MSM
MSM (Methylsulfonylmethane) is commonly used to support pain relief and in particular discomfort caused by osteoarthritis.
Taking MSM by mouth seems to slightly reduce some symptoms of arthritis of the knee, such as pain and joint movement, making the joint less painful and allowing day to day activity to continue.
MSM is well suited to be combined with chondroitin and glucosamine, as an ideal joint support complex.
