Sugar pill or savior? supplement may cut insulin use in pregnancy diabetes
NCT ID NCT03875755
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether myo-inositol, an oral dietary supplement, can help pregnant women with gestational diabetes control their blood sugar without needing insulin shots. About 1,080 women with newly diagnosed gestational diabetes will receive either myo-inositol or a placebo alongside standard diet and lifestyle advice. The goal is to see if the supplement reduces the number of women who require insulin therapy.
