MSM

MSM stands for methylsulfonylmethane, an organic sulphur compound. Sulphur is present as MSM in various foodstuffs (including the sulphur-containing amino acids L-cysteine and L-methionine) and is crucial for our health, but is largely lost during cooking. MSM is composed of 34% sulphur, 34% oxygen, 26% carbon, and 6% hydrogen bonds. It is an important component of connective tissue.
