When a woman begins thinking about starting a family, maintaining a healthy diet and lifestyle becomes a top priority. While many women begin taking supplements after they conceive, some research shows that prenatal vitamins may be helpful for pregnancy and may possibly boost fertility. Of course, there are many factors that influence a woman’s fertility, and while taking prenatal vitamins will not guarantee to increase your odds of conceiving, the high level of nutrients in these types of supplements can still potentially improve your odds of achieving and maintaining healthy pregnancy.
