Can Kids Drink Green Tea?
Can kids drink green tea? Would you be surprised if I tell you even toddlers drink green tea in Japan? I have been asked, ‘Is it OK to give green tea to my teenage kids?’ That question surprised me since I’ve grown up in a culture where green tea is given even to babies, although the kind of green tea would be a diluted roasted green tea, which offers naturally less caffeine and a comforting roasted aroma.
In Japan, Kids Turn on Water Faucet to Get Green Tea
I can hear some folks who watch green tea poured down into the sink frown and say, “It’s wasting green tea!” I have to say these schools are located in Shizuoka, Japan, where green tea is produced on a big scale. And there is abundant green tea for schools to buy cheaply. Because green tea is anti-viral and anti-bacterial, kids get benefits from hand washing, mouth rinsing, and gargling with green tea.
They also serve green tea items in school lunches almost everyday. If you are interested in cooking with green tea, check out some of our our recipe pages!
Is Green Tea Safe for Kids?
The question must be associated with caffeine, which naturally exists in green tea. Caffeine in an 8oz green tea depends on how you make it, but it would be no more than 40mg if you are making green tea in a palatable proportion. Shade-grown green tea, such as high grade ceremonial matcha are covered in shade for a longer time period, would offer more - 70mg in an 8 oz tea. Yu’s ‘regular’ Sencha powder tea offers 10-16 mg of caffeine in one cup. There is about 100mg of caffeine in a normal cup of coffee. Caffeine amounts in the beverages popular among young people are: Mountain Dew 54 mg/12 oz, Coke 34m/12 oz, Dr. Pepper 41mg/12oz, Monster Energy Drink 160mg/16 oz. Hershey’s Special Dark Chocolate Bar 1.45oz has 20mg caffeine. The American Academy of Pediatrics suggests that children under the age of 12 years should not eat or drink any caffeine-containing foods or drinks. (That means no chocolate of any form for children?!) For children older than 12 years, caffeine intake should be no more than 85 to 100 milligrams per day.
Caffeine, L-theanine and EGCG in Green Tea Work Together
Why do Japanese schools offer green tea and green tea foods at schools? The key may be the other substances that exist naturally in green tea. There is a study that researched the synergetic effects of L-theanine, caffeine, and EGCG—the most prominent antioxidant found in Green Tea - 25 times more powerful than Vitamin E and 100 times more powerful than Vitamin C. This report concluded: “This study highlights the importance of the synergism between tea components for the beneficial effects usually attributed to this beverage.” Let’s review the green tea benefits students would enjoy.
Caffeine and L-theanine create “Calm Alertness”
L-theanine, a natural relaxant found almost exclusively in green tea, counteracts caffeine - it does not “cancel out” the caffeine effect. L-theanine mitigates the undesirable aspects of caffeine - jitters, tension, and agitation. L-theanine in combination with Caffeine generates “Calm Alertness”. First, you are relaxed yet alert at the same time. Second, the energy you get doesn’t give you energy hype and crash; instead, you get steady energy. Do you think active youngsters could use this benefit? Energized but not hyped - that sounds like a great way to be in a classroom.
Green Tea Can Reduce Anxiety and Increases Attention
Speaking of classroom environments, there are many studies on the relationship between green tea and cognitive abilities in humans. “Green tea effects on cognition, mood and human brain function: A systematic review” assessed the previous studies and concluded as follows: “The reviewed studies presented evidence that green tea influences psychopathological symptoms (e.g. reduction of anxiety), cognition (e.g. benefits in memory and attention) and brain function (e.g. activation of working memory seen in functional MRI).” And they reported the benefits are observed when L-theanine is combined with caffeine.
Green Tea Can Enhances Memory
Swiss researchers did an experiment with 2 groups to find out if EGCG enhances working memory using MRI (magnetic resistance imaging). The green tea drinkers performed better on memory tests than the placebo group. The MRIs revealed why: Their parietal lobes (which process sensory information into words and thoughts) and their frontal lobes (responsible for decision making and problem-solving) were better able to communicate with each other. By increasing the amount of interplay between these two brain regions, green tea boosted these people’s ability to retain information.
Kids Deserve Green Tea Goodness
With such a powerful and long list of health benefits, green tea is often associated with life-extension tactics, but green tea benefits are not only for seniors. Green tea is a great drink for teenagers and possibly pre-teenagers; if you choose the right green tea and fix it right. Of course, there are individual differences, so you may want to start slowly and use caution. If your children can drink green tea, that may be a tremendous benefit for them.
How about Matcha for children?
Matcha has two characteristics:
- Matcha uses the leaves grown in shade.
- Matcha is a finely ground tea leaf and you consume the entire leaf rather than steep it.
These two conditions make caffeine content in Matcha higher than in regular green tea. To learn more about the differences between shade-grown tea leaves and tea leaves grown in full sun, learn more about the differences between matcha and sencha.
Generally speaking, the longer the shading period, the higher the caffeine content in the tea leaf. That means ceremonial grade matcha offers more caffeine than lower grade matchas. Yet lower grade matcha still offers more caffeine than other green tea powder types, such as Sencha powder, Hojicha, and Genmaicha.

The caffeine content of Ceremonial grade matcha can be as high as 80 mg in one serving. Lower grade matcha can be in the 35-50 mg of caffeine in one serving. Based on the caffeine intake limits we explained above, the kids over 12 should limit to one serving a day, if they drink Ceremonial matcha. Kids under 12 should choose other options, such as Decaf Matcha, Sencha, Decaf Sencha, Genmaicha, or Hojicha.
