Drinking matcha on an empty stomach has become a popular morning habit for those seeking an energy boost and health benefits. Matcha green tea typically contains more antioxidants than regular green tea and can have a higher caffeine concentration, depending on preparation, making it an appealing alternative to drink coffee. Many people drink matcha before breakfast to support metabolism, enhance focus with L-theanine, and promote digestion.


Some studies suggest that consuming matcha early in the day may aid in weight loss and provide essential nutrients without adding excessive calories. However, matcha intake on an empty stomach may not be suitable for everyone, as it can sometimes cause stomach cramps or nausea.

Is It Safe to Drink Matcha on an Empty Stomach?

Drinking matcha on an empty stomach affects people differently. Some experience an energy boost and improved focus, while others may develop stomach cramps or nausea due to matcha’s caffeine content and tannins. These compounds can increase stomach acid, leading to digestive issues for sensitive individuals.


Matcha green tea also contains L-theanine, which helps balance caffeine’s effects, but those unaccustomed to high caffeine intake may still feel discomfort. Clinical nutrition experts suggest consuming matcha with or after a meal to avoid digestive upset, though many people tolerate it well before breakfast.

Benefits of Drinking Matcha on an Empty Stomach

Drinking matcha in the morning offers several potential benefits, from supporting metabolism to enhancing focus. Consuming matcha before a meal allows the body to absorb nutrients quickly, maximizing its effects.

Enhanced Metabolism

Matcha contains compounds that have been studied for their potential effects on metabolism, though individual results may vary. A study published in the American Journal of Clinical Nutrition found that green tea extract can boost thermogenesis, a process that helps burn calories for energy. While matcha is a type of green tea, more research is needed to confirm its specific effects.


This effect, combined with regular exercise and a healthy diet, may aid in weight loss. Unlike sugary drinks or high-calorie coffee beverages, a cup of matcha provides a naturally low-calorie option for those looking to manage their weight.

Improved Mental Focus

Drinking matcha delivers a steady energy boost without the jittery effects of coffee. The combination of caffeine and L-theanine in matcha green tea promotes alertness while reducing stress. Caffeine enhances concentration, while L-theanine encourages a calm but focused state, making matcha a beneficial morning drink for productivity. Many people drink matcha instead of coffee to sustain their energy levels without sudden crashes.

Antioxidant Boost

Matcha contains a higher concentration of antioxidants than regular green tea, helping protect cells from oxidative stress. These antioxidants, particularly catechins, help combat oxidative stress and support overall health. Drinking matcha on an empty stomach allows the body to absorb these beneficial compounds efficiently. Antioxidants also play a role in reducing inflammation, which is essential for long-term wellness.

Risks of Drinking Matcha on an Empty Stomach

Drinking matcha before eating isn’t ideal for everyone. Some people may experience digestive issues or caffeine-related side effects. Choosing high-quality matcha green tea and moderating matcha intake can help reduce risks.

Stomach Sensitivity

Matcha contains tannins and caffeine, which can increase stomach acid and cause discomfort in some individuals. Drinking matcha on an empty stomach may lead to:


  • Nausea – Tannins can irritate the stomach lining, causing an unsettled feeling.

  • Acid Reflux – Higher acid production may trigger symptoms in those with acid reflux.

  • Upset Stomach – Some people experience mild stomach cramps after consuming matcha.

  • Digestive Discomfort – Sensitive individuals may feel bloating or gas.

Caffeine Overload

Matcha has a higher concentration of caffeine than regular green tea, which may cause jitters or an energy crash in caffeine-sensitive individuals. Drinking matcha on an empty stomach allows caffeine to be absorbed quickly, which can lead to nervousness, rapid heartbeat, or disrupted digestion. People who drink coffee regularly may tolerate caffeine well, but those unaccustomed to it should start with a smaller matcha intake. Matcha can be consumed with food or milk to reduce potential side effects to slow caffeine absorption.

Low-Quality Matcha Concerns

Not all matcha powder is the same. Low-quality matcha often contains additives, artificial sweeteners, or excess fillers, which may cause unwanted reactions. Some store-bought matcha products, including flavored matcha drinks, may contain added sugar, which could reduce potential health benefits. Consuming high-quality, pure matcha ensures better taste, higher antioxidant content, and fewer artificial ingredients that could impact digestion or overall health.

