Theanine Powder

In a world of constant overstimulation, the demand for safe, effective, and non-sedating calming agents has never been higher. Our Premium Theanine Powder meets this demand head-on. This unique amino acid, renowned for promoting "alert relaxation," is the cornerstone ingredient for next-generation nutraceuticals targeting stress, focus, and sleep.

We supply certified Suntheanine®, the globally recognized and patented form of L-Theanine, produced via a proprietary enzymatic process. This guarantees 100% pure L-isomer, free from the inactive D-form, ensuring maximum bioavailability and consistent, reliable results for your formulations. Partner with us to deliver scientifically-backed mental wellness solutions to your customers.

Purity Defined by Process. While L-Theanine is naturally found in green tea (Camellia sinensis), our ingredient is not a simple tea extract. We provide the Suntheanine® brand, manufactured through a patented bio-synthesis process that mirrors nature's pathway without the variability of agricultural sourcing.

● Patented & Guaranteed Purity: The Suntheanine® process utilizes a specific enzyme to convert pharmaceutical-grade L-glutamic acid and ethylamine into pure L-Theanine. This method ensures:

* >99.5% Chemical Purity

* 100% L-Isomer Form (crucial for biological activity)

Zero D-Theanine (the inactive, potentially competing isomer)

● Non-GMO & Allergen-Free: The raw materials and process are meticulously controlled, resulting in a non-GMO, gluten-free, and allergen-free ingredient suitable for the most sensitive consumer demographics.

● Supply Chain Transparency: As a direct partner, we offer full traceability and documentation, providing the confidence and security required by global brands.

Our Theanine Powder  is a single, high-purity molecule, defined by its specific chemical and isomeric properties.

Every batch is supported by a comprehensive Certificate of Analysis, verifying its identity, purity, and safety.

Standard Specifications (COA):

The superiority of our Theanine lies in its manufacturing process, which ensures absolute isomeric purity.

* Enzymatic Synthesis (Patented): Pharmaceutical-grade precursors (L-Glutamic Acid and Ethylamine) are combined in a bioreactor with a specific, proprietary enzyme. This catalyst selectively produces only the biologically active L-Theanine isomer.

* Purification: The resulting solution undergoes multiple stages of purification, including advanced filtration and crystallization, to remove any residual reactants or by-products.

* Crystallization & Drying: The purified Theanine is crystallized under controlled conditions to form a consistent, free-flowing powder.

* Quality Control & Packaging: The final powder is rigorously tested against the Suntheanine® and our internal COA specifications. It is then packaged in moisture-controlled, food-grade packaging to ensure stability.

* Certified Suntheanine®: The gold-standard, patented ingredient backed by over 50 clinical studies.

* Guaranteed 100% L-Isomer: Ensures full biological activity and efficacy, unlike racemic mixtures.

* Exceptional Purity: ≥99.0% Theanine content with minimal impurities.

* Superior Solubility: Highly soluble in water, making it ideal for beverage, powder, and liquid formulations.

* Neutral Taste & Odor: Does not impart bitter or off-flavors, minimizing the need for flavor-masking agents.

* GRAS & Regulatory Compliance: Generally Recognized As Safe (GRAS) for use in various food and beverage categories, simplifying your product development.

The effects of pure L-Theanine (Suntheanine®) are well-documented in human clinical trials, focusing on its dual action on the mind.

Promotes Relaxation Without Drowsiness: L-Theanine increases alpha brain wave activity, associated with a state of "wakeful relaxation." It reduces feelings of stress and anxiety without causing sedation. 

* Enhances Focus and Attention: By mitigating distracting stress responses, L-Theanine improves the ability to concentrate on tasks. Studies show it can be synergistic with caffeine, improving cognitive performance while smoothing out caffeine's negative side effects like jitters. [Reference: Biological Psychology]

* Supports Quality Sleep: By promoting relaxation, L-Theanine can help improve sleep latency (time to fall asleep) and sleep quality, not by acting as a sedative, but by calming an overactive mind.

* Neuroprotective Properties: Research indicates L-Theanine may support cognitive health by modulating glutamate receptors and supporting the production of key neurotransmitters.

* Clinical Dosage: The effective dosage used in clinical studies typically ranges from 100 mg to 400 mg per day.

Formulate with a proven cognitive health ingredient across multiple delivery systems.

* Dietary Supplements: Stress relief and relaxation capsules, tablets, and softgels. Cognitive enhancement and nootropic stacks (often paired with caffeine).

* Functional Foods & Beverages: Calming drinks, sleep teas, ready-to-drink (RTD) relaxation beverages, and functional shots.

* Powdered Formulations: Stick packs for on-the-go stress relief, smoothie boosts, and sleep drink mixes.

* Gummies & Chewables: A popular delivery format for stress and sleep supplements, where its neutral taste is a significant advantage.

Q1: What is the difference between Suntheanine® and other L-Theanine sources?
A1: Suntheanine® is a specific, patented ingredient produced via enzymatic synthesis, guaranteeing 100% L-Theanine. Other sources, like generic synthetic processes or green tea extracts, can contain a racemic mixture (D- and L-Theanine), which is less effective. Suntheanine® is the most clinically researched form.

Q2: Is L-Theanine safe? Are there any side effects?
A2: L-Theanine is exceptionally safe and well-tolerated. It is not a sedative and does not cause dependency. Clinical studies have reported no significant side effects even at high doses. It is GRAS-affirmed for use in foods and beverages.

Q3: Can L-Theanine be used in combination with caffeine?
A3: Absolutely. This is one of its most popular applications. L-Theanine mitigates the jitters and anxiety sometimes caused by caffeine while synergistically enhancing focus and attention, leading to a state of "calm energy."

Q4: What is your minimum order quantity (MOQ)?
A4: Our standard MOQ for Suntheanine® is 1 kg. Sample quantities are available for qualified B2B partners for R&D and testing purposes.

Q5: Do you provide technical and regulatory support?
A5: Yes. As a specialist supplier, we provide comprehensive technical data sheets, COAs, and documentation to support your regulatory filings (e.g., for FDA, EFSA, or other national authorities).

Q6: Is this product suitable for vegan and vegetarian formulations?
A6: Yes. Our L-Theanine powder is produced via a fermentation-based enzymatic process and is entirely plant-derived, making it suitable for vegan and vegetarian products.
