Amino acids are the smallest components in proteins. There are a total of 20 amino acids, nine of which are essential and must be supplemented through our diet. All amino acids have different properties and therefore have different effects on the body. The advantage of dietary supplements with free amino acids is that they can be absorbed relatively quickly by the body, as they do not need to be broken down in the stomach. Different amino acids are best-suited depending on the field of ??use.
