Can vitamin D help fight diseases such as cancer?
Jonathan talks with Professor JoAnn Manson to try and find out.
Professor JoAnn Manson is a professor of epidemiology at the Harvard School of Public Health and one of the world's most cited researchers. She’s run multiple enormous studies, with over 20,000 participants, to uncover the real effects of vitamin supplementation on our health.
Dr. Sarah Berry is one of the world's leading experts on human nutrition. She has run more than 20 randomized clinical trials looking at how humans respond to different fats.

I'm surprised about the fracture results. Did they test Vitamin D3 with K2 for the older people concerning fractures, or just the D3? There is far too much scaremongering amount toxic levels of Vit D from supplementation. It's very difficult to get toxic levels for the vast majority of the population, (you'd probably have to misplace a decimal point) and if you are at all worried, just get a blood test done, they are not expensive (in the UK at least). We get only 5 months of Sun at a high enough angle to produce Vit D in the skin here, and any reserves built up are depleted way before the remaining 7 months are over. Vitamin D has a half life of around 15 days, so it only takes a couple of months to be down to less than 10% of what you had at the end of Summer, so certainly by the middle of the Winter here, people are probably at their lowest levels of Vitamin D of the year, and are so for another 3-4 months. The effects of Winter colds/flu and SAD would all be reduced if 70% of the UK population weren't deficient over Winter.
Supplemental is good especially autumn -spring. Regarding the vit d3, I use to work for pharma company promoting it to docs for osteoporosis. All discredited now in preventing osteoporosis. Weight bearing exercise seems the best way to prevent. I also have sad and vit D effect was there but minimal. Relying on tablets for all conditions is going out the window. Need other therapies mixed in, CBT, physical activity etc CBT
Good points. I need to watch the hour long video. Hard for me to imagine these Vit D/bone studies were done just measuring Vit D intake versus Vit. D blood levels. Some people can take 5,000 IU daily and struggle getting levels above 40 while others can get by with 500 IU daily and maintain levels above 60, no matter where the climate. Hope they give links to the actual research studies Manson refers to. Perhaps I wasn't paying good enough attention when she talked about it here.
@@jonathanperry4189vitamin D for SAD I'm sure is, as you say, just one part of a whole spectrum of things that provide benefit - exercise, balanced meals, etc. but I feel pretty sure vitamin D being called 'the sunshine vitamin' (for obvious reasons) is a simplification people latch onto. This might mean they place slightly less importance on trying to get vit D naturally and therefore might miss out on the other benefits of sunlight - mainly IR. IR light has been looked at for it's effects at helping people fight covid. I wish people would get outside and exercise - it would help them so much. Any time of year.
@@lanettescapillato714 The most abused words in science or politics is “can” and “some”. Ultimately yes every person needs an individual assessment, however that’s not happening. There is nothing wrong with telling people to take 5000 iu of D3. K2-M7 is good too and harmless.
Vitamin D receptor polymorphisms (Genetics) may produce continuing rampant inflammation in a person who has "normal" D3 levels. Liposomal D3/K2 is in the marketplace and it seems to work wonders for those who have absorption/metabolization issues due to whatever reason(s).
To clarify, fish do not synthesize their own EPA and DHA. They consume marine algae that synthesize it. The EPA and DHA in the marine algae sourced supplements are the same chemical compounds found in fish oil. This is in contrast to the terrestrial plant sourced ALA. All of the benefits attributed to marine EPA and DHA are present in the supplements sourced from marine algae. The concern about fish oil is contamination with heavy metals and other pollutants that concentrate in fish. Algae sourced EPA and DHA have much lower risk of exposure to toxic pollutants.
Good to know, thanks :)
Very disappointing. I will have to watch the full episode but so far I fail to see the need for caution. Vitamin D is very safe and while the jury is out it could do no harm at all for people to take it and more likely, a lot of good. The Professor even said that Vitamin D "is SO essential for health". Incidental sun exposure doesn't cut it. We don't get nearly enough sunny days in the UK to build up good levels.
I am aware of medics reporting recent increase in cancer progression, possibly associated with spike protein in both covid virus and mRNA vaccine compromising T cell immune response - cancer severity related to vitamin D serum level. Vitamin D toxicity is rare, but deficiency is widespread among the population, particularly in the obese and dark-skinned cohorts. Vitamin D is fat soluble, works with K2 and magnesium to minimise soft tissue calcification.
Also helpful for chronic uti.
The question is - does the Dr take Vit D supplements given her knowledge of the research, and if so how much? And does she also take K2 to ensure the calcium goes to the bones and not arteries.
