Natural Joint Support Methylsulfonylmethane (MSM) and glucosamine are two of the best studied supplements for the treatment of joint problems. MSM is an organic, naturally occurring form of sulfur. Sulfur is concentrated in or around bones, and sulfur supplementation supports healthy muscles, tendons and ligaments. MSM is also helpful for gastrointestinal upset, improved allergy resistance and increasing nutrient absorption in the body. Glucosamine is an amino sugar which is used to create cushioning fluids and tissues around joints. For Aching Joints Both MSM and glucosamine have been tested in many clinical trials. MSM has been found to significantly relieve the pain caused by inflammatory disorders, including nighttime leg cramps, back cramps and muscle spasms. Glucosamine has been found to improve joint health in both young and old individuals, in athletes and in arthritis sufferers. A Dynamic Duo Studies that combined MSM and glucosamine found that their effects on improving joint pain, swelling, mobility and inflammation were more potent in combination than for either compound alone. AOR’s MSM + Glucosamine provides this effective pairing in clinically tested doses and is now shellfishfree and 100% vegetarian.
