Amino acid preparation with the essential amino acid phenylalanine in its bioidentical L form.

L-phenylalanine is an essential amino acid needed for the production of stimulatory neurotransmitters in the brain, such as dopamine and ß-phenylethylamine (PEA). These neurotransmitters increase attention and mental activity, boost drive and brighten moods. Increased dietary intake of L-phenylalanine is recommended in particular for people with lowered dopamine or PEA values.
