Diet Whey Protein Isolate 90 from The Protein Works is the highest quality whey protein isolate available anywhere in Europe. Incredibly low in fat, lactose and sugar, it is a welcome addition to any diet plan. Diet Whey Protein Isolate 90 only uses the finest grade ingredients and represents incredible value for money. What this means is your body is given a premium-grade source of protein with only a fraction of the calories, carbohydrates and fats of most other proteins on the market. Our whey protein isolate powder is undenatured and instantised which means the whey is micro-filtered and NOT heat treated. This process ensures that the protein stays intact and as pure as it can be. Just like Mother Nature intended. It also enables the powder to mix easily and achieve a smooth texture, giving you the perfect protein isolate shake.
