Seventeen studies of confirmatory design (sample and effect sizes pre-specified) were mostly at moderate risk of bias.
Based on meta-analysis showing mean reductions of 5.39 mmHg systolic and 2.66 mmHg diastolic. Effects are modest and may not be clinically significant for all individuals. GI side effects increase notably above 6g.
Based on multiple meta-analyses showing pain reduction in osteoarthritis. Effects may vary significantly by extract standardization (AKBA content) and bioavailability enhancement. Studies primarily used 30-40% AKBA extracts.
