There didn't seem to be much chat about darker skinned people living further north. Also what happens when we have a poor summer, with little sunshine, relative to a better year?
My only gripe with Zoe is they quote scientific studies but fail to include them in the references or link followers to these studies. They also don't give enough information for followers to find these studies themselves. Give us details so we can read plz I get it that this is a podcast rather than a scientific essay or lab report but for those that are studying science or have already become a scientist it would be really valuable informstion, and it could also mean we coukd critique some of whats said on Zoe. Win win for everyone because we all learn, and Zoe is held to account for any possible shody experiments
Hey... my replies are not showing up... but to finally reply... Tim has been incorrect many times (search youtube 'calorie counting doesnt work' or 'exercise doesn't work', and see people explaining it). And he's always talking outside his field, you never know when he's wrong, and can often be.... hoping this comment goes through. :/ I prefer the episodes where the scientists are speaking about their field of study.
@martinbulmer1868 sadly most people are more pleased with themselves criticising than with really listening or looking into things. Zoe try really hard to give good advice. Of course this doesn't mean they know everything, or can always get the best of the best on the show. But I'd rather see their moderate content than the evangelising you see elsewhere. If people transcribed their content and then checked their criticism against it, they'd see much of it is a premeditated reaction to personalities or ideas they have a negative emotional response to, and not actually a valid argumentative response.
@@Raherin I guess it's cheaper than paying others. Plus if you listen, he does cite a lot of involvement in studies related to vit D. I can't imagine vit D specialists grow on trees. But, yes. It would always be better if they can find absolute specialists.

Science is a process. It is the best method of trying to understand the world. As we gather more evidence, the conclusions become firmer. You can choose not to believe in the scientific method, but any other form of understanding the world is infinitely worse. Tim himself stated that he is open to changing his mind on vitamin D if the evidence supports it. He is a mark of a good scientist. I myself have been taking 4000 IU of vit. D a day and after watching this video, I'm going to markedly reduce it. You might decide a different course or action. This here is the gray area, which science embraces.

I find that Tim Spector likes to find something which lots of other scientists/Doctors like and then trash it! I do watch these things and also have some of their books and found that each book has points in it that are different from the earlier ones and a genuine statement of “I got it wrong” however, your right how are we supposed to judge what’s right or wrong. Basically a little of everything and not too much of anything will probably do us all fine 🤔😃👍
These questions are very complex and there is ongoing research so probably no final definite answers to them yet. How else are we making any judgments if not based on actual scientific research?! Just opinions and/or manipulations for profit's sake.

The more I learn from Zoe and my app the more I understand living a natural life with good diet and little walk everyday day will just steer you well generally. Zoe has cured my IBS my poor sleep my poor mood and I enjoy food more. Thanks everyone at Zoe
Didn’t learn much here…. It’s pretty clear that high vit D ( 60-80 ng/ml) is not a health risk especially if vit K2 levels (microbiome or supp ) are normal..
Use Google's NotebookLM with the Audio Overview feature. It can turn audio, video (including youtube), and text sources into a 10 minute AI hosted podcast that is very convincing. Free feature.
Yes, if you are in a group that doesn't get enough sunlight (us night shift people included) or were specifically recommended to take vitamin D due to deficiency, then yes, you probably should supplement.
yes, Tim Spector seems not to know that it D is crucial in the metabolism of neurotransmitters., So, It does not matter if vit D causes mental health problems or not. What matters is that low vit D makes it more difficult for doctors like me to treat mental health problems.
Just tuned in and haven't finished watching this episode yet, but I have to comment about my own experience. I spend hours in the sun every day, I do not use sunscreen, and yet I am still severely deficient in vitamin D. Blood tests showed my levels of vitamin D were in the single digits. Perhaps I'm just part of that small minority that actually needs supplementation.
People with autoimune issues absorb vitamin D with problems. Like Hashimoto. I was told what others get in 20 minutes for a Hashimoto sufferer can take up to 8 hrs.
Quote the studies , which clinical studies are the zoe team quoting, where are they published? Which clinical trials re: vitamin d3 and k2, what exactly is being referenced or are we back to "expert opinion"?
Rather disillusioned by this podcast that might well put me off Zoe in the long run. So much more info about the beneficial effects of Vit D on the immune system out there with research to back it up especially with reference to flu, chest infections (apologies no link) and really, are we still banging on only about its effects on bones? That's so well known and documented and has been for many decades. Move on. Stick to the microbiome studies, Tim.
wouldn't it.....!? I think he wouldn't only be out of his lane but he'd get run over.... Dr Grimes was an actual practising clinician seeing real patients.
I quite agree. Dr Grimes also said older people or anyone with dry skin can’t convert Vit D from sunlight because they don’t produce the skin oil that’s required for the conversion. Dr Grimes recommended 1,000 IU’s per 10Kg body weight daily. He takes the equivalent of 8,000 IU’s daily in a single dose each week.
I take 10,000 IU per day as a maintenance dose along with Magnesium, Vitamin K2 and Zinc. Did you know if you sit out in the sun during the summer for 20 minutes your body generates 10,000 IU from the sun's rays. Some people spend hours in the sun, think how many IU's that will make. The NHS recommend people take no more than 400 IU a day. WHAT A JOKE.
