Vitamin D levels advised

welcome back it's still wednesday the 17th of november a little more detail on this paper we've been looking at here that's showing that uh higher levels of vitamin d in the blood could be protective against severe illness and death and some pretty convincing data really now before we get down to this one of the headlines on the last video was that these paper authors are saying that we need higher levels of vitamin d when we don't get the sunshine four to ten thousand four thousand to ten thousand international units of vitamin d per day extra if you live in the north of england like me and you're not getting any sun and that should be taken with 200 micrograms of vitamin k2 is what these authors are suggesting now i've just been reading some of your comments on the first part of the video and a lot of people you a lot of people have said well there's no money in vitamin d it's generic you can make you can make it really cheaply it's um it's not a problem um you can't really sell it and make a lot of money on it therefore pharmaceutical companies probably wouldn't be too interested in running expensive trials on it which is probably true but you have so others have said we do need an interventional trial and we do and really the question has to be asked is why have we not had a large-scale interventional trial on something which is potentially so efficacious and so cheap both uh both quite interesting questions to be quite honest so this is the paper we're going to carry on looking at it now and some pretty interesting things about general health here as well as specifically covered now they point out deficiency of vitamin d limits the performance of systems in the body resulting in increased spread of the diseases of civilization now these are diseases like obesity high blood pressure diabetes and again these do seem to be more common in areas where there's low vitamin d certainly vitamin d deficiency can lead to high blood pressure and we know that that is a significant covered risk for example so a lot of diseases of civilization cancer of the colon ischemic heart disease a lot of these do seem to be related to low levels of vitamin d and also reduce protection against infection and these papers that this paper saying reduced effectiveness of the vaccine now i've been asked this an awful lot we know that low levels of vitamin d mean that the immune system doesn't work as well does that mean the vaccine doesn't work as well and that is this is saying yes that if people do have low vet levels of vitamin d and they're vaccinated then the vaccine probably won't work as well they won't generate such a good immune response so another reason another reason to have good levels of vitamin d now covered fatality rates covered fatality rates correlate with the elderly who might live in a facility where they don't get out very much the elderly do tend to stay at home a lot they don't get the sunlight therefore they are lower in vitamin d and we know from large scale epidemiological studies that older people are lowering vitamin d as are people with dark colored skins because the darker the color of the skin the more slowly you will make vitamin d and we know that people with darker colored skins living in a particular latitude in north america or north of england or wherever it is darker coloured skins people do have lower levels of vitamin d um comorbidities well covered fatalities correlate with comorbidities but there again as we've just noticed a lot of comorbidities correlate with low levels of vitamin d so what is the absolute prime cause then of course vitamin d levels go way down in winter when we don't make the sun when someone doesn't make the vitamin d in the skin and um when do we get more colds and influenza and coffee outbreaks it's in it's in it's in wintertime of course so blood levels of 29 grams a mil that's 59 nanomoles a liter it's that's that 20 nano grams of mill is exactly the same as 59 moles a liter sufficient to stop osteomalacia now osteomalacia is the softening of bones now what used to happen particularly in children was the bones were soft and especially the weight-bearing bones they would become bent and they would get bent legs spent long bones bow legged we used to call this and uh that was caused by the um the lack of vitamin d meaning that the bones were um at the bonsai austrian malaysia but you can prevent rickets with just a relatively low level 29 grams per mill is enough to prevent rickets but what we're saying here is that to prevent other things you need much higher levels so ricketts is protected first before we're protected from other things these authors are saying it's preferable to have 40 to 60 nanograms per mil that's 100 to 150 nanomoles per liter and they're also saying that to get those kind of levels you need to be taking six to ten thousand units of vitamin d per day to get up to those kind of levels because we're not making it from the sunshine we're not out in the sunshine all day now there's vitamin d receptors now definitely in bone of course but also in the intestines so we know for example that low levels of vitamin d are correlated with higher levels of colon cancer so these vitamin d receptors are actually all over the body the activated form of vitamin d is a