DENVER -- The Denver area averages 300 sunny days a year. If that has you worried about getting skin cancer, you might want to up your intake of vitamin A.

New research suggests people taking vitamin A supplements were 60 percent less likely to develop melanoma.

Denver dermatologist Dr. James DeVito said vitamin A’s benefits are well known.

“We use it because it has a polishing effect on the skin, it can smooth out the skin, it helps with fine lines and wrinkles, it also helps with acne,” DeVito said.

But for the anti-cancer effect it’s not topical vitamin A, it’s internal supplements that make the difference. So how much should you take?

“The recommended daily allowance for men and women is between 700 and 900 micrograms per day,” DeVito said.

You can, however, have too much of a good thing.

“Too much vitamin A can cause vision problems, it can also cause bone loss, osteoporosis,” said DeVito.

The study also said vitamin A in food didn’t contribute to the benefit, it was just supplements. DeVito suggested talking to your doctor about what daily amount is right for you.
