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 meta-analysis of 124 RCTs showing 6-12% LDL reduction at standard doses. Conservative effectiveness scale with optimal intake around 2g/day. No significant effects on HDL or triglycerides observed.
Based on meta-analyses showing modest reductions in systolic (-3.22 mmHg) and diastolic (-1.91 mmHg) blood pressure. Evidence quality varies across studies and effect sizes are relatively small.
