myo-Inositol

myo-Inositol is a unrated form of Inositol (myo-Inositol), used in 161 on-market products .

Basis: Same molecule as unspecified 'Inositol' (C6H12O6, MW 180.16); declared weight is inositol weight, no conversion

Why this tier: Most labels say only 'Inositol'; the clinical literature (PCOS, gestational diabetes, psychiatric trials) uses myo-inositol, which is therefore the default interpretation. No comparison of forms applies. No head-to-head human bioavailability or efficacy comparison of this form was located in PubMed searches.
