Phenylalanine is an important amino acid, which is also a “building block” of protein in the human body. Phenylalanine is available in three different forms, viz. D-phenylalanine, L-phenylalanine, and DL-phenylalanine. The last one is formulated by the researchers, which is a combination of the previous two phenylalanine. L-phenylalanine is an indispensable amino acid and is the only form of phenylalanine found in the human body. The amino acid has multiple of benefits for the body including some positive effects on the central nervous system.

While doing so, many important and useful chemicals couldn’t reach the brain and nervous system. Phenylalanine is called cognitive enhancement supplement, because by crossing the blood-brain barrier it enhances the capacity of neurotransmitters like dopamine, norepinephrine, and epinephrine, etc. It also aids in the production of melatonin.
Moreover, Phenylalanine also helps in forming tyrosine, which is another important amino acid that helps in controlling several neurological disorders like depression and anxiety. Tyrosine helps in creating several important chemicals in the brain like L-dopa, epinephrine, norepinephrine, etc.
