ActivLab EAA Xtra 500 g.

The composition is mainly based on egzogenic amino acids (EAA; L-leucine, L-lysine, L-valine, L-isoleucine, L-threonine, L-phenylalanine + L-tyrosine, L-histidine, L-cysteine + L-methionine, L-tryptophan), which due to the fact that the human body is unable to produce them itself, have to be absolutely supplied from outside in food or in the form of a food supplement. If any of these essential compounds is missing, it becomes a factor limiting the protein synthesis in the body in this way disrupting the muscle regeneration process, intensifying the catabolism and having a negative impact on a number of metabolic pathways, in which the egzogenic amino acids are used as direct or indirect substrates.
