Ovasitol is formulated with a unique combination of myo-inositol and d-chiro inositol. Recent research concludes the combination of the two inositols is more effective than either form of inositol alone. Ovasitol contains the body’s normal 40 to 1 ratio with 2,000 mg of myo-inositol and 50 mg of D-chiro-inositol.
