D-chiro-Inositol is an epimer of myo-inositol found in certain mammalian glycosylphosphatidylinositol protein anchors and inositol phosphoglycans possessing insulin-like bioactivity. D-chiro-Inositol is used clinically for the treatment of polycystic ovary syndrome (PCOS) and diabetes mellitus, which can reduce hyperglycemia and ameliorate insulin resistance[1][2][3].
