Why is Matcha Acid Reflux Friendly?

Matcha: friend or foe for acid reflux?

This trendy Japanese green tea boasts a health halo. Yet, if you suffer from burning heartburn and unwanted burps, you might wonder – is matcha a safe sip or a recipe for disaster?

Fear not, fellow reflux warriors!

I’ve dug deep into several researches, to answer your burning question: is matcha bad for acid reflux? 

So grab a comfy mug, settle in, and let’s sip on the truth!

Key Takeaways

  • Matcha can be GERD-friendly, but it’s personal. Start slow and see how your stomach reacts.
  • Matcha’s stress-busting compounds, like L-theanine, might calm your LES and prevent acid reflux.
  • Matcha’s slow-release caffeine won’t trigger heartburn like regular coffee.
  • Listen to your body! If it’s not happy, don’t force it.
  • Baby steps! Slowly increase the amount if you tolerate it well.

Let’s Begin by Understanding Acid Reflux

Acid reflux, or GERD as it’s also called, is like a splash of stomach acid back up into your esophagus, the tube that connects your mouth to your tummy. This acid can cause a burning feeling in your chest and throat, no fun!

A bunch of factors may cause stomach acid to backflip. 

1. Weak LSE (Lower Sphincter Muscle)

Sometimes, the muscle that keeps the acid in your stomach called the LES, isn’t as strong as it should be. This can happen because of:

2. Stress & the Acid Reflux

Stress has turned out as the main culprit behind this acid backflip as it releases certain chemicals like cortisol. These chemicals increase stomach acid production and keep the weak LSE relaxed.

3. Low Stomach Acid

Just like high stomach acid, low stomach acid may also mess with the LES and keep it relaxed even after eating food, leading to acid reflux. It’s like trying to hold a door shut with just your pinky finger! 

4. Nutritional Deficiencies

Missing out on important nutrients like calcium, vitamin B12, or magnesium can also make the LES a bit wobbly. Think of it like not having enough bricks to build a strong wall.

Other things that can give acid reflux the green light include:

  • Slow digestion
  • Hiatal hernia, which is when your stomach squeezes through a gap in your diaphragm (the muscle between your chest and belly)
  • Pregnancy (thanks, hormones!)
  • Certain medications
  • Being overweight
  • Spicy food, fatty food, and big meals (think Thanksgiving dinner!)
  • Smoking and alcohol

Basically, acid reflux can be caused by a mix of things. But figuring out what’s causing your reflux can help you manage it (in my case, it was chronic stress that elevated cortisol levels and interrupted the normal function of LES). So you can return to enjoying all the good stuff in life without the heartburn party.

Understanding Match and its Bio-Chemical Compounds

Matcha is Japanese powdered green tea made from finely ground, shade-grown Camellia Sinensis tea leaves called tencha. It’s rich in chemical compounds like catechins, L-theanine, caffeine, chlorophyll, and vitamins and minerals. These compounds contribute to its unique flavor and several health benefits.

To understand whether matcha can be OK when suffering from GERD, it’s essential to know about the chemical compounds it has. 

Here is a list of them:

1. Catechins 

Matcha’s secret weapon? Antioxidants are called catechins, with EGCG (epigallocatechin gallate) as their champion. These ninja warriors fight inflammation, guard your heart, and even boost your brain. 

But what about their effect on your stomach?

EGCG has a positive impact on your stomach in the following ways.

  • Considering the anti-inflammatory effect of catechins, matcha consumption can reduce inflammation and soothe the LES to prevent acid reflux.
  • Studies suggest EGCG has a calming influence on this stress hormone. It does this by calming the adrenal glands and reducing cortisol production. Lower stress makes LSE work efficiently and prevents acid reflux.

However, EGCG might slightly increase stomach acid. But don’t worry, it’s a gentle nudge, not a full-on fire blast. This might even help with digestion, but more research is needed to brew the perfect cup of certainty.

2. L-theanine

L-theanine, matcha’s calming amino acid, might be your new best friend for both relaxation and gut health. It teams up with caffeine for a smooth energy boost and helps your body absorb matcha’s antioxidants better. But does it irritate your stomach?

