MYPP-trial: Myo-inositol Supplementation to Prevent Pregnancy Complications in Women With Polycystic Ovary Syndrome.

Participants randomly allocated to the intervention group will receive 4 grams myo-inositol added to their routinely recommended 0.4 mg folic acid supplement, divided over two daily sachets of sugary powder throughout pregnancy.

The control group will receive similar looking sachets of supplements containing only the standard dose of 0.4 mg folic acid without the added myo-inositol supplement as part of the current standard-of-care recommendation.
