Product Description

What is L-theanine ?

Theanine is an amino acid found in tea and some mushrooms. It comes in two forms: L-theanine and D-theanine. L-theanine is the most common form.
Theanine is similar to glutamate, a naturally occurring amino acid. Glutamate helps transmit nerve impulses in the brain. Theanine sometimes acts like glutamate in the body. But other times it seems to block the effects of glutamate. Theanine might also affect the brain chemicals GABA, dopamine, and serotonin.
People use L-theanine to improve mental function. It is also used for anxiety, mental impairment, stress, and other conditions, but there is no good scientific evidence to support these uses.
L-theanine is an amino acid. The human body does not produce this compound, and it is not essential for humans. Green tea, black tea, and certain types of mushroom naturally contain L-theanine.
L-theanine may affect the levels of certain chemicals in the brain. These include serotonin and dopamine, which influence mood, sleep, and emotion, and cortisol, which helps the body deal with stress.A change in the balance of these chemicals can change a person's mood or stress levels.
Small studies and tests on animals have shown that L-theanine may offer a range of benefits. Experts consider it to be generally safe, but there is currently a lack of high-quality research in humans to confirm its benefits.

The benefits of our L-theanine
 

Anxiety and stress relief:Sipping on a hot cup of tea can help you feel at ease, and research suggests that it not only relaxes the mind, but it also does so without causing drowsiness.
In a review of five randomized controlled trials that included 104 participants, four trials linked L-theanine with reduced stress and anxiety in people experiencing stressful situations.
Another study published in the Journal of Clinical Psychiatry focused on people living with schizophrenia or schizoaffective disorder. Researchers found that L-theanine decreased anxiety and improved symptoms.

Better immunity:Some research suggests that L-theanine may improve the function of the body's immune system. One study published in the journal Beverages found that L-theanine could help decrease upper respiratory tract infections.
Another one found that green tea catechins- antioxidants- and theanine could be effective at preventing the flu (Trusted Source, Trusted Source).
Another studyTrusted Source found that L-theanine could help improve inflammation in the intestinal tract. However, more research is needed to confirm and expand on these findings.

The application of L-theanine

Supports Restful Sleep: Due to its relaxing effects on the nervous system, L-theanine may help improve sleep quality. 
A small study of 30 adults found participants who took 200 mg of L-theanine per day for four weeks experienced reductions in sleep latency-the time it takes to fall asleep. They also saw reductions in sleep disturbance and use of sleep medication compared to participants who took a placebo treatment.
A study of 160 people tested the efficacy of various supplements, including L-theanine, for their sleep benefits. Researchers found supplementing with 200 mg of L-theanine for seven days significantly improved sleep problems such as trouble falling and staying asleep.
Could Boost Cognitive Function: L-theanine directly impacts brain function, and study findings suggest L-theanine supplements may benefit memory and attention by improving the brain's ability to focus and remember information. 
A study including 69 Japanese adults between the ages of 50 and 69 showed a single dose of 100.6 mg of  L-theanine improved reaction time and working memory on cognitive tests.
Additionally, a study of 32 healthy young adults found doses of L-theanine ranging from 100 to 400 mg significantly improved attention and information processing compared to baseline.
L-theanine also has neuroprotective properties, meaning it may protect brain cells from age-related damage and reduce the risk of cognitive conditions such as Parkinson's Disease. Green tea's high content of L-theanine is thought to be a major reason why people who drink green tea regularly are at a lower risk of developing dementia.
