(WEBMD) — Can popping vitamin A supplements help stave off melanoma, the potentially fatal form of skin cancer?

Maybe, a new study suggests.

But even the researchers caution that it is too soon to make any recommendations about taking extra vitamin A to reduce risk for melanoma. Vitamin A can be toxic in high doses.

Researchers analyzed melanoma risk among 69,635 people. Study participants were aged 62 on average. The researchers found that those participants who took vitamin A via supplements were about 40% less likely to develop melanoma than those who did not.

Only the supplements lowered melanoma risk, not vitamin A from food.
