Spirulina
Blue-green algae rich in protein, B vitamins, & phycocyanin; antioxidant & exercise recovery signals in several trials.
Evidence last reviewed: 04 Apr 2026
Spirulina is a nutrient-dense blue-green algae that may support exercise recovery and reduce oxidative stress. However, its benefits are modest and should be approached with caution due to potential contamination risks.
Contamination risk (heavy metals, cyanotoxins) from non-certified sources — always buy third-party tested
Iodine content may affect thyroid function — caution with thyroid disorders or thyroid medication
Mild blood-thinning activity — caution when combined with anticoagulants
Summarized study outcomes with population, design, grade, and effect data.
Research indicates that spirulina may improve exercise performance and reduce oxidative stress in both trained and untrained individuals, though the effects are generally modest. The evidence is moderate, with some concerns about contamination and individual variability in response.
