The body uses glucosamine sulfate, a natural compound, to stimulate cells to create one of the main building blocks of joint cartilage -- proteoglycans.

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.

MSM (methylsulfonylmethane, or dimethyl sulfone) 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.

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.

Pregnant or lactating women, diabetics, hypoglycemics, and people with known medical conditions and/or taking drugs should consult with a licensed physician and/or pharmacist prior to taking dietary supplements.
