Dietary restrictions getting you down? Kombucha’s got you, boo

by Brock Goodhill


Ahhhh kombucha, the-tart-but-sweet, refreshingly good-for-you, hella tasty elixir of good gut health *cue angelic music and glowing halo*.

Buuuut is it any good if you’re dealing with dietary restrictions? Maybe you’re wondering:

  • Is kombucha halal?
  • Does it have caffeine?
  • Is it gluten-free? 
  • What about kombucha for FODMAP diets?

If you’ve got dietary restrictions, we’ve got answers we think you’ll like.

To find out whether kombucha really is the perfect drink (and spoiler alert: we reckon it is), read on.

Oh, but before we jump in: a note of caution. As with anything, moderation is key. We don’t recommend downing litres of kombucha at a time. And while we’re true experts in making delicious, good-for-you drinks, none of our team have been to med school. So if you have questions about your dietary requirements or specific health needs, always ask your doctor or nutritionist – not random people on the internet.

What is kombucha?

Let’s quickly cover exactly what kombucha is made from and how it’s produced, so you can make an informed decision about whether it’s right for you.

What’s kombucha made from?

does kombucha have caffeine

Kombucha usually contains three ingredients: 

  • tea
  • sugar
  • live cultures, known as a SCOBY (which stands for Symbiotic Culture Of Bacteria and Yeasts). 

How it’s made

Kombucha-makers combine tea, sugar and the SCOBY, then leave the mixture alone to do its thing (a process known as fermentation). During this fermentation: 

  • the cultures digest all the sugar and caffeine from the source ingredients (especially with longer fermentations like Nexba’s 40-day Brew!) 
  • they produce organic acids, vitamins (in particular, Vitamin B and Vitamin C), minerals, amino acids and enzymes 
  • they also produce happy gut buddies in the form of super-powerful probiotic microorganisms 

Kombucha bacteria and yeasts: are they good for you?

Our bodies contain both good and bad bacteria and yeasts. Kombucha bacteria (aka probiotics) and yeasts are the good guys, and they’re great for our health in so many ways

But the health benefits from kombucha aren’t just about providing probiotic bacteria and yeasts to our bodies. Kombucha also helps to suppress less *ahem* desirable bacteria and yeasts. For example, the abundant tea polyphenols and acetic acid in kombucha have been shown to suppress bad bacteria and yeasts like candida. And they both also have antioxidant properties!

So can people with dietary restrictions drink kombucha?

Ok, now that we’ve covered the basics, let’s jump in and answer all your specific dietary questions.

Is kombucha halal?

We can’t guarantee that all kombuchas are halal, but we can guarantee that Nexba Kombucha meets halal standards. Nexba Kombucha is absolutely natural, and has no animal products (like, none whatsoever: it’s 100% vegan).

And while some kombucha (especially the homemade stuff) can contain trace levels of alcohol - Nexba Kombucha is completely free from alcohol. 

Is kombucha dairy-free?

Yep, sure is! Kombucha has no dairy in it at all, so it’s perfect for anyone who’s dairy- or lactose-intolerant.

Is kombucha good for vegetarians and vegans?

Kombucha is 100% free from animal products. So the answer, of course, is yes! 

Kombucha is great for vegetarians, vegans and anyone who wants to reduce the animal products in their diet for any reason.

Is kombucha caffeine-free?

Because kombucha is made using tea, we can’t speak for all kombuchas. We can, however, definitively say that Nexba Kombucha has zero caffeine whatsoever. 

We take great care in fermenting our kombucha enough to ensure there’s absolutely no caffeine or sugar in the final product – just pure, natural refreshment!

Is kombucha gluten-free?

Again, we can’t guarantee this for all kombuchas. When it comes to Nexba Kombucha, though, you can be sure that there’s absolutely no gluten in our bottles (or anywhere in our production facilities, for that matter).

Coeliacs and gluten-sensitive peeps: we’ve got your back!

Is kombucha alcohol-free?

Generally speaking, most kombuchas contain trace amounts of alcohol, which comes from the fermenting yeasts in the SCOBY. 

Having said that, alcohol levels in kombucha generally are super low. They’re usually similar to what you’d find in overripe fruit or sourdough bread - low enough to barely even register.

And the good news? Nexba Kombucha is actually completely free from alcohol!

Is kombucha good for people with food allergies?

Generally speaking, yes! It’s super-unusual for kombuchas to contain any of the most common food allergens: cow’s milk, peanuts, tree nuts, shellfish, fish, wheat, soy or eggs. (Although, again, the usual disclaimers apply: we can only speak definitively for Nexba Kombucha, not anyone else’s!)

And again, if you have food allergies, please do your own research. Speak to your doctor or health professional about what’s appropriate for you. 

Is kombucha good for people on low FODMAP diets?

In case you didn’t know, FODMAP stands for ‘Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols’. These big scientific names all refer to types of sugars in everyday foods that most of us have a hard time digesting.

For some people, though, the issues go beyond digestion difficulties. For those folks, these sugars trigger some pretty uncomfortable Irritable Bowel Syndrome (IBS) symptoms, including gas and diarrhoea.

Luckily, the clever scientists at Monash University in Australia devised a low FODMAP diet to help people with IBS who have trouble with these sugars.

According to Monash, kombucha can contain fructans (or fructooligosaccharides - the ‘O’ in FODMAP). Because of this, researchers recommend small serving sizes of kombucha for people on a low FODMAP diet. The Monash FODMAP food app can give you guidance on the right serving size for you.

What’s so special about Nexba Kombucha?

If you have dietary restrictions, we know you’ve probably already earned yourself a degree in reading food labels and analysing ingredients. So to make it easy for you to check Nexba Kombucha, here’s exactly what’s in every bottle:

*All sugar has been fully consumed during the extended fermentation process to produce the kombucha.

**Erythritol is naturally produced by fermenting the starches in fruits and vegetables.

Dietary restrictions don’t have to mean missing out

Kombucha is the perfect drink for just about everyone. Don’t believe us? Try it for yourself.

That note of caution again in case you missed it!

As with anything, moderation is key. We don’t recommend downing litres of kombucha at a time. And while we’re true experts in making delicious, good-for-you drinks, none of our team have been to med school. So if you have questions about your dietary requirements or specific health needs, always ask your doctor or nutritionist – not random people on the internet.
