Spirulina is the richest beta carotene food, with a full spectrum of ten mixed carotenoids. About half are orange carotenes: alpha, beta and gamma and half are yellow xanthophylls. They work synergistically at different sites in our body to enhance antioxidant protection. Twenty years of research proves eating beta carotene rich fruits and vegetables gives us real anti-cancer protection. Synthetic beta carotene has not always shown these benefits. Research in Israel showed natural beta carotene from algae was far more effective. Natural is better assimilated and contains the key 9-cis isomer, lacking in synthetic. As suspected, natural carotenoids in algae and vegetables have the most antioxidant and anti-fast growing cells power. Spirulina is an ideal anti-aging food; concentrated nutrient value, easily digested and loaded with antioxidants. Beta carotene is good for healthy eyes and vision. Spirulina beta carotene is ten times more concentrated than carrots. Iron is essential to build a strong system, yet is the most common mineral deficiency. Spirulina is rich in iron, magnesium and trace minerals, and is easier to absorb than iron supplements. Spirulina is the highest source of B-12, essential for healthy nerves and tissue, especially for vegetarians.
