What does L-theanine do?
Though L-theanine doesnt help build protein, it still serves an important function in our bodies.

Unlike sedatives, L-theanine doesnt seem to dull the senses, he explains.
L-theanine may impact the production of serotonin anddopamine, the hormones affect the quality of our mood and emotions.

It may also affect our levels of the stress hormonecortisol.
According to Alamdari, L-theanine can work for stressespecially at certain doses.
Most importantly, L-theanine wont cause the jitters or a crash.

These effects dont appear to come at the cost of performance.
Reaction time and focus typically remain stable, and in some cases, improve.

Thats about two to four cups of matcha or around ten cups of regular green tea.
