Glucosamine Sulphate is a naturally derived Glucosamine product. Glucosamine has been shown to be an important building block needed by the body to manufacture specialised molecules called glycosaminoglycans, found in cartilage and other structural connective tissue. Unlike some glucosamine preparations, glucosamine sulphate is uncontaminated and derived from natural marine sources, with a minimum purity of over 98.9%. It is rich in sulphur-containing amino acids, critical for connective tissue cross-linking and strength. This glucosamine sulphate product is made using potassium salt, which means it can be given safely to those on a sodium-restricted diet.Directions:1 capsule three times daily with food, or as directed. Caution: Not recommended for individuals with shellfish allergy.
