Amino Z L-Tyrosine
What is L-Tyrosine? And more importantly, should you be taking it?
L-Tyrosine is the supplement form of “Tyrosine”.
Tyrosine is one of the twenty amino acids your body needs to function effectively. This particular amino acid is markedly different from many others because it is actually produced in your body using another amino acid called “phenylalanine”.
Beyond being made in your body, Tyrosine can also be obtained in food, where it is found in cheese, dairy products, chicken, fish, and turkey.
The reason tyrosine is particularly important is because it helps your body make a number of very important substances, including :
• The neurotransmitter dopamine, which regulates your mood and wellbeing, while also playing a role in the consolidation or memory and motor skills.
• The hormones adrenaline and noradrenaline, which control your “fight-or-flight” response (which occurs in response to stressful situations).
• Your thyroid hormones, which regulate your metabolism (i.e. how much energy you burn at rest).
With all this in mind, supplementing with L-Tyrosine can cause a subsequent increase in these compounds, which is where it derives many of its benefits.
And talk about the benefits, there are plenty...
Improved Mental Performance
Given the importance of Tyrosine with respect to neurotransmitters and hormones, it should come as no surprise that its supplementation can boost mental performance -- however, this appears to be particularly impressive during times of stress.
Everyone experiences some sort of stress on a daily basis. This stress can decrease neurotransmitter production, which can further impact upon your ability to reason, as well as inhibit your memory, knowledge, and problem solving abilities.
But research has shown that L-tyrosine supplementation can reverse these negative effects by increasing both cognitive flexibility and working memory (two very important mental skills) in healthy adults.
It has also shown to be effective during both mentally demanding situations (i.e. tests and exams) and in times of sleep deprivation -- suggesting it to be one of the most potent mental boosters on the market [1, 2].
Mood and Wellbeing
In addition to cognitive performance, it also appears that L-Tyrosine supplements can improve mood and emotional wellbeing.
It is well accepted that mood can be impacted by the level of neurotransmitters in your brain. To put it simply, evidence would suggest that emotional disorders (such as depression and anxiety) are partially driven by neurotransmitter imbalances.
This is actually how different types of antidepressant medication work -- they attempt to balance out your neurotransmitters.
With this in mind, L-tyrosine is believed to improve mood and emotional wellbeing by increasing the production of key neurotransmitters in your brain . While it is unlikely to be strong enough to help treat depression, it can improve how you feel on a daily basis.
Thyroid Hormone Balance
As we alluded to above, Tyrosine is also important when it comes to the production of your thyroid hormones.
Recent research has shown that supplementing with higher doses of L-tyrosine (12 grams per day) can increase “T3” which is the most active thyroid hormone. Within this, it also appears to lower another hormone called “TSH”, which can be linked to hypothyroidism .
While more evidence is needed, this suggests that L-tyrosine may have the ability to help regulate your metabolism, which can be very important when it comes to weight management and general health.
Boost Endurance Performance
Lastly, the supplementation of L-Tyrosine has also been shown to improve endurance exercise performance in hot conditions.
In an interesting study, athletes were either given an L-Tyrosine supplement or a placebo before conducting an intense endurance exercise test in extreme heat. As you may have guessed, those who got the L-Tyrosine performed about 15% better than the placebo group.
The cool thing here is that the authors believe this may not be due to any changes in physical factors, but rather a psychological improvement in the ability to tolerate hard work .
With this in mind, it could seriously improve your ability to push through the most gruelling of workouts, boosting your results in the process.
It should be apparent that L-Tyrosine supplements can offer some unique benefits when it comes to mental and physical performance, emotional wellbeing, and even mental health -- but how much should you take?
Most people recommend taking between 500 and 2000mg of L-Tyrosine about 45 minutes before the desired activity you are trying to improve (i.e. a gym session, a study session, or even a test).
However, most of the research exploring the applications of L-Tyrosine uses a dosage between 100 and 150mg per kg of body weight taken 60 minutes before exercise.
This means that for someone who weighs 75 kgs, we are looking at taking approximately 7500-1100mg of L-tyrosine, which is much higher than what most people would normally recommend.
Obviously with this in mind, we would suggest you start somewhere between 500 and 2000mg per day before trialling higher dosages -- and of course, seek advice from a medical professional before commencing supplementation.
If you are after a high quality supplement that boosts gym performance, improves focus, and enhances emotional wellbeing and mood, then look no further because we have got you covered.
More importantly, we give you nothing but straight L-tyrosine which means you can adjust your dosage to your own body weight.
