Whey protein powder is a precious protein which is separated and extracted from milk by advanced technology. It is called "the king of egg white" because of its high purity, high absorption rate and the most reasonable amino acid composition.
Whey protein is excreted from the stomach and absorbed in the blood faster than other protein powders. Because whey can be digested quickly, it is also called "fast protein", so it is the first choice to be a protein powder with rapid muscle recovery. Moreover, whey protein contains especially high concentration of branched-chain amino acids, and the metabolism of valine, isoleucine and leucine is the most remarkable in the process of high-speed exercise.
Extended data:
Nitrogen is contained in protein powder. When the body ingests nitrogen-containing protein powder, the blood will contain nitrogen. After muscle training, it will be congested, which will help protein to absorb. That is to say, nitrogen protein is more conducive to muscle growth than ordinary protein powder. For ordinary bodybuilders, it is best to use nitrogen protein powder in the later stage, because when the training reaches the bottleneck and the nitrogen effect is not great, and you want to grow muscles, you have to use unnatural bodybuilding supplements. It is best to watch the athletes train for several years.
