Main Information
NALT is a highly bioavailable form of the amino acid L-Tyrosine, which supports mental performance, focus, and stress resilience by fueling the production of key neurotransmitters like dopamine, norepinephrine, and epinephrine. It’s ideal for high-stress days, cognitive demands, or situations requiring mental stamina.
Scientific Background
L-Tyrosine is a precursor to catecholamines — neurotransmitters responsible for motivation, alertness, and stress response. In its acetylated form (NALT), the compound is thought to be more stable and potentially better absorbed, making it a preferred option in nootropic formulations.Under stress, catecholamine levels can deplete rapidly, leading to brain fog, fatigue, or reduced focus. Supplementing with NALT can help restore these levels, particularly during sleep deprivation, mental fatigue, or demanding performance periods【1】【2】.Studies show Tyrosine supplementation improves cognitive performance in multitasking, cold stress, and military simulations — particularly under exhaustion or pressure.

Usage Instructions
- Take orally, with or without food.
- Best used 30–60 minutes before mentally or physically demanding activity, or during fatigue states.
Dosage Information
- Cognitive support: 300–600 mg per dose, 1–2x per day
- For stress or mental fatigue: 500–1000 mg before stressful tasks or training
- Optional: Stack with caffeine or adaptogens for synergistic resilience
Important Warnings
- Avoid use if taking L-Dopa or MAO inhibitors
- May cause mild nausea in high doses or on empty stomach
- Not recommended late at night — may interfere with sleep in sensitive individuals.
