Grass-Fed Whey Protein Isolate – fast‑absorbing natural whey protein isolate sweetened with stevia – low in sugar and fat

Grass-Fed Whey Protein Isolate – fast‑absorbing natural whey protein isolate sweetened with stevia – low in sugar and fat
From the milk of free‑range cows on Dutch meadows
The basis of our isolate is high‑quality whey. We obtain it from the milk of cows that are grass‑fed for at least 10 months of the year. As a result, the milk has a more favourable fatty acid composition compared to the milk of cows that receive a compound feed, and this is reflected in the resulting protein quality.
The whey is then filtered at low temperatures to retain the valuable protein fractions in the protein. It contains naturally occurring protein fractions such as ß-lactoglobulin and lactoferrin, which are beneficial components of whey.
Maximum usability for your body
Your body gets the most out of whey protein. It has excellent digestibility and contains a high proportion of essential amino acids. Branched‑chain amino acids (BCAAs ) are a natural part of it and contribute to the growth and maintenance of muscle mass.

*The most up‑to‑date indicator of protein quality based on essential amino acid content and protein digestibility. Proteins with DIAAS >75% are rated as high quality, >100% are excellent protein sources according to FAO.
Natural colour and flavour
Authentic and all‑natural flavour from real ingredients such as cocoa and freeze‑dried fruit. No synthetic flavours and colours used to manipulate the taste and mask inferior ingredients.
Pleasantly sweet taste thanks to a sweetener from stevia leaves
The stevia plant allows us to produce a high‑value sweetener containing steviol glycosides. These have no effect on blood sugar levels, are 200‑300 times sweeter than sugar itself and can be considered a safe non‑caloric sweetener of natural origin.
Why does our protein not contain sucralose? Sucralose is a synthetic compound of chlorine and sucrose. It is currently the most widely used artificial sweetener. However, several studies have recently emerged that point to a possible negative effect on insulin sensitivity, even at doses commonly taken by consumers of dietary supplements. Another potential negative effect of sucralose is on reducing the amount and diversity of gut bacteria in the microbiome, which continues to prove its importance in the overall impact on our health.
| ✔️ Steviol‑glycosides | ❌ Sucralose | |
| Safety | No effect on insulin resistance | Possible negative effect on insulin resistance |
| Origin | Natural origin | Synthetic origin |
| Sweetness | Medium sweetness | High sweetness |
| Microbiome | Does not negatively affect the microbiome | Possible negative effect on the microbiome |
Easily digestible with lower lactose content
Thanks to advanced filtration, our isolate contains only 0,5% lactose. The maximum upper limit is 1% lactose. The protein is therefore gentler on the digestive system.
More protein, less fat and sugar
Isolate offers a higher concentration of quality proteins while keeping fats, sugars, and carbohydrates to a minimum. Each serving provides just 109 kcal.
*Valid for a drink of 30 g protein and 250 ml water.
The best shake after workout and for a diet too
Isolate is absorbed faster than concentrate due to its significantly lower fat and sugar content. This makes it the ideal choice after strength training when you need to replenish your protein stores as quickly as possible.
