MSM (methylsulphonylmethane) is a form of sulphur. High levels of sulphur are found in muscles, skin and bones, as well as concentrated amounts in the hair and nails. 
 
Sulphur is a component of keratin, the main protein of hair and nails
It is also found in collagen and elastin, which are proteins found in the connective tissue in skin, joints, muscles, bone and blood vessels
The human body contains a relatively large amount of sulphur
Many people do not eat enough raw, sulphur-containing foods on a daily basis
Some people also have genetic errors which inhibit the methylation of sulphur from food sources
This supplement provides 1000mg of MSM per tablet