@4min on incidental sun exposure. I would say test, supplement, and repeat until you get dialed in. In my early 60s living in Florida and walking outside daily (5 miles plus) my D levels were a little under 30 ng/ml (US units which represents lowest end of ref, range). Sitting in the sun 10 15 minutes a day extra with most of my body exposed didn't make much of a difference, a few ng/ml which could have been data scatter. After multiple D3 supplement regimes (starting with 1,000 IU) and repeated testing, I settled on about 4,000 IU/d D3 to get my level up to low 40 ng/ml. So test, and base supplements on test results. I have been consistently in 40 to 50 ng/ml range now for years of taking 4,000 to 5,000 IU per day most days (plus Florida sun exposure). Keep in mind that evolutionarily, homo sapiens got a lot more sun exposure over hundreds of thousands of years than in the last century in the 1st world societies where we are basically indoor creatures.
I've settled in at 6000 I.U. per day in recent months. But I live in Canada. I don't bother with testing.
I have MS. Vit D helps me sleep, and makes me feel a lot better. I don't know about the research. Anecdotes for the win!
Have A Look at grassroots Health,Nonprofit Informations about Vitamin D.With MS also have a Look at COIMBRA Protokoll.
I've been taking fish oil based Omega 3 daily for the last 17 years and 4000ius of Vit D3 daily for the last 4 years. And I will carry on taking them unless someone says 'stop'. Certainly my GP is happy with what I'm doing.
My prostate cancer appears to be in remission. (I'm 81.). Take VD & eat Salmon. But the main difference to my diet over the period of remission so far is adding to my lemon teas by sliced lemn with boiling water as my regular drink. No scientific evidence but i feel healthier and there is the remission. In particular I make a boiling lemon drink drink in the evening that have it next morning. Feels great but as said...... Disaponted there's not more on food. Cure my IBS by diet reduced my arthritis also by diet.
Clearly not a complete discussion on vitamin D however I did not get the impression the study included other things like K2 MK7 or magnesium that are needed to get some of the better outcomes. A bit like a study of use of cement for concrete without including proportion of sand or water or aggregate !! I do not think cement by itself is too effective. My own experience of osteoporosis diagnosed in 2009, did not want to take the drugs and focused on alkalizing my diet, Vitamin D of 4000iu, K2 Mk7 and magnesium. In 4 years was back to a normal reading on Dexa scan. Most people get plenty of calcium from diet but need the mechanism to get the calcium into the bones. K2 Mk7 is this carrier and vitamin D is the mechanism to get from tissues. Must have been some studies as my blood test ( the way to really find out your levels ) had a scale on the report. So some one must have created this set of levels for deficient, adequate etc. Sorry not impressed.
Dr John Campbell was in my opinion dismissed on his advice on Vid D + K2. It was disingenuous on the "put down" by ZOE. John was too much a gentleman to argue back. Remember if it was not for John Zoe would not have the profile it currently enjoys... On a parting note ZOE is doing a good job 🕊
I completely agree, while I support what Zoe is doing, Dr Tim Spector seemed to dismiss Dr John Campbell's opinion on vitamin D.
I have VERY high regard for Dr John Campbell. I started taking D3 and K2 when he suggested it and haven’t had a cold since (2 & 1/2 years.). GP says my vit D is on the high side and I’m happy with that 👍
My level is 140 nl / ltr but still had cold last week. Not the panacea but did feel it helped..
Could it possibly be because of the misinformation on COVID that he promulgated? Ivermectin, anyone?
JC was also incredibly pro-vaccine but now is anything but! He's gone full 180 and talks about huge harm from it. I can't trust him. I think once he found how much income KZhead provides people with millions of subscribers he just thought he'd flap about riding the current trend to keep people watching now that the novelty factor of Covid is over.
Need good magnesium and K2 intake and Vit D to reduce fracture risk
D3 plus K2.
I so wanted to learn more about Vitamin D. Disappointed that the conversation was interrupted to talk about Omega 3.
I get tons of sun in the Deep South and my vitamin D level was low and also my son’s.
Even wildlife and animals that live outdoors have low VitD.
Wow I am an older type 1 diabetic and do a lot of exercise suffer from knee pain my trainer after watching your show said to try vitamin D which I started a week ago. It worked for me no more knee pain.
I am a vegetarian in Norway and I take algea based DHA and EPA Omega 3 supplements. I thought this was readily available everywhere. I also get ALA Omega 3 from flaxseed oil and ground flaxseeds that I eat every week. I am surprised that preventing heart disease is the main benifit that has been observed. Considering that heart disease is lower in Vegetarians and almost non existent in Vegans, it would be cool to know if vegetarians are getting the same benifits, or if the main benefit is mostly in fixing the fat ratio for people eating saturated fats ever day
Hi Do you have evidence about the lower heart issues amongst vegetarians? Could this be down to other factors such as people going V for health reasons so maybe they are quitting cigarettes, alcohol, and confectionery too....
@@PatrickHutton The vegetarian adventist Christians are the culture on Earth with the highest number of centenarians, thousands of members, and death recorded back to the year 1900. They have also been extensively studied for this very reason, for about 70 years now with hundreds of papers published. You can hypothesise that their diet plays a minimal effect and other parts of their lifestyle and culture is more important... ...but because no group is 100% the same, there are 10% of adventists that are omnivores, and around 5% that are vegan, and similarly many pescetarians. So through the adventist studies we have been able to research the difference between Adventist vegetarians and omnivores etc. These are all people that live by the same values, but only have differences in diet. In these studies the vegans do best, than the vegetarians, followed by the pescetarians and the omnivores do worst regarding disease and mortality. Studies like these are the best data anyone could ever create
Vitamin D helps with immunity , glad some research is being done. I wonder how big pharma can make money from this?
