The sales of the supplements chondroitin and glucosamine are an $800 million a year industry in the United States. They are sold to help with joint pain from arthritis. Do they really work?
Chondroitin is a substance that is found naturally in our bodies in the cartilage. The supplement that you can buy at the store is made of shark, cow, or can be a man-made product. Studies to date around its effectiveness have been mixed. Some studies have shown that chondroitin may be effective for the treatment of joint pain and arthritis by showing a decrease in the patient’s pain. However, the majority of studies have not shown any benefit, and chondroitin has not been found to prevent the worsening of arthritis.
