Inositol, or more precisely myo-inositol, is a carbocyclic sugar that is abundant in brain and other mammalian tissues, mediates cell signal transduction in response to a variety of hormones, neurotransmitters and growth factors and participates in osmoregulation. It is a sugar alcohol with half the sweetness of sucrose (table sugar). It is made naturally in humans from glucose. A human kidney will produce around two grams each day. Other tissues synthesize it too, and the highest concentration is in the brain where it plays an important role making other neurotransmitters and some steroid hormones bind to their receptors. In the last 10 years, myo-inositol gained importance in the management of PCOS due to its efficacy, safety profile and worldwide availability.
