A brand new study from researchers at Harvard-affiliated Mass General Brigham and the Medical College of Georgia says that vitamin D dietary supplements may actually slow down organic aging. Yes, you learn that proper.The study, printed in The American Journal of Clinical Nutrition, centered on telomeres—tiny protecting caps on the ends of your chromosomes. As we age, the following pointers put on down, which is linked to age-related illnesses like coronary heart issues, sure cancers, and extra. The shorter the telomeres, the extra worn out your cells are.Now, right here’s the place it will get cool: Researchers checked out information from the well-known VITAL study—a long-term medical trial the place members have been randomly given both vitamin D3 (2,000 IU/day), omega-3 fatty acids (1 g/day), or a placebo. The telomere sub-study adopted over 1,000 folks (ladies 55+ and males 50+) for as much as 4 years.The outcomes?
