"Now, a new study of nearly 34,000 veterans, finds this over-the-counter supplement is linked to a reduction in non-melanoma skin cancers among people who've already had skin cancer. The research was published in JAMA Dermatology. The biggest reduction was seen among people who began taking the supplement after being diagnosed with their first skin cancer."
"Researchers found those who took 500 mg of nicotinamide, also known as niacinamide, twice daily, for at least one month, had a 54% reduced risk of developing another skin cancer, compared to patients who did not take the supplement. Overall, the reduction in skin cancer risk, across all the participants, was about 14 percent. The reduction was seen in non-melanoma skin cancers, including basal cell carcinoma, which is the most common, and cutaneous squamous cell carcinoma."
"Evidence to support the potential benefits of B3 supplements to protect against skin cancer goes back a decade. The results of a randomized clinical trial in Australia published in 2015 that included 386 people with a history of non-melanoma skin cancers pointed to a reduced risk of new skin cancers. The findings led many doctors to recommend B3 supplements to their patients."
Nearly 34,000 veterans with prior skin cancer were analyzed for nicotinamide use and subsequent non-melanoma skin cancer risk. Patients who took 500 mg nicotinamide twice daily for at least one month had a 54% lower risk of developing another skin cancer if they began after their first skin cancer diagnosis. Across all participants, nicotinamide use was associated with about a 14% reduction in non-melanoma skin cancer risk. Risk reductions occurred for basal cell carcinoma and cutaneous squamous cell carcinoma, with the largest decrease seen in squamous cell cancers. Prior randomized trial evidence has already led many clinicians to recommend B3 supplements.
