A meta-analysis found no significant difference in response rates between the two treatments (risk ratio [RR] = 0.96, 95% CI: 0.78-1.18) or dropout rates (RR = 1.08, 95% CI: 0.62-1.88).
S-Adenosylmethionine (SAMe) for Liver Health: A Systematic Review
Nutrients (2024) · Systematic review · n=15
The most common doses were SAMe 1000 mg or 1200 mg per day with or without another treatment or natural supplement.
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.
Meta-analysis of 656 patients showed small effect size (SMD -0.17) corresponding to only 0.4cm improvement on 10cm pain scale. Effect is modest and barely reaches statistical significance threshold.