widespread hormone acting on many different parts of the body um vitamin d recep receptors in the pancreas again low levels of vitamin d are associated with prostate cancer and people that had prostate cancer seem to do better if we bunk up their levels of vitamin d such as simple intervention why isn't this being done it's so simple to do and immune system cells all seem to have vitamin d receptors all of them and vitamin d is also a powerful epigenetic regulator now epigenetics is kind of complicated but what epigenetics means is that we're born with a certain set of genes but the way that we live we can't change that set of genes that you're born with that's determined at the moment that the sperm met the egg when you're a zygote at the point of conception that can't be changed from that point on but the the genes which are switched on and off are influenced by the environment in the uterus and the environment after uterus when you're born in other words and these are epigenetic factors so epigenetics is the way genes are kind of turned on and off and vitamin d is important to turn on good genes is what this is saying it's an important epigenetic regulator influencing more than two and a half thousand genes now this is incredible active in any one human being you've probably got about 21 000 active genes it was a very big surprise when we found out there were sophia active genes we had thought there was at least 100 000 active genes in people but with the advert and the human genome project we now know is only about 21 000 genes so we see about 10 or more more than 10 of genes require vitamin d for their normal activation the hormonal form of vitamin d which is derived from the vitamin d from the diet and from the sunlight this is how important this is because of course we are tropical creatures we are evolved designed for the uh to live in the sunshine and evidence of that coming up as well so genetics of course it's mutations that cause cancer so there's increased cancer risk diabetes mellitus especially type 1 the autoimmune diabetes mellitus is associated with low levels of vitamin d but probably diabetes too as well definitely acute respiratory tract infections are more common in low vitamin d and viral lung infections that cause acute respiratory distress syndrome particularly so way beyond way before covered it was known that um people are more likely to develop acute respiratory distress syndrome where the alveoli feather with fluid which is the big problem it covered of course it was known that people with high levels of vitamin d are protected against that regardless of the viral cause of that illness so this this is not particularly new chronic inflammatory diseases like rheumatoid arthritis low vitamin d is a problem autoimmune diseases like thyroid disease diabetes mellitus ulcerative colitis crohn's disease all of these are more of a problem in low levels of vitamin d and multiple sclerosis is a big one now i mean multiple sclerosis we've always known that it's less common near the equator or especially if people were brought up near the equator and now hundreds of people have written to me saying that they are so much better uh their multiple sclerosis is so much better now they're taking comparatively high doses of vitamin d so it obviously would have been better to take it from childhood and probably hopefully prevent the vitamin the the vitamin that the lack of vitamin d deficiency will prevent the multiple sclerosis but that's too late now but if the multiple sclerosis is already there the vitamin d does seem to um help it's an immunomodulatory properties it's an immunomodulator in other words if there's not enough immunity vitamin d will turn immunity up if there's too much immunity causing inflammation vitamin d will turn it down it's like a kind of homeostasis we don't want too much immunity causing inflammation we don't want not enough meaning we get rampant infections and vitamin d just seems to modulate that it almost brings about a homeostasis of the immune response which of course is exactly what we want and it regulates the innate and adaptive immune system so innate immunity acting against a wide variety of organisms adaptive immune system the acquired immune system which results in cellular and humeral immunity as we've looked at before and particularly on that it's now clear that there's vitamin d receptors in all in all of the immune cells it would appear certainly we can say for sure there's vitamin d receptors in the monocytes which migrate into the tissues and become the macrophages absolutely vital immune cell the big eaters and the macrophages also release a full range of cytokines that coordinate the immune response and the inflammatory response and indeed to a large extent the wound healing response as well the t cells the t lymphocytes the b cells the b lymphocytes so the t cytotoxic cells that will destroy virally infected cells the t helper cells which will stimulate the b cells and it's the b cells that produce the antibodies and all these depend on vitamin d activating receptors within the cells otherwise they're not going to work properly the natural killer the nk cells these are the large lymphocytes that will again kill virally infected cells and kill cancer in infected cells and the dendritic