Spirulina (Arthrospira)
Blue-green algae with 60-70% complete protein and unique phycocyanin antioxidant — lowers cholesterol, blood pressure, and blood sugar.
Spirulina is a blue-green algae (cyanobacteria) that has been consumed for centuries and is considered one of the most nutrient-dense foods on Earth. It contains 60-70% complete protein, B vitamins, iron, and unique compounds like phycocyanin (the blue pigment with potent antioxidant properties). Research shows benefits for cholesterol, blood pressure, blood sugar, and allergies. It's also a sustainable protein source.

“Further research is needed to validate these effects and ensure their safety in MASLD management.”
Pinto-Leite M et al. • Nutrients (2025)
“Conclusions: Further randomised trials are needed to better assess the potential of these supplements as adjuvants for the control of cardiovascular risk factors.”
Casas-Agustench P et al. • Journal of human nutrition and dietetics : the official journal of the British Dietetic Association (2025)
“Consuming over 3 g/day of whole edible algae, especially Spirulina, for at least 12 weeks significantly lowers BP, particularly in those with elevated levels.”
Bayo Jimenez MT et al. • International journal of molecular sciences (2025)
“Despite generally favorable results, the studies varied considerably in design and quality; nonetheless, herbal extracts represent a prominent category of natural interventions in AD and MCI, underscoring the need for further large-scale, high-quality clinical trials to confirm their therapeutic potential.”
Weiner JD et al. • Lupus science & medicine (2025)
“We identified 227 herbal supplements with immunostimulatory properties, of which 15 were most strongly supported by the evidence.”
