Bold fuel comes with a few cautions, here’s what you need to know.
Why People Ask About Side Effects
Yerba mate has been celebrated in South America for centuries and is gaining global recognition for its clean, sustained energy. But with popularity comes the big question: Are there any side effects of drinking yerba mate?
The truth: yerba mate is safe for most people when consumed in moderation. Like coffee or tea, it contains caffeine and other natural compounds that can cause side effects if overused.
Common Side Effects of Yerba Mate
Caffeine Sensitivity
Yerba mate contains 30–50mg of caffeine per 8oz cup. For those sensitive to caffeine, this can cause:
Restlessness
Insomnia (if consumed late in the day)
Rapid heartbeat or jitters
Stomach Upset
Some people may experience mild digestive discomfort when drinking mate on an empty stomach, especially if it’s brewed strong.
Increased Bathroom Trips
Yerba mate acts as a mild diuretic, so expect more frequent urination—similar to coffee or tea.
Interaction with Medications
Because it contains caffeine, mate can interact with medications for blood pressure, heart conditions, or anxiety. Always consult a doctor if you’re on medication.
The Hot Drink Controversy
One of the most talked-about concerns around yerba mate is its potential link to cancer. Research suggests this is not about the plant itself, but about how hot it’s consumed.
Regularly drinking very hot beverages (above 149°F / 65°C) has been linked to a higher risk of esophageal cancer.
This risk applies to any hot beverage, including coffee and tea, not just yerba mate.
The solution: brew at 160–175°F and allow it to cool slightly before sipping. You still get the flavor and energy without the scalding heat.
Who Should Limit Yerba Mate?
Pregnant or breastfeeding individuals → Limit caffeine and consult a healthcare provider.
People with caffeine sensitivity → Start with small servings and monitor how you feel.
Those with certain medical conditions → Always check with a doctor before making mate a daily habit.
How to Avoid Side Effects
Moderation is key: 2–3 servings a day is safe for most people.
Mind the clock: Avoid drinking late at night to prevent insomnia.
Brew at the right temperature: Stick to 160–175°F to avoid risks from very hot liquids.
Experiment with blends: Add mint or chai to smooth out the flavor and reduce harshness on the stomach.
