Doctor's Best Glucosamine Chondroitin MSM provides three important nutrients which help maintain healthy joints and connective tissues: glucosamine, chondroitin and Methylsulfonylmethane (MSM, from OptiMSM). Glucosamine sulfate helps joint health for joint lubrication and better joint movement and flexibility.
Cartilage, composed of proteoglycans, is mainly located on bones and near joints and consists primarily of collagen protein with side chains called chondroitin sulfate. MSM supplies bioavailable sulfur needed for joint health. OptiMSM is purified via distillation for highest purity and consistency and is an excellent source of bioavailable sulfur.
