AVELOR SUMMARY
L-Tyrosine is the direct precursor to dopamine, norepinephrine, and epinephrine. Most evidence for cognitive performance under STRESS conditions (cold, sleep deprivation, multitasking). 500-2,000mg pre-stressor. NALT (N-Acetyl L-Tyrosine) is better absorbed but less efficiently converted to catecholamines.
