Benefits of Whey Protein


Whey protein is one of the most used food supplements by those who usually practice a sport. This substance is composed of 20% of the proteins that milk has and is obtained during the elaboration of cheese, being the result of separating it from another protein called casein, which constitutes 80% of the remaining proteins of milk.
