The benefits of L-Theanine

As you may know, the brain emits weak electrical impulses (brain waves) that can be measured on the surface of the head. Brain waves are classified into four categories (delta, theta, Beta and alpha) – each with an associated mental state.

Brain waves are classified into four categories (delta, theta, Beta and alpha) – each with an associated mental state.

Delta is seen only in the deepest stages of sleep.

Theta is seen in light sleep or drowsiness.

Beta is seen in awake normal alert and focused stages of the day, e.g. at work. However in highly stressful situations, where there is difficulty in mental concentration some people find it difficult to wind down into other states.

Alpha is present in relaxed, calm, lucid wakefulness where there is a relaxed and effortless alertness. It is well known that alpha brain waves are generated during a relaxed state and therefore alpha waves are used as an index of relaxation.

The amino acid theanine directly stimulates the production of alpha brain waves, creating a state of deep relaxation and mental alertness similar to that achieved through meditation. In one study, alpha waves were observed within approximately 40 minutes after taking L-theanine.

L-theanine is involved in the formation of the inhibitory neurotransmitter, gamma amino butyric acid (GABA). GABA influences the levels of two other neurotransmitters, dopamine and serotonin, producing the key relaxation effect and improved memory and learning ability.
