Whey protein is the supplement of choice for athletes and bodybuilders alike as it includes high levels of branched chain amino acids (BCAAs) which work to create the energy needed to power through your workout. The BCAAs in whey protein are vital for training as these amino acids are metabolised in the muscle instead of in the liver. This means that after taking a whey protein supplement amino acids get to work quickly by supplying energy to your muscles during training. BCAAs are also regarded as essential for the repair and growth of muscles post-workout.
Whey protein has a fast absorption rate, therefore, it is ideal to take first thing in the morning before your workout or straight after your gym session to help recovery.
