood mononuclear cell H3K56ac values among the SIRT-1 tertiles did not differ. At trial end, SIRT-1 levels were significantly higher in patients receiving 500 mg resveratrol. At follow-up, patients were divided into tertiles of delta (trial end minus baseline) SIRT-1 value. Significant reductions in H3K56ac and body fat percentage were found in the highest tertile as were increased TAS levels. A multiple logistic regression model showed that the highest delta SIRT-1 tertile was inversely associated with variations in H3K56ac (OR = 0.66; 95% CI 0.44-0.99), TAS (OR = 1.01; 95% CI 1.00-1.02), and body fat percentage (OR = 0.75; 95% CI 0.58-0.96).
After watching most of your videos the only thing that stands true for extending your life is eat in moderation, eat healthy, and exercise. I've dropped almost every supplement because of your videos. I appreciate your channel. Thanks so much.
He goes over plenty of supplements that should have benefits for healthspan and/or lifespan. We know K2 lowers the risk of arterial calcification, for a start.
Totally agree, stop to illude ourselves with easy solutions, supplements are not effective for longevity at this time. It’s just business. Lifestyle is the only safe and reasonable intervention, and for me, It should be done with common sense and moderation, in any form. Not drastic fasting or extreme diet, these are Riskier than helpful.
@@DrBradStanfield why don’t you reply to any of the people questioning you Brad??? You were soo quick to judge David for ‘ignoring you’, yet you ignore every single comment even with direct evidence against your piss poor half truths because you’re full of bs trying to get famous for making up controversy. It’s pathetic.
Well my father has memory problems and we have given him resveratrol and it has made a great difference in his memory and ability to function. According to the research out of Australia resveratrol reverses brain aging by 10 years. Let's wait to hear David Sinclair's response lets not be too hasty.
From the testimonies that i have read everywhere is those who have health conditions seems to really benefit from resveratrol. Is your dad still ok taking it?
I understand Dr Brad Stanfield's genuine interest in having enough clarity on this Resveratrol issue, but in order to understand one set of data and be able to compare it to another set of data we need to make sure they are in the same context. I believe that the information presented is incomplete. It does not mention the context in which these tests were carried out and whether they are the same ones that Dr. David Sinclair mentions... that everything is due to scientific rigor.
Well I totally agree with you. My father has severe memory problems we have been giving him a gram and a half of resveratrol every day with olive oil. We have seen a tremendous improvement in his memory. He is able to function at a much higher level. According to the research out of Australia resveratrol decreases brain aging by 10 years. It has done wonders for my father.
Yes, many thousands of people have reported benefits, especially with NMN and oil. I have followed this for years and read of so many instances of people getting younger. It cannot be a coincidence. You can prove anything with studies and I think Dr Bran Stanfield has a bee in his bonnet.
Right. Those studies are over a decade old and since then Sinclair has started studies on monkeys. Also,i was reading an article that suggest the $720 may have more to do with GSK still pursuing resveratrol as a PRESCRIPTION DRUG. Which could make multiple the amount of over the counter. They stopped the two execs from Healthy Lifespan from selling the over the counter brand at cost as a non-profit
Thank you, thank you. I am so tired of "scientists", doctors, etc. doing a little research in labs and then rushing to profit from it by founding companies, etc. Well, unfortunately, I have sometimes bought into it. I now see that I have wasted a lot of money over the years purchasing resveratrol. I appreciate your willingness to expose the supplement hypes.
I appreciate dr Brad Stanfield research and retracting the research on the usefulness of resveterol. I have just bought 2 bottles of the stuff from different sources. Both bottles are unopened. One of them, I already started the process of returning it. The other maybe a little awkward, as bought from USA. I live in London, UK. I do not wish to undo my last 3 months of exercise regime outcome, that I have achieved, after my hip operation and sciatica.
I got a bottle of resveratrol back in 2010. Kept up my normal exercise routine during the cycle, but ended up getting some really bad inflamation in my left elbow about half way through the bottle that caused me to stop training. I had no reason to think resveratrol was the cause, but I figured better safe than sorry & stopped threw out the rest of the bottle. I was just thinking "Its been about 12 years, maybe I just got a bad batch before. I should give it another chance" I loaded up my Amazon cart, ready to go, but then thought I should at least see what other people are saying about it on youtube before I pull the trigger. I'm glad I found this video. That would have been $30 down the drain & possibly kidney failure. My mom is currently recovering from kidney cancer, so I really shouldn't be messing around with this stuff. Thanks for the information!
This is incredibly helpful. When you first debunked the life extending effects of Resveratrol, I tossed my pills. I stopped taking Basis, which is a product with NAD that includes Resveratrol in the formulation (replaced it with Lipo NMN from AlivebyScience). The last thing I need is to blunt the effects of exercise at my age. I greatly appreciate your in depth reviews of these papers. It saves so much time!
Thank you for this video. Sharing negative but balanced data on the popularized interventions in the "alternative" health space are very hard to find. This is a most valuable video!
Would love to see you interview Sinclair for his response. He always says “I will always tell the truth.” I have trusted him unwaveringly. What is the truth???
I don’t know about research but i tried taking Resvetol after listening to dr. David and i clearly see my face looks better and firmer as soon as the next day. I will continue taking it and see if it’s just my head or actually it makes me look younger. I seriously see difference when i take it and see aging signs when i stop taking it
Sinclair's calm delivery and elegant speech certainly won me over on resveratrol. Thank you for exposing the science that was already there to show the guy is no longer scientifically motivated.
Thanks a lot for this video - planted a seed of healthy suspicion in me. I'm so happy RUclips's algorithm suggested this to me even I needed to dig quite deep into the suggestions.
Great video. It conflicts with my initial belief and warrants change. It's nice when published data presented in a clear way can change your mind. Science is not perfect. It’s often misused; it’s only a tool, but it’s the best tool we have. Self-correcting, ever changing, applicable to everything: with this tool, we vanquish the impossible - Carl Sagan
Thank you so much for this. It was very timely for me as I was getting ready to add resveratrol to my vitamin regimen. I appreciate you so much. And I am so disappointed in David Sinclair. I watched your other video of him blocking you. Very troubling. I thought science was about learning and challenging each other. Keep doing what you're doing. I appreciate you!
