Green tea is widely celebrated for its antioxidants, calming ritual, and potential health benefits. But if you suffer from acid reflux or GERD (Gastroesophageal Reflux Disease), you may wonder whether green tea helps or hurts your symptoms.
The answer isn’t entirely straightforward.
For some people, green tea may offer anti-inflammatory benefits that support digestive health. For others, the caffeine and natural compounds found in green tea may trigger or worsen acid reflux symptoms.
In this guide, we’ll explore the relationship between green tea and acid reflux, what the research says, and how to determine whether green tea is a good choice for your individual situation.
Green tea may be soothing for some people, but its caffeine content can trigger acid reflux symptoms in others.
Quick Navigation
What Is Acid Reflux?
Acid reflux occurs when stomach acid flows backward into the esophagus.
Normally, a muscular valve called the lower esophageal sphincter (LES) prevents stomach contents from moving upward. When this valve weakens or relaxes improperly, stomach acid can irritate the lining of the esophagus.
Common symptoms include:
- Heartburn
- Chest discomfort
- Sour taste in the mouth
- Chronic cough
- Hoarseness
- Difficulty swallowing
Occasional acid reflux is common, but frequent symptoms may indicate GERD.
What Makes Green Tea Unique?
Green tea comes from the leaves of the Camellia sinensis plant and undergoes minimal oxidation during processing.
As a result, it contains high concentrations of beneficial plant compounds, including:
- Catechins
- Polyphenols
- Antioxidants
- L-theanine
- Small amounts of caffeine
These compounds contribute to many of green tea’s well-known health benefits.

Green tea contains naturally occurring antioxidants, catechins, and L-theanine that contribute to its unique character.
Can Green Tea Help Acid Reflux?
Some evidence suggests that green tea may provide certain benefits for digestive health.
Antioxidant Support
Green tea contains catechins, powerful antioxidants that may help reduce oxidative stress and inflammation throughout the body.
Potential Anti-Inflammatory Effects
Research has suggested that compounds found in green tea may help reduce inflammation in the digestive tract and esophagus.
Because inflammation often contributes to discomfort associated with acid reflux, these compounds may provide support for some individuals.
A Calming Ritual
Many tea drinkers find that slowly sipping tea encourages mindful eating and relaxation, both of which may indirectly support digestive comfort.
Why Green Tea May Trigger Acid Reflux in Some People
While green tea offers many benefits, it also contains compounds that may worsen reflux symptoms in certain individuals.
Caffeine Can Relax the LES
Caffeine may relax the lower esophageal sphincter, making it easier for stomach acid to move into the esophagus.
Tea Acidity
Green tea is less acidic than many beverages, but it still contains natural acids that may irritate an already sensitive digestive system.
Individual Sensitivity Varies
Some people tolerate green tea without issue, while others notice increased heartburn.
Green tea affects individuals differently. Some people find it soothing, while others may notice increased reflux symptoms.
Is Decaffeinated Green Tea Better for Acid Reflux?
For many people, yes.
Decaffeinated green tea allows you to enjoy many of green tea’s beneficial compounds while minimizing the potential reflux-triggering effects of caffeine.
Tips for Drinking Green Tea With Acid Reflux
- Drink tea with food
- Avoid drinking on an empty stomach
- Limit quantity
- Avoid late-night tea
- Consider lower-caffeine varieties such as hojicha
