Does mate have too much caffeine? A balanced look at yerba mate's energy boost

October 9, 2025 •

4 min read

While a standard 8-ounce cup of brewed yerba mate typically contains around 80mg of caffeine, slightly less than an average cup of coffee, the effects are often described as a smoother, more sustained energy boost. This unique stimulant profile is what draws many people to this traditional South American brew.

Quick Summary

Yerba mate's caffeine content is generally moderate, though it varies by brewing method. Unlike coffee's quick jolt, mate provides a balanced energy lift due to additional compounds like theobromine and theophylline. Responsible consumption is key to enjoying its benefits while avoiding potential side effects.

Key Points

Moderate Caffeine Content: Yerba mate contains less caffeine per serving than coffee, though more than most teas.
Smoother Energy Boost: The combination of caffeine, theobromine, and theophylline provides a balanced and sustained lift without the jitters or crash.
Brewing Method Matters: Caffeine levels vary significantly based on preparation, with traditional gourds extracting more over time than quick-steeped tea bags.
Risks of Overconsumption: Excessive intake, particularly when drinking scalding hot, can lead to side effects like anxiety, insomnia, or stomach issues.
Listen to Your Body: Individual caffeine sensitivity dictates how much is too much; starting with a moderate intake is key.
Consider the Source: Pre-packaged cans can have highly concentrated caffeine, so checking labels is important for monitoring intake.

Yerba Mate vs. Coffee: The Caffeine Showdown

When comparing caffeine content, yerba mate doesn't quite measure up to coffee's high-octane reputation on a per-cup basis, but the experience is distinctly different. A typical 8-ounce cup of coffee can contain anywhere from 95 to over 200mg of caffeine, depending on the brew. In contrast, an average serving of yerba mate usually provides around 80mg of caffeine. However, the story is more complex than a simple milligram count, with the method of preparation playing a crucial role.

The Impact of Brewing Method and Quantity

The way yerba mate is prepared has a dramatic effect on its final caffeine level. For instance, a quick-steeped tea bag will yield a much lower dose than the traditional South American method using a gourd and bombilla.

Here’s a breakdown of how preparation can change the amount of caffeine you consume:

Tea Bags: A single yerba mate tea bag brewed for a few minutes might contain around 20-40mg of caffeine, similar to a cup of green tea.
French Press: Using a tablespoon of loose-leaf yerba mate in a French press can produce 50-60mg of caffeine.
Traditional Gourd and Bombilla: A traditional serving, which involves filling a gourd with a large quantity of leaves and refilling with hot water over time, can lead to a much higher total intake. Over a full sitting, this can equate to 150-200mg of caffeine, similar to a strong cup of coffee.
Canned Drinks: Pre-packaged, ready-to-drink yerba mate can also have highly variable caffeine levels, from 80mg up to 160mg per can, so it's important to check the label.

More Than Just Caffeine: A Balanced Buzz

What sets yerba mate apart is the synergistic effect of its stimulant compounds. Alongside caffeine, it contains theobromine (found in chocolate) and theophylline (found in tea). These compounds work together to produce a different kind of energy: a calm, focused alertness rather than the sharp, sometimes jittery spike associated with coffee. This means many people can enjoy the energizing benefits of yerba mate without experiencing the anxiety or crash that often follows a strong coffee. The blend of stimulants contributes to a more balanced and sustained energy release throughout the day.

Potential Side Effects and Overconsumption Risks

Like any caffeinated substance, consuming too much yerba mate can lead to adverse effects, especially for those sensitive to stimulants. Common side effects include:

Anxiety and jitters
Insomnia and sleep disturbances
Upset stomach or nausea
Increased heart rate or palpitations

In addition to the standard caffeine-related issues, there are unique risks to consider with yerba mate, specifically concerning how it is traditionally consumed. Studies have suggested a potential link between long-term, high-volume consumption of scalding hot yerba mate and an increased risk of certain cancers, such as oral, esophageal, and lung. This risk appears to be more related to the thermal damage from the high temperature of the liquid rather than the mate itself and is further amplified when combined with smoking or alcohol consumption. For most moderate drinkers consuming the beverage at a warm, not scalding, temperature, this risk is considered low.

Who Should Exercise Caution?

Certain individuals should be particularly mindful of their yerba mate consumption:

Pregnant or Breastfeeding Women: High caffeine intake can pose risks during pregnancy and pass through breast milk.
Individuals with Anxiety Disorders: The stimulant effects can exacerbate anxiety and nervousness.
People with Heart Conditions: Caffeine can cause irregular heartbeats in some people, so moderation is advised.
Those with IBS: Caffeine can trigger diarrhea and worsen symptoms.

Finding the Right Balance

For most healthy adults, a daily caffeine intake of up to 400mg is not generally associated with negative effects, according to the U.S. Food and Drug Administration (FDA). A moderate consumption of yerba mate, roughly 1-2 cups per day, is a safe and healthy way to enjoy its benefits. However, the best approach is to listen to your body and adjust your intake based on your personal tolerance.

If you're new to yerba mate or have a low caffeine tolerance, start with smaller servings to see how your body reacts before increasing your intake. Choosing a method like a French press or tea bags can provide a gentler, more controlled dose of caffeine. By being mindful of your total daily caffeine consumption and considering your brewing method, you can responsibly enjoy the clean, sustained energy that yerba mate offers.

Yerba Mate vs. Other Beverages: A Comparative Table


Beverage	Average Caffeine (mg per 8 oz)	Key Features	Potential Downsides
Yerba Mate	80	Contains theobromine and theophylline for a smooth, sustained boost; rich in antioxidants.	Potential side effects from overconsumption; risks from drinking at scalding temperatures.
Coffee (Drip)	95	Strong, quick energy spike; well-studied health benefits, but more acidic.	Can cause jitters, crash, and stomach irritation due to higher acidity.
Black Tea	40-70	Moderate caffeine content; still a good option for a gentle boost.	Higher caffeine than green or white tea; can still cause mild jitters.
Green Tea	20-45	Low caffeine content, rich in antioxidants, provides a milder energy lift.	Less potent energy boost; lower caffeine may not be enough for some.

Conclusion

The question of whether mate has too much caffeine ultimately depends on the individual and how it is consumed. While the caffeine content is comparable to or less than coffee per typical serving, the combined effect of its natural compounds offers a more balanced and sustained energy release, making it an excellent alternative for those who experience negative side effects from coffee. By understanding your own caffeine sensitivity and controlling your brewing method and quantity, you can enjoy yerba mate safely and effectively. Pay attention to how your body responds and avoid drinking it at excessively hot temperatures to mitigate potential risks.

Yes, excessive consumption of any caffeinated beverage, including yerba mate, can cause anxiety, nervousness, or jitters, especially in individuals with caffeine sensitivity or anxiety disorders.

Some research has linked long-term, high-volume consumption of scalding hot yerba mate to an increased risk of certain cancers. However, the risk is thought to be primarily due to the high temperature of the liquid, not the mate itself, and is lower for those who drink it warm and in moderation.

You can control caffeine levels by adjusting the brewing method and steeping time. Using less loose-leaf mate, opting for tea bags, or steeping for a shorter duration can reduce the final caffeine content.

For most healthy adults, a moderate intake of about 1-2 cups per day is considered safe, especially when brewed at a non-scalding temperature. Always listen to your body's signals and stay within a total daily caffeine intake of around 400mg from all sources.

Due to its high caffeine content, pregnant and breastfeeding women should consult a healthcare provider before consuming yerba mate. High doses of caffeine have been linked to complications like low birth weight and premature delivery.