Great vid! What are your thoughts on why after so many years, no one has done more studies on resveratrol mixed with fat? Since this is Dr. Sincalir's main calim for dismissing all these studies and justifying his results.
that's what i was wondering, there seems to be sinclair talking about fat and not being consulted on it, then sinclair BEING consulted, but only on DOSAGE and not fat
@@delaneyondreams not that i know of! but of course i don't know all. however i remember seeing dr sinclair on a video interview a few years ago, and he spoke of the FALL of resveratrol, and how he stayed in bed for a couple of years, but in the end, he was vindicated.. so these studies could be from the FALL and not from the triumphant come back.. tho i have never seen that interview with sinclair again... maybe it was with tom bilyeu... not sure...
We’ve got human data showing harm when supplementing with Resveratrol. If absorption was the only issue (which it isn’t) then how did those trials detect harm? Also, the idea that GSK threw away ~ $1billion dollars simply because they didn’t think to mix resveratrol with fat is outlandish when you think about it
@@DrBradStanfield you have a point about GSK, i was wondering about that myself, but i wondered if this was some sort of conspiracy lol as far as the trials detecting harm, that COULD be about resveratrol being 'like brick dust without fat'.. brick dust sounds harmful lol i can't take resveratrol, coz of gastrointestinal problems, but when i did, i took it in high doses and i swear i was looking younger, so i can't say i know what is going on
Resveratrol being naturally present in grapes probably needs the other phytochemicals present to provide any benefits. Some things just aren't standalone stars
Ha- I am halfway through my first bottle of resveratrol, so this seems like a good time to stop, thanks so much! At my advanced age I assume any further level of replicative stress is something to do without. Looking up recipes for spinach Greek yogurt dip now.
It is sad that scientists and business people have to re-learn the same lessons they’ve learned before. For example, sunk costs should not, under almost any circumstance, influence future investments. Also, separate your personal identity from what you are studying or investing in. Its tale is as old as science itself and as old as business itself. Just the latest iteration.
This is sad especially for an ex-scientist such as myself. When I was in science I never tried to lie about my results. The results weren't there. I failed and left science for good. But that's life.
That has been my experience as well. It's so easy for someone like Sinclair to deceive laypeople who are not familiar with the ins and outs of basic research.
Very interesting video. I note you focus exclusively on the longevity claims via a single mechanistic pathway. What about the other, non-aging related benefits claimed by NIH and others in the literature? E.g., the “antioxidant, anti-inflammatory, immunomodulatory, glucose and lipid regulatory, neuroprotective, and cardiovascular protective effects” (Meng et. al 2020)?
The thing that really bothers me is Sinclair flat out lying about not being consulted on these studies that show RSV does nothing to extend life. He just lies about it and hopes no one will actually look into it. That is not the first time he has lied about such things. This person cannot be trusted, he is simply not a quality source of information.
I looked into resveratrol studies and accepted that life extension and nootropic claims were unsubstantiated, but decided to take it because of a noted reduction of TMAO, but that's completely negated by raising cholesterol, and blunting the benefit of exercise is unacceptable. Buh bye resveratrol.
@@rosevanderreijden I took pycnogenol on and off a few times and it makes my muscles twitch. I try to search online to see if that’s one of the side effects but I found nothing. Just wondering if that has happened to anyone else.
It's one thing to say that Resv might not be effective activating sirtuin 1, but It is extremely misleading to say that Resv is harmful to humans because it blunts the benefits of exercise. The benefits of exercise is just one facet of the extremely complex makeup of human wellbeing. Im confident that as a doctor, you are aware of the vast amount of data concluding the benefits of intermittent cellular stress such as from fasting and to hot/cold exposure. Separately, I believe it has been stated by Dr. Sinclair and others that the mechanism of Resv is still not completely understood, but that it does show evidence of inducing autophagy, albeit maybe not through activating SIRT1. Please correct me if I am wrong, but isn't autophogy a result of stressed cells? Additionally, autophogy typically occurs after a fasting period where there isn’t as much nutrients being provided to the body. So it makes perfect sense to me that mimicking that state would result in lower physical performance and benefits. Obviously I would have suboptimal performance after not eating for 18 hours, or mimicking the state of fasting.
Could it be that once you sold your “Resveratrol research” company for 720M, you may then be tempted to do anything possible to continue make it look efficient..
Many questions come to my mind now. Resveratrol is found as a natural ingredient in grapes, specially in Pinot Noir. It looks like an ingredient that our body can metabolise well some how. Also it helps out MTOR in our body when doing fasting amd autophagy. My question for you, Dr, is...how all this relates? Thank you
I use low dose of Resveratrol (100 mg/day or 250 mg every other day) to improve ejection fraction of the heart. There is a study on this from Hungarian author Roland Gal in Antioxidants.
Sirtuins are supposed to be NAD+ dependent, so modulating NAD+ should keep surtuins expressed to desired levels without need of supplements (speculation). Afterall, they perform various functions and having suboptimal exprsssion of surtuins, as with many other genes, should work against our health and possibly longevity. I am more interested in SIRT6 which, if I remember correctly, Vera Gornunova discussed as being very useful in reparing double strand DNA breaks, which is impiicated in aging.
Excellent work, Dr. Brad. I have noticed that since starting resveratrol, my workouts have suffered - through it all in the garbage after hearing this.
Great video Brad. Thanks for this excellent review of why resveratrol is actually... less then useless. I had been putting off taking it because of some concerns I had, and this is the first time I have seen those concerns deeply addressed.
I think something what most people forget about resveratrol - is that its working in combination with oil. Without it - its not consumed by our cells(or you need multiple dosage). Same as with carotine.
I have been taking MNM and TMG every morning, and RV (with yogurt) weekdays only, for over a year now. Perhaps I am a outlier but at 61 my VO2 Max has improved over the last year from 25.2 to 31.4. I do only moderate resistance exercise. No HRT just moderate walking.
You’re not an outlier. There are many 60 plus folks out there who are seeing the benefits of what you’re doing. If you’re improving your health, why not continue?
Thank you for this video, it was enough to get me to stop taking resveratrol myself. Been taking in for about a year now and don't notice anything different in my blood work or mood or just overall.
Thank you as always for a very informative video. Please keep us posted about the latest research on NR, NMN, Niacin, TMG .. Basically your supplement stack. Many thanks.
I found a study by Yunjeong Gwon, Jisun Oh & Jong-Sang Kim in 2020 that, as far as I understand it, says that sulforaphane actually increases the growth of colon cancer cells caused by a P53 mutation. So how safe is it to take sulforaphane prophylactically if you don't know if you currently have P53 cancer cells in your colon? I am afraid that I will even accelerate the growth of mutated cells through the increased consumption of sulforaphane.
