Bluebonnet’s Beta-Carotene 25,000 IU Vcaps contain a branded natural beta-carotene/carotenoid mix called Betatene, derived from 100% natural Dunaliella salina, which is grown in the crystal clean lakes of Whyalla, Australia. This special patented carotenoid mix provides a balanced blend of potent carotene antioxidants as they exist in nature: alpha-carotene (480 mcg), beta-carotene/vitamin A (25,000 IU), cryptoxanthin (110 mcg), zeaxanthin (90 mcg) and lutein (70 mcg) in easy-to-swallow vegetable capsules for maximum assimilation and absorption.
