EAA, or exogenous amino acids recognized as essential for life. They can be delivered to the body only with food. Most of them can be found in animal proteins. Plant proteins are also not worthless, but contain fewer amino acids. The EAA includes tryptophan, threonine, phenylalanine, methionine, lysine, valine, leucine, isoleucine and histidine. Plant proteins contain less leucine, lysine, methionine.
The human body is not able to synthesize them in the right amount, which is why they must be supplied from the outside. Supplementing them is especially important during the period of intensive growth and development. Supplementing deficiency is also of great importance during illness.
EAA are very important for the proper development of muscle mass. The lack of even one of these amino acids can lead to inhibition of growth processes and the construction of muscles will be impossible. They have positive effect on the cortisol level, which is released during long physical exertion. EAA are amino acids that take part in anabolic and catabolic processes in the body. Their operation is comprehensive, because the nutrients available on the market provide us with all the necessary exogenous substances, thanks to which our muscles will function properly.
They occur in eggs, fish and meat. If we are unable to provide them naturally with food, it is worth thinking about supplementation. Amino acid supplementation is important in all stages of training, both during the reduction of body fat as well as muscle building.
