• Her thoughts on the following study claiming people taking fish oil have an increased risk of atrial fibrillation and stroke: bmjmedicine.bm...
• The difference between relative & absolute risk when it comes to fish oil & AFib
• Why, even if fish oil increases AFib risk, it also lowers risk of coronary heart disease, kidney stones, liver cancer, dementia, cardiovascular-related morality, and all-cause mortality
• Why she doesn't recommend free fatty acid form omega-3
• Her omega-3/fish oil intake recommendations given the totality of the scientific evidence

I ate fish, mainly salmon, but also cod everyday for a month until I felt a tickle in my left upper chest for two or three nights... I stopped and its gone. Yes it is dose dependent. Don't over do it.
@@yellads A self diagnosis, eh?
@@WollyFatboy Of course I cannot say for sure, but just thought it worth mentioning. Thing is it stopped when I stopped eating the salmon. There is a recommendation that you only eat fatty fish twice a week, so guess that is why.
I'm more worried about fish oil sitting on shelves for months and in warm conditions aiding its oxidation. I prefer to eat fresh salmon.
yup same here, that’s the main reason i stopped taking fish oil supplements. Instead i make sure to eat fresh salmon and sardines a few times a wekl
See headline: “Oh no! I have to stop taking fish oil supplements.”
Watch Ronda’s detailed analysis: “Naw, I’ll keep taking it.”
Thank you!
Men, find a woman that talks about you the way rhonda talks about fish oil.
if you take 4 grams or so according to the study, you might be. if you take 1-2 grams you still should be good. the study though like you have went through it is kind of flawed.
Correct me if I'm wrong but doesn't most research suggest that taking 1-2 grams is a complete and utter waste of money and that 3-4 grams of EPA is the minimal threshold to see significant health benefits?
@@AA-ki6zn not really. 2 grams of Fish Oil, Rhonda Patrick says later in the video raised people's Omega 3s from being below acceptable levels to normal. i measured mine and so far after reaching normal levels 1.5 grams was enough to keep up there at normal ranges. also 4 grams of fish oil is pretty costly on its own. most folks pick 2 grams just on that reason alone.
@@AA-ki6zn also check out this fish oil Physionic video on Fish Oil. ruclips.net/video/tX7xzzIhQgw/видео.html
I experienced heart palpitations and a few instances of afib when I took around 2g/daily. I was taking a triple strength supplement (1g) and if I ate salmon I had issues. I went to a lower dose supplement and I don't take it when I'm planning on having salmon on that day. I haven't had any issues since.
@@AA-ki6znlike vit d or many things, amounts pills consumed less important than blood levels eg vit d blood level or here omega index.
It's almost as if any time a compound or protocol has been in the news a lot recently for it's positive (or negative) outcomes - someone comes along and publishes something claiming the opposite during the peak of conversation around it.
Bingo
Actually being healthy is not profitable. You can smell the incoming bias on alot of these studies once you've read enough of them.
Yup
Anything seen to be benefitting the general populations health needs to be shut down!! The public must be protected for danger of getting healthy. Only processed foods and pharmaceuticals can truly benefit the general populous.
Just watched the video. Rhonda does an excellent job breaking down the weak basis for the reported conclusions. It must be very frustrating needing to regularly push back on these over dramatized "findings" that people don't dig into more thoughtfully.
Maybe we need to teach research methods more universally. We need much higher critical thinking skills.
I can confirm that I have arrhythmias if I have been ingesting 2g/day. It’s not placebo because I discover it before all these studies.
Right now, I’m switching to only DHA, let’s see how it goes.
Me ditto on that one! I've been a EPA DHA user for 10 years now and getting irregular heart beats. I think I have other issue going on but I did make the switch to higher DHA because I need it for my Brain. ALSO I saw another RUclips that talked about having more Omega 6 to balance and since I am almost 0 on the 6's I started using Borage Oil caps and that seems to help quite a lot! The theory is that on a cellular level there are 6's present more than the 3's so therefore the Imbalance. So the best 6's to take is Borage Oil due to the quality of fatty acid components. Anyway my heart is running much smoother now and I hope this serves as some help to someone.
