Protein of protein powder, like protein supplied by natural food, is decomposed into short peptides and amino acids by various proteases after entering the digestive system. These small molecules enter the blood and are transported to the amino acid metabolism bank of the whole body for storage.

After strenuous exercise, people will cause muscle catabolism. At this time, the body is like a repairman, ready to synthesize muscles. Therefore, the body extracts the required amino acids from the amino acid metabolism library, and the amino acids enter cells, are translated into muscle proteins, and are transformed into muscle tissues in the nucleus. This process increases the mass and volume of body muscle tissue, thus achieving the effect of muscle gain.

Extended data:

Protein powder generally refers to soybean protein extracted from soybeans or whey protein extracted from milk, but more protein powder is made by mixing these extracts and adding appropriate minerals and vitamins.

Soybean protein comes from soybean and is a plant protein. Whey protein is derived from milk extract and belongs to animal protein. Mixed protein is to mix the two in different proportions. But even the best quality protein has some shortcomings, such as the lack of methionine in soybean protein and isoleucine in whey protein. Eating only one of them can't satisfy the body's demand for protein. Several foods need to cooperate with each other and complement each other to maintain the stability and balance of the body. Therefore, the absorption rate of mixed protein products is theoretically the highest.