THE NHS recommends 400 IU a day of Vitamin D which is a joke. If you go out in the sun for 20 minutes in the summer your body generates around 20,000 IU.
I am really surprised not to hear any mention of the fact that vitamin D3 needs vitamin K2 and magnesium in order to be able to process vitamin D supplements. I once spoke to a herbal nutritionist who made me promise to take a handful of greens (for the vitamin K2 element), in combination with the liquid vitamin D3 supplement. I know that I my health is very much better having worked outside in the sun than I do in the winter.
Tim Spector should call Dr. Anthony Fauci and educate him on why Vitamin D doesn't help with a certain respiratory disease. I think Federica was much more measured and scientific in her presentation. Spector has a completely closed mind on this. That's too bad.
Most people in the UK don't spend lots of time outdoors ... and even less on days when the sun is shining & they are "sporting lots of bare skin" ... most people will have covered skin, even on the few hot sunny days that the UK experiences
As for calcium, he should have explained that it's calcium CARBONATE that is bad to take since it's pretty much just ingesting rocks. The citrate form is way better, but never take more than a couple hundred mg's a day.
Tim keeps talking about fractures, most do not disagree on this. We should be focussing on the effects of supplementaion and the effetcs on the immune system. Particularly, studies when people are taking sufficient dosages and getting their blood levels up above a certain level.
I think this is an unsubtle episode. I would suggest you don't get sunburnt ever if you can help it. I would also suggest it's not possible to get sun exposure regularly in the UK especially if you have an indoor job (perhaps why we then go and get sunburnt it is sunny). I would recommend anyone with health issues takes vit d at the very least in the winter months especially if you start getting joint and muscle pain. Bear in mind that taking high doses of vit d could also lead joint and muscle problems. If you are well, have a good diet and are often outside then yes maybe you don't need a supplement. Skin cancer is still a thing. Last I heard there are more cases in the UK than Australia because we don't take it seriously.
Thank you for sharing this open discussion about para-hormone D! We need these conversations more than ever. There is so much controversy around supplementation. We have no idea what the “right” amount should be, we have no clear way of measuring it, and I believe that a very nuanced approach is needed for every individual. I couldn’t even take 200 IU without an inflammatory response in my hands after 2-3 days of taking it. My blood marker shows “low” 25-hydroxy level and I am completely healthy. Sun + food including lots of cooked mushrooms/greens/prunes give decent dose of calcium/K and D.
So they say 200-400 i.u. daily is ok, but they keep warning about "extremely high levels" can be "toxic" w/o defining *either*. What is an "extremely high level" of vitamin D? What does "toxicity" mean for excess vitamin D. Other than that, mostly common sense that could have taken less time. I agree sunlight is better than a pill (helps with infrared too, which I'm surprised they didn't mention), and we use too much sunscreen and we have been made to fear the sun when we should only fear sun*burn*. Calcium supplements are bad. And yes, genetic variation is huge. But i take 5000 i.u. a day with K2 and magnesium and see no reason to stop.
What may be missing is that these studies are taking Vitamin D on its own without co-factors. Can you read and comment on the vitamin D book Defend your Life. As it is the main book that explored Vitamin D.
Very interesting video. I do have a few comments though. 1. How is it possible that science has been recommending vitamin D supplements for decades and now suddenly no longer does? Wasn't the old science serious too? 2. Now I don't know whether or not you should take 400 IU in the winter in northern countries. 3. I don't know how long you should be outside in the winter to produce enough vitamin D. 4. I don't know how much skin should be exposed to the sun. 5. I don't know whether outdoor light is enough or whether the sun really has to shine.
Ridiculous 🤦♂️, in your previous episode w/ Professor JoAnn Manson she says… “I think at this point the evidence is really mounting that a multivitamin may be worth seriously considering just as a form of insurance and to hedge your bets. I would say the second would be a vitamin D supplement, 1000 to 2000 IU a day, a small to moderate dose, no mega dosing, not taking doses of 6,000, 10,000 IU a day, small to moderate dose. “
I would like them to explain how it is here in the United States that there are millions of people who work outside on a daily basis and are majorly deficient in vitamin D?
so it prevents MS and helps in inflammatory diseases like Chron's and cancer but only people in these sub groups should take it? Surely there is a continuum of benefit and therefore makes sense to supplement it if only as a potential preventative measure - agree that it is very complex but not convinced at all by the arguments here.
I found this interesting, but they didn't talk about the amount of skin that is exposed to sunshine, in the winter we tend to cover up, how does this affect fit D uptake?
Correct me if I am wrong, but I believe that not being water-soluble-and consequently not being “pee-able” in case of overdose and thus being able to cause hypervitaminosis-does not exclude a vitamin from being vitamin. There are other vitamins that are only fat-soluble: A, E, K. So whilst vitamin D may not be vitamin because our bodies can produce sufficient amounts of it (and thus it falls out from the definition of vitamin), its fat-solubility is only circumstantial to its (not) being vitamin.