Thanks Brad! It would be a good thing David Sinclair would share his thoughts on this on your or his channel. David Sinclair could be wrong on Resvertrol, but he still is educating and sharing his knowledge about longevity to the masses. That is a good thing and that is why I admire smart people like you and Sinclair. That's also why I am a loyal follower of you and David.
What does Sinclair share with the masses? Because the repeats the same tropes over and over, ad nauseam. Funny how this "world -renowned longevity scientist" is just discovering the benefits of a WFPB diet. He never misses an opportunity to name-drop however. 🤔
I did find eating red grapes stopped my asthma symptoms. I'm 57 and discovered this by accident 4 or 5 years ago after 50 years of inhalers!!! Anyway I want to live forever so I started taking resveratrol. Thinking it was resveratrol in the grapes that was helping me I stopped eating grapes or drinking grape juice but my asthma symptoms began returning? Excellent video and I will stop taking resveratrol because of it. It's really difficult to know what's best to do. Certainly follow the science but when cash is at stake so is the science. Shell games get played. Let me be clear David Sinclairs lab does excellent work. So I'm not disparaging him or his lab. I'm just a confused ordinary guy. Anyhow great work. Have you looked into Harold Katchers work. Looking like he has the answer.
Quite a thorough, amazing, and convincing video. I've been taking resveratrol for a while, and I've got a new bottle ready to go, but it's going in the trash. With supplements (or even with medicines for that matter) there isn't always research to show their effectiveness, or in cases like this one, researchers are motivated to show certain results, not to find some objective "truth." I'm especially curious to see if my cholesterol will improve after I quit, and if I will see more effects from exercise. If new research ever comes out that reverses the conclusions here, I would consider taking it again, but until that day, you've convinced me to ditch it. Thank you -- this was clearly a lot of work to put together.
Thanks for letting us know the negative effects of rosevertrol. I immediately stopped taking it as soon as I saw your data and feedback. Also my opinion of Dr Sinclair has been negatively affected significantly.
My Vo2 Max actually goes up when taking Nmn+Resveratrol from 55 to ~60 even sometimes over 60. But when i stop taking its constant around 55. Maybe they must always go together.
David Sinclair said in one interview that the tests he has taken show he has a cardio vascular system of someone in their 20s. There must be lots of people who have been taking Resveratrol for years, it would be an interesting study to check them out, see how they are going.
Thank you for this summary of the issues with resveratrol. I suspect, however, that the harms are largely the same as when you take antioxidants or anti-inflammatories with exercise, they counteract the effect of exercise on endogenous production of antioxidants and anti-inflammatories. That is, an exogenous substance like resveratrol/antiox/anti-inflams blocks the training effect.
Since it is known that Resveratrol causes cell stress, why would they do the research on people exercising since exercising causes leads to cell stress albeit a good one? Does it make sense double stressing the cells? It should have been tested on people that are sedentary state to see the effects. Cell stress in moderation can be good because it releases free radicals that are beneficial to the body as long as the free radicle release is moderated. I mean it starts becoming damaging of in excess. Also why did they not mix it why oils since it gets absorbed better with oils? There are folks that have benefitted greatly from this supplement so even though research seems to say otherwise, there is still something being missed. Maybe dosage affects different people. It’s good you dud the video so people can look at all the data and make an informed decision.
Its great you've shed light on extreme claims for resveratrol, but it would have been REALLY helpful to let those of us know that may have supplies of it, of any other valid uses for it.....SURELY it is of "some" measure of benifit for something/anything, perhaps duodendritic recovery spans?...
Glad I found your channel as I’ve just been introduced to this stuff. Interesting about the Resveratrol absorption issue and normal food because I heard Sinclair say recently, and I think this may be his “work around” to validate it, that it is best to pair it with intermittent fasting and taken every second day not every day. Standing on its own you think great, ok, that’s the protocol . But hearing it now in light of what you’ve found makes me see it in a very different light.
Dr. Brad: Maybe I missed it, but did those later studies on mice attempt to deliver the Resveritrol with fats, as Sinclair advised? I was unclear on that. That would at least show that the catalyst was a factor.
Wow…Dr Brad! Excellent critical review and analysis on the latest research available on Resveratrol benefits!!! You are a HERO in the anti-aging community!!!
A few weeks into taking a small dose of trans resveratrol I developed joint and muscle pain, to the point I thought I might have a neurological or autoimmune condition. After my bottle ended and i didn't buy more, I noticed all the symptoms stopped. Regardless of who is right in this discussion, I think it's more than safe to say there is no miracle substance, especially not for everyone.
seems that many theories of doctor sinclair are being destroyed on this channel, but seems also undeniable that sinclair got biologically younger doing what he does, so i wonder what is really working in making him much healthy, i have a an idea about that, could someone leave his thought here?
Really world class detailed analysis. I will cease using Resveratrol supplements immediately. Well, not entirely. I do plan to continue consuming moderate amounts of wine and grapes. Lol
Thank you for the video. Was there an attempt by David Sinclair to differentiate between taking resveratrol with a “normal diet” vs taking it with olive oil or yogurt?
@@scotte9384 Thanks. My question is whether DS is saying Resveratrol works with fatty options vs a normal diet. He seemed to attempt for that distinction in his clip but from what I could tell, this video ignored that detail.
He was directly consulted on the dosing. Can’t imagine he wouldn’t have mentioned, let alone stressed the fat absorption enhancement. He’s always yammering on about it whenever he’s promulgating the compound on podcasts, while not lying about his involvement with the study.
It took courage to call out Dr. Sinclair, a perceived “giant” in the anti-aging field. Thank you
Thanks for watching and leaving a comment
@Dr Brad Stanfield is there any validity for claims that Resveratrol increases Nitric Oxide production, improves genetic health, protects brain from cell damage and makes blood fats healthier?
I purchased Resveratrol from Eternum Labs and these claims are on the container with further claims for Resveratrol on the website.
Thanks for speaking out!
Agree. I am done wasting my money on resveratrol.
@@SeriouslyWeirdDream beet juice lowered my BP, but it’s a shame that it tastes so nasty,.
remember, that even Doc Since. says - hey I am self experimenting on myself...There is a risk.. A lot of this stuff is theoretical! I think the disagreements are very important, to get to the truth! Colelctively - Berg, Ekberg, Stanfield, Sinclair.... all these channels are insanely good! They all could be related....even the names ..in a way...
this is why I subscribe to the Dr Stanfield channel. He has no fear reporting current studies bringing the largest of youTube whales or nutritional sacred cows into question... including his own past recommendations! He DOES let the facts "get in the way"; how admirable and edifying.
