Prevention and maintenance are DIFFERENT doses and are often conflated. Preventing the first onset of acute pouchitis used 900 billion CFU/day (1 sachet). Maintaining remission in established chronic or refractory pouchitis — where the effect size is largest — used 6 g/day, which at 5 x 10^11 viable bacteria per gram is about 3 trillion CFU/day, in both maintenance trials. As a ulcerative colitis add-on, 3.6 trillion CFU daily; the active-UC induction trial went highest at 3.6 trillion CFU TWICE daily (7.2 trillion/day), and the paediatric trial lowest at 450 billion/day weight-based

Clinical Efficacy of Curcumin, Resveratrol, Silymarin, and Berberine on Cardio-Metabolic Risk Factors Among Patients With Type 2 Diabetes Mellitus: A Systemic Review and Bayesian Network Meta-Analysis
Phytotherapy research : PTR (2025) · Meta analysis · n=1337
For HbA1c, silymarin was more effective than resveratrol (MD -2.08, 95%Cl -3.50 to -0.72) (P < 0.05).

In addition, the non-linear analysis showed a significant lowering effect of berberine/barberry on IL-6 and TNF-α levels in doses <1000 mg/day and less than 5 weeks of intervention.

The 1,000 mg point is a placebo-controlled trial of berberine 1.0 g daily for 3 months in 116 people with type 2 diabetes, where HbA1c fell from 7.5% to 6.6% and fasting glucose fell more than on placebo (PMID 18397984). The 1,500 mg point is two trials of 500 mg three times daily: one in 36 people with new type 2 diabetes where glucose fell with no significant difference from metformin in this small pilot, with transient stomach side effects in 34.5% (PMID 18442638), and a placebo-controlled pilot in 34 people with prediabetes where HbA1c fell from 6.40% to 5.43% (PMID 37679692). No trial compared doses, so the curve is flat between them and no optimal dose is set. Lower doses were not tested for glucose in any cited trial.
