What is Inositol?
Inositol is a carbohydrate, produced by the body and found in some foods. Some consider inositol as a vitamin that belongs to the family of B-vitamins.
Made in the liver and kidney, up to 4g of inositol is available each day for various roles in the body. Ninety-nine percent of inositol in the body is in the form of myo-inositol (MI)i.
Intake of myo-inositol through diet is estimated to be up to 1g per dayii. Dietary sources rich in myo-inositol include fruit, beans, grains and nuts. Fresh vegetables and fruits contain more myo-inositol than frozen or canned productsiii

A growing body of research has investigated the association between inositol and diabetes.
Benefits of Inositol
Scientific studies to date have shown that inositol can mimic the actions of insulin activity and may increase insulin sensitivity. Inositol has been shown to lower fasting blood glucose and HbA1c. Inositol has been used as a supplement in treating Polycystic ovary syndrome (PCOS), metabolic syndrome, and gestational diabetes (GDM).[iv]
Inositol supplements are well tolerated.
