mikeccolella Posted March 17, 2018 Report Share Posted March 17, 2018 So woman who were deficient in vitamin D and then given 2000 iu daily showed sleep quality declines if there levels rose above 32 ng/ml. There is also evidence that vitamin D in high doses causes disruption of melatonin production see 2nd reference. Michel Rae recently reviewed his intake of vitamin D on longecity and I wondered why he was sticking to just enough to get him at 30 ng/ml and I assumed he was being cautious and for good reason as these studies indicate that even 2000 i.u. May be too much for some of us. I am currently taking about 1000 iu in the 6 months with low sunlight and none in the 6 months with adequate sun. My test in February was 29 and in September it was 30 ng/ml Mason C, De Dieu Tapsoba J, Duggan C, et al.

TomBAvoider Posted March 17, 2018 Report Share Posted March 17, 2018 I'll chime in, even though my post may disappear, as so often happens these days. I am not sure how supplementation impacts vit. D blood serum status - I say this because I've had my status measured once yearly for 16 years now, and I've kept a supplement diary for almost as long. Honestly, my vit. D status seems almost completely disconnected from supplementation. I've supplemented anwhere from 0 to 400IU to 1000IU and my status is all over the place with no seeming connection. This year, it's 26 compared to last year of 31 - and I've supplemented with the same 1000IU from TJ's vit. D3 sold there - and I can't say that I've changed my diet much insofar as sources of vit. D (small amounts of salmon and sardines, mushrooms), or my sun exposure. Also I wonder what the relation of serum vit. D status is to tissue saturation - various tissues accumulate or use vit. D in differing amounts, what's circulating in your blood after a 12 hour fast may have weak relationship to tissue amounts. Link to comment Share on other sites More sharing options...

Matt Posted March 25, 2018 Report Share Posted March 25, 2018 Tom, maybe you should just try a different vitamin D supplement? After using vitamin D (5000 IU +), my levels went up to 304 nmol/L (121 ng/dl).I've never noticed issues with sleep either... I only take between 1000-2000 now.

Guest rudolph marcus Posted April 2, 2018 Report Share Posted April 2, 2018 Just saw a video from Mercola, where he stated that it takes 48 hour for making vitamin d out of your cholesterol and sunshine (UVB) , but, and here is the novice, if you shower with hot water and/or use shampoo/shower gel within 48 hour after your sunbath you wash away the vitamine D out of your skin. I didnot check it further but found it worth mentioning :-) Link to comment Share on other sites More sharing options...