THanks :-)
Dr. Stan field is one of the best. I love Valter Longo too.
What about NMN, is that effective??
He's great. But I take him with a grain of salt. He is very bias towards "healthspan", so much so, that he compromises lifespan.
He puts too much emphasis on consuming protein & muscle building, which is proven to promote ageing.
@@jeffjohnson5053 great question that is what Dr Sinclair preaches is the combination of nmn to produce nad+
Although the ITP did consult with Sinclair, you didn't address the fact that they just gave the resveratrol to the mice in food without mixing it with fat. As Sinclair said, in their own studies giving it to the mice in regular food without fat didn't extend lifespan.
Surely David Sinclair should have volunteered such critical information to the ITP without being asked. After all he would have an invested interest in this trial showing life extention benefits under such conditions.
Exactly what I was thinking, the most interesting question raised. I'm still waiting on the punchline.
Sinclair is listed as one of the authors on the ITP paper: www.ncbi.nlm.nih.gov/pmc/articles/PMC3598361/
They mixed it in the food (aka: chow) which has more than enough fat.
@@adrianboyddodd8007 yup. But then hundreds of millions of dollars in buy out cash would shut most people’s mouths…
I have been taking Resveratrol since November 2021. My anxiety disappeared and I slept much better - that was he first thing I noticed. Then my energy levels increased - my body seemed to start craving exercise. I don’t think I am imagining any of this. I have noticed no side effects so far.
How much of Resveratrol have you been taking? 500mg?
I experience profound benefits with Japanese Knotweed, but I understand that my case might be very specific. I don’t think this video necessarily implies that resveratrol as a compound has no therapeutic usage at all. For instance it appears that Japanese knotweed has some antimicrobial and immuno-modulating effects (whether that’s purely from resveratrol or from the combination of compounds I don’t know). Same as chemotherapy might be useful for some people.
I've been taking it for over a year now and I too thought that I have been improving.
I think somebody needs to look into GSK's real reason for paying millions for that research. If resveratrol is like the fountain of youth, the pharmaceutical companies will not want it to be popular with the public. No one would put it past a pharmaceutical company to pay to get rid of a legitimate fountain of youth when they make so much money from pharmaceutical drugs that keep people sick. They pay the researchers, Dr Sinclair looks unethical but he gets paid, and people stop taking resveratrol. It's a win for the pharmaceutical companies.
Just a thought.
As interesting as that is, it's anecdotal and nobody can verify the variables our data for said results. Thanks for sharing, though.
I am taking Resveratrol and have noticed better sleep, more energy, and clearer thinking and less arthritis pain. I’m hoping my blood work next month will show improvement as well. I’m not taking it for “the fountain of youth effect,” I’m taking it to see if I will feel better….and I do. I’m happy with it. I am on the Mediterranean Diet.
Update: I had my blood work done and my physician was surprised at the good results. My A1C dropped significantly so I am no longer pre-diabetic. My cholesterol and LDL, which have been elevated for 12 years, came down about 15 points each which has never happened before and I’d only been taking Resveratrol for about 2 months. Overall, I’m very happy with the results. I will continue with it.
I have researched this myself as well and as someone who really WANTS to trust Dr. Sinclair and appreciates his mantra of aging as a disease it pains to say I agree that his lab is far too biased, invested and perhaps even invented to push this flawed narrative.
I appreciate your follow up on this.
When they have an agenda they can twist the research to fit it. Crazy.

Excellent investigative reporting Brad. Over the years so many folks were skeptical about resveratrol because both the grape growers and wine makers were heavily funding countless studies and issuing plethoric press releases. Andrew Weil, MD mocked it all decades ago.

Dear Brad
First of all, I’m a big fan and appreciate your publications and critical analysis very much. Without having a medical background, I heavily rely on content like yours to define my personal (longevity) supplement stack. My comment is a summary of an opinion I gathered from a friend at Biolytica and I would love to hear your response, as we don’t think you are covering the story of Resveratrol as objective as it could (and probably should) be - concluding “There’s no human data of health benefits with resveratrol” and “There’s human evidence of harm”.

Based on the available data we have to question your research objectivity in this very case. It is long known that RSV and many other mild pro-oxidants increase genes to upregulate production of enzymes that have powerful red-ox, inflammation modulation value through the process of hormesis. Context is critical - and nutrigenomic supplementation must be tested in human clinical trials not petrie dishes.
The hormesis issue explains why healthy people might not benefit and why adding 2 xeno-hormetic effects like RSV and exercise might result in too great a pro-oxidant effect (especially more athletic/higher intensity exercise).
I don’t try to support or protect any opinion or claim made by David Sinclair. I just try to understand the function and benefits of Resveratrol for myself and my surrounding.
Best,
Pascal
Give this man his respect. His name is Dr. S, he wouldn’t be able to critically analyze and provide you this free content without that degree.
I really hope Dr. Stanfield replies to this. I'm pretty confused why he has been so anti-resveratrol the last year or so... I'm certainly convinced that it's questionable whether it activates SIRT1, but the positive effects in many of these studies can not be dismissed on the basis of the presence of the fluorescent reagent.

resveratrol cannot be patented and it was superior to all the resveralogues synthesized. It threatens not just one drug but all drugs. That is why it is under attack by big pharma with plenty of trials designed to see it fail. It has extended the lifespan of multiple short lived species, including healthy shorter lived mouse strains. It has even rejuvenated human cells in vitro, researchers surprised and exclaiming it was practically magical the effect it was having. It has failed to extend lifespan likely due to NAD+ decline in longer lived animals, to overcome that it likely needs coadministration with an NAD+ booster. This is because sirtuins need NAD+ and resveratrol works via activation of multiple sirtuins such as sirt6 and sirt4.
@@diamond_s Dr. Stanfield - would you like to address this?
I’m not really one to buy into conspiracy theories. I prefer to focus on what the data from well conducted trials show, and to start to produce high quality data as well (through my rapamycin trial)
This was an outstanding review. A lot of people have wasted a lot of money taking resveratrol for over a decade or more.
Highly appreciated that u make a video on this controversial topic.
