Could Vitamin D be the Key to Fight off Aging?

 

A recent study published in the American Journal of Clinical nutrition found conclusive evidence that people taking daily vitamin D3 supplements exhibited less telomere shortening than those taking a placebo. 

Telomeres are the end caps on chromosomes that serve as protection. Over time, those end caps shorten due to wear and tear and leave the chromosome more vulnerable to the signs of aging, including diseases linked to aging.

This study showed that such supplements could possibly deter biological aging by a significant amount, especially when taken in conjuction with regular exercise and a healthy diet. 

While reasonable data was collected in support of vitamin D countering biological aging, there is still much more research to be done to further understand how substantial the effects are and how/if the daily recommended guidlines for vitamin D instake should be adjusted.
