could vitamin b3 prevent certain kinds of skin cancers?

Australian researches released a study that tends to show that taking 500mg of Nicotinamide (a form of Vitamin B3) twice a day can reduce the occurrence of non-melanoma skin cancers by as much as 23%. This study was done with 386 people averaging age 66 with half of the group being given Nicotinamide twice a day and the other half being given a placebo. Those taking the Nicotinamide twice a day were shown to have cut their chances of developing new skin cancers by as much as 23%. Nicotinamide is an over the counter supplement.

Skin Cancer Foundation Senior Vice President Deborah S. Sarnoff, MD stated “The results of this study are certainly promising, but we believe that more research is needed to determine whether or not to recommend vitamin B3 therapy for skin cancer prevention.” Dr. Sarnoff added, “What we know for sure is that everyone should adopt a complete sun protection regimen that includes seeking shade and covering up with clothing, including a wide-brimmed hat and UV-blocking sunglasses, in addition to daily sunscreen use.”
