Caution: Green Tea Extract Can Be Harmful on an Empty Stomach

Green tea is widely praised for its detoxifying and antioxidant properties, and when enjoyed in moderation, it can be a healthy part of your daily routine. However, the concentrated form, green tea extract, can pose serious risks, especially when taken on an empty stomach.

Often found in weight loss pills and “fat-burning” supplements, green tea extract contains high levels of catechins, the active compounds responsible for many of its benefits. But in large amounts, these catechins can turn toxic. When the extract is taken without food, its absorption increases significantly, which can put extra stress on your liver.

Research and case reports have linked high doses of green tea extract to liver injury. Warning signs of liver stress or damage include dark-colored urine, persistent fatigue, and discomfort or pain in the upper right side of your abdomen, right where your liver sits.

If you’re already drinking green tea regularly, your body is likely getting enough of its beneficial compounds. Adding a concentrated supplement on top of that may not only be unnecessary, it could be harmful.

Tip: If you choose to take green tea extract, make sure it’s under the guidance of a healthcare provider, and never on an empty stomach.
