Protectamins® Multi-Carotene Antioxidant Complex Contains several antioxidants from the Carotene family, and the highest level of Alpha Carotene available, naturally extracted from red palm fruit. Why is Alpha Carotene Important? Studies show that Alpha Carotene has 10x the protective effect of Beta Carotene. Studies also show a mixture of carotenes taken together is more effective than the total effect of carotenes taken singly.