As a recently relapsed leukemia patient, this is excellent news. I was eating a bag of grapes daily for resveratrol's purported health benefits. I was also consuming large amounts of honey under the obviously false pretense that while it was high in sugar, it could destroy cancer cells (in vitro at least). It is now clear that these bad habits may have contributed to relapse by feeding mass amounts of glucose into the system for leukaemic stem cells to feed on, which is linked to cancer growth as well. When I am released from the hospital this time, I intend to be less brash jumping to conclusions about preliminary research, and stick to a low glucose, low glutamine diet to reduce relapse probability. I thoroughly enjoy your detailed and objective analysis of available research on longevity, so thank you. Sincerely, an appreciative subscriber.
Grapes are some of the worst fruits to eat, they spike your glucose levels immensly. To be fair, Sinclair himself has said that in an interview.
Taking high sugar foodstuffs is horrible for people with cancer. Whole plant diet.
Check out the cancer killing Apple core seeds. The RUclips video I watched said all Apple seeds have a cyanide molecule attached to it that no mammal can detach but all cancer cells tested do detach the cyanide molecules then die immediately. I now eat the whole apple including the core with the seeds blended in. Also, some research shows that Quercetin marks cancer cells and senescent cells with a protein that identifies them as cells to be removed by our immune system. More trials are needed but I take both. No cancers yet for me or my 102 years old father in law.

I'm under the impression that the original resveratrol study used extra virgin olive oil as a carrier and it turned out to be synergistic and vital to it's effect. Subsequent studies did not use extra virgin olive oil and didn't get the same results.

We're splitting hairs now.
@@popothebright In order to duplicate results you have to split hairs the way it was originally conducted. When the Harvard research is done with a particular olive oil and studies "trying" to duplicate it don't use any oil at all it is not useful and may be actually fraudulent. When an oil soluble nutrient is administered with water the nutrient is not as available for digestion. One must split hairs in the exact way the original study did in order to have a valid opinion and/or results.

Resveratrol reduced fasting glucose (β-10.04 mg dL-1; 95% CI, -18.23, -1.86; P = 0.01), insulin (β-1.09 μIU mL-1; 95% CI, -1.93, -0.24; P = 0.01) and insulin resistance (β-0.48; 95% CI, -0.76, -0.21; P = 0.001) and significantly increased insulin sensitivity (β 0.006; 95% CI, 0.001, 0.01; P = 0.02) when compared with the placebo. Resveratrol also significantly increased HDL-cholesterol levels (β 3.38 mg dL-1; 95% CI, 1.72, 5.05; P < 0.001) and significantly decreased the total-/HDL-cholesterol ratio (β-0.36; 95% CI, -0.59, -0.13; P = 0.002) when compared with the placebo. Additionally, resveratrol caused a significant increase in total antioxidant capacity (TAC) (β 58.88 mmol L-1; 95% CI, 17.33, 100.44; P = 0.006) and a significant reduction in malondialdehyde (MDA) levels (β-0.21 μmol L-1; 95% CI, -0.41, -0.005; P = 0.04) when compared with the placebo. Resveratrol upregulated PPAR-γ (P = 0.01) and sirtuin 1 (SIRT1) (P = 0.01) in the peripheral blood mononuclear cells (PBMCs) of T2DM patients with CHD. Resveratrol supplementation did not have any effect on inflammatory markers. Four-week supplementation of resveratrol in patients with T2DM and CHD had beneficial effects on glycemic control, HDL-cholesterol levels, the total-/HDL-cholesterol ratio, TAC and MDA levels. Resveratrol also upregulated PPAR-γ and SIRT1 in the PBMCs of T2DM patients with CHD.
At baseline, peripheral blood mononuclear cell H3K56ac values among the SIRT-1 tertiles did not differ. At trial end, SIRT-1 levels were significantly higher in patients receiving 500 mg resveratrol. At follow-up, patients were divided into tertiles of delta (trial end minus baseline) SIRT-1 value. Significant reductions in H3K56ac and body fat percentage were found in the highest tertile as were increased TAS levels. A multiple logistic regression model showed that the highest delta SIRT-1 tertile was inversely associated with variations in H3K56ac (OR = 0.66; 95% CI 0.44-0.99), TAS (OR = 1.01; 95% CI 1.00-1.02), and body fat percentage (OR = 0.75; 95% CI 0.58-0.96).
After watching most of your videos the only thing that stands true for extending your life is eat in moderation, eat healthy, and exercise. I've dropped almost every supplement because of your videos. I appreciate your channel. Thanks so much.
And fasting?
He goes over plenty of supplements that should have benefits for healthspan and/or lifespan. We know K2 lowers the risk of arterial calcification, for a start.
Totally agree, stop to illude ourselves with easy solutions, supplements are not effective for longevity at this time. It’s just business. Lifestyle is the only safe and reasonable intervention, and for me,
It should be done with common sense and moderation, in any form. Not drastic fasting or extreme diet, these are
Riskier than helpful.
NAD boosters and AKG, Rapamycin seem to be very effective in lifespan extension.
Absolutely Sean
Another great video.
Admire your honesty .
I was about to place an order resvertaral
Thank you Dr. Brad. It’s amazing how all the data is there but can still be hidden. Your research is so helpful.
Thanks, glad to hear you found the video useful
@@DrBradStanfield why don’t you reply to any of the people questioning you Brad??? You were soo quick to judge David for ‘ignoring you’, yet you ignore every single comment even with direct evidence against your piss poor half truths because you’re full of bs trying to get famous for making up controversy. It’s pathetic.
thanks Dr Brad. you really help the community anti-aging. You have the courage to face the real facts.
Dont listen to Brad, you gonna ,ne stirred away from something good for your health,he's probably a dr that's working for the big pham.
Well my father has memory problems and we have given him resveratrol and it has made a great difference in his memory and ability to function. According to the research out of Australia resveratrol reverses brain aging by 10 years. Let's wait to hear David Sinclair's response lets not be too hasty.
Wouldn’t this surely had shown up as a positive effect on lifespan in tests?
it is because of the acetylcholinesterase inhibitor effect you have multiple herb and substance with the same effect without the bad.
@@rayquaza6791 explain please
From the testimonies that i have read everywhere is those who have health conditions seems to really benefit from resveratrol. Is your dad still ok taking it?
This is important stuff. Thank you!
