L-phenylalanine 500mg - 90 capsules

Essential amino acid with significance for the central nervous system

Phenylalanine is an essential amino acid, which means that the human organism is not able to synthesise it itself. Therefore, it is dependent on the supply through food.
Phenylalanine is able to cross the blood-brain-barrier and is involved in the synthesis of various neurotransmitters such as dopamine, noradrenaline and serotonin, which are crucial for the normal functioning of the nervous system. This way, the amino acid can contribute to our well-being.

Different forms of phenylalanine

There are three different forms of phenylalanine: L-phenylalanine, D-phenylalanine and DL-phenylalanine (the latter is a combination of the other two forms). L-phenylalanine can naturally be found in proteins, whereas D-phenylalanine is produced after model of the natural form.
