Methylsulfonylmethane, better known as MSM, is a compound which contains sulfur and is naturally occurring within animals and plants. It is also produced by the human body and is said to act as a crucial natural anti-inflammatory. Research has shown the MSM could be supportive of tendons, joints, ligaments and connective tissue. In order to support our joints and tendons, MSM is said to work with an important building block within our bodies called glycosaminoglycans which are the structural genetic makeup of cartilage.
