Benefits of NutraBio Glucosamine Chondroitin OptiMSMProvides critical nutrients to help build joint cartilage.*Helps maintain healthy joints and normal connective tissues.*Provides scientifically proven ingredients with anti-inflammatory properties*NutraBio's Glucosamine Chondroitin OptiMSM is an effective joint care formula combining 3 critical nutrients needed to stimulate cells to help build joint cartilage and promote healthy joint tissue. One dose of just 4 capsules provides therapeutic amounts of glucosamine and chondroitin as well as OptiMSM, the highest-quality form of MSM.Active ingredient #1: Glucosamine SulfateGlucosamine (C6H14NO5) is an amino sugar that is utilized by the body to support healthy joint structures. It is unlike other sugars in that it is incorporated into the structure of tissues rather than being used as an energy source. Glucosamine is an important precursor in the biochemical synthesis of glycosylated proteins and lipids and studies indicate that Glucosamine provides the building blocks for constructing cartilage. Since Glucosamine is a precursor for glycosaminoglycans, and glycosaminoglycans are a major component of joint cartilage, supplementing with Glucosamine may help to rebuild cartilage and treat arthritis. Studies indicate that Glucosamine provides the building blocks for constructing cartilage.Active ingredient #2: Chondroitin SulfateChondroitin is naturally found in our cartilage, tendons, and ligaments where it binds to proteins like collagen and elastin. Chondroitin can protect cartilage by helping attract water and nutrients to cartilage and by inhibiting cartilage-damaging enzymes. Insufficient water in cartilage can cause dryness, pain and loss of nutrients in the joints. Chondroitin is partially responsible for the strength, flexibility, and shock absorption in our joints. It provides both structure and lubrication within our joints and has become a popular dietary supplement used in the treatment of osteoarthritis.Active ingredient #3: OptiMSMMSM methylsulfonylmethane) is a naturally occurring source of organic sulfur that is found in the tissues and fluids of all living organisms. MSM is easily absorbed and used by the body and is one of the major building blocks of glycosaminoglycans. Glycosaminoglycans are key structural components in cartilage that play an important role in the maintenance of joint cartilage. MSM supports joint function by donating sulfur for maintenance of healthy connective tissue. MSM is thought to aid in the repair of damaged connective tissue, cartilage, tendons, mucous membranes and skin and to assist with overall joint function.