I understand Dr Brad Stanfield's genuine interest in having enough clarity on this Resveratrol issue, but in order to understand one set of data and be able to compare it to another set of data we need to make sure they are in the same context. I believe that the information presented is incomplete. It does not mention the context in which these tests were carried out and whether they are the same ones that Dr. David Sinclair mentions... that everything is due to scientific rigor.
how much more complete doe sit need to be?
Well I totally agree with you. My father has severe memory problems we have been giving him a gram and a half of resveratrol every day with olive oil. We have seen a tremendous improvement in his memory. He is able to function at a much higher level. According to the research out of Australia resveratrol decreases brain aging by 10 years. It has done wonders for my father.
There’s no way that GSK just walks away from a billion dollars and they have an army of scientists. Use your head.
Yes, many thousands of people have reported benefits, especially with NMN and oil. I have followed this for years and read of so many instances of people getting younger. It cannot be a coincidence. You can prove anything with studies and I think Dr Bran Stanfield has a bee in his bonnet.
Right. Those studies are over a decade old and since then Sinclair has started studies on monkeys. Also,i was reading an article that suggest the $720 may have more to do with GSK still pursuing resveratrol as a PRESCRIPTION DRUG. Which could make multiple the amount of over the counter. They stopped the two execs from Healthy Lifespan from selling the over the counter brand at cost as a non-profit
you have earned my subscription with this one video. never heard this other side of the argument regarding resveratrol.
Thank you, thank you. I am so tired of "scientists", doctors, etc. doing a little research in labs and then rushing to profit from it by founding companies, etc.
Well, unfortunately, I have sometimes bought into it. I now see that I have wasted a lot of money over the years purchasing resveratrol.
I appreciate your willingness to expose the supplement hypes.
Thanks for the comment Charles
I appreciate dr Brad Stanfield research and retracting the research on the usefulness of resveterol. I have just bought 2 bottles of the stuff from different sources. Both bottles are unopened. One of them, I already started the process of returning it. The other maybe a little awkward, as bought from USA. I live in London, UK. I do not wish to undo my last 3 months of exercise regime outcome, that I have achieved, after my hip operation and sciatica.
I'm also sick of this f***ing RUclips doctors , for every study that says something is healty there is anothet saying the oposite
Since I can’t read scientific papers, I’m in a weak position to decide which brilliant scientist is right when they don’t agree.
I got a bottle of resveratrol back in 2010. Kept up my normal exercise routine during the cycle, but ended up getting some really bad inflamation in my left elbow about half way through the bottle that caused me to stop training. I had no reason to think resveratrol was the cause, but I figured better safe than sorry & stopped threw out the rest of the bottle.
I was just thinking "Its been about 12 years, maybe I just got a bad batch before. I should give it another chance" I loaded up my Amazon cart, ready to go, but then thought I should at least see what other people are saying about it on youtube before I pull the trigger.
I'm glad I found this video. That would have been $30 down the drain & possibly kidney failure. My mom is currently recovering from kidney cancer, so I really shouldn't be messing around with this stuff. Thanks for the information!
Ditching my resveratrol. Thank you for your video.
This is incredibly helpful. When you first debunked the life extending effects of Resveratrol, I tossed my pills. I stopped taking Basis, which is a product with NAD that includes Resveratrol in the formulation (replaced it with Lipo NMN from AlivebyScience). The last thing I need is to blunt the effects of exercise at my age. I greatly appreciate your in depth reviews of these papers. It saves so much time!
Thank you for this video. Sharing negative but balanced data on the popularized interventions in the "alternative" health space are very hard to find. This is a most valuable video!
Glad you enjoyed the video
Would love to see you interview Sinclair for his response. He always says “I will always tell the truth.” I have trusted him unwaveringly. What is the truth???
I don’t know about research but i tried taking Resvetol after listening to dr. David and i clearly see my face looks better and firmer as soon as the next day. I will continue taking it and see if it’s just my head or actually it makes me look younger. I seriously see difference when i take it and see aging signs when i stop taking it
Sinclair's calm delivery and elegant speech certainly won me over on resveratrol. Thank you for exposing the science that was already there to show the guy is no longer scientifically motivated.
Thanks for watching and for leaving a comment
one thing is certain and is that he rehearsed his commercial spitch well
I think he will become more motivated as the years pass by and time runs out. But first he is a salesman, thats obvious if you hear him talk .
Probably financially motivated, he is finally honouring his ashkenazi ancestors lol .

Thanks a lot for this video - planted a seed of healthy suspicion in me. I'm so happy RUclips's algorithm suggested this to me even I needed to dig quite deep into the suggestions.
Great video. It conflicts with my initial belief and warrants change. It's nice when published data presented in a clear way can change your mind.

Thank you so much for this. It was very timely for me as I was getting ready to add resveratrol to my vitamin regimen. I appreciate you so much. And I am so disappointed in David Sinclair. I watched your other video of him blocking you. Very troubling. I thought science was about learning and challenging each other. Keep doing what you're doing. I appreciate you!
Great vid! What are your thoughts on why after so many years, no one has done more studies on resveratrol mixed with fat? Since this is Dr. Sincalir's main calim for dismissing all these studies and justifying his results.
that's what i was wondering, there seems to be sinclair talking about fat and not being consulted on it, then sinclair BEING consulted, but only on DOSAGE and not fat
@@elaineremains So has no one replicated his studies or studied Resveratrol by mixing first in fat?? No One?
@@delaneyondreams not that i know of! but of course i don't know all. however i remember seeing dr sinclair on a video interview a few years ago, and he spoke of the FALL of resveratrol, and how he stayed in bed for a couple of years, but in the end, he was vindicated.. so these studies could be from the FALL and not from the triumphant come back.. tho i have never seen that interview with sinclair again... maybe it was with tom bilyeu... not sure...
We’ve got human data showing harm when supplementing with Resveratrol. If absorption was the only issue (which it isn’t) then how did those trials detect harm? Also, the idea that GSK threw away ~ $1billion dollars simply because they didn’t think to mix resveratrol with fat is outlandish when you think about it
@@DrBradStanfield you have a point about GSK, i was wondering about that myself, but i wondered if this was some sort of conspiracy lol
as far as the trials detecting harm, that COULD be about resveratrol being 'like brick dust without fat'.. brick dust sounds harmful lol
i can't take resveratrol, coz of gastrointestinal problems, but when i did, i took it in high doses and i swear i was looking younger, so i can't say i know what is going on
Resveratrol being naturally present in grapes probably needs the other phytochemicals present to provide any benefits. Some things just aren't standalone stars
🙌 👏 🙏 🤝 👍
Ha- I am halfway through my first bottle of resveratrol, so this seems like a good time to stop, thanks so much! At my advanced age I assume any further level of replicative stress is something to do without. Looking up recipes for spinach Greek yogurt dip now.