cells which actually derive from the monocytes these dendritic cells that they've got dendrites are branches so the kind of branch cells like that in the tissues and what what they are is their antigen presenting cells so if there's a virus or something floating past it's likely to come into contact with a the dendritic armor of these dendritic cells and they will then go to the lymph nodes and stimulate the immune response so that that will be the antigen so these are antigen presenting cells absolutely vital for the immune response and that they need vitamin d to function so moving on to supplements of vitamin d um now without calcium supplementation this is where it gets a bit complicated but we'll go through it is well worth sticking with without calcium supplications without calcium supplementation in other words if you're not giving additional calcium even high vitamin d3 supplement does not cause vascular calcification so we if that's the blood vessel there with its walls we don't want calcium going into the walls of the blood vessel because they would become hard this does happen it's called drain pipe arteries they become hard and inflexible like drain pipes and look like drain pipes on x-rays we don't want that calcification but what this paper is saying is that if we don't give calcium supplements even very high levels of vitamin d does not cause this now it seems that we might have been giving too much calcium for a long period of time so these are my my dad's calcium tablets here there's different brands available i mean they're absolutely huge things i think they contain about a relatively small amount of vitamin d from memory i think it might be um as low as 400 micrograms of vitamin d and they contain about a gram of gram and a half of calcium so all of this is nearly all nearly all calcium they're like huge things i mean look at that i mean you couldn't you couldn't swallow that you just have to suck them that's why the lemon flavored well i wouldn't eat this now just taste the lemon actually but i wouldn't take it anyway because it's just i don't need the calcium have you been giving people far too much calcium but well these tablets are just huge maybe we have because what this is saying is that um we're not going to get this arterial calcification as long as the vitamin d is given without the supplementary calcium so it looks like we might have been giving too much calcium because the body is very calcium thrifty if you've got calcium it won't start passing it out in the urine it's going to conserve calcium and if your calcium levels are at all low or certainly can conserve calcium vitamin d3 supplementation in the range of 4 000 to 10 000 international units now that's the equivalent of 100 to 250 micrograms i needed to generate this optimum level which they're saying is 40 to 60 nanograms of vitamin d in the blood which is 150 nanomoles per liter so basically they're saying you need quite large amounts between 4 000 and 10 000 international units per day to keep your blood levels up at this nice high level that's needed now more more than 20 um nanograms per mil is enough to prevent rickets but it seems that these much and and that's what that's what the advice has been given on enough to prevent rickets but now we know that vitamin d has evolved in so many other things we can now say with some confidence on this paper that this higher range is is necessary and of course in winter we simply won't make it and what this paper is saying is that these higher doses the four to ten thousand units remember we tapped into an email uh last year and anthony fountain said he was taking six thousand units a day and he's a relatively small guy so you know a bigger guy might need ten thousand that is because that is quite quite conceivable um pity it wasn't uh pushed out on the general population as much as we would have liked it to have been but at least he was uh helping his own health by taking six thousand units a day which would be good anyway um the thing that people haven't known about much in the past is the role of vitamin k2 now direct quote from this paper so taking these higher doses four to ten thousand units of vitamin d a day has been shown to be completely safe when combined with approximately 200 micrograms of vitamin k2 is what this paper says direct quote now of course i can't tell you what to take we're discussing this paper for academic reasons but uh that's interesting so myself vitamin k2 of course is uh fat soluble so the fat soluble vitamins are adequ a d e and k now i am not advertising any brands but um this is just a vitamin k2 i got 600 microgram dose um the vitamin k is in available for many other manufacturers i do not get any uh i don't get any uh money from any any pharmaceutical people for advertising their drugs but that's 600 micrograms so i'm taking one of those a week i'm taking an extra 600 micrograms of k2 a week and the idea with that is that the vitamin k2 will take the calcium instead of it high calcium levels going into your blood uh the high calcium levels will go into your bone uh or rather rather they won't go from your blood into your tissues because it's okay so being in the blood but you don't want it to go into the tissues you don't want calcified blood vessels but you do want calcified