Could a daily dose of sunshine help us age more gracefully? A new long-term randomized controlled trial suggests it might — at least when it comes to vitamin D.
We spoke with Shanthi Appelö, health and wellness spokesperson for Blue Cross Blue Shield of Michigan, about the study’s findings and what they could mean for everyday health.
The research, conducted by Harvard-affiliated scientists, found that consistent vitamin D supplementation may slow biological aging by helping to maintain the length of telomeres — the protective caps at the ends of chromosomes that naturally shorten over time.
“Telomeres are a bit like the plastic tips at the ends of shoelaces,” Appelö said. “They keep our DNA stable. When they fray or shorten too much, it’s linked to a number of age-related diseases. Vitamin D appears to play a protective role here.”
Before starting any supplement regimen, Appelö emphasized the importance of knowing your levels and consulting a physician.
“Vitamin D is crucial, but more isn’t always better,” she said. “It’s essential to talk to your doctor about whether supplementation is right for you.”
For those looking to boost their levels naturally, Appelö recommends a combination of diet and sun exposure.
This research underscores vitamin D’s growing reputation as a key player in aging and overall wellness. But like many aspects of health, the best approach is a personalized one — guided by science and grounded in conversations with your health care provider.
