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 showing 9.29 mg/dl LDL reduction with 107-856 mg/d EGCG. Optimal cardiovascular benefits observed at 400-500 mg/day. Take with food to reduce GI side effects.
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.
