It has become abundantly clear that vitamin D deficiency is a growing epidemic across the world and could be contributing to hundreds of common health problems. In fact, correcting your vitamin D deficiency may cut your risk of dying from any cause by 50 percent, according to one analysis.
If this sounds too incredible to be true, consider that vitamin D influences nearly 3,000 of your 24,000 genes. This occurs via vitamin D receptors, which can be found throughout your body, and should come as no great surprise given that humans evolved in the sun.
Vitamin D Beneficially Affects Gene Activity
Just one example of an important gene that vitamin D up-regulates is your ability to fight infections and chronic inflammation. It also produces over 200 anti-microbial peptides, the most important of which is cathelicidin, a naturally-occurring broad-spectrum antibiotic.
This is one of the explanations for why vitamin D is so effective against colds and influenza.
According to a January 2013 press release by Orthomolecular Medicine,1 there are now 33,800 medical papers with vitamin D in the title or abstract, and this veritable mountain of research shows that vitamin D has far-reaching benefits to your physical and mental health. Such research has shown that vitamin D can improve:
Pregnancy outcomes (reduced risk of Cesarean section and pre-eclampsia)
Type 1 and 2 diabetes
Heart disease and stroke
Autism, Alzheimer’s, and other brain dysfunction
Bacterial and viral infections
