What is Green Tea Extract standardised for?

Green Tea Extract is standardised for its polyphenol and catechin fraction. Total polyphenols are measured by UV-Vis (grades from 50% up to 98%), while individual catechins — chiefly epigallocatechin gallate (EGCG) — are quantified by HPLC. SV Botanica supplies grades at 40–80% catechins and 30–50% EGCG. EGCG is the most studied marker compound and drives most of the extract's antioxidant and metabolic activity.

What part of the plant is used and which species?

The young leaves of Camellia sinensis (L.) Kuntze — the same plant used for all true teas. For green tea extract the leaves are steamed or pan-fired soon after harvest to deactivate the oxidising enzymes, which preserves the catechin profile that fermentation would otherwise convert to theaflavins. Leaves are sourced from Indian tea gardens (Assam, the Nilgiris, Darjeeling and Kangra) and extracted via a validated water/hydro-alcoholic system.

Does Green Tea Extract contain caffeine, and is a decaffeinated grade available?

Green tea leaf naturally contains caffeine, so standard extract grades retain a defined caffeine level (typically declared on the CoA). SV Botanica also supplies decaffeinated (≤0.5% caffeine) grades for clean-label, evening and caffeine-sensitive formulations, while maintaining the standardised polyphenol and EGCG content. Specify your caffeine target at the time of inquiry.

What is the recommended dose of Green Tea Extract in supplements?

Typical supplement servings provide 200–500 mg of standardised green tea extract, delivering a defined EGCG dose per the grade selected. Formulators should calculate the finished-product EGCG load and keep it within destination-market guidance — EFSA has flagged a hepatic-safety signal for EGCG intakes at or above 800 mg/day from supplements. Dose should be set against the standardisation grade and the finished-product claim.

Does SV Botanica supply an organic or decaffeinated Green Tea Extract?

Yes. Alongside conventional grades, SV Botanica supplies certified organic green tea extract and decaffeinated (≤0.5% caffeine) grades, with the standardised polyphenol/catechin content maintained. Organic certification and residual-solvent and caffeine results are documented on each CoA. Minimum order and lead times for organic and decaf grades may differ — please specify at inquiry.

What certifications and documentation does SV Botanica provide with Green Tea Extract?

Every batch ships with: Certificate of Analysis (CoA) — polyphenol assay by UV, catechin/EGCG assay by HPLC, caffeine content, moisture, heavy metals, microbiology, mesh size; MSDS; Allergen Declaration; BSE/TSE-free statement; Country of Origin Certificate; Non-GMO affidavit; Organic, Halal and Kosher certificates on request; Phytosanitary Certificate for export; FSSAI and APEDA documentation for Indian regulatory compliance.

How does Green Tea Extract compare to Green Coffee Bean Extract?

Both are polyphenol-rich metabolic and antioxidant ingredients, but their marker chemistry differs. Green Tea Extract is standardised for catechins (notably EGCG), associated with thermogenesis and fat oxidation. Green Coffee Bean Extract is standardised for chlorogenic acids (CGA), associated with glucose-handling and post-meal metabolic support. They are frequently combined in weight-management and energy formulations. See our green coffee vs green tea comparison for formulation guidance.

What is the shelf life and storage condition for bulk Green Tea Extract?

Bulk Green Tea Extract has a shelf life of 24–36 months from manufacture date when stored correctly: cool (≤25°C), dry (<60% RH), dark environment in sealed containers. Catechins are sensitive to heat, moisture and oxygen, so protection from humidity and light is important to preserve EGCG content. Product ships in 25 kg HDPE drums with a polyethylene inner liner to maintain integrity in transit.

Can Green Tea Extract be used in food and beverage products?

Yes. Water-soluble and granular grades are available for functional beverages, RTD teas, energy and metabolic shots, sports-nutrition mixes and effervescent tablets. The extract has a characteristic astringent, mildly bitter polyphenol profile. Food-grade batches are manufactured under FSSAI-licensed facilities and comply with the FSS (Health Supplements, Nutraceuticals…) Regulations, 2022; EGCG levels should be set against destination-market guidance.

What is Green Tea Extract?

The most extensively researched antioxidant polyphenol ingredient

Green Tea Extract is produced from the young leaves of Camellia sinensis — the same plant behind all true teas. What distinguishes green tea is the processing: leaves are steamed or pan-fired soon after harvest to deactivate the polyphenol-oxidase enzymes. This stops fermentation and locks in the native catechin profile that black and oolong teas largely convert to theaflavins.

The primary bioactives are catechins — a family of flavan-3-ol polyphenols dominated by epigallocatechin gallate (EGCG), alongside EGC, ECG and EC. Green tea leaf also naturally contains caffeine, the calming amino acid L-theanine, and flavonols such as quercetin and kaempferol. Total polyphenols are quantified by UV-Vis, while individual catechins and EGCG are measured by HPLC — these markers form the basis of every standardised grade.

SV Botanica sources green tea leaf from India's established tea-growing regions — Assam, the Nilgiris and Darjeeling, plus the high-grown gardens of Kangra — and extracts via a validated water/hydro-alcoholic system at controlled temperatures to protect the heat- and oxygen-sensitive catechins. The result is a clean, pale green to greenish-brown powder that disperses readily in formulations.

We supply antioxidant, weight-management and sports-nutrition brands, functional-beverage companies and contract formulators across Europe, the USA, Japan and Southeast Asia. Formulators weighing the two leading metabolic polyphenols can start with our green coffee vs green tea comparison.

