Summary

Nicotinamide, a vitamin B3 form, may prevent many skin cancers.
Study suggests a 14% lower risk of new skin cancers with supplementation.
Significant 54% risk reduction in additional cancers if started promptly.

Recent research highlights a potential breakthrough in skin cancer prevention, suggesting that a common vitamin supplement may dramatically reduce cases of the world's most diagnosed cancer. Nicotinamide, a readily available form of vitamin B3, has shown promising results in large-scale studies.

The new evidence indicates that daily intake of nicotinamide can lower the risk of developing new skin cancers by 14%. This benefit is particularly significant, with a 54% reduction in additional cancer development when supplementation begins promptly after an initial diagnosis. The supplement works by enhancing the skin's repair mechanisms and immune response to UV damage.

While nicotinamide offers a hopeful addition to prevention strategies, it does not replace essential measures like sun avoidance and sunscreen use. However, its low cost and safety profile make it an attractive secondary prevention tool, especially for individuals with a history of skin cancer. Further research is ongoing to explore its long-term effects and efficacy in diverse populations.
