Does MSM have any proven effects on insulin, blood sugar, blood pressure, or peptic ulcer?
No. Sulfur is a component of many amino acids and hormones, and is required for the production of many more. But just because sulfur is required to produce insulin, it is not correct to believe that taking sulfur as a supplement (e.g., in MSM) would have any effect on the body’s production or secretion of insulin. The regulatory pathways for blood sugar metabolism are far more complex than that.
