Inositol is a naturally occurring nutrient found in various forms, the most common being myo-inositol. Even though it is sometimes referred to as a vitamin, it is not. This nutrient is not essential in humans as we can make it in the body from glucose. Inositol is a direct precursor of phospholipids which are a major component of cellular membranes. It helps to maintain proper electrical energy and nutrient transfer across the cell membrane. It also acts as a lipotropic which converts fats into other useful products. It helps establish healthy cell membranes, which facilitate nerve impulses. It is sometimes used therapeutically in the treatment of OCD/Panic disorder.