Same for me. I tried for so long to find an alternative explanantiom but, finally i had to admit it was the omega3. Im down to 1g every other day with no issue
I think people should consider the very likely possibility that the quality of fish oil has significantly dropped in the last ten years. The economic crunch has gotten many companies to do less than ethical things to keep from going bankrupt. They had to choose between moral or economic bankruptcy.
Dr. Rhonda's exhortation about Omega 3's is solid. Keep enjoying fish and shellfish, seaweed, herbs - each in relative moderation. To paraphrase my father: '..living is dangerous..' He smoked, drank, did Valium before heart meds 😮.
Enough said.
I left boxing at age 28 because of suspected neurological reasons and since maybe 29 until now (37) I've been taking about 7g/day (total omega 3) daily from fish oil for the neurological effects not so much cardiovascular which I think are good and I haven't noticed any kind of Afib or anything negative at all. I know one person doesn't mean anything but I just thought I'd put that out there.
IDGAF what the "study" says... I 100% care who conducted the study, who paid for the study. The longest lived people IN THE WORLD eat TONS OF OMEGA3s...get TONS OF ALA...have the HEALTHIEST HEARTS
Are we talking about 2 grams overall (ie. 2 pills) or 2 grams of EPA / DHA... or combined EPA/DHA?
Personally with my anecdotal experience, I no longer take any fish oil in supplement form. I was taking a very high quality high EPA form and I developed AFib while on it. It's not worth the risk for me and I think that dietary intake of omega 3s is the much better and safer road to take.
Same here. I have A-Fib caused from fish oils. I know because I stopped taking them and my afib went away.
Endurance athletes have higher risk of AFib and at the same time lower mortality risk, including dying from stroke.
4:50 That means they might have health issues, trying to alleviate with supplements, therefore are willing to participate in the study.
Same was happening in the studies related to healthy dosage of alcohol, where control groups were overpopulated with chronically ill participants, drug users and former alcoholics. Once these individuals were removed from the analysis, the healthiest alcohol consumption turned out to be no consumption at all.
You and professor Huberman are so helpful and appreciated. Thank you ma’am! 🙏🏼
I better go to sprouts and get my ultimate omega even if my wallet is going to ache. I just don’t like the texture of fish and can’t find myself eating it.
It sounds like a horribly flawed study. Total self reporting?? No data on the participants actual health, no data on what kind of fish oil? Even still, the benefit from fish oil in general outweighs the small chance of A-fib. This is like arguing getting a Covid shot, the benefits (collectively) far outweigh the risks. Stupid. I hate reporting these days. I feel like my fish oil has helped reduce my triglycerides. Can you do a piece on the daily baby aspirin debate???
Not only that, and please go ahead and double check me on this, the data they have is pretty much from British patients voluntarily answering questions when they visit their General Practitioner (Primary care doctor), and it's more like they asked a bunch of people in 2005 "Do you take fish oil?", then every few years asked them the same question.
There is zero information about the quality of supplements, dose, or consistency.
Just a bunch of disjointed random sample points, poorly collected.
It's kind of mind boggling how a lot of medical professionals jumped on the wagon and started telling the public to stop taking omega-3 supplements based on such a laughably poor evidence.
Rhonda, do we know if the stain drug makers paid for this awful study?
Do you mean statins instead of stains?
My fishoil consumption were giving me weird heart beats that went away after 3-5 days of stopping consumption.
After seeing one of your old videos last year, one of your guests said that Omega3 fish oil was most beneficial if we were getting at least 1 gram of DHA and 1 gram of EPA per day, this meant I had to consume 6 grams of fish oil per day, because the capsules I had, only had 180mg DHA and 220mg EPA per capsules.
I do miss the other positive effects I got from taking the fish oil, like almost never brainfog and bone pains went away when taking omega3.
Omega Avail 2 capsules yields 800 mg of each. Designs for Health product. Expensive but will get you where you need to be
In my personal experience AFib has to do with low electrolytes from drinking a lot of water and taking a lot of supplements. Once i started taking an electrolyte tablet a couple times a day, I had no problem with AFib.
Hopefully the studies control for low electrolytes/dehydration before making conclusions.
What’s the manifestation of AFib?
@@thinkwhileeatingpasta5217 fast or irregular heartbeat. The most objective indication for me is a pulse rate that shoots up while at rest. Smart watches make it much easier to spot.
