Two flawed studies, a rehashed review, and an editorial published in the December 17th issue of the Annals of Internal Medicine have attempted to discredit the value of multivitamin supplements. Both of the studies were plagued by grievous methodological flaws. In one of the studies, subjects were given low-quality, low-potency multivitamin supplements. Treatment adherence rates and drop-out rates were horrendous in the studies. Nevertheless, mainstream sources are using these reprehensible studies to undermine dietary supplements. The first study examined the cognitive effects of low-potency multivitamin supplementation in aging male participants.  Not surprisingly, the conclusions in the present analysis question the value of multivitamin benefits for cognition. In the other study, […]

The holidays aren’t always a happy time for everyone. People often remember loved ones who’ve passed away or left their lives, which can trigger feelings of sadness, nostalgia, and even emptiness.

A report published on December 9, 2013 in the Proceedings of the National Academy of Sciences explains how vitamin D, long suspected to play a role in the prevention of multiple sclerosis (MS), works to protect against the disease. Acting on the finding of previous research of a preventive benefit for vitamin D in a mouse model of MS, Anne R. Gocke, PhD, and her associates at Johns Hopkins University tested the effects of the bioactive form of vitamin D known as 1,25-dihyroxyvitamin D3 [1,25(OH)2D3] and found that administration of the vitamin prevented the animals from showing symptoms. They observed that immune system cells […]
