Glucosamine Chondroitin Extra Strength is 50% more potent than typical combination products. This means you can obtain a clinically substantiated dosage of these popular joint support nutrients in just two tablets instead of three. Glucosamine Chondroitin Extra Strength provides important building blocks for healthy joints and connective tissues. Glucosamine, an amino sugar, is an essential structural component of glycosaminoglycans, large molecules that help lubricate joints, nourish cartilage and connective tissue, and assist in wound healing. Manganese is involved in the synthesis of collagen, and chondroitin sulfate lends additional structural support via its high degree of interaction with collagen fibers. Molybdenum aids in the complete metabolism of glucosamine and chondroitin.