People have to learn not to try and derive just true or false statements with nutrition and other science. Biology in particular is about homeostasis, which means there is a huge range of things to balance in a biological system - and not every person is exactly the same, even if there are general parameters and ranges to go by. So the answer isn't "vitamin D good"/"vitamin D bad" - the answer is it depends. Anyone not willing to spend time to figure out the nuances needs to find a trusted expert who can spend the time, ideally a trained medical professional (a doctor you know in real life and not just online influencers). Get second (and third...) opinions after that, which is what any trusted medical professional will also tell you is wise.
I was severely deplete of vitamin D and had lots of bad symptoms. Taking vitamin d has definitely helped me, first thing I’ve ever taken that I actually felt a difference. I’ll stick with it and can’t be bothered watching all of this video, too much conflicting info.
Also saying only take calcium if your doctor prescribes it - surely it would be better to advise some strong questioning of any GP routinely prescribing it for elderly patients as many GPs seem so ignorant of the risks of what they prescribe.
I'm at the 43rd parallel, so around the start of November I start taking a small amount, maybe 2-3000 units of D3 per week, ramping up thru the Winter. It's still a small amount compared to many.
Also I did Zoe for 6 months but developed an allergy to being patronised and spoken to as though I were a small dim child and recording all you eat on the terrible app is a full time job unless you fast which is maybe how so many people lose weight on it, they'd rather starve than go through the meal entry process
I was below the level in vit d showing up in a blood test my gp gave me a month's course of vit d I felt better in a matter of days.. my marker was 25 and should of been 75. My symptoms extremely tired even after a good night's sleep. I do have Photosensitivity which means I am allergic to Sunlight so when I do go out need to cover up head to foot so mot getting any sun on my skin hence why my vit d was low.
I have just listed to this and am more confused than ever. I take daily - 1000iu Vit D3 and a K2 to aid the absorption - having been aware that, as stated, 68% of the population in the U.K are deficient. Surely that means the sunlight and diets of these people is not giving sufficient Vit D, therefore a supplement is required. I was also confused that’s it wasn’t stored in the body.
Am I alone in thinking that the “thumbnail” headline title ZOE have chosen for this video (re Vit D) is “clickbait” that doesn’t really reflect the less dismissive content / nuanced conversation recorded?
Social media thumbnails tend to be like that, even from outlets not trying to be too clickbaity. Goes back even to traditional media headlines and ledes.
I respectfully disagree with their position. There are hundreds of research papers that demonstrate the benefits of Vitamin D supplementation. For these supplements to be effective and yield evidence-based results, the dosage must be appropriately tailored to each individual. This is likely the reason they believe it isn't effective.
It would be helpful if your experts told me upon what area of skin exposure they base their 15 minutes in the sun as being adequate. In winter I rarely wear short sleeves and, summer or winter, often wear a wide brimmed hat. What difference does that make? Summer direct sunlight and winter diffuse sunlight in cloudy conditions. Does that make any difference to their suggested time for adequate exposure? I take a 'vitamin' D supplement and have understood that it is stored by the body. What none of the experts tell me is whether there is any difference between taking 10 µg a day (the UK recommendation for winter) and 100 µg (10 days worth) weekly. Tim mentioned that D deficient groups were found to benefit from supplementation during Covid. How did they become deficient in the first place, please?
I get the feeling a lot of commenters aren't actually watching the whole podcast, but just taking things out of context without any of the nuances. The whole crux of the discussion here is that whole populations are being marketed and told that vitamin D is a wonder supplement when in reality there should be some level of caution and care in its use; nor should absolutely everyone be taking it, especially those who are healthy (no specific indicators or low vitamin D) and capable of synthesizing it from sunlight. Once you start taking vitamin (or hormone, in this case) supplements, you start having to consider proper balancing of what you are taking, as well as dosage. So yes, there are reasons to take it, for explicit deficiencies and immune health reasons, but I don't think it's wise to just start blanket recommending popping of vitamin D like its candy, despite it being OTC. The people who keep making "I'm done with Zoe!!!", "UNSUBSCRIBED" comments really need to learn how to examine a much wider range of evidence, in context, and using the scientific method. Don't just arrogantly assume you know everything from going down a youtube/tiktok influencer rabbithole, even if they are doctors or scientists.
I simply do not trust them because the imperative to sell Zoe seems to be paramount. In addition, a deficiency in vitamin D is measurable. Plus Vitamin D has been shown to reduce the dangerous effects of COVID.
Tim needs to explain how his claim of evolutionary advancement is supposed to have occurred. All organisms are coded with information at inception and there is no mechanism by which any can be added later. Mutations are errors that do not add any additional sequences but only drop or disrupt what is already there. The reason evolutionists cite Africa is only because that is where the chimps are that they claim humans evolved from
I do wonder what "commercial; concerns" have been "driving" interest in vitamin D. Anyone can make it and it doesn't cost much, so I wonder how much profit any one company can make.
The only commercial concerns here are Spector with his grift with gut health products - which often amounts to good old fashioned common sense dressed up as cutting edge science.
