Inositol is found in all animal tissues, with the highest concentration found in the brain and heart. It is a
component of the outer lining of all cells in the body, contributes to muscular and nerve function, and also
plays a role in helping the processing of fats by the liver.
Endogenous inositol is an essential component of cell membrane phospholipids. Inositol is a constituent of the
intracellular phosphatidyl inositol second messenger system, which is linked to serotonin, norepinephrine, and
cholinergic receptors. Inositol contains a variety of stereoisomers, including myo-inositol and D-chiro-inositol.
Myo-inositol is the most abundant form in the central nervous system. Researchers think that D-chiro-inositol
isomer induces may support insulin sensitivity and healthy testosterone levels in women with ovarian
