Could a simple supplement help manage gestational diabetes?
NCT ID NCT07685015
First seen Jul 06, 2026 · Last updated Jul 07, 2026 · Updated 1 time
Summary
This pilot study investigates whether taking myo-inositol (a vitamin-like substance) along with folic acid can improve blood sugar control and reduce oxidative stress in women diagnosed with gestational diabetes. About 40 pregnant women will be randomly assigned to receive either myo-inositol plus folic acid or folic acid alone until delivery. Researchers will track glucose levels, blood markers, and birth outcomes to see if the supplement offers any benefit.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Myo-inositol (a vitamin-like substance) plus folic acid
- What this could lead to
- If effective, myo-inositol could offer a simple dietary supplement to help manage blood sugar in gestational diabetes, potentially reducing the need for insulin.
- What could go wrong
- This is a small pilot study (40 participants) and is not blinded, so results may be biased or not generalizable. The supplement may not improve outcomes beyond standard folic acid alone.
