L-Theanine - Benefits, Effects, Consumption

L-Theanine - A Food Supplement For Brain Activity And Mood

L-Theanine is a naturally occurring amino acid that has been shown in some studies to help with energy levels and stress.

Its effects have been supported by thousands of years of use in Chinese medicine, as well as the latest scientific and clinical research. (Sources below)

This natural nootrop was originally made from Green Tea in 1949. Since then, he has been studied for his ability to maintain brain health and enhance concentration.

The cognitive effects of L-Theanine are evident when combined with caffeine, or consumed naturally in green tea. Synergy of the two ingredients: Caffeine increases alertness levels, and Theanine can reduce some of the causes of nervousness and anxiety that can occur with stimulants.

Before deciding whether to use L-Theanine, you may be wondering what it is, its published studies, reports on the benefits, how it works, and possible side effects.

 

What Is L-Theanine?

L-theanine (gamma-glutamylethylamide) is an analogue of glutamate and glutamine that can cross the blood-brain barrier.

It is a form of L-glutamic acid that can help increase and modulate alpha brain waves. These brain waves help to produce feelings of calm, relaxation and alertness.

In addition to naturally occurring Camellia Sinensis (green tea), L-Theanine is also found in certain types of mushrooms.

The chemical composition of this substance is similar to that of L-tryptophan. It is a precursor to the neurotransmitter serotonin (which helps influence sleep cycles and feelings of relaxation).

Several studies have confirmed the benefits of Theanine. The first was in 1999. Journal of Food Science and Technology published. The researchers found some interesting facts in people who were given 50 to 200 mg of Theanine a week.

Their brain waves were then measured and it was found that those who received the highest doses of Theanin produced the most alpha brain waves. This allowed them to be more relaxed and still vigilant enough to perform complex tasks.

Animal studies have shown that this supplement causes higher levels of dopamine in the brain. 2004 A study by Harvard Medical School shows that this supplement also acts as a means of strengthening the immune system and helps increase the body's resistance to colds and flu.

Studies have even been done on chemotherapy patients who have taken L-Theanine. These results suggest that the supplement helps focus chemicals on unhealthy cells. It can also help reduce the side effects of chemotherapy due to its calming and relaxing effects, although more research is needed for this use.

 

Food Supplement L-Theanine Benefits

Theanine has many different benefits for mood, cognitive function, and overall health. The main effect is a feeling of relaxation.

L-Theanine is also the reason why green tea is drunk for anxiety and nervousness (unlike coffee), despite the fact that green tea contains caffeine. Theanine actually helps alleviate those caffeine-related side effects, reducing the signs of nervousness or restlessness.

 

How Does L-Theanine Work?

Although the specific mechanisms of action of L-Theanin are not fully understood, this substance has the potential to cross the blood-brain barrier.

It penetrates the blood very quickly and is very fast acting.

Its action begins with the application of various neurotransmitters and their receptors. These include serotonin, dopamine, GABA and noradrenaline.

These are all powerful brain chemicals that have a big impact on cognitive processes, sleep and relaxation cycles, even pleasure and the reward system of the brain.

 

L-Theanine Consumption And Possible Side Effects

There are no known specific side effects associated with this dietary supplement. However, some users have reported diarrhea at high doses of Teanin. Despite the fact that L-Theanine was made with a beverage containing caffeine, such as green tea or coffee, it is the usual way in which people consume this supplement, and the acidity of the drink has actually caused gastrointestinal upset.

This supplement is not recommended in combination with medicines to treat high blood pressure; the combination can actually lower blood pressure too much. Also, do not take Theanine with stimulants as this will probably reduce their effectiveness. It is always recommended to talk to your doctor before starting any new supplements.
