Active Ingredient Profiles
Green Tea Polyphenols (98%)
Green Tea Polyphenols represent the primary bioactive fraction of Camellia sinensis leaf extract. Standardized to a minimum of 98% total polyphenol content, this high-potency ingredient is valued across multiple industries for its exceptional antioxidant capacity and broad-spectrum biological activity.
Key functional properties include:
- Antioxidant activity: Neutralizes free radicals and reduces oxidative stress at the cellular level, making it one of the most potent natural antioxidants available for formulation.
- Antimicrobial properties: Demonstrated inhibitory effects against a range of pathogenic bacteria, supporting its use as a natural preservative in food systems.
- Lipid regulation: Associated with beneficial effects on blood lipid profiles, including support for healthy cholesterol and triglyceride levels.
- Anti-tumor activity: Research suggests polyphenols may inhibit the proliferation of certain cancer cell lines, though these findings are subject to ongoing clinical investigation.
- Liver protection: Helps protect hepatic tissue from oxidative damage, including damage associated with alcohol consumption.
- Immune modulation: Supports immunological function through antioxidant and anti-inflammatory pathways.
- Heavy metal chelation: Capable of binding and neutralizing certain heavy metal ions, which is of relevance in both food safety and therapeutic applications.
Industry Applications:
- Food & Beverage: Used as a natural antioxidant preservative and color-retention agent in processed food products, functional beverages, and health foods.
- Cosmetics & Personal Care: Incorporated into skincare formulations as an antioxidant, skin-brightening agent, UV-protective additive, and anti-radiation ingredient.
- Pharmaceutical & Nutraceutical: Applied in finished dosage forms targeting lipid metabolism, bacterial infections, and cancer prevention support.
L-Epicatechin (90%–98%)
L-Epicatechin is a naturally occurring flavan-3-ol belonging to the catechin subclass of polyphenols. Isolated from green tea polyphenols, it appears as a white to off-white fine powder with excellent solubility in water and methanol.
Bioactive properties:
- Potent antioxidant activity, protecting cells and tissues against oxidative damage
- Anti-inflammatory action, reducing markers of systemic inflammation
- Antimicrobial effects, with demonstrated activity against select bacterial strains
- Cardiovascular support, with associations to reduced risk of heart disease and improved endothelial function
- Antitussive properties supporting respiratory health
- Potential role in reducing cancer risk through modulation of oxidative and inflammatory pathways
L-Epicatechin is widely used in premium dietary supplement formulations, particularly those targeting cardiovascular health, anti-aging, and athletic performance recovery.
Epigallocatechin Gallate — EGCG (60% / 90% / 98%)
EGCG, or Epigallocatechin Gallate, is the most abundant and pharmacologically active catechin in green tea. It is isolated from Green Tea Polyphenols through advanced chromatographic purification processes and is available at multiple standardized concentrations (60%, 90%, and 98%) to suit different formulation needs.
EGCG has been the subject of extensive scientific research and is recognized as one of the most bioactive natural compounds in the nutraceutical industry.
Pharmacological and functional properties:
- Antioxidant: Among the most potent free-radical scavengers known in plant-derived compounds
- Antiviral & Antibacterial: Inhibits viral replication and demonstrates activity against multiple bacterial species
- Anti-inflammatory: Suppresses pro-inflammatory cytokines and modulates inflammatory signaling pathways
- Antithrombotic: Reduces platelet aggregation, supporting cardiovascular health
- Anti-tumor: Shown in preclinical studies to inhibit tumor cell proliferation and angiogenesis
- Metabolic support: Associated with thermogenesis and fat oxidation, widely used in weight management formulations
EGCG 98% is the industry's gold-standard specification for high-potency supplement applications, including capsules, tablets, and functional powders. Lower concentration grades (60%, 90%) are suitable for food, beverage, and cosmetic formulations where lower active dosing is appropriate.
L-Theanine (10%–98%)
L-Theanine is a unique non-protein amino acid found almost exclusively in the leaves of Camellia sinensis. It appears as a white crystalline powder, freely soluble in water but insoluble in ethanol and diethyl ether. It is extracted from natural green tea leaves using water-based or enzymatic extraction processes.
L-Theanine has gained significant commercial momentum in recent years due to its well-documented effects on cognitive function and stress modulation — particularly its synergistic interaction with caffeine, which makes it a foundational ingredient in nootropic and focus-enhancement formulations.
Established and investigated functional benefits:
- Promotes a state of calm alertness without sedation
- Supports stress reduction and anxiety management by modulating neurotransmitter activity
- Improves sleep quality and promotes natural relaxation
- Enhances cognitive function, focus, and working memory
- Supports healthy blood pressure levels
- Boosts immune function, including stimulation of T-cell activity
- Reduces physical and mental fatigue
Available at standardization levels from 10% to 98%, L-Theanine powder from Extract Makers is suitable for standalone supplements, stacked nootropic formulas, functional beverages (including ready-to-drink teas and energy drinks), and sleep-support products.
