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.
Meta-analysis showed modest 3.32 mg/dL reduction in fasting glucose. Effects were heavily influenced by small number of positive studies, with majority showing mixed results. Higher doses increase GI side effects.
