Can You Take Prenatal Vitamin and Vitamin A Together?

Dose or timing may matter

The short answer

Prenatal vitamins contain vitamin A (typically 770 mcg RAE). Additional vitamin A supplementation during pregnancy may lead to teratogenic levels. Excess preformed vitamin A (retinol) above 3,000 mcg RAE/day is associated with birth defects.

How to arrange timing

Do not take additional vitamin A supplements during pregnancy unless directed by a healthcare provider. Prenatal vitamin A content is calibrated for pregnancy needs.

Important context

Whether supplements suit you together also depends on dose, product formulation, health conditions, and medication use. Ask a doctor or pharmacist first if you take medication, are pregnant or breastfeeding, or have a chronic condition.
