Cinnamon is a popular spice that has been used for thousands of years in traditional medicine and culinary practices. It is made from the inner bark of several tree species, and is used in many different dishes, including desserts, hot beverages, and curries. However, there are some myths and misconceptions surrounding the use of cinnamon, particularly when it comes to its effects on pregnancy. In this article, we will explore the question: can cinnamon cause a miscarriage?

Does Cinnamon Cause Miscarriage? The Myth
There is a long-standing belief in some cultures that cinnamon can cause a miscarriage, and this has led to some women avoiding cinnamon during pregnancy out of fear that it might harm their unborn child. However, we could not find good scientific evidence that cinnamon used in normal food amounts causes a miscarriage. The US National Institutes of Health says studies suggest cinnamon is safe in pregnancy in the amounts commonly found in foods (NCCIH).
Is Cinnamon Safe During Pregnancy?
Cinnamon used as a spice in normal food amounts is likely safe during pregnancy. NCCIH notes that some studies suggest both Ceylon and cassia cinnamon are safe in pregnancy in amounts commonly found in foods, but Ceylon cinnamon in larger amounts during pregnancy is considered unsafe (NCCIH). So skip cinnamon supplements, capsules and essential oils unless your doctor has said they are fine.
Why Is Cinnamon Linked to Miscarriage?
Part of the worry comes from traditional medicine, where cinnamon has long been used for many conditions, including period problems. Some people take this to mean it could affect the womb, but we did not find good human evidence that cinnamon in food does this. There is a separate, real caution: cassia cinnamon (the common, cheaper type) contains coumarin, and some cassia products are high in it. Large amounts or long-term use may be a problem, especially for people with liver disease, and cinnamon supplements can interact with some medicines (NCCIH).
What Does the Research Say?
Research on cinnamon in pregnancy is limited. NCCIH says research does not clearly support using cinnamon for any health condition, and it is unclear whether cinnamon supplements help with diabetes (NCCIH). If you have gestational diabetes, follow the plan from your doctor or diabetes team rather than taking cinnamon as a treatment.
Cinnamon in Food vs. Supplements
It is important to note that while cinnamon is considered safe for consumption during pregnancy, it is always best to consult with a healthcare provider before taking any supplements or making significant changes to your diet. This is particularly important if you have any underlying health conditions or if you are taking any medications, as cinnamon may interact with certain drugs.
The Bottom Line
In conclusion, there is no good evidence that cinnamon in normal food amounts causes a miscarriage, and it is likely safe in pregnancy as a spice. Larger amounts (such as supplements or concentrated oils) are a different matter, so avoid them unless your doctor says otherwise. If you have any concerns about your diet or the use of supplements during pregnancy, it is always best to speak with a healthcare provider.
