L-phenylalanine 500mg - 90 capsules

Essential amino acid

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 involved in the synthesis of various neurotransmitters such as dopamine, noradrenaline and serotonin.

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.
