Spirulina
Overview
Spirulina (Arthrospira platensis) is a cyanobacterium with ~60–70% complete protein, phycocyanin (antioxidant), GLA, beta-carotene, and iron. A meta-analysis of 7 studies confirmed significant weight and MUAC improvement in malnourished children. Adult evidence supports lipid lowering, blood pressure reduction, and antidiabetic effects. Critical: contains pseudovitamin B12 (inactive) — not a reliable B12 source for vegans. Risk of heavy metal and cyanotoxin contamination — only certified GMP-tested products. Contraindicated in phenylketonuria. Caution in autoimmune conditions.
