Live cultures are probiotic bacteria that contribute to good gut health. Fix8 adds science-backed strains specifically selected for targeted gut release — meaning they survive the journey to your gut, not just your mouth.

Water kefir contains millions of probiotics, which can help:

• support the balance of your gut microbiome

• aid digestion

• reduce bloating

• improve nutrient absorption

• support immune function

We want to give you the maximum gut health benefit from drinking our kombucha’s. We know that not a lot of kombucha in cans have surviving bacteria left in them sadly. So we wanted to go above and beyond. Our added live cultures are science-backed, so you get a double hit of goodness for your gut, and we can prove it.

Having adequate vitamin C is one of the easiest ways we can top up our immune health! In a post-pandemic world, we thought it could only do the drink (and you) more good.

Kombucha is a fermented tea drink originating from Asia thousands of years ago, where it was known as the 'tea of immortality'. It's made using four simple ingredients: tea, water, sugar, and a SCOBY (symbiotic culture of yeast and bacteria). The fermentation process converts the sugar into organic acids and live cultures — leaving a naturally sparkling, tangy drink that's low in sugar and good for your gut.

KOM-BOO-CHA. Now practise 3 times.

Fix8 is non-alcoholic.

There is a teeny tiny amount of sugar in our kombucha’s as it is an essential part of the kombucha fermentation process. But it’s not in there for you, it’s in there for the yeast and bacteria to live off and allow fermentation to happen. No sugar = no fermentation = no kombucha! Without sugar, there is also nothing to keep the bacteria alive and they will (sadly) die off. Be wary of ‘zero sugar’ kombuchas.

We have a low-calorie content (between 30-36 calories per can) and use absolutely no sweeteners or flavour modulators such as erythritol. Call us purists, but we prefer our totally kombucha natural.

If you’re eating live foods such as kefir, yoghurt or taking probiotics – you are most likely fine to consume Fix8. However, it is always safer to consult your doctor before consuming if unsure.

You can pop our drinks in a cool place away from sunlight. Make sure you store them in the fridge before drinking though. This is very important!

12-18 months. But to be sure, check the base of our can.

We suggest drinking ice-cold. Any time of day but we like it best as an afternoon ‘cold can moment’. Pour into a glass over ice or drink straight from the fridge. Our founder Freya loves drinking it out of a wine glass in the evening instead of alcohol. But, if you’re prone to a tipple, our Fix8 Kombucha’s are a great mixer with any spirit. Try: Fix8 Ginger Turmeric + Vodka for a ‘modern Moscow mule’!

Beyond the exciting look of our cans and and delicious (unique) flavours – our true stand out quality is the combination of quality kombucha alongside science-backed live cultures. To top it off, we add vitamin C for immune health. No other kombucha in the UK has this combo and we’re super proud of that.

Water kefir is a naturally fermented, lightly fizzy drink made using kefir cultures — a mix of bacteria and yeast — that ferment natural fruit juice. The result is a refreshing drink filled with live cultures, healthy acids, and natural probiotics, with no added sugar.

Most people say “keh-feer” or “kee-fur.” We’re not precious — drink it however you say it.

Unlike dairy kefir, FIX8 Water Kefir is 100% lactose-free, fruit-fermented, raw, unpasteurised, vegan, and naturally low in sugar because we ferment real fruit juices rather than adding refined sugar. It’s a lighter, fresher take on kefir — more like a juicy, gut-loving soft drink.

Yes — water kefir is naturally gluten-free, and our drinks use no gluten-containing ingredients.

No. Water kefir is naturally caffeine-free — there’s no tea used in the process.

No — it’s raw and unpasteurised, meaning the live cultures stay alive and active.

There is no added sugar. Any sweetness comes solely from the natural fruit juice, and much of that sugar is consumed during fermentation.

Water kefir is a non-alcoholic, pasteurisation-free fermented drink. Many people enjoy fermented products during pregnancy, but because every pregnancy is unique, we recommend checking with your healthcare provider.

Water kefir originates from Mexico, where cultures were traditionally fermented with fruit to create a refreshing, naturally sparkling drink. The heritage of fermentation inspired our approach and flavour choices.
