Matcha and Coffee: Digestive Effects Compared

Quick answer

• Both matcha and coffee can stimulate bowel movements.
• Coffee’s caffeine is a known laxative for many.
• Matcha’s caffeine and L-theanine might also aid digestion, but less predictably than coffee.
• Fiber in whole matcha powder could contribute to regularity.
• Individual reactions vary wildly. What works for one person might not for another.
• Both can cause stomach upset if you’re sensitive.

Key terms and definitions

• Caffeine: A natural stimulant found in coffee beans and tea leaves. It speeds up the central nervous system and can increase gut motility.
• L-Theanine: An amino acid found primarily in tea. It’s known for promoting relaxation and focus, and may have some digestive effects.
• Gut Motility: The movement of food through your digestive tract. Stimulants can increase this.
• Laxative Effect: The tendency of a substance to promote bowel movements.
• Digestive Tract: The series of organs responsible for breaking down food.
• Irritable Bowel Syndrome (IBS): A common disorder affecting the large intestine, causing cramping, abdominal pain, bloating, gas, diarrhea, or constipation.
• Stomach Upset: General discomfort in the stomach, which can include nausea, bloating, or pain.
• Fiber: Indigestible plant material that adds bulk to stool, aiding regularity.
• Antioxidants: Compounds that fight free radicals in your body. Both coffee and matcha are rich in these.
• Acidity: The pH level of a substance. Coffee is more acidic than matcha, which can affect some people’s stomachs.

How it works

• Coffee’s Caffeine Kick: Coffee’s caffeine acts as a stimulant. It tells your colon to get moving, increasing contractions. This is a pretty direct pathway to the bathroom for many.
• Coffee and Bile: Coffee also seems to trigger the release of bile from your gallbladder. Bile helps digest fats, but it can also speed things up in your intestines.
• Matcha’s Caffeine: Matcha, being powdered green tea, also contains caffeine. It’s absorbed a bit differently than coffee’s caffeine, often leading to a smoother, more sustained energy boost.
• L-Theanine’s Role: The L-theanine in matcha might play a subtle role. It can calm the nervous system, which could indirectly influence gut function, though it’s not a primary driver of bowel movements.
• Fiber in Matcha: Unlike brewed tea, you’re consuming the whole matcha leaf. This means you get dietary fiber. Fiber is a big player in keeping things regular.
• Gastrin Release: Some research suggests coffee can increase the release of gastrin, a hormone that stimulates stomach acid and bowel activity. Matcha’s effect here is less pronounced.
• Gut Microbiome: Both beverages can interact with your gut bacteria, though the long-term effects are still being studied. A healthy microbiome is key for good digestion.
• Hydration: Both drinks contribute to your fluid intake, which is essential for preventing constipation.

What affects the result

• Brewing Method: How you make your coffee or matcha matters. Espresso is concentrated, drip coffee is different, and whisked matcha is whole leaf.
• Grind Size (Coffee): Finer grinds in coffee can sometimes extract more compounds, potentially influencing digestive effects.
• Amount of Coffee/Matcha: More caffeine means a stronger potential effect. Simple as that.
• Your Personal Sensitivity: This is huge. Some folks can drink espresso and feel nothing, others need a decaf. Same with matcha.
• Water Temperature: For matcha, hotter water can sometimes extract more bitter compounds. For coffee, it affects extraction too.
• Freshness of Beans/Powder: Stale coffee or matcha might have slightly different chemical profiles.
• What Else You’ve Eaten: Having coffee or matcha on an empty stomach versus after a meal can change how your body reacts.
• Additives: Milk, sugar, or cream can alter how your stomach processes the drink. Dairy can be an issue for some.
• Time of Day: Your body’s natural rhythms can influence digestive responses.
• Hydration Levels: Being dehydrated can make any digestive stimulant less effective or even cause discomfort.
• Existing Digestive Issues: If you have IBS or a sensitive stomach, you’ll likely notice effects more.
• Caffeine Tolerance: Regular coffee drinkers might build up a tolerance to its laxative effects.

Pros, cons, and when it matters

• Coffee Pro: Reliable laxative effect for many. Gets things moving when you need it.
• Coffee Con: Can cause jitters, anxiety, or stomach upset due to acidity and high caffeine.
• Coffee Pro: Rich in antioxidants. Good for you in moderation.
• Coffee Con: Can disrupt sleep if consumed too late in the day.
• Coffee Con: Might worsen acid reflux for some people.
• Matcha Pro: Smoother, sustained energy without the crash coffee can bring.
• Matcha Pro: Contains L-theanine, which promotes calm focus.
• Matcha Pro: You consume the whole leaf, meaning more fiber and nutrients.
• Matcha Con: Less predictable as a laxative compared to coffee.
• Matcha Con: Can still cause stomach upset in sensitive individuals.
• Matcha Con: Quality varies wildly. Bad matcha tastes… well, bad.
• When it Matters: If you’re looking for a guaranteed morning bathroom visit, coffee is usually your go-to. If you want gentle energy and potential digestive support without the strong laxative punch, matcha might be better.

FAQ

Does matcha make you poop like coffee?

Not usually with the same intensity. Coffee’s caffeine is a more direct and potent laxative for most people. Matcha might offer some digestive benefits due to its fiber and caffeine, but it’s less of a guaranteed trip to the restroom.

Can coffee cause diarrhea?

Yes, for many people, coffee’s stimulant effect can lead to loose stools or diarrhea, especially if consumed on an empty stomach or in large quantities.

Is matcha good for your gut?

Matcha contains fiber and antioxidants, which are generally beneficial for gut health. However, its direct impact on bowel movements is less pronounced than coffee’s.

Will drinking matcha upset my stomach?

It can, especially if you’re sensitive to caffeine or new to drinking it. Start with a smaller amount to see how your body reacts.

Does the type of coffee matter for digestive effects?

Yes. Espresso, drip coffee, cold brew – they all have different caffeine levels and extraction processes, which can influence how they affect your digestion.

How much caffeine is in matcha versus coffee?

A typical 8 oz cup of brewed coffee has about 95 mg of caffeine. An 8 oz matcha latte (made with 1-2 tsp of matcha powder) usually has around 60-80 mg.

What’s the best way to drink coffee to avoid stomach upset?

Try drinking it with food, opt for a darker roast (which can be less acidic), or consider cold brew, which is often smoother on the stomach.

Can I drink both matcha and coffee?

You can, but be mindful of your total caffeine intake. Too much caffeine from any source can lead to jitters, anxiety, and digestive issues.

What if I have IBS, should I avoid coffee or matcha?

It depends on your specific triggers. Many people with IBS find coffee exacerbates symptoms. Matcha might be a gentler alternative, but it’s best to test small amounts and see.