Have the Drs. seen the randomised trail with Vit D supplements - where there was a serious reduction in auto immune diseases? Also look into NIR which D is a marker for.
If you live in a sunny Southern Hemisphere country and spend a lot of time out of doors then can you get too much Vitamin D just from the effect of the sun on your skin?
No, the body regulates Vitamin D production when it's induced by sunlight exposure. Obviously you dont want to spend too much time in direct sunlight (unprotected) for UV and sunburn risks, but spending time outdoors isnt going to lead to excess vitamin D levels.
None of these comments really address the risk of taking 4000 iu of D3. The actual benefit of D3 levels is dynamic because instantaneous health status determines how much is beneficial now.
I would like to know if there has ever been a study showing the effect of taking supplemental vitamin D on the measured level of vitamin D in the bloodstream. Does it reach a plateau? Is mist of the excess excreted?
Any link with vitamin D3 supplementation and anxiety? I had to stop due to overwhelming anxiety on three different times. It is enough to stop treatment with the D3 supplement. My vitamin D levels have been historically 25 to 30. (40-year-old male). I have not checked my vitamin K2 levels at this point I am just getting negligible sunlight.
Taking mega doses of vitamin D has become popular since the start of the COVID pandemic when the FLCCC and later, disgraced former nurse John Campbell started to recommend it on RUclips. For what it’s worth, I’d go by Tim’s recommendations.
Disgraced former nurse John Campbell? Who says so? He's a man of integrity and has ridiculed "quite rightly" big pharma many times and has many followers 😮
It may be worth remembering that our ancestors on these islands managed to live and prosper for many thousands of years without taking Vitamin D supplements.
@@jdavies7472 excuses and the convenience of working from a home office or in buildings. Just go outside for 15 minutes and expose some bare skin to the sun. You don't have to live like our ancestors.
If everybody would have at least a level of 50ng/ml and keep an eye on the cofactors - Mg, K2, A, C, Boron a lot of GP etc. would see very few clients especially in the wintermonth ...

I am a Zoe member and wish I had more time to watch the Zoe podcasts: they are always good. I have a calcium question: is calcium in water, for instance, generously present in North London's water, usable in the same way by the body as calcium in dairy products or supplements? Or is it such a different form of calcium and with an entirely different effect in a body's metabolism, that it doesn't come into the consideration of calcium ingestion? Is London water good for an elderly woman or bad?
You can count calcium in water towards daily calcium but it is not the same form as calcium in milk (yoghurt/kefir better than milk for calcium absorption)
Biotin (B7) is the only one I'm aware of that can be produced in the body (bacteria in the intestines). I don't think that's even in sufficient quantities to be considered "non-essential", though, you still need to get it from food.
Honestly, why does Tim Spector (as a scientist) go so far outside his field? He's been caught saying wrong things all the time by actual people who's field is things Tim talks about. Also, why is he a guest ON HIS OWN CHANNEL? Also, why does it matter if he's 'top cited scientist'. Seriously tired of this guy and his desire to be a health guru, like so many others. Done with this channel.
I hear you, but I believe it would be better if you actually provided constructive criticism or pointed out what he got wrong. I'm genuinly intrigued by what your thoughts are (I might learn something myself)
@@po72644 You can find lots of people debunking Tim on youtube, I'm not a scientist, nor could I go in depth on why they are wrong, but that's why I let people who are experts IN THE FIELD debunk Tim Spector, for example, he said exercise doesn't work, or calorie counting doesn't work (surprise, it's one of the few things that DOES actually work.). You'd think some of these things would make him stop and think, but I think Tim's ego is getting the better of him. And it's not that I think he's wrong in this video.. I just can never tell if he's wrong or not (like any heath 'guru' on youtube), and he talks about so many different expertise outside his field. Why not just stick to epidemiology? Why not just have specialized guests for those things? He's been a recurring guest on his OWN SHOW for years talking OUTSIDE HIS FIELD more than he talks INSIDE his field. He's using epidemiology as a gateway into other fields, just like chiropractors do (Eric Berg, Joe Dispensa)

I was taking high dose Vitamin D plus Vitamin K for a while back in 2021/22 and eventually ended up in hospital with something called Hypercalcemia (too much calcium in the blood). Had to stop taking the supplements but then a couple of months after that, I got diagnosed with Stage 4 non hodgkins Lymphoma. Went through treatment and now in remission for 2 years. Don't know if there was any link between the two but the vit d+k went in the bin
@@stevelanghorn1407 Yes, meant Hypercalcemia (the spell checker done that lol). It one horrible condition to have and only showed up on blood tests as blood calcium levels going through the roof. Could have been coincidental but could never get a consensus from the various doctors and consultants that I was and am still under.
@@jerseytony1 I was taking Vitamin D3 5000IU and K2 MK-7 200mcg and after about a month of taking them daily, I got taken into hospital with the Hypercalcemia.
Why are these people talking about stuff they don't know the answers to. This is something Tim does all the time and has been known to flip-flop throughout his career so why should we believe anything he says and to be honest they simply don't know the answer to these questions they are just guessing.
The chances of going to a Doctor and getting a check of vitamim D levels is near zero. As it is relatively cheap then easier just to have a daily dose. It doesn't half take a long time for the team to come out with the useful bits.
