Effect of pycnogenol supplementation on blood pressure: A systematic review and meta-analysis of clinical trials
Phytotherapy research : PTR (2020) · Meta analysis · n=922
Pooled analysis suggested that pycnogenol supplementation can reduced systolic blood pressure (SBP) of (-3.22 mmHg; 95% CI [-5.52, -0.92]) and diastolic blood pressure (DBP; -1.91 mmHg; 95% CI [-3.64, -0.18]).
Based on multiple meta-analyses showing EPA-dominant formulas >1g/day most effective. Effects plateau around 2-2.5g. Adjunctive use with antidepressants shows better outcomes than monotherapy.
Based on meta-analyses showing modest reductions in systolic (-3.22 mmHg) and diastolic (-1.91 mmHg) blood pressure. Effects are clinically small and studies show heterogeneity.
