Kombucha headache. Kombucha Side Effects: 7 Potential Risks of Overconsumption
What are the potential side effects of drinking too much kombucha. How can excessive kombucha consumption impact your health. Is it possible to experience headaches from kombucha overconsumption. Can drinking large amounts of kombucha lead to stomach upset.
Understanding Kombucha: A Fermented Tea Beverage
Kombucha, a fermented drink derived from green or black tea, sugar, bacteria, and yeast, has gained significant popularity in recent years. This unique beverage, described in a December 2015 review published in the Journal of Chemistry, offers potential health benefits due to its fermentation process. The fermentation creates probiotics, which are live organisms that help maintain a balance between good and bad bacteria in the gut.
While kombucha is often touted for its potential to reduce inflammation, boost immunity, and increase metabolism, it’s crucial to note that human research on these benefits is limited. Dr. Alissia Zenhausern-Pfeiffer, a licensed naturopathic medical doctor in Scottsdale, Arizona, suggests that we can speculate on its benefits based on its ingredients. However, the Cleveland Clinic emphasizes the need for more comprehensive studies to confirm these potential health advantages.
The Dark Side of Kombucha: Potential Risks of Overconsumption
Despite its possible therapeutic benefits, kombucha isn’t suitable for everyone, and excessive consumption can lead to adverse effects. The Mayo Clinic warns about the risks associated with drinking too much kombucha and improper preparation. Let’s explore seven reported side effects of kombucha overconsumption:
1. Digestive Distress: When Kombucha Upsets Your Stomach
While kombucha may promote gut health and alleviate conditions like constipation and hemorrhoids, excessive intake can lead to digestive issues. Drinking large amounts of kombucha may cause nausea and diarrhea. The acidic nature of kombucha can trigger nausea in individuals sensitive to acidic beverages.
Additionally, some kombucha brands contain added sweeteners. Consuming too much sugar or sweeteners can result in diarrhea or watery stools, as indicated by a study. For those unaccustomed to probiotics, rapid introduction of large quantities can lead to similar symptoms.
2. Kombucha-Induced Headaches: A Potential Side Effect
Headaches are another possible adverse effect of drinking excessive amounts of kombucha. While the exact cause remains unknown, kombucha contains caffeine and alcohol, which individually or combined might trigger headaches in sensitive individuals.
Interestingly, caffeine is sometimes used as a headache reliever. However, past research has shown that repeated exposure to caffeine can have the opposite effect, potentially leading to chronic daily headaches.
3. Lactic Acidosis: A Rare but Serious Concern
For those consuming multiple bottles of kombucha daily, there’s a risk of developing lactic acidosis. This condition occurs when lactic acid, an organic acid produced in muscles, accumulates in the bloodstream, causing the body’s pH to become too acidic. This can potentially lead to problems with liver and kidney function and become life-threatening.
The Centers for Disease Control and Prevention (CDC) has reported two cases of illness associated with kombucha consumption and elevated levels of lactic acid. In these instances, both women consumed 4 to 12 ounces of home-brewed kombucha daily for two months. However, it’s important to note that a direct causal relationship between kombucha and lactic acidosis has not been definitively established, and more research is needed.
Symptoms of lactic acidosis include muscle aches, disorientation, nausea, headaches, fatigue, rapid heart rate, and jaundice (yellowing of the eyes or skin).
4. Lead Poisoning: A Risk from Improper Brewing
Overfermentation during the preparation process may lead to severe lead poisoning under certain brewing conditions. The risk of poisoning increases when kombucha is home-brewed in clay vessels or ceramic pots containing high levels of lead. The lead can leach or dissolve into the beverage, causing a buildup of lead in the body.
Past research has documented at least one incident of lead poisoning linked to a lead-glazed ceramic pot used for brewing kombucha. This underscores the importance of using appropriate brewing vessels and following proper fermentation guidelines.
