L-Theanine

L-theanine is a naturally occurring and distinctive amino acid present in tea leaves. Research has demonstrated that L-theanine has stress-reducing properties and promotes relaxation without inducing drowsiness. It is effective in alleviating nervousness resulting from overwork and reducing irritability through its influence on various changes in the brain. Human studies further suggest that L-theanine is beneficial for enhancing focus, attention, and mental clarity, while also mitigating the negative side effects associated with caffeine consumption.
