Blue-green algae are one of the most nutrient dense, protein- and vitamin-packed foods available. Considered a superfood, the spirulina variety comes in capsule, tablet, powder, or oil forms. Algae products are harvested from Upper Klamath Lake in southern Oregon. The algae are chilled, frozen, and dried at low temperatures before being processed into the desired form. As both a food and medicine, algae have provided sustenance for centuries. Humans have consumed both the spirulina and chlorella varieties since the Aztec civilization of the 14th century. This powerful energy booster is a popular choice for people seeking to lose weight.

1. Protein

The amino acids present in spirulina make it a rich source of protein. Researchers suggest that amino acids make up 62 percent of spirulina algae. Although it is used as a diet supplement, a large quantity would be needed to match protein sources like nuts, whole grains, and meat. Your body uses protein to build and repair tissues and to make chemicals like hormones and enzymes. Proper protein consumption is vital for keeping healthy skin, blood, bones, muscles, and cartilage.