bones of course otherwise you're going to get soft bones and osteoporosis which is is lack of bone mass which of course is a huge problem so that's what this these uh authors are saying and it really is it is worth taking time to read this paper because it's absolutely excellent it's quite readable um it's not a simple read but it's not the non-scientists can read this and understand it it is um it is a very comprehensible piece of work and in my view a very thorough piece of work which is of course why i brought it to you so the authors of this paper are saying that four to ten thousand units of vitamin d a day in winter that's 125 micrograms 100 micrograms 250 micrograms rather so so like that these again i'm i absolutely promise i'm not making any money advertising these these are just some i've been using myself these are 25 micrograms of vitamin u vitamin d 25 micrograms and 25 micrograms is a thousand international units so so this is saying take four to ten of these uh a day this would be saying according to this so that's that's actually quite a few tablets isn't it that's like uh you know it's like a it's kind of what's that one two three four five six seven so it's easily saying you could take those seven to give you seven thousand uh news a day as i say i i can't describe for you um i'm only telling you what this paper says for for academic interest so um there you go taking it with a vitamin k2 but you see if you take if what's certainly true is if you've got high levels of vitamin d in the blood that's going to increase the amount of calcium that's absorbed from the gastrointestinal tract and if you're eating a bit of cheese and drinking some milk then you'd be getting quite a bit of calcium you know the idea that you need these huge extra ones may turn out to be um not quite what was needed new knowledge will probably demonstrate that in the future and this paper does comment again direct quote so this knowledge about uh about the uh large doses of calcium but you need the vitamin d and the vitamin k2 in preference and you can take the large doses of vitamin d as long as you take a little bit of vitamin k2 it's saying this knowledge is still not widespread in the medical community and obsolete obsolete warnings about the risk of vitamin d3 overdose unfortunately are still commonly circulating even amongst doctors now doctors these days are very uh guideline driven and it can take government guidelines uh an awful long time to um to change i remember we had this when the uh when the um the the helicobacter pylori eradication therapy first came out it took dog tourists ages to start eradicating helicobacter pylori i was aware of it for about 1991 and it wasn't being commonly done really until the late 90s such a pity there's such a delay on these things um now um acute respiratory distress syndrome and cytokine uh cytokine release syndrome cytokine storm so the cytokines are released that causes this massive inflammatory reaction and that causes the acute respiratory distress syndrome and that's what kills people so vitamin d is able to inhibit the underlying metabolic pathways which cause the cytokine storm so again lack of vitamin d could mean more cytokines released and more risk of cytokine storm vitamin d3 is a protective role against acute respiratory distress syndrome particularly caused by sars coronavirus 2 because it does other things to the ace2 receptors and and makes them less likely to cause the the cytokine storm in the lungs a rapidly increasing number of publications are investigating the vitamin d3 status of sarcoidovirus to patients so this is being looked at more as an observational study rather than interventional study unfortunately but these studies have confirmed low vitamin d levels in cases of severe courses of infection so there's no real doubt about this the people that are low in vitamin d have more severe infections i mean there it is that that's the fact as stated by the paper low vitamin d levels in cases of severe causes of infection now of course on this channel we always give evidence and i could give huge amounts of evidence for everything we've said so far but of course that will make it remarkably boring for you but let me just give you an example so here's some of the example here's some of the evidence for this statement here low vitamin d levels in cases of severe courses of covered infection um so there is lower vitamin d levels in people that get more severe illness now here's the references that support that and these are all hyperlinked i can't put them all in in the description because um the only uh youtube only allows you so many words but these are all papers that show that and if you go to the original paper you can you can click on any of these links we're dealing with massive amounts of evidence now a lot of these are relatively low um numbered papers with very relatively low numbers of patients in and that's because a lot of these papers are carried out by the clinicians themselves because drug companies of course have no interest in spending a lot of money on vitamin d research because they can't sell it and get a lot of money back why governments aren't researching this of course is a completely different question government should be researching this and publishing the