Kombucha and Alcohol Content: A Hidden Concern
One often overlooked aspect of kombucha consumption is its alcohol content. During the fermentation process, kombucha naturally produces a small amount of alcohol. While commercial kombucha products are typically regulated to contain less than 0.5% alcohol by volume, home-brewed versions may contain higher levels.
For individuals sensitive to alcohol or those in recovery from alcohol addiction, even small amounts of alcohol in kombucha can be problematic. It’s crucial to be aware of this aspect, especially when consuming home-brewed kombucha or products from small-scale producers.
Alcohol Content Variation in Kombucha
- Commercial kombucha: Generally less than 0.5% alcohol by volume
- Home-brewed kombucha: Can range from 0.5% to 3% alcohol by volume
- Overfermented kombucha: May contain even higher alcohol levels
Can kombucha’s alcohol content affect your sobriety. For individuals in recovery or those avoiding alcohol for other reasons, it’s advisable to consult with a healthcare professional before incorporating kombucha into their diet. Some may choose to opt for non-alcoholic alternatives or carefully monitored commercial products.
The Sugar Conundrum: Balancing Health Benefits and Risks
While kombucha is often praised for its potential health benefits, it’s important to consider its sugar content. The fermentation process consumes some of the initial sugar, but the final product still contains a significant amount of sugar, especially in flavored varieties.
For individuals managing diabetes or watching their sugar intake, this can be a concern. The sugar content in kombucha can vary widely depending on the brand and brewing method.
Average Sugar Content in Kombucha
- Unflavored kombucha: 2-6 grams of sugar per 8 oz serving
- Flavored kombucha: 5-12 grams of sugar per 8 oz serving
- Some commercial brands: Up to 20 grams of sugar per 8 oz serving
How does kombucha’s sugar content compare to other beverages. While kombucha generally contains less sugar than sodas or fruit juices, it’s not a sugar-free option. For comparison, an 8 oz serving of cola typically contains about 26 grams of sugar, while the same amount of orange juice contains about 21 grams.
For those monitoring their sugar intake, it’s crucial to read labels carefully and consider kombucha as part of their overall daily sugar consumption. Some brands offer low-sugar or sugar-free options, which may be more suitable for those with dietary restrictions.
Kombucha and Pregnancy: Weighing the Risks
Pregnant women are often advised to exercise caution with kombucha consumption. The concerns primarily revolve around three factors: the potential presence of harmful bacteria, the alcohol content, and the caffeine content.
During pregnancy, the immune system is naturally suppressed, making women more susceptible to foodborne illnesses. While properly prepared kombucha is generally safe, there’s a risk of contamination, especially with home-brewed versions.
Key Considerations for Pregnant Women
- Bacterial contamination risk: Higher with home-brewed kombucha
- Alcohol content: Even small amounts may be concerning during pregnancy
- Caffeine intake: Kombucha contributes to daily caffeine consumption
- Unpasteurized nature: May pose risks similar to other unpasteurized foods
Is it safe for pregnant women to drink kombucha. The consensus among health professionals is that pregnant women should either avoid kombucha or consume it with extreme caution. If choosing to drink kombucha during pregnancy, it’s advisable to opt for commercial, pasteurized versions and to consult with a healthcare provider first.
For those who enjoy the taste and potential benefits of kombucha but want to avoid these risks during pregnancy, there are several alternatives to consider:
- Probiotic-rich yogurt or kefir
- Decaffeinated herbal teas
- Sparkling water with a splash of fruit juice
- Coconut water
Kombucha Interactions: Medications and Health Conditions
While kombucha is generally considered safe for most people, it can interact with certain medications and exacerbate some health conditions. Understanding these potential interactions is crucial for safe consumption.
Medications That May Interact with Kombucha
- Blood thinners: Kombucha’s vitamin K content may interfere with their effectiveness
- Diabetes medications: The sugar content in kombucha may affect blood sugar levels
- Antacids: Kombucha’s acidity may reduce their efficacy
- Probiotics: May lead to an overload of probiotics when combined with kombucha
Can kombucha affect the absorption of medications. In some cases, yes. The acidity of kombucha may alter the absorption rate of certain drugs. Additionally, its probiotic content could potentially influence the gut microbiome, which plays a role in drug metabolism.
