What is Matcha?

Matcha is a type of green tea powder  made from shade-grown Camellia sinensis tea leaves. Growing matcha in the shade enhances its flavor and increases the concentration of amino acids and chlorophyll, giving it that nice, vibrant green color. The tea leaves are steamed, dried, and stone-ground into a fine powder to release more antioxidants, L-theanine, and other bioactive compounds. 

Matcha has been used in traditional Japanese tea ceremonies for hundreds of years. We’re proud to continue the tradition. 

Is Matcha Bad For You?

When consumed in moderation as a part of a balanced diet, matcha is generally considered safe and therapeutic for the majority of people. A small number of people can be sensitive to some of the ingredients in matcha and may experience minor, unpleasant side effects. Even when you drink too much matcha, the worst possible side effects you may experience are stomach discomfort and potential caffeine-related symptoms.

Highly nutritious and beneficial  adaptogenic superfoods like matcha can help you manage stress and promote your physical and mental energy levels. This is because matcha is high in  L-theanine, an amino acid known for its relaxing and calming effects. L-theanine can promote a state of relaxation without inducing drowsiness and help counterbalance the potential jitters or anxiety sometimes associated with caffeine consumption.  Hidese, et. al. reveal that “L-theanine has the potential to promote mental health in the general population with stress-related ailments and cognitive impairments.”

Other major active components in matcha are catechins. Catechins are a type of flavonoid known for their potent antioxidant properties. The most well-known is epigallocatechin gallate (EGCG).  Research reveals that “...epigallocatechin gallate is the most effective antioxidant polyphenol against hydrogen peroxide and radical-scavenging activity.” 

Matcha tea contains more beneficial molecules, like:

  • Chlorophyll: matcha’s green pigment is known for its detoxifying properties.
  • Theophylline: a naturally occurring compound that may have beneficial impacts on respiratory health.
  • Tannins: polyphenolic antioxidants that give the astringent taste to green teas. 
  • Fiber: dietary fibers in matcha aid in digestion, help regulate blood sugar levels, and contribute to a healthy gut.
  • Vitamins and minerals: vitamin C, vitamin A, vitamin E, and B complex. Matcha Is also rich in potassium, calcium, iron, and magnesium.

Because of its rich chemical composition, the effects of matcha on our health are diverse.

  1. Matcha’s catechins, most notably epigallocatechin gallate, have been associated with potential cardiovascular benefits. These compounds may help reduce the risk of heart disease by regulating blood pressure, improving cholesterol profiles, and supporting endothelial function, which is crucial for maintaining the health of blood vessels. According to  research, EGCG can regulate nitric oxide synthesis and help treat inflammatory vascular and cardiovascular disorders. 
  2. L-theanine is known for its calming, anti-stress effects. This amino acid promotes relaxation without making you feel drowsy. 
  3. Matcha is also beneficial for the brain. EGCG may have neuroprotective effects that support brain health and normal cognitive functioning.
  4. Some studies suggest that matcha's high antioxidant content may support liver health. According to a  2021 study, antioxidants in matcha may help reduce liver damage caused by non-alcoholic fatty liver disease. The active components of matcha seem to control lipid buildup and inflammation and boost liver function. 
  5. Polyphenols in matcha have potential anticancer properties. Catechins, such as EGCG, have shown promising effects in laboratory studies, including inhibiting tumor growth, preventing cancer cell proliferation, and inducing cancer cell death. 
  6. Antioxidants contribute to skin health. The catechins and other antioxidants in matcha help neutralize free radicals, which can cause skin damage and aging. Drinking matcha can help keep your skin nourished and fresh, prevent dryness, and give you a healthy, glowing complexion.

Does Matcha Have Caffeine?

Caffeine is a naturally occurring stimulant in matcha. According to research, matcha contains more caffeine than other types of green tea and coffee. 

Matcha has a relatively high caffeine content compared to other green teas, which gives it a unique aroma and flavour. The content of caffeine in green teas was found to fall within the range of 11.3–24.67 mg/g, while in matcha it amounted to between 18.9 and 44.4 mg/g. For the sake of comparison, most coffee beans will contain 10.0–12.0 mg caffeine/g of beans. (Kochman, et. al.)

Caffeine has the potential to give you nervous energy when consumed in excessive amounts. Fortunately,  matcha’s caffeine is less likely to cause jitters.

A  2021 study found that the caffeine in matcha can help improve cognitive performance and focus. Regular matcha consumption resulted in improved task performance and boosted attention in senior adults. 

The matcha group showed an increase in the amount of work after continuous intake… Ingesting matcha with caffeine improves both attention and work performance when suffering from psychological stress compared with caffeine alone.

Unlike other sources of caffeine, matcha contains L-theanine. The combination of caffeine and L-theanine gives you a sustained and more balanced boost in energy and focus without the jitters typically associated with caffeinated beverages.

See our comparison of coffee and matcha to learn how matcha’s caffeine provides a more sustainable lift.

What Happens If You Drink Too Much Matcha?

