What are prenatal supplements?

Prenatal supplements, or prenatal vitamins, are taken by individuals before conception and during pregnancy to provide essential nutrients for both parent and child. They typically contain a combination of vitamins and minerals, and iron and folic acid are particularly recommended for proper fetal development and to prevent complications.

What are the main benefits of prenatal supplements?

Prenatal supplements, particularly those containing multiple micronutrients (MMN), can reduce the risk of low birth weight and small-for-gestational age infants and also lower the risk of stillbirth and the risk of diarrhea in children. However, the benefits of MMN (compared to iron and folic acid alone) may vary based on dietary intake and require further investigation in different income settings.

What are the main drawbacks of prenatal supplements?

Prenatal supplements are generally safe when taken as recommended, but exceeding the daily intake of certain vitamins and minerals (particularly vitamin A) can be harmful to the fetus and may cause birth defects. Additionally, some users may experience constipation, primarily due to iron content in the supplements.

How do prenatal supplements work?

Prenatal supplements consist of various vitamins, minerals, and nutrients that support maternal health and fetal growth through multiple mechanisms of action. The specific functions of each micronutrient can be explored in detail on their individual pages.
