Preconception and prenatal vitamins 

Personal health and wellness have been proven to positively influence conception and healthy pregnancy. FCI encourages patients to take a preconception nutritional supplement one to three months prior to trying to conceive and continuing through the first 10 weeks of pregnancy. Near the end of the first trimester, supplement needs can evolve and a more traditional prenatal vitamin may be appropriate.  

Fertility Centers of Illinois is proud to recommend Luminary Vitamins and Theralogix as the products are independently and third party verified and offer high-quality, evidence-based nutritional supplements to support patients along their fertility journeys.
