  • Low evidence3 studies

    Across 3 studies (2 systematic reviews/meta-analyses and 1 meta-analysis), 2 reported beneficial small effects of spirulina supplementation on reduced body weight, with statistically significant reductions observed in overweight and obese adults and general adult populations (e.g., weight loss of -1.78 kg, g = -0.30). One neutral finding came from a study in children and adolescents, which found no statistically significant effect. No consistent dose or form data were reported across studies.
