Whey protein isolates (WPI) have a very high protein content, with limited amounts of other nutrients (carbohydrates and fats). This makes them a great source of “clean protein”, especially in the diet of active people.

Whey protein isolates work brilliantly for protein supplementation, because they are easy to digest and are absorbed very well and very quickly. Using WPI appropriately in the form of protein shakes helps to top up any protein shortfalls in the diet and improve muscle mass growth. Depending on when whey protein is taken, different benefits can be achieved. For example, using a protein shake before training helps prevent excessive catabolism, while after training it speeds up muscle recovery and stimulates their growth.
