"Andrew Lessman Glucosamine Sulfate-1500 Andrew Lessman's Glucosamine Sulfate-1500 provides the optimum potency and the ideal form (All Sulfate) of the most important ingredient for the maintenance and repair of healthy joint tissue. Glucosamine is not a medicine that works on joint tissue, but is a vital structural molecule required for our joints to retain their elasticity and healthy structure as we age. Not surprisingly, the benefits of Glucosamine have been shown to extend beyond joint tissue and are also essential for the resiliency and flexibility of other ""elastic"" tissues in the body, such as the skin, arteries, veins and heart valves. Glucosamine Sulfate is always the first line of defense for joint tissues, but unlike ordinary products, we refuse to use unproven Glucosamine HCI (Hydrochloride). We only use the form of Glucosamine established in thousands of studies - Glucosamine Sulfate Glucosamine Sulfate-1500 also provides bonus levels of Potassium, which is essential for heart, nervous system and brain function. No other body part endures more daily use and abuse than our joints, and Glucosamine Sulfate has always been the first choice of experts as a natural tool to help combat and repair the consequences of a lifetime of wear and tear.  As we age, we become more aware of our joints' inability to perform as they did in our youth. Glucosamine Sulfate-1500 provides the most important structural molecule required for our body to combat the normal erosion of these vital tissues over time. Every day, we place enormous demands on our joints and just as Calcium is essential for bones, it only makes sense to provide the same basic structural requirements to our joints with our gentle, yet ultra-high potency Glucosamine Sulfate-1500.
