The Role of Chlorella and Spirulina as Adjuvants of Cardiovascular Risk Factor Control: A Systematic Review and Meta-Analysis of Randomised Controlled Trials
Nutrients (2025) · Meta analysis · n=12
On the other hand, Spirulina intake led to a significant reduction in diastolic BP (-0.42, 95% CI: -0.81 to -0.02, p = 0.04) but did not significantly affect lipemia indexes, despite a trend toward a reduction in total cholesterol (-0.17, 95% CI: -0.39 to 0.06, p = 0.15).
Edible Algae Reduce Blood Pressure in Humans: A Systematic Review and Meta-Analysis of Randomised Controlled Trials
Journal of human nutrition and dietetics : the official journal of the British Dietetic Association (2025) · Meta analysis · n=1583
Edible algae intake significantly reduced systolic BP (SBP: -2.05 mmHg; 95% CI: -3.80, -0.31; p = 0.022) and diastolic BP (DBP: -1.87 mmHg; 95% CI: -3.10, -0.64; p = 0.001).
Evidence primarily from cancer adjuvant studies showing immune modulation. One RCT (n=141) showed reduced treatment-related adverse events in cancer patients. Most evidence is preclinical or from systematic reviews without specific dose-response data.
Based on multiple meta-analyses showing dose-dependent effects. LDL reduction of ~33mg/dL and triglycerides ~39mg/dL reported. Effects appear to plateau above 8-10g daily.
AI-estimated from published studies. Interpret as directional guidance.
Spirulina has a higher evidence score (7/10 vs 3.5/10) and wins in 2 of 3 categories.
For support immune system, Maitake has a higher relevance score (75 vs 70).