Health Conditions to Consider
Individuals with certain health conditions should exercise caution or consult a healthcare provider before incorporating kombucha into their diet:
- Compromised immune systems: Higher risk of adverse reactions to probiotics
- Digestive disorders: May exacerbate symptoms in some cases
- Candida overgrowth: The sugar content might feed yeast infections
- Histamine intolerance: Fermented foods like kombucha are high in histamines
How does kombucha impact individuals with autoimmune disorders. The effects can vary. While some may benefit from the potential anti-inflammatory properties, others might experience adverse reactions due to the immune-stimulating effects of probiotics. It’s essential to introduce kombucha slowly and monitor any changes in symptoms.
Moderation and Safety: Guidelines for Kombucha Consumption
To enjoy the potential benefits of kombucha while minimizing risks, it’s important to consume it in moderation and follow safety guidelines. Here are some recommendations for safe kombucha consumption:
Recommended Daily Intake
- General recommendation: 4-8 ounces (120-240 ml) per day
- Maximum suggested intake: No more than 12 ounces (360 ml) daily
- Start with small amounts: Begin with 2-4 ounces and gradually increase
How much kombucha is too much. While individual tolerance varies, exceeding 12 ounces per day may increase the risk of side effects. It’s crucial to listen to your body and adjust consumption accordingly.
Safety Tips for Kombucha Consumption
- Choose reputable brands: Opt for commercially prepared kombucha from trusted sources
- Check labels: Look for added sugars, alcohol content, and pasteurization status
- Store properly: Keep kombucha refrigerated to prevent over-fermentation
- Be cautious with home brewing: Follow strict hygiene practices and use appropriate equipment
- Monitor for side effects: Pay attention to any digestive discomfort, headaches, or other symptoms
- Consult a healthcare provider: Especially if you have pre-existing health conditions or are pregnant
Is it safe to drink kombucha every day. For most healthy adults, daily consumption within the recommended limits is generally safe. However, it’s important to vary your diet and not rely solely on kombucha for probiotic intake or other nutritional needs.
By following these guidelines and being mindful of your individual health needs, you can enjoy kombucha as part of a balanced diet while minimizing potential risks associated with overconsumption.
What Are the Side Effects of Drinking Too Much Kombucha?
Kombucha is a fermented drink made from green or black tea, sugar, bacteria, and yeast. That description of kombucha, which comes from a review published in December 2015 in the Journal of Chemistry, may sound strange, but the beverage is gaining popularity throughout the United States — and for good reason. (1)
The fermented process of brewing kombucha makes it a potential source of probiotics, which are live organisms that help balance good and bad bacteria in the gut. Proposed benefits of kombucha include its potential to reduce inflammation, boost immunity, and increase metabolism, according to the aforementioned review. (1)
It’s important to note that there is not a wealth of human research on the potential health benefits of kombucha, as the Cleveland Clinic points out. (2) Nonetheless, it’s possible to speculate on its benefits given what the drink is made of, says Alissia Zenhausern-Pfeiffer, MD, a licensed naturopathic medical doctor practicing in Scottsdale, Arizona.
