Natural L-Theanine Powder – Premium Green Tea Extract for Calm Focus & Cognitive Wellness Solutions
Hefei Fushan Yuansheng Biotechnology Co., Ltd. adopts sophisticated water extraction technique to produce high purity Natural L-Theanine from the leaves of Camellia sinensis. Our solution contains 20%-60% standardised theanine which may be adjusted to suit a variety of formulation needs. Our product has good stability across a wide variety of pH and thermal processing conditions. Purity validated by HPLC. We have more than 13 years of experience in the plant extracts field. Our R&D team is supervised by a PhD. We assure consistency from batch to batch and we comply with international quality standards such as FDA GRAS and USP guidelines.
What is Natural L-Theanine?
Product is a unique non-protein amino acid found mostly in green tea leaves. Unlike other synthetic sources that may include inactive D-isomers, our natural source of this supplement is guaranteed to be 100% L-isomer via enzymatic fermentation or water extraction techniques.
This amino acid is known to increase alpha-wave activity in the brain, which enhances “calm focus”. It alters levels of neurotransmitters such as serotonin, dopamine and GABA without being sedating. That answers a major problem for firms making cognitive health products: how to provide mental clarity without the jitters that come with stimulants.
The molecular makeup of the molecule (N-ethyl-L-glutamine) gives it excellent water solubility and heat stability, thus it may be used in a wide variety of application forms.
Core Properties & Specifications
Our Natural L-Theanine demonstrates superior physicochemical characteristics that ensure formulation success:
| Parameter | Specification |
|---|---|
| Appearance | Light yellow to yellowish-brown powder |
| Active Content | Theanine 20–60% (customizable) |
| Testing Method | HPLC |
| Particle Size | 100% pass 80 mesh |
| Purity | ≥98% L-isomer |
| Water Solubility | ~540g/L at 25°C |
| Specific Rotation | +7.7° to +8.5° |
| Shelf Life | 3 years |
| Heavy Metals | Compliant (Arsenic tested) |
| Microbiology | Total Aerobic Count <10 CFU/g |
The ingredient retains its structural integrity following pasteurisation, UHT processing, and high-temperature extrusion. Its subtle umami flavour naturally hides the harshness of caffeine and polyphenols in beverage applications.
Key Technical Advantages
High-Activity Standardized Extraction
Our patented aqueous extraction technique removes undesirable chemicals and maintains the bioactive form of the amino acid. You’re getting a clean-label ingredient with constant strength.
Pollution Control Systems
We use modern purifying processes for the removal of pesticide residues and plasticisers. For formulations aimed at sensitive consumer groups, low-caffeine customisation is offered.
Batch Quality Stability
Multi-gradient content selections (20, 40, 60%) for accurate dose management. Each batch is stringently HPLC tested to ensure purity and to ensure no D-theanine contamination.
Regulatory Compliance Assistance
We provide China New Food Raw Materials standards, FDA GRAS status and European Pharmacopoeia specifications. Full paperwork is available including COA, allergen declarations and safety data sheets.
Application Solutions Across Industries
Nootropic Beverages & RTD Drinks
Natural L-Theanine is stable in the typical acidic conditions (pH 2.5-4.0) of fruit juices and energy beverages. It combines with caffeine to provide lasting mental vigour without the inevitable crashes, a key ingredient in “smart drink” formulas.
Dietary Supplements & Capsules
The ingredient pairs effectively with magnesium, GABA, or melatonin in sleep and stress relief supplements. Its high bioavailability ensures rapid absorption and noticeable cognitive benefits at 100–200mg dosages per serving.
Functional Gummies & Confectionery
Heat stability allows seamless integration into pectin or gelatin-based gummies. The powder survives heating phases without degradation, delivering standardized calm-focus benefits in consumer-friendly formats.
Anti-Aging Skincare & Cosmetics
Antioxidant properties support topical formulations targeting oxidative stress. The amino acid enhances skin barrier function and complements other active ingredients in anti-aging serums and creams.
Aquaculture & Animal Nutrition
Stress reduction benefits extend to livestock and aquaculture applications, where it improves feed conversion ratios and supports immune health under farming stress conditions.

Frequently Asked Questions
Q:How can I distinguish product from synthetic versions?
A:Use Chiral HPLC to detect D-theanine contamination and C14 carbon dating to confirm plant-based origin. Our product contains zero D-isomer and full botanical traceability.
Q:Does product lose potency during processing?
A:No. The compound withstands standard UHT, HTST pasteurization, and extrusion without significant degradation, ensuring your finished product retains full efficacy.
Q:What dosage supports a "calm focus" claim?
A:Clinical trials demonstrate noticeable alpha brain wave activity increases at 100–200mg per serving. We recommend this range for cognitive wellness positioning.
Q:Is it compatible with acidic fruit juices?
A:Yes. The ingredient remains stable in low-pH environments over extended shelf life periods without precipitation or activity loss.
Q:Are there known contraindications?
A:While GRAS-certified, it may enhance sedative medication effects. Always conduct compatibility testing during R&D phases for combination formulas.
Q:Is the product guaranteed?
A:We guarantee batch-to-batch consistency matching your approved samples. Every shipment undergoes rigorous testing compliant with Chinese, European, or US Pharmacopoeia standards before release.
Q:Does this extract contain caffeine?
A:Conventional green tea extracts contain 2–10% caffeine. We offer low-caffeine or decaffeinated solutions tailored to your formulation requirements.
