Spirulina is a blue-green microalgae that contains natural proteins, as well as other nutrients such as vitamins, minerals and GLA (gamma-linolenic acid).

Blue-green algae is considered a "supergreen" because it contains many supporting nutrients. One of these nutrients is a powerful plant protein called phycocyanin, which is the pigment that gives spirulina its blue-green color.

Phycocyanin may have antioxidant properties and may also improve immune function. Spirulina also contains chlorophyll, which can help promote red blood cell production and protect the body from toxins.

Spirulina is rich in beta-carotene (vitamin A) and vitamin B-12, and contains natural protein and GLA (gamma-linolenic acid), a popular fatty acid with many health benefits. In addition, spirulina contains naturally occurring minerals, trace elements, cell salts, amino acids and enzymes.
