L-Tyrosine, Supports cognitive health stress & fatigue 120 veg Capsules
Key Health Benefits
| Use Case | Summary | PubMed Link |
|---|---|---|
| Cognitive performance under stress | Under cold-induced stress, tyrosine supplementation prevented significant declines in cognitive performance. In placebo conditions, working memory accuracy dropped ~18% and marksmanship scores ~14%, whereas tyrosine kept performance near baseline levels. | PubMed |
| Stress biomarker modulation (e.g. cortisol, blood pressure) & Working memory in high-stress settings (e.g. military training) | During intense military combat training, tyrosine supplementation attenuated physiological stress responses. Cadets given tyrosine showed lower stress-elevated systolic blood pressure and maintained better cognitive performance compared to placebo. | PubMed |
| Mental task performance & blood pressure | In healthy adults performing mental tasks under loud noise stress, tyrosine improved performance on stress-sensitive cognitive tasks and transiently reduced diastolic blood pressure (15 minutes post-dose) relative to placebo. | PubMed |
| Cognitive flexibility (proactive/reactive control) | Tyrosine (2 g) significantly enhanced cognitive flexibility during a task-switching test. Participants receiving tyrosine showed reduced task-switching costs (faster, more efficient switching between tasks) compared to placebo. | PubMed |
Dosage Recommendation
| Goal | Capsules per Day |
|---|---|
| Acute Stress & Cognitive Performance | 1 capsule taken 30–60 minutes before a high-stress task or demanding mental work |
| General Cognitive Support | 1 capsule in the morning on an empty stomach for baseline neurotransmitter support |
| Mood & Mental Clarity | 1 capsule with a meal |
| Physical Endurance & Focus | 1 capsule 30 minutes before exercise or prolonged physical activity |
| Therapeutic Use (e.g., mild depression) | 1 capsule daily, under healthcare supervision |

When Will I See Results?
| Outcome | Timeline |
|---|---|
| Acute Cognitive Boost | 30–60 minutes post-dose for improved alertness and working memory under stress |
| Stress Resilience | Noticeable in a single challenge, with optimal effect seen when dosed consistently pre-stress |
| Baseline Cognitive Enhancement | 1–2 weeks of daily use for improvements in concentration, processing speed, and mental clarity |
| Mood & Mental Clarity | 2–4 weeks for more stable mood and reduced brain fog, especially if low tyrosine was contributory |
| Physical Focus & Endurance | 1 week of regular pre-workout dosing for enhanced focus and reduced perceived exertion |
How to Maximize Results
| Goal | Synergistic Stack & Habits |
|---|---|
| Tyrosine Conversion | Take with Vitamin B6 and Folate (B9) to support the enzymes (AADC, BH₄-dependent) that convert tyrosine into neurotransmitters |
| Dopamine Support | Combine with Mucuna pruriens (L-DOPA source) and rhodiola for additive effects on dopamine and catecholamine balance |
| Stress Buffering | Pair with phosphatidylserine and magnesium glycinate to further modulate cortisol and support relaxation under pressure |
| Physical Performance | Stack with caffeine (100–200 mg) and beta-alanine for synergistic improvements in focus and fatigue resistance |
| General Wellness | Maintain adequate protein throughout the day (to supply phenylalanine) and practice stress-management (deep breathing, meditation) |
What to Avoid
| Substance / Condition | Why to Avoid | Advice |
|---|---|---|
| High-Protein Meals | Compete for absorption via same transporters (large neutral amino acid carrier) | Take tyrosine on an empty stomach or at least 1 hour before/after high-protein food |
| MAO Inhibitor Medications | Risk of excessive catecholamine accumulation (hypertensive crisis) | Do not combine without medical supervision |
| Thyroid Hormones | May exacerbate hyperthyroid symptoms when combined | Monitor closely if you use T₃/T₄ therapy; consult your physician |
| Stimulant Overuse (e.g., high-dose caffeine) | Can lead to jitteriness, elevated blood pressure | Limit total stimulant intake; balance with tyrosine dosing |
| Phenylketonuria (PKU) | Tyrosine metabolism is impaired | Contraindicated in PKU; avoid unless directed by a specialist |