For those who are curious about the mechanism at play here: Low potassium (Hypokalemia) impairs the polarization of cardiac tissue which increases the risk of PACs (premature atrial complexes). This occurs even when potassium levels are sub-clinical and considered "low-normal" in blood tests. Too many PACs are a known trigger for afib so if you can reduce or prevent the PACs, you can reduce the chance of afib events.
The "study" did not take into account any of this. Even the use of "fish oil" was self-reported. It's about as weak a foundation as you can get.
To get a reliable result, you'd need to do double blind study and control, in a verifiable and repeatable way, for known confounding variables like potassium and preexisting hearts disease.
I wouldn't even call this report science.
Unfortunately, it will come back to you. Once you have a fib, it cannot be cured by electrolytes. But it can be effectively managed for a period of time until you can get surgery, the right type of surgery, to help eliminated. Unfortunately, a fib is progressive and can get very bad if not treated early.
Everybody talking about the omega 3 but forget about the magnesium link to a fib. Is there a study that shows high omega and nornal to high magnesium causes a fib?
I have afib, only fish oil supplements agitate it.
Magnesium 90% stopped my irregular heartbeats
I used to take 2 grams a day fish oil and had heart palpitations, maybe it was afib but it was a bit concearning every time it happened, its like your heart stops for a split second and then does like a double beat or something? Anyway I stopped taking them after I read that study a few months back and they went away! I take maybe 1 1000mg pill a week now.
They were ectopic beats
Primarily, I identify as a fish oil user. Secondarily, I identify as a man.
As a fellow health RUclipsr, I appreciate the insights shared in this video by Rhonda Patrick regarding the potential risks of fish oil supplements. It's crucial to approach such topics with a nuanced understanding, especially given the conflicting research surrounding omega-3 fatty acids.
One important aspect to consider is the type of omega-3s being consumed. EPA and DHA, the primary components found in fish oil, have been shown to have various cardiovascular benefits, including anti-inflammatory properties. However, the source of these omega-3s-whether from fish oil supplements or whole food sources like fatty fish-can significantly impact their effects on heart health.
Additionally, it's worth noting that individual responses to supplements can vary widely based on genetics, existing health conditions, and lifestyle factors. For instance, individuals with pre-existing cardiovascular issues may react differently to fish oil than those without such conditions.
Moreover, while the study mentioned in the video raises valid concerns, it's essential to look at the broader body of evidence. Many studies have indicated that omega-3 supplementation can lower triglyceride levels and may even reduce the risk of certain heart conditions when taken appropriately.
In conclusion, while it's wise to be cautious about supplement use, especially in light of new research, I believe that fish oil can still play a beneficial role in a balanced diet for many individuals. As always, consulting with a healthcare professional before making any significant changes to supplement intake is advisable. Thank you, Rhonda, for shedding light on this important topic!
I’m 35 and have had Afib since I was 12. I’m one of the only documented cases of its kind in the US. I can 100% confirm that fish oil supplementation increases Afib episodes significantly. The last thing you want as a someone with a heart condition is to voluntarily be inducing a potentially fatal arrhythmia. People with Afib should not be supplementing fish oil. More importantly, we need to figure out why this happens - it could imply something negative about the process or quality of the supplements, or it could also reveal something about the arrhythmia trigger. Eating large quantities of fish doesn’t have the same effect
Probably gut related. Or hiatal hernia related, mimicking symptoms of afib. Or chronic nutrient deficiency which also may lead back to gut and absorption.
@@MultiWeen Sorry this is just laughable. I’ve had 3 heart surgeries and am in case studies at Cleveland Clinic, Vanderbilt, and UPMC. No buddy, it’s not a mimic of Afib symptoms - it’s actually happening in real life. My lord lol what a ridiculous comment
@@rbt5785 Well laughter is the best medicine. You're welcome pal.
I've been in constant Afib for 8 years. Consuming herring and sardines doesn't effect me.
@@peterbedford2610 How would it trigger your Afib if you’re always in it already? Anyways, like I said, eating it doesn’t that the effect supplementation does, in any amount
I am 66 yrs. Diabetic and high BP. Having codliver oil for about 20 yrs. No problems
I struggled with heart palpitations for years finally identifying the cause from fish oil - the last thing I suspected. At .5g day, is the threshold that is ok for me. I don't care what the study says, it is a problem.
