Nicotinamide (Vitamin B3) and Skin Cancer Prevention: What the Latest Study Reveals
If you’ve ever had a skin cancer diagnosis—or know someone who has—you’ll want to hear this. A groundbreaking 2025 study involving over 33,000 U.S. veterans has confirmed what dermatologists have long suspected: nicotinamide, a form of vitamin B3, can significantly reduce the risk of developing new skin cancers.
🔬 What the Study Found
Researchers tracked veterans who took 500 mg of nicotinamide twice daily for at least 30 days. The results were striking:
• 14% overall reduction in new skin cancers
• 54% reduction in recurrence when started after a first diagnosis
• Especially effective against cutaneous squamous cell carcinoma (CSCC)
Unlike niacin, nicotinamide doesn’t cause flushing. It’s well tolerated, inexpensive, and widely available. Its protective effects stem from its ability to enhance DNA repair and reduce UV-induced immune suppression, making it a powerful ally in skin cancer prevention.
🧠 Why This Matters
If you or a loved one has had a skin cancer scare, nicotinamide offers a safe, affordable, and science-backed way to reduce future risk. It’s not a replacement for sunscreen or regular checkups—but it’s a smart addition to your prevention toolkit.
