What is L-Theanine?

Research shows the levels of specific brain chemicals may be impacted by l-theanine levels. These include cortisol, which aids the body in managing stress, and serotonin and dopamine, which affect mood, sleep, and emotion. [R]

A person’s mood or level of stress can alter if the balance of these substances changes. [R]

PureRawz sells L-Theanine for research purposes only.

How Does L-Theanine Work?

According to animal neurochemistry research, L-theanine possesses micromolar affinity for AMPA, Kainate, and NMDA receptors and raises brain serotonin, dopamine, and GABA levels. Additionally, it has been demonstrated in animal models to have neuroprotective benefits, maybe as a result of its antagonistic actions on group 1 metabotrophic glutamate receptors. [R]

L-Theanine Research

L-theanine appears to provide a number of advantages, according to several research studies and animal research trials. Although experts believe it to be generally safe, there is still a lack of high-caliber human research to support its advantages and possible use as a dietary supplement.

L-Theanine and Working Memory

A randomized, double-blind, placebo-controlled trial was recently carried out to examine L-Theanine’s potential on working memory.

The participants were 50 to 69-year-old Japanese men and women and a battery of cognitive tests called Cognitrax was employed. Before the intervention, after a single dose of l-theanine, and after 12 weeks of consistent consumption, evaluations were conducted.

L-theanine lowered response times for attentional tasks, and it improved working memory performance by increasing the proportion of right answers and reducing the proportion of omission errors. This research concluded that l-theanine may help to increase attention, which would then improve working memory and executive functioning. [R]

L-Theanine on Stress and Anxiety

In a study of five randomized controlled trials with a total of 104 individuals, four of the studies found that L-theanine helped those who were in stressful situations feel less anxious and stressed out. [R]

People with schizophrenia or schizoaffective disorder were the topic of a different study that was published in the Journal of Clinical Psychiatry. L-theanine, according to research, reduced anxiety and eased symptoms with a healthy stress response. [R]

L-Theanine and Focus

A recent study discovered that a combination of L-theanine (97 mg) and caffeine (40 mg) improved the concentration of a group of young adults during difficult tasks. [R]

L-Theanine and Immunity

According to several studies, amino acids like L-theanine may potentially enhance the body’s immune system. According to a study in the journal Beverages, L-theanine may lessen the frequency of upper respiratory tract infections. [R]

A recent randomized control trial examined the effects of catechins and theanine on preventing influenza infection among healthcare workers. The study concluded that taking green tea catechins and l theanine benefits as a potential efficient influenza infection prophylactic amongst these healthcare workers for the elderly. [R]

L-Theanine and Cancer

L-theanine has also been linked to enhancing several chemotherapy medicines’ anti-tumor properties. Because of these encouraging results, scientists anticipate that L-theanine may also help chemotherapy work more effectively against cancer. [R]

L-Theanine and Hypertension

In one study, it was discovered that L-theanine helped persons whose blood pressure often rose after performing particular mental tasks. [R]

L-Theanine and Sleep

According to some studies, L-theanine may aid in relaxation, which may explain why it could be potentially helpful for obtaining a good night’s sleep.

In one study, scientists discovered that L-theanine doses of 250 mg and 400 mg significantly enhanced both animal and human sleep. [R]

Additionally, L-theanine 200 mg was demonstrated to assist in lowering resting heart rate, demonstrating its capacity to encourage sleep. [R]

Boys with attention deficit hyperactivity disorder (ADHD) may find it easier to sleep if they take L-theanine

The effects of L-theanine were examined on 98 boys between the ages of 8 and 12 in a double-blind research study. L-theanine chewable pills at the dosage of 100 mg were distributed twice daily to a randomized group. The opposite group was given a placebo.

The group taking L-theanine experienced longer, more peaceful sleep after six weeks. While the results are encouraging, further research is necessary before it can be established as safe and beneficial, particularly for kids. [R]

According to additional studies, L-theanine enhanced the quality of sleep for those with schizophrenia. [R]

L-Theanine FAQs

How much L-Theanine is in tea?

Depending on the type of tea and growing circumstances, green tea leaves L-theanine content can vary. However, green tea leaves typically have a weight percentage of L-Theanine of 0.24%. Accordingly, 48mg of L-Theanine would be present in a cup of green tea (200ml) made from one gram of dry leaves.

Does l-theanine help with anxiety?

Both animal and human research have demonstrated that L-theanine helps people feel less anxious. It functions by raising the brain’s GABA, serotonin, and dopamine levels. These neurotransmitters are in charge of controlling anxiety, sleep, and mood. Additionally, L-theanine raises alpha brainwave activity.

This may promote relaxation. [R]

Can l-theanine aid sleep?

Research shows L-Theanine can potentially be utilized to help consumers fall asleep. GABA, serotonin, and dopamine levels rise in the brain as a result. One of the things that these neurotransmitters control is sleep. Additionally, L-theanine has the potential to raise alpha brainwave activity, which is linked to relaxation.

Both animal and human studies have demonstrated that L-theanine has the potential to enhance the quality of sleep.