ROFL.. I HAD THREE ATTACKS.. I REALIZED IT WAS ON THE DAYS I HAD 2 EXPRESSO CAFÉ... I SINCE EVEN WHEN COLD TURKEY TO GET DEDRUGED FROM CAFFINE... SINCE I REMOVED ALL DRUGS AND SUGAR AND NO MORE COFFEE... HEART BEATS AT 50 TO 60.. Ps I use magnesio and potassio
Q: eats just 1 tablespoon of chia seeds (=2 gr of omegy-3) and 1 tablespoon of flaxseeds (=1,8 gr) that is almost 4 gr of omega-3 then, in addition to this, when one eats healthfully more omega-3 gets piled on top of that, and we are talking about a significantly (dangerously?) high dosage of omega-3 AND no omege-3 supplements have even been tabled. I am confused.
I've been taking 5 to 7 grams of fish oil for 15 years or more; no problems. I was taking 3 grams but noticed my inflammation went down considerably, i.e., following playing tennis, once I increased the amount (I am now 71). I rather suspect that, as per usual, it depends on individual physiology and risk factors.....though, as Rhonda has taken pains to emphasize here, the nay saying seems designed to frighten, and to steer people away from a patently healthy supplement. This goes hand in hand with all the other mainstream medical attempts to fear monger against everything from Vit. D to intermittent fasting (Remember the 'paper' that recently came out purporting to prove that IF increased mortality by 95%!!....Total, unmitigated nonsense and pro-Pharma propaganda). These amount to a concerted campaign by the usual suspects to denigrate truly beneficial - and often cheap, and usually highly effective - supplements or health strategies.
Anecdotally I believe this. Over a short period of time I had a couple of occurrences where during a zone 2 workout my heart rate jumped almost instantly from 130 to 210 BPM, stayed like that for a minute or two and then dropped back down. After reading that omega 3 supplementation could cause that, i dropped my dose in half to around 2 grams and it hasn't happened again in 2.5 years.
I take 12g fish oil per day and eat sardines daily with no afib. EPA/DHA intake is ~8g per day and I consume other omega 3 from plant sources as well
Question: What about me who was diagnosed with AFib, then had an ablation that removed the AFib symptoms. Do I face a renewed risk of Afib if I take 3g of fish oil a day? I understand that there are benefits towards the other health markers you mentioned, I'm just not keen on another increase in stroke risk. Regards W.
Is there any proposed mechanism on how fish oil disrupts the heart’s electrical system?
If this article relied on self reporting for whether subjects were taking fish oil, it makes me wonder how the authors determined who had A Fib. Was that from self reporting too?
At best, their metrics are imprecise and lack the rigor I would expect for such a bold claim.
0.05% of females find me attractive. Now those are numbers that tell me a lot🤣
What are free fatty acid, ethyl ester and try glyceride forms? I keep on hearing these terms but what are they? Which form is the liquid fish oil itself that you take in spoonfuls from a bottle and then the capsule form? I look on the bottles and packaging in the UK but cannot find these terms.
AFIB rates increased after Covid vaccines. Why take the risk taking fish oil if you have history or non history of Afib or arrhythmia
I like mussels, high in B12, and they seem to improve my sleep stats the night I have them. Perhaps that will fade with time as I keep eating them though? Easy for me to get as well in little tubs with good shelf life.
I believe it does cause it. I was taking it for years, but now I switched to cod liver oil and I notice a difference. 🤷♂️
Personally, when I take fish oil, my heart beat turns into a bucking broncho of bazaar arrhythmia.
I'm at 8.1% as of a week ago! Would you advise to maintain these levels to continue 2g/day of fish oil?
I’m confused. The risk reduction stats - are these all absolute or relative risk reductions?
Thank u for dunking on these clickbait claims dr p may they not RIP!!🙏💪
I got atrial fibrillation after taking 2grams of fish supplement for a year
Yep, that "research" is nothing more than a "sensational headline".
This is like saying people who go for a walk every day are at higher risk of spraining an ankle compared to people who stay in bed all day.
I wonder which drug company paid for their research?
I take flax seed oil rather than fish oil. Is that better?
Does full fish such as salmon or canned sardines increase risk?
Thanks so much for addressing this question!
