About L-Theanine
L-theanine is an amino acid derived from green tea, known for its relaxation-inducing effects. Synthesized in the roots of tea plants and transported to the leaves, L-theanine comprises about 2% of the total dry weight of green tea leaves. It is responsible for both the taste and the calming effects of green tea.
Suntheanine® is a patented form of L-theanine produced in Japan, which promotes an alert state of relaxation by increasing alpha brain waves (indicating a relaxed, alert state) and decreasing beta brain waves (indicating an awake, excited state of mind). Research shows that supplemental L-theanine crosses the blood-brain barrier within 30 minutes, exerting its effects directly on the brain.
Benefits:
- Promotes Relaxation Without Drowsiness: Known for its ability to induce relaxation without causing drowsiness.
- Rapid Effect: Takes effect within 30-40 minutes of intake.
- Improves GABA Levels: Helps increase GABA (gamma amino butyric acid) levels, an important neurotransmitter for nervous system function.
- Eases Stress and Tension: Helps ease stress and everyday nervous tension.
- Enhances Mood and Alertness: Promotes a positive mood and maintains alertness.
- May Enhance Cognitive Performance: May improve cognitive performance and attention to detail.
Research on L-Theanine with Suntheanine®:
Studies on L-theanine, including those with Suntheanine®, indicate that even extremely high doses of theanine cause little to no harmful psychological or physical effects. Research in rats has shown neuroprotective effects and anti-stress benefits. In a double-blind study, a single dose of L-theanine was found to reduce perceived stress during a mental math task.
L-theanine is used as a countermeasure to nervousness and tension, supporting mental tranquility and normalizing the body’s stress response. Suntheanine® may condition the body to handle stressful situations more effectively.
