Vitamin B3 Supplement Shows Promise in Skin Cancer Prevention
A new study suggests that over-the-counter nicotinamide, a form of vitamin B3, can reduce the risk of certain skin cancers, especially in individuals with a history of the disease, potentially leading to earlier preventive use. The research analyzed data from nearly 34,000 US veterans, finding a 14% overall risk reduction, with greater benefits for those previously affected by skin cancer, though less clear benefits were observed for immunocompromised patients. The findings could influence future guidelines for skin cancer prevention.
