Is Rooibos Tea Safe During Pregnancy?
Partly: Plain rooibos tea may be an option during pregnancy if your prenatal clinician agrees, because it is naturally caffeine-free, but its pregnancy safety has not been established. The available pregnancy-specific research is limited and includes animal studies, so it cannot define a safe amount for pregnant people.
rooibos tea is an herbal infusion made from the rooibos plant. Being caffeine-free is useful when limiting caffeine during pregnancy, but it does not prove that all of the drink’s other plant compounds are safe during pregnancy.
What is the short answer?
Ask your obstetrician, midwife or other prenatal clinician before making rooibos tea a regular part of your routine. There is not enough human pregnancy evidence to say confidently that any particular amount is safe throughout pregnancy.
If you have already had a cup, the lack of definitive safety evidence does not mean that harm has occurred. Mention it to your prenatal clinician if you are concerned, and ask for advice before continuing.
The distinction matters because “not known to be harmful” and “proven safe” are different things. A clinician can help you weigh the uncertainty against your health history, medications and the particular product you want to drink.
Why is pregnancy safety uncertain?
Plain rooibos tea naturally contains no caffeine, so it does not add caffeine to your intake. That is one reason someone might consider it during pregnancy. Still, caffeine is only one consideration: rooibos also contains plant compounds, and their effects during human pregnancy have not been adequately established.
A 2023 study in rats examined maternal exposure to red rooibos during pregnancy and lactation. It found no change in the measured bone development of the offspring. The study looked at a particular outcome in rats; it did not establish that rooibos tea is safe for pregnant people or rule out other effects.
A 2021 rat study examined maternal bone changes with red rooibos exposure around pregnancy and lactation. It also cannot establish a pregnancy-safe amount for humans. Neither study provides a basis for using rooibos tea to improve pregnancy outcomes.
Products can differ too. A package labeled as rooibos may contain other herbs, flavorings or caffeinated ingredients, and evidence about plain rooibos cannot automatically be applied to a blend. Concentrated extracts and supplements are also different products from a brewed cup of tea.
How much rooibos tea is safe during pregnancy?
There is no established pregnancy-safe number of cups of rooibos tea. Avoid treating a serving suggestion on a package, or someone else’s experience, as a medically verified limit. The animal studies do not tell us how much a pregnant person can safely drink.
If your prenatal clinician agrees that you can drink rooibos tea, show them the product and discuss how often you intend to have it. Choose a plain product whose ingredient list identifies rooibos, rather than assuming that every rooibos blend is caffeine-free or suitable for pregnancy.
Prepare the tea with safe drinking water in a clean cup, following the package directions. Do not assume that a stronger brew, concentrated rooibos extract or herbal supplement has the same safety profile as an ordinary infusion. Ask your clinician before using those products, too.
Rooibos tea should not replace regular meals, a prescribed prenatal vitamin or other care recommended during pregnancy. If you are having trouble drinking enough fluids or keeping them down, contact your prenatal care team rather than relying on an herbal drink to solve the problem.
When should you talk to your doctor?
Check with your prenatal clinician before drinking rooibos tea if you have liver disease, anemia, a pregnancy complication or an allergy to an ingredient in the product. Also ask if you take prescription medicines, including blood thinners, or supplements such as iron. This is a precaution, not a claim that rooibos necessarily interacts with every medication.
Bring the package or ingredient list to the conversation, especially if the product is a blend. Tell your clinician how much you have been drinking and how often, and mention any symptoms or concerns. Do not stop or change prescribed medication without their advice.
Seek urgent maternity care for vaginal bleeding, severe abdominal pain, a severe headache, vision changes or reduced fetal movements. These symptoms need assessment regardless of whether you have had rooibos tea. Seek emergency help immediately for trouble breathing or swelling of the lips or tongue, which can be signs of a serious allergic reaction.
Frequently asked questions
Is red rooibos safer than green rooibos during pregnancy?
There is not enough human pregnancy evidence to establish that either type is safer. The animal studies discussed here used red rooibos.
Does an organic label make rooibos tea safe during pregnancy?
An organic label does not establish pregnancy safety. Check the ingredient list and discuss the product with your prenatal clinician.
Can rooibos tea replace a prenatal vitamin?
No. Rooibos tea is not a substitute for a prenatal vitamin or other supplements recommended by your prenatal clinician.
