Journal of dietary supplements (2024) · Meta analysis · n=4838
Products with berberine alone had less robust effects on TC (MD -12.08 mg/dL [95%CI: -21.79 to -2.37]), LDL (MD -9.26 mg/dL [95%CI: -20.31 to 1.78]), and HDL (MD 1.38 mg/dL [95%CI: -1.27 to 4.03]) but TG effects were similar (MD -17.40 mg/dL [95%CI: -32.57 to -2.23]).
Based on meta-analysis of 1086 participants showing significant reductions in CRP and TNF-α, but no effect on IL-6. High heterogeneity between studies limits confidence.
Based on RCT showing 16.77% reduction with 3mg and 26.46% reduction with 10mg monacolin K. Conservative effectiveness scaling due to limited dose-response data and variable study quality noted in meta-analyses.
