Key Benefits
- Supports dopamine and norepinephrine production
- Enhances focus under stress
- Supports thyroid hormone synthesis
- May improve cognitive performance
- Buffers effects of acute stress
What is L-Tyrosine?
L-Tyrosine is a non-essential amino acid that serves as a precursor to several important neurotransmitters (dopamine, norepinephrine, epinephrine) and thyroid hormones. While your body can make it from phenylalanine, supplementation can support production during high-demand periods.
Stress Response
Acute stress depletes catecholamine neurotransmitters. Tyrosine supplementation can help maintain cognitive performance during stressful situations—whether physical (cold exposure, sleep deprivation) or mental (demanding tasks).
Cognitive Enhancement
By supporting dopamine synthesis, tyrosine may enhance working memory, mental flexibility, and focus. Effects are most pronounced when catecholamines are depleted.
Thyroid Support
Tyrosine combines with iodine to form thyroid hormones (T3 and T4). Adequate tyrosine intake supports healthy thyroid function.
Forms and Dosage
N-Acetyl L-Tyrosine (NALT) is more soluble but may be less effective than plain L-Tyrosine. Typical doses range from 500-2000 mg, taken on an empty stomach 30-60 minutes before stress or demanding tasks.
