MSM for diabetes?

A friend of mine who is diabetic told me that she had begun taking MSM and that it has helped her manage her diabetes. I've used it for myself for mild arthritis with good results and in my horses when injured or ill, the vets have been amazed at the quick recoveries. The following is taken from a human diabetes site:

'Methyl-Sulfonyl-Methane (MSM) is a nutritional sulfur compound that is derived from DMSO. Msm can aid in the treatment of diabetes, as sulfur is needed to produce insulin and other vital components necessary for healthy carbohydrate metabolism, such as thiamin and biotin. Msm taken at 10 grams a day ( 2 1/2 teaspoons) can help restore the normal blood sugar levels to the cells. The sulfur makes the cell walls more permeable thus helping restore the pancreas functions to normal, as the blood sugar is absorbed by the cells.'

I was just wondering if anyone had ever tried it on their cats.
