Vitamin B3 for skin cancer prevention


Clinical trials performed here in Sydney of nicotinamide in patients with previous non-melanoma skin cancers (basal cell carcinoma and squamous cell carcinoma) showed a 23% reduction in these skin cancers.

It is important to take nicotinamide and not a different form of vitamin B3 called nicotinic acid (niacin) which can have unpleasant side effects such as headache, flushing and low blood pressure. These side effects do not occur with nicotinamide.

Of course, it is still essential to protect your skin and continue regular skin checks, especially if you have a history of skin cancer.

Talk to your dermatologist to see if Nicotinamide supplementation may be right for you.
