Amino acids are nutrients from which all protein tissues of the body are formed. Organs and muscles are almost entirely made up of protein, that is, amino acids. When we consume protein (protein) in the process of digestion, it is broken down into peptides, and from peptides into free amino acids. Only after free amino acids enter the circulatory system are they distributed to organs and tissues in order to repair damaged tissues or create new ones. If the body does not have enough carbohydrates and blood glucose levels begin to drop, amino acids will be used as an alternative source of energy.
The body uses them for its own growth, recovery, strengthening. Not only the increase in strength and “mass” of muscles depends on them, but also the restoration of physical and mental tone after training, as well as the intellectual activity of the brain. It is the fastest building material available to our body that we can provide. It is worth noting that with 23 amino acids involved in the formation of hormones, antibodies, enzymes, structural tissues, only 15 our body is able to produce itself (endogenous amino acids). These amino acids are synthesized in the liver. The remaining 8 are called essential (exogenous amino acids) – our body is not able to create them on its own (these are isoleucine, leucine, valine, lysine, methionine, phenylalanine, threonine, tryptophan, histidine). The presence of these amino acids in the daily diet is mandatory, and we can get them only with food. It is advisable and effective to take amino acids at a time when they are most needed – in the morning, upon waking, before and after training. The most identical protein (in amino acid composition) to a human is found in chicken eggs, meat, fish – that is, proteins of animal origin.
