Doctor's Best Glucosamine Chondroitin MSM 120 Capsules

Doctor's Best Glucosamine Chondroitin MSM 120 Capsules
Healthy joints may get worn away by sports injuries, overuse, or wear-and-tear that can cause joint pain. 
Glucosamine helps stimulate the manufacture of proteoglycans in healthy joints. 
Chondroitin is a component of healthy joints that attracts water to the tissue, which helps the joint stay elastic and function as a shock absorber for joints. 
MSM is a natural sulfur to help form antioxidants and serve as a key structural nutrient in healthy joints and may help to give shape, strength and support to other tissues within the body. 
This combination of ingredients has been proven to support joint structure, function and comfort.
Benefits:
Supports joint structure, function and comfort
Potent combination of three proven, purified ingredients that help the body manufacture proteoglycans in healthy joints. 
Proteoglycans contribute to the maintenance of sound joint structure, ultimately enhancing healthy joint function.
Each serving provides 1500mg of glucosamine sulfate, 1200mg of chondroitin sulfate, and 1000mg of MSM
Non-GMO, Gluten Free, Soy Free
How does it work?
Articular cartilage is a connective tissue composed of specialized cells (chondrocytes) embedded in a matrix of protein fibers (mostly collagen) and clusters of complex proteoglycan molecules that consist of a protein core with numerous side chains. These side chains, chiefly chondroitin sulfate and keratin sulfate, are long polysaccharide molecules called glycosaminoglycans.
Chondroitin sulfate and the other glycosaminoglycans strongly attract water due to the negative charges of their sulfate groups. These negative charges also repel each other, creating spaces between glycosaminoglycan side chains where water can enter. This combination of solid and liquid gives joints a compressible quality which may ultimately enhance healthy joint function.
Glucosamine is a fundamental building block for proteoglycans and glycosaminoglycans. Glucosamine sulfate (GS) helps to maintain joint health through its ability to both act as a component of and stimulate formation of glycosaminoglycans and the hyaluronic acid backbone essential for the formation of proteoglycans. MSM’s use in joint stems from its organic sulfur support of the disulfide bonds that reinforce collagen fibers, a property that’s believed to promote joint integrity and resilience. .
