Spirulin Extract

Spirulina extract is a natural colorant derived from spirulina, a type of blue-green algae. The algae are grown in controlled environments and then processed to isolate the phycocyanin pigment, which gives the extract its vibrant blue color.

Manufacturers use spirulina extract primarily as a natural blue food coloring. It is often found in confectionery, baked goods, dairy products, and beverages where a bright blue hue is desired without using artificial dyes.

Spirulina extract is generally recognized as safe (GRAS) by the FDA for use as a food colorant. It is considered safe at typical consumption levels. International bodies like EFSA have also evaluated phycocyanin, the main component of spirulina extract, and found it safe for use. Research suggests spirulina may have antioxidant properties, but more studies are needed to confirm significant health benefits from typical food-level exposure.
