Nature's aid Glucosamine MSM &Chondroitin

Glucosamine is an amino sugar, which means it is derived from an amino acid and a sugar molecule.  It occurs naturally in the body, but production may decrease with age.  MSM is a naturally occurring source of sulphur, which is necessary for the structure and function of many compounds in the body. Chondroitin sulphate is a chain of alternating sugars that is typically attached to proteins as part of a structural substance known as a proteoglycan.
