Myo-inositol works by influencing how your body processes insulin. Insulin is a hormone that aids in the regulation of blood sugar levels. When your blood sugar levels rise, your body generates more insulin to lower them. Diabetes occurs when the body either does not create enough insulin or when the cells do not respond adequately to insulin. This can result in dangerously high blood sugar levels. Myo-inositol may aid by boosting your body's insulin utilization.
