Inositol is a sugar naturally made in the body. It is also found in certain foods, including beans, citrus fruits, whole grains, nuts and seeds, and organ meats. Though it is always good to get your nutrition from whole foods, if your body is not able to get sufficient Inositol from your diet alone, you may need Inositol supplements to fulfill your requirements. Inositol is typically found in nine forms. The most common among them are myo-inositol and D-chiro-Inositol. Both of them are involved in cellular signaling and insulin sensitivity.
