L-Theanine is an amino acid found most commonly in tea leaves and in small amounts in Bay Bolete mushrooms. It can be found in both green and black tea. This amino acid impacts nerve impulses in the brain and the release of neurotransmitters, including GABA. It is known as natural anxiolytic because it can have a calming, sedative effect on the body and mind without making you feel drowsy.


In one study, L-Theanine was shown to reduce scores on a tension-anxiety test compared to placebo. Certain studies have found that L-Theanine can help to improve sleep quality in people with conditions that cause hyperactivity, including ADHD. L-Theanine may help to protect the brain by preventing excessive glutamate stimulation of brain cells (excitotoxicity), which some believe is linked to neurodegenerative disorders, stroke and schizophrenia. By blocking some of glutamate’s effects, L-Theanine may be able to offer neuroprotection for the aging brain. Some studies have also found that administration of L-Theanine after a stroke, ideally within 12 hours but potentially up to 24 hours later, may help protect brain cells and reduce damage caused by the stroke.


We provide pure micronized L-Theanine in the proper dose clinically shown to produce better sleep in a 6 week clinical study.
