As you age, the amount of glucosamine created by your body decreases. The result? Your cartilage and bones begin to scrape against each other, your joints become damaged, and the lubricating synovial fluid in your joint spaces becomes thin and watery.

All glucosamine supplements are not the same. To ensure effective absorption and tissue utilization, it's highly recommended that one takes glucosamine in the sulfate form. This is the way glucosamine is found in the body, and it lacks any known toxicity.

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.

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.
