Bovine liver is used as a dietary supplement to support pregnancy primarily due to its exceptionally high content of key micronutrients such as iron, vitamin A, vitamin B12, folate, and choline, all of which are critical for maternal health and fetal development. Scientifically, iron deficiency is a common issue in pregnancy and can lead to anemia, which increases the risk of preterm delivery and low birth weight. Bovine liver is among the richest natural sources of heme iron, which is more efficiently absorbed than non-heme iron from plant sources. Additionally, vitamin B12 and folate are essential for neural tube development and the prevention of birth defects. Choline is important for brain development in the fetus.

Clinical guidelines often recommend increasing the intake of these nutrients during pregnancy, and while synthetic prenatal vitamins are common, some practitioners and traditional systems suggest consuming nutrient-dense whole foods like liver. However, liver is also very high in preformed vitamin A (retinol), which, if consumed in excess, can be teratogenic. Therefore, modern recommendations urge caution with liver supplementation, particularly in the first trimester.

There is a moderate level of scientific evidence supporting the use of bovine liver as a nutrient source for pregnancy, primarily for its iron and B vitamin content. However, concerns about vitamin A toxicity mean it should be consumed in moderation and under medical supervision. Use is thus science-based, but with important safety considerations.
