What Is L-Theanine Best Used For?

Theanine is a free amino acid unique to tea, which only accounts for 1-2% of the weight of dried tea leaves, and is one of the most abundant amino acids contained in tea.

The main effects and functions of theanine are:

1.L-Theanine may have a general neuroprotective effect, L-Theanine can promote positive changes in brain chemistry, promote alpha brain waves and reduce beta brain waves, thus reducing feelings of stress, anxiety, irritability and agitation caused by coffee extraction.

2.Enhance memory, improve learning ability: studies have found that theanine can significantly promote the release of dopamine in the brain center, improve the physiological activity of dopamine in the brain. Therefore L-Theanine has been shown to potentially improve learning, memory and cognitive function, and enhance selective attention in mental tasks.

3.Improve sleep: ingesting theanine at different times of the day can adjust the degree of balance between wakefulness and drowsiness and keep it at a suitable level. Theanine will play a hypnotic role at night, and wakefulness during the day. L-Theanine reassuringly optimizes the quality of their sleep and helps them sleep more soundly, which is a huge benefit for children suffering from Attention Deficit Hyperactivity Disorder (ADHD).

4.Antihypertensive effect: studies have proved that theanine can effectively reduce spontaneous hypertension in rats. Theanine shows the effect of lowering high blood pressure can also be regarded as a stabilizing effect to a certain extent. This stabilizing effect will undoubtedly help the recovery of physical and mental fatigue.

5.Prevention of cerebrovascular disease: L-theanine may help prevent cerebrovascular disease and reduce the impact of cerebrovascular accidents (i.e. stroke). The neuroprotective effect of L-theanine after transient cerebral ischemia may be related to its role as an AMPA glutamate receptor antagonist. Rats treated with L-theanine (0.3 to 1 mg/kg) prior to experiencing experimentally induced repeated episodes of cerebral ischemia may exhibit significant reductions in spatial memory deficits and significant reductions in neuronal cellular decay.

6.Helps improve attention: L-Theanine significantly optimizes brain function. this was clearly demonstrated in a 2021 double-blind study where a single dose of 100 mg of L-Theanine and a daily dose of 100 mg for 12 weeks significantly optimized brain function. l-Theanine resulted in a reduction in reaction time for attention tasks, an increase in the number of correct answers, and a reduction in the number of omission errors in working memory tasks. The number decreased. These results were attributed to L-theanine reallocating attentional resources and optimally improving mental focus. The researchers concluded that L-theanine may help to improve attention, thereby enhancing working memory and executive function.

Theanine is suitable for people who are stressed and easily fatigued at work, those who are prone to emotional stress and anxiety, those with memory loss,those with low physical fitness,menopausal women,regular smokers,those with high blood pressure,and those with poor sleep.
