Vitamin 'better than sunscreen'
Email Printer friendly version Normal font Large font November 19, 2008 - 10:56AM
A vitamin found in meats, nuts, grains and cereals might be more effective than sunscreen in preventing skin cancer, new research has found.
Nicotinamide, or vitamin B3, prevents damage from both UVA and UVB radiation by protecting the immune system, and could be taken in tablet form or added to sunscreen, Associate Professor Diona Damian of the University of Sydney says.
Sunscreens provide good protection against UVB rays, which cause sunburn and skin cancer, but the products are less effective in protecting against UVA, which can also cause skin cancer.
"UV radiation in sunlight suppresses the skin's immune system and makes it more susceptible to skin cancer," she said.
"Our research found that nicotinamide [vitamin B3] can prevent the immunosuppressive effects of UV by energising cells so they maintain their immunity."
Tests using the water-soluble vitamin offered equally strong protection against both UVA and UVB in both lotion and tablet form, according to tests on volunteers, Professor Damian said.
"Nicotinamide is well tolerated, so could also be taken orally as a supplement, particularly by people who have a higher susceptibility to skin cancer," she said.
It is also relatively cheap to produce so it could potentially be incorporated into sunscreen to boost its effectiveness against UVA, she added.
The research was also looking to determine whether the vitamin could be used to treat sunspots, common lesions that sometimes progress to skin cancer.

Thank you for sharing, LizaA.
Topical application of B3/nicotinamide/niacinamide is shown in studies to strengthen skin barrier, treat hyperpigmentation and possibly reduce wrinkles. It's very interesting to learn that it may also protect against sun rays.
What a great vitamin! |

| Yep thanks for posting, I think that anyone who is serious about keeping the healthiest skin they can should be using a sunscreen and taking a good multivit/min that should definitely include those to make sure they have all bases covered (no pun intended!). |

| while it is great, i dont think it can replace sunscreens. You still HAVE TO ABSOLUTELY put some sunscreen on before u go out. these vitamins strengthen the protection but doesnt do the job like sunscreen does |
