Red yeast rice is one of the best-studied natural cholesterol-lowering supplements. The CCSPS trial (Lu et al., 2008) remains the largest cardiovascular outcomes study of any supplement, demonstrating significant reductions in cardiac events and mortality. Li et al. (2014) conducted a comprehensive meta-analysis confirming LDL reductions of 1.02 mmol/L across 13 randomized controlled trials. Becker et al. (2009) established its efficacy specifically in statin-intolerant patients. Key concerns include product variability — some brands contain citrinin (a nephrotoxic contaminant) — making third-party tested, standardized products essential.
