The claimEvidence B · meta-analysis
Red yeast rice = natural, safer statin
The evidence
Monacolin K is chemically identical to lovastatin — 'natural' brings dose variance + citrinin contamination.
Why the claim spreads
The word 'natural' rebrands a drug as a supplement — it sidesteps the stigma around statins and skips the prescription entirely.
The mechanism, in brief
Red Yeast Rice (RYR) is not 'rice' — it's the product of rice fermented with a red filamentous fungus:
