The new PROCARTIL 900 IMPROVED FORMULA contains 400 mg chondroitine with low molecular weight for better uptake by the body, and 500 mg glucosamine sulphate of marine origin : These two molecules are synthesised by the organism. 2.66 mg copper gluconate and 17 mg manganese gluconate complete the active complex. They work synergistically with glucosamine and chondroitine sulphate. Studies have proven the effectiveness of the combination of the two active ingredients in the repair of cartilage. The effect of the active complex is further strengthened by the addition of the antioxidants copper and manganese. By “lubricating” the joints, PROCARTIL 900 gradually reduces discomfort.
