Not superior to placebo in recent trials
Based on meta-analyses showing FPG reduction of 0.59-0.82 mmol/L and HbA1c reduction of 0.63%. Studies primarily used berberine HCl with low bioavailability. Effects require divided doses and may take 8-12 weeks.
Mixed evidence from meta-analyses. Some show significant improvement in maximum urinary flow rate vs placebo, while others show no clinically meaningful improvement. Hexanic lipidosterolic extracts (like Permixon) showed most consistent results. Effectiveness is conservative due to conflicting study outcomes.
