Another type of protein powder which can bring about great gains in one's workout plan is casein. It is the dominant protein found in milk. Roughly eighty percent of cow's milk protein is casein while the remaining twenty percent is whey.
Casein protein is loaded with amino acids but in contrast to whey, it is a slow-digesting protein. Due to this characteristic, it has little effect on protein synthesis. Casein protein forms a lining in the stomach, resulting in a steady stream of amino acids to the bloodstream over time. Consumption will result in a peak in blood amino acids and protein synthesis for up to seven hours. In contrast, whey protein consumption yields the same results in forty minutes.
One of its great benefits is its ability to suppress protein breakdown. What this means is that casein is an incredible muscle-sparing protein. Muscle growth is simply striking a balance between maximising protein synthesis and minimising protein breakdown. Casein makes its presence felt by preserving the muscles.
