Why Does Green Tea Make Me Nauseous Explained

Green tea has gained popularity worldwide due to its numerous health benefits. However, some individuals may experience nausea after consuming green tea. In this article, we will explore the potential causes of this discomfort and provide strategies to help alleviate it.

Understanding Green Tea:

Green tea is derived from the Camellia sinensis plant and is known for its high concentration of antioxidants called catechins. These compounds offer various health benefits, including reducing inflammation and promoting heart health.

Possible Causes of Nausea:

  1. Caffeine sensitivity or intolerance:
    Green tea contains caffeine, which acts as a stimulant. Some individuals may have a sensitivity or intolerance to caffeine, leading to symptoms such as nausea. Caffeine can stimulate gastric acid secretion, which may cause stomach discomfort.
  2. Tannin content:
    Tannins are natural compounds found in tea, including green tea. They contribute to the tea’s astringency and bitter taste. However, high levels of tannins can lead to feelings of queasiness or stomach discomfort, especially in sensitive individuals.
  3. Other potential factors:
    Green tea also contains other compounds that might contribute to digestive issues, such as polyphenols and theanine. Additionally, individual differences and personal sensitivities can play a role in experiencing nausea after consuming green tea.

Coping Strategies and Solutions:

  1. Reduce caffeine intake:
    If you suspect caffeine is the cause of your nausea, consider opting for decaffeinated green tea or tea blends with lower caffeine content. This can help reduce the stimulating effects on the stomach.
  2. Adjust brewing methods:
    Experiment with shorter brewing times and slightly lower water temperatures when preparing green tea. This can help minimize the extraction of tannins, which may reduce the likelihood of experiencing nausea.
  3. Pair green tea with food:
    Consuming green tea alongside a light snack or meal can aid digestion and potentially alleviate nausea. The presence of food in the stomach can help buffer the effects of tea on the digestive system.

Seeking Professional Advice:

If you experience persistent or severe nausea after consuming green tea, it is advisable to consult a healthcare professional. They can help identify any underlying causes and provide personalized recommendations based on your specific situation. Consider discussing your symptoms with a doctor or registered dietitian.


While green tea offers numerous health benefits, some individuals may experience nausea after consuming it. This can be due to caffeine sensitivity, tannin content, or other factors. By reducing caffeine intake, adjusting brewing methods, or pairing green tea with food, individuals can potentially alleviate the discomfort. It’s important to listen to your body, try different strategies, and seek professional advice if needed. With these considerations in mind, you can continue to enjoy the benefits of green tea while minimizing any potential discomfort.
