ISO-9 Whey Isolate (900 g) by Naughty Boy is a protein powder formulated exclusively from whey protein isolate. It is designed for athletes looking for a whey protein with a high protein concentration and limited carbohydrates, sugars, and fat.
One serving provides up to 26 g of protein for only 108 to 111 kcal, depending on the flavor. Protein helps build and maintain muscle mass, so you canincorporate ISO-9 into your post-workout routine, as a snack, or for breakfast when your diet doesn’t fully meet your daily needs.
ISO-9 Whey Isolate is a triple-filtered, low-lactose whey isolate. This process concentrates the protein fraction while reducing the presence of components naturally found in whey. ISO-9 is therefore a good choice if you prefer a smoother, lighter texture than that of a traditional whey concentrate.
ISO-9 comes in several delicious flavors, ranging from classic favorites like Vanilla Ice Cream, Strawberry Milkshake, and Chocolate Brownie to more original creations like Banoffee Pie, Peanut Butter Blondie, and Mint Cookies & Cream.