7 Potential Health Dangers of Too Much Kombucha
There’s no short list of potential health benefits of kombucha. Some people also believe that it can help detoxify the body, reduce blood sugar, and inhibit the growth of cancer cells, according to the Cleveland Clinic. (2)
But despite possible therapeutic benefits, kombucha isn’t right for everyone, and there’s the risk of adverse effects from drinking too much and improper preparation, notes the Mayo Clinic. (3)
Here’s a look at seven reported side effects of too much kombucha:
1. Drinking Too Much Kombucha May Upset Your Stomach
Even though kombucha might promote gut health and improve conditions like constipation and hemorrhoids, too much of any good thing can be bad, according to one review. (1)
For that matter, drinking a large amount of kombucha may cause nausea and diarrhea. (1,2)
Kombucha is acidic, so it’s possible for the drink to trigger nausea in those who are sensitive to acidic drinks. (1)
Also keep in mind that some brands of kombucha may have sweeteners added to them. Eating too much sugar and too many sweeteners can lead to diarrhea or watery stools, according to a study. If your body isn’t used to probiotics, consuming too many too quickly can lead to similar symptoms. (4)

2. Overdoing It With Your Kombucha Habit May Lead to Headaches
Headaches are another possible adverse side effect of drinking too much kombucha. (1) The exact cause of a headache is unknown, but kombucha does contain caffeine and alcohol, which alone or together might induce headaches in those who are sensitive.
Caffeine is sometimes used as a headache reliever. But while an effective treatment, repeated exposure to caffeine can have the opposite effect, triggering chronic daily headaches, past research has noted. (5)
3. Excess Kombucha May Contribute to Lactic Acidosis
The philosophy that too much of a good thing can be bad applies to kombucha.
Though the occasional kombucha drinker needn’t worry about this side effect, those drinking multiple bottles of kombucha every day may be at risk for a condition called lactic acidosis.
Lactic acid is an organic acid produced in the muscles. (6) Swigging kombucha can cause an accumulation of this acid in the bloodstream, causing the body’s pH to become too acidic. This can lead to problems with liver and kidney function, and become life-threatening, past research has suggested. (7)
The amount of kombucha linked to lactic acidosis hasn’t been established. Yet the Centers for Disease Control and Prevention (CDC) has reported two illnesses associated with kombucha and elevated levels of lactic acid. In these cases, both women consumed 4 to 12 ounces (oz) of home-brewed kombucha daily for two months. Still, there is no proof the kombucha itself caused the lactic acidosis; the CDC simply observed a link between the two. More research is needed to determine the amount of kombucha that can cause this condition. (8)
Symptoms of lactic acidosis include muscle aches, disorientation, nausea, headaches, fatigue, rapid heart rate, and jaundice (yellowing of the eyes or skin). (9) Among the known causes of this condition are human immunodeficiency virus (HIV) drugs, which can cause lactic acidosis buildup.
4. Overfermented Kombucha Has Been Tied to Lead Poisoning
Be mindful that overfermentation during the preparation process may lead to severe lead poisoning under certain brewing conditions. (1)
The risk of poisoning is greater when kombucha is home-brewed in a clay vessel or ceramic pot containing high levels of lead. The lead can leach or dissolve into the beverage, causing a buildup of lead in the body. (2) In fact, past research showed at least one incident of lead poisoning linked to a lead-glazed earthenware jug used to store kombucha tea. (10)
Symptoms of lead poisoning include high blood pressure, headache, abdominal pain, mood disorders, difficulty concentrating, and muscle pain. (11)
Not only do some ceramic pots contain lead, but so do some china and porcelain containers. (11)
5. Drinking Kombucha Every Day May Damage Your Teeth
“Drinks that have high-acid levels, such as kombucha, can wear away your teeth, which can lead to decay, sensitivity, and discoloring,” says Jeffrey Sulitzer, DMD, the chief clinical officer at SmileDirectClub, a teledentistry company, who is based in Woodland, Washington.
Because kombucha has a high acidic level that may be harmful to your teeth and gums, Dr. Sulitzer suggests several ways to help keep your teeth healthy and safe.
“I would suggest drinking kombucha through a straw, to help reduce the direct contact the beverage has to your teeth. Directly after you finish your drink, rinse your mouth out with water to help remove the sugars and acidic components from your mouth,” he adds.
