Potential interaction under clinical review.
Not graded yet, under clinical review. Precaution meanwhile: Do not add red yeast rice to lipid-lowering or high-dose nicotinic acid without clinician review. The same interaction is not established for ordinary nutritional niacin or nicotinamide. Assess the actual product, form and dose. Pause optional red yeast rice and non-prescribed niacin and seek prompt assessment for unexplained muscle pain, weakness or liver symptoms. Dark urine, marked weakness or significant illness needs assessment today, with emergency help for severe deterioration. Do not stop prescribed lipid treatment yourself. Your clinician should decide whether blood tests are needed.

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.
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.
