- Lab figures per 4 g: Traditional ~66 mg, Green ~59 mg, Golden ~52 mg of caffeine.
- Our products range from ~22 mg (Green tea bag) to ~120 mg (1 tsp of powder).
- A 12 oz cup of brewed coffee has about 113–247 mg; black tea about 71 mg; green tea about 37 mg (FDA).
- Guayusa pairs caffeine with other natural compounds, such as theobromine and chlorogenic acids.
"Does guayusa have caffeine?" Yes, it does, and more than most people expect from a leaf that tastes this smooth. But "how much" is where most websites get vague. They'll quote a range copied from somewhere else, with no serving size and no source.
We'd rather show you our numbers. At PACHA we've had our guayusa analyzed in the lab, and we list caffeine on every product. This guide breaks down guayusa caffeine content by variety and by format, compares it with coffee and tea, and explains why so many people describe guayusa's lift as smoother.

Guayusa caffeine content: the short answer
Based on our laboratory analysis of a 4 g serving of leaf:
- Traditional guayusa: ~66 mg of caffeine
- Green guayusa: ~59 mg of caffeine
- Golden guayusa: ~52 mg of caffeine
Like any natural leaf, guayusa varies from harvest to harvest, so treat these as approximate figures, not exact doses.
So a typical cup of guayusa sits between a cup of tea and a cup of coffee. The FDA puts a 12 oz cup of brewed coffee at about 113–247 mg (roughly 75–165 mg per 8 oz), black tea at about 71 mg and green tea at about 37 mg per 12 oz.
Why the three varieties have different caffeine levels
Traditional, Golden and Green guayusa are the same leaf from the same Amazonian trees. What changes is the processing, specifically how long the leaves are allowed to wither before they're dried.
| Variety | Caffeine per 4 g | Flavor | Best for | Process |
|---|---|---|---|---|
| Traditional | ~66 mg | Rich & bold | Focus & productivity | Withered + dried |
| Green | ~59 mg | Fresh & light | Daily wellness | Withered + dried |
| Golden | ~52 mg | Smooth & mellow | Balance & well-being | Dried, no withering |
Traditional is the boldest cup and the highest in caffeine. Golden skips the withering step and is the mellowest. Green sits in between, with a lighter, fresher taste. All three are air-dried and oven-dried, and never smoked.
How much caffeine is in the leaf itself?
Online, you may read that guayusa leaves hold up to 7 or 8% caffeine, enough to make it "the most caffeinated plant on Earth." Recent lab work paints a more measured picture. Modern analyses of dried guayusa leaves generally land between about 1.5% and 3.2% caffeine by weight; one 2023 study, for example, measured 2.27%.
That places guayusa in the same range as the tea plant. A 2021 scientific review of matcha reports roughly 1.1–2.5% caffeine in green tea leaves and 1.9–4.4% in matcha.
Why do studies disagree? Leaf age, growing conditions, drying and the lab method all shift the number. It's the same reason we always give our own figures as approximate: every harvest is a little different.
What really decides the caffeine in your mug is how many grams of leaf you use, how long you steep it and whether you drink an infusion or the whole leaf (as with powder or matcha).
Caffeine per serving, by product
Lab figures per 4 g are useful for comparing varieties, but in real life you brew a tea bag or a scoop, not "4 grams." Here's the caffeine per serving as listed on each product page:
| Product | Serving | Caffeine per serving |
|---|---|---|
| Guayusa Tea Bags, 100 ct | 1 bag (2.5 g leaf) | ~41 mg |
| Guayusa Tea Bags, 50 ct | 1 bag (5 g leaf) | ~82 mg |
| Green Guayusa Tea Bags, 100 ct | 1 bag (1.5 g leaf) | ~22 mg |
| Guayusa Loose Leaf, 2 lb | 1 serving | ~66 mg |
| Guayusa Extra Fine, 2 lb | 2 tsp (about 8 g) | ~115 mg |
| Instant Guayusa Pure | 1 g (¼ tsp) | ~60 mg |
| Guayusa Powder | 1 tsp (about 6 g) | ~120 mg |
| Guayusa Cacao | 1 tsp | ~80 mg |
| For comparison: brewed coffee (FDA) | 12 oz | 113–247 mg |
| For comparison: black tea / green tea (FDA) | 12 oz | ~71 mg / ~37 mg |
A few things stand out:
- The 100-count Tea Bags (~41 mg) land close to a cup of black tea, a nice everyday or afternoon cup.
- The 50-count Tea Bags (~82 mg) use twice the leaf per bag and come close to a cup of coffee, which makes them a natural swap for your morning brew.
- The Green Tea Bags (~22 mg) are the gentlest option, handy if you want flavor and a light lift later in the day.
- Extra Fine and Powder are the most concentrated formats, for people who want a strong cup.
These are averages. Your actual cup depends on how much leaf you use, water temperature and steep time. Longer steeps and more leaf make a stronger cup.
Guayusa caffeine vs coffee
Caffeine works the same way whatever plant it comes from: it blocks adenosine, a compound that builds up in the brain during the day and makes you feel sleepy. That's why a cup of guayusa, coffee or tea all make you feel more alert.
On paper, a single tea bag of guayusa usually has less caffeine than a cup of coffee, while a 5 g bag or a teaspoon of powder reaches the range of a cup of coffee. So the real difference isn't only how much caffeine. It's how it feels.
Many guayusa drinkers describe the experience as a steadier, smoother lift: alert and focused, without the sharp spike and dip they sometimes get from coffee. That's a common description, not a guarantee. Everyone responds to caffeine differently, and how you feel also depends on sleep, food and how much caffeine you're used to.
Some other practical differences:
- Flavor: guayusa is earthy, lightly floral and smooth, with no roasted bitterness.
- Brewing: no grinder or machine needed; a longer steep simply gives you a stronger cup.
- Iced and cold brew: guayusa cold-brews easily in plain water, no machine needed.

