Hello Thank you for your query. It is not recommended ideally during pregnancy, and especially with a condition like gestational diabetes, to take any kind of supplements without medical advice, so I would advise you not to do so. Moreover, you need to act in strict concert with your obstetrician, physician and a Dietician. I think you urgently need a Dietician. Your condition will normalize once you deliver, but being a Type 1 Diabetic means you have to live with it, and adapt to it. Small frequent meals, and sensible eating to a great extent will allow you to lead a normal life. Please consult a Dietician for a thorough dietary chart, with specific instructions on what foods to take, at what times and in what amount. Please do not lose hope, as you have a lifetime ahead, and you need to keep yourself healthy and focussed. Take care.
