What is L-Phenylalanine?

L-Phenylalanine is an essential amino acid, which cannot be produced by the human body and must be obtained through diet or supplements. It is a building block of proteins and plays a key role in the production of neurotransmitters such as dopamine, norepinephrine, and epinephrine, which are vital for mood regulation, focus, and brain health.