Caffeine and L-theanine: why guayusa may feel different
You may have seen "caffeine and L-theanine" on supplement labels. L-theanine is an amino acid best known from tea (Camellia sinensis), and the pairing is popular with people looking for focus without feeling wired. In one study, a mix of about 97 mg of L-theanine and 40 mg of caffeine improved attention and alertness in young adults compared with a placebo.
A 2019 review of natural caffeine sources, including guayusa, mate, tea, coffee and cocoa, went a step further: companion compounds such as polyphenols, theobromine and L-theanine appear to shape how caffeine affects mood and focus, and may soften some of its downsides. The authors are clear that more research is needed.
Guayusa is commonly described as containing L-theanine alongside its caffeine, the same pairing tea drinkers know well. Most published research on guayusa has focused on its caffeine and polyphenols; its amino acids have been studied far less. Alongside caffeine, guayusa is also well documented to contain caffeine, a little theobromine (the compound also found in cacao), chlorogenic acids and other polyphenols. Research on guayusa in people is still limited. The best-known trial, from the University of Iowa (2024), used a concentrated extract rather than tea: a 600 mg dose raised self-reported energy compared with a placebo, and also nudged blood pressure up by 4–5 mmHg, which is typical for caffeine. So we don't make promises about what these compounds do. What we can say is that the smooth, focused feeling many drinkers describe is one of the main reasons people switch.
Caffeine without jitters: practical tips
Whether you drink guayusa, coffee or tea, a few habits help many people enjoy caffeine more comfortably:
- Start small. Try a 2.5 g tea bag (~41 mg) before moving to a 5 g bag or powder.
- Have it with food, rather than on an empty stomach.
- Sip, don't chug. A slow cup tends to feel gentler than a quick shot.
- Mind the clock. Keep stronger servings to the morning and early afternoon.
- Add it up. Count all your sources: coffee, tea, soda, energy drinks and chocolate.
Some people simply feel caffeine more than others. If you're one of them, the lower-caffeine Green Tea Bags or Golden guayusa are good places to start.
How much guayusa is too much?
The FDA notes that up to 400 mg of caffeine a day is not generally associated with negative effects in healthy adults. Using our product figures, that's a lot of guayusa, but it adds up quickly if you also drink coffee, soda or energy drinks.
During pregnancy, the American College of Obstetricians and Gynecologists (ACOG) recommends keeping caffeine under 200 mg a day. If you're pregnant or breastfeeding, take medication, have a heart condition or are sensitive to caffeine, talk to your doctor before adding guayusa to your routine. We go deeper in is guayusa safe?.

Frequently Asked Questions
How much caffeine is in guayusa tea?
In our laboratory analysis of a 4 g serving, Traditional guayusa had about 66 mg of caffeine, Green about 59 mg and Golden about 52 mg. Per product, a PACHA 2.5 g tea bag has about 41 mg and a 5 g tea bag about 82 mg. Your cup will vary with the amount of leaf, water temperature and steep time.
Does guayusa have more caffeine than coffee?
Usually not per cup, but it can. The FDA puts a 12 oz cup of brewed coffee at about 113–247 mg (roughly 75–165 mg per 8 oz). A 2.5 g guayusa tea bag has about 41 mg, while a 5 g bag has about 82 mg, close to coffee. Concentrated formats like Guayusa Powder (~120 mg per teaspoon) land well within the range of a cup of coffee.
Does guayusa have more caffeine than green tea?
Generally, yes. The FDA puts 12 oz of black tea at about 71 mg of caffeine and green tea at about 37 mg. A 4 g serving of guayusa measured between about 52 and 66 mg depending on the variety. Guayusa isn't actually a tea plant; it's a caffeinated holly related to yerba mate, which is why its profile differs.
Does guayusa contain L-theanine?
Guayusa is commonly described as containing L-theanine, the amino acid known from green tea. Most published research on guayusa has focused on its caffeine and polyphenols, and its amino acids have been studied less. What is well documented is caffeine, a little theobromine, chlorogenic acids and other polyphenols. Research on guayusa in people is still limited, so we don't make claims about its effects. Many drinkers describe guayusa as a smoother, steadier lift, though everyone responds to caffeine differently.
Will guayusa give me the jitters?
Many drinkers describe guayusa as smoother than coffee, with a steadier lift and less of a crash. That said, everyone responds to caffeine differently. If you're sensitive, start with a lower-caffeine option like Green Tea Bags (~22 mg), drink it with food, and talk to your doctor if you have concerns.
Which guayusa has the least caffeine?
Among our varieties, Golden guayusa is the mildest at about 52 mg per 4 g serving. By product, the Green Guayusa Tea Bags are the gentlest at about 22 mg per 1.5 g bag. Both are good choices for afternoons or for people who want guayusa's flavor with a lighter lift.
