Good News for Sun Worshipers: B3 Supplements Can Help Prevent Sunburn

  • Janice O’Leary

Sun worshippers have a reason to rejoice over a new means of protection from the sun’s damaging rays. A recent study confirms the benefits of ingesting vitamin B3 to protect against ultraviolet radiation. The phase 3 study, published in the New England Journal of Medicine, examined participants in a double-blind, randomized, controlled trial who had at least two nonmelanoma skin cancers, such as basal-cell carcinoma or squamous-cell carcinoma, in the last five years. Compared with those in the placebo group, the patients taking a daily 500-milligram oral dose of vitamin B3 had a 23 percent lower rate of developing new nonmelanoma skin cancers over a one-year period. They also developed between 11 and 20 percent fewer premalignant actinic keratoses. Still pack the sunscreen, but slip a bottle of vitamin B3 into your valise as well.
