It seems there is nothing the sunshine vitamin can’t do.
Vitamin D, which you can generate from sunlight exposure, or get through certain foods like salmon or fortified milk, helps keep the body’s immune system, bones, muscles, and heart healthy.
A new long-term study published Wednesday finds that vitamin D supplementation may also play a significant role in aging.
The study, which appears in The American Journal of Clinical Nutrition, found that those who took vitamin D supplements over four years slowed the shortening of their telomeres. Telomeres are the protective ends of chromosomes that shrink with age. “The finding that these telomeres seem to be protected against shortening, and that their length was being preserved by vitamin D supplementation, suggested that vitamin D may have a role in slowing biological aging,” says Dr. JoAnn Manson, coauthor of the study and chief of the Division of Preventive Medicine at Brigham and Women’s Hospital.
