Organic sulphur can be consumed by eating a protein-rich diet, but with a normal diet we get significantly less MSM than by using dietary supplements, for example in the form of MSM powder. One of the sulphur sources is cow’s milk – a litre of cow’s milk contains 3 mg of MSM, which is especially true for unheated or unpasteurised milk.
Another source of organic sulphur are fresh tomatoes, which, however, contain less than 1 mg of MSM per kilo. The third source of natural or organic sulphur is corn. Natural sulphur is also found in a variety of grains, fruits and vegetables.
