Inositol can improve insulin sensitivity and glycemic control, and may help manage polycystic ovary syndrome (PCOS) and prevent gestational diabetes. The most commonly supplemented forms of inositol are myo-inositol and D-chiro-inositol, but all forms are interchangeably referred to as inositol.

Inositol refers to a group of glucose-like molecules involved in cellular signaling that are synthesized in the body and obtained from dietary sources such as citrus fruits, bran, beans, nuts, and seeds. Inositol is commonly taken as a dietary supplement, primarily in the myo-inositol form, which is the most abundant type in the body.
Inositol supplementation may enhance insulin sensitivity and potentially aid in the prevention and treatment of diabetes, particularly gestational diabetes, and shows promise for managing polycystic ovary syndrome (PCOS). Additionally, it may support weight loss and improve cardiovascular health by reducing blood pressure and cholesterol levels, though further high-quality research is needed to confirm these benefits.
Inositol's main drawbacks include a lack of comprehensive studies on the safety and side effects of orally administered inositol, which means that its side effects are not clearly defined. Although side effects are generally uncommon, high doses (up to 12 grams per day) can lead to gastrointestinal issues such as nausea and diarrhea.
Inositols are naturally occurring molecules in the body that play a role in cellular signaling, particularly in blood glucose control through their influence on insulin signaling and sensitivity. However, further research is necessary to fully elucidate their mechanisms of action.
Studies finding beneficial effects of inositol on gestational diabetes or polycystic ovary syndrome typically administer myo-inositol in the range of 1–4 grams (1000–4000 milligrams) once daily.
