Protein shakes were initially consumed by athletes and gym enthusiasts who wanted to increase their muscle mass and improve their performance. In fact, combining protein shakes with resistance training may promote muscle growth and enhance physical performance and recovery.

This happens because resistance training stimulates muscle protein synthesis, as does an increased intake of high-quality protein. As mentioned before, protein shakes provide amino acids that are easily absorbed by your body. Researchers believe that their intake increases amino acid levels in the bloodstream, which in turn triggers a more significant response for muscle synthesis.
