Glucosamine & Chondroitin are naturally occurring structural components that have recently enjoyed growing popularity. Glucosamine is an amino sugar derived from the chitin of shellfish and is used by the body to support healthy joint structures. Chondroitin, Vitamin C and Manganese complement Glucosamine and work synergistically to provide optimal nutritional support.*

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