In the realm of gut health, you’ve definitely heard of these two popular buzzwords – Kombucha and Probiotics. In this blog post, we’re getting into the topic of Kombucha vs Probiotics, both touted for their potential benefits in supporting a healthy digestive system, but they come from different origins and offer slightly different things. We’ll explore exactly what they are, where they come from, and which might have more beneficial effects for your overall health.

What is Kombucha?

Kombucha is a fermented tea beverage that gained popularity for its potential health benefits. It’s made by fermenting sweetened tea with a symbiotic culture of bacteria and yeast (SCOBY). The fermentation process results in the production of probiotics, organic acids, enzymes, and trace amounts of alcohol, giving Kombucha its unique taste and fizzy nature. Probiotics are what give kombucha its potential health benefits, so you can’t really compare kombucha and probiotics. Instead, we have to compare kombucha to other probiotic sources, which will do down below. For now, more on kombucha.

To make Kombucha, green tea or black tea is typically used, and it’s sweetened with sugar. The SCOBY, often referred to as the “mother,” is added to the sweetened tea and left to ferment for a period of time, usually one to two weeks. During fermentation, the SCOBY consumes the sugar, producing carbon dioxide, which gives the drink its effervescence.

Kombucha is known for its tangy flavor, and it can be further flavored with fruits, herbs, or spices during a second fermentation phase. While many people enjoy Kombucha for its taste, it is also believed by some to have potential health benefits due to its probiotic content, which may support gut health.

Potential Side Effects of Kombucha

It’s important to note that kombucha can have adverse side effects. Unfortunately, there have been no controlled human studies of kombucha tea, and there are quite a few claims that these probiotic drinks can cause dangerous side effects like severe metabolic acidosis, hepatotoxicity, and more, so the potential for harm seems pretty considerable. Individual experiences with Kombucha can vary, and some caution should be exercised, especially for those with certain health conditions or compromised immune systems. Also, homemade Kombucha should be prepared with a lot of care to avoid contamination.

What are Probiotics?

On the other hand, probiotics are live microorganisms that offer health benefits when consumed in adequate amounts. These microorganisms, often referred to as “good” or “friendly” live bacteria, can be found in various fermented foods and supplements. Common strains include Lactobacillus and Bifidobacterium, which are naturally present in the human digestive system. The beneficial probiotics found in kombucha are the good bacteria that give the drink its health benefits. Probiotics can also be found in the following:

Plant-Based Probiotic Foods:

  • Sauerkraut: Fermented cabbage.
  • Kimchi: A Korean fermented dish usually made with cabbage and radishes.
  • Miso: A Japanese seasoning produced by fermenting soybeans with salt and koji.
  • Tempeh: Fermented soybean product with a firm texture.
  • Natto: A Japanese dish made from fermented soybeans.
  • Pickles (fermented in brine): Naturally fermented pickles, not pickled in vinegar.
  • Kombucha: Fermented beverage, often flavored.
  • Yogurt alternatives (plant-based): Almond, soy, or coconut milk-based yogurts with added probiotics.
  • Fermented miso soup: Soup made with miso paste that retains live probiotics.

Other Sources (Including Animal Products):

  • Yogurt: Dairy-based yogurt containing live and active cultures.
  • Kefir: A fermented dairy drink made from milk and kefir grains.
  • Buttermilk: Fermented dairy product with live cultures.
  • Sour Cream: Fermented cream with live cultures.
  • Cheese: Certain types of cheese, such as gouda, cheddar, and mozzarella, can contain probiotics.
  • Traditional Pickles: Pickles made through natural fermentation with live cultures.
  • Fermented Soy Products: Besides tempeh, other fermented soy products like tofu may contain some probiotics.
  • Traditional Fermented Foods: In various cultures, there are traditional fermented foods that may contain probiotics, such as injera (Ethiopian fermented flatbread).

When choosing foods for their probiotic content, opt for those that are naturally fermented and mention the presence of live cultures for maximum probiotic benefits.

