Revive Suntheanine (L-Theanine)
By REVIVE
L-Theanine is an amino acid naturally found in tea leaves, best known for its ability to promote a sense of calm without making you drowsy. Suntheanine® is a patented, pure form of L-Theanine made through a fermentation process that mimics how it’s created in nature. This ingredient supports relaxation, mental focus, and a balanced stress response by increasing calming brain chemicals like GABA and serotonin, as well as encouraging alpha brain waves, which are linked to a state of “relaxed alertness."*.
