FAQ
Q 1. How Much Caffeine Is In Green Tea?
A :
An 8-ounce (237 ml.) cup of green tea typically contains around 35 mg of caffeine.
However, the exact caffeine content can vary depending on factors such as the type of green tea, the growing conditions of the leaves, the harvesting and processing season & methods, and the brewing technique.
As a result, the caffeine content in green tea can range from 12 to 75 mg per 8-ounce cup, with matcha green tea occasionally exceeding this range.
Q 2. How Much Caffeine Is Too Much?
A :
According to medical experts, including here at the FDA, caffeine can be part of a healthy diet for most people, but too much of it can have negative effects and large amounts may pose a danger to your health. Depending on factors such as body weight, medications you may take, certain medical conditions, and individual sensitivity, “too much” can vary from person to person. Be aware of the level of caffeine in your diet and look out for signs when it’s too much.
Daily Caffeine Consumption for Most Adults
For most adults, the FDA has cited 400 milligrams* a day — that’s about two to three 12-fluid-ounce cups of coffee — as an amount not generally associated with negative effects. However, there is wide variation in both how sensitive people are to the effects of caffeine and how fast they eliminate it from the body.
Certain conditions tend to make people more sensitive to caffeine’s effects, as can some medications. If you are concerned about a condition or medication, or if you’re pregnant, trying to become pregnant, or breastfeeding, we recommend talking to your health care provider about whether you need to limit caffeine consumption.

Q 3. Comparison Green Tea caffeine vs. Matcha vs. Black Tea vs. Coffee !
A :
Curious how the caffeine in green and black teas compares to coffee? Let’s break it down:
A typical cup of coffee or a shot of espresso packs anywhere from 100 to 200 mg of caffeine, depending on the type of bean and brewing time. In contrast, green tea delivers a more modest dose of around 35 mg per cup. If you’re looking for a bigger caffeine boost, consider matcha tea.
Matcha, a powdered form of green tea, stands out with significantly more caffeine than regular green teas. Because matcha involves consuming the entire tea leaf rather than just the brewed liquid, a cup can contain up to 80 mg of caffeine—an energizing option for tea lovers.
Black tea offers a caffeine range of 40–80 mg per cup, influenced by leaf quality and brewing methods.
Oolong tea sits comfortably between green and black teas in caffeine content, w
hile white tea takes the low-caffeine crown with just 10–20 mg per cup.
For those steering clear of caffeine, decaffeinated versions of green tea, black tea, and even coffee are readily available at most grocery stores. Herbal teas are also a caffeine-free option—though keep in mind, blends like yerba mate or guayusa do contain caffeine.

Have you ever noticed how differently your body responds to a cup of green tea versus coffee? Even when containing similar amounts of caffeine, these beloved beverages can create distinctly different experiences in our bodies.
The secret lies in green tea’s unique chemistry. While coffee delivers its caffeine in a swift, powerful rush, green tea takes a more nuanced approach. The caffeine molecules in green tea form bonds with its natural antioxidants, creating a slow-release effect that your body processes gradually. This means you’re less likely to experience the familiar coffee cycle of sudden energy spike followed by an abrupt crash.
Green tea, in particular, offers something special: L-theanine, a remarkable amino acid that works in harmony with caffeine. Think of L-theanine as caffeine’s wise companion, helping to smooth out the energizing effects while promoting a sense of calm focus. Instead of the jitters or nervous energy that coffee might bring, green tea tends to provide a balanced, sustained alertness.
For those looking to reduce their coffee intake or those who find coffee’s effects too intense, green tea offers an elegant alternative. You don’t have to give up caffeine entirely – you can simply choose a gentler path. Green tea provides the alertness you seek, wrapped in a more balanced, body-friendly package.
This natural synergy between green tea’s compounds explains why many people find they can enjoy green tea even when coffee proves too stimulating. It’s not about the quantity of caffeine – it’s about how your body experiences it.
