The Whey It's
Meant to Be

Going Back to Move Forward

Whey protein is everywhere these days. For many, it's as common a protein source as chicken or turkey, thanks to its nutritional benefits. Since it first hit the shelves as a supplement, whey protein has evolved—not only in popularity but also in variety. Today, there’s a wide range of styles and flavors, along with innovative production methods that have brought us isolates and hydrolysates with higher protein concentrations.

But does this mean that "bigger and stronger" is the only direction for whey protein products? Our Pure Native Whey Isolate challenges that notion. Sure, it delivers the purity, mixability, and flavors you expect, but there's one key difference. As paradoxical as it sounds, we've made progress by going back to the source.

The Whey to gain

Protein is an essential nutrient, playing a critical role in building and maintaining muscle mass. The quality of the protein you consume makes all the difference. So, what could be better for your muscles than pure, high-quality protein?

Back to the source

Comes directly from milk

Cheese derivative

Pure Native Whey

Regular Whey

Whey protein comes from milk, but how it's extracted makes all the difference. Our Pure Native Whey Isolate is unique—it’s made from native whey, not sweet whey, which is a byproduct of cheese-making.

Unlike sweet whey, native whey isn’t exposed to enzymes, starter cultures, or acids during the cheese curdling process, which means it remains free from non-native elements like glycomacropeptides and typically contains lower levels of lactic acid.

Top-Quality Raw Material

Whey protein starts with milk, and we use only the best—sourced from healthy cows. At Prozis, we prioritize quality by selecting milk from trusted farms to ensure the best for you.

Pasteurization

To keep things safe, raw milk goes through pasteurization, where it’s quickly heated to kill harmful bacteria without losing its natural goodness. Unlike sterilization, this process keeps the milk’s pure, fresh qualities intact.

Filtration and dehydration

Transforming whey into protein means removing most of the lactose and fat. For our Pure Native Whey Isolate, we use advanced micro- and ultrafiltration to preserve the protein’s integrity, along with key elements like immunoglobulins and lactoferrin. Then, we concentrate, refine, and spray-dry the whey into a fine powder.

Pure Native Whey Isolate

The result? A high-quality protein powder that helps you hit your protein goals with ease. Packed with pure protein, minimal fat, and lactose, plus a touch of flavor and an emulsifier for smooth mixing and great taste, this formula is an easy and delicious way to fuel your day.

The Bottom line

What sets Pure Native Whey Isolate apart is its unique approach. Unlike other products that rely on byproducts from cheese production, we focus on the purest extraction method straight from raw materials. This innovation isn’t just about protein—it’s about delivering clean, natural flavor too. Free from artificial flavors and sweeteners like aspartame or sucralose, Prozis whey is naturally sweetened with stevia extract.

The result? A high-quality protein with minimal sugar and fat, perfect for anyone who wants pure, effective nutrition without unnecessary additives. Try it for yourself, and we’re confident you’ll feel the difference.

Endless Whey to Enjoy

Prozis whey protein isn’t just for shakes. Get creative! Mix it into cakes, muffins, hot dishes, cookies, or bread—the possibilities are limitless.

Very low in sugar, easy to absorb, mixes well, excellent digestion, very good quality, I recommend it

Rohat M.

Tasty, high in protein, and low in calories.

This whey provides everything you need for a cutting phase: an excellent protein-to-calorie ratio, a good, not-too-sweet taste, and no digestive issues because it's native whey. Don't hesitate!

Super Whey

I hear that many native whey proteins don't dissolve properly in water. This one tastes good, it's not sweet, and I never get tired of it, whereas before many whey proteins made me feel sick.

Super high-quality whey! The chocolate and vanilla flavor is amazing, not at all artificial. It dissolves perfectly and is fantastic as a snack or at breakfast.

Whey super

For the past few months, we've been adding whey protein to our morning snack. It mixes in smoothly without lumps and tastes great. Plus, we're over 60, our skin is noticeably firmer, and our muscles are nourished. We couldn't live without it.

Robin G.

One of the best on the market

First, the taste is amazing. Second, it dissolves perfectly. But what I appreciate most is that it's native whey isolate! Extracted directly from milk. It's so important to know what you're eating! And the other essential for me: it's sweetened with stevia! Perfect!
