Gut Health: How to Support Your Microbiome with Delicious Kombucha

It’s no secret that 2025 is the year of “gut health”. The four Ks; Kefir, ‘Kraut, Kimchi, and Kombucha have been promoted by esteemed doctor, Dr Tim Spector, for a number of years. He knows all about the best everyday ways to support your microbiome and has been leading the charge with the promotion of good gut health. 

Your gut is home to trillions of microorganisms that play a crucial role in digestion, immunity, and even mental health. Outside of the four Ks there are many nutritional, mindful, and physical ways to look after your gut health. We’ll give the scoop in this blog post. 

Kombucha is a powerful, daily tool in supporting your gut health. The lightly effervescent, fermented tea is more than just the latest trend in the drinks world. It is a powerhouse of healthy bacteria and acids that may give your gut a major boost.

What is Kombucha?

Kombucha is a naturally fermented tea made from sweetened tea and a symbiotic culture of bacteria and yeast, commonly known as a SCOBY. During fermentation, the SCOBY consumes the sugar in the tea, producing beneficial organic acids, healthy bacteria, and an effervescence that makes kombucha so refreshing.

How Kombucha Benefits Gut Health

1. Rich in Healthy Bacteria and Acids

One of the biggest gut health benefits of kombucha is its high content of healthy bacteria and acids. These are live microorganisms that add to the diversity of your gut microbiome. A healthy, diverse microbiome can improve digestion, boost immunity, and even enhance mental well-being.

2. Supports Digestion

The fermentation process produces organic acids, such as acetic, lactic, and gluconic acids, which can aid digestion. These acids help maintain a healthy gut pH and may assist in breaking down food more efficiently.

3. Promotes a Balanced Microbiome

An imbalance in gut bacteria (known as dysbiosis) can lead to digestive issues, inflammation, and even mental health challenges. The compounds in kombucha can help restore balance by promoting the growth of beneficial bacteria and inhibiting harmful ones.

4. Potential Anti-Inflammatory Effects

Kombucha contains polyphenols from tea, which have antioxidant and anti-inflammatory properties. Since chronic inflammation in the gut can contribute to conditions like irritable bowel syndrome (IBS), adding anti-inflammatory foods and beverages to your diet, including kombucha, may be beneficial.

How to Choose the Right Kombucha 

Not all kombuchas are created equal. You may find kombucha in your supermarket that claim to be ‘sugar-free’. However, you need sugar to make kombucha. The sugar is ‘eaten’ by the SCOBY during fermentation, kombucha is naturally low in sugar. Adding sweeteners tips a healthy product into being an ultra processed food and one that will not support gut health. 

You’re looking for a liquid that has a tang, Left Field is naturally savoury, but the culture has been developed to remove the overbearing vinegaryness sometimes found in kombucha. Some brands add vinegar to artificially create the tang. Check the label! 

If you see sediment in the bottle, or even a jelly-type substance (it’s called a pellicle), this points to kombucha having all the good stuff left behind. 

Other Ways to Support Your Gut Health 

🌿 Aim for 30 plants per week. Easy ways to incorporate include lentils and beans instead of meat, mixed leaves rather than solo spinach, or pair your kombucha with some spiced nuts and seeds, or crudites with hummus. 

🧘🏻 Reduce stress where possible. Take five minutes out to practice some meditation. Grab a kombucha and tune into Stuart Sandeman’s Breathpod.

😴 Rest is crucial to reducing stress. It has been found that lack of sleep can affect gut health, so catch those zzzs when you can.

🚶🏻 Get out for a 30 minute walk or exercise. This can aid digestion and support bowel movement. The Italians do it best taking la passeggiata after dinner.