6. You’ll Take in Extra Calories if You Switch From Water to Kombucha
If you had a choice between kombucha and soda, kombucha would be the clear winner in terms of both its nutrient profile and added sugar content. According to Coca-Cola, there are 39 grams (g) of sugar in a typical 12-oz can of Coke, and the soda does not supply any essential vitamins or minerals. (12) Meanwhile, kombucha offers gut-friendly probiotics and only about 8 g of sugar per 1-cup serving, depending on the fermentation process, Dr. Zenhausner-Pfeiffer says. (1) (In the kombucha fermentation process, yeast consumes the sugar, leaving some left behind, according to Kombucha Brewers International.) (13)
So while kombucha contains relatively less sugar compared with soda, it is not sugar-free, like tap or unsweetened sparkling water. While sugar alone isn’t responsible for weight gain, eating too much can contribute, according to a review. (14)
7. Kombucha Could Trigger an Allergic Reaction in Some People
Problems could also arise if you’re allergic to kombucha tea. Signs of an allergic reaction vary from person to person, but might include shortness of breath, throat tightness, nausea, and dizziness after consuming the drink. (1,2)
Who Shouldn’t Drink Kombucha?
Be mindful that while kombucha might be beneficial for some people in moderate amounts, certain people should avoid it.
To be clear, there haven’t been any large-scale studies examining the effects of kombucha in pregnancy or while breastfeeding, and a definitive recommendation has not been reached, says Casey Seiden, RD, CDE, a registered dietician and certified diabetes care and education specialist based in New York City. Some pregnant women might choose to avoid kombucha because there’s a small amount of alcohol from the fermentation process. (2) Others may consult their doctor and find it’s safe to drink during pregnancy.
“Pregnant women are advised to not consume any alcohol-containing beverages; however, given the very small amount present, drinking kombucha is seen as a personal choice, with the guidance of your doctor, during pregnancy,” explains Seiden. For this same reason, one study from 2022 recommended that children ages 4 or younger should not drink kombucha.
Because of the acidic nature of the beverage, those who have liver or kidney disease should also avoid kombucha. Additionally, people who have a compromised immune system, such as the elderly and those with HIV or cancer should avoid kombucha, warns Seiden. “This beverage is unpasteurized, so it could lead to food poisoning–like illness,” she continues. (1,2,3)
To err on the side of caution, you may also choose to avoid this beverage if you have an alcohol dependency.
How Much Kombucha Is Safe to Drink?
As with anything, moderation is key. This guideline also applies with kombucha. So while it’s safe to drink occasionally, a general recommendation is that you should limit your intake to 12 oz or less per day. (2)
“If you suffer from digestive upset following excess carbonation, you may want to limit your kombucha to one small glass daily to reap the probiotic benefits, but save yourself some bloating discomfort,” advises Seiden.
You can drink store-bought kombucha, which is available in different flavors, or make your own at home with an online tutorial. If you’re shopping for kombucha, there are no hard-and-fast rules regarding how much sugar is too much in a bottle, though you can cut your intake by opting for a variety without added fruit juice. If you’re concerned about your weight and overall health, consider how kombucha fits into your calorie and sugar intake for the day, says Seiden.
“The good thing is that there are many brands out there of varying calorie and sugar levels, so you can likely find one that helps you meet your goals,” she says.
If you’re up for a challenge and want to make your own kombucha tea at home, there are plenty of recipes you can follow. There are even homemade kombucha kits that include essential ingredients like SCOBY (symbiotic culture of bacteria and yeast), which helps with the fermentation process. This is the thick liquid that floats at the top of a batch of kombucha. (2) You can purchase SCOBY, or use leftover SCOBY from a previously brewed batch.
An example of a simple recipe: (15)
- Boil 4 cups of unchlorinated water
- Add 8 tea bags (black or green) and 1 cup of sugar
- Let the tea steep for 15 minutes, and then strain any loose tea
- Add 12 cups of cold water, pour the tea into a glass jar, and add 1 kombucha SCOBY
- Use paper towel to cover the jar and secure the towel with a rubber band
- Allow tea to ferment for about 7 to 10 days
Always start with a clean pot. “The biggest concern with brewing kombucha at home is cleanliness. If proper cleaning precautions aren’t taken, the risk of molds or harmful bacteria growing are increased, which could lead to illness,” cautions Seiden. “To help decrease these risks, use only glass containers (versus metal) and keep an eye on the color and smell of the SCOBY. If the starter starts to grow black or green spots, or it starts to smell rancid, it’s time to toss that SCOBY and start again with a new one.”
