Inositol is a dietary supplement that exists in the two forms of myo-inositol (MI) and d-chiro-inositol (DCI) (so called stereoisomers of inositol). Inositol has proven therapeutic activity in PCOS: Both forms have insulin-sensitizing activity, and Myo-inositol (MI) also has an effect on FSH signaling.
