The Benefits & Risks of Drinking Green Tea for Your Kidneys

Green tea has long been recognized for its various health benefits. It may have a positive effect on many systems in the body, including the kidneys. However, drinking green tea could also potentially harm your kidneys in certain circumstances.

Advantages of Drinking Green Tea for Kidneys

Research suggests that drinking a moderate amount of green tea per day might have some benefits for your kidneys. Here are some of the potential advantages to drinking green tea for this organ:

  • Reduced risk of kidney stones: Green tea may help reduce the risk of developing kidney stones, due to its diuretic properties.
  • Increased filtration rate: Green tea has been found to increase the glomerular filtration rate, which is important for kidney function.
  • Antioxidant protection: Green tea contains antioxidants, which can help protect the organs of your body, including the kidneys.

Disadvantages of Drinking Green Tea for the Kidneys

Drinking green tea can also have some undesirable consequences on your kidneys, such as:

  • Increased caffeine intake: Too much caffeine from green tea can cause damage to the kidneys.
  • Dehydration: Green tea is a diuretic, which means it causes you to lose more moisture than you take in. This could lead to dehydration, which is bad for your kidneys.
  • Liver damage: Drinking too much green tea can also potentially damage the liver, which could have a negative effect on the kidneys.


Green tea may have some beneficial effects on the kidneys. However, it is important to drink in moderation to avoid the potential risks. If you are concerned about drinking green tea and its effects on your kidneys, it is best to speak to your doctor.
