L-Theaninen is a non-protein amino acid that is commonly found in tea leaves, particularly in green tea. It is known for its ability to promote relaxation, reduce stress and anxiety, improve sleep quality, and enhance cognitive performance. L-Theaninen is believed to work by increasing alpha brain wave activity, which is associated with a state of relaxation and alertness. It is also known to increase levels of the neurotransmitter GABA in the brain, which can have a calming effect. L-Theaninen is available as a dietary supplement and is commonly used as a natural remedy for stress and anxiety.


Main Function

Stress and Anxiety Relief:

L-Theaninen is commonly used as a natural remedy for stress and anxiety. It achieves this by increasing alpha brain wave activity and levels of GABA, a neurotransmitter that has a calming effect on the brain. This can result in feelings of calmness, improved focus, and reduced stress levels. It can promote relaxation and reduce stress levels without causing drowsiness or other side effects commonly associated with prescription anti-anxiety medications.

Improve memory, concentration and focus:

In addition to its anxiolytic properties, L-Theaninen has also been shown to have cognitive-enhancing effects, such as improved attention and memory. It is believed to achieve this by increasing the production of certain neurotransmitters, such as dopamine and serotonin, that are involved in mood regulation and cognitive function.

Sleep Aid:

L-Theaninen can help promote relaxation and improve sleep quality. It is often used as a natural sleep aid, particularly for people who have trouble falling asleep or staying asleep.

Sports Performance:

L-Theaninen has been shown to improve physical performance and reduce fatigue during exercise. It may also help improve endurance and reaction time.

Cardiovascular benefits:

L-Theaninen may also have cardiovascular benefits, such as lowering blood pressure and reducing the risk of stroke and heart disease. It has also been shown to have antioxidant properties, which may help protect the body against damage from free radicals.

How Long for L-Theanine to Work?

We understand that when you invest in a brain health product, you want to experience its benefits as soon as possible. While individual results may vary, many users report experiencing the effects of L-Theanine within 30 minutes to one hour after consumption. This makes it an ideal supplement for those seeking quick relief from stress, anxiety, and a lack of focus.
