With our Weide Whey we have already proven that dietary supplements can not only be 100% pure & natural but also sustainably produced. To take that even further we created a protein supplement that ideally supplements your microbiom with bifidobacteria.
Fermented whey protein vs. conventional whey protein
Whey protein comes in three different quality levels: concentrate, isolate and hydrolyzate – currently the purest and most easily digestible wheyprotein. The big disadvantages: hydrolyzate is very expensive to produce and has a bitter taste.
Kefir whey constitutes a new generation of whey protein. It combines the best properties of hydrolyzate with a pleasantly neutral taste, creamy texture, more than 90 grams of protein and an affordable price.
Just like hydrolyzate the protein chains are broken into di- & tripeptides. These short-chain proteins are absorbed more quickly and efficiently by the body. Kefir Whey thus achieves level of protein uptake comparable to hydrolyzate. An absolute game changer!
The differences and similarities between whey protein hydrolyzate and fermented whey protein
- Both (pure) hydrolyzate and fermented whey protein contain a very high protein content of over 90% and can be considered the purest form of whey protein.
- Both forms are sugar-free, fat-free and lactose-free.
- Both have in common that they can be metabolized very quickly and efficiently by the body due to the fermentation induced protease.
- While (pure) whey protein hydrolyzate tastes very bitter, Kefir Whey is pleasantly neutral and milky.
- Both hydrolyzsate .
Biological value and high bioavailability of the fermented whey protein
Whey proteins are among the foods with the highest biological value. By splitting it into short-chain peptides, Protero Kefir Whey is also characterized by high bioavailability and a unique amino acid profile. The essential amino acids account for 26.87%.
Additional benefits of fermentation
Fermented milk products are very different from non-fermented milk products. Undesirable components from the whey are converted during the natural fermentation and are hardly or not at all present in the end product. An example of this is lactose. Therefore the Kefir Whey is lactose-free.
At the same time, fermentation increases complexity and nutrient density, as the kefir cultures produce additional nutrients.
State-of-the-art manufacturing processes combined with the ancient art of fermentation
In the most modern plants of our raw material supplier, pasture milk from the surrounding area is made into whey and this natural kefir cultures are added. The fermentation takes place for 12-18 hours at 25°. The whey then goes through cold filtration in the ceramic filter and becomes whey. Through further, finer filtration, the whey loses the lactose and fatty acids, so that the protein content increases further.
After spray drying, a lactose-free whey isolate protein powder remains of the highest quality with a protein content of 91g.

Not just for athletes
Protein supplements are no longer just for bodybuilders, gym goers or athletes. Whether as part of a low-carb or Atkins diet, protein powders can support and facilitate a protein-rich diet. So the Kefir Whey Protein can not only be taken as a protein shake. It can also be used as a baking protein and ingredient for various dishes.

Suitable for a Paleo/Primal diet
In the transitional period to agrarian societies, the Neolithic Revolution, fermented foods and beverages were already available to hunter-gatherers. With the Protero Kefir Whey you can follow a Paleo-calculated diet without having to do without a powerful dietary supplement. If not Paleo it certainly is a Primal Whey indeed.
Game changer protein with the usual taste & texture
The new Protero Kefir Whey does not lack the creaminess known from Weide Whey. It tastes slightly milder and more neutral and mixes very well. Anyone expecting the taste of kefir will be disappointed. The Protero Kefir Whey does not show a sour note due to the microfiltration to whey isolate .
The Kefir Whey Protein is unique in its production and inner values but builds on the usual taste and texture of a conventional high-quality protein powder. So put the article in the shopping cart and you will soon be able to enjoy a real game-changer protein.
