Story of Red Yeast Rice
Red yeast rice is a substance that's extracted from rice that's been fermented with a type of yeast called Monascus purpureus.
Red yeast rice naturally contains several ingredients. These include a number of monacolins, most importantly monacolin K. It also contains isoflavones, and monounsaturated fatty acids. Taste-wise, red yeast rice is not much different than regular white rice.
