The American Journal of Clinical Nutrition is based on data from a VITAL sub-study co-led by researchers at Mass General Brigham and the Medical College of Georgia and supports a promising role in slowing a pathway for biological agin
"VITAL is the first large-scale and long-term randomized trial to show that vitamin D supplements protect telomeres and preserve telomere length," said co-author JoAnn Manson, MD, principal investigator of VITAL and chief of the Division of Preventive Medicine at Brigham and Women's Hospital, a founding member of the Mass General Brigham healthcare system.
Telomeres are made of repeating sequences of DNA, or base pairs, that prevent chromosome ends from degrading or fusing with other chromosomes. Telomere shortening is a natural part of aging and is associated with an increased risk of various age-related diseases.
"This is of particular interest because VITAL had also shown benefits of vitamin D in reducing inflammation and lowering risks of selected chronic diseases of aging, such as advanced cancer and autoimmune disease."
