Vitamin D, government inaction

well a warm welcome to today's talk it's wednesday the 17th of november and as you'll see it's a fairly gray day outside here in the north of england and i'm going to be giving evidence from a paper today and the authors of this paper are suggesting that to get the optimum amount of vitamin d in the blood to get the best amount of vitamin d in the blood at this time of year adults need to be taking 4 to 10 000 units of vitamin d extra per day that's 100 to 250 micrograms extra vitamin d per day and they're also suggesting that with this we take 200 micrograms of vitamin k 2 to make sure that the calcium that's released by the vitamin d goes into the bones and not into the tissues so i'm going to do this video in two parts because it's quite involved so i'm just going to give a short video now where we get the main points of this across if you've only got five or ten minutes so covered 19 mortality which correlates inversely with vitamin d3 status is what this paper is about in other words you're more likely to die if your vitamin d is low and they're saying that death rate could theoretically be brought down to close to zero now of course they're not saying that death rate ever would be zero because there's always other factors involved but this is a theoretical consideration but it shows the power potentially the beneficial power of increasing our levels of vitamin d in the blood and it's a systematic review and meta-analysis now this is the paper here and of course i always put the links to it uh heidelberg and tubagen in germany um it's a very impressive paper actually you can get the download the pdf you can get the thing this is the full text version i'm on here so yeah it's all there and and this paper actually is is very very well um written it's properly translated and it's quite intelligible if you read this you will you will understand it it's not it's not in scientific gobbledygook at all let's get straight down to it blood calcified dial that's the active form of vitamin d in the blood correlates strongly with the stars coronavirus to infection severity and in death so no one really disagrees with this the question is that some people are saying well it's actually the fact that you get sick that lowers your vitamin d levels well i think it's people with low vitamin d levels that are likely to get sick in the first place and that's what this paper is about and that's what this paper argues for strongly and in my view convincingly and the fact that authorities haven't taken this on by now really is well it's just inexplicable why they haven't taken it on by not by now this really needs to get its way into public health government ordained advice and it's simply not getting there so is it cause or effect so we believe it's cause and that's what this paper is arguing for now the strength of our immune system more or less neglected by the responsible authorities and i think you have to say this is right you know the authorities are focused on social restrictions lockdown measures vaccination measures some might say expensive pharmaceuticals whereas we're not saying that those things are wrong but we're saying we need to get the immune system optimized first and it just doesn't seem to have been a dress fame which was a bit surprising so nutrition physical fitness recreation sleep all of these things very important vitamin d deficiency is widespread in europe and the united states of canada we know that and the interesting thing of the data for this study was collected in march 2021 and it was collected on people that were unvaccinated so this is not data which has been uh affected by uh vaccination is showing an independent a beneficial effect from optimizing vitamin d levels in the blood so it's a systematic literature review retrospective cohort study there was one good european wide study on that so there was one of those and there were seven clinical studies and they came to pretty well the same conclusion now this is good because one is a population study on basically healthy people who became ill and the other the other is clinical studies on people who were ill so two different ways of collecting data but came to essentially the same conclusions and we'll see that they are very very closely related another reason i think these results are correct reported vitamin d levels pre-infection or on the day of hospital admission so the big thing about this was they knew they took people into the study who they knew what the vitamin d levels were before or they took it on the first day of hospitalization and the key thing here is this is before the illness would have had chance to lower their vitamin d levels so it's not after the illness has lowered their vitamin d levels it's what their vitamin d levels were to begin with and of course people with lower vitamin d levels did worse people with higher vitamin d levels did better of course they corrected the results for mortality rates for um for aids sex um diabetes all the things you would expect it was well as a well control study now the results the the what they found was a negative person correlation between uh d3 levels of mortality risk now this pearson correlation is just um a statistical tool and and it's a it's a it's a negative correlation in other words as vitamin d levels go up illness goes down or as vitamin d levels go down illness goes up so just just to just clarify that because i know that can be a bit confusing so if we look at smoking and lung cancer we could look at towns or countries where there's so people that smoke more get more lung cancer so we kind of get an upward trend like that that would be a positive correlation like that more smoking uh causes more lung cancer well there's correlation that's how the cause of lung cancer was first identified but we can also have negative correlations as well so negative correlation like if you look at the amount of exercise and the amount of obesity that would go the other way around it would be the line would be in in that direction it would be the opposite effect so um whereas that one's a positive effect this one will be an inverse or a negative a negative effect between exercise and and obesity for example so so that's what these things are that they are these these are correlations and uh these two two different ways of collecting the data as we said what one was negative zero point four and one one was negative zero point four and a bit so um both negative now if if the correlation is uh negative one that's a perfect negative correlation if it's zero there's no correlation at all if it's plus one that's a perfect positive correlation so we can see it's quite a convincing correlation here and i'm going to show you the lines in a minute now the combined data set uh they found that the the median levels of vitamin d were 23.2 nanograms per meal but as we'll look at they want it to be higher than that so anyway when they looked at the combined data now the more astute of you will have realized that the studies on their own that p-value there is not actually significant and that p-value is not actually significant we need 0.05 or less so really that's non-significant data but when they combined the data sets they did get very significant data which is good so here we have that here the overall negative correlation was 3.9 and that does give a very very significant result uh the regression suggested a theoretical point of zero mortality at 50 nanograms per ml of vitamin d now they're not saying this would happen of course not they're not stupid but it's a theoretical pointer and here are the negative correlations here so they are pretty uh pretty convincing now the green one is the combined data the red one is the population study and the black one is the hospital data but we can see for this put this way of measuring death here so that's increasing deaths up there so as the vitamin d levels increased to increasing levels 10 20 30 so that's increasing vitamin d levels up there we see that the death rate went down and the green line we said there is the combined data and the green line crosses the bottom line there at zero deaths at about just over 50 as we've said so it's a theoretical consideration but that's that would be 50 nanograms per mil of vitamin d but there's very very clear trends there that the the higher the levels of vitamin d the lower the levels of death it's very very clear from that higher levels of vitamin d lower levels of death and we believe that as we've said we believe that this is not an effect we believe it's in a cause because the vitamin d levels were known before the people were ill so it's pretty convincing now a lot more scientific data on the second video but let's just give some brief conclusions now from this the authors say direct quote the data set provides strong evidence that lobe d3 is a predictor rather than just a side effect of a severe infection despite ongoing vaccinations we recommend raising serum 25 vitamin d levels to above 50 nanograms per mil so that is what they recommend and to do that they have found that to do that consistently you need these kind of levels um four thousand to ten thousand international units of vitamin d per day that's 100 micrograms to 250 micrograms per day for adults when the weather's cold like this as an overcast and they also recommend as we'll see later taking 200 micrograms of vitamin k2 with it the fact that governments are not acting on this now that there's so much evidence and i'll be giving stacks of evidence in the next video it really is it's it's hard to understand why governments are not taking action on this now so keep that short and sweet at the moment and we'll look at more data in the next video thanks for watching this short one
