Can vitamin C cause miscarriage?

Vitamin C is an essential nutrient, but a concentrated supplement is not the same as vitamin C from a balanced diet. The effects of a supplement depend on its strength, ingredients, and how much has been taken. Online claims about using vitamin C to end a pregnancy should not guide care.

Miscarriage is an early pregnancy loss. Bleeding, cramps, or pain do not establish the cause by themselves, and a miscarriage can occur without a clear trigger. A clinician may use symptoms, examination, blood tests, and a transvaginal ultrasound to assess the pregnancy.

Do not take further high-dose vitamin C to try to change a pregnancy. Keep the packaging or photograph the label, record the amount and time taken, and contact your maternity team, doctor, or pharmacist for individual advice.

If you have symptoms, arrange assessment rather than waiting for a supplement to provide an answer. Depending on the findings, care may involve monitoring, medication, or a procedure. Information on [Transvaginal Ultrasound](/treatments/diagnostics-and-imaging/transvaginal-ultrasound/), [Medical Management of Miscarriage](/treatments/medical-gynaecology/medical-management-of-miscarriage/), and [Surgical Management of Miscarriage](/treatments/gynaecological-surgery/surgical-management-of-miscarriage/) can help you understand possible discussions.

Seek urgent care for severe or one-sided pain, heavy bleeding, fainting, severe dizziness, fever, or shoulder-tip pain. Call for emergency help if you feel critically unwell. Pregnancy bleeding needs assessment because an ectopic pregnancy and other problems can resemble early miscarriage.

Ask whether the product and amount you took need follow-up, which tests can clarify the pregnancy, and which symptoms mean you should return urgently. If you are considering any supplement during pregnancy, ask about its ingredients and an appropriate dose first.
