If you are to take one thing daily while trying-to-conceive, let it be a prenatal. Folic acid (which prenatals have high amounts of), can decrease the risk of neural tube defects in infants by 70 percent. Prenatals also are plentiful in so many other vitamins, for example: Calcium, Vitamin C, Vitamin A, Vitamin E, et cetera. One thing to point out is DO NOT BUY ANY VITAMINS/SUPPLEMENTS THAT ARE MADE IN CHINA!!!!!! These vitamins/supplements are not regulated by the FDA, and can be impure. Always look at the pill bottle, and make sure they were made somewhere in the United States of America. One last thing....... sometimes prenatals can make you feel sick. Always make sure you take them with food, and a big glass of water. That should help greatly with the nausea. Thanks for reading, and good luck!
