How much beta-carotene should I take?

ANSWER

While there is a recommended dietary allowance (RDA) for vitamin A, there is no RDA for beta-carotene specifically. Studies have used dosages ranging between 15 and 180 milligrams a day.

However, high doses or long-term use may be dangerous, so talk to your doctor about it.
