Natural Green Tea Extract 99% L-Theanine Powder High Purity Nootropic for Relaxation and Focus Support Water Soluble Food Grade
HIGH PURITY 99%
L-THEANINE POWDER
L-Theanine is a unique non-protein amino acid naturally found in green tea leaves. Known as a "natural nootropic," our 99% purity L-Theanine is crystalline and 100% water-soluble. It is highly valued in the B2B market for its ability to promote relaxation without drowsiness, making it a cornerstone ingredient for cognitive enhancement formulas, stress-relief supplements, and functional beverages. Its synergy with caffeine makes it a favorite for "Smart Coffee" and focus-driven dietary supplements.
TECHNICAL SPECIFICATIONS
CORE HIGHLIGHTS
Ultra-High Purity 99%+
Strictly controlled HPLC testing ensures a minimum of 99% active L-Theanine with minimal D-Theanine impurities, meeting the highest USP standards.
Complete Solubility
Instant and clear dissolution in water at room temperature. No sediment or cloudiness, making it perfect for premium functional beverage shots.
Neutral Taste Profile
Unlike many amino acids, our L-Theanine has a clean, slightly umami/sweet taste, allowing for easy masking in flavored gummies and drinks.
Caffeine Synergy
The "Alpha Wave" catalyst—promotes focus and offsets the jitters and "crash" associated with caffeine consumption.

BIOLOGICAL FUNCTION
Cognitive Enhancement & Focus
Increases Alpha-wave activity in the brain, which is associated with a state of "relaxed alertness" and better concentration.
Stress & Anxiety Regulation
Supports healthy levels of GABA and serotonin, helping to modulate the body's response to environmental stressors.
Sleep Quality Improvement
Promotes a calm state before bedtime without acting as a sedative, leading to deeper and more restorative sleep cycles.
Cardiovascular Support
Assists in the production of nitric oxide, which helps relax blood vessels and support healthy blood pressure levels.

FREQUENTLY ASKED QUESTIONS
Q1: What is the ratio of L-Theanine to D-Theanine in your product?
Answer: Our product is highly stereospecific. By using optimized extraction and purification processes, we ensure the L-form is ≥ 99%, with negligible D-form presence, maximizing biological efficacy.
Q2: Can L-Theanine be used in clear carbonated beverages?
Answer: Yes, our L-Theanine is 100% water-soluble and stable across a wide pH range. It does not cause cloudiness or precipitation in clear beverages, even under carbonation.
Q3: How does L-Theanine synergize with Caffeine?
Answer: Research shows that L-Theanine can cross the blood-brain barrier and modulate the stimulatory effects of caffeine. It promotes relaxation and alpha-wave production, resulting in "clean energy" without the typical heart palpitations or jitteriness.
