Effect of tyrosine supplementation on clinical and healthy populations under stress or cognitive demands: A review
Journal of Psychiatric Research (2015) · Review
Converging evidence for cognitive enhancement under demanding conditions
Based on 8-week RCT showing dose-dependent increases of 22%, 51%, and 142% at 100, 300, and 1000mg respectively. Individual response varies significantly (30% show variable response). NR-SAFE trial confirmed safety up to 2000mg.
Based on single meta-analysis of 56 participants showing significantly higher blood tyrosine concentrations with supplementation. Clinical significance of elevated blood tyrosine levels for cognitive outcomes remains unclear. Most claimed cognitive effects lack direct study support in the provided evidence.
