Glucosamine is a natural compound found in the body, particularly in cartilage, which is the tissue that cushions joints. It is often taken as a dietary supplement to help support joint health and reduce pain associated with conditions like arthritis. Many people believe that glucosamine can help maintain the integrity of cartilage and may even promote its repair. In addition to its potential benefits for joint health, glucosamine is sometimes combined with other supplements, such as chondroitin, to enhance its effects. While research on its effectiveness is mixed, many individuals report positive results, making it a popular choice for those seeking relief from joint discomfort.
