Red Yeast Rice is the source of certain compounds, one of which is called mevinolin, which not only lowers cholesterol but has some antioxidant properties as well. Melvionlin enzymatically inhibits a comppound called mevalonate, which ends up decreasing LDL cholesterol (the bad kind) while either maintaining or increasing HDL cholesterol(the good kind).
Red Yeast Rice is a unique natural product native to China that’s been used in Asian traditional medical systems since approximately 800 A.D. Produced by fermenting red yeast (Monascus purpureus) with white rice. Red Yeast Rice Extract is carefully produced to avoid the presence of citrinin, a by-product of the fermentation process.
Red Yeast Rice contains HMG-CoA (hydroxymethylglutaryl CoA) reductase inhibitors, which are compounds that inhibit an enzymataic reaction necessary to produce cholesterol in the body, especially in the liver. The liver is considered the main site of cholesterol production and is responsible for over 75% of our total cholesterol supply. The liver contains plenty of HMG-CoA reductase and Red Yeast Rice works to inhibit its action, thereby decreasing cholesterol production. NOW® Red Yeast Rice Extract is carefully produced to avoid the presence of citrinin, a sometimes toxic by-product of the fermentation process.
One clinical study conducted at the College of Pharmacy of Nihon University in Japan found that red yeast rice pigment, referred to as Monasus pigment, was able to inhibit, through oral administration, the growth of malignant tumors induced in laboratory test mice.
i dont see how thats liver toxic...if you got some shitty brand that was contaminated...yes...but that goes for anything in the world that you eat
