Glucosamine

Glucosamine is a naturally occurring chemical compound in the human body. It is an amino sugar and one of the building blocks of cartilage. Cartilage covers and protects the ends of the bones, allowing bones to move smoothly against each other. Glucosamine comes in two forms – glucosamine sulfate and glucosamine hydrochloride. Dietary supplements containing glucosamine are useful for people with osteoarthritis, since it helps to relieve the pain and prevents the breakdown of cartilage in osteoarthritis.
