Clinical Trials

l-theanine adjunct to sertraline for major depressive disorder: A randomized, double-blind, placebo-controlled clinical trial.

This study looked at whether adding l-theanine, a substance found in green tea that affects the brain, can help in the treatment of major depressive disorder (MDD). Researchers wanted to see if it worked and was tolerable for patients. The study's results could indicate a new approach to treating MDD.