data and advising the populations accordingly that's a different question positive results from vitamin d treatment earlier the better of course preferably before someone gets sick and again again some references there for that these references are all supporting that contention so i haven't put this all the way through because it would become a remarkably boring talk but it is all it is all there um you know if you want to see it click on the original link and you can click on all these hyperlinks and i haven't clicked on them all myself but but if they are there so conclusions we this is the paper authors recommend raising serum blood levels above nanograms per mil that is a hundred uh 100 to 150 nanomoles per uh liter so they want to raise it to at least 50 nanograms per mil and the reason for that is to prevent or mitigate new outbreaks due to escape mutants or decreased antibody activity now the thing about the vaccines is that vaccines encourage the mu they encourage the survival of mutations which are resistant to the immunological response generated by the vaccine but this doesn't work like that the vitamin d just greatly increases the capabilities of your own immune system so it'll work against anything all variants of course because it just increases your immune system so carrying on with the vaccination we can we could get a vaccine escape mutants which would be uh which wouldn't be good and and so as i said this was done when vaccines weren't available so this is showing good results before vaccines patient with sufficient sufficiently high d3 serum levels preceding the infection were highly unlikely to suffer a fatal outcome there you go patients with sufficiently high serum levels preceding the infection were unlikely to suffer from a fatal outcome so this idea as we said pretty well everyone agrees that people with low vitamin d levels don't do um don't do as well what some people say though is it's the illness which lowers the vitamin d levels this is saying no these people were tested before they became ill and the prediction was still valid and i i'm convinced by that personally this correlation should have been good news when vaccination was not available but instead it was widely ignored now why would governments want to ignore this and instead seemingly spend all their energy promoting vaccination now vaccination is important we're not saying this is not an anti-facts video please don't think that we need vaccination but why would governments apparently ignore the beneficial effect and the the immunity enhancing effect of optimizing people's vitamin d levels thereby optimizing people's vitamin d status therefore making people get less sick i really don't understand why that was widely ignored um i tried uh david davis tried we did a couple interviews with david davis npu who brought this up in parliament several times um but it doesn't alter the fact that it was widely ignored by the chief medical officers in the united states and the united kingdom if you meet them ask them why because i i don't know the low threshold for healthy vitamin d levels should lie at approximately one to five nanomoles or one two five nanomoles per liter or 50 nanograms per mil not the 20 nanograms per mil that is necessary for preventing rickets so these recommendations you could argue i mean we've known that vitamin well people have known that it's even before my time people have known that vitamin d prevents rickets since well victorian time so you know this is 120 years ago and and yet when these levels the the levels that were required to prevent rickets were worked out literally 100 years ago it isn't more than 100 years ago now um they don't seem to have been updated what is what was going on what you know why don't the medical authorities update this information and this paper is saying which would if if this was done if everyone was put up to a 50 90 grams per mill this would save most lives reducing the impact even for patients with various comorbidities so this is going to protect everyone including those with comorbidities to some extent or to a large extent this uh to our knowledge is the first study that aimed to determine and optimum levels of d3 to minimize covered 19 mortality so there you go that's the first time that this has appeared in the literature and the answer is we need to get our vitamin d levels up to 50 nanograms per mill according to this paper which is 125 nanomoles per liter therefore everyone should get their vitamin d levels measured and doctors should titrate the vitamin d levels up to these optimum levels according to the authors of this paper of course most doctors won't test for your vitamin d levels because it's quite expensive but that's surely this would be a cost effective very cost effective strategy you would have thought implications for herd immunity paper said it seems clear that a good immune defense does not uh provide protection against physical infection in other words you'll still be exposed to the organisms and if you're exposed to the organisms you'll generate specific active acquired immunity so the vitamin d levels aren't stopping you being exposed to the organism they're not stopping you generating immunity to the organism but they are stopping you getting sick and dying when you are exposed