    Test Description

    Beta Carotene

    Beta-carotene is a lipid soluble vitamin, or carotenoid. It is also known as pro-vitamin A. It is a very large molecule that is converted to vitamin A in a ratio of 1:2 beta carotene to vitamin A when it metabolized in the liver. The body will convert beta carotene to vitamin A based on its needs. This conversion needs a proper functioning thyroid and the patient cannot be a diabetic. It is not unusual to find an elevated beta carotene and low vitamin A in these patients. Beta carotene is a very strong antioxidant especially in lipid membranes. It is also important in proper eye health. There is no toxic level for beta carotene. If taken in an excessive amount, the skin, especially on the hands, may turn yellow.
