The NOW Foods Vegetarian Red Yeast Rice Supplement is a natural product that has been used by Asian traditional herbalists since approximately 800 A.D. It offers nutritional support. It is produced by fermenting red yeast (monascus purpureus) with white rice and red yeast rice is commonly used in cooking applications to enhance the color and flavor of foods. Peking Duck is an example of the coloration and aroma imparted by this grain. NOW dietary supplements are carefully produced to avoid the presence of citrinin an unwanted by-product of the fermentation process. The 600mg pills are packaged in a 60-count container. Take two red yeast capsules one to two times daily preferably with food. It is a vegetarian/vegan product that is non-GMO and processed in a GMP quality assured facility.
