Spirulina is an exceptional food and an incredible source of concentrated, non-toxic, absorbable nutrients. It is a highly beneficial substitute for protein powders. The protein in spirulina contains all eight essential amino acids, making it a complete protein. Spirulina (a blue green algae) also contains vitamins A, B1, B2, B6, B12, E, and K. In addition, spirulina provides minerals, trace minerals, cell salts, phytonutrients and enzymes, as well as an abundance of chlorophyll and other beneficial pigments. Spirulina is 65% complete protein, making it the world's highest known source! Plus, HealthForce’s spirulina is dried at low temperatures (enzyme active) versus a heated protein, so protein utilization is maximized.
