Best Time to Drink Matcha? What Happens if You Drink too much Matcha?

We get it, matcha makes you feel amazing, and you want to know just how much you can drink, right? Well, while we hope to help get you there, maybe you’re not quite there yet. 

Perhaps then you’re curious before getting into matcha, just how much can you drink? There are many common questions, including what happens if you drink too much matcha, or what side effects there may be.

Some are also curious whether the caffeine in matcha is stronger than coffee? Here we review the most important things to be aware of as you make your matcha choice, while we also put some myths to rest.

Hopefully, these answers instead help to encourage more regular enjoyment of matcha tea. In fact, as the science supports – multiple servings per day.

Is there such a thing as a matcha overdose?

If this has crossed your mind, relax. While it’s recommended to discuss matcha usage with your physician, it’s good to know there are no known dangers of drinking too much matcha.

Besides the infrequent report of a short-lived upset stomach, researchers are confident that the strongest preparations of matcha tea, even when enjoyed multiple times per day, pose no known risks. 

Matcha and Liver Health Debunking

That said, one common concern is whether matcha is a danger to your liver. The good news is that no, matcha is not known to damage the liver, or any other organs when consumed as a whole-leaf powder [1]. 

Often people in this case are concerned whether EGCG, a catechin antioxidant found in green tea, could be associated with liver damage.

  • Nope! According to numerous publications, including the official report from the European Food Safety Authority, it’s demonstrated that there are no general risks of matcha green tea, or any green tea infusion [1].

While it’s true that excessive doses from synthetic green tea concentrates may be of concern, that does NOT include matcha green tea.

  • Matcha is not a green tea concentrate. It is a natural, traditional preparation of green tea only.  

Too Much Matcha Caffeine? Potential Too Much Matcha Side Effects?

One of the next most common concerns of having too much matcha, is whether it’s possible to overdo it on the caffeine. Again, the short answer is no.

  • A single serving has about one-third the caffeine content of your average cup of coffee.
  • Matcha tea also contains a range of stimulating compounds, not only caffeine, which ultimately act to create a balanced reaction when ingested.

These include the methylxanthine compounds, and the stress-reducing complex of amino-acids such as arginine and L-theanine. This diverse range of healthy stimulating compounds help explain the day-long energy, and side-effect free boost of focus.

Furthermore, it’s estimated according to FDA guidelines that you would need to consume more than 10 servings of matcha tea every day before being over the recommended limit of caffeine.

So, rather than ask how much is too much, why not shift gears to find out how much is best? Two cups per day? Three cups per day? What benefits of matcha tea you’re interested in could very well decide. 

Effective dose of Matcha Tea | How much Matcha for Health Benefits

Matcha is safe to enjoy in quantity each day, but what function does quality play in expected health benefits? As it turns out, quality can be a big determinant; certain qualities in fact speak to dedicated health benefits. 

It’s known that the range of qualities, or “Grades” of matcha green tea actually represent chemical differences in the matcha powder, influencing the specific ways that your body’s health benefits from this tea. 

The Matcha health benefits that interest you most can help make a determination of which matcha to choose, and how much to drink each day.

  • A 2018 study determined that of 67 samples of matcha tea tested outside of Japan, only one possessed prominent stress-reducing properties, due to the reduced amino-acids of low-grade matcha tea [2].
  • Our guide to the Differences between Matcha Grades can help explain this further, here we’ll discuss how these details play into daily serving size.

Sure to be careful of low-grade matcha for daily drinking, it’s recommended to choose a source of premium matcha which is rich in the health boosting compounds.

Rest assured, any matcha is good for health. But it’s interesting how researchers identified a minimum of 2g (2 servings) each day for certain health benefits, e.g. antioxidant activity [3].

Following the standard serving size of one gram (1g) of matcha tea powder, your desired health benefits may become most pronounced between 2–4 servings per day.

If you’re interested in the cognitive performance benefits of matcha, or the potential protections against neurodegeneration, take note of recent research stating that of 4 servings (4g) of matcha in one day.

  • It was found that this dose improved speed of attention and memory functions in the human test group, as compared to controls [4].

How Much matcha Powder per Cup

If you’re wondering how much matcha powder a day that is, that’s 2 servings each 2g, or 4 servings each 1g. Since matcha tea is reported safe to consume as much as you prefer, you can decide how strong to make each cup, and how many total servings to enjoy each day.

The Bottom Line – What Results from Drinking Matcha Everyday?

Matcha green tea is an excellent tool to help put health back in your hands, or to empower your best life possible. Drinking matcha everyday results in a noticeable mood boost, optimized all-day energy, and potential benefits like weight loss, heart health, and balancing of metabolism, even anticancer research.

No matter which interests you most, or if you want to benefit from each of those possibilities, by choosing an excellent grade of matcha you’re setting yourself up for success.

And if you prefer to sip throughout the day to achieve maximum health properties, remember that unlike coffee, matcha is less likely to interfere with your sleep.

With that said, the morning and mid-afternoon are widely considered the best time to drink matcha. More importantly, be sure to pick the quality which speaks best to your health interests, or simply to fuel that hustle each day. 

Our most common recommendation is 2–3 servings per day for the average person.
