How is glucosamine in this cream different from a glucosamine supplement I take orally?

Glucosamine in a body cream serves a different purpose than in a dietary supplement. Oral glucosamine supplements are intended to provide building blocks for cartilage and synovial fluid from within the body. In this cosmetic cream, glucosamine is a topical ingredient. Its inclusion makes the product's intended use easy to understand—it is aimed at areas linked with movement and physical strain. When massaged into the skin, the cream adds slip for self-massage, helps relax stiff-feeling areas, and leaves the skin less dry. The primary benefits come from the act of massage, which encourages local circulation and a sense of ease, combined with the emollient properties of the cream for skin maintenance. It is not absorbed to act like an internal joint supplement and is for external use only.
