ISO Protein — a fast start, long-lasting recovery
The combination of ultra-pure whey protein isolate and milk protein ensures a rapid supply of amino acids after training and their gradual release over the following hours. The result is support for recovery and muscles, along with an exceptionally creamy taste.
Ultra-pure whey protein isolate provides rapidly available amino acids, while milk protein extends their availability.
How ISO Protein works
Whey protein isolate is pure protein with minimal fat and carbohydrates – a perfect supplement for both low-carbohydrate and regular diets. Its amino acid profile closely matches the needs of the human body, helping to support muscle protein synthesis.
What does the WPI 90 designation mean?+
IWPI 90 is one of the purest forms of whey protein — it contains approximately 90 % protein, while its fat and lactose content is minimal. It is highly soluble, rapidly digestible and has high bioavailability, allowing it to deliver nutrients to the muscles quickly.
Why combine isolate with milk protein?+
WPI is absorbed very quickly and ensures a rapid supply of leucine and other essential amino acids. Milk protein contains casein, which is digested more slowly and releases amino acids gradually. Thanks to this combination, the body receives amino acids immediately after training and throughout the following hours.

What makes ISO Protein exceptional?
Two-phase amino acid supply
The combination of whey protein isolate and milk protein delivers amino acids rapidly and releases them gradually over the following hours.
Naturally rich in leucine
Whey protein isolate is one of the richest sources of leucine — a key amino acid for the formation and recovery of muscle proteins.
The purity of isolate + the benefits of milk protein
Ultra-pure whey protein isolate with minimal fat and lactose is complemented by milk protein containing other naturally occurring milk components. Together, they create a more comprehensive nutritional profile than isolate alone.
Key ingredients of ISO Protein
Who is ISO Protein intended for?
Composition of 1 serving (30 g)
One serving (30 g) contains 24 g of protein, including 2.5 g of leucine, 3.9 g of glutamine and a complete spectrum of essential amino acids.
Why choose ISO Protein?
Two-phase amino acid supply
Rapid absorption of WPI and gradual release from milk protein for immediate and long-lasting muscle support.
Leucine to support protein synthesis
Powerful activation of muscle protein synthesis thanks to one of the richest sources of leucine.
A combination of two high-quality protein sources
Exceptionally high protein content, complemented by minerals and bioactive milk components.
Better utilisation of amino acids
The gradual release of amino acids from milk protein complements the rapid action of whey protein isolate and supports their longer availability to the muscles.
Minimal fat and lactose
WPI 90 whey protein isolate is one of the purest forms of whey protein and is characterised by minimal fat and lactose content.
Premium taste and solubility
WPI provides excellent solubility, while milk protein delivers a fuller, creamier texture — a drink that is exceptional both functionally and sensorially.
Frequently asked questions
How much protein does one serving contain?+
One serving (30 g) contains 24 g of protein, which is equivalent to 80 g of protein per 100 g of product.
When is the best time to take ISO Protein?+
Ideally during or immediately after training, when muscles can make the best use of rapidly available amino acids. One serving per day is recommended.
How do I prepare the drink?+
Mix 2 scoops (30 g) with 200 ml of water or milk, stir well and drink.
How does it differ from regular whey protein?+
ISO Protein combines ultra-pure whey protein isolate with milk protein. This gives you both fast- and slow-release amino acids, a stronger insulin response and greater nutrient density than isolate alone.
Does it contain a lot of sugar or lactose?+
No. One serving contains only 2.6 g of sugars and 0.4 g of fat. Whey protein isolate contains minimal fat and lactose.
Is it suitable when dieting or losing weight?+
Yes. Thanks to its high protein content and low fat content, it is a suitable supplement for both weight-loss and regular diets.
What flavours does ISO Protein come in?+
The limited edition is available in Chococino (with 22% cocoa powder) and Salted Caramel flavours.
Can children take it?+
Children aged 7 to 14: ½ serving (15 g) daily. Not suitable for children under 6 years of age, pregnant women or breastfeeding women.
Does it contain prohibited substances or GMOs?+
No. The product is labelled No doping and No GMO.
How should ISO Protein be stored?+
In a dry place at temperatures up to 25 °C, in a tightly sealed container, out of reach of young children and away from direct sunlight.
