AOR Inositol Powder - Contains myo-inositol, a B-vitamin-like simple polyol. Inositol forms the basis for phosphatidylinositol (a key cellular phospholipid), is a lipotropic factor, and is involved in cellular signal transduction. Importantly, recent research supports a role for inositol in cellular defense and normal cell growth and differentiation, especially in combination with inositol hexaphosphate (IP6). Recent clinical research indicates that inositol supports mood balance, perhaps because of its involvement in neural signal transduction.
