Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Glycosaminoglycans (GAGs), such as chondroitin sulfate and hyaluronic acid, are naturally occurring polysaccharides found in connective tissues, including cartilage. Their use to support joint health is primarily based on their role as structural components of cartilage and synovial fluid. Scientific studies have provided moderate evidence supporting the use of certain GAGs, especially chondroitin sulfate, for joint health. Clinical trials have shown that chondroitin sulfate, often used in combination with glucosamine, may help reduce symptoms of osteoarthritis, such as pain and stiffness, and may slow the progression of cartilage breakdown in some individuals. Hyaluronic acid is also used via intra-articular injections to help lubricate joints, particularly in osteoarthritis of the knee, with some supportive evidence for pain relief and improved function.

However, systematic reviews and meta-analyses have produced mixed results, with some studies showing modest benefits and others finding little to no significant clinical effect. The variability in outcomes may be due to differences in study designs, dosages, and product quality. Overall, while not universally endorsed by all clinical guidelines, the use of glycosaminoglycans to support joint health is supported by a moderate body of scientific evidence, particularly for symptom management in osteoarthritis.