Dietary Supplements:

  • Capsules/Tablets: Probiotic supplements are often available in capsule or tablet form, containing a concentrated dose of probiotic bacteria.
  • Powders: Some probiotic supplements come in powder form, which can be mixed with water, juice, or food.
  • Softgels: Probiotic softgels are another form of encapsulated probiotic supplements, often preferred by those who may have difficulty swallowing capsules.
  • Chewables: Probiotic supplements in chewable form provide an option for those who prefer not to swallow pills.
  • Gummies: Probiotic gummies are a tasty and convenient way to consume probiotics, particularly popular among children and those who dislike traditional capsules.
  • Liquids: Liquid probiotic supplements can be added to beverages or taken directly. They may come in small bottles with droppers for precise dosage.
  • Probiotic Drinks: Some probiotic supplements are formulated as ready-to-drink beverages, similar to probiotic-rich drinks like kombucha.
  • Yogurt Starter Cultures: These are designed for making probiotic-rich yogurt at home. The starter cultures usually contain specific strains of beneficial bacteria.
  • Prebiotic and Probiotic Blends: Some supplements combine probiotics with prebiotics (fibers that support the growth of beneficial bacteria) for enhanced digestive health.
  • Time-Release Capsules: Certain probiotic supplements are designed with time-release technology to ensure a gradual release of probiotics in the digestive system.

When choosing a probiotic supplement, it’s important to consider the specific strains of bacteria included, the potency (measured in colony-forming units or CFUs), and any additional ingredients. It’s recommended to consult with a healthcare professional before starting any new supplement regimen.

Why Probiotics are Important for Overall Health

Probiotics contribute to a healthy gut microbiome, aiding in the balance of intestinal flora. They support digestion, enhance nutrient absorption, and play a crucial role in immune system modulation. Probiotics have been associated with a range of health benefits, including alleviating irritable bowel syndrome (IBS) symptoms, promoting mental well-being, and even reducing the risk of certain infections.

Potential Side Effects of Probiotics

While probiotics are generally considered safe for most people, they may cause certain side effects in some individuals. It’s important to note that the side effects are typically mild and temporary.

1. Digestive Symptoms

Some people may experience temporary digestive symptoms when starting probiotics, such as gas, bloating, diarrhea, or mild stomach discomfort. These symptoms often improve over time as the body adjusts to the introduction of beneficial bacteria.

2. Allergic Reactions

In rare cases, individuals may be allergic to components in probiotic supplements, leading to allergic reactions such as rash, itching, or swelling. If you experience allergic symptoms, it’s important to seek medical attention.

3. Infections

Probiotics are generally safe for healthy individuals, but people with weakened immune systems or underlying health conditions may be at risk of developing infections. Consult a healthcare professional before using probiotics in such cases.

4. Risk for Certain Populations

Probiotics may not be suitable for everyone, especially those with serious medical conditions. Individuals undergoing immunosuppressive therapy, organ transplant recipients, and those with severe illnesses should consult their healthcare provider before using probiotics.

5. Unwanted Interactions

Probiotics may interact with certain medications. If you are taking medications or have underlying health conditions, it’s advisable to consult with a healthcare professional to ensure there are no potential interactions.

6. Overconsumption

Taking excessive amounts of probiotics may lead to an imbalance in gut bacteria. It’s important to follow recommended dosages and not exceed them without professional advice.

7. Herxheimer Reaction

Some individuals may experience a temporary increase in symptoms as a result of the body detoxifying. This is known as the Herxheimer reaction and is typically short-lived.

It’s crucial to consult with a healthcare professional before starting a probiotic supplement regimen, especially for individuals with pre-existing health conditions or those taking medications. Monitoring your body’s response and adjusting the dosage if needed can help minimize potential side effects.


The debate between Kombucha vs probiotics is not necessarily about choosing one over the other; considering kombucha is just a source of probiotics. It’s about understanding how to achieve great gut health in general. Incorporating a variety of fermented foods, which can include Kombucha (I recommend small amounts), along with other probiotic-rich sources, can contribute to a diverse and resilient gut microbiome. Ultimately, the key to reaping the maximum benefits lies in maintaining a balanced and varied diet that supports overall well-being.