Who Should Avoid Drinking Matcha on an Empty Stomach?

Some individuals should be cautious about drinking matcha first thing in the morning. Certain health conditions or lifestyle factors may increase the risk of side effects when consuming matcha on an empty stomach.


  • People with Acid Reflux – Matcha can increase stomach acid, triggering heartburn.

  • Those with Caffeine Sensitivity – High caffeine content may cause jitters or insomnia.

  • Individuals Taking Certain Medications – Some medications interact with caffeine or antioxidants, reducing their effectiveness.

  • Anyone with Stomach Ulcers – Matcha’s acidity may worsen symptoms.

  • Pregnant or Nursing Individuals – High caffeine intake should be moderated.

  • People Prone to Low Blood Pressure – Some studies suggest that matcha may lower blood pressure, which could be problematic for those already low levels.

How to Drink Matcha on an Empty Stomach Without Discomfort

Drinking matcha on an empty stomach can be enjoyable with a few simple adjustments. Making small changes to matcha intake can help reduce digestive discomfort while providing an energy boost and health benefits.

Start with a Smaller Serving

Drinking a full cup of matcha on an empty stomach may be too intense for some people. Starting with a smaller serving, such as half a teaspoon of matcha powder mixed with hot water, allows the body to adjust.


This gradual approach helps prevent nausea, stomach cramps, or caffeine sensitivity while still providing the potential benefits of matcha green tea. Slowly increasing the amount over time can help improve tolerance.

Use High-Quality Matcha

Low-quality matcha often contains additives, has a bitter taste, and may cause digestive issues. High-quality, ceremonial-grade matcha is smoother, richer in antioxidants, and less acidic, making it gentler on the stomach.


Choosing pure matcha green tea without artificial sweeteners or fillers ensures better absorption of nutrients while avoiding unnecessary additives found in some store-bought options like Starbucks matcha drinks.

Pair with a Light Snack

Pairing matcha with a light snack can help those prone to stomach sensitivity. Eating a few nuts, a banana, or a small bowl of oatmeal before drinking matcha may reduce acidity and prevent nausea. A light meal helps slow caffeine absorption, making matcha intake more balanced. Adding milk or a natural sweetener can also soften the taste and make it easier to digest.

Best Time to Drink Matcha Tea for Optimal Benefits

Drinking matcha at the right time can maximize its effects. While some people enjoy matcha on an empty stomach, others may benefit more from consuming it after a meal.

Morning Ritual Benefits

Matcha is a great alternative to drink coffee in the morning, offering a steady energy boost without jitters. The combination of caffeine and L-theanine promotes focus and alertness, making it an excellent addition to a mindful morning routine. Drinking matcha in the morning may help with focus and provide antioxidants, but individual effects can vary.

Balancing Mid-Morning and Afternoon Energy

For those sensitive to caffeine or prone to digestive issues, drinking matcha after breakfast or lunch may be a better option. Consuming matcha mid-morning or early afternoon helps sustain energy levels throughout the day without disrupting sleep. Matcha’s caffeine content is absorbed more gradually than coffee, preventing sudden crashes and providing long-lasting benefits.

Nutritional Breakdown of Matcha

Matcha green tea contains beneficial nutrients, including antioxidants, vitamins, and amino acids. It contains catechins, a powerful antioxidant that supports overall health, and caffeine and L-theanine for sustained energy. Matcha also provides essential vitamins like vitamin C, vitamin A, and B-complex vitamins, which contribute to immune support and metabolism.


Matcha offers a more balanced energy release than coffee due to its unique combination of caffeine and L-theanine. While coffee provides a quick caffeine spike, matcha promotes focus without sudden crashes. Matcha is rich in antioxidants, which may support overall health, making it a beneficial addition to a balanced diet.

Is Drinking Matcha on an Empty Stomach Right for You?

Drinking matcha on an empty stomach offers benefits like enhanced metabolism, increased energy, and a rich source of antioxidants, but it may also cause stomach sensitivity or caffeine-related discomfort in some people. Those who tolerate matcha well may enjoy its potential benefits before breakfast, while others may need to consume it with food to avoid nausea or acid reflux.


The best approach is to start with a smaller serving, choose high-quality matcha green tea, and listen to how your body responds. Adjusting matcha intake and timing based on individual tolerance ensures the best experience.
