What are the negative effects of green tea?

The Dark Side of Green Tea

Green tea is often touted as a miracle drink, with numerous health benefits and antioxidants that can help reduce the risk of cancer and heart disease. But did you know that green tea also has some negative effects on the body?

While it’s true that green tea is packed with antioxidants and other beneficial compounds, drinking too much of it can have some unwanted side effects. Here are just a few of the downsides to consider before reaching for that next cup of green tea.

Caffeine Content

Green tea contains caffeine, which can cause jitteriness, anxiety, and even insomnia in some people. If you’re sensitive to caffeine or have trouble sleeping, it’s best to avoid green tea or limit your intake to the morning or early afternoon.

Stomach Upset

Green tea can also cause stomach upset in some people, particularly if it is consumed on an empty stomach. This can lead to nausea, vomiting, and diarrhea. To avoid stomach upset, it’s best to drink green tea with meals or snacks.

Interaction with Medications

Green tea can also interact with certain medications, making them less effective. For example, it can reduce the absorption of iron from supplements and non-meat sources. If you take any medications, it’s important to talk to your doctor about the potential interactions with green tea.


While green tea has many health benefits, it’s important to be aware of its potential downsides. If you’re sensitive to caffeine, have trouble sleeping, or take medications, green tea may not be the best choice for you. And even if you don’t have any of these concerns, be sure to drink green tea in moderation to avoid stomach upset and other negative effects.
