The Surprising Link Between Green Tea Extract and Kidney Stones

Green tea is renowned for its health benefits, from boosting metabolism to reducing the risk of heart disease. But did you know that consuming green tea extract in large quantities can also increase your risk of developing kidney stones?

Kidney stones are small, hard deposits of mineral and acid salts that form inside the kidneys. They can cause severe pain and discomfort, and can even lead to kidney damage if left untreated. But what causes these stones to form in the first place?

One of the main risk factors for kidney stones is a high intake of oxalates. These are naturally occurring compounds found in many foods, including green tea. When oxalates are consumed in large amounts, they can bind with calcium in the urine to form crystals, which can then grow into larger stones.

Green tea extract, which is often used as a dietary supplement, contains high concentrations of oxalates. Studies have found that taking green tea extract supplements can increase the amount of oxalates in the urine, potentially leading to the formation of kidney stones.

However, it’s important to note that not everyone who drinks green tea or takes green tea extract supplements will develop kidney stones. Factors such as genetics and overall health also play a role. Additionally, moderate consumption of green tea (3 cups or less per day) is not likely to cause kidney stones.

But if you’re prone to kidney stones or have a history of them in your family, it’s best to be cautious and limit your intake of green tea extract. Speak with your doctor or a dietitian to determine what’s safe for you.
