Yerba mate, a traditional South American beverage, has gained worldwide recognition for its unique flavor and stimulating properties. Rich in antioxidants, vitamins, and minerals, it offers a smoother energy boost than coffee due to its blend of caffeine, theobromine, and theophylline. However, like any caffeinated drink, there are times when its consumption should be moderated or stopped entirely to prevent adverse effects.
Signs Your Body Needs a Break
Paying attention to your body’s signals is the first step in determining if you should scale back your yerba mate intake. Experiencing any of the following symptoms might indicate you're consuming too much.
Caffeine Overload Symptoms
The stimulating effects of yerba mate's caffeine content can become overwhelming for some individuals, leading to a state of overstimulation. Classic signs include:
- Jitters or shakiness: An unsteady feeling similar to having too much coffee.
- Anxiety and restlessness: Heightened feelings of nervousness, which can be particularly bothersome for those with anxiety disorders.
- Increased heart rate: An accelerated or irregular heartbeat, which is a significant concern for those with pre-existing heart conditions.
Digestive Discomfort
Yerba mate can affect the digestive system, and excessive intake may cause irritation. Symptoms of digestive distress include:
- Upset stomach or nausea
- Diarrhea, especially if you suffer from Irritable Bowel Syndrome (IBS)
Sleep Disturbances
Caffeine has a half-life of around 4-5 hours, meaning its stimulating effects can linger in your system and disrupt your sleep cycle. If you find yourself struggling to fall or stay asleep after drinking yerba mate, especially later in the day, it's a clear sign to cut back on consumption, particularly in the evening.
Health Conditions that Require Caution
Certain health situations or pre-existing conditions warrant a discussion with a healthcare provider before or during yerba mate consumption. For some, it might be necessary to stop drinking it altogether.
Pregnancy and Breastfeeding
Due to its caffeine content, yerba mate consumption should be limited during pregnancy and breastfeeding. High doses of caffeine have been linked to miscarriage, premature delivery, and low birth weight. A maximum of 200-300 mg of caffeine per day is generally recommended during pregnancy, which is roughly 2-3 traditional servings of yerba mate. Additionally, caffeine can pass into breast milk and cause irritability and increased bowel movements in infants.
Anxiety and Heart Conditions
Individuals with anxiety disorders should be cautious, as the caffeine in yerba mate can worsen symptoms. Similarly, those with heart conditions are advised to use moderation, as caffeine can cause irregular heartbeats in some individuals.
Glaucoma and Osteoporosis
Caffeine consumption can temporarily increase the pressure inside the eye, which is a concern for those with glaucoma. For individuals with weak bones (osteoporosis), caffeine can increase the amount of calcium flushed out through urine, potentially weakening bones over time.
Long-Term and High-Volume Consumption Risks
While moderate intake is generally considered safe for most adults, some studies suggest a link between long-term, high-volume consumption of yerba mate and an increased risk of certain cancers, specifically of the mouth, throat, and lungs. The risk is particularly heightened when drinking very hot mate and when combined with smoking or regular alcohol consumption. The compound polycyclic aromatic hydrocarbons (PAHs), found in some yerba mate, is the suspected carcinogen, though more research is needed.
Yerba Mate vs. Other Stimulants: When to Switch
Choosing the right beverage depends on your body's tolerance and desired effects. Here is a comparison to help you decide when yerba mate might not be the best choice for you.
| Feature | Yerba Mate | Coffee | Green Tea | 
|---|---|---|---|
| Caffeine Content (per 8oz) | ~30–85 mg | ~95–200 mg | ~20–45 mg | 
| Antioxidants | Rich source | Moderate source | Rich source | 
| Theophylline/Theobromine | Yes, promotes smoother energy | No | No | 
| Energy Effect | Sustained, balanced, fewer jitters | Rapid jolt, potential crash | Milder, gentle stimulation | 
| Best for | Sustained focus, social ritual | Quick, intense boost | Calm focus, relaxing | 
If you find yourself sensitive to yerba mate's stimulating effects, switching to green tea or a decaffeinated alternative might be a better option. The lower caffeine content and calming effects of green tea, in particular, may offer a gentler lift without the anxiety or sleep disruption.
Medication Interactions: The Need for Medical Advice
Yerba mate can interact with various medications, most notably due to its caffeine content. It is crucial to consult your doctor or pharmacist if you are taking any prescription or over-the-counter drugs.
Some potential interactions include:
- Stimulants (like amphetamines or ephedrine): Combining with yerba mate can cause excessive stimulation, increasing heart rate and blood pressure.
- Antibiotics (quinolone antibiotics): Some can reduce how quickly your body breaks down caffeine, increasing the risk of side effects.
- Medications that slow blood clotting: Caffeine might slow clotting, increasing the risk of bleeding or bruising when combined with anticoagulants.
- Cardiac stress test drugs (Adenosine, Dipyridamole): Yerba mate can block their effects, so it should be stopped at least 24 hours prior to the test.
- Benzodiazepines (sedative medications): Yerba mate can increase the breakdown of benzodiazepines, reducing their effectiveness.
When to Stop Drinking Yerba Mate: A Practical Guide
Based on your body’s signals and personal health profile, here is a quick guide on when to cease or significantly reduce your yerba mate intake:
- When you experience adverse caffeine effects, such as persistent jitters, anxiety, or insomnia.
- If you are pregnant, planning to become pregnant, or breastfeeding, due to the caffeine content.
- When you have a pre-existing health condition, like a heart condition, glaucoma, severe anxiety, or IBS, and your doctor advises against it.
- If you consume high volumes (over 1-2 liters) daily for an extended period, particularly when combined with smoking or alcohol, to mitigate potential long-term risks.
- If you take medications that interact with caffeine, as directed by a healthcare professional.
- Before a scheduled medical procedure, such as a cardiac stress test, that may be affected by caffeine.
Conclusion
Yerba mate can be a healthy and energizing beverage, but it is not without its caveats. The answer to when should I stop drinking yerba mate? is highly individual and depends on your body's tolerance, health status, and life stage. By understanding the potential side effects and health considerations, you can consume it responsibly and know when to listen to your body's cues to reduce or stop intake. Always prioritize moderation and consult a healthcare professional with any concerns, especially regarding chronic consumption or existing medical conditions.
