Cons of matcha include potential caffeine side effects (anxiety, insomnia), digestive upset, liver concerns with excessive intake, risk of heavy metal/pesticide contamination in low-quality brands, high cost, and interference with iron absorption, especially for those with anemia, making moderation and quality sourcing crucial.
Key Takeaways
Drinking too much matcha can cause GI upset in some people, particularly due to its caffeine and tannin content. One study notes that higher caffeine intake can exacerbate stomach discomfort, especially in people with reflux or IBS. One cup a day is generally considered safe and beneficial.
Gen Z's obsession with matcha stems from its aesthetic appeal on social media, perceived health benefits (antioxidants, calm energy), and its role in "little treat culture," offering a customizable, mindful indulgence that contrasts with coffee's jitters. Its vibrant green color makes it highly "Instagrammable," fueling viral trends and linking it to self-care, wellness, and "main character energy" for a generation seeking meaningful, shareable experiences, say BeverageDaily.com and Global Coffee Report.
Even though matcha has less caffeine than coffee, it can still trigger insomnia, anxiety or jitters in sensitive individuals. Moderate consumption is generally considered safe, but excessive caffeine may increase risks during pregnancy or affect the baby during breastfeeding.
Matcha is often considered healthier than coffee due to its unique combination of caffeine and L-theanine, which provides sustained, calm focus without the jitters, plus a higher antioxidant load from consuming the whole leaf, including beneficial catechins like EGCG; however, coffee has more caffeine and its own heart health benefits, so the "healthier" choice depends on individual preference for energy style and specific health goals. Matcha offers potent antioxidants and supports focus, while coffee provides a stronger, quicker energy boost, making matcha great for calm alertness and coffee better for immediate energy.
However, it's important to remember that matcha still contains caffeine—typically around 30-70 mg per serving. For those who are sensitive to caffeine, even this moderate amount can sometimes cause side effects like jitters, nausea, or digestive discomfort.
“The beneficial compounds it contains, such as catechins, may be harmful in high quantities. It's best to consume matcha in moderation, for instance, 1–2 cups of tea per day or up to 2 teaspoons of matcha.”
Matcha decreases stress and anxiety, improves memory and short- and long-term cognitive function in humans, while having no effect on mood.

The "30 20 10 matcha" method is a whisking technique to create smooth, velvety microfoam for your matcha latte, involving 30 seconds of vigorous W/M-shaped whisking to build froth, 20 seconds of slower whisking to refine bubbles, and 10 seconds of gentle surface skimming to pop large bubbles and achieve a silky finish, ensuring lump-free, perfectly textured matcha.
The cons of matcha include its high cost, potential for caffeine sensitivity (jitters, anxiety, sleep issues), risk of heavy metal/pesticide contamination (especially with low-quality brands), and possible interference with iron absorption, plus potential liver stress or thyroid issues in very high doses, all due to consuming the whole leaf. It also requires careful storage to maintain nutrients and can cause stomach upset if too much is consumed.
