Our quality promise, and what each product contains
At a glance
Natural Probio cultures are live cultures from traditional strains, selected for their vitality and guaranteed alive on arrival. Each pouch holds a single ingredient, the live culture itself, with no additives, in a sealed pouch and protective packaging. Every order includes a starting guide and access to our recipes, and the activity of your grains is covered by a lifetime guarantee.
A living culture is not like a jar of jam that sits happily on a shelf. It has to arrive in good shape, start working in an unfamiliar kitchen and keep going for as long as you look after it. So rather than vague adjectives, here are the specific commitments we make, and the exact contents of every product in the range.
Six things we commit to
Carefully selected cultures
Traditional strains from time-honoured methods, chosen for their vitality and their consistency from one jar to the next.
Alive when they reach you
We only send live, active cultures, and their arrival is guaranteed. If they do not start, we replace them at no cost.
Nothing added
Inside the pouch there is one ingredient: the live culture in its own liquid. No additives, no fillers.
Built to travel
A sealed pouch, protective packaging and dispatch within 24 to 48 hours with tracking.
Clear instructions
A starting leaflet, a complete guide and recipes, so you know what to do the moment you open the box.
A lifetime guarantee
If your grains, used and kept in normal conditions, stay inactive, we replace them at no cost.

Water kefir, ingredient by ingredient
The water kefir pouch contains one ingredient: live water kefir grains. The drink you make with them is water, sugar, fruit and whatever the grains turn that into overnight. There is no milk and nothing of animal origin in it, which makes it suitable for people avoiding dairy and for those following a vegan diet. Like every homemade fermented drink, it contains traces of alcohol, generally under 0.5%.
You stay in control of the rest: the type of sugar, the fruit, the herbs and spices you add at bottling time. The guide explains which choices make a softer drink and which make a livelier one, and our flavour ideas show how far you can take it.
Help is part of what you buy
A live culture comes with questions, especially in the first week. Our team replies personally within one working day, in English, German, Italian or Spanish, and very often on the same day. A photo of your jar is usually enough for us to tell you whether all is well, and if it is not, the guarantee steps in. Customers mention this more than anything else: "We had a question about activating the kefir and immediately got a helpful and kind reply," wrote Wibke S. on Trustpilot (translated).

Questions about quality
Are there any additives in the pouch?
No. The pouch contains the live culture in its own liquid and nothing else.
How do I know my grains are alive?
They are sent alive and active, and you will see small bubbles in your jar within a day or so of starting. If they stay inactive, the guarantee covers a replacement at no cost.
Is the finished drink dairy-free and vegan?
Yes. Water kefir is made from water, sugar, fruit and the grains, with no milk, no lactose and nothing of animal origin.
