MSM.

MSM - The surprising discovery was that although MSM is such a basic mineral (almost as important as water and food), we are constantly failing to get enough of it. So how basic is this mineral? Natural sulfur is found in the tissues and fluids of all living organisms and is absolutely essential for life! In food it is found in fresh fruit and vegetables, meat, seafood and some grains. Unfortunately, MSM is easily lost during moderate food processing which can rapidly create a deficiency of MSM in our body.

Things like cooking, drying and steaming our food depletes the MSM content of the food. Washing our food or storing it for a long time depletes it as well. Unfortunately, all this makes it hardly possible for us to get enough MSM through our diet. Most people are constantly deficient in MSM.
