Glucosamine & Chondroitin provides significant benefit for joint and cartilage support as indicated in clinical research.* Supplementing with glucosamine and chondroitin sulfates can provide significant benefit for musculoskeletal support.* Chondroitin sulfates, a category of glycosaminoglycans (GAGs), are required for the formation of various important components of joint cartilage.* These two nutrients – glucosamine and chondroitin – support joint function and mobility by enhancing the body's production of GAGs and preventing their degradation.* Clinical research indicates that supplementing with chondroitin sulfates supports joint structures.* Some studies have concluded that the combination of glucosamine sulfate and chondroitin sulfate protects and supports joint surfaces more effectively than glucosamine sulfate alone.* Thorne's Glucosamine & Chondroitin is NSF Certified for Sport®. • Joint Support*
