Nicotinomide is the amide form of Vitamin B3 and the precursor of nicotinomide adenine dinucleotide (NAD), which functions as an essential cofactor for multiple cellular processes. Nicotinamide taken orally at a dose of 500mg twice a day helps repair DNA damage and thus can significantly reduce the chances of developing actinic keratosis (pre-cancerous lesions) and non-melanoma skin cancers (NMSC).
