Whey protein is extracted from the aqueous portion of milk, which is known as whey or milk serum. There are several different whey products in the market which are made with different filtering methods, leading to different degrees of quality and purity, and therefore also different product prices. Proteins fulfill a fundamental role when it comes to the development, repair and maintenance of the tissues occurring in the human body. Faster protein absorption after a training session leads to more efficient muscle recovery, bigger muscle gains and better sports performance. As whey has a very high absorption rate, it is the ideal supplement to take immediately after physical exercise.
