PHENYLALANINE – is a precursor of tyrosine, as well as hormones and neurotransmitters such as adrenaline, noradrenaline and dopamine. Since the human body is unable to produce phenylalanine on its own, it belongs to the group of exogenous amino acids and must be obtained from an external source, e.g. from food or supplement. The normal functioning of the neurological system requires the consumption of a certain amount of phenylalanine. On the other hand, it is possible that we have among us a person allergic who suffers from phenylketonuria. In this case, you should absolutely avoid this amino acid in your diet. It has a significant effect on the body. It promotes development, but is also useful for anabolic purposes. Supports attention, affects muscle coordination and sensation.
