Vitamin C and miscarriage: what should you know?

Miscarriage is an early pregnancy loss, and its cause often cannot be identified from symptoms alone. Taking vitamin C in food is different from taking a concentrated supplement. A supplement cannot confirm whether a pregnancy is continuing, and it should not be used to try to bring on or stop bleeding.

Bleeding and cramping can occur for reasons other than miscarriage, while some miscarriages begin with few symptoms. Assessment may include a pregnancy history, examination, blood tests, and a transvaginal ultrasound. The scan can help establish what is happening and whether follow-up is needed.

If you are pregnant and have taken vitamin C, tell your midwife, obstetrician, or doctor the product name, amount, and timing. Do not take additional high-dose supplements or combine products without checking the label and getting personalised advice.

For bleeding, note when it began, how it is changing, and whether you have cramps, dizziness, fever, or shoulder-tip pain. A clinician may discuss observation, medication, or a procedure depending on the examination and scan. Read about [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/).

Seek urgent medical care for heavy or rapidly increasing bleeding, severe or one-sided abdominal pain, fainting, marked dizziness, fever, or feeling acutely unwell. These symptoms need assessment because bleeding in pregnancy can have several causes, including an ectopic pregnancy.

Ask what dose of vitamin C is appropriate for you, whether your symptoms need an ultrasound or blood tests, and which changes should prompt an urgent review. If a loss is confirmed, ask which management option fits your symptoms, scan findings, and preferences.
