L-Teanin

Overview What is L-Theanine? L-theanine is mainly found in tea and some natural sources. Naturally occurring , non protein synthesis stimulating, amino acid Primary used to help with sleep and reduce anxiety. Research Highlights Highlight: Findings from Individual Clinical Studies Please note: The statements below summarize findings from separate clinical studies and do not constitute direct claims about the benefits of our product. Summary Participants experienced enhanced sleep quality without drowsing effects [4] Indicated potential stress-reducing qualities. [2] Suggested mild cognitive improvement with caffeine. [1] Showed potential counteraction of blood pressure spikes in certain conditions. [3] Function How does it work? As indicated from clinical trails L-theanine can cross the blood-brain barrier. BBB filters blood to the brain; supplements crossing it can impact brain more directly. [7] Promoted increased alpha-waves in brain activity [8] The tendency of L-theanine to increase alpha waves may be the reason behind its stress and anxiety reducing effects. [5] In animal studies, L-theanine affected neurotransmitter signaling in the brain. Detailed Review The Current State of L-Theanine Research Summary of a five different randomized controlled trials 139 participants Sleep Enhances sleep quality without sedative effects, fostering a more relaxed brain state [4] One study found a 14% improvement in self assesed sleep quality Reduced sleep onset time, disturbance, and decreased use of sleep medication. test after L-theanine compared to placebo. [5] Relaxation Promotes a relaxed state without causing drowsiness. [4] Clinical trial found a reduction in stress-relatedIndicated by reductions in the depression scale, anxiety inventory, and sleep quality index. symptoms after taking L-theanine, compared to the control group. [5] Same study suggests that L-theanine may promote mental health in those with stress-related issues and cognitive challenges. [5] Cognition Offers mild cognitive-enhancing effects, especially when combined with caffeine. [1] L-theanine improved cognitive functions Elevated verbal fluency and executive function scores. , especially in those with lower baseline scores. [5] Blood Pressure Suppresses the blood pressure-raising effects of caffeine. [2] Counteracts blood pressure spikes during stressful situations. [3] Dosage Suggested Intake 1 Up to 65kg bodyweight , 2 65 to 85kg bodyweight or 3 +85kg bodyweight capsules before bed or as per needed With or without food No cycle needed Consumed until finished Drawbacks Adverse effects L-theanine is well-tolerated in humans with no reported adverse reactions or toxicity. One rodent study showed no toxic effects when given 4,000 mg of L-theanine per kg of body weight daily for 13 weeks. [6] Other animal studies have found no toxicity even at high doses. L-theanine can potentially lower blood pressure in certain situations. As a precaution, individuals on prescribed blood pressure medications should consult with their doctor before consuming L-theanine supplements.
