Athletic Uses:
· Supplements that boost the brain's dopamine concentration are of interest to endurance athletes.
Some research has suggested that tyrosine might have an positive effect at a high temperature.
· At high temperatures athletes tire more quickly, so having more Tyrosine available may reduce
feelings of tiredness
· Dopamine is the neurotransmitter that motivates people to continue and suppresses feelings of
fatigue and is activated at high temperatures
Cognitive function
· A 2007 study of 19 people (published in Physiology & Behavior) found that use of tyrosine
supplements helped protect against the detrimental effects of severe cold exposure on cognitive
performance and memory.
Depression and mood disorders
· L Tyrosine is an amino acid precursor of the neurotransmitters norepinephrine and dopamine.
Taking tyrosine on an empty stomach causes an increase in norepinephrine and dopamine in the
brain, which can lead to increased energy, alertness and improved moods, thus relieving depression.
· Unlike St John's wort, that can take two months to work, and prescription antidepressants, which
may not work for about six weeks, tyrosine works very quickly.
· Improving Thyroid function can be a useful adjunct in the treatment of depression. As a precursor of
the thyroid hormones thyroxine and triidothyronine, L tyrosine can help to elevate mood and
promote well-being that is hindered by low thyroid
Addictions:
· Brain reward Cascaded pathways are governed by Serotonin, GABA and dopamine.
· Dopamine is a modulating neurotransmitter synthesized in the brain as a monoamine and in the
adrenal medulla as a catecholamine which governs positive reinforcement and reward, addiction,
focus and mood. Disruptions occur when dopamine, noradrenaline or serotonin are imbalanced or
insufficient in the synaptic cleft due to impaired neurotransmitter release.
