What is the maximum daily dosage of vitamin A considered safe for pregnant women?

The maximum daily dosage of vitamin A regarded as safe for pregnant women is 10,000 international units (IU). This amount is based on research indicating that excessive intake of vitamin A, especially in the form of supplements, can lead to teratogenic effects – that is, it can cause developmental abnormalities in the fetus. While vitamin A is essential for reproductive health and fetal development, it is critical for pregnant women to limit their intake to this established safe threshold to mitigate risks associated with hypervitaminosis A.

Vitamin A is found in two primary forms: retinoids (from animal sources) and carotenoids (from plant sources). Most dietary sources provide vitamin A within safe limits; however, supplementation can easily exceed recommended levels, leading to toxicity. The 10,000 IU recommendation aligns with guidance from health organizations, making it crucial for pregnant women to stay informed and cautious regarding their vitamin A consumption, especially during pregnancy.
