Does Green Tea Make You Poop? 3 Questions About Tea and Bowel Movements, Answered

But the caffeine and certain added ingredients can lead to toilet troubles — in other words, green tea may make you poop.

Does Green Tea Make You Poop?

The short answer is yes, green tea can make you poop.

One potential culprit: Caffeine. It's a bitter substance that occurs naturally in plants like tea leaves, per the U.S. National Library of Medicine (NLM). Caffeine stimulates your central nervous system to make you feel more awake. But for some people, the caffeine in coffee or tea also makes you poop, per the International Foundation for Gastrointestinal Disorders (IFFGD).

Although green tea doesn't have as much caffeine as coffee, it still contains some, ranging from 14 to 60 milligrams per 8-ounce cup (compared to 95 to 200 milligrams per cup of coffee).

While tea and matcha do make you poop sometimes, it can also be the ingredients you add to your drink that are to blame for your trip to the bathroom. For instance, adding artificial sweeteners like sorbitol can trigger diarrhea for some people, according to the IFFGD. And making your tea with milk or cream may likewise cause diarrhea if you have lactose-intolerance-symptoms-adults/' target='_blank' rel='noopener noreferrer' >lactose intolerance.


To avoid symptoms of too much caffeine, limit yourself to 400 milligrams per day, according to the U.S. Food & Drug Administration.

Does Green Tea Cause Constipation?

It's possible that green tea does help with constipation. But can the reverse also be true?

In short, likely not — there's no evidence to show that a cup of green tea can cause constipation.

That said, certain products made from the tea (like green tea extract) may lead to constipation, along with other digestive issues like abdominal discomfort and nausea, according to the National Institutes of Health's Office of Dietary Supplements.

Does Green Tea Turn Your Poop Green?

If you notice dark green stool after a run to the toilet, you may be wondering what causes green poop.

While there's no evidence to suggest that drinking plain tea can lead to green feces or dark green diarrhea, it's possible that matcha can make your poop green, according to the Cleveland Clinic.

But why, exactly, does matcha make your poop green? Well, the chlorophyll that gives plants (including tea leaves) their color can have the same effect on your stool. This is why vegetables like broccoli, kale and spinach can turn poop green, too.

The added food dyes in prepackaged bottles of tea could be another reason why tea makes you poop green, according to the Cleveland Clinic.
