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.
