About Spirulina

Spirulina is a blue-green microalgae that is one of the most nutrient-dense foods on Earth. Composed of up to 70% complete protein by weight, it contains all essential amino acids, along with B vitamins, iron, and the powerful antioxidant phycocyanin (which gives it its blue-green color). NASA has studied it as a food source for astronauts. It has demonstrated immune-supporting, antioxidant, and cholesterol-lowering effects in clinical trials.
