Fermented tea with kratom has sparked curiosity among those exploring natural remedies and herbal supplements. Both fermented teas, like kombucha, and kratom, a plant native to Southeast Asia, have gained popularity for their potential effects on energy, mood, and well-being. But combining these two raises questions about safety, interactions, and how they might affect the body. This blog dives into the nuances of mixing fermented teas, such as kombucha, with kratom, offering a clear and balanced perspective for those considering this combination.
What Are Fermented Teas?
Fermented teas are beverages created through a microbial fermentation process, where bacteria and yeast transform the tea’s components, often enhancing its flavour and purported health benefits. The most well-known example is kombucha, a tangy drink made from sweetened tea fermented with a symbiotic culture of bacteria and yeast (SCOBY). Other fermented teas include jun, a honey-based variation, and certain herbal infusions that undergo similar processes.
The fermentation process produces compounds like organic acids, probiotics, and small amounts of alcohol (typically less than 0.5% in commercial kombucha). These teas are often praised for supporting gut health, boosting energy, and providing antioxidants. However, their bioactive compounds can interact with other substances, including herbs like kratom, which makes understanding their composition critical.
Understanding Kratom
Kratom, derived from the leaves of the Mitragyna speciosa tree, is a botanical used for centuries in Southeast Asia. Traditionally, workers chewed the leaves or brewed them into tea for their stimulant effects at low doses and sedative effects at higher doses. The plant contains alkaloids, primarily mitragynine and 7-hydroxymitragynine, which interact with opioid receptors in the brain, producing effects ranging from increased alertness to relaxation or pain relief, depending on the dose.
In Western countries, kratom is often consumed as a powder, capsule, or tea, with users seeking benefits like pain management, mood enhancement, or relief from opioid withdrawal symptoms. However, its legal status varies, and regulatory bodies like the FDA have raised concerns about its safety, citing risks such as dependency, liver toxicity, and interactions with other substances.
Why Combine Fermented Tea with Kratom?
The idea of combining fermented tea with kratom often stems from their shared consumption as beverages. Kratom tea, made by steeping kratom leaves or powder in hot water, is a common preparation method. Some users wonder if mixing kratom with a fermented tea like kombucha could enhance flavour, improve digestion, or amplify effects. For example, kombucha’s tangy taste might mask kratom’s bitterness, making it more palatable. Others may hope the probiotics in fermented teas could aid digestion, as kratom can sometimes cause stomach discomfort.
However, combining these substances isn’t just about taste or convenience. Their active components could interact in ways that affect their potency, safety, or how the body processes them. Let’s explore the potential benefits and risks of this combination, starting with what might make it appealing.

Potential Benefits of Combining Fermented Tea with Kratom
While there’s no direct research on mixing fermented tea with kratom, we can consider their individual effects to hypothesize potential benefits. Kombucha’s probiotics may support gut health, which could be helpful for kratom users who experience nausea or constipation, common side effects at higher doses. The mild caffeine content in fermented teas (from the tea base) might complement kratom’s stimulant effects at low doses, potentially enhancing alertness or focus.
Additionally, fermented teas contain antioxidants, which could theoretically counteract oxidative stress in the body. Some kratom users report feeling fatigued after prolonged use, and the energy-boosting properties of kombucha might offer a mild counterbalance. The hydration from drinking tea could also help mitigate dehydration, a side effect sometimes linked to kratom use.
However, these potential benefits are speculative and depend on individual responses, dosages, and the specific products used. Without studies, we must weigh these against the risks, which are more substantial and better documented.
Three Key Risks of Mixing Fermented Tea with Kratom
Combining fermented tea with kratom introduces several risks, primarily due to their bioactive compounds and how they interact with the body. Below, we outline three critical concerns to consider.
1. Potential for Increased Side Effects
Kratom’s effects vary by dose, with low doses (1-5 grams) acting as a stimulant and higher doses (5-15 grams) producing sedative, opioid-like effects. Fermented teas, while generally milder, contain compounds like caffeine, organic acids, and trace alcohol, which could amplify or alter kratom’s effects. For example, the caffeine in kombucha might intensify kratom’s stimulant properties, leading to jitteriness, increased heart rate, or anxiety in sensitive individuals.
More concerning is the potential for gastrointestinal upset. Kratom can cause nausea, constipation, or stomach irritation, particularly at higher doses. Kombucha’s acidity and carbonation might exacerbate these issues, leading to discomfort or digestive distress. For individuals with sensitive stomachs, this combination could be particularly problematic.
2. Risk of Interactions with Other Substances
Both fermented teas and kratom can interact with other substances, including medications or alcohol, increasing the risk of adverse effects. Kratom’s alkaloids are metabolized by the liver, and some compounds in fermented teas, like caffeine or organic acids, could influence liver enzyme activity. This might alter how quickly or slowly kratom is processed, potentially leading to stronger or prolonged effects.
