Vitamin D supplements help slow telomere shortening linked to biological aging.
This is remarkable. Vitamin D has long been a polarizing topic in nutrition science, so I wouldn’t treat this as conclusive. “Compared with taking placebo, taking vitamin D3 supplements significantly reduced telomere shortening over four years, preventing the equivalent of nearly three years of aging compared with placebo. Omega-3 fatty acid supplementation had no significant effect on telomere length throughout follow-up.” ~ learn more
