Red Yeast Rice + CoQ10 combines two complementary ingredients for heart and blood vessel health.* Included in this formula are a 10:1 red yeast rice extract that is carefully fermented to avoid the presence of the natural byproduct citrinin, and coenzyme Q10, which is both a critical componet in the production of bodily energy and a lipid-soluble antioxidant in its reduced ubiquinol (QH) form.*
