MSM is sold as a dietary supplement and marketed with a variety of claims, often in combination with glucosamine and/or chondroitin for helping to treat or prevent osteoarthritis. According to one review, “The benefits claimed for MSM far exceed the number of scientific studies” Small-scale studies of possible treatments with MSM have been conducted on both animals and humans. These studies of MSM have suggested some benefits, particularly for treatment of oxidative stress and osteoarthritis.Methylsulfonylmethane in osteoarthritis knee pain relief reported significant improvement in pain outcomes in the treatment group compared to comparator treatments MSM may reduce oxidative stress and inflammation. In one small human trial, MSM has been shown to protect muscles from damage by reducing the amount of oxidative stress damage incurred through exercise.

People take MSM by mouth and apply it to the skin for chronic pain, osteoarthritis, joint inflammation, rheumatoid arthritis, osteoporosis, inflammation around the joints (bursitis), tendinitis, swelling around the tendons (tenosynovitis), musculoskeletal pain, muscle cramps, hardened skin condition called scleroderma, scar tissue, stretch marks, hair loss, wrinkles, protection against sun/wind burn, eye inflammation, oral hygiene, gum disease, wounds, cuts, and abrasions/accelerated wound healing.

People also take MSM by mouth for relief of allergies, chronic constipation, “sour stomach”, ulcers, a bowel disease called diverticulosis, premenstrual syndrome (PMS), mood elevation, obesity, poor circulation, high blood pressure, and high cholesterol. It is also taken by mouth for type 2 diabetes, liver problems, Alzheimer’s disease, to control snoring, lung disorders including emphysema and pneumonia, chronic fatigue syndrome, autoimmune disorders (systemic lupus erythematous), HIV infection and AIDS, and cancer (breast cancer and colon cancer).

“MSM is also taken by mouth for eye inflammation, mucous membrane inflammation, temporomandibular joint (TMJ) problems, leg cramps, migraine, headaches, hangover, parasitic infections of the intestinal and urogenital tracts including Trichomonas vaginalis and Giardia, yeast infection, insect bites, radiation poisoning, and to boost the immune system.”—courtesy
