Study Finds Vitamin D Slows Human Aging by Protecting Telomeres

Vitamin D is increasingly recognized for its critical role in promoting health among various populations, notably women over 50 and individuals with type 2 diabetes. For menopausal women, adequate vitamin D levels support calcium absorption, thereby reducing risks of osteoporosis and fractures, while also aiding immune function and mood regulation. Beyond bone health, vitamin D’s influence extends to metabolic processes, with recent research highlighting its potential to improve insulin sensitivity in type 2 diabetes patients. Additionally, vitamin D supplementation has been shown to slow telomere shortening, suggesting a protective effect against biological aging. Experts also emphasize that while sunlight exposure remains a primary source of vitamin D, supplementation can be beneficial, especially for individuals with absorption issues or limited sun exposure. Advances in vitamin D analog research further point to potential therapeutic applications, including anticancer effects, by enhancing metabolic stability and reducing side effects.
