Warfarin (Coumadin) is used to slow blood clotting. There are several reports showing that taking chondroitin with glucosamine increases the effect of warfarin (Coumadin) on blood clotting. This can cause bruising and bleeding that can be serious. Don't take chondroitin if you are taking warfarin (Coumadin).