Studies suggest L-theanine might actually help prevent or heal ulcers caused by stress or meds like aspirin. Its antioxidant and anti-inflammatory properties could be the secret weapon. It might even help with GERD, thanks to its cortisol-lowering and sleep-improving effects.

However, a tiny increase in stomach acid production has been observed in healthy people. But it was small and probably not enough to cause problems.

Remember, individual factors like your usual stomach acidity and overall health can influence how L-theanine affects you.

3. Slow Releasing Caffeine

Matcha has slow-release caffeine in it to boost your mind function without causing GERD, unlike regular caffeine that worsens GERD.

4. Chlorophyll

This green machine detoxes and fights inflammation, giving matcha its vibrant color and earthy taste. Besides this, it also indirectly contributes to cortisol regulation by reducing stress and inflammation, which are linked to elevated cortisol and decreased LES functioning.

5. Fiber

It keeps your digestion happy and your gut healthy. Bonus points for matcha!

6. Vitamins and Minerals

Matcha has a treasure trove of these guys, like vitamin K for strong bones, vitamin A for good vision, and mood-boosting magnesium.

7. Alkaline Nature

Matcha is naturally alkaline; it can help neutralize stomach acid, potentially reducing heartburn and GERD symptoms. Think of it like a gentle counterbalance to the acid in your tummy.

What Has GERD Sufferers Got to Say about Matcha?

Matcha consumers on Amazon have vowed that matcha has not aggravated their acid reflux symptoms.

As reviewer Miriam put it on April 8, 2021,

I love the fresh energy without the crash or acid reflux and I especially love to pour it over ice after using my frother, a fine sieve and milk….

Another reviewer,  Natasha F, on September 1, 2020, loved matcha for its lack of acidity, saying,

…This is a great alternative for me to coffee because coffee irritates my acid reflux; matcha doesn’t.

(You can study the reviews by many other customers, filtering them for words like “acid” or “reflux” here.)


Matcha is one of the healthiest energy kicks packed with good stuff for your body and mind. Its slow-release caffeine paired with catechins and L-theanine has positive effects on relieving stress and inflammation, which could be the primary cause of acid reflux. Besides this, these compounds also have a positive effect on stomach acid. 

Yet, some studies suggest that matcha’s concentrated caffeine might temporarily increase stomach acid, especially when consumed on an empty stomach. This could worsen GERD symptoms for some people.

How Should You Start with Matcha with Acid Reflux?

Match can be good with acid reflux. Yet, it’s best to start with small quantities, as everybody is different.

Here are a few tips to start with benefiting yourself from matcha’s wonders:

Individual Sensitivity

Everyone reacts to matcha differently. Some with GERD find it helpful, while others experience flare-ups. Pay attention to your body’s response.

Start Tiny

Think of your tummy like a shy date. A small, plain matcha sip is the perfect “hello.” No fancy lattes with sugar and milk—those are just acid reflux triggers in disguise.

Preparation Matters

Matcha lattes with sugar and milk can be a no-go for GERD. Try plain matcha tea or whisked with water for a gentler approach.

Timing is Key

Avoid matcha right before bed or on an empty stomach. Give it some space after meals to prevent acid spikes.

Listen to your Body

We’re all unique butterflies, and matcha affects us differently. Pay attention. If your stomach is upset or you experience acid reflux, stop right there. Don’t force it—there are plenty of other GERD-friendly teas out there.

Go Plain Jane

Skip the flavored powders and syrups. Those additives can be your reflux’s worst nightmare. Stick to pure matcha whisked with water for a gentle introduction.

Baby Steps

If tiny sips feel good, gradually increase the amount. Rushing things is like inviting heartburn to the party. Slow and steady wins the GERD race.


Matcha has good stuff—antioxidants, stress-fighters—that might help your GERD in the long run. But it’s all about finding your sweet spot. Be patient, experiment, and listen to your tummy.


It’s important to note that while the studies mentioned here paint a promising picture, they were not directly sponsored by matcha producers and may have limitations. They primarily analyze how individual bio-compounds in matcha affect health and don’t definitively recommend matcha consumption for GERD. While the results are encouraging, more extensive, independent research is needed to confirm these findings and establish clear guidelines for matcha’s role in acid reflux management.