For example, combining kratom with a fermented tea containing trace alcohol (common in home-brewed kombucha) could enhance sedative effects, especially at higher kratom doses. This combination might increase the risk of drowsiness, respiratory depression, or confusion, particularly if other central nervous system depressants, like alcohol or benzodiazepines, are involved. Users taking medications metabolized by the liver, such as certain antidepressants or antipsychotics, should be especially cautious, as kratom may affect how these drugs are processed.
3. Lack of Regulation and Product Variability
Neither kratom nor fermented teas like kombucha are tightly regulated in many countries, including Canada. This lack of oversight means product quality, potency, and purity can vary widely. Kratom products may contain contaminants like heavy metals or bacteria, especially if sourced from unreliable vendors. Similarly, kombucha can harbor harmful microbes if not properly fermented or stored, particularly in home-brewed versions.
When combining these two, the risk of consuming a contaminated or inconsistent product increases. For instance, a kratom tea mixed with kombucha might mask signs of spoilage, making it harder to detect an unsafe product. Additionally, the alkaloid content in kratom can vary between strains and batches, and kombucha’s caffeine or alcohol content can differ, making it difficult to predict the combined effect.
Practical Considerations for Safe Use
If you’re considering combining fermented tea with kratom, several precautions can help minimize risks. First, start with small amounts of each. For kratom, begin with a low dose (1-2 grams) to assess your tolerance, especially if you’re new to it. Similarly, choose a commercial kombucha with consistent quality and low alcohol content to avoid unexpected interactions.
Second, pay attention to timing. Drinking kombucha and kratom tea simultaneously might increase the likelihood of stomach upset. Consider consuming them separately, with a gap of at least an hour, to monitor how each affects you. This approach also helps you identify which substance might be causing any adverse effects.
Third, choose high-quality products from reputable sources. Look for kratom vendors that provide lab testing results for contaminants and alkaloid content. For kombucha, opt for commercially produced brands that adhere to food safety standards. Avoid home-brewed kombucha unless you’re confident in its preparation, as improper fermentation can lead to contamination.
Finally, consult a healthcare professional, especially if you have pre-existing conditions like liver disease, heart issues, or mental health disorders. Kratom’s potential to interact with medications or exacerbate certain conditions makes medical guidance crucial.

How Fermented Tea with Kratom Affects the Body
To understand the safety of combining fermented tea with kratom, it’s helpful to consider how each affects the body. Kratom’s alkaloids primarily target opioid receptors, influencing mood, pain perception, and energy levels. At low doses, it stimulates the release of dopamine and serotonin, creating a sense of alertness and sociability. At higher doses, it activates mu-opioid receptors, leading to sedation and euphoria.
Fermented teas, on the other hand, affect the body through their probiotics, caffeine, and organic acids. Probiotics may support gut microbiota, potentially aiding digestion, while caffeine provides a mild stimulant effect. Organic acids, like acetic acid in kombucha, contribute to its tangy flavour and may influence gut pH, which could affect how kratom is absorbed.
When combined, these substances might interact in unpredictable ways. For example, kombucha’s acidity could alter the stomach’s pH, potentially affecting kratom’s absorption rate. This might lead to faster or slower onset of effects, depending on individual physiology. Additionally, the combined stimulant effects of low-dose kratom and kombucha’s caffeine could overstimulate the nervous system, leading to symptoms like rapid heartbeat or anxiety.
Who Should Avoid This Combination?
Certain individuals should exercise extra caution or avoid combining fermented tea with kratom altogether. These include:
- Pregnant or breastfeeding individuals: Kratom use during pregnancy has been linked to withdrawal symptoms in newborns, and the safety of kombucha’s trace alcohol or caffeine content is unclear for this group.
- People with liver conditions: Kratom has been associated with rare cases of liver toxicity, and kombucha’s organic acids might stress the liver further in susceptible individuals.
- Those with mental health disorders: Kratom can exacerbate anxiety or mood disorders in some users, and kombucha’s caffeine could amplify these effects.
- Individuals taking medications: Kratom’s potential to interact with drugs metabolized by the liver makes it risky to combine with fermented teas, which may also affect liver enzymes.
Alternatives to Combining Fermented Tea with Kratom
If the risks of mixing fermented tea with kratom outweigh the potential benefits for you, consider alternatives that achieve similar goals. For a stimulating effect, plain green or black tea can provide a caffeine boost without the complexities of fermentation. For gut health, probiotic supplements or yogurt offer a controlled dose of beneficial bacteria without the variability of kombucha.
For those using kratom for pain relief or relaxation, other herbal teas like chamomile or valerian root might provide calming effects without the risks associated with kratom’s opioid-like properties. Always research the safety and interactions of any new herbal supplement before use.
Cultural Context and Traditional Use
