NeuroScience Focus DL Contains the precursor to PEA, a neuromodulator important for optimal focus, cognition, and catecholamine activity. The Science: Catecholamines 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 Ingredients Serving Size: 2 Capsules Amount/Serving DL-phenylalanine 1 g Other Ingredients: Microcrystalline cellulose, vegetable capsule (hypromellose, water), and magnesium stearate (vegetable source). Phenylketonurics: Contains phenylalanine. Suggested Use Take 1-2 capsules one to two times daily or as directed by your healthcare provider. Do not exceed the suggested use. Warning: If you are pregnant or nursing, consult your healthcare provider before use. Keep out of reach of children. Storage: This product has a tamper-evident seal under the cap. Do not use if the seal is broken or missing. Store at room temperature, in a dry place. More Info. PEA as a neuromodulator Trace amines, like PEA, are similar in structure to neurotransmitters and are involved in the regulation of catecholamines. As no individual neurons exclusively utilize PEA, it is considered a neuromodulator2 The trace amine-associated receptor (TAAR) functions to inhibit the reuptake of the catecholamines 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 symptoms A cohort study of pediatric subjects with focus concerns had significantly lower PEA levels when compared to the control group (p
