Key result
Ingestion of green coffee bean extract significantly increased the reactive hyperemia ratio compared to placebo (2.49 vs 1.38, p<0.05) after 4 months in healthy males, indicating improved vasoreactivity.

Absolute Event Rate: 2.49% vs 1.38%
p-value: p=<0.05
Green coffee bean extract ingestion for 4 months improved vasoreactivity and decreased plasma total homocysteine levels in healthy males with reduced vasodilation responses.
Suzuki et al. (2004) conducted an RCT in Healthy with reduced vasodilation responses (n=20). Green coffee bean extract (GCE) vs. Placebo drink was evaluated on Reactive hyperemia ratio (RHR) at 4 months (p=<0.05). Ingestion of green coffee bean extract significantly increased the reactive hyperemia ratio compared to placebo (2.49 vs 1.38, p<0.05) after 4 months in healthy males, indicating improved vasoreactivity.
