Red yeast rice is cultivated on rice and then ground into a powder. The active ingredient is HMG Co-A reductase inhibitors. HMG Co-A reductase is an enzyme that blocks the synthesis of cholesterol in the liver. Thus 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.