Wot? Dr John Campbell has spoken at length about the uses and need for vit D and you are now telling me it's putting my health at risk? Come on guys. I expect my health gurus to be on the same page...
There didn't seem to be much chat about darker skinned people living further north. Also what happens when we have a poor summer, with little sunshine, relative to a better year?
Surprised they didn’t talk about Vitamin D with K2 and effects. Very popular combination.

How did it cure your IBS, if you dont mind me asking? What have you changed and what were you doing prior?
Didn’t learn much here…. It’s pretty clear that high vit D ( 60-80 ng/ml) is not a health risk especially if vit K2 levels (microbiome or supp ) are normal..
For goodness sake, why does this have to take over an hour? Please can we have a few simple takeaways!

I stopped watched Zoe ages ago because of all the waffle and padded out chat about bollocks.
Intoxication with D is pretty difficult
Indeed. There is very little evidence of it happening.
Ooh i find it very intoxicating....
I’m a nurse. Our own doctors recommend we take vit d supplements cos we do long shifts indoors and don’t get sun
Exactly! I would have thought it was important for people who work permanent nightshifts too.
Yes, if you are in a group that doesn't get enough sunlight (us night shift people included) or were specifically recommended to take vitamin D due to deficiency, then yes, you probably should supplement.
The NHS only recommends 10mcgs (or 400 IUs) a day, tho.
I took vitamin d and it stopped my low mood straight away. My health is not great. So i know i need to keep taking it. Fact.
yes, Tim Spector seems not to know that it D is crucial in the metabolism of neurotransmitters., So, It does not matter if vit D causes mental health problems or not. What matters is that low vit D makes it more difficult for doctors like me to treat mental health problems.
Just tuned in and haven't finished watching this episode yet, but I have to comment about my own experience. I spend hours in the sun every day, I do not use sunscreen, and yet I am still severely deficient in vitamin D. Blood tests showed my levels of vitamin D were in the single digits. Perhaps I'm just part of that small minority that actually needs supplementation.
As you age, the body is not able to synthesise it as well from sunlight
People with autoimune issues absorb vitamin D with problems. Like Hashimoto. I was told what others get in 20 minutes for a Hashimoto sufferer can take up to 8 hrs.
The body makes less as we get old, Other experts in the field call it a hormone.
What about the severity of COVID infection in elderly people being worse in those with low level Vit D?
Lots of stuff I don't really agree with here, but I love that she said for some people going out in the sun WITHOUT SUNSCREEN is a GOOD thing.
Quote the studies , which clinical studies are the zoe team quoting, where are they published? Which clinical trials re: vitamin d3 and k2, what exactly is being referenced or are we back to "expert opinion"?
There are reference to the studies in the intro, right near the bottom, so needs a long scroll down.
Rather disillusioned by this podcast that might well put me off Zoe in the long run. So much more info about the beneficial effects of Vit D on the immune system out there with research to back it up especially with reference to flu, chest infections (apologies no link) and really, are we still banging on only about its effects on bones? That's so well known and documented and has been for many decades. Move on. Stick to the microbiome studies, Tim.
I don't think the evidence is strong enough to claim the infection benefits yet, we only have correlational studies and uncontrolled case studies
What really would be interesting? A discussion between dr. Spector and drs. David Anderson and David Grimes!
wouldn't it.....!? I think he wouldn't only be out of his lane but he'd get run over.... Dr Grimes was an actual practising clinician seeing real patients.
I quite agree. Dr Grimes also said older people or anyone with dry skin can’t convert Vit D from sunlight because they don’t produce the skin oil that’s required for the conversion. Dr Grimes recommended 1,000 IU’s per 10Kg body weight daily. He takes the equivalent of 8,000 IU’s daily in a single dose each week.
It's well known that the NHS recommendations on Vit-D are woefully low. The upper safe limit for daily vitamin D intake for most adults is 4,000 IU
the NHS lets people down on multiple fronts. Nothing new here
I take 10,000 IU per day as a maintenance dose along with Magnesium, Vitamin K2 and Zinc. Did you know if you sit out in the sun during the summer for 20 minutes your body generates 10,000 IU from the sun's rays. Some people spend hours in the sun, think how many IU's that will make. The NHS recommend people take no more than 400 IU a day. WHAT A JOKE.
THE NHS recommends 400 IU a day of Vitamin D which is a joke. If you go out in the sun for 20 minutes in the summer your body generates around 20,000 IU.
I am really surprised not to hear any mention of the fact that vitamin D3 needs vitamin K2 and magnesium in order to be able to process vitamin D supplements. I once spoke to a herbal nutritionist who made me promise to take a handful of greens (for the vitamin K2 element), in combination with the liquid vitamin D3 supplement. I know that I my health is very much better having worked outside in the sun than I do in the winter.
Tim Spector should call Dr. Anthony Fauci and educate him on why Vitamin D doesn't help with a certain respiratory disease. I think Federica was much more measured and scientific in her presentation. Spector has a completely closed mind on this. That's too bad.
