chia seed and Reduced Systolic Blood Pressure

Research synthesisLow evidenceSmall effect3 studies · 1 beneficial · 2 neutral · 0 harmful

Across 3 studies, 1 reported a beneficial small effect on systolic blood pressure, while 2 found no significant effect. The only statistically significant finding came from a meta-analysis (2025) with a small effect size (g = -0.119). Effects were predominantly small across studies, and the median study duration was 84 days (reported by only 1 study).

Caveats: Evidence base is small (only 3 studies) — conclusions should be considered preliminary. Many of the included studies did not reach statistical significance — effect may be smaller than the predominant direction suggests.
