MSM (Methylsulfonylmethane)
Caution: MSM can cause bloating, indigestion, constipation or diarrhea, problems concentrating, fatigue, headache and insomnia. Avoid taking MSM if you're on a blood thinner.

MSM, also known as ‘methyl sulfonyl methane,’ is a compound found naturally in foods such as cow's milk, meat, seafood, fruits and vegetables. MSM is thought to work by contributing sulfur. MSM, with a 34% bioavailability of sulfur according to one source, is reported to be useful in treating musculoskeletal, respiratory, circulatory, eliminative, autoimmune, and degenerative disorders. One of the most widely reported benefits is the relief of pain, inflammation, and muscle spasms, especially when related, but not limited to, osteoarthritis and autoimmune disorders such as lupus, scleroderma, and rheumatoid arthritis. MSM is said to reduce and improve the quality of scar tissue; promote improved healing of joints, tendons, ligaments and collagen support structures; soften, renew and strengthen the skin; and increase blood flow. It is reported to improve mucus membranes, thereby reducing food and airborne allergic reactions, and symptoms related to asthma and emphysema. It is reported to have an anti-parasitic effect, especially against the parasite Giardia. Another reported benefit is its tonic effect on the bowels, which increases peristalsis (waves of motion that move food along the digestive tract). This benefit is helpful to the elderly, those with sluggish colons, and those addicted to laxatives.
