Oral Nicotinamide / Skin Cancer Prevention Dose
At 500mg twice daily orally, niacinamide has a landmark clinical application beyond cosmetic use. A 2015 NEJM study showed it reduced new actinic keratoses by 11% and non-melanoma skin cancers by 23% in high-risk patients — one of the most compelling longevity-related dermatology interventions. This is distinct from its topical cosmetic use.
Oral 500mg nicotinamide twice daily for skin cancer risk reduction in high-risk individuals — discuss with your dermatologist first.
