Beta carotene is a type of carotenoid, a pigment found in plants that gives them their intense color. It is orange-yellow and is found in yellow, orange, and red foods. Beta-carotene transforms into vitamin A In the body. Vitamin A supports healthy vision, immunity, and many other vital functions.

Beta carotene is also an antioxidant, and can slow cell damage from waste materials called free radicals.  Free radicals are created in the body through normal body processes and outside environmental stress. When free radicals aren't effectively removed from the body, oxidative stress can result.

Oxidative stress may factor into several types of health conditions, including the following:

Cancer: The growth of malignant cells in the body

Cardiovascular disease: Includes conditions that affect the heart and the blood vessels

Diabetes: A chronic disease in which the pancreas doesn't produce insulin to regulate blood sugar

Inflammatory diseases: Those caused by persistent inflammation in the body

Infectious diseases: Such as an infection with a bacterium

Neurodegenerative diseases: Affect the brain and nerves, and include dementia, Alzheimer's, and Parkinson's.

Antioxidants like beta carotene may help remove free radicals, thereby preventing the conditions free radicals may cause.
