Is Green Tea Bad for Your Kidneys?

Green tea has become increasingly popular in recent years for its potential health benefits, including its potential to improve kidney health. But does green tea really have this effect, or could it cause harm to your kidneys? Let’s take a look.

Potential Benefits of Green Tea

Green tea has been found to contain compounds which may be beneficial to kidney health. These compounds include:

  • Catechins – natural antioxidants which may reduce inflammation in the body and improve blood flow to the kidneys.
  • Epicatechin – an antioxidant which may help protect against kidney damage.
  • Theanine – an amino acid which studies show may improve the elimination of waste in the kidneys and protect against damage.

Does Green Tea Harm the Kidneys?

Fortunately, there is no evidence that green tea is bad for your kidneys. In fact, studies suggest green tea may actually have a beneficial effect on kidney health. However, drinking very large amounts of green tea can cause harm, as it contains caffeine. High levels of caffeine can cause headaches and insomnia, and if consumed in excess, may lead to kidney damage over time.


Overall, green tea may be beneficial to your kidneys, thanks to its many compounds. However, it is not recommended to drink large amounts of green tea, as it contains caffeine which can cause harm in large doses. For those looking to reap the potential benefits of green tea, moderate consumption (1 – 2 cups a day) is suggested.

Happy Brewing!