Also, you can use pH strips to ensure you ferment to a pH of 2.5 to 3.5, since under- and overfermenting can both be dangerous. (14)
A Final Word on Kombucha Side Effects
Kombucha might be the secret ingredient to improve your gut health, fight inflammation, and help you feel better. But drinking too much can have adverse side effects, causing more harm than good.
So only consume Kombucha in moderation. Whether you’re buying the drink or making your own, make sure it has the right pH level and is steeped in a safe container.

Kombucha side effects and how to consume it safely
Kombucha may have health benefits due to the beneficial bacteria it contains. But consuming the wrong kind of kombucha, or too much of it, may produce harmful side effects.
Kombucha is a probiotic drink made from fermenting tea and sugar, sometimes along with other ingredients.
Kombucha may have some possible health benefits when consumed in moderate amounts, but drinking too much may carry some risks.
Other issues such as contamination or over-fermentation may also play a role in the possible side effects of kombucha, and there are some characteristics to look out for when choosing a kombucha drink.
This article explores the possible harmful side effects of kombucha, and how to consume it safely.
Share on PinterestPhoto editing by Lauren Azor; Olga Pankova/Getty Images
Kombucha is a traditional fermented drink.
At its simplest, kombucha contains brewed tea and sugar. Many manufacturers add other ingredients for flavor, such as fruit, herbs, or juices.
Leaving the combination to ferment in a controlled environment allows healthy bacteria and yeasts to build up in the drink, making kombucha an easy source of beneficial probiotic bacteria.
The drink may also be carbonated, either through natural fermentation or artificially. The result is a bubbly drink that may have some health benefits.
Research posted to the Journal of Chemistry notes that the probiotics and antioxidants in kombucha may have a number of therapeutic benefits, such as helping support a healthy gut microbiome, as well as supporting other organs and body systems such as the liver, heart, and nervous system.
Although kombucha may have health benefits, there is some possibility for side effects from drinking it.
Digestive upset
Some people may experience digestive upset when drinking kombucha, or from drinking too much.
Symptoms such as gas, nausea, and vomiting may occur. These side effects may be more likely in people who drink too much kombucha.
Additionally, some people may not tolerate kombucha well, or have a poor digestive reaction when drinking it.
Excess calories
Some people drink kombucha as a sweet, carbonated alternative to soft drinks.
While kombucha may provide some benefits to the body, it does contain calories. The actual levels of calories in kombucha will vary widely based on manufacturer and additives.
Some manufacturers may add more sugar or sugar-rich juices to their kombucha for flavor. This also adds calories.
People on calorie-restrictive diets may wish to avoid the extra calories from kombucha.
People with diabetes will also need to be aware of the calories and the carbohydrate and sugar content of kombucha.
Added sugars
The fermentation process from kombucha requires sugar to feed the probiotic bacteria in the drink.
Many manufacturers will also add additional sugars or sugar-rich fruits and juices to the drink.
Sugar-sweetened beverages have links to a number of health conditions.
For example, research posted to Circulation notes the association between sugar-sweetened beverage consumption and conditions such as obesity, type 2 diabetes, and cardiovascular disease.
Additional research in the European Journal of Nutrition notes that people who drink more sugar-sweetened beverages have a higher risk for nonalcoholic fatty liver disease.
Opting for kombucha products lower in sugars may provide the same health benefits with fewer of the risks associated with excessive sugar consumption.
Tooth erosion
Drinking too much kombucha may not be good for the teeth.
As research posted to Beverages notes, the fermentation process of kombucha creates acids such as acetic acid. This is the same acid found in vinegar, and gives the kombucha its tangy flavor.
The release of acetic acid during the fermentation process decreases the pH level of the drink, making it acidic.
