Tyrosine - Potential Nootropic Benefits
Tyrosine is an amino acid made from phenylalanine and used in the synthesis of proteins. As a nootropic, it is valued for countering stress with healthy brain chemistry for alertness and peak mental performance. Within the brain, L-Tyrosine supports:
1. Neurotransmitter production. The body uses tyrosine to produce norepinephrine, dopamine, and epinephrine.
2. Healthy stress responses. Tyrosine suppresses production of stress hormones and restores brain chemicals that are depleted by stress.
3. Overall mental performance. Tyrosine supports cognition, mood and memory, especially during sleep deprivation and exposure to environmental stressors.
Possible Mental Performance Benefits: Testing has shown tyrosine seems to activate and enhance cognitive performance, including within the brain’s “attention circuitry.” Researchers have also suggested that supplementing with the catecholamine precursor tyrosine “may increase responsiveness to stress,” a benefit supported by research demonstrating that tyrosine helps cognition & memory under taxing conditions.
Beyond nootropic mental performance benefits, tyrosine’s catecholamine support may also hold promise for ADD/ADHD, both of which have been linked to low brain catecholamine levels. In fact, drugs for these conditions work in similar pathways as tyrosine, sharpening attention by producing large spikes in brain catecholamine levels.
L-Tyrosine is a Nootropic for Stress: Stress is notorious for depleting the catecholamine brain chemicals that are critical for sharp mental performance. This is because stress spurs the catecholamine system into overdrive, causing it to “burn through” its catecholamines — especially norepinephrine and dopamine — faster. Stress also depletes the body’s natural tyrosine stores.
These factors may form a vicious cycle, since stressful situations demand sharp cognition, but also deplete the brain chemicals that enable peak mental performance.
If you don’t have enough catecholamine neurotransmitters, cognitive consequences may include “brain fog”, mental fatigue, stress and memory problems.
Researchers suggested that supplemental tyrosine might help because it “can exert acute effects on catecholamine systems within and outside the brain.”
