This new product is packed with carotenes: beta carotene, alpha carotene, cryptoxanthin, zeaxanthin, and lutein. The body makes its own vitamin A from these bioavailable forms, but only as much as it needs. So no worries of toxic buildup that you may have read about-that only applies to high intake of the retinoid form of vitamin A. Carotenes support the body in maintaining good vision, healthy bones, and a vibrant immune system. Plus, they are powerful antioxidants. What's not to love?
