Short answer

Vitamin C is needed in pregnancy and is usually safe at normal dietary/prenatal amounts, but high-dose supplements are not necessary for most people.

Safe at normal amounts; avoid megadoses

What is the safest way to think about this?

NHS pregnancy vitamin guidance includes vitamin C among nutrients used in pregnancy, but routine megadosing is not the goal.

What is generally okay?

  • Eat vitamin C-rich foods such as citrus, berries, peppers and broccoli.
  • Use prenatal vitamins as directed.
  • Ask before using high-dose immune products.

What should you avoid or double-check?

  • Avoid megadose vitamin C unless your clinician recommends it.
  • Avoid assuming "water soluble" means unlimited.
  • Avoid replacing medical care for infection or fever with supplements.
