Spirulina and Reduced Diastolic Blood Pressure

Research synthesisModerate evidenceModerate effect3 studies · 3 beneficial · 0 neutral · 0 harmful

Across 3 studies, all 3 reported beneficial moderate-sized effects of spirulina supplementation on reducing diastolic blood pressure. The evidence consistently shows a statistically significant reduction, with meta-analyses reporting a weighted mean difference of approximately -2.84 to -3.09 mmHg. Studies primarily included overweight and obese adults or general adults over 18 years, though dose ranges and study durations were not consistently reported.

  • Studied populations: overweight and obese adults; adults over 18 years

Caveats: Evidence base is small (only 3 studies) — conclusions should be considered preliminary. Available evidence is overwhelmingly positive — clinical literature in this area is subject to publication bias (null-result studies are less likely to be published or indexed). Study durations and specific doses were not consistently reported across studies.
