Spirulina is a blue-green micro-algae that grows in alkaline water. It is the world's healthiest food rich in beta carotene (10 times more concentrated than carrots) and phytonutrients. This tiny aquatic plant offers 60% all-vegetable protein (with all the essential amino acids), essential vitamins (high in Vit-B12 and Vit-B complex) and phytonutrients such as the antioxidant beta carotene, the rare essential fatty acid GLA, sulfolipids, glycolipids and polysaccharides. Its deep color comes from its rainbow of natural pigments: chlorophyll (green), phycocyanin (blue) and carotenoids (orange), that harvest solar energy. Spirulina is easy to be digested, so nutrients are absorbed quickly. Spirulina is the most extensively researched food microalgae, well documented in numerous books, journal articles, and periodicals. Many people use Spirulina in their own self-care strategy for more energy, nutritional insurance, weight management and cleansing. Athletes discover more endurance and strength. Seniors find better nutrient absorption.