When you drink too much matcha, you’re also consuming a fairly high amount of caffeine. High caffeine content can produce the following effects:

  • While matcha’s caffeine and L-theanine provide a sustained energy boost and increased alertness, too much of it can make you feel overstimulated, overly energized, jittery, and anxious. 
  • Excessive amounts of matcha can result in typical caffeine-related symptoms, such as:
    • Increased heart rate
    • Heart palpitations
    • High blood pressure
    • Feelings of restlessness
  • An upset stomach and digestive problems may also result from drinking too much matcha. Matcha is rich in tannins, which can potentially cause digestive discomfort and mild abdominal pain if consumed in high doses. 
  • If you drink too much matcha later in the day or before you go to bed, it may interfere with your sleep patterns and make you too overstimulated to sleep.
  • Because of L-theanine,  matcha has anti-anxiety properties that help relieve stress and promote relaxation. However, the combination of caffeine and other energy-boosting compounds in matcha can potentially trigger symptoms of anxiety or nervousness in people sensitive to stimulants, especially if you’re drinking too much matcha. 
  • As a natural diuretic, matcha increases urine production. If you drink too much of it and not enough water, it can potentially lead to dehydration. Stay hydrated, no matter how many cups of matcha you drink. 

Caffeine sensitivity varies from person to person. The majority of people can enjoy matcha as part of a balanced diet without experiencing negative effects. Some may feel more alert and energetic, while others may be more sensitive to caffeine's effects and feel restless and agitated.

The secret to never experiencing any negative side effects from too much matcha is moderation. 

How Much Matcha Is Too Much?

One to two cups of matcha in a single day is just enough to give you a sustained and longer-lasting energy boost. Too much matcha is anything above 4–5 grams of matcha powder per day—that’s one of  our matcha packets, each of which contains 3.5 grams of matcha deliciousness. 

Individual tolerances to caffeine do vary, but if you’ve never had matcha before, try to stick to lower amounts and work your way up. This way, you’ll avoid the negative effects of consuming too much caffeine. 

How Much Matcha Can I Drink Every Day?

The recommended daily consumption of matcha is between 2 and 4 grams of matcha powder. That amount can yield anywhere from one to even four cups of matcha tea, depending on how strong you take your tea. If you’re a beginner, start with smaller amounts. Once your body adjusts to the beneficial effects of matcha, you can drink more cups per day. 

Each of  our cordyceps matcha sachets contains the recommended daily amount of matcha (3.5g). You don’t need spoons or measuring scoops—empty one packet into a mug, pour in hot water, use  our magic matcha wand to stir until nice and frothy, and enjoy the ultimate matcha experience. 

Is It Okay to Drink Matcha Every Day?

There is no reason why you shouldn’t indulge in a nice cup of premium quality matcha tea every day if you stick to the recommended daily amounts. The myriad health benefits and nutrient-rich profile make it an excellent supplement to any diet. 

Who Should Avoid Matcha?

While matcha is healthy for most people, there are people who are sensitive to caffeine or who have medical conditions such as hypertension, heart problems, or adrenal gland abnormalities. Before drinking matcha, consult with a healthcare professional.

Despite the high caffeine content in matcha,  some pregnant or nursing women are okay with small amounts of caffeine here and there. It's generally recommended that they limit their caffeine intake to 200 milligrams per day, which is approximately one to two cups of coffee. That’s equivalent to two soothing cups of matcha tea if you’re using  our 10-pack matcha sachets (and you really should).

Benefits of Drinking Matcha In the Morning

The best time to have matcha is in the morning or early afternoon. Matcha will provide an energetic boost that can get you through the day. Drinking matcha tea later in the day or right before bed can make you feel a bit too overstimulated to sleep. 

Since  cordyceps mushrooms should also be consumed earlier in the day, the best time to  drink our mushroom matcha tea is in the morning, just around breakfast. One delicious cup will keep you up and running throughout the day. 

With  our electric magic wand, whipping up your matcha tea has never been easier (or quicker).

Matcha FAQ

Is it bad to drink matcha tea every day?

Drinking matcha tea every day is not bad for your health. In fact, matcha green tea is beneficial as long as it is consumed in moderation and as part of a balanced diet.  Matcha contains a ton of antioxidants, including catechins like EGCG. 

Excessive intake of matcha, like with other caffeinated beverages, may lead to side effects such as increased heart rate, jitteriness, or sleep disturbances in individuals sensitive to caffeine. Listen to your body and adjust your matcha intake based on your tolerance and overall health.

Do Japanese drink matcha every day?

Matcha is the most popular drink in Japan, where some people drink it every morning instead of coffee. Matcha is an essential part of Japanese culture, particularly the traditional custom of Japanese tea ceremonies. Many individuals in Japan enjoy matcha as part of their daily routine, whether in the form of traditional tea ceremonies or modern preparations like matcha lattes and other culinary applications.

Is 4 teaspoons of matcha too much?

Four teaspoons of matcha may provide a higher caffeine content than is optimal for most people. While individual tolerances do vary, it’s best if you stick to 1–2 tablespoons in a single day for a sustained and longer-lasting energy boost. Consuming matcha in moderation is unlikely to cause any potential side effects. 

When should I stop drinking matcha?

