L-Theanine: Shopping Guide
To help you understand everything about L-Theanine, we have created this Shopping Guide. Check it out.
What is L-Theanine?
In addition, L-theanine also reduces beta wave activity associated with nervousness and hyperactivity. Therefore, L-theanine is known to be effective in fighting stress and anxiety. But the main feature of L-theanine is actually to relax, but without the sedative effect.
What is L-Theanine used for and what are its benefits?
As it acts directly on the nervous system, it triggers the following responses in the brain:
- It affects the alpha waves associated with wakefulness and relaxation.
- It increases levels of dopamine, the neurotransmitter that acts on emotions, mood and attention.
- In some cases it can increase levels of serotonin, the 'happiness' neurotransmitter responsible for improving positive moods.
- When combined with caffeine, it improves memory and reaction time.
Protects the Central Nervous System
Studies indicate that L-Theanine may also protect the brain. Protecting the cells of the Central Nervous System may have an important effect on diseases such as Alzheimer's disease.
With L-theanine the body and mind are calmed, but the symptom of drowsiness does not occur. In other words, L-theanine is not responsible for inducing sleep. However, precisely because it induces relaxation, it is capable of acting on the quality of your sleep.
Research indicates that pre-sleep relaxation is extremely effective against insomnia, for example. No wonder L-theanine is prescribed by doctors as an alternative to improve hours of sleep.
Protects the liver
L-theanine is also known to act on the liver. Studies have shown that consumption of L-theanine was able to reduce blood alcohol levels and reverse alcohol-induced liver damage.
Works on the Cardiovascular System
Because it contains L-theanine, green and black tea are known to stimulate the production of nitric oxide. Nitric oxide dilates blood vessels, increasing the flow of blood. With this, nitric oxide accelerates muscle recovery and the gain of lean mass, strength and endurance. L-theanine appears to promote the formation of nitric oxide having beneficial protective effects on the cardiovascular system.
What is the difference between L-Theanine and other tranquillisers?
L-theanine, on the other hand, promotes instant relaxation. But the main difference between L-theanine and other calming drugs is the fact that theanine has no sedative effect, which allows its use even in situations that require focus and attention, such as when studying or working.
L-Theanine and coffee: Why is this mixture good?
This is because with the use of caffeine, for example, we become alert. But in the end it is possible to feel anxiety and stress effects, which can disturb the quality of your sleep. In some cases, the excessive use of coffee and energy drinks can even cause lack of attention, muscle tremors among other symptoms.
Therefore, the calming effect to L-Theanine reduces the negative effects of caffeine but at the same time, it acts in conjunction with the stimulant promoting focus and retention of information by the brain. However, before ingesting L-Theanine in conjunction with caffeine it is essential that you have medical monitoring.
What is the recommended dose of L-theanine?
Can anyone use L-Theanine?
What are the advantages and disadvantages of L-Theanine?
Not to mention that this amino acid also helps to improve focus, attention and memory, and even has the ability to decrease Pre Menstrual Tension (PMS). On the other hand, the downside is that not everyone can use this substance without medical supervision.
So, in general, check out the table below showing the main advantages and disadvantages of L-theanine.
Purchase Criteria: How to compare L-Theanine supplements
When it comes to choosing the best L-theanine supplement, you need to take some factors that influence not only the price, but the effect you want to have on your health. Therefore, we suggest that you consider the following criteria before buying L-theanine.
From here on we will explain each of these topics in detail.
Tea or supplement
The first factor you should consider before you start taking L-Theanine is how you will do it. As we have seen, L-Theanine comes from tea, particularly green tea. However, according to experts one cup of green tea only has 1% of the recommended daily amount of L-Theanine. Therefore, if you are looking for a better result in reducing anxiety and fatigue, the ideal is to opt for L-Theanine supplements.
Isolated or compound
When it comes to choosing the best L-Theanine supplement, you also need to look at the composition of the product. This is because you can find supplements with L-Theanine both in isolated form and added to other compounds. Not infrequently, you will find supplements that have doses of caffeine, to increase concentration and improve memory. Another option is L-Theanine supplements mixed with passion flower, to boost the relaxation effect.
Another criterion you should check is the dosage recommended by the supplement manufacturer. You can opt for L-theanine supplements whose daily dosage can vary between 50 and 300 mg.
Also consider the amount of capsules that come in the bottle of the L-Theanin supplement. Take into account the period you intend to use it to buy the necessary.
