Chondroitin sulfate attracts and holds large amounts of water to the cartilage-building proteoglycan molecules. Since cartilage has no blood supply, this fluid is necessary to nourish and lubricate joints.

The body uses glucosamine sulfate, a natural compound, to stimulate cells to create one of the main building blocks of joint cartilage – proteoglycans. To ensure effective absorption and tissue utilization, this formula uses glucosamine in the sulfate form to provide the sulfur necessary for supporting the repair of cartilage.

MSM (methylsulfonylmethane) is a sulfur-containing molecule found in various plants and some body tissues. It is a natural and efficient source of the sulfur that is used by many of the body's structural molecules, including joint cartilage.

This supplement contains 250 mg of vitamin C (ascorbic acid), a water-soluble substance found in citrus fruits and green vegetables. Vitamin C may effectively support healthy immune function. It is also an important antioxidant for promoting overall health.

All NSI supplements are packaged in HDPE (High Density Polyethylene) bottles. These bottles keep moisture vapor out, protecting the freshness and integrity of their contents, and are 400% more effective compared other brands currently using PET (Polyethylene Terephthalate) bottles. HDPE bottles do not break as glass can and are also recyclable so we urge you to please recycle them.
