Side Effects of Red Yeast Rice Capsules

Red yeast rice is a dietary staple in many Asian countries and is made by growing yeast on rice. It is available in supplement form and contains a compound called monacolins, which may be beneficial in reducing LDL, or "bad" cholesterol. The same monacolin compound is found in some cholesterol-lowering prescription drugs. While consumption of red yeast rice may offer some health benefits, there may be some side effects as well. Note that red yeast rice supplements have not been approved by the U.S. Federal Drug Administration (FDA) for consumption. Always consult a doctor with any questions.

Liver Problems

Increased Risk of Bleeding

Mild Discomfort
