About the amino acid L-theanine
L-theanine (gamma-glutamylethylamide) is a non-protein-forming amino acid that occurs naturally in the leaves of the tea bush. In a regular cup of tea, there is about 25-60 mg of theanine. The amino acid has many functions in the body and is popular to take before going to bed. The L in L-theanine comes from the fact that theanine mainly occurs in the form of L-isomers.
L-theanine in the body
Recently, several studies have shown a link between L-theanine and the release of the neurotransmitters serotonin and dopamine in the brain. Dopamine has an effect on the brain's reward system while higher serotonin levels make us calmer. There are studies that show that L-theanine can be taken in connection with stress-related disorders (1), and that the substance has an impact on our sleep quality (2). To get the best effect, you should take L-theanine just before you go to bed. However, more studies are needed to be able to draw conclusions, and it’s best to try it out for yourself.
Finding the right dose of L-theanine
Healthwell L-Theanine 100 is suitable for those who want a lower dose of L-theanine. The supplement is easy to combine with other supplements that also contain L-theanine or for example GABA. With Healthwell L-Theanine 100 you can also adjust the dosage as you wish. For those who are looking for a more high-dose supplement, there is Healthwell L-Theanine 200 and Healthwell L-Teanin 400.
We recommend following the dosage recommendation on the package (1 capsule daily before bedtime or as prescribed) to be sure to avoid any side effects. However, there are no studies suggesting that L-theanine is harmful or that the substance has any adverse side effects.
