Main highlights

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.
