    Inositol refers to a group of molecules (isomers) that are structurally similar to glucose and involved in cellular signaling.[1][2] Inositol is synthesized in the human body, but is also obtained in the diet from foods like citrus fruits, bran, beans, nuts, and seeds.[3][4][5] Inositol is also taken as a dietary supplement. The majority of inositol supplements contain the myo-inositol form, as it is the most plentiful type of inositol found in the body.[6]
