Can Vitamin C Cause Miscarriage?

Introduction: Can Vitamin C Cause Miscarriage?

Vitamin C is an essential nutrient known for its numerous health benefits, particularly its role in immune function and collagen synthesis. However, when it comes to the topic of pregnancy, concerns may arise about the potential effects of vitamin C consumption on the risk of miscarriage. In this article, we will examine the relationship between vitamin C and miscarriage, providing insights based on available research and expert opinions.

Understanding Miscarriage

Miscarriage, also known as spontaneous abortion, is the loss of a pregnancy before the 20th week. It is estimated that approximately 10-20% of known pregnancies end in miscarriage, often occurring within the first trimester. While the causes of miscarriage can be multifactorial and complex, they are generally attributed to genetic abnormalities, hormonal imbalances, uterine abnormalities, or maternal health conditions.

Vitamin C and Pregnancy

Vitamin C plays a crucial role in supporting overall health, including reproductive health. During pregnancy, adequate intake of vitamin C is essential for the proper development of the fetus and maternal well-being. It helps in the formation of collagen, which is necessary for the growth and repair of tissues in both the mother and the developing baby. Additionally, vitamin C supports the immune system, aids in iron absorption, and has antioxidant properties that protect against oxidative stress.

Can Vitamin C Cause Miscarriage?

There is limited scientific evidence suggesting that vitamin C, when consumed within the recommended daily allowances, is not associated with an increased risk of miscarriage. In fact, maintaining adequate levels of vitamin C during pregnancy is important for the prevention of various complications.

Strikingly, a study published in the American Journal of Obstetrics and Gynecology examined the association between dietary intake of vitamin C and the risk of miscarriage in over 11,000 pregnant women. The study found no evidence that vitamin C intake, even at high levels, increased the risk of miscarriage. Similarly, other studies investigating the effects of vitamin C on reproductive outcomes did not find a significant correlation between vitamin C supplementation and an elevated risk of miscarriage.

Benefits of Adequate Vitamin C Intake during Pregnancy

  1. Collagen Synthesis: Adequate vitamin C is essential for the synthesis of collagen, a protein important for the development of fetal tissues, including blood vessels, bones, and skin.
  2. Immune Support: Vitamin C supports immune function, helping to protect both the mother and the developing fetus from infections and illnesses.
  3. Antioxidant Properties: Vitamin C acts as an antioxidant, neutralizing harmful free radicals that can cause oxidative stress. This is particularly important during pregnancy, as oxidative stress has been implicated in pregnancy complications.
  4. Iron Absorption: Vitamin C enhances the absorption of iron, another essential nutrient during pregnancy. Sufficient iron levels are necessary for the production of healthy red blood cells and the prevention of iron-deficiency anemia.

Consultation with a Healthcare Professional

While scientific evidence suggests that vitamin C, when consumed within recommended levels, does not increase the risk of miscarriage, it is important to consult with a healthcare professional, especially if you have concerns or specific medical conditions. A healthcare professional can evaluate your individual circumstances and provide personalized recommendations based on your unique needs.


Based on the current scientific literature, there is no evidence to suggest that vitamin C consumption within recommended levels increases the risk of miscarriage. In fact, adequate intake of vitamin C is essential for a healthy pregnancy, supporting fetal development, immune function, collagen formation, and antioxidant protection. It is crucial to maintain open communication with your healthcare provider and follow their recommendations to ensure a safe and healthy pregnancy.
