What are some common side effects of prenatal vitamins?

Prenatal vitamins are specifically formulated to support the increased nutritional needs of individuals during pregnancy. The common side effects associated with prenatal vitamins primarily arise from certain components such as iron, calcium, and other minerals included in these supplements.

Nausea, constipation, and abdominal discomfort are widely reported side effects of prenatal vitamins. Iron, which is crucial for preventing anemia during pregnancy, is known to cause gastrointestinal issues, including nausea and constipation in some individuals. The increased intake of essential nutrients can also lead to abdominal discomfort as the body adjusts to the supplementation.

While other options mention side effects like drowsiness or weight gain, these are not typically linked to prenatal vitamins. Instead, they are more often related to hormonal changes during pregnancy or other factors unrelated to vitamin intake. Similarly, diarrhea is not a common reaction to prenatal vitamins; rather, it can be associated with other dietary changes or intolerances. Thus, option B accurately captures the prevalent side effects experienced by those taking prenatal vitamins.
