Beta carotene is a red-orange pigment found in plants and fruits, especially carrots and colorful vegetables. Beta-carotene and other carotenoids provide approximately 50% of the vitamin A needed in the American diet. Beta-carotene can be found in fruits, vegetables, and whole grains. It can also be made in a laboratory.
Beta-carotene is used to decrease asthma symptoms caused by exercise; to prevent certain cancers, heart disease, cataracts, and age related macular degeneration (AMD); and to treat AIDS, alcoholism, Alzheimer’s disease, depression, epilepsy, headache, heartburn, high blood pressure, infertility, Parkinson’s disease, rheumatoid arthritis, schizophrenia, and skin disorders including psoriasis and vitiligo.
