UNBEATABLE FORMULA: With 48% essential amino acids and a high proportion of BCAAs, our whey isolate powder delivers an excellent amino acid profile that optimally supports protein synthesis. Bioactive protein components, such as globulins and lactoferrin, help in the targeted absorption of muscle building materials and body's own regeneration.
Protein from pasture milk: the whey proteins of our protein powder are obtained from the milk of pasture cows from Ireland and New Zealand. Pasture milk is particularly rich in linoleic acids and contains a greater proportion of omega-3 fatty acids than milk from stable animals.
Ideal in the morning or after training: the extremely anabolic protein powder is absorbed very quickly and well by the body and causes a positive nitrogen balance for a few hours. The "fast acting" protein is ideal after getting up or training. 100% instantised, the powder dissolves perfectly in water or milk and reaches the muscle cell even faster.
High protein powder: with 96.5% protein i.tr. The protein powder impresses with its extremely high protein content, which is made of high-quality CFM whey isolate with less than 1% fat and carbohydrates per serving. This makes the protein shake perfect for building and maintaining muscle mass.
German production: developed by athletes for athletes, POWERSTAR FOOD relies on the best ingredients. Since 1993, we have been producing dietary supplements and sports nutrition based on the highest quality raw materials in pharmaceutical quality.

Native protein in its purest form: by preserving the whey protein in its native, non-denatured form, Iso Whey Zero offers maximum bioavailability and absorption. This means that your body can use the high-quality protein more efficiently to build and repair muscle, while supporting controlled calorie intake that is essential for achieving fitness goals.
Low lactose, sugar-free and clean formula: Iso Whey Zero contains less lactose and no added sugar and is therefore a clean source of protein. It is also gluten-free, palm oil free and preservative-free, making it a great option for people with dietary sensitivities or special nutritional goals.
Highly modern filtration process: Iso Whey Zero undergoes a unique, multi-stage filtration process at low heat that preserves the integrity of the protein while removing unwanted fats, sugars and bacteria. This process delivers a highly purified protein powder that is not only more effective but also easier to digest, promoting faster recovery and muscle development.
Extracted from the milk of grass-fed cows: our whey protein is derived from the milk of grass-fed cows, which ensures a clean, sustainable and high-quality protein. Grass-fed cows produce milk that is naturally richer in essential nutrients, making them an optimal choice for those looking to support muscle growth and overall well-being.
Enzyme-free technology for purity: unlike many other protein powders, we do not use enzyme treatment to reduce lactose content. Instead, our state-of-the-art filtration technology naturally preserves the purity of the protein and ensures a clean, natural product without unnecessary chemicals or additives.
