What You'll Learn
Caffeine content
Caffeine is a stimulant that can freely cross the placenta and enter the baby's bloodstream. As a result, doctors often recommend limiting caffeine intake to less than 200 mg per day during pregnancy, or even avoiding it altogether. This includes all sources of caffeine, such as tea, coffee, soft drinks, chocolate, and energy drinks.
Green tea contains caffeine, but in smaller amounts than coffee. On average, an 8-ounce cup of green tea contains 24 to 45 milligrams of caffeine, depending on the brand and brewing method. Brewed iced green tea might contain more caffeine than a regular cup.
While green tea is generally considered safe to consume during pregnancy, it is important to limit caffeine intake. One to three cups of green tea per day is generally considered safe, but it is important to monitor overall caffeine consumption to stay below the recommended limit.
To reduce caffeine intake, pregnant women can opt for decaffeinated versions of green tea, although these still contain small amounts of caffeine. They can also reduce the caffeine content by steeping the tea for a shorter time, as caffeine is the first substance released during the steeping process.

Health benefits
While the evidence against caffeine during pregnancy is not conclusive, doctors recommend limiting caffeine intake to less than 200 mg per day or even avoiding it altogether. Green tea typically contains about 24 to 45 mg of caffeine per 8-ounce cup, depending on the brand and brewing method. This means that one to three cups of green tea per day are generally considered safe.
Green tea is often praised for its health benefits. It is mostly water and contains almost no calories per cup. It is made from the same plant as regular black tea and contains caffeine, but in smaller amounts. Here are some of the health benefits of green tea:
- Rich in antioxidants: Green tea contains high concentrations of antioxidants called polyphenols, which fight free radicals in the body and prevent them from damaging DNA in your cells.
- Improved metabolism: Green tea is one of the most effective drinks for improving metabolism. However, during pregnancy, it is important to avoid consuming green tea for burning fat as it can negatively impact the mother's nutritional intake and the fetus's necessary energy for growth.
- Lower risk of cancer: The antioxidants in green tea may also help lower the risk of cancer.
- Boosted brain function: Green tea is known for its potential ability to boost brain function.
- Support for the immune system: Green tea contains nutrients that support the immune system.
- Aid in weight loss: Green tea is often praised for its ability to aid in weight loss. However, this could be detrimental during pregnancy, as it may prevent the body from retaining necessary nutrients.
- Heart health: Green tea may help prevent heart disease.
While green tea has many potential health benefits, it is important to consume it in moderation during pregnancy due to its caffeine and EGCG content. High blood pressure during pregnancy can lead to complications such as preeclampsia and hypertensive disorders. Additionally, EGCG, an active ingredient and powerful antioxidant in green tea, can affect the body's folate metabolism, which is essential during pregnancy to prevent neural tube defects in the fetus.

Safety concerns
While green tea is generally considered safe to consume during pregnancy, there are some safety concerns to be aware of.
Firstly, green tea contains caffeine, a stimulant that can freely cross the placenta and enter the baby's bloodstream. Caffeine may increase the risk of miscarriage, stillbirth, or preterm birth, and infants exposed to high levels of caffeine in utero may have a lower birth weight or birth defects. While some research suggests that low levels of caffeine are safe during pregnancy, the American College of Obstetricians and Gynecologists (ACOG) recommends limiting caffeine intake to less than 200 mg per day. Green tea typically contains about 24-45 mg of caffeine per 8-ounce cup, but this can vary depending on the brand and brewing method. Therefore, it is important to monitor your overall caffeine intake if you choose to drink green tea during pregnancy.
Secondly, green tea contains high concentrations of epigallocatechin gallate (EGCG), a potent antioxidant that may inhibit the absorption of folate. Folate is essential during pregnancy to prevent neural tube defects in the fetus. Therefore, excessive consumption of green tea may negatively impact fetal growth and development.
Thirdly, herbal teas, which are often recommended during pregnancy as caffeine-free alternatives, may also carry risks. Certain herbs can have side effects for both mother and baby, and some teas may stimulate the uterus and cause miscarriage if consumed in large amounts. Pregnant people should particularly avoid herbal laxative teas, as these can cause dehydration and electrolyte imbalances.
Lastly, green tea pills are not considered safe during pregnancy due to their potential impact on metabolism and nutrient absorption.
In summary, while green tea is generally considered safe during pregnancy when consumed in moderation, it is important to be aware of the potential risks associated with caffeine and EGCG intake, as well as the risks associated with herbal and dietary tea blends. As always, it is best to consult with a healthcare professional for personalized advice and to ensure that green tea is safe for your individual circumstances.

Recommended intake
While green tea is generally considered safe during pregnancy, it is important to monitor your intake. Green tea contains caffeine, which can freely cross the placenta and enter the baby's bloodstream. As your pregnancy progresses, your body's ability to break down caffeine slows down. Excessive caffeine intake during pregnancy has been linked to an increased risk of miscarriage, stillbirth, and preterm birth, as well as low birth weight and birth defects.
Most health organizations recommend limiting caffeine intake to less than 200 mg per day during pregnancy. This includes caffeine from all sources, such as coffee, tea, soft drinks, chocolate, and energy drinks. Since an 8-ounce cup of green tea typically contains 24 to 45 mg of caffeine, it is important to limit your consumption accordingly. One to three cups of green tea per day is generally considered safe during pregnancy.
To reduce your caffeine intake, you can opt for decaffeinated green tea, although it may still contain small amounts of caffeine. Another method is to control the brewing process by steeping the tea for a shorter time or using the same tea bag for multiple cups.
In addition to caffeine, green tea contains high concentrations of antioxidants called polyphenols, which offer potential health benefits for pregnant women. However, green tea also contains epigallocatechin gallate (EGCG), a potent antioxidant that can affect the body's folate metabolism. Folate is essential during pregnancy to prevent neural tube defects in the fetus. Therefore, excessive consumption of green tea may negatively impact the absorption of folate, so moderation is crucial.
It is always recommended to consult with your doctor or healthcare provider to determine the safe intake limit for green tea during pregnancy, as individual circumstances may vary.

Herbal alternatives
While herbal teas are often praised for their health benefits, there is limited research on their safety during pregnancy. The Food and Drug Administration (FDA) does not regulate herbal teas, and most have not been studied for safety in pregnant people. Certain herbs can have side effects for both mother and baby, and excessive consumption of some herbal teas may stimulate the uterus and cause a miscarriage.
However, some herbal teas are generally considered safe to consume during pregnancy. These include:
- Raspberry leaf: Rich in iron, raspberry leaf tea helps tone the uterus, increase milk production, decrease nausea, and ease labour pains. It is also believed to help prevent pregnancies from pre- or post-term gestation. However, some healthcare providers recommend only consuming it after the first trimester.
- Peppermint leaf: This herb is helpful in relieving nausea/morning sickness and flatulence.
- Ginger: This herb is commonly used to ease morning sickness during pregnancy, and many studies have concluded that it is safe and effective for this purpose. However, the National Center for Complementary and Integrative Health notes that the evidence of safety is not conclusive, so it is important to discuss ginger's benefits and risks with a healthcare provider before consuming it.
It is always best to consult a healthcare provider before consuming any herbal teas during pregnancy, as they can provide guidance on which teas are safe and help monitor overall caffeine intake.
