Prenatal vitamins cannot entirely prevent alcohol-related birth defects, but they can help reduce the risks associated with fetal alcohol spectrum disorders (FASDs) [1]. FASDs refer to a range of effects that can occur in a person whose mother drank alcohol during pregnancy [1].

Prenatal vitamins, particularly those containing folic acid, can support healthy fetal development and reduce the risk of certain birth defects, such as neural tube defects [1][2]. However, no specific evidence indicates that prenatal vitamins can directly reduce alcohol-related birth defects [1].

It is essential to understand that the most effective way to prevent alcohol-related birth defects is to abstain from alcohol consumption during pregnancy [1]. Alcohol can cause permanent damage to the developing brain and other organs [1].

In summary, while prenatal vitamins play a crucial role in supporting a healthy pregnancy, they cannot replace the need to avoid alcohol consumption during pregnancy to reduce the risk of FASDs.