Wow, you've made some very good observations. Just shows once again that you cant blindly trust no one.
It is sad that scientists and business people have to re-learn the same lessons they’ve learned before. For example, sunk costs should not, under almost any circumstance, influence future investments. Also, separate your personal identity from what you are studying or investing in. Its tale is as old as science itself and as old as business itself. Just the latest iteration.
I have 5 pills left, getting rid of them NOW. You just saved me money, as I was considering to step up my intake.
This is sad especially for an ex-scientist such as myself. When I was in science I never tried to lie about my results. The results weren't there. I failed and left science for good. But that's life.
That has been my experience as well. It's so easy for someone like Sinclair to deceive laypeople who are not familiar with the ins and outs of basic research.
"Science" should not be blamed for what soi-disant scientists do in its name. Science is like religion, most of the devotees are anything but saints.
Very interesting video. I note you focus exclusively on the longevity claims via a single mechanistic pathway. What about the other, non-aging related benefits claimed by NIH and others in the literature? E.g., the “antioxidant, anti-inflammatory, immunomodulatory, glucose and lipid regulatory, neuroprotective, and cardiovascular protective effects” (Meng et. al 2020)?
The thing that really bothers me is Sinclair flat out lying about not being consulted on these studies that show RSV does nothing to extend life. He just lies about it and hopes no one will actually look into it. That is not the first time he has lied about such things. This person cannot be trusted, he is simply not a quality source of information.
I suspect that Sinclair sells these products he pushes.
This channel has the most honest and reliable information on the internet.
I looked into resveratrol studies and accepted that life extension and nootropic claims were unsubstantiated, but decided to take it because of a noted reduction of TMAO, but that's completely negated by raising cholesterol, and blunting the benefit of exercise is unacceptable. Buh bye resveratrol.

This is why I luv your channel, pure science no ideology
The power of the peer reviewed system is a beautiful thing.
Thank you Dr. Brad for going through the research papers and podcast to provide an updated information on resveratrol.
It's one thing to say that Resv might not be effective activating sirtuin 1, but It is extremely misleading to say that Resv is harmful to humans because it blunts the benefits of exercise. The benefits of exercise is just one facet of the extremely complex makeup of human wellbeing. Im confident that as a doctor, you are aware of the vast amount of data concluding the benefits of intermittent cellular stress such as from fasting and to hot/cold exposure.
Separately, I believe it has been stated by Dr. Sinclair and others that the mechanism of Resv is still not completely understood, but that it does show evidence of inducing autophagy, albeit maybe not through activating SIRT1. Please correct me if I am wrong, but isn't autophogy a result of stressed cells?
Additionally, autophogy typically occurs after a fasting period where there isn’t as much nutrients being provided to the body. So it makes perfect sense to me that mimicking that state would result in lower physical performance and benefits. Obviously I would have suboptimal performance after not eating for 18 hours, or mimicking the state of fasting.
🙌 👏 🙏 🤝 👍What a real GREAT cmment. I do n o t trust man, I trust mother NATURE (aka GOD)
You are wrong @Dr Brad Stanfield. Reveratrol activates Sirt1 indirectly through ampk, no one ever claimed it would activate it directly.
Could it be that once you sold your “Resveratrol research” company for 720M, you may then be tempted to do anything possible to continue make it look efficient..
Many questions come to my mind now. Resveratrol is found as a natural ingredient in grapes, specially in Pinot Noir. It looks like an ingredient that our body can metabolise well some how. Also it helps out MTOR in our body when doing fasting amd autophagy. My question for you, Dr, is...how all this relates? Thank you
What we need is a study on resveratrol taken in conjunction with NMN as Sinclair says that's key to get the most out of NMN's benefits.
Very good point: synergistic effects.
I use low dose of Resveratrol (100 mg/day or 250 mg every other day) to improve ejection fraction of the heart. There is a study on this from Hungarian author Roland Gal in Antioxidants.
Mind blowing! Worked in the supplement industry and wondered why the wonder nutrient virtually disappeared. Incredible story thanks
One of the best videos from Dr. Stanfield I've seen. Thank you. I love this channel.
Sirtuins are supposed to be NAD+ dependent, so modulating NAD+ should keep surtuins expressed to desired levels without need of supplements (speculation). Afterall, they perform various functions and having suboptimal exprsssion of surtuins, as with many other genes, should work against our health and possibly longevity. I am more interested in SIRT6 which, if I remember correctly, Vera Gornunova discussed as being very useful in reparing double strand DNA breaks, which is impiicated in aging.
Excellent work, Dr. Brad. I have noticed that since starting resveratrol, my workouts have suffered - through it all in the garbage after hearing this.
Great video Brad. Thanks for this excellent review of why resveratrol is actually... less then useless. I had been putting off taking it because of some concerns I had, and this is the first time I have seen those concerns deeply addressed.
I think something what most people forget about resveratrol - is that its working in combination with oil. Without it - its not consumed by our cells(or you need multiple dosage). Same as with carotine.
In David Sinclair podcast this week he was still talking about resveratrol as a proven anti ager
Clearly we need more research to address these questions.
You missed what Dr.. Sinclair told Dr. Peter Attia and then spun in a different direction. Why?
I have been taking MNM and TMG every morning, and RV (with yogurt) weekdays only, for over a year now. Perhaps I am a outlier but at 61 my VO2 Max has improved over the last year from 25.2 to 31.4. I do only moderate resistance exercise. No HRT just moderate walking.
Imputs like this are also needed, in order to have a complete image. Thx
You’re not an outlier. There are many 60 plus folks out there who are seeing the benefits of what you’re doing. If you’re improving your health, why not continue?
Thank you for this video, it was enough to get me to stop taking resveratrol myself. Been taking in for about a year now and don't notice anything different in my blood work or mood or just overall.
Thank you as always for a very informative video. Please keep us posted about the latest research on NR, NMN, Niacin, TMG .. Basically your supplement stack. Many thanks.
I found a study by Yunjeong Gwon, Jisun Oh & Jong-Sang Kim in 2020 that, as far as I understand it, says that sulforaphane actually increases the growth of colon cancer cells caused by a P53 mutation.
