5 Benefits of L-Theanine

L-Theanine - The Anxiety Buster

What is L-Theanine?

L-theanine, a water-soluble, non-protein amino acid commonly found in green tea and some mushrooms, has been widely studied for its ability to encourage wakeful relaxation without sedation. 

Anxiety can be one of the most difficult emotions and mental states we struggle with. For some of us, it’s short lived and occasional. For others among us, anxiety is a very real and very difficult mood disorder that takes over one's life.

In general, l-theanine could be of surprising help and support for anxiety. The anti-anxiety effect of l-theanine is achieved through enhanced alpha brain wave activity and increased synthesis of GABA. Increased GABA, in turn, increases brain levels of dopamine and serotonin, resulting in general feelings of calm and well-being. Changes in brain electrical activity measured by EEG are dose-dependent, and are similar to beneficial EEG changes observed in meditation. 

Even though l-theanine and caffeine are found in great amounts in the same plant, l-theanine appears to keep the negative effects of caffeine at bay, while only supporting the good stuff.

L-theanine and caffeine taken together reduce high blood pressure and nervousness compared to caffeine taken alone. This may help explain why green tea, even though it has much higher levels of caffeine than coffee, gives people a much smoother ride to an alertness boost than coffee does.

This botanically-sourced compound can gently pull away anxiety and stimulate energy in a calming, not-so-over-the-top way. Naturally, this can also bring better brain function, memory and focus to the forefront.

Though more research is needed, this could possibly make l-theanine one day a natural therapy for neurological disorders such as Alzheimer’s disease or Parkinson’s. It could also help improve brain fog, too. *cough*cough* hello postpartum brain fog!

Issues with the brain like anxiety are one thing. Mood disorders like stress and depression are a whole other ballgame - yet are just as challenging. But much like anxiety and other mental state-related issues, l-theanine has a scientifically-proven way of going beyond lifting one’s spirits to help depression.

L-theanine has a significant effect on the release or reduction of neurotransmitters like dopamine and serotonin. It influences emotions due to its effects on the increased release of dopamine. L-theanine reduces brain serotonin concentration by either curtailing serotonin synthesis or increasing degradation in the brain.

If there’s anything that could be called the strongest foundation for health, getting high quality, restorative sleep would probably be it. Even better, l-theanine could be a great ally in this regard, too.

In close concert with its anti-anxiety, anti-stress, and anti-depression properties, l-theanine can offer powerful support for better sleep.

Stress, anxiety, and depression are all mental states and moods that can keep us from sleeping well. And if l-theanine can help these, it can surely aid in the sleep department.
