1800 mg Glucosamine HCl and 600 mg Chondroitin Sulfate in a molasses flavored pellet. Glucosamine and chondroitin are found naturally in the bodies of animals, and are necessary for normal joint function. Glucosamine is a natural precursor of glycosaminoglycans (GAGs) and hyaluronic acid. Chondroitin is the primary GAG found in cartilage. Manganese is an important cofactor for the formation of GAGs, and ascorbic acid is required for collagen formation. Together, they act synergistically to support normal joint function.
