Formulation Notes

Glucosamine is an essential building block for the formation of glycosaminoglycans (GAGs) and proteoglycans, the main components of cartilage tissue. These compounds promote water retention within the joint, giving it resiliency by acting as a lubricant and a means to absorb shock.

Natural color variation may occur in this product.

NOW Foods developed the glucosamine test method chosen as the official AOACI industry standard method.