So how safe is it to take sulforaphane prophylactically if you don't know if you currently have P53 cancer cells in your colon? I am afraid that I will even accelerate the growth of mutated cells through the increased consumption of sulforaphane.
Thanks Brad! It would be a good thing David Sinclair would share his thoughts on this on your or his channel. David Sinclair could be wrong on Resvertrol, but he still is educating and sharing his knowledge about longevity to the masses. That is a good thing and that is why I admire smart people like you and Sinclair. That's also why I am a loyal follower of you and David.
What does Sinclair share with the masses? Because the repeats the same tropes over and over, ad nauseam. Funny how this "world -renowned longevity scientist" is just discovering the benefits of a WFPB diet. He never misses an opportunity to name-drop however. 🤔
I did find eating red grapes stopped my asthma symptoms. I'm 57 and discovered this by accident 4 or 5 years ago after 50 years of inhalers!!!
Anyway I want to live forever so I started taking resveratrol. Thinking it was resveratrol in the grapes that was helping me I stopped eating grapes or drinking grape juice but my asthma symptoms began returning?
Excellent video and I will stop taking resveratrol because of it. It's really difficult to know what's best to do. Certainly follow the science but when cash is at stake so is the science.
Shell games get played.
Let me be clear David Sinclairs lab does excellent work. So I'm not disparaging him or his lab. I'm just a confused ordinary guy.
Anyhow great work. Have you looked into Harold Katchers work. Looking like he has the answer.
Quite a thorough, amazing, and convincing video. I've been taking resveratrol for a while, and I've got a new bottle ready to go, but it's going in the trash. With supplements (or even with medicines for that matter) there isn't always research to show their effectiveness, or in cases like this one, researchers are motivated to show certain results, not to find some objective "truth." I'm especially curious to see if my cholesterol will improve after I quit, and if I will see more effects from exercise. If new research ever comes out that reverses the conclusions here, I would consider taking it again, but until that day, you've convinced me to ditch it. Thank you -- this was clearly a lot of work to put together.
Thanks for letting us know the negative effects of rosevertrol. I immediately stopped taking it as soon as I saw your data and feedback.
Also my opinion of Dr Sinclair has been negatively affected significantly.
My Vo2 Max actually goes up when taking Nmn+Resveratrol from 55 to ~60 even sometimes over 60. But when i stop taking its constant around 55.
Maybe they must always go together.
Thanks for your dedication Dr Brad. This is great information. Just, threw my resveratrol down the toilet.
David Sinclair said in one interview that the tests he has taken show he has a cardio vascular system of someone in their 20s. There must be lots of people who have been taking Resveratrol for years, it would be an interesting study to check them out, see how they are going.
David sinclair does many things to slow aging including timed eating. Difficult to pin his gains on just one thing.
@@projimbo pp
Brad is too young to understand the world....
Who cares what Sinclair said, I'm only interested in what he can prove
Thank you for this summary of the issues with resveratrol. I suspect, however, that the harms are largely the same as when you take antioxidants or anti-inflammatories with exercise, they counteract the effect of exercise on endogenous production of antioxidants and anti-inflammatories. That is, an exogenous substance like resveratrol/antiox/anti-inflams blocks the training effect.
Since it is known that Resveratrol causes cell stress, why would they do the research on people exercising since exercising causes leads to cell stress albeit a good one? Does it make sense double stressing the cells? It should have been tested on people that are sedentary state to see the effects. Cell stress in moderation can be good because it releases free radicals that are beneficial to the body as long as the free radicle release is moderated. I mean it starts becoming damaging of in excess. Also why did they not mix it why oils since it gets absorbed better with oils? There are folks that have benefitted greatly from this supplement so even though research seems to say otherwise, there is still something being missed. Maybe dosage affects different people. It’s good you dud the video so people can look at all the data and make an informed decision.
Its great you've shed light on extreme claims for resveratrol, but it would have been REALLY helpful to let those of us know that may have supplies of it, of any other valid uses for it.....SURELY it is of "some" measure of benifit for something/anything, perhaps duodendritic recovery spans?...
Glad I found your channel as I’ve just been introduced to this stuff. Interesting about the Resveratrol absorption issue and normal food because I heard Sinclair say recently, and I think this may be his “work around” to validate it, that it is best to pair it with intermittent fasting and taken every second day not every day. Standing on its own you think great, ok, that’s the protocol . But hearing it now in light of what you’ve found makes me see it in a very different light.
Thats a nice find. I was postponing taking Resveratrol constantly and now it seems I will never take it.
Dr. Brad:
Maybe I missed it, but did those later studies on mice attempt to deliver the Resveritrol with fats, as Sinclair advised? I was unclear on that. That would at least show that the catalyst was a factor.
Wow…Dr Brad! Excellent critical review and analysis on the latest research available on Resveratrol benefits!!! You are a HERO in the anti-aging community!!!
Very well done doc. We need more of this about supplements and disease. Tanks a lot.
Is olive oil good then? does it also stress us alot?
A few weeks into taking a small dose of trans resveratrol I developed joint and muscle pain, to the point I thought I might have a neurological or autoimmune condition. After my bottle ended and i didn't buy more, I noticed all the symptoms stopped. Regardless of who is right in this discussion, I think it's more than safe to say there is no miracle substance, especially not for everyone.
Yes i have same problem after 15 days starting back pain. Now i want to stop it.
seems that many theories of doctor sinclair are being destroyed on this channel, but seems also undeniable that sinclair got biologically younger doing what he does, so i wonder what is really working in making him much healthy, i have a an idea about that, could someone leave his thought here?
Really world class detailed analysis. I will cease using Resveratrol supplements immediately. Well, not entirely. I do plan to continue consuming moderate amounts of wine and grapes. Lol
Helpful. Thank you
Thank you for the video. Was there an attempt by David Sinclair to differentiate between taking resveratrol with a “normal diet” vs taking it with olive oil or yogurt?
The olive oil or yogurt just provides some fat for it to dissolve into.Fat soluble supplements are MUCH better absorbed when consumed w fats.
@@scotte9384 Thanks. My question is whether DS is saying Resveratrol works with fatty options vs a normal diet. He seemed to attempt for that distinction in his clip but from what I could tell, this video ignored that detail.
He was directly consulted on the dosing. Can’t imagine he wouldn’t have mentioned, let alone stressed the fat absorption enhancement. He’s always yammering on about it whenever he’s promulgating the compound on podcasts, while not lying about his involvement with the study.
Thank you Dr. Stanfield. Thank for your courage and integrity.