Research posted to the Journal of Chemistry notes kombucha has a pH lower than 4.2. Because of this, drinking too much kombucha may put the teeth at risk of erosion.
For this reason, drinking water or rinsing the mouth with water after drinking sweetened acidic beverages may help protect tooth enamel.
Infection risk
Kombucha may not be right for people with sensitive immune systems in some situations.
For example, home-brewed or small-batch kombucha may not have gone through the pasteurization process.
A mix of different types of wild bacteria and yeasts may grow in the drink.
While many of these microbes may be beneficial, the same environment during fermentation may also allow some harmful microbes to grow or leave space for these microbes to take root.
For this reason, people who are prone to infection, such as those with a weakened immune system or chronic conditions affecting their immune system, may want to avoid kombucha.
Excess caffeine
Kombucha typically contains tea during the fermentation process.
Depending on the type of tea, this could provide a person with a lot of added caffeine.
For those sensitive to caffeine or who already drink caffeinated beverages, adding kombucha may increase caffeine consumption and cause symptoms such as:
- anxiety
- irritability
- headache
- dehydration
- trouble sleeping
- fast or uneven heartbeat
- heartburn
- stomach upset
- diarrhea
- nausea
- muscle tremors
- high blood pressure
People who are sensitive to caffeine may want to avoid kombucha or look for versions made without caffeine from tea leaves.
Liver toxicity
Although rare, some people may have more severe reactions to kombucha.
Research posted to SD Med attributes some cases of toxicity of the liver and inflammation to kombucha consumption. These may lead to complications such as jaundice or lactic acidosis.
Those with conditions affecting the liver may want to avoid kombucha or ensure it comes from a controlled environment.
Contamination
As kombucha is a result of natural fermentation, improper handling or poor control of the environment may lead to contamination.
Kombucha contaminated with other bacteria or yeasts may not be as healthy, or may even be dangerous to drink.
Contamination from a container may also be a risk factor. Porous pots, or resins or glazes that contain lead or other contaminants, may leech into the kombucha.
Some plastics may break down into the kombucha as it brews. Contaminants from the container may put the person at risk for side effects or toxicity depending on the chemical.
Safe consumption of kombucha may help reduce some risk factors from the drink.
For small-batch brews or homemade kombucha, ensure the container will not break down or leech chemicals or metals such as lead into the drink.
It is best to brew kombucha in a glass container that can be sanitized before use.
Preventing contamination from other microbes may include proper temperature control and the use of clean equipment during brewing.
For those worried about the possibility of other microbes in the drink, look for pasteurized kombucha. Some manufacturers will pasteurize the drink and then add only beneficial bacteria afterward.
For those concerned with sugar and calorie intake, look for drinks that do not contain too many added sugars or calories.
There is no set recommendation for kombucha consumption.
Individual factors and the type of kombucha may vary greatly.
With this said, drinking one to two 8-ounce servings of kombucha each day may be suitable for average consumers.
Kombucha is a fermented probiotic tea that may be beneficial to the body.
There are some risks to consider, especially when drinking kombucha in excessive amounts.
Some people may want to avoid kombucha, such as those with compromised immune systems and people sensitive to caffeine.
There are no exact guidelines on kombucha consumption, and finding a way to balance individual consumption may be best in each case.
7 Reasons to Drink Kombucha Every Day
Sparkling, fragrant, somewhat champagne-like, the increasingly popular Kombucha drink is available in health food stores and some restaurants. In fact, Kombucha is our good old friend, “longevity drink”, as they call it in China, or simply – an infusion of kombucha. This is an unpretentious pet of our grandmothers, popular in traditional medicine, but somewhat forgotten in recent decades and supplanted by purchased sodas and drinks from Starbucks.
