Studies have shown that these drugs contribute to cartilage destruction and inhibit new cartilage formation. Glucosamine sulfate has shown remarkable results in the successful management and even reversal of osteoarthritis. It gets right to the root of the problem - by stimulating connective tissue production and repairing damaged joints. This gives glucosamine sulfate even more appeal. It has proven virtually nontoxic, with few adverse side effects reported.
Glucosamine sulfate is isolated from shellfish chitin and converted to glucosamine sulfate.

It is impossible to be allergic to sulfur because sulfur is an essential mineral. The sulfate form of sulfur is present in relatively high concentrations in human blood. NAG is also produced this way.
