Methylsulfonylmethane (MSM) is an organic sulfur-containing compound found naturally in plants, animals, and humans, though in small amounts.

MSM reduces joint pain and inflammation by turning down the genes that trigger inflammatory signals. it also directly inhibits cartilage from breaking down. consistent results in arthritis studies at 1-3g per day.

in a 16-week human trial at 1-3g daily, it produced significant improvements in facial wrinkles, firmness, skin hydration, elasticity, tone, and texture.

air is made primarily of keratin, and keratin needs sulfur to form properly. MSM supplies that sulfur. it also reduces scalp inflammation, which is a major cause of hair loss.

MSM reduces hay fever and seasonal allergy symptoms (both nasal congestion and lower respiratory symptoms) while also increasing energy levels.

MSM was administered orally to mice with genetic predisposition to lymphoma and rheumatoid arthritis. there was a significant delay in development of lymphomas as well as decreased tumor incidence compared with control. in a separate pilot study, female rats given DMBA carcinogen while receiving MSM in their drinking water did not develop tumors, while mammary tumors were seen in control animals. so MSM both prevented lymphoma development and completely blocked mammary tumor formation from a known carcinogen.

MSM protects the liver from toxic damage including from Tylenol overdose, through the same glutathione pathway as NAC.

MSM reduces post-exercise muscle soreness and damage by increasing the body's antioxidant capacity. athletes use it to recover faster.

may help to heal the damaged lining of the digestive tract, thus preventing or helping recover from leaky gut syndrome, colitis, and inflammatory bowel diseases.

A test-tube study showed that MSM effectively restored glutathione levels and reduced inflammatory markers in mouse cells that had been weakened with HIV proteins.

msm will also enhance the absorption of pills you take.