Kombucha (Kombucha infusion) is a lightly carbonated fermented drink made from tea leaves (or coffee) and sugar, which acquires a sour taste and a host of health benefits. At the beginning of the 20th century, Russian and German scientists carefully studied the properties of kombucha, but science has yet to reveal all the secrets of this amazing culture. The second birth of Kombucha was given by the development of microbiology. Research conducted as part of the Human Microbiom Project has proven that the human microflora directly affects our well-being, appearance, and even food preferences. The culture itself has little in common with ordinary mushrooms and looks like a jellyfish. Despite the unusual appearance, there are many reasons to make friends with kombucha.
In this article, Yuliya Maltseva, detox specialist, author of the blog Yogabodylanguage.com, and virtuoso fermentalist, will talk about her secret recipes and why you should drink kombucha every day.

Reason 1: Kombucha is the best replacement for bad soda
As a rule, store-bought soda contains a ton of sugar, preservatives and dyes. Homemade kombucha is a good alternative to unhealthy store-bought drinks. The basic infusion of kombucha itself has a pleasant refreshing taste that can be varied with fruits, berries and spices. Carbonation is formed in kombucha drink due to natural fermentation and will not cause bloating and other troubles, unlike artificially carbonated drinks.
“But what about sugar?” – you ask. Sugar is indeed added to kombucha as it is needed to start fermentation, but it is taken up by the yeast so there is virtually no sugar in the final product. You can also use unrefined cane or coconut sugar instead of regular white sugar to make kombucha. The benefits of this drink are undeniable.
Reason 2: Kombucha is a detox drink
The tea’s antioxidants, vitamins, micronutrients, and especially the acids in the infusion support cleansing and normal liver function. To further enrich kombucha with phytonutrients – natural substances from plants that support the health of various systems and organs – add fresh berries, fruits and juices to the infusion.
Reason 3: Kombucha improves digestion
Due to the content of probiotics, enzymes and useful acids, kombucha has a beneficial effect on the activity of the gastrointestinal tract, normalizes the acidity of the stomach, and heals the intestinal microflora. This is especially true in the summer during intestinal infections. Add mint and lemon to the kombucha infusion – they will additionally stimulate the secretion of gastric juice and digestion.
Reason 4: kombucha boosts immunity
Kombucha will help you stay healthy in any weather, even if the summer turned out to be capricious, but you want to spend more time in nature. It supports healthy intestinal microflora, the composition of which determines the body’s immune response by 80%. Try a kombucha infusion with ginger root or turmeric for a metabolic boost and an anti-inflammatory effect.
Reason 5: increased energy levels
The tonic effect of kombucha is due in part to the tannin from the tea, which has a milder effect on the central nervous system than caffeine. But the real charge of vivacity is given rather by the rich nutrient and vitamin composition of kombucha. For those who like to “cheer up”: try kombucha brewed with coffee. The caffeine from this drink is not going anywhere, but along with kombucha you will get a serving of vitamins and probiotics – an advantage over Starbucks coffee and energy drinks.
Reason 6: alternative to alcoholic beverages
Instead of sugary and high-calorie alcoholic beverages that slow down your metabolism and often have side effects, try spiced fizzy kombucha. The finished infusion contains a small amount of alcohol, which is quite enough to lift the mood without a headache. Try kombucha mojito: kombucha infusion + lime + mint. Wonderfully refreshing!
Reason 7: Kombucha helps you lose weight
A 2005 study indicates that kombucha improves metabolism and reduces body fat. Of course, more research is needed in this area in order to draw firm conclusions. However, kombucha has such a rich taste and rich composition that the feeling of hunger after a glass of kombucha recedes for a long time. Kombucha with chia seeds will help you deal with sudden feelings of hunger and subsequent overeating and unhealthy snacking.
A few general tips:
1) The infusion of Kombucha has a number of contraindications that you need to familiarize yourself with.
2) When choosing a culture of Kombucha, pay attention to its quality and the experience of the seller. It is advisable to purchase kombucha with certificates of conformity and safety of consumption.
3) Kombucha is unpretentious, but still requires care and attention. If you want to grow a mushroom at home, it is advisable to enlist the help of more experienced fermenters.
