Medicine Changes It’s Mind Every 10 Years, Case in Point, Vitamin D Supplements No Longer Advised

Having been in practice 13 years now, I’ll let you in on a secret: fifty percent of everything you learn or read about in the news regarding health and medicine will be obsolete or wrong, sometimes even harmful, within 10 years or so. Does that mean I should ask for 50% of my money back from my medical school, hmmmm?
Case in point: In the 2000s, a lot of interest in Vitamin D testing and supplementation ensued with the consensus being, take Vitamin D if you don’t get enough sun, have low levels (my lab says low levels are less than about 30 ng per ml), are elderly and at fall risk, have mood disorder such as depression, are at risk for heart attack…the list went on.
Less than a decade later, recommendations have shifted 180 degrees, that is, studies in recent years show no benefit to taking Vitamin D for all the disorder above unless your levels are below 12-20 ng per ml making you Vitamin D deficient. If you are deficient in Vitamin D or your diet lacks the needed 600-800 IUs recommended daily, take Vitamin D (FYI most multivitamins have about 200-400 IUs of Vitamin D).
I’ve stopped supplementing with Vitamin D and plan on checking my levels in a month or two.
If you have been prescribed Vitamin D but are not in fact deficient and have questions or comments, speak to your doctor or contact me on Twitter. Facebook, Instagram, etc.
