Phenylalanine – An Essential Amino Acid
Protein Building Block for Neurotransmitters Like Dopamine
The amino acid phenylalanine (L-phenylalanine) is essential for humans – the body cannot produce it on its own. Phenylalanine is used to build proteins. Adequate protein intake is not only important for muscles, but also for the production of neurotransmitters and hormones in the nervous system – for example, dopamine.
