7 Skin Cancer Prevention Strategies in India That Work

2. Consider nicotinamide (vitamin B3) for high-risk individuals

Nicotinamide, a form of vitamin B3, has emerged as a helpful preventive option for people at higher risk of skin cancer. Large clinical studies show that taking 500 mg twice daily lowered the overall rate of new skin cancers in people with prior skin cancers. One trial reported about a 14% reduction overall, and an even larger 54% reduction when started soon after a first diagnosis. That evidence comes from controlled research and offers an additional layer of defense beyond sunscreen and screening. Nicotinamide appears safe for many adults, but you should talk with a dermatologist or physician before starting any supplement. It is not a substitute for sun protection. In India, access to dermatology varies, so discuss the supplement during routine clinic visits or at health camps. For people with many precancerous spots or a prior skin cancer, nicotinamide could be an option to explore together with a clinician.
