Examine - Theanine

The Examine.com article provides a comprehensive overview of L-theanine, an amino acid predominantly found in tea leaves. L-theanine is recognized for promoting relaxation without causing drowsiness, attributed to its ability to cross the blood-brain barrier and enhance alpha-wave activity in the brain. This modulation of brain activity may contribute to stress reduction and improved focus. When combined with caffeine, L-theanine has been shown to enhance cognitive performance and mood, suggesting a synergistic effect. The article notes that L-theanine is generally safe for most individuals, with minimal reported side effects. Incorporating L-theanine through dietary sources like green tea or as a supplement may support relaxation and cognitive function. However, individual responses can vary, and it's advisable to consult a healthcare professional before initiating any new supplement regimen.