If you’re experiencing unpleasant side effects from matcha, like heart palpitations, an upset stomach, or anxiety, stop drinking it. If the side effects persist for more than two days, consult your healthcare professional. 

Drinking matcha every day typically has no adverse effects, but the high caffeine content may cause some mild effects. Avoid drinking matcha in the evening or before bed, as it may interfere with your sleep. 

Is matcha better with water or milk?

Matcha tea can be made with milk or water, and the choice between the two depends entirely on your personal preferences and dietary choices. Traditional matcha preparation involves whisking matcha powder with hot water, which results in a vibrant, frothy tea with a distinct flavor. Many people also enjoy matcha lattes, where they mix matcha powder with milk or a plant-based alternative. Adding milk can provide a creamier and milder taste. 

Is matcha good for the skin?

Matcha's antioxidant properties can contribute to skin health. Catechins in matcha help neutralize free radicals, which can cause skin damage and aging. Matcha’s anti-inflammatory effects reduce redness and skin irritation. According to  research, chronic inflammation plays a role in a variety of skin disorders, including acne, eczema, and psoriasis. Green tea’s polyphenols provide protection from UV radiation, and while it isn’t a replacement for sunscreen, sipping a cold matcha latte may provide additional UV protection on a hot day.

Is matcha a superfood?

Matcha is often regarded as a superfood due to its rich nutritional profile and potential health benefits. It is packed with antioxidants, vitamins, minerals, and amino acids. Matcha's antioxidant content, particularly EGCG, is higher than that of regular brewed green tea. 

While matcha offers many potential health benefits, it's essential to maintain a balanced diet, engage in a healthy lifestyle, and not rely solely on one specific food or ingredient for overall well-being.

Does matcha have bad side effects?

Long-term consumption of matcha does not have negative side effects unless you drink way too much of it. On the contrary, matcha has a ton of health benefits. 

Each person may have a different tolerance for matcha and its components. Factors such as overall health, caffeine sensitivity, and personal reactions can influence individual responses. Listen to your body and adjust your matcha intake accordingly. Try to choose high-quality matcha from reputable sources only, such as Hone.

Does matcha tea stain teeth?

Dental experts say that  matcha doesn’t stain your teeth directly, but it can stain the plaque on your teeth. You can prevent this by brushing twice per day to remove the plaque before it turns to tartar.  

Matcha is extremely beneficial to your oral health. It contains natural chemicals with antibacterial characteristics, which can help eliminate dental plaque, cavities, and bad breath.  Vyas, et. al. found that catechins suppress bacterial growth in the mouth, while polyphenols in matcha can also help eliminate bad breath and boost general oral hygiene. 

Research also suggests that  matcha green tea may prevent the development of oral cancer by inhibiting the growth of cancer cells. 

Is it OK to drink matcha on an empty stomach?

Drinking matcha on an empty stomach is generally well-tolerated by most people. A small percentage of people may experience mild discomfort or digestive issues. 

If you discover that drinking matcha on an empty stomach doesn't agree with you, try having a snack first. This can help alleviate any stomach discomfort and provide a more comfortable matcha experience. 

Do matcha and green tea come from the same plant?

Matcha and regular green tea come from the same tea plant, called Camellia sinensis. The difference between these two types of tea is in the processing method and the way tea leaves are prepared. 

Green tea leaves are steamed or pan-fried, which helps preserve their green color and natural compounds. The leaves are then dried and can be brewed to make green tea. 

Matcha is made from shade-grown tea leaves. Before harvesting, the tea plants are covered for several weeks to increase chlorophyll production and enhance the leaves’ flavor and color. After harvesting, they are steamed, dried, and ground into a fine tea powder, which is then whisked with water to create matcha tea.

Other tea types also come from Camellia sinensis, like black teas, white teas, and oolong teas. 

Is matcha OK before bed?

Drinking matcha before going to bed is generally not recommended. Matcha contains caffeine, a stimulating ingredient that can keep you up at night or affect the quality of your sleep. Caffeine typically remains in your system for several hours, so beverages like coffee and matcha before bed aren’t a smart choice. 

That’s one of the many reasons why matcha is best consumed earlier in the day, in the morning or early afternoon. 

Is matcha healthier hot or cold?

Matcha can be enjoyed both hot and cold. The choice between the two depends on your personal preference. The nutritional composition and potential health benefits of matcha remain relatively consistent, regardless of temperature. 

When matcha is prepared hot, the heat helps extract the flavors and nutrients from the powdered tea. The hot water also enhances the natural aroma and taste of matcha. Cold matcha beverages, such as iced matcha lattes or matcha smoothies, offer a refreshing and cooling option, especially during warmer weather or when seeking a chilled beverage.

Is matcha stronger than coffee?

The strength of matcha and coffee can be measured in different ways. In terms of caffeine content, matcha generally contains more caffeine per serving than coffee. However, due to the unique combination of caffeine and other compounds, matcha provides a more balanced and sustained energy boost compared to coffee. 

Ultimately, the choice between matcha and coffee depends on your personal taste, desired effects, and unique tolerance to caffeine. We are team  matcha mushroom tea through and through.
