Beta carotene is a precursor to vitamin A. It acts as a powerful antioxidant that helps protect cells from damage caused by free radicals. Additionally, it plays an important role in maintaining healthy vision, immune function and skin health.
Beta carotene is type of carotenoid that is found in many orange and yellow fruits and vegetables. Beta carotene itself is not considered a vitamin, but it is converted into vitamin A when needed by the body.
Health benefits and role of beta carotene in the body
Antioxidant properties. Beta carotene is a powerful antioxidant that helps protect the body’s cells from oxidative stress and damage caused by harmful molecules called free radicals. This antioxidant activity can help reduce the risk of chronic diseases and slow down the aging process (1).
