Inositol (or myo-inositol) is a B-vitamin-like molecule that has been shown to have co-factor, and secondary messenger effects. Inositol is a precursor to phosphatidylinositol, which is central to the phosphoinositide cycle. This cycle is essential to multiple  signaling systems, delivering messages from a variety of hormones and neurotransmitters (primary messenger-molecules) from receptors to the inside of the cell.

Research at this dose also supports a role for cellular defense and normal cell growth and differentiation.

At higher doses, such as those found in the Inositol powder, the benefits include supporting mood.
