Superflex is a scientifically balanced ratio of readily absorbed Glucosamine and Chondroitin, the highest quality MSM plus the added benefits of a powerful anti-oxidant formula, exclusively designed to address excess free radical build up around the joint. The key cartilage nutrients, Glucosamine Sulphate, MSM, Chondroitin Sulphate and Hyaluronic acid (HA) are well known for their support for the health of both cartilage, and the thick synovial fluid that oils the joint. Research recommends that feeding a combination of the key nutrients allows them to work together more effectively than any one nutrient alone.
