Fresh spirulina is a nutrient-rich food that provides protein, iron and other naturally occurring nutrients. It can be one part of a varied eating pattern, alongside vegetables, fruit, whole grains, legumes and other protein sources.
Research on spirulina covers nutrition, metabolic markers and other health-related topics. The strength of that evidence varies: some findings come from laboratory or animal studies, while human trials are often small and use different products and doses.
SPRU does not present spirulina as a cure or a replacement for medical care. Research pages on this site are educational and should be read with their study limitations in mind.