Most people in the UK don't spend lots of time outdoors ... and even less on days when the sun is shining & they are "sporting lots of bare skin"
... most people will have covered skin, even on the few hot sunny days that the UK experiences
Test your 25OHD levels and supplement accordingly. Not complicated or controversial
Nowadays we spend 95% of time indoors in general. If we go outside how much of our body is exposed. Not much, if it is we pour sunscreen all over it
To be fair Spector did recently say that wearing sunscreen was wrong - and he got piled on by the whole science community 😂
As for calcium, he should have explained that it's calcium CARBONATE that is bad to take since it's pretty much just ingesting rocks. The citrate form is way better, but never take more than a couple hundred mg's a day.
Tim keeps talking about fractures, most do not disagree on this. We should be focussing on the effects of supplementaion and the effetcs on the immune system. Particularly, studies when people are taking sufficient dosages and getting their blood levels up above a certain level.
I think this is an unsubtle episode.
I would suggest you don't get sunburnt ever if you can help it.
I would also suggest it's not possible to get sun exposure regularly in the UK especially if you have an indoor job (perhaps why we then go and get sunburnt it is sunny).
I would recommend anyone with health issues takes vit d at the very least in the winter months especially if you start getting joint and muscle pain. Bear in mind that taking high doses of vit d could also lead joint and muscle problems.
If you are well, have a good diet and are often outside then yes maybe you don't need a supplement.
Skin cancer is still a thing. Last I heard there are more cases in the UK than Australia because we don't take it seriously.
What about fighting disease? Suggested that for every molecule of infection one molecule of "vitamin" D is destroyed?
Thank you for sharing this open discussion about para-hormone D! We need these conversations more than ever.
There is so much controversy around supplementation.
We have no idea what the “right” amount should be, we have no clear way of measuring it, and I believe that a very nuanced approach is needed for every individual.
I couldn’t even take 200 IU without an inflammatory response in my hands after 2-3 days of taking it. My blood marker shows “low” 25-hydroxy level and I am completely healthy.
Sun + food including lots of cooked mushrooms/greens/prunes give decent dose of calcium/K and D.
So they say 200-400 i.u. daily is ok, but they keep warning about "extremely high levels" can be "toxic" w/o defining *either*. What is an "extremely high level" of vitamin D? What does "toxicity" mean for excess vitamin D.
Other than that, mostly common sense that could have taken less time. I agree sunlight is better than a pill (helps with infrared too, which I'm surprised they didn't mention), and we use too much sunscreen and we have been made to fear the sun when we should only fear sun*burn*. Calcium supplements are bad. And yes, genetic variation is huge. But i take 5000 i.u. a day with K2 and magnesium and see no reason to stop.
What may be missing is that these studies are taking Vitamin D on its own without co-factors. Can you read and comment on the vitamin D book Defend your Life. As it is the main book that explored Vitamin D.
Exactly. Unfortunately scientists and medics receive no training in formal logic, thus so many false conclusions.
Very interesting video. I do have a few comments though. 1. How is it possible that science has been recommending vitamin D supplements for decades and now suddenly no longer does? Wasn't the old science serious too? 2. Now I don't know whether or not you should take 400 IU in the winter in northern countries. 3. I don't know how long you should be outside in the winter to produce enough vitamin D. 4. I don't know how much skin should be exposed to the sun. 5. I don't know whether outdoor light is enough or whether the sun really has to shine.
Interesting, your call-out to subscribe to this channel is almost identical to the one of "The Diary of A CEO" 😅
I need it for my bone health D+ K3 and K1+K2 and I take it.
Words without numbers is BS.
Also, what about the alleged ability to synthesize reduces with those less young?
Ridiculous 🤦♂️, in your previous episode w/ Professor JoAnn Manson she says…
“I think at this point the evidence is really mounting that a multivitamin may be worth seriously considering just as a form of insurance and to hedge your bets.
I would say the second would be a vitamin D supplement, 1000 to 2000 IU a day, a small to moderate dose, no mega dosing, not taking doses of 6,000, 10,000 IU a day, small to moderate dose. “
Dr Federica has a lovely voice
She has a lovely everything.

Correct, but doesn't mean anything for the topics being discussed
@@smedleybelkin19 IBTC
I would like them to explain how it is here in the United States that there are millions of people who work outside on a daily basis and are majorly deficient in vitamin D?
so it prevents MS and helps in inflammatory diseases like Chron's and cancer but only people in these sub groups should take it? Surely there is a continuum of benefit and therefore makes sense to supplement it if only as a potential preventative measure - agree that it is very complex but not convinced at all by the arguments here.
Just expose yourself to sunlight for 15 minutes
In Europe - it's october and going into the winter months = no sunlight...
I found this interesting, but they didn't talk about the amount of skin that is exposed to sunshine, in the winter we tend to cover up, how does this affect fit D uptake?
Correct me if I am wrong, but I believe that not being water-soluble-and consequently not being “pee-able” in case of overdose and thus being able to cause hypervitaminosis-does not exclude a vitamin from being vitamin. There are other vitamins that are only fat-soluble: A, E, K. So whilst vitamin D may not be vitamin because our bodies can produce sufficient amounts of it (and thus it falls out from the definition of vitamin), its fat-solubility is only circumstantial to its (not) being vitamin.