Active Constituents

Key phytochemicals driving green tea's antioxidant profile

Total Polyphenols (Marker)

The headline antioxidant fraction, quantified by UV-Vis at 50%–98% across standardised grades. A family of flavan-3-ol catechins.

EGCG (Epigallocatechin gallate)

The most abundant and most-studied green tea catechin, and the reference compound for HPLC assay and biological activity.

Catechins (EGC, ECG, EC)

The wider catechin family contributing to total polyphenol load and the characteristic antioxidant fingerprint of the leaf.

Caffeine

Naturally present in tea leaf; retained at a defined level in standard grades and reduced in decaffeinated grades.

L-Theanine

A unique tea amino acid studied for its calming, focus-supporting effect — often paired with caffeine in cognitive formulas.

Flavonols & Tannins

Quercetin, kaempferol and condensed tannins that add to the extract's total polyphenol and free-radical-scavenging capacity.

Health Benefits & Research Backing

Evidence from clinical trials, systematic reviews, and mechanistic research

🔥

Thermogenesis & Fat Oxidation

A controlled study reported that green tea extract increased 24-hour energy expenditure and fat oxidation beyond what its caffeine content alone would explain, pointing to the catechins as the active fraction.

Ref: Dulloo AG et al., 1999; Am J Clin Nutr

⚖️

Weight Management Support

A meta-analysis of randomised trials found that catechin–caffeine mixtures produced a modest but significant effect on body weight and weight maintenance, supporting green tea's role in metabolic formulations.

Ref: Hursel R et al., 2009; Int J Obes

❤️

Cholesterol & Lipid Profile

A meta-analysis of controlled trials reported that green tea catechins significantly lowered total and LDL cholesterol, consistent with the polyphenols' role in cardiovascular support.

Ref: Zheng XX et al., 2011; Am J Clin Nutr

🛡

Antioxidant Capacity

Green tea catechins are potent dietary antioxidants, scavenging free radicals and supporting cellular defence. Green tea is one of the richest practical sources of these flavan-3-ol polyphenols.

Ref: Higdon JV & Frei B, 2003; Crit Rev Food Sci Nutr

🩺

Blood Pressure & Vascular Tone

A meta-analysis of randomised trials reported small but significant reductions in systolic and diastolic blood pressure with green tea intake, attributed in part to improved endothelial function.

Ref: Khalesi S et al., 2014; J Hypertens

🧠

Focus & Cognitive Support

The combination of L-theanine and caffeine native to green tea has been shown to improve attention and alertness in controlled studies, underpinning its use in nootropic and energy blends.

Ref: Owen GN et al., 2008; Nutr Neurosci

Responsible-marketing note: finished-product claims must be substantiated and compliant with each destination market's regulations. EFSA's 2018 assessment flagged a hepatic-safety signal for EGCG intakes at or above 800 mg/day from supplements, so formulators should calculate and declare the finished-product EGCG dose and keep it within applicable guidance.

Quality Assurance & Sourcing

From tea leaf to finished extract — traceable, tested, certified

Raw Material Sourcing: Green tea leaf is sourced under Good Agricultural and Collection Practices (GACP) from India's established tea regions — Assam, the Nilgiris, Darjeeling and the high-grown gardens of Kangra. Leaves are processed (steamed or pan-fired) soon after plucking to halt oxidation and preserve catechins. Botanical and grade authentication is performed by HPLC fingerprinting against reference standards before processing.

Manufacturing: Extraction is carried out in GMP-certified facilities (WHO-GMP and ISO 22000 audited) using validated water/hydro-alcoholic parameters at controlled temperatures to protect the heat- and oxygen-sensitive catechins. Each batch runs through a full QC battery — UV polyphenol assay, HPLC catechin/EGCG assay, caffeine determination, heavy-metals ICP-MS, pesticide-residue GC-MS/LC-MS, residual solvents, and a full microbiological panel — before release.

Documentation: Every shipment comes with Certificate of Analysis (CoA), MSDS, Allergen Declaration, BSE/TSE-free statement, Non-GMO affidavit, Country of Origin Certificate, and Phytosanitary Certificate. Organic, Halal and Kosher certificates are available for the appropriate grades.

Regulatory & Compliance Notes

Key information for global product registration and labelling

European Union

Green tea extract is used in EU food supplements; as tea (Camellia sinensis) has a long history of food use, conventional water/hydro-alcoholic extracts are generally not treated as Novel Food. Importantly, Regulation (EU) 2022/2340 sets conditions on catechins from green tea: products must stay below 800 mg EGCG/day and carry specified warnings. Confirm the extract specification and EGCG dose against current rules; labelling must comply with Regulation (EU) 1169/2011.

United States

Classified as a dietary ingredient under DSHEA (21 CFR Part 111). No pre-market approval required for dietary supplements. Facility registration under the FDA is required for importers. Structure-function claims are permissible with 30-day FDA notification and substantiation; antioxidant and weight-management claims must be carefully and credibly substantiated.

India & Other Markets

FSSAI-compliant for food-supplement use under the FSS (Health Supplements, Nutraceuticals) Regulations 2022. Accepted in Japan (often as a Foods with Function Claims ingredient subject to dossier), the Middle East (Halal grades), Southeast Asia, Australia (TGA), and Canada (NNHPD). Caffeine and EGCG content should be declared per destination-market rules.
