As elaborated?

This drink is made by dissolving these ingredients from organic farming in water: cane sugar*, concentrated lemon juice*, date puree*, matcha tea powder and probiotic cultures that consume the sugars to grow (strains of the Lactococcus genera , Lactobacillus and Bifidobacterium).

This kefir is stabilized by HPP, maintaining a smooth and fresh flavor for a very long time without the need for a refrigerator. Plus they don’t have gas.

Why does it have sugar?
Sugar is the food of kefir cultures, it disappears before packaging. The soft drink contains less than 2% sugar and a 400 ml bottle has less than 70 kilocalories.

IDEAL for athletes and feelings of continuous fatigue.

If you are consistent and take Prokey for 7-10 days you will notice its results.

On our label you can see the nutritional characteristics of our soft drink.


PROKEY is a fermented drink. You should not be scared by the word fermentation, we consume many fermented foods such as cheese, many sausages or olives. Beer and wine are also fermented foods.

The preparation of PROKEY water kefir soft drink is halfway between that of yogurt and that of beer or wine since the probiotic cultures in kefir are a mixture of lactic acid, acetic bacteria and yeasts. For the kefir culture to grow in PROKEY it is necessary to feed it correctly. At PROKEY we make it with sugar and dates. Kefir uses up the sugar and many nutrients in dates and generates organic acids and many other compounds (see more). We carry out this process in stainless steel tanks similar to beer fermenters.

This is what the fermentation process consists of. The end result is PROKEY, a delicious organic soft drink full of healthy compounds and live probiotic microorganisms, very low in calories and almost sugar-free since kefir has consumed it.

We use certified organic ingredients so our soft drink is also organic. To get our AQUA flavor we use lemon, which we add to the mixture during and releases its essence into the soda throughout the process. It gives a very special touch to the flavor of PROKEY. Later we can add infusions or fruit juices to obtain different flavors such as PROKEY GINGER&MINT.

“I use it daily and notice clear improvements in digestion and rehydration”

“I discovered it through a couple of colleagues and after informing myself, today is the day I use it daily. It is my substitute for more commercial soft drinks that are unhealthy. I use it mid-afternoon and have noticed clear improvements in digestive processes and hydration mid-afternoon.
