D3 and Mg Supplements not mandatory w/ sun + balanced diet If you subscribed to the @SuppVersity Facebook Page, you will have read the news, already: "Magnesium status and supplementation influence vitamin D status and metabolism" ( Dai 2018 ) - that is both the title and the main results of a recent study from the Vanderbilt University  that is important enough to make it from the short format on Facebook  to a detailed SuppVersity article of its own - the article at hand ;-) The 25OHD-balancing effects Dai et al. observed in their 180 participants (aged 40–85 y) could after all do much more than point towards a reason why everyone and his mama seems to be D-ficient - it could force us to redefine what "optimal" 25OHD levels are - significantly below those many Internet "health experts" recommend.

Your BMI or rather the associated level of inflammation and bodyfatness determines your D3 requirements. I know that I have previously written about estimated vitamin D requirements, but in contrast to previous articles that were based only on 1-3 studies, today's article about the purported vitamin D requirements of the average Westerner, however, is based on the same previous 108 published estimates and new calculations based on the vitamin D status of 13,987 individuals in various studies Veugelers, Pham and Ekwaru used as the observational database for what is a of now probably the most tangible vitamin D recommendation in their recently published study in Nutrients  (Veugelers. 2015).

Old or young, who is going to benefit and who is going to benefit most from vitamin D supplementation during a 12-week resistance training regimen. Unfortunately, we don't have an unambiguous answer - yet!? Ok, I have to admit, I could have kept up the suspense by not giving away the main result of Jakob Agergaard's and colleagues' latest study in the headline, already. On the other hand, by giving away the most relevant information in the headline, I can make sure that future google searchers will immediately refute the claim that "vitamin D is a powerful muscle builder" - it is not. What it may very well be, is a vitamin that is necessary for your long-term success. This is still much different from what you may conclude solely based on the associations that exist between low vitamin D and all sorts of ailments, though. Evidence that vitamin D(3) supplements are able to reduce the risk of bone fractures, diabetes, cardiovascular diseases, cancer, depressio...

If you could simulate a workout at the beach in the petri dish, its beneficial health effect would be all the rage ;-) I am pretty sure all of you still remember the recent post about the literal muscle building effect of vitamin D, right (see " Vitamin D Builds Muscle ")? Me too, and so I was almost tricked to believe I was looking at the Girgis study, when I scanned the contents of the latest issue of Molecular Nutrition & Food Research , in which you'll with the telling title: "1,25(OH)2-vitamin D3 enhances the stimulating effect of leucine and insulin on protein synthesis rate through Akt/PKB and mTOR mediated pathways in murine C2C12 skeletal myotubes". Ah, ok, I see that's not exactly easy to understand. Well, in plain English this means as much as...

If rely on the results of the most recent study from Australia, the answer to the above question probably reads "Yes, to a certain degree it does". It has been a while that a vitamin D study has made it into the SuppVersity news (see previous articles ). The reason for that is simple. I am not interested in study no. 9235235 that discusses random associations of low vitamin D with whatever ailment is plaguing us or review no. 89359252 that presents a selection of papers and concludes: "Man, there are vitamin D receptors everywhere, so it must be the f*** most important vitamin in your body!" The upcoming publication of a paper in the scientific journal Endocrinology did yet appear to be a good reason to stop the vitamin D radio silence. It's an in vitro study, I know, but it could answer a question many of will be interested in. Does vitamin D build muscle? I guess all of you will tell me that, in view of the results of pertinent studies (cf. Girgis. 2...
