WebMD lists additional uses for MSM as treatment for tendonitis, scleroderma, muscle cramps, hair loss, scar tissue, periodontal disease, stretch marks, wrinkles and eye inflammation. It's also claimed that MSM may relieve symptoms related to premenstrual syndrome, poor circulation, Alzheimer's disease, allergies, chronic constipation, high cholesterol, diverticulosis, emphysema, type 2 diabetes, migraine headaches, yeast infections, hangovers, radiation poisoning and pneumonia. None of these claims have been scientifically substantiated, although there's slight evidence suggesting MSM may effectively treat hemorrhoids, osteoarthritis, rosacea and exercise-induced stress.

Possible side effects include insomnia, bloating, nausea, itching, diarrhea and headaches.
