Can You Drink Too Much Kombucha?

Kombucha has fizzed its way into cafés, delis and fridges across the UK. People enjoy it for its tang, its gentle sparkle and the way it swaps out a sugary soft drink for something a bit lighter. But a common question is: can you drink too much kombucha?

The short answer

Yes, like most things, it’s possible to overdo it. For most people, a moderate amount is fine and can be a pleasant part of an everyday routine. But drinking very large quantities regularly may bring unwanted effects for some.

Why people reach for kombucha

Kombucha is made by fermenting tea with a culture of bacteria and yeast (commonly called a SCOBY). The result is a naturally fizzy drink that might offer a few extras:

• Live cultures: often associated with gut health in popular writing, though evidence is still developing.
• Organic acids: which some people find may support digestion.
• Polyphenols and antioxidants: compounds that come from the tea used to brew kombucha.
• A gentle lift: a small amount of caffeine depending on the tea base.

How much is too much?

If you’re new to kombucha, try starting with a small pour (around 100–200ml) and see how you feel. Some people happily have up to a single bottle (~330ml) a day; others prefer smaller, occasional servings.

Drinking substantially more than that on a regular basis could lead to a few issues:

• Tummy discomfort: kombucha is acidic and fizzy, which can upset sensitive stomachs.
• Extra sugar: home-brewed and commercial kombuchas can both contain residual sugar, so check labels if you’re watching your intake.
• Caffeine accumulation: although less than a cup of tea or coffee, the caffeine adds up if you drink several bottles a day.
• Not suitable for everyone: people who are pregnant, breastfeeding, have certain medical conditions, or are immunocompromised may wish to speak with a healthcare professional before drinking kombucha regularly.

Simple ways to enjoy kombucha sensibly

• Ease in: start with a small serving to see how your body reacts.
• Mix it up: alternate with water or herbal tea so kombucha isn’t your only daily drink.
• Read the label: sugar and alcohol levels differ by brand, pick what suits your preferences.
• Trust your body: if you notice bloating or other symptoms, scale back and consider seeking advice from a GP or pharmacist.

The takeaway

Yes, you can drink too much kombucha. For most people in the UK, sensible portions enjoyed as part of a varied diet are perfectly reasonable. Think of kombucha as a tasty, fizzy option to enjoy in moderation rather than a cure-all.
