Glucosamine: This is a natural compound found in cartilage, the tough tissue that cushions joints. It is a building block for the formation of glycosaminoglycans (GAGs) and proteoglycans, which are main components of cartilage tissue and help attract water to form a joint cushion.
Chondroitin Sulfate: Another natural component of connective tissues like cartilage, chondroitin helps maintain the structure and elasticity of cartilage by absorbing fluids and blocking enzymes that can degrade cartilage.
