What is L-Theanine?
L- Theanine is a plant derived amino acid. It is a known NDMA receptor antagonist that decreases the availability of glutamate in the brain. We are unable to make this naturally, which means we must get it from outside sources. Theanine has been shown to have relaxing effects on the brain and although it is not a sedative, it is able to leave you feeling extremely calm and grounded. It won't leave you feeling tired and mentally foggy as most sedatives naturally do, such as benzodiazepines and alcohol. This is because L-Theanine metabolism works much differently than sedatives such as benzodiazepines. Several studies have shown that L-Theanine supplementation works extremely well for helping to put someone into a state relaxation and eustress. In fact, studies have shown that L-Theanine supplementation works better than GABA supplementation in regards to calming effects on the central nervous system due to the fact that L- Theanine is much more bioavaible.
Why Take L-Theanine
L-Theanine is a great option as a supplement for anyone who is chronically anxious, hyper or simply feel as if they can never take their foot off of the gas. Due to the neurophysiology L-Theanine is able to produce, this supplement can help you take the edge off and really relax and unwind.
What is L-Tyrosine?
L- Tyrosine is an amino acid that plays a critical role in producing catecholamines such as dopamine and adrenaline. As we are already aware, dopamine and adrenaline play critical roles in mental focus, energy levels, will power, and being able to workout hard for extended periods of time. L-Tyrosine can be thought of as a building block that is necessary to form dopamine and adrenaline. Think of dopamine and adrenaline as peanut butter and L-Tyrosine as peanuts. You cannot make peanut butter without peanuts, just as you cannot make dopamine and adrenaline without L-Tyrosine. Ultimately, L-Tyrosine may be useful in situations where catecholamines can be depleted by simply providing more material to make new catecholamines. This could include situations such as intense mental stressors, intense workouts, cold exposure or training at altitude.
Why Take L-Tyrosine
L-Tyrosine tends to be taken in doses of 500-2000 mg approximately 30-60 minutes before any intense period of work; such as exercise. You should consider taking L-Tyrosine if you workout intensely multiple days per week, write for long periods at a time, or feel you need something to help kick start your energy levels.