I'm so fed up with all the contradictions. Does anyone know the truth?
Your body does. ..keep listening to it
People have to learn not to try and derive just true or false statements with nutrition and other science. Biology in particular is about homeostasis, which means there is a huge range of things to balance in a biological system - and not every person is exactly the same, even if there are general parameters and ranges to go by. So the answer isn't "vitamin D good"/"vitamin D bad" - the answer is it depends.
Anyone not willing to spend time to figure out the nuances needs to find a trusted expert who can spend the time, ideally a trained medical professional (a doctor you know in real life and not just online influencers). Get second (and third...) opinions after that, which is what any trusted medical professional will also tell you is wise.
What if you live in a hot climate like I do? I stay out the sun like most people here.
Just go out in the sun for about 20-30 minutes and you will get plenty of Vitamin D. Just make sure you don't burn.
Just go out in the sun for about 20 minutes and you will get plenty of Vitamin D. Just make sure you don't burn which is important.
again nothing learned im still hoping and wasting hours watching this
incredibly shallow look at the topic
I was severely deplete of vitamin D and had lots of bad symptoms. Taking vitamin d has definitely helped me, first thing I’ve ever taken that I actually felt a difference. I’ll stick with it and can’t be bothered watching all of this video, too much conflicting info.
Also saying only take calcium if your doctor prescribes it - surely it would be better to advise some strong questioning of any GP routinely prescribing it for elderly patients as many GPs seem so ignorant of the risks of what they prescribe.
I'm at the 43rd parallel, so around the start of November I start taking a small amount, maybe 2-3000 units of D3 per week, ramping up thru the Winter. It's still a small amount compared to many.
Also I did Zoe for 6 months but developed an allergy to being patronised and spoken to as though I were a small dim child and recording all you eat on the terrible app is a full time job unless you fast which is maybe how so many people lose weight on it, they'd rather starve than go through the meal entry process
Vitamin D supplements taken Orally take 20 days for the liver to process
Make the clear water muddy! Nice try!
I was below the level in vit d showing up in a blood test my gp gave me a month's course of vit d I felt better in a matter of days.. my marker was 25 and should of been 75. My symptoms extremely tired even after a good night's sleep. I do have Photosensitivity which means I am allergic to Sunlight so when I do go out need to cover up head to foot so mot getting any sun on my skin hence why my vit d was low.
Yet again, Spector stepping out of his lane.
I have just listed to this and am more confused than ever. I take daily - 1000iu Vit D3 and a K2 to aid the absorption - having been aware that, as stated, 68% of the population in the U.K are deficient. Surely that means the sunlight and diets of these people is not giving sufficient Vit D, therefore a supplement is required. I was also confused that’s it wasn’t stored in the body.
Didn’t hear much evidence of overdose.
Am I alone in thinking that the “thumbnail” headline title ZOE have chosen for this video (re Vit D) is “clickbait” that doesn’t really reflect the less dismissive content / nuanced conversation recorded?
Social media thumbnails tend to be like that, even from outlets not trying to be too clickbaity. Goes back even to traditional media headlines and ledes.
I respectfully disagree with their position. There are hundreds of research papers that demonstrate the benefits of Vitamin D supplementation. For these supplements to be effective and yield evidence-based results, the dosage must be appropriately tailored to each individual. This is likely the reason they believe it isn't effective.
It would be helpful if your experts told me upon what area of skin exposure they base their 15 minutes in the sun as being adequate. In winter I rarely wear short sleeves and, summer or winter, often wear a wide brimmed hat. What difference does that make? Summer direct sunlight and winter diffuse sunlight in cloudy conditions. Does that make any difference to their suggested time for adequate exposure?
I take a 'vitamin' D supplement and have understood that it is stored by the body. What none of the experts tell me is whether there is any difference between taking 10 µg a day (the UK recommendation for winter) and 100 µg (10 days worth) weekly.
Tim mentioned that D deficient groups were found to benefit from supplementation during Covid. How did they become deficient in the first place, please?
I get the feeling a lot of commenters aren't actually watching the whole podcast, but just taking things out of context without any of the nuances.
The whole crux of the discussion here is that whole populations are being marketed and told that vitamin D is a wonder supplement when in reality there should be some level of caution and care in its use; nor should absolutely everyone be taking it, especially those who are healthy (no specific indicators or low vitamin D) and capable of synthesizing it from sunlight.
Once you start taking vitamin (or hormone, in this case) supplements, you start having to consider proper balancing of what you are taking, as well as dosage. So yes, there are reasons to take it, for explicit deficiencies and immune health reasons, but I don't think it's wise to just start blanket recommending popping of vitamin D like its candy, despite it being OTC.
The people who keep making "I'm done with Zoe!!!", "UNSUBSCRIBED" comments really need to learn how to examine a much wider range of evidence, in context, and using the scientific method. Don't just arrogantly assume you know everything from going down a youtube/tiktok influencer rabbithole, even if they are doctors or scientists.
