Liver contains extremely high vitamin A (retinol) — 3oz chicken liver has 12,000+ IU vs. the 10,000 IU upper limit during pregnancy. ACOG advises limiting liver intake.
💡
Key Takeaway: Liver should be limited during pregnancy due to extremely high vitamin A (retinol) content. Excess preformed vitamin A is teratogenic — associated with birth defects. Occasional small portions are unlikely to cause harm, but daily consumption or large servings should be avoided. Other organ meats carry similar concerns.
