First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at two dietary supplements, myo-inositol and d-chiro-inositol, to see which one better improves insulin resistance in infertile women with PCOS. 80 women took one of the two supplements for three months. The goal was to see if one is not worse than the other at lowering insulin resistance.
