Spirulina powder comes from a blue-green freshwater algae. Suitable for vegans and dried at a low temperature. Nothing added or removed. Spirulina is rich in nutritional values. It contains an abundance of valuable nutrients, including proteins (it is actually considered a complete source of protein, making it a favorite with vegetarians). Features fibers and chlorophyll (the natural plant pigment that is responsible for the striking color and with which plants can absorb energy from light). It also contains calcium, vitamins (vitamins B12 and K) and minerals (such as magnesium, potassium, thiamin, riboflavin, niacin, iron, copper and manganese).
