L-Theanine is a natural amino acid that comes from components of Green Tea, that are believed to increase energy levels, improve mood, increase focus, reduce anxiety and stress and it is also a mild sleep aid.
What is L-Theanine?
L-theanine (gamma-glutamylethylamide) is an amino acid that comes from the components of green tea and is thought to offer a relaxing peaceful feeling without drowsiness and to improve cognitive functions and mood.
It is also isolated from an edible mushroom called Boletus badius, which is found in the United States and grows in late summer.
This component was discovered in 1949 and was later extracted into a Nootropic supplement for it’s potential cognitive benefits for overall brain health.
The benefits of L-theanine have been used for thousands of years in Chinese medicines. It was originally approved in Japan in 1964 for unlimited use in all foods as an additive to provide a savory flavor.
Today, there has been many extensive and scientific clinical studies on L-theanine’s effects on brain support and focus enhancement.
In the USA, it is generally recognized as safe (GRAS) by the FDA and it is a legal dietary supplement.
The main benefits of this amino acid, promotes the ability to reduce stress, improve sleep, boost focus and concentration and increase alertness.
L-theanine’s chemical structure is similar to glutamate, a neurotransmitter that sends signals between the neurons to reach the brain.
L-Glutamic acid increases and modifies brain waves that produce relaxation. Many people can refer to this feeling as similar to drinking green tea, where you are alert but calm.
Strangely enough, L-theanine is extracted from a tea but seems to eliminate the negative actions of caffeine such as anxiousness and restlessness.
L-theanine also stimulates certain neurotransmitters that enhance clarity and focus while reducing anxiety and stress. This naturally put people in a better mood.
Although, how it fully works is not understood, it seems to target neurotransmitters such as Dopamine, Serotonin, GABA and Norepinephrine which are chemicals in the brain responsible for moods, motivation, reduced anxiety, sleeping patterns, pleasure and many cognitive functions.
Also, L-theanine may protect and support the brain from damage due to low levels of oxygen to the brain.
L-theanine has also shown to provide improvements in cardiovascular health, opening up blood vessels and reducing blood pressure.
Also, some people use L-Theanine to prevent Alzheimer’s and increase the effect of cancer drugs. However, research needs to provide more evidence to back these claims.
Finally, L-theanine is often used in a stack (alongside) with a stimulant Nootropic such as caffeine. Many users have reported that these two taken together increased alertness while it reduced the nervousness that is common with stimulants such as caffeine.
The caffeine helps you focus while the L-theanine keeps you calm and also helps improve your memory. Taking pure L-theanine will also reduce the anxiousness caused by caffeine.
