Large-scale Vitamin D study on Telomeres, an important Marker of Aging

Vitamin D might do more than support bones and immunity - a new study (VITamin D and OmegA-3 TriaL (VITAL) randomized controlled trial) was recently published by the The American Journal of Clinical Nutrition and it involves 1000 participants, an important hallmark of aging, Telomeres and a very famous vitamin, meaning Vitamin D.

In this video, I break down what telomeres are, what the scientists measured, and what daily consumption of vitamin D3 did over four years. We’ll also talk about practical dosage, who this may apply to, and why checking your vitamin D levels matters.