to the organism so that's a win-win situation we still get herd immunity but no one dies well very few people die that is just brilliant that's that's what we want uh this protection was most effective at about 55 around about 55 nanograms per mill the way if you watch the previous video we actually looked at this on on the graphic here and this is the graphic for the um the negative inverse correlation and we found out that when we got to this level here of about vitamin d levels of about 50 nanograms per mil theoretically this green combined late dated line went down to a death rate of zero whereas for people with the uh lower levels of vitamin d here we see that the the mortality was much higher they were much more likely to die i mean it's just absolutely like those lines are clear people with high levels of vitamin d are getting lower levels of death it's a it's a clear inverse correlation and this paper is given the evidence to argue that it's not a cause of the illness but the illness is a cause of the lack of vitamin d now another reason i'm convinced by this it's kind of a bit more philosophical really um and and it's this um you know i've probably got some of these uh we've got that one up there yeah i've got that paper there look um traditional living populations in east africa have a mean serum 25 hydroxy vitamin uh concentration of 115 millimeter or higher now of course you and i uh deny it as we might try to uh we are hunter-gatherers that's what we are we are designed evolved to survive by gathering and foraging for roots and vegetables then once a week once a month the young men in the tribe might make a kill and we'll eat meat we are hunter gatherers you know we're fishers we're foragers for limpets on the seashore that's what we are and of course all those things are outdoors so this is uh traditional living populations in east africa people who live in a traditional hunter-gatherer way natural vitamin d levels seen amongst traditional hunter-gatherer lifestyles even even when there's lots of infectious diseases around in a natural environment the vitamin d levels go up to 45 to 50 nanograms per mill so these people add way higher that's 110 to 125 nanomoles per liter these people living a natural lifestyle had way way higher levels of vitamin d than we do in our natural circumstance here where the government just wants us to get it above 20 or even up to 30 according to the world health organization according to the world health organization if you've got 30 uh nanograms per mill you're not deficient that they count that as sufficiency but that's not good enough for the hunter gatherers they are 45 to 50 because they're living outdoors all the time a traditional lifestyle which we are supposed to live that our physiology your physiology your anatomy is that of a hunter-gatherer and if you want to try and change that by eating cream cakes and uh not exercising not working and doing things that are inconsistent with hunter-gatherer lifestyle we'll get these so-called diseases of civilization that we talked about the obesity of the heart disease cerebral vascular accidents the hypertension all of all of these diseases associated with uh what we're calling for want of a better term civilization um who advice may not be correct therefore so 39 grams per meal is considered by the who to be the threshold of sufficiency so they're saying you've got sufficient vitamin d if they're above if it's about 39 grams per mil whereas people with traditional lifestyles have 40 to 50 nanograms per mil now if these people with traditional lifestyles are exposed to even greater amounts of sunshine the vitamin d levels still don't go higher so it looks like human physiology is kind of optimized this is the optimum round about 50 as the optimum vitamin d level but most of us are way below that way below that future meditations of the sas coronavirus 2 uh vaccine escape immune so as we've said vaccines could cause immune escape resulting in organisms or types of viruses that are not where the vaccines no longer protect us but for the vitamin d that will still work it will still work and they say the entire population should raise their serum vitamin d levels to be at safe levels as soon as possible direct quote from the from the paper as long as enough vitamin k2 is provided the suggested d3 levels are entirely safe to achieve by supplementation according to the authors of this paper now of course this is for academic interest only uh i'm not advising you what to do the authors of this paper not advising you what to do but that's what they say that's a direct quote as long as enough vitamin k2 was taken and that's probably about 200 micrograms per day no no we'll look at the vitamin k2 in a minute actually i think the recommendations are a microgram per kilogram per day but this is saying if you take a lot of vitamin d which we need to take because we don't get it from the sun then you probably need to increase that a bit and the paper also mentions the importance of selenium magnesium zinc vitamins a and e you're very unlikely to be short of vitamins a and e i would have thought but um selenium magnesium and zinc people can be short of and all the all of these things are important it should also be controlled for and supplemented where necessary