I simply do not trust them because the imperative to sell Zoe seems to be paramount. In addition, a deficiency in vitamin D is measurable. Plus Vitamin D has been shown to reduce the dangerous effects of COVID.
Tim needs to explain how his claim of evolutionary advancement is supposed to have occurred. All organisms are coded with information at inception and there is no mechanism by which any can be added later. Mutations are errors that do not add any additional sequences but only drop or disrupt what is already there.
The reason evolutionists cite Africa is only because that is where the chimps are that they claim humans evolved from
Very interesting and useful information, thank you.
I do wonder what "commercial; concerns" have been "driving" interest in vitamin D. Anyone can make it and it doesn't cost much, so I wonder how much profit any one company can make.
The only commercial concerns here are Spector with his grift with gut health products - which often amounts to good old fashioned common sense dressed up as cutting edge science.
My sister, 4 years my senior, tells me I was taken to a clinic for UV treatment for ricketts.
Have the Drs. seen the randomised trail with Vit D supplements - where there was a serious reduction in auto immune diseases? Also look into NIR which D is a marker for.
If you live in a sunny Southern Hemisphere country and spend a lot of time out of doors then can you get too much Vitamin D just from the effect of the sun on your skin?
No, the body regulates Vitamin D production when it's induced by sunlight exposure. Obviously you dont want to spend too much time in direct sunlight (unprotected) for UV and sunburn risks, but spending time outdoors isnt going to lead to excess vitamin D levels.
old people have wrinkled skin so even if they expose themselves to the sun their skin has reduced efficiency to absorb it.
None of these comments really address the risk of taking 4000 iu of D3. The actual benefit of D3 levels is dynamic because instantaneous health status determines how much is beneficial now.
I would like to know if there has ever been a study showing the effect of taking supplemental vitamin D on the measured level of vitamin D in the bloodstream. Does it reach a plateau? Is mist of the excess excreted?
Be sceptical about anything you see on RUclips !
Any link with vitamin D3 supplementation and anxiety?
I had to stop due to overwhelming anxiety on three different times. It is enough to stop treatment with the D3 supplement.
My vitamin D levels have been historically 25 to 30. (40-year-old male).
I have not checked my vitamin K2 levels at this point I am just getting negligible sunlight.
Taking mega doses of vitamin D has become popular since the start of the COVID pandemic when the FLCCC and later, disgraced former nurse John Campbell started to recommend it on RUclips. For what it’s worth, I’d go by Tim’s recommendations.
Tim’s as controversial as Campbell. Lots of scientists and health experts think Spector is a grifter. Be careful.
Disgraced former nurse John Campbell? Who says so? He's a man of integrity and has ridiculed "quite rightly" big pharma many times and has many followers 😮
Not sure why you have the impression that John Campbell is disgraced.

It may be worth remembering that our ancestors on these islands managed to live and prosper for many thousands of years without taking Vitamin D supplements.
Because they were outside often and probably ate more real foods. We do not do that as a collective.
@@dh6320 and they were shorter.

If everybody would have at least a level of 50ng/ml and keep an eye on the cofactors - Mg, K2, A, C, Boron a lot of GP etc. would see very few clients especially in the wintermonth ...

I vary between 50 and 125ng/ml ... who tells us it is not helpful didn't get the concept .. we guess what is behind ... the problem is not the too much it is the too low ..

What I want to know is supplementing with vitd3 without calcium bad for the heart?
I am a Zoe member and wish I had more time to watch the Zoe podcasts: they are always good. I have a calcium question: is calcium in water, for instance, generously present in North London's water, usable in the same way by the body as calcium in dairy products or supplements? Or is it such a different form of calcium and with an entirely different effect in a body's metabolism, that it doesn't come into the consideration of calcium ingestion? Is London water good for an elderly woman or bad?
You can count calcium in water towards daily calcium but it is not the same form as calcium in milk (yoghurt/kefir better than milk for calcium absorption)
Just thinking,how about a person with agoraphobia who doesn’t go out
Cue the salespeople :-)
What about needing more during (peri)menopause because you absorb less of it?
I disagree you need d3 about 2-5000 iu woth k2 and magnesium
if receptors are cellular and sun makes us convert D Should we add D t our skin? or Infrared light?
MS is also high in South Africa.
I thought the body made the B vitamins?
Biotin (B7) is the only one I'm aware of that can be produced in the body (bacteria in the intestines). I don't think that's even in sufficient quantities to be considered "non-essential", though, you still need to get it from food.
What is cons8dered to be an optimal Vit D blood level? About to start a multi vitamin that includes 200 mg of calcium. Is this cause for concern?
Honestly, why does Tim Spector (as a scientist) go so far outside his field? He's been caught saying wrong things all the time by actual people who's field is things Tim talks about. Also, why is he a guest ON HIS OWN CHANNEL? Also, why does it matter if he's 'top cited scientist'. Seriously tired of this guy and his desire to be a health guru, like so many others. Done with this channel.

Had to stop taking the supplements but then a couple of months after that, I got diagnosed with Stage 4 non hodgkins Lymphoma. Went through treatment and now in remission for 2 years.