They can't - there are no patents and it's cheap to make.
Not news, known for freaking decades.
Easily - just jump on the bandwagon. Vitamins are already a multi billion dollar industry.
pharmaceutical companies can instead hinder this, precisely because they have nothing to gain from it. So they are pushing to lower the guard levels to prevent people from protecting themselves, at a low price, from health problems that would see the pharmaceutical companies themselves no longer be able to sell their medicines.
The research has already been done. Our ancestors have proved that sunlight is required to survive. That’s it. Put the sun out and the human race will become extinct.
Hey JoAnn Really Informative video. Btw I was wondering if you need help with edit on your videos and also make highly engaging shorts out of them. Or KZhead management ?
Some of us, such as myself, are very intolerant of both fish oils and fish consumption. I take a high dose of Vitamin D3 once a week instead, which doesn't contain any fish
Yes, I’ve tried lots of supplements but never found one that didn’t cause indigestion etc
What about omega-3? Fish and fish oils are supposedly a much better source for it compared to plant sources.
@aliasgharkhoyee9501 Yes, fish is a better source of omega 3, but if you start vomiting as soon as fish or fish products, including fish oil capsules, are consumed, then it has no benefit at all. I grind a combination of seeds with omega 3 content and sprinkle a tablespoon over whole oat porridge every morning instead, and as said earlier, take a high dose of Vit D3 once a week as well
@RichardLaurence I've found that Vit D3 doesn't cause digestive problems ... get 40,000 iu (1mg Calciferol in 1 capsule) once a week
I have Ankylosing Spondylitis and osteoporosis. I take Vit D with calcium daily, works wonders. Also, algae is plant based, so there will be plant-based alternatives. Nice to see Zoe finally getting on board with Vit D. Thanks
“Plant based” is a red herring and can provide D2, but D2 is a very inefficient way to boost serum levels of D3. The best food source for D3 is wild salmon.
@@inca3370 No, what is K2 and how will it help please?
I agree with the other comment. Add Vitamin K2. It activates multiple important proteins that handle calcium metabolism. Also, since vitamin d improves calcium uptake in food and there is plenty of calcium in food, you would probably do well to skip the calcium supplement. Simple google K2 and bones.
@@peterandrews5956thank you. 🙂
If the person needs omega 3 because they are vegan, then the person in question will not eat fish-based omega 3 no matter how much you nag. And considering that the fish gets its omega 3 from a plant-based diet, it might be better to also offer it to the vegans.
or people could just eat algae oil....
bran oil
@@Starship_X that's what i was trying to say. in the program they say that vegans can get deficient in omega 3 so they should eat fish oil.
This assessment is insanely insufficient since it seems to demand proof of efficacy of Vitamin D. When the first question should be whether vitamin D supplements cause negative health effects. What I have read is that there is little risk for 5000 iu a day. Then as to the efficacy, then there are so many random factors related to sun exposure and diet, how could this fool argue that we need to prove that D is needed for any individual. COVID is not unique and yet she admits the benefit. We give people the shot without determining whether the person has immunity, but that is a different case where too much vaccination can turn off the immune system. No such behavior has ever been shown for D.
i dont think so
"Rheumatard" ha ha
Why wait ??? By the time a study is done, many would have died 😮
Fish based supplements is a big industry and of course they'll be more support for it in terms of money, advertising etc but the fish don't make omega 3 DHA & EPA. It's because fish eat the algae. Therefore algae based supplements is a safe, reliable, contaminate and sustainable way to take omega 3 DHA & EPA.
CORRECTION: EPA and DHA come from marine source, algae. Fish eat the algae to get theirs.
People love wasting money on supplements instead of exercising and eating a good diet.
Maybe that's because there is so much conflicting information given by "experts" on what a good healthy diet is? And not everyone has the mobility to do so called "recommended" exercise
I read that our bodies are evolved to get only 10% of our Vit D needs from food, and 90% from sun exposure on skin. That's why most folk need to supplement as even a good diet does not contain enough.
A few weeks of good meals does not fix a lifetime of a poor diet. A few weeks of higher vitamin d levels will not fix a lifetime of deficiency. It is not that vitamin d fixes the problems it is a long term shortage that causes them.
🤔this lady
It's nice to finally hear someone acknowledge the environmental implications of fish oil supplements. I've always found it a little sad that health conscious people with good diets take these supplements for what is probably minute positive impacts on their health
I ❤ 🐟😋
If you're not eating fish for ethical reasons, then you aren't going to take a fish oil supplement!
It doesn’t need to be fish oil, omega 3 comes from the algae that fish eat, not from the fish, and you can get algae-based omega 3 (that’s how I get mine).
shes not correct
