Clinical studies show glucosamine sulfate is a key building block for connective tissue and cartilage. The glucosamine sulfate in doctor-recommended GS-500 dietary supplement is up to 90% absorbable, which makes it more readily available to the body to support healthy articular cartilage.

GS-500 is the original glucosamine sulfate product in the United States—the standard by which all the rest are judged.

ETI is an FDA-registered Drug Establishment.

Husband and his Doctors have noticed great relief in his hand arthritis, even the size of the "knots" and mobility of his hands.

I do like this brand but I still do not know about this product with out Chondroition in it. I think I may have more pain now. Will try the one with the Chondroition in it and compare the different.
