“I’m a shift worker, and sometimes when I am working night shift, I can see that my mental focus is worse than during the day shift. L-tyrosine has really helped me stay awake and to function as normally as I would have if it was a day shift.”– Lito, Ang Mo Kio, Singapore.
L-tyrosine is a type of amino acid that is commonly found in the human diet which is involved in the production of neurotransmitter including adrenaline, noradrenaline and dopamine. This amino acid is broken down to help produce these neurotransmitters, also known as catecholamine. They are essential for brain function, especially beneficial for stress reduction and mental focus.
Other important and key features of L-tyrosine include:
- Improves mental focus and motivation
- Stress reduction
- Helps with mood stabilization
- Regulate appetite
L-tyrosine exhibits the most potent effects on the brain and central nervous system. Being an amino acid that promotes the production of catecholamine neurotransmitters, L-tyrosine has a particularly strong stress reducing effect. This has been believed to be linked to the fact that L-tyrosine is an important component in the productions of the stress hormones, both adrenaline and noradrenaline. What they have found is that L-tyrosine helps to increase the production of these stress hormones, and therefore, enables body to better manage stress. Studies have demonstrated better performance and memory of individual even under stressful circumstances.
Additionally, L-tyrosine also reduces fatigue following sleep deprivation. L-tyrosine is capable in improving mental alertness, reduces mental fatigue as well as increased mental capacity and cognitive functions after prolonged stressful exposure and sleep deprivation.
Dopamine is a neurotransmitter that is widely distributed in the brain. It potentiates its effects mainly in the parts of the brain related to control of movement as well as emotion and drive. As L-tyrosine increases the production of dopamine, it is the main reason for the general mood stabilizing capability. There has been some speculation that L-tyrosine may be effective in combating against depression, although this has yet to be proven in clinical studies. In addition, L-tyrosine involves in hormonal regulation and the role of these hormones eventually lead to healthy weight management through appetite modulation.
