An Amino Acid for Stress Management • Required for the synthesis of essential hormones and neurotransmitters • Enhances cognitive function • Improves alertness • Helps with multitasking Brain Signals Tyrosine is an amino acid that is used to produce thyroid hormones and crucial brain signaling molecules such as dopamine and norepinephrine. Acute stress can deplete the brain of these two neurotransmitters. Tyrosine’s control over their production makes it helpful in stressful situations, whether physical or psychological. Supports Cognitive Function Studies have found that tyrosine can enhance brain function and alertness under conditions of stress such as sleep deprivation, high¬altitudes or cold temperatures. By enhancing the numbers and activities of neurons, tyrosine can improve the ability to multitask. In clinical trials, tyrosine supplementation improves accuracy and memory scores, and improves alertness during periods of sleep deprivation. Tyrosine supplementation has also been found to significantly alleviate symptoms of mood and performance induced by conditions of stress, such as alertness and anxiety. For Conditions of Stress Tyrosine is an important amino acid, and is required for the brain to function properly. For those who must often work under conditions of stress, it offers a natural way to enhance the production of brain chemicals that help deal with these conditions. L-Tyrosine is an amino acid and the precursor for the neurotransmitters epinephrine, norepinephrine, and dopamine, which are chemicals that are essential for cognitive and central nervous system function. It is also the precursor of the hormone thyroxine, as well as melanin, the skin and hair pigment. The most prevalent usage for supplemental tyrosine appears to be the enhancement of cognitive function and alertness under conditions of environmental stress. Multi-tasking In the modern workplace, multi-tasking refers to the number of competing tasks and responsibilities that simultaneously require an employee's attention. The proper execution of a diverse battery of tasks requires optimal cognitive flexibility. Neurotransmitters have to send messages from one neuron to another at sufficient speed in order to ensure an effective operation. In an office trial of tyrosine, the amino acid significantly enhanced accuracy and working memory scores. Sleep Deprivation Military life is one of the few areas of employment in modern society where the work is meant to be as physically and as psychologically taxing on its employees as possible. In a study conducted at the U.S. Naval Aerospace Medical Research Laboratory, marine aviators who had been sleep deprived for 24 hours and who took tyrosine scored markedly higher and made significantly fewer errors in their standardized tests which measured their hand-eye coordination, memory capacity, and comprehensive skills than those who did not take tyrosine. High Altitudes and Cold Weather Hypoxia is the condition whereupon the body's tissues are deprived of oxygen. This can take place in high altitudes (due to thin air) and extremely cold temperatures (due to constricting arteries). In animal trials, rats swimming in freezing water had a significantly reduced time to immobilization, so much so that the performance levels of these animals matched those that were not exposed to cold-induced stress. When tested in simulated heights, the decreases in performance among the tyrosine-treated animals were only marginal, while the non-treated animals' decline in performance was considerable. Human studies with tyrosine have been equally impressive. In clinical trials among soldiers operating at mountainous altitudes of 15,300 feet, tyrosine significantly mitigated many of the decrements in symptoms, mood, and performance induced by the altitude, including functions such as vigilance, alertness, and anxiety. Tyrosine was also tested for its effects on acute cardiovascular stress. Using a method designed to simulate gravitational stress, subjects who were given tyrosine experienced stabilized pulse pressures and increased central nervous system activity. ADD ADD or Attention Deficit Disorder can be defined as a persistent pattern of inattention, hyperactivity, and impulsivity, occurring more frequently and severely than is typical in individuals at a comparable level of development. There appears to be some connection between this disorder and the maintenance of adequate levels of certain amino acids, especially phenylalanine, tyrosine, tryptophan, histidine, and isoleucine. While the results from studies conducted with tyrosine with specific regard to ADD have been mixed, there appears to be potential for usage of tyrosine in cases of ADD that are of a transient type. Trying to obtain the benefits of tyrosine from diet alone is not an option, since the foods that are the richest sources of tyrosine, namely turkey and wild foul, are also the richest sources of the amino acid tryptophan, which is notorious for its ability to induce lethargy and sleep. AOR’s Tyrosine provides a safe and effective dose of this important amino acid.
