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 Dchiro-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 disorders.
