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)	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
Working memory in high-stress settings (e.g. military training)	In a strenuous week-long combat training course, cadets receiving tyrosine performed significantly better on a memory test and a tracking task than those on placebo. This suggests tyrosine preserved working memory function under extreme stress in the field.	PubMed

Dosage Recommendation

Goal	Capsules per Day
Acute Stress & Cognitive Performance	4 capsules (2 g total) taken 30–60 minutes before a high-stress task or demanding mental work
General Cognitive Support	2 capsules (1 g total) in the morning on an empty stomach for baseline neurotransmitter support
Mood & Mental Clarity	2 capsules (1 g total) split morning and early afternoon—helps stabilize catecholamine levels
Physical Endurance & Focus	3 capsules (1.5 g) 30 minutes before exercise or prolonged physical activity
Therapeutic Use (e.g., mild depression)	4–6 capsules (2–3 g) daily in divided doses, 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
