Fenugreek Seed and Reduced Diastolic Blood Pressure

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

Across 3 studies, only 1 reported a beneficial small effect on diastolic blood pressure, while 2 found neutral effects. The single beneficial result came from a small trial in Alzheimer's patients using 5 cc of fenugreek seed extract daily for 120 days. The median study duration was 88 days, suggesting effects may require several weeks to emerge, but the evidence is too sparse to confirm a reliable benefit.

  • Studied populations: Alzheimer's disease patients with mild-to-moderate memory deficit

Caveats: Evidence base is small (only 3 studies) — conclusions should be considered preliminary. Only one statistically significant finding was observed, and it came from a small clinical population; the higher-quality meta-analysis (evidence score 6) found no significant effect on DBP. Many of the included studies did not reach statistical significance — effect may be smaller than the predominant direction suggests.
