Chondroitin is a close partner of glucosamine when it comes to improving joint health. It is a naturally occurring nutrient found in the connective tissues of the body that helps maintain the structure and function of joint cartilage. Chondroitin lubricates and cushions the joints by creating a shock-absorbing space within the cartilage tissues. Not only does this action provide cushioning support, but it also helps protect cartilage from being broken down by enzymes. If you suffer from moderate-to-severe joint pain, a combined chondroitin and glucosamine supplement may promote the health of your joints. Consult your doctor to see if a combined chondroitin and glucosamine supplement may be right for you.
