I am trying to get pregnant. what supplement do you recommend me to eat ?

Folic acid: Folic acid has been shown to reduce the risk of neural tube defects and most diets are deficient in it. Beyond that, follow a balanced diet, go easy on the sweets and deserts, avoid alcohol, smoking, and limit your caffeine. Get plenty of rest and get regular exercise. Good luck!

One prenatal vitamin: One prenatal vitamin per day has all the Folic Acid and other vitamins that you need.
