L - THEANINE HELP PROMOTE CALMNESS: L-Theanine has been shown by several studies to help de-stress the body. It does this by reducing the binding of the excitatory neurotransmitter glutamate to its receptors and stimulating the production of the inhibitory neurotransmitter GABA. The chemical imbalances between these neurotransmitters can lead to cognitive decline. The best part is,  L-Theanine produces its anti-anxiety and calming effects without producing sleepiness or impairing motor behavior. L-Theanine supplementation is found to be most beneficial for those who suffer from stress and stress-induced anxiousness. 

L - THEANINE HELPS SUPPORTS IMMUNITY: Stress can take a toll on the immune system in the long-term, resulting in more frequent episodes of illness and infection. A number of recent studies have suggested that L-Theanine supplementation can improve the body’s immune system by enhancing δ T lymphocyte function and decreasing anti-inflammatory cytokines and interleukins. After being absorbed into the body, L-theanine can penetrate the blood-brain barrier and regulate the secretion of neurotransmitters of central nervous system cells and levels of hormones such as corticosterone and adrenaline (stress hormones) in the serum. 

SUPPORTS HEALTHY STRESS RESPONSE: Stress can greatly diminish your quality of life, both emotionally and physically. The elevated serum levels of stress hormones like catecholamine and adrenaline cause increased oxidative stress in the brain which impairs cognitive function and reduce performance. L-theanine’s structure holds a close relationship to the brain-signalling chemical glutamate. While glutamate is the brain’s most excitatory neurotransmitter, L-Theanine binds to the same brain cell receptors and blocks them to glutamate’s effects. This action produces an inhibitory effect which helps reduce stress, induce calming and relaxing effect. 

L - THEANINE MAY IMPROVE COGNITIVE FUNCTION: There exists a link between anxiety, stress, and the brain’s most fundamental function, maintaining cognition. Stress has a negative impact on the way a person thinks and makes a decision. L-Theanine crosses the blood-brain barrier, it has the ability to modulate inhibitory neurotransmitters, serotonin and dopamine to bring about calming effects. L-Theanine can improve cognition by enhancing the alpha brain wave activity, it helps stabilize cognitive function affected by stress hormones. L-Theanine decreases levels of corticosterone, which when elevated can inhibit learning ability and memory formation. 

L - THEANINE PROMOTES BETTER QUALITY OF SLEEP: Clinical studies have found L-Theanine supplementation as a sleep aid to be safe, effective, non-addictive and without causing side effects commonly associated with prescription sleep medications. L-Theanine produces sleep-enhancing benefits through anxiolysis. The supplement does not cause daytime drowsiness, hence can be used for relaxation and induction of sleep at any time of the day. Theanine improves sleep efficiency, produces less wakefulness after sleep onset, reduces fatigue upon rising and provides feelings of prolonged and restful sleep.
