Why you'll love it

Because you want to relax, but aren’t ready for bed. L-Theanine is a unique amino acid because unlike its counterparts, it is not used to form proteins or enzymes, and cannot be found readily in the diet. The main dietary source of L-Theanine is green and black tea, though the amount consumed by an individual on a daily basis is not usually enough to provide a therapeutic effect. It’s structure is similar to glutamine and easily crosses the blood-brain barrier so it can work directly on the central nervous system. 

It is most well known and researched for its ability to promote relaxation and fight stress and anxiety without the typical sedation side effect experienced with most other supplements with similar benefits. It can increase dopamine and GABA receptors in the brain which essentially means it can help to slow down the feelings of fear and stress when neurons become over excited. 

Interestingly, it has also demonstrated an ability to improve concentration and focus and may show some benefit in individuals who have stressful jobs that require high levels of cognitive functioning, or require sustained attention over prolonged periods of time. 

If you tend to be one of those people who lie awake at night running through tomorrow’s To Do list, or tossing and turning with worry, L-theanine may help lull you into the restful sleep you deserve. While it doesn’t cause drowsiness like many other sleep aids, it can help to reduce the stress and anxiety that is keeping you up at night. It can be part of a treatment plan for someone with moderate to severe insomnia, though we recommend working with your primary care provider to determine the root cause of your sleeping troubles.

Why this formula?

Theanine can be prepared by one of three methods: isolation from tea leaves, chemical synthesis, or biosynthesis. Due to the high cost and low yield of theanine from tea leaf extraction, this method is less commonly used in commercial settings. Chemical synthesis of theanine is high yielding and may be cost effective, but supplements prepared by chemical synthesis often contain a racemic mixture of both L-theanine and D-theanine. It is not known if D-theanine has the same effects as L-theanine. Due to the limitations with extraction or chemical synthesis of theanine, biosynthesis has the strongest potential for producing theanine for dietary supplements.

How much do I really need?

L-Theanine is generally well tolerated at doses between 100 and 400mg and for individuals looking to use it to help maintain a sense of general well being and relaxation, a dose of 225mg daily is ideal. If you are working with your primary care provider and using L-Theanine as part of your treatment plan, they may recommend a different dose more tailored to your individual needs.
