Spirulina

Spirulina is a type of blue-green algae, a single-celled organism that grows in both fresh and saltwater. It is cultivated and harvested, then dried and processed into a powder or tablet form for use as a food ingredient.

Spirulina is often added to foods and beverages for its vibrant blue-green color and its nutritional profile. It is commonly found in smoothies, juices, energy bars, and as a natural food coloring in various products.

Spirulina is generally recognized as safe (GRAS) by the FDA for use as a food ingredient. It is a source of protein, vitamins, and minerals. While some studies suggest potential health benefits, more research is needed to confirm these effects. The WHO has noted its potential as a low-cost food supplement.
