Chondroitin sulfate is a glycosaminoglycan (GAG) naturally present in many body tissues and is an especially important component of joint cartilage and synovial tissue.* Chondroitin promotes water retention within the joint, giving it resiliency by acting as a lubricant and a means to absorb shock.* This nutrient thus helps to support the maintenance of healthy, flexible joint tissue and promotes proper joint mobility and comfort.* Natural color variation may occur in this product.
