Welcome to the world of matcha tea! Today, we're exploring an exciting question: can Matcha make you sick? 

While Matcha is renowned for its health benefits, there have been concerns about potential side effects. Some individuals have reported feeling nauseous or experiencing an upset stomach after consuming Matcha. 

In this article, we'll dive into the topic and examine the evidence to comprehensively understand whether Matcha can make you sick. So, grab a cup of your favorite tea and join us as we uncover the potential effects of Matcha on our well-being. 

What is Matcha?

First, let's define what exactly Matcha is. Matcha is a green tea that has been finely ground into a powder. It originated in Japan and has been used in traditional tea ceremonies for centuries. Unlike regular green tea, where the leaves are steeped and then discarded, matcha powder is dissolved directly into the water, allowing for a higher concentration of nutrients to be consumed. 

Matcha green tea powder is made from shade-grown green tea leaves, which increases the amount of chlorophyll and amino acids in the leaves. This results in a vibrant green color and a unique flavor profile that sets Matcha apart from other types of tea. While drinking Matcha tea is the most common way to consume it, matcha powder can also be used in smoothies, baked goods, and even face masks. 

Health Benefits of Matcha

Matcha has gained popularity in recent years due to its numerous health benefits. It's packed with antioxidants, vitamins, and minerals that can contribute to overall health and well-being. Some potential benefits of Matcha include: 

  • Boosted energy levels
  • Improved cognitive function
  • Enhanced metabolism
  • Lowered risk of chronic diseases 

Can Matcha Make You Sick? 

The short answer is yes, but it's not as simple as it sounds. While Matcha itself is not toxic, consuming too much of it can lead to unpleasant side effects. Matcha contains caffeine, which can cause nausea or an upset stomach in some individuals, especially if consumed on an empty stomach. The recommended amount of Matcha per day is 1-2 cups, which should be enough to reap the potential benefits without experiencing any adverse effects. 

High quality Matcha powder is also free of any harmful additives or contaminants. However, lower-quality Matcha may contain lead, which can be toxic in large amounts. It's essential to purchase Matcha from a reputable source and to avoid consuming excessive amounts to minimize the risk of lead poisoning. 

If you drink properly watered Matcha and stick to the recommended amount, it shouldn't make you sick. However, if you experience discomfort after drinking Matcha, it's best to consult your healthcare provider. 

Causes Of Matcha Nausea And How To Prevent It 

Aside from caffeine sensitivity, there are a few other reasons why you may experience nausea or stomach discomfort after drinking Matcha: 

Having Matcha On An Empty Stomach: 

As mentioned earlier, Matcha contains caffeine and can irritate an empty stomach. Consuming Matcha with food is recommended to avoid any potential nausea or upset stomach. 

What To Do: 

If you experience nausea after drinking Matcha on an empty stomach, try having it with a meal or snack next time. Additionally, consider switching to decaffeinated Matcha to see if that helps alleviate any discomfort. 

Adding Sweeteners To Matcha: 

While adding sugar or honey to your Matcha may be tempting, it can contribute to nausea and stomach discomfort. The added sugar can disrupt the balance of bacteria in your gut, leading to digestive issues. 

What To Do: 

Try drinking Matcha without any sweeteners and see if that makes a difference. If you prefer a sweeter taste, consider using natural sweeteners like stevia or monk fruit. 

Adding Dairy To Matcha: 

Some individuals may experience nausea or stomach upset when consuming Matcha with dairy products. This could be due to lactose intolerance or a sensitivity to casein, a protein found in milk. Blending matcha with dairy may also affect the absorption of antioxidants in the tea. 

What To Do: 

If you think dairy may be the culprit behind your matcha-related discomfort, try substituting dairy milk with a non-dairy alternative like almond or coconut milk. You can also try using Matcha in recipes that don't call for dairy, such as a matcha smoothie with almond milk or a matcha latte made with oat milk. 

Caffeine In Matcha

As mentioned earlier, caffeine is a component of Matcha that can cause some individuals to feel sick. If you're sensitive to caffeine or have consumed other sources of caffeine before having Matcha, the combination may lead to nausea or an upset stomach.  Too much Matcha can also cause caffeine crash, which can lead to fatigue and brain fog. 

What To Do: 

Pay attention to your caffeine intake and try to limit it to 400mg daily, the recommended daily intake. This includes all sources of caffeine, not just Matcha. If you still experience discomfort after restrict your caffeine intake, consider trying decaffeinated Matcha or switching to a different type of tea altogether. 

Drinking Other Caffeinated Beverages With Matcha:

In addition to being mindful of your overall caffeine intake, it's also essential to avoid consuming other caffeinated beverages with Matcha. This includes coffee, black tea, and energy drinks. Combining different sources of caffeine can increase the risk of side effects such as nausea or jitteriness. 

What To Do: 

Stick to one source of caffeine at a time and limit your overall intake, as mentioned earlier. If you're used to having coffee in the morning and Matcha in the afternoon, consider switching one of those drinks for a caffeine-free alternative, like herbal tea or decaffeinated coffee. 

These are just a few common causes of matcha-related nausea and potential solutions to try. It's essential to listen to your body and make adjustments as needed, but consuming Matcha in moderation should not make you sick. 

Common Side Effects Of Matcha 

Aside from nausea and stomach discomfort, there are a few other potential side effects of Matcha that you should be aware of: 

  • Headaches or migraines: Caffeine can cause headaches in some individuals, especially if consumed in large amounts. If you experience frequent headaches after drinking Matcha, try reducing your intake to see if that makes a difference.
  • Insomnia or difficulty sleeping: As with any source of caffeine, consuming Matcha close to bedtime can make it difficult to fall asleep. If you're having trouble sleeping after drinking Matcha, try avoiding it in the evening or opting for decaffeinated versions.
  • Heartburn or acid reflux: The caffeine and tannins in Matcha have been linked to acid reflux in some individuals. If you have a history of acid reflux or heartburn, it's best to consume Matcha in moderation and with food.
  • Anxiety or jitters: Caffeine can also cause feelings of anxiety or jitteriness in some people. If this concerns you, try limiting your matcha intake or opting for decaffeinated versions.

Overall, while there are a few potential side effects of consuming Matcha, they can usually be avoided by drinking it in moderation and being mindful of other sources of caffeine.
