L-Tyrosine
amino acid for focus under pressure
Administration
Categories
Also Known As
4-hydroxyphenylalanine, N-Acetyl L-Tyrosine (NALT)
Overview
L-Tyrosine is a non-essential amino acid that serves as a critical building block for several important neurotransmitters, including dopamine, norepinephrine, and epinephrine. It is highly valued as a situational nootropic. Rather than providing a baseline boost, L-Tyrosine replenishes depleted neurotransmitters during periods of acute stress, cold exposure, or sleep deprivation, keeping cognitive function sharp.
Safety & Considerations
Should be avoided by individuals taking MAOIs or those with hyperthyroidism, as it can increase thyroid hormone levels.
Always consult a healthcare professional. This information is for educational purposes only.
Benefits
- Maintains cognitive function during physical or mental stress
- Replenishes dopamine levels to prevent burnout
- Enhances working memory during multitasking
- Supports thyroid hormone production
- Reduces cognitive decline from sleep deprivation
How It Works
L-Tyrosine crosses the blood-brain barrier and is converted into L-DOPA via the enzyme tyrosine hydroxylase. L-DOPA is then converted into dopamine, and subsequently into norepinephrine and epinephrine, preventing the depletion of these catecholamines during stress.
Common Uses
- Pre-workout mental focus
- Studying under tight deadlines
- Recovery from acute sleep loss
- Cold exposure therapy support
Typical Protocol
500mg-2,000mg taken 30-60 minutes before an acute stressor, preferably on an empty stomach.
