Brief Summary

Our study aims to explore the influence of dietary chromium supplementation in the form of chromium picolinate, at different doses (200 µg and 400 µg per day), on the health of pregnant women with gestational diabetes. This study will also provide more information on the safety of this type of supplementation during pregnancies complicated by gestational diabetes mellitus. The main questions it aims to answer are:

  • Does chromium supplementation at various doses in women with gestational diabetes mellitus truly influence their glucido-lipidic metabolism, oxidative/antioxidant balance, and inflammatory state? If so, is it beneficial or detrimental?
  • If this supplementation is beneficial, which dose is the most appropriate?
  • Do these types of supplementation have any side effects on the health of the mother and fetus? The participants will take chromium supplements for 6 weeks (supplemented groups) while the control participants will not take them (healthy and diabetic control groups). Chromium-supplemented participants will undergo a medical check-up every 02 weeks to closely monitor their health status and detect any potential side effects at an early stage. Researchers will compare the biochemical profile, oxidative stress status, and inflammation markers between chromium-supplemented and non-supplemented participants to assess the impact of this trace element. Researchers will compare the effects of chromium supplements at different doses with each other.
