    Embodies the essence of pure, high-quality dietary supplement ingredients

  • L-THEANINE

    Calm Mind, Clear Focus Naturally

    L-Theanine

    L-THEANINE

    L-Theanine is a unique amino acid found primarily in green tea leaves. It's highly valued for its ability to promote a state of relaxed awareness without causing drowsiness. Our L-Theanine is manufactured through a precise fermentation process, ensuring high purity and quality. This process yields a Non-GMO product that is more cost-effective than traditional natural extractions while maintaining a premium profile. It's the ideal ingredient for supplements aimed at supporting focus, stress reduction, and healthy sleep cycles.

    Bulk L-Theanine Raw Material Manufacturer & Global Supplier

    L-Theanine (C7H14N2O3) is a premium amino acid known for its cognitive and relaxation benefits. As a dedicated B2B raw material supplier, Purecium provides high-purity L-Theanine tailored for global distributors, contract manufacturers (CDMOs), and functional food brands.

    Formulation & Stability:

    Its excellent water solubility and clear solution profile make it ideal for low-pH energy drinks, liquid shots, and functional beverages, without precipitation or degradation issues. Furthermore, it exhibits excellent physical stability when formulated with other trending ingredients like Magnesium, GABA, or Ashwagandha, avoiding hygroscopic clumping during long-term storage and blending.

    Sources & Production Methods

    We offer L-Theanine derived from three primary production methods to meet diverse brand claims, from industrial-scale cost-efficiency to "Clean Label" natural ingredient preferences:

    1. Microbial Fermentation (Non-GMO Corn): A highly cost-effective, eco-friendly approach. Our fermented L-Theanine utilizes non-GMO corn as the starting substance. This natural process is favored by consumers and premium supplement brands.
    2. Chemical Synthesis: Utilizing pyroglutamic acid as the starting material, this process ensures precise conversion and high purity. It is highly scalable, making it a reliable and economical source for bulk dietary supplement formulations.
    3. Green Tea Extraction: Extracted directly from green tea leaves, this retains the essence of its botanical origin, catering specifically to herbal supplements and authentic tea-based products.

    Quality Assurance: Regardless of the method, we ensure strict control of chiral impurities. Our L-Theanine undergoes rigorous HPLC testing to minimize D-Theanine residue, guaranteeing safety and efficacy.

    Health Benefits & Mechanism of Action

    L-Theanine crosses the blood-brain barrier to modulate brain chemistry gently. It increases the levels of calming neurotransmitters—such as GABA, serotonin, and dopamine—while inhibiting the overactivity of glutamate, an excitatory neurotransmitter.

    • Stress & Anxiety Reduction: Helps lower cortisol levels and regulates the body's stress response.
    • Cognitive Enhancement: Promotes alpha brain wave production, linked to a state of "relaxed alertness." Often paired with caffeine to counteract jitters while boosting focus.
    • Sleep Quality: Induces relaxation without daytime drowsiness or sedation.
    • Immune Support: May assist immune health by increasing the production of gamma-delta T cells.

    Compliance & Global Supply Chain

    Our L-Theanine is food-grade and complies with FDA GRAS (Generally Recognized as Safe) status, ensuring safe formulation for the US market. For our European clients, we navigate strict EU regulations to facilitate smooth customs clearance and Novel Food compliance.

    We guarantee a consistent, long-term supply chain to protect our clients from market fluctuations. Our facilities operate with a designed annual capacity of 300 MT for synthetic and 1,200 MT for fermented L-Theanine.

  • Frequently Asked Questions (FAQ) for B2B Buyers

    1. Do you sell finished L-Theanine products or to individual consumers?

    No, Purecium strictly supplies raw ingredients directly to B2B distributors, contract manufacturers (CDMOs), and end-brands. We do not engage in B2C retail. However, we can partner with reliable contract manufacturers to facilitate white-label services (including tablets, hard/soft capsules, and gummies) for our B2B clients.

    2. What is your minimum order quantity (MOQ) and bulk packaging standard?

    Our MOQ for bulk orders is 25 kg. The standard industrial packing is a 25kg/drum.

    Drum dimensions: 40cm x 40cm x 50cm.

    Weight Specifications: Net weight 25 kg / Gross weight 28 kg.

    3. How do you verify the origin of natural fermented L-Theanine vs. synthetic?

    While both offer ≥ 98% purity and identical physiochemical properties, fermented L-Theanine is derived from non-GMO corn, making it highly cost-effective and eco-friendly. Origin is strictly verified via Carbon-14 (C14) testing. Our fermented L-Theanine shows a bio-based carbon content of >97%, whereas synthetic batches show minimal bio-based carbon. C14 reports are available upon request.

    4. Do you offer specific particle (mesh) sizes for direct tableting and capsule filling?

    Yes. To accommodate different manufacturing equipment, our standard L-Theanine is a 60-80 mesh fine powder. For manufacturers requiring excellent flowability for high-speed capsule filling or direct compression tableting, we also supply a specialized 20-40 mesh granular grade.

    5. What finished product formats (dosage forms) are most suitable for your bulk L-Theanine powder?

    Due to its high water solubility, clear solution profile, and thermal stability, our raw L-Theanine powder is highly versatile. It is commonly formulated into tablets, hard capsules, softgels, functional gummies, and liquid applications like ready-to-drink (RTD) sports beverages and low-pH energy shots.

    6. What quality and regulatory certifications accompany your L-Theanine raw material?

    Our L-Theanine is food-grade and FDA GRAS (Generally Recognized as Safe) compliant. We manufacture under strict quality control systems and provide ISO9001, Kosher, Halal, and FSSC22000 certifications to support your end-product's compliance in global markets.

    7. What is the shelf life, and do you provide stability data for formulation?

    The standard shelf life is 24 months when stored in a tightly sealed, dry environment, away from direct light. We support R&D teams by providing comprehensive data from both accelerated and long-term stability tests upon request.

    8. What is your annual manufacturing capacity to ensure stable bulk supply?

    We guarantee supply chain resilience and long-term consistent availability. Our production facilities operate with a designed annual capacity of 300 MT for synthetic L-Theanine and 1,200 MT for fermented L-Theanine.

    9. What are the delivery times and global shipping options?

    US, Canada & Mexico: Fast fulfillment with pickup available from our U.S. warehouse within 2 days of order placement. Door-to-door delivery logistics can also be arranged.

    Global Regions (EU, UK, etc.): International orders are shipped directly from our facilities in China, with dispatch typically within one week of order placement.