to optimize the conditioning of a well-functioning immune system so we need to optimize our immune system now i am going to tell you how we can in fact i think i'll do that next this can be proved or disproved quite easily um all we need to do is uh test positive pcr contacts an effective person for d3 levels immediately in other words people that are likely to have been infected just get a few thousand of them so as soon as someone tests positive round up all the other members of their household test the other members of the household for vitamin d levels and then you'd know what they are obviously their vitamin d levels would not have been decreased by illness because they've just been exposed to the virus a few hours ago because a member of their household has just tested positive so before any onset of any symptoms so as soon as they become infected even before the start of the incubation period test the vitamin d levels and then follow them for three weeks relate the course of their symptomatology to d3 levels it's that simple the same results are shown above must be obtained if the hypothesis is correct now why the heck are governments not doing this it is so it's not even an interventional study you don't even have to organize a clinical trial all you have to do is take people just 10 20 000 of them it would be so easy to do that have been exposed to the virus by a household contact who've just tested positive test all those contacts uh vitamin d levels because we know they're they're at increased risk of infection from the same household follow their course of illness and you'll find according to this paper that those with higher vitamin d levels do better those with lower vitamin d levels are more likely to get very sick more likely to be hospitalized more likely to be ventilated more likely to die why on earth don't we do that you know the fact that medical authorities are not doing this because it's such a simple observational study really is getting into the bounds of negligence as far as i can see unless there's some other reason that they haven't sought fit to to share with the hoi paloy like you and me um there's some reason they haven't told us or they're negligent i really don't see an alternative now just before we finish i'm just going to look at vitamin k2 briefly here now this is directly from the british government site so this is live so we can take this as definitive information really this one's on vitamin k good sources of vitamin k green leafy vegetables such as broccoli and spinach so eat plenty of broccoli and spinach vegetable oils don't want to eat too many of those but cereal grains so um green leafy vegetables and uh cereal grains would be good small amounts of vitamin k can be found in meat and dairy foods but the main things there that are good to eat green leafy vegetables and uh vegetable oil as i say we don't want too much vegetable oil because it's often not the right kind of fat but certainly cereal grains we want so you can get vitamin k uh get get the vitamin k that we need easily from those um from those healthy sources how much vitamin k do i need adults need approximately one microgram of vitamin u one microgram a day of vitamin k for each kilogram of body weight so in other words 65 kilogram person will need 65 micrograms but this is saying this paper saying take 200 micrograms extra if you're taking these higher six seven eight nine ten thousand international units of vitamin d a day so microgram as we know is a thousand times smaller than a milligram you should be able to get uh the vitamin k that you need from eating a varied and balanced diet so that that's true but it but this paper is saying just to make it completely safe if you're taking high doses of vitamin d as a tablet uh do um take some k2 as well according to this paper any vitamin k your body does not need is stored because it's a fat soluble vitamin of course what happens if i take too much vitamin k there's not enough evidence to show what the effects might be of taking high doses of vitamin k supplements each day what does the department of health and social care advise you should be able to get all the vitamin k you need by eating a varied and balanced diet if you take vitamin k supplements do not take too much as this might be harmful and they're saying taking one milligram or less of vitamin k supplements daily is unlikely to cause any harm and i'm taking 600 micrograms a week which is uh 0.6 of a milligram so that's way under what they considered to be uh to be harmful so from that it looks like it's uh it's pretty safe to take at the levels suggested by the paper um but of course you'll have to decide that for yourself this is just for academic interest so there you go uh those those british governments simple guidelines are really uh very helpful so some interesting questions for the chief medical officers next time you meet them why on earth aren't they doing this simple observational study uh do that on 10 20 000 people the data would be definitive we are predicting here that it will show that people with low levels of vitamin d don't do as well and that by bunking it up we could massively improve the health of the population for essentially no cost and yet it is not being done strange but true thank you for watching
