Protein is made up of chains of amino acids, which are the building blocks of all body tissues. Protein (from food and supplements) is used to form bones, skin, nails, hair, muscles, and cells. Protein also plays a major role in producing all the essential enzymes for the body.
Consuming protein stimulates the body to produce amino acids, build muscles, and inhibit muscle breakdown for long periods. Protein intake increases strength in the gym and speeds up muscle recovery after workouts.
Whey protein contains proteins of higher quality and nutritional value than eggs, milk, and meat. It is also rich in BCAAs (Branched-Chain Amino Acids) like leucine, valine, and isoleucine.
For this reason, whey protein is dedicated to muscle growth and hypertrophy. It also helps maintain muscle mass while following a diet.
