Red yeast rice is traditional Chinese medicine made from a yeast that naturally grows on starch. For supplemental purposes it is cultivated on rice and then ground into a powder. The active ingredients in red yeast rice are HMG Co-A reductase inhibitors, the same substances that are used in the cholesterol lowering medications that bear the same name.
HMG Co-A reductase is an enzyme that blocks the synthesis of cholesterol in the liver. Thus red yeast rice inhibits the formation of harmful LDL cholesterol, reduces total cholesterol and increases HDL cholesterol. High cholesterol, heart disease and heart attack risk are lowered when one uses red yeast rice. Other components in red yeast rice, essential fatty acids, amino acids, isoflavones and trace minerals support red yeast rice’s cardiovascular effects.
Red yeast rice supplements are found encapsulated. Red yeast rice products should be standardized as an assurance of the amount of active components they contain. Red yeast rice can be found in combination products for cholesterol control.
