Spirulina powder

Spirulina is a blue-green algae, a type of cyanobacteria, that grows in both fresh and saltwater. It is cultivated and harvested, then typically dried and milled into a powder. This powder is often used as a food ingredient or dietary supplement.

Spirulina powder is primarily used as a natural colourant, imparting a vibrant green hue to foods and drinks. It is also added for its nutritional profile, contributing protein and micronutrients. It is commonly found in dietary supplements, smoothies, and 'superfood' blends.

Spirulina is authorised as a food ingredient in Great Britain. It is not typically classified as a food additive under assimilated Regulation (EC) No 1333/2008. The European Food Safety Authority (EFSA) has evaluated spirulina and concluded that it is safe for consumption under specific conditions of use, particularly concerning potential contamination with microcystins. At typical intake levels found in foods, it is generally considered safe. Some studies suggest potential benefits related to its antioxidant and anti-inflammatory properties, but more robust research is needed to confirm these effects.
