Matcha it contains caffeine and polyphenolic compounds that affect the digestive system, so its consumption in case of gastric reflux requires a conscious approach and quantity control. Reflux is the backflow of stomach contents into the esophagus, which leads to burning, discomfort and irritation of the mucous membrane. Symptoms may be exacerbated by excessive relaxation of the lower esophageal sphincter and increased secretion of hydrochloric acid. Matcha, as a drink containing caffeine, may influence these mechanisms, but its effect differs from coffee due to the presence of L-theanine and lower acidity. The quality of the product, the method of preparation and the moment of consumption are of key importance. Properly used matcha can also be part of the diet for people with reflux, provided that rules limiting gastrointestinal irritation are followed.

Does caffeine worsen reflux symptoms?
Caffeine may affect the tone of the lower esophageal sphincter, which in some people leads to worsening of reflux symptoms. This mechanism involves relaxing the muscle separating the esophagus from the stomach, which promotes the regurgitation of food contents. In the case of matcha, the caffeine content is moderate and spread over time thanks to the presence of L-theanine, which limits sudden stimulation of the nervous system. Compared to coffee, matcha has lower acidity, which reduces the risk of irritation of the gastric mucosa. The body's reaction is individual, so people with reflux should monitor their tolerance even with small amounts. Consuming matcha on an empty stomach may increase discomfort, so it is better to combine it with a light meal.
Matcha and gastric acid secretion
Green tea affects the secretion of gastric juice, but this effect is milder than in the case of strong coffee. Polyphenols present in matcha affect the gastrointestinal mucosa and in moderate amounts do not cause significant irritation. High quality of the raw material is crucial, because lower quality may be associated with more noticeable bitterness and greater discomfort. Water temperature also affects tolerance - pouring boiling water increases the extraction of compounds responsible for bitterness and may intensify the burning sensation. In case of reflux, it is especially important to avoid very hot drinks, which further irritate the esophagus. Appropriate preparation technique limits the potential for irritation.

How to drink matcha for reflux?
People with reflux should use smaller portions of matcha, usually about 1 gram of powder per 150 ml of water, and avoid consumption on an empty stomach. Drinking it after a light meal reduces the risk of stomach irritation. The temperature of the drink should be in the range of 70-80°C to limit excessive extraction of bitter compounds. It is also worth monitoring the total amount of caffeine from other sources, as accumulation may worsen symptoms. Pure matcha without added sugar and syrups is a better choice than sweetened latte drinks, which increase the burden on the stomach. Individual observation of the body's reaction allows you to adjust the amount to your own tolerance.
When to give up matcha?
In case of severe symptoms of reflux, esophageal erosions or active inflammation of the mucous membrane, it is worth limiting all drinks containing caffeine. If even a small amount of matcha causes discomfort, its consumption should be stopped until the symptoms stabilize. Treatment of reflux includes dietary modification, weight loss and pharmacological therapy, therefore the functional drink does not replace medical recommendations. The priority remains to protect the mucosa and reduce factors that increase the regurgitation of gastric contents. A conscious approach and control of the body's reactions determine the safety of consumption.
