Methylsulfonflmethane (MSM) is a naturally occurring substance with pain-relieving properties. MSM blocks the transmission of nerve impulses that travel along C fibers, specialized nerve cells that send messages of deep, aching pain to your brain. Unlike acute pain, which serves as a warning that something is wrong, this chronic type of pain is seemingly without purpose and is therefore especially cruel. It's also much more resistant to treatment, which is why MSM is such a blessing for the many patients who have benefited from it.
MSM also reduces inflammation. When tissues become inflamed, they swell with fluid, which puts pressure on nerves and causes pain. Inflammation is a characteristic feature of arthritis, and the most popular drugs for arthritis pain- nonsteroidal anti-inflammatory drugs ( Motrin, asprin etc.) achieve their analgesic effects by blocking the inflammatory process. Unfortunately, that's not all they do. They also damage the lining of the stomach and accelerate cartilage destruction. MSM eases inflammation without these unwelcome side effects. It is extremely safe ... studies have found it to be less toxic than table salt. Its only side effect, seen at high doses, is minor gastrointestinal discomfort.
The "S" is MSM stands for sulfur, the likely source of its healing and pain-relieving properties. This mineral, which is present in virtually all cells, is concentrated in the muscles and connective tissues. Sulfur containing compounds are abundant in cartilage and in the synovial fluid that lubricates your joints. In a 1995 study, researchers found that the sulfur concentration in arthritic cartilage was approx. one-third the level of normal cartilage. Other studies have shown that arthritic patients have lower levels of sulfur-containing amino acids, the building blocks of protein. Understanding the importance of sulfur to protein-rich tissues as muscle and cartilage, it is clear that sulfur has a history of use in the treatment of various joint pain.
Finally, MSM dilates blood vessels and enhances blood flow. Though this doesn't directly affect pain, it does hasten the delivery of vitamins, minerals, and other nutrients to speed healing. MSM is not a quick fix but instead a long-term solution that addresses the underlying causes of arthritis pain - inflammation, poor blood flow and deficiencies of tissue-building nutrients. Even though MSM can be effective alone, it is more effective when combined with other joint-healing supplements.
