Glucosamine and chondroitin are two of the most basic and important molecules necessary for the support of joints and the synthesis of cartilage within those joints which supports mobility and reduces discomfort.‡

Manganese is added to the formula for its properties relative to supporting healthy inflammation levels in the joints and connective tissues, reducing discomfort.‡
