Red Yeast Rice is a unique natural product that's been used in Asian traditional medical systems since approximately 800 A.D.&ampnbsp; It is produced by the fermentation of red yeast ( &ampnbsp;Monascus purpureus) with white rice.&ampnbsp; NOW&ampreg; Red Yeast Rice is carefully produced to avoid the presence of citrinin, a sometimes toxic by-product of the fermentation process.&ampnbsp; This product is further enhanced with the addition of CoQ10 to support healthy cardiovascular and immune system function, Milk Thistle Extract to support healthy liver function, and Alpha Lipoic Acid to provide antioxidant support.*
