Cyto Tyrosine

Cyto Tyrosine is a conditionally essential amino acid that acts as the building block for cortisol and other important hormones such as dopamine, norepinephrine, epinephrine and thyroxine. As a result, tyrosine is indicated for improving cognition, stress coping and thyroid health.

Research has shown that tyrosine is capable of improving cognition during times of stress. Specifically, a number of studies have examined the stress response of military personnel. Subjects exposed to stressors such as extreme cold and hypoxic environments demonstrate significant improvements in mood and cognition after taking 100mg of tyrosine per kilogram of body weight daily.

At a higher dose of 150mg/kg, improvements in cognition and reduced fatigue after sleep deprivation have been noted. Finally, tyrosine supplementation was also able to acutely reduce blood pressure and improve performance on memory tasks during a week of combat training in cadets. When it comes to thyroid health, daily tyrosine supplementation given to healthy individuals during the winter months in Antarctica has been shown to improve mood, increase free triiodothyronine (T3) and reduce elevated thyroid stimulating hormones (TSH).

Tyrosine has also demonstrated potential benefits in cases of depression, Parkinson’s Disease, attention-deficit disorder (ADD) and narcolepsy.
