Supports joint function *Glucosamine sulfate nutritionally supports healthy joints and the body's ability to generate and regenerate connective tissue. Glucosamine is a naturally occurring compound present in joint cartilage that is necessary for the synthesis of proteoglycans, the protein molecules responsible for giving cartilage its strength and resilience. Sulfate, another component of proteoglycans, works synergistically with glucosamine in cartilage metabolism. Glucosamine Sulfate enhances and utilizes the intrinsic compounds in cartilage in order to nutritionally provide for healthy cartilage and joints. Ingredients:Glucosamine Sulfate 1,000 mg.
