Red Yeast Rice Extract
Red yeast rice is a popular supplement that is often taken to lower cholesterol -- and for good reason. When red yeast rice is fermented using certain strains of yeast, it may contain high levels of lovastatin, a potent cholesterol-lowering drug. Because lovastatin is a prescription medication, the U.S. Food and Drug Administration (FDA) considers any red yeast rice supplement that contains a significant amount of lovastatin to be "an unapproved drug," not a dietary supplement.
