BetaCareAll is a unique formula, containing 25,000 IU of natural Beta Carotene (8330 IU Vitamin A) and other beneficial carotenoids. This blend of natural carotenoids comes from the sea plant, Dunaliella salina. Beta Carotene is converted to Vitamin A in the body. Vitamin A is essential to many body processes, including maintenance of healthy skin, mucous membranes, bones and teeth. Carotenoids, found in fruits and vegetables, are powerful antioxidants — preventing damage to cellular structures throughout the human body.
