It's only a month into 2014 and already there have been nearly 70 new studies on vitamin D. Vitamin D supplementation is certainly a hot topic.
Ad nauseam, we are bombarded with messages about taking vitamin D supplements. The recommendations have been so effective that now almost 50% of Americans take vitamin D supplements.
But, do they really prevent disease?
According to the prestigious medical journal, The Lancet, "The weight of the evidence in terms of randomized controlled trials suggests that vitamin D doesn't offer protection against fracture, MI [heart attack], ischemic heart disease, stroke, or cancer," the most common causes of death in the U.S.
The study's authors agree: Let's "put more emphasis on the development of evidence-based cutoff points for vitamin D inadequacy" rather than wasting more time and money trying to disprove the obvious.
Vitamin D is not a vitamin. It is a hormone. Our body makes it when our skin is exposed to the sun. If your vitamin D level is low, go outside.
