Skin cancer is the most common form of cancer in the United States, with millions of new cases diagnosed every year. A recent large-scale study of over 33,000 veterans has brought encouraging news: vitamin B3 (nicotinamide) supplementation may significantly reduce the risk of developing non-melanoma skin cancers and lower the chance of recurrence. At Doral Healthcare & Wellness, we believe in empowering our patients with the latest research so you can make informed decisions about your health.
What is Nicotinamide?
Nicotinamide is a form of vitamin B3, a water-soluble nutrient naturally found in foods such as meat, fish, nuts, seeds, and green vegetables. Unlike niacin, another form of vitamin B3, nicotinamide does not cause flushing or unpleasant side effects at therapeutic doses.
This vitamin plays a key role in DNA repair, immune system support, and skin cell protection against ultraviolet (UV) damage — which makes it particularly valuable in dermatology and cancer prevention research.
Key Findings from the Study
Participants who took 500 mg of nicotinamide twice daily for at least 30 days saw a 14% overall lower risk of developing non-melanoma skin cancer.
Among patients who had already experienced their first skin cancer, risk of recurrence dropped by more than 50%.
The supplement was generally well tolerated, with no major side effects reported in the trial.
Why This Matters for Patients
These findings are especially significant for individuals at high risk of skin cancer, including those with:
A history of basal cell or squamous cell carcinoma.
Excessive sun exposure or fair skin types.
Weakened immune systems.
While nicotinamide is not a replacement for sunscreen, regular dermatology check-ups, or healthy lifestyle choices, it may become an affordable, low-risk preventive option to discuss with your healthcare provider.
Practical Takeaways
Supplementation dosage used in the study: 500 mg twice daily.
Prevention, not cure: Nicotinamide reduces risk but does not eliminate it.
Medical guidance is essential: Always speak to your doctor before starting any supplement, especially if you have other conditions or take medications.
