Inositol
(myo-inositol; phosphatidylinositol)
DESCRIPTION/FUNCTION
- Inositol is often classified as a B-vitamin. As phosphatidylinositol, it is
present in cell membranes. Functions include the mediation of cellular responses
to external stimuli, nerve transmissions, and regulation of enzyme activity. It
also exerts lipotropic activity (fat metabolism in the liver).
DRI (RDA or AI for Adults)
- None. Classified as vitamin-like, but the body can manufacture it.
MAJOR SOURCES
- Organ meats (liver, heart), whole grains, vegetables, nuts, legumes.
MAINTENANCE/THERAPEUTIC RANGE
POSSIBLE THERAPEUTIC APPLICATIONS

COMMENTS
- Inositol exerts its psychological actions by increasing GABA levels (gamma
aminobutyric acid). GABA is an inhibitory neurotransmitter. Inositol may also
have antioxidant properties.
