500mg
Working memory under cold exposure
Moderate
Population: Healthy adults undergoing cold stress
Study type: RCT
Dose context: 2000 mg typical (range: 500–2000 mg) • Duration: Acute

Tyrosine supplementation significantly mitigated cold-induced working memory deficits; proposed mechanism via maintenance of brain catecholamine levels during physiological stress.

Citation: Mahoney CR et al. Physiol Behav. 2007;92(4):575–582.•DOI: 10.1016/j.physbeh.2007.05.003•https://pubmed.ncbi.nlm.nih.gov/17585971/
Benefits appear specific to conditions of catecholamine depletion (stress, fatigue, cold).
Cognitive performance under stress / demanding conditions
Low
Population: Healthy adults under stress (cold, sleep loss, cognitive load)
Study type: Rapid evidence assessment / systematic review
Dose context: 2000 mg typical (range: 500–2000 mg) • Duration: Acute

Weak recommendation in favor of tyrosine for cognitive stress — all reviewed studies showed positive effects; benefits most evident under high environmental demands (cold, fatigue, workload), not at rest.

Citation: Attipoe S et al. Mil Med. 2015;180(7):754–765.•DOI: 10.7205/MILMED-D-14-00594•https://pubmed.ncbi.nlm.nih.gov/26126245/
Tyrosine appears ineffective when catecholamine systems are not stressed; benefits are situational.

fatigue reduction
Moderate
Population: patients with chronic fatigue
Study type: RCT
Dose context: 400 mg typical • Duration: 2 months

Siberian ginseng showed potential efficacy in reducing fatigue in patients with moderate fatigue.

Effectiveness was more pronounced in patients with less severe fatigue.
quality of life improvement
Moderate
Population: elderly individuals
Study type: RCT
Dose context: 400 mg typical

Eleuthero improved quality of life in elderly individuals.

stress adaptation
Moderate
Population: general population
Study type: Systematic review
Dose context: 400 mg typical

Eleuthero is recognized as a natural adaptogen that enhances the body's stability against physical stress.

Timing optimizations
L-Tyrosine
60 min pre-workout or pre-stress event
L-Tyrosine benefits are most pronounced under acute stress or sleep deprivation. Tmax ~2h — pre-dose accordingly. (Onset: ~45 min, half-life: ~3h)
Eleuthero (Siberian Ginseng)
Take ~1h before the intended effect window
Reaches peak plasma concentration in ~1h. Half-life ~3h.
