Prenatal vitamins consist of a variety of vitamins and minerals that help your baby get the nutrients that are essential for healthy development. During pregnancy, a woman's daily intake requirements for certain nutrients, such as folic acid (folate), calcium, and iron will increase.
You may be tempted to take prenatal vitamins because of unproven claims that they promote thicker hair and stronger nails. However, if you're not pregnant and not planning to become pregnant, high levels of certain nutrients over a long period of time may actually be more harmful than helpful.
