Focus DL delivers DL-phenylalanine‚ allowing practitioners to fine-tune therapeutic regimens. DL-phenylalanine is the precursor to a number of neurotransmitters‚ including PEA‚ dopamine‚ norepinephrine‚ and epinephrine. Recommended to support focus‚ memory and metabolic maintenance.
DL-phenylalanine: Precursor to phenylethylamine (PEA), dopamine, norepinephrine, and epinephrine (1). PEA is a neuromodulator shown to increase the release of catecholamines such as dopamine and norepinephrine (2).* Dopamine and norepinephrine play an important role in attention and cognition (3).* PEA levels were found to be significantly lower in individuals with focus issues compared to controls (4).
