ABSTRACT
Glucosamine and chondroitin sulfate (CS) are by far the most popular products sold for providing relief from joint pain. In addition, many products include them as major ingredients in their cocktail. They are often referred to as nutraceuticals because they have both nutritional and pharmaceutical characteristics. For the most part, they are considered safe to use long term at the typical doses of 1500 mg/day for glucosamine and 1200 mg/day for CS (Jordan et al., 2003; Hathcock and Shao, 2007).