Thank you Rhonda, Thanks to you I will continue to take Omega-3.
I wonder who financed the study...?
I took 10ml of cod liver oil for months until I had an event of atrial fibrillation. I know I might have genetic dispositions concerning overall heart health. I tried varying the dose and while I had another event after drinking a large amount of slightly salted water, I now reduced the overall intake by 1/3 and don't have problems any more.
It's most likely that for a specific cohorte the risk is much higher, though! Of course, if you average over total population, the relative risk shrinks drastically. But we need more data to confirm this.
Really helpful video. Thank you.
how would Americans call her accent? Californian? it's interesting.
Who cares. I'm Scottish.
Doesn’t seem to bother Eskimos.
I guess I'll take fish oil😂
It's true, it does cause afib at doses above 1gram a day.
Always get your fish oil from eating wild fish, and never supplements.
And what evidence are you basing that on?. None I take it.
@@ThePaulaon1 read the report she speaking of here. It states that exactly what I mentioned. And if if you don't believe the report, then you don't believe her, and you don't believe in science. In that case, nobody can help you.
I know 100% for sure fish oil supplements cause me to have ectopic beats...I never had afib and don't have afib but when I take 4 900mg capsules per day my heart skips beats and when I cut that down to 1 capsule per day it goes away within a week...I've tried this over and over again with the same results every time...I don't care what any study says I proved it personally and that's better than any study out there.
What a stupid question
Thank you Rhonda 😊
How about krill oil
From personal experience, I'm going to say yes.
Saying yes to what?
Thanks 👍
I get terrible insomnia from omega 3 supplements, doesn't matter what time of day I take them. It takes a few days after stopping to get restful sleep again. Anyone else experience this? And if so, anyone know a workaround?
Do you take other supplements, or medication? For 7 months, I have been trying to find the cause of my sleep problems (I wake up after 4-5 hours every night). I have been taking fish oil (in the morning) and other supplements. I have tried eliminating them one by one, but with no luck.
But some experts say that fish oil is beneficial for sleep😂
@@丁以 Some "experts" just do statistics.
@@Tommy_007 I take magnesium twice a day, which helps me sleep. Other than that I take no other supplements.
Why not just take flax seed and not worry about any fish oil risks?
Flax seed, chia seed, walnuts etc do not convert well to active Omega 3s in the body is what I have read so very little is absorbed.
That form like flax seed is in the form of ALA omega 3, this needs to be converted to epa and dha in the body. Fish oil is already is the form of epa and dha, it appears that ala converts very little to dha and epa, so I wouldn’t be relient on it for that reason. Still healthful foods that should still be included in your diet!
Flax seed contains only ALA which is one of the 3 fatty acids in omega 3. The other two are EPA and DHA.
The body can make EPA and DHA out of ALA but the conversion rate is very low.
And it gives your body more work to do.
If you’re looking for a vegan source you can find omega 3 oil capsules from algae.
Algae is the reason fish are high in omega 3 in the first place.
Small fish eat algae and then bigger fish eat the small fish transferring that omega 3
Now we are talking about unatural things like suppliments that have no regulation . It is processed and formulated . I eat a sliver of canned mackeral every day . I dont think the study diesnt cover natural form of onega .
Probably best to wtay away anything looking like a capsul or a pill. i am sure the membrane of the capsul is not great for you
🌟🌟🌟🌟🌟🌟🏆💛
Is getting omega-3 from chia and flax reasonable?
Chia seeds and flaxseed : How many time do we need to be told those are ALA/LA and have to be converted by the body to epa/dha It depends on how good your body is at converting. Keep eating chia and flax as they are great source of Ca, mg, fiber, D and protein - I’m sure you have read the label.
No, need the long chain omega 3 from fish oil
👍👍👍👍👍
I got AFib from 2g. I will keep dosing
Thank you for your knowledge and videos USA 🇺🇸 TRUMP
As I am the leading Vitamin D Deficiency Channel - I stop recommending fish oils - due to purity and them being a rancid oil !
Regarding “rancid”, take a look at the deep dive Physionic did on this and the research.
You’ll be very surprised if you are evidence based.
And were the participants vaccinated?
clowns who wrote the study still probably say "safe and effective".
Just another reason to take algae oil.
Algae oil wouldn’t be better if it’s purified EPA/DHA
