Beta-carotene is a natural source of vitamin A. The majority of people in Western countries obtain sufficient Vitamin A from their diet. However, Beta carotene may be prescribed for people with certain conditions that increase the need for the vitamin- for example, cystic fibrosis, chronic illness and intestinal mal absorption. Beta carotene is found in yellow fruit, dark green leafy vegetables, carrots, yams, alfalfa and barley grass.
Beta-carotene is an important source of free radical fighter for various forms of cancer as it protects against ultraviolet damage and enhances the immune system. It carries many of the same functions as Vitamin A. The liver and the intestinal wall obtain useable vitamin A by converting beta-carotene.
Beta carotene is not an essential nutrient; therefore it is not possible to develop a true deficiency. However, alcohol consumption decreases beta-carotene in the liver and people with hypothyroidism and diabetes may have trouble converting beta-carotene into vitamin A.
The effect of beta-carotene on pregnant woman has not been studied. However, no problems with fertility or pregnancy have been reported in women taking upto 30 mg of beta carotene a day. Beta carotene may cause complications in patients with liver disease or kidney problems and those taking cholestyramine, neomycin and Vitamin E.
