INS and gestational diabetes: Previous studies have observed that supplementation of myo-inositol (61–63), probiotics (64–67), or zinc (68, 69) for 6–8 weeks in women already diagnosed with GDM at 24–28 weeks of gestation, improved glycemic control in these women, as reflected in lower maternal circulating insulin, glucose, triglycerides, total and LDL-cholesterol, and increased insulin sensitivity.
