Focus DL 

The Science

Focus DL by NeuroScience Inc. contains the precursor to PEA, a neuromodulator important for attention and cognition. A class of neurotransmitters responsible for many functions in the nervous and endocrine systems. „Catecholamines play an important role in mood, energy, memory, attention, and cognition. 



  • PEA

PEA as a neuromodulator 

Trace amines, like PEA, are similar in structure to neurotransmitters and are involved in the regulation of dopamine, norepinephrine, and serotonin. 

  • „As no individual neurons exclusively utilize PEA, it is consider as a neuro-modulator.
  • „The trace amine associated receptor (TAAR) functions to inhibit the re-uptake of the catecholamines dopamine and norepinephrine in vitro.
  • Activation of TAAR by PEA allows these neurotransmitters to remain in the synapse, leading to increased concentrations of catecholamines.

Catecholamines from the prefrontal cortex control multiple cognitive functions including attention, impulse control, and memory.

The science behind the symptoms

A cohort study of pediatric subjects with focus concerns had significantly lower PEA levels when compared to the control group (p<0.05). 

  • „There was a 73% difference in urinary PEA levels in the control subjects when compared to the group with focus issues. 
  • Another double-blind study showed that daily use of 200mg of DL-phenylalanine for 30 days may improve mood.
  • PEA is converted into the metabolite phenylacetic acid, a compound with similar natural effects to that of endorphins.

Focus DL contains amounts of DL-phenylalanine per serving that meet and exceed those used in this study. Looking for ingredients for energy and cognition?

  1. Wesley

    Though I don’t typically believe in 5 star ratings, these products certainly deserve at least 4.5 stars! I have personally used them for over 12 years and absolutely love them! HPA axis Neuro/Endo testing has become a mainstay in establishing baseline neurotransmitter and hormone values while enabling our health coaches to implement neurotransmitter modulation protocols for all of our clients. I highly recommend taking your health and wellness to the next level while incorporating testing into your program.
