Impact of Berberine or Berberine Combination Products on Lipoprotein, Triglyceride and Biological Safety Marker Concentrations in Patients with Hyperlipidemia: A Systematic Review and Meta-Analysis
Journal of dietary supplements (2024) · Meta analysis · n=4838
Meta-analysis of 41 randomized trials (4,838 patients) of berberine products, alone or combined with other nutraceuticals such as red yeast rice, for 8-18 weeks.
The points come from one dose-comparison trial, BENDIP (PMID 18473286): 165 people with diabetic polyneuropathy randomised to 300 mg, 600 mg or placebo for 6 weeks, 133 in the ITT analysis. The Neuropathy Symptom Score differed between groups in the per-protocol analysis (p=0.033) but only narrowly missed significance by intention to treat (p=0.055), and the Total Symptom Score did not differ. Improvement was more pronounced at 600 mg, and both doses were well tolerated. No higher dose was compared, so no optimal dose can be given. The minimum effective dose comes from a separate 3-week trial of 400 mg a day in 40 inpatients, where the neuropathy score and pain improved against placebo (PMID 15726875). At 300 mg a day for 24 months, a trial in 67 people with type 1 diabetes found no effect on peripheral nerve function (PMID 22446172).
Both points come from one 8-week randomised trial in 105 people with mild high cholesterol (PMID 37375586): LDL fell by 16.77% on 3 mg of monacolin K and by 26.46% on 10 mg, on top of lifestyle change, and effectiveness is that percentage fall. The product also contained CoQ10, grape seed and olive leaf extracts, and no severe adverse events occurred. A separate 8-week trial of 200 mg red yeast rice with 2 mg monacolin K in 18 people lowered LDL more than diet alone (PMID 34587702). The 6 mg point was removed because no cited trial tested it, and no cited trial tested more than 10 mg.
