HealthPregnancy and lactation
Last reviewed: January 9, 2026
Summary
A well-planned vegan diet can support pregnancy and lactation, but it requires attentive planning (B12, iodine, iron, vitamin D, omega-3, and adequate energy/protein). Clinical monitoring is appropriate, as it is for any pregnancy.
Evidence Summary
- Guidelines recognize adequacy with planning; emphasize B12 and iodine.
- Outcomes depend heavily on diet quality and healthcare access. Evidence quality: Moderate (guidelines + mixed observational evidence) Limitations / nuance: “Vegan” pregnancies in research vary from whole-food diets to ultra-processed diets; results may not generalize. Bottom line: Not automatic, but feasible with planning and routine prenatal care.
Supporting Evidence
Caveats: Clinical monitoring is appropriate, as with any pregnancy.
