is a category of protein supplements also known as WPI (Whey Protein Isolate). They are derived from milk, and boast a highly beneficial amino acid spectrum. They are manufactured by first producing a whey concentrate, which is then used to derive whey isolate via filtration. This makes for a much “cleaner” product, meaning a whey isolate usually boasts a high protein content (80 % and more), while containing a lot less lactose (milk sugar), fats, and generally providing a higher absorbability rate. This kind of ingredients profile is particularly useful for strength athletes on a diet, who are looking for the cleanest possible sources of protein, or suffer from issues that complicate their ability to digest lactose. Products such as Pure IsoWhey or IsoFue are prototypical in this category. And if you enjoy refreshing fruit flavours, you will no doubt love Clear Whey IsoFue.
With whey protein isolate, it is usually recommended to serve about 0.25 - 0.3 g per kg of body weight. If you can’t be bothered with calculating, you won’t go wrong with a serving of about 20 - 40 g of the product. This corresponds to a roughly topped 30 g measuring scoop. The upper limit of 40 g is intended for strength athletes after a full body training, when the body requires extra protein.
