Methylsulfonylmethane

Methylsulfonylmethane (MSM) is an organosulfur compound with the formula (CH3)2SO2. It is also known as dimethyl sulfone (DMSO2) or methyl sulfone, and is often sold as a dietary supplement. Its primary uses are as an anti-inflammatory agent and for joint health.

Chemistry

MSM is an organosulfur compound, which means it contains carbon and sulfur. It is a white, crystalline powder that is highly soluble in hot water and in a range of organic solvents. The compound is stable under normal conditions and has a relatively low melting point of 109 degrees Celsius.

Sources

MSM is found in small amounts in many foods and beverages, including milk, coffee, tea, green vegetables, and grains. It can also be produced industrially through the oxidation of dimethyl sulfoxide (DMSO).

Health Benefits

MSM is most commonly used as a dietary supplement for its anti-inflammatory properties and its ability to improve joint health. It has been shown to reduce pain and swelling in osteoarthritis, a common form of arthritis. Some studies also suggest that MSM may improve skin health and complexion, and may help with allergy relief.

Safety and Side Effects

MSM is generally considered safe for most people when taken by mouth or applied to the skin. However, it can cause some side effects, including nausea, diarrhea, bloating, fatigue, headache, insomnia, itching, or worsening of allergy symptoms.
