During pregnancy, caffeine intake should not exceed moderate levels. Green tea is a source of caffeine. If you are or might be pregnant, consult your health care provider for advice about caffeine intake. Caffeine can pass to your infant through breast milk; if you consume high levels of caffeine, it can lead to symptoms such as fussiness and poor sleep patterns in your infant.
Green tea is a popular beverage that can offer several health benefits. It is packed with antioxidants especially epigallocatechin gallate (EGCG) that can decrease inflammation. The tea can also protect against chronic disease, reduce cancer risk, improve skin health, and enhance longevity.
It can significantly boost heart health by reducing blood pressure and cholesterol. The drink improves cognitive function, enhances memory & boosts focus. Green tea can significantly support weight management plans as it can enhance fat burning when paired with workouts.
However, in some cases, the drink can do more harm than good especially if consumed by some individuals facing health conditions. The presence of caffeine, tannins, and bioactive compounds in the tea can cause some side-effects or interfere with medical conditions.
Individuals With Caffeine Sensitivity: The tea contains caffeine and individuals with caffeine sensitivity may experience restlessness, headache, and irritability. If you are consuming other sources of caffeine during a day, adding green tea may boost the overall intake of caffeine and may end up worsening the symptoms.
Individuals With Iron Deficiency: Green tea has compounds namely tannins that can interfere with iron absorption from plant-based foods. Individuals suffering from deficiency of iron or anemia should avoid consuming green tea especially after meals.
Pregnant Women: Pregnant and breastfeeding women should keep a vigil eye to their caffeine intake. Moderate consumption of the beverage may not pose any health hazards but excess intake of caffeine can cause potential side effects and risks. Green tee contains compounds that can impact folate metabolism which is significant during pregnancy. Probably, this is the reason why pregnant ladies must consult their healthcare professionals before including large amounts of the beverage.
According to a report featured in National Center for Complementary and Integrative Health, “During pregnancy, caffeine intake should not exceed moderate levels. Green tea is a source of caffeine. If you are or might be pregnant, consult your health care provider for advice about caffeine intake. Caffeine can pass to your infant through breast milk; if you consume high levels of caffeine, it can lead to symptoms such as fussiness and poor sleep patterns in your infant.” 1
Individuals With Heart Conditions: For some individuals, consumption of caffeine-loaded drinks can surge the heart rate or cause palpitations. Individuals experiencing heart rhythm disorders or facing sensitivity to stimulants may face discomfort post drink tea consumption. Therefore, they should limit their green tea intake or opt for decaffeinated beverages.
Individuals Taking Some Specific Medications: Green tea can interfere with some particular medications such as blood thinners, stimulants, or medications for blood pressure or heart disease. The presence of some compounds in the drink can impact the functioning of these medications. It is significant to consult your doctor prior to introducing the beverage to the daily routine.
Individuals With Sensitive Stomach: It is never advisable to sip green tea on empty stomach as it can cause discomfort or irritability to individuals with stomach sensitivity. The presence of natural compounds in the tea can surge acid production in the stomach thus causing nausea or digestive problems. Individuals with acid reflux likely to benefit from green tea consumption post meals instead of empty stomach.
Dr. Saurabh Sethi, AIIMS-trained gastroenterologist and liver specialist, also educated at Harvard and Stanford, took to his Instagram account and highlighted 7 worst tea habits. He said overdoing green tea extracts has been linked to rare but real liver toxicity. 2

People suffering from insomnia or sleep issues should avoid or limit the green tea intake. They can also avoid green tea around evenings or late night. Dr Sethi said late night chai or green tea is yet another harmful tea habit as caffeine lingers for hours that can disrupt sleep, which your liver needs to repaid. 2
