CholeRex™ features policosanol, a substance isolated from sugarcane wax that is used to support blood lipid metabolism. It is combined with OptiMag® 125, XYMOGEN’s proprietary blend of two Albion® magnesium chelates. These forms of magnesium are known to be well tolerated and have excellent bioavailability. Combining policosanol and OptiMag 125 is thought to complement each component's cardioprotective benefits.*
