L-theanine is an amino acid primarily found in green tea. One of its key advantages is its ability to promote relaxation and reduce stress. L-theanine stimulates the production of alpha brainwaves, which are associated with a state of calm and mental clarity. This amino acid can help improve focus and attention while inducing a sense of relaxation without causing drowsiness.

L-theanine has been studied for its potential to support sleep quality by promoting relaxation and reducing anxiety. It may help individuals achieve a more restful sleep and wake up feeling refreshed. L-theanine also exhibits neuroprotective properties, supporting brain health and cognitive function. It may enhance memory, attention, and overall cognitive performance. L-theanine has been associated with a potential positive impact on mood by increasing levels of neurotransmitters such as serotonin and dopamine, which are involved in regulating mood and emotions.
