Brief Summary

The investigators aim to compare the effect of different inositol stereoisomers supplementation in lowering insulin resistance levels after 8 weeks of treatment in pregnant women with GDM and in preventing adverse obstetric outcomes. The study population includes 80 women with GDM, randomly allocated to subgroup A (folic acid 400 mcg/day), subgroup B (myo-inositol 2000 mg twice a day), subgroup C (D-chiro-inositol 250 mg twice a day), and subgroup D (Myo-inositol plus D-chiro-inositol 550mg/13,8 mg twice a day). Folic acid or inositol stereoisomers will be administered starting at the enrolling time (24-28 week gestation, after GDM diagnosis) till the delivery. The homeostasis model assessment of insulin resistance (HOMA-IR) and the sensitivity index (QUICKI) will be checked at the moment of the diagnostic oral glucose tolerance test (24-28 weeks) and after 8 weeks of treatment. Obstetric outcomes, the rate of women needed insulin therapy and insulin dosage will be registered.
