Frequently Asked Questions

What is the source of the glucosamine in GS-500?

The glucosamine sulfate in GS-500 is extracted from chitin, a hard, cellulose-like compound that is the main component in external shells of crustaceans such as shrimp.

Is the glucosamine sulfate in GS-500 stabilized?
Yes. The glucosamine sulfate in GS-500 is stabilized with sodium chloride. Glucosamine must be stabilized and absorbable to see results.  Unstable forms of glucosamine can have less than a 90-day shelf life.
