Nicotinamide (vitamin B3) has been shown to have protective effects against damage caused by UV radiation and to reduce the rate of new premalignant actinic keratosis and non-melanoma skin cancers. Here are the numbers from the Study published in the New England Journal of Medicine:
- 386 participants who had had at least two non-melanoma skin cancers in the previous 5 years received 500 mg of nicotinamide twice daily or placebo for 12 months.
- The number of actinic keratoses at 4 months was 29% lower among those who received 500 mg of nicotinamide administered orally once daily and 35% lower among those who received 500 mg of nicotinamide twice daily than among those who received placebo.
- Patients taking nicotinamide twice daily experienced a 25% decrease in non-melanoma skin cancer rates.
AboutSkin now has nicotinamide available for your convenience. It retails for $29.50 + tax for 100 tablets. We advise taking one table twice daily to maximize the health benefits.
