New Research Suggests Vitamin B3 May Reduce Skin Cancer Risk
A recent study has highlighted the potential of a common vitamin in lowering the risk of skin cancer. Conducted by researchers and featured in JAMA Dermatology, the study indicates that nicotinamide, a form of vitamin B3, could significantly decrease the chances of developing several types of skin cancer.
The research reviewed health records from over 33,000 veterans collected between 1999 and 2024 from the Veterans Affairs department. Among the participants, about 12,287 individuals took 500 mg of nicotinamide twice a day for more than a month, while the remaining 21,479 did not use the supplement.
The results showed that those who consumed vitamin B3 experienced a overall reduction in skin cancer rates, with the risk of developing skin cancers such as basal cell carcinoma and squamous cell carcinoma dropping by approximately 14%.
Additionally, the study looked into the recurrence of skin cancer. It found that patients who began taking nicotinamide shortly after their first diagnosis had a 54% lower chance of the cancer returning. However, this protective effect was less pronounced for individuals who had multiple skin cancer diagnoses.
The findings suggest that early introduction of nicotinamide may be particularly beneficial, especially for those with a history of skin cancer. Patients who have undergone organ transplants saw some benefits but mainly when the supplement was taken early on.
The lead researchers concluded that vitamin B3 can help lower skin cancer risks, especially when started right after the first diagnosis. Dr. Lee Wheless, a co-researcher from Vanderbilt University Medical Center, mentioned in a recent podcast that these findings have influenced his perspective on preventive treatment. While he advises caution before beginning nicotinamide right after a diagnosis, he believes taking it early could make a significant difference.
As the research continues, it offers hope for better prevention strategies against skin cancer, emphasizing the importance of early intervention.
