L-Theanine (from green tea)... 225 mg... †
† Daily Value not established
What Is It?
First discovered in 1949, L-theanine is a unique amino acid found primarily in green tea. Researchers have often wondered why green tea, despite its caffeine content, tends to relax individuals without making them drowsy. Similarly, those engaging in meditation practices may drink tea to dispel mental sluggishness and yet not become mentally agitated, as is typical with the consumption of too much coffee. AOR's Zen Theanine provides an optimal dose of this remarkable amino acid. Zen Theanine is fast-acting, with its effects felt within 1 hour of consumption.
What Does It Do?
Primary Uses: L-Theanine helps reduce nervousness and restlessness, and promotes a relaxed alertness. L-theanine rapidly enters the system when ingested (within roughly 40 minutes) and heightens the index of the brain wave that is known to be linked to a state of relaxed wakefulness. L-theanine influences the levels of the neurotransmitters dopamine, serotonin and GABA in the brain, positively affecting mood, sleep and learning capacity.
Secondary Uses: L-theanine also appears to protect against certain so-called "excitotoxins." It modulates the motor-stimulation associated with caffeine, and it inhibits some of the actions of norepinephrine (a stress hormone) in the central nervous system.
Who Should Take It?
Zen Theanine is beneficial for those suffering from stress or feelings of apprehension, especially when the ability to work, study or sleep is affected.
