Powerful antioxidant and Vitamin A precursor *Beta carotene is a precursor to vitamin A. It supports the body's defense system, enhances visual acuity, and quenches free radicals. Beta carotene's powerful antioxidant potential supports healthy tissues and DNA integrity. It is virtually nontoxic; the body converts beta carotene to vitamin A as needed. Beta carotene is one of the major dietary antioxidants, offering the body optimal nutritional support through free radical scavenger activity and provitamin A activity.
