Spirulina (Arthrospira platensis) is a blue-green alga specie, rich in essential nutrients, including minerals (iron, potassium, magnesium), proteins, vitamins (especially vitamin B12), provitamin A (B-carotene), fatty acids, phenolic acids, tocophenols and more. Two components were recently recognized as playing a key role in spirulina's function: Phycocyanin, a pigment belonging to a group of water-soluble proteins called “phycobiliproteins,” and calcium-spirulan, a polysaccharide unique to spirulina containing both sulfur and calcium. Our spirulina extract is obtained by a proprietary process to achieve higher concentration of polysaccharides and phycobiliproteins.
