NOW Foods L-Tyrosine Powder provides pure L-Tyrosine in a versatile powder form for easy customization of dosing and convenient mixing into beverages and smoothies. L-Tyrosine is a conditionally essential amino acid that serves as the direct precursor to the catecholamine neurotransmitters dopamine, norepinephrine, and epinephrine, which regulate focus, motivation, mood, and the stress response. Supplementation has been shown in research to support cognitive performance and mental resilience under acute stress, sleep deprivation, or extreme cold exposure by replenishing depleted catecholamine stores.
