Lubriflex3 contains Uniflex, a new, proprietary, patent-pending antioxidant. Uniflex contains the bioflavonoids catechin, baicalein, wogonin and others in a synergistic ratio. Uniflex is a powerful antioxidant that helps protect and preserve cartilage and synovial (joint) fluid from the damaging attack of free radicals. These powerful antioxidants provide deep-down joint comfort. A human clinical study of Uniflex found that 80% said their joints felt better and worked better, 80% said they could function better, and up to 86% said they felt less stiff and more flexible.
