Navigating Regulation (EU) 2022/2340: Green Tea Extract Compliance
The complete compliance reference for the EU 800 mg EGCG daily limits
If your brand sells — or plans to sell — food supplements or functional foods containing green tea extract into the European Union, Regulation (EU) 2022/2340 is now binding law. It is not a guideline. It is not a recommendation. It is an enforceable amendment to Annex III of Regulation (EC) No 1925/2006 that places green tea extracts containing EGCG on the EU's restricted substances list — with legally mandated dosing limits and a set of mandatory label warnings that must appear on every product in the supply chain.
This article is a procurement and compliance reference for sourcing managers, regulatory affairs teams, and OEM formulators navigating this regulation. It covers the full regulatory text, EFSA's scientific rationale, serving size calculation methodology, mandatory label copy, compliant vs. non-compliant formulation comparison, and the strategic ingredient alternatives — including degalloylated green tea extract — that allow brands to retain high polyphenol content while avoiding the EGCG restriction entirely.
Commission Regulation (EU) 2022/2340, published 1 December 2022 and in force from 21 December 2022, amended Annex III to Regulation (EC) No 1925/2006 to place green tea extracts containing EGCG in Part B (Restricted Substances). The regulation mandates: (1) a maximum of less than 800 mg EGCG per daily portion of food or food supplement; (2) the label must state the EGCG content per portion and the maximum number of daily portions; (3) labels must carry four mandatory warning statements regarding the 800 mg daily cap, cumulative green tea product consumption, vulnerable populations (pregnant/lactating women and children under 18), and empty stomach avoidance. Full enforcement applies since 21 June 2023.

1. Regulatory Timeline: From EFSA Opinion to Binding Law
2. Annex III Structure: Part B, Part C, and the Novel Food Carve-Out
Annex III to Regulation (EC) No 1925/2006 has three parts: Part A (Prohibited); Part B (Restricted — may be added only under specified conditions); Part C (Under Union scrutiny — permitted but subject to ongoing review). Regulation (EU) 2022/2340 placed green tea extracts containing EGCG simultaneously in Part B (restricted, with 800 mg/day limit) AND Part C (under scrutiny at any dosage). This dual placement means EGCG-containing green tea extracts face both an immediate dosing restriction and ongoing regulatory review that may result in further tightening by December 2026.
| Annex III Part | Classification | What It Means for GTE with EGCG | Current Status |
|---|---|---|---|
| Part A | Prohibited Substances | Cannot be added to food under any circumstances | GTE with EGCG is NOT in Part A currently |
| Part B | Restricted Substances | May be added only under specified conditions: <800 mg EGCG/daily portion; mandatory label requirements; usage restrictions for vulnerable groups and fasting consumption | GTE with EGCG IS in Part B — binding restriction since 21 Dec 2022 |
| Part C | Substances Under Union Scrutiny | Permitted at any dosage but under active regulatory review; Commission must decide Part A/B status by ~Dec 2026 | GTE with EGCG IS in Part C — ongoing scrutiny at all dosage levels |
Table 1 — Annex III Classification of Green Tea Extracts Containing EGCG
The Novel Food Carve-Out — Highly Purified EGCG (≥90%)
Recital 17 of Regulation (EU) 2022/2340 explicitly states that the regulation does not affect the use of highly purified EGCG isolates (≥90% EGCG) authorized as a novel food under Regulation (EU) 2015/2283 and Commission Implementing Regulation (EU) 2017/2470. This creates a two-track system:
| Ingredient Type | Governing Regulation | EGCG Limit | Label Requirements | Procurement Note |
|---|---|---|---|---|
| Standard GTE (e.g., 40–80% EGCG) | Regulation (EU) 2022/2340 → Annex III Part B/C | <800 mg EGCG per daily portion | All four mandatory warnings; EGCG mg/portion; max daily portions | Must verify EGCG content per serving from batch-specific HPLC COA every lot |
| Highly purified EGCG isolate (≥90%) — Novel Food | Regulation (EU) 2017/2470 (Novel Food); NOT covered by 2022/2340 | Subject to Novel Food authorization conditions — separate limits apply | Novel food label requirements; must be authorized for specific use category | Requires confirmed Novel Food authorization scope for your specific food category — consult EU regulatory counsel |
| Traditional green tea infusion / RTD equivalent | Excluded from 2022/2340 — traditional food presumption | No cap | Standard food labeling only | Must contain ≥120 mg dry mass of tea extract per 100 mL to qualify as equivalent to traditional green tea infusion |
Table 2 — Three-Track Regulatory Framework for EGCG in the EU Market
The Commission has until approximately December 2026 to reclassify GTE with EGCG to either Part A (prohibited) or maintain/modify Part B. A reclassification to Part A would render EGCG-containing green tea extracts completely prohibited — triggering full product reformulation across the entire EU market. Brands building long-term EU strategies around high-EGCG extracts should consult EU regulatory counsel and monitor this decision timeline actively.
3. The Mandatory Label Requirements — Exact Regulatory Text
The following requirements are legally mandatory for all food supplements and food products containing green tea extracts with EGCG sold in the EU. They are not optional and cannot be modified or abbreviated. They must appear in the language(s) of the country of sale.
Restricted Substance: Green tea extracts containing (−)-epigallocatechin-3-gallate
Condition of Use: Daily portion of food shall contain less than 800 mg of (−)-epigallocatechin-3-gallate.
Additional Requirements — Label Must Include:
1. The maximum number of portions of the food for daily consumption AND a warning not to consume a daily amount of 800 mg of (−)-epigallocatechin-3-gallate or more.
2. The content of (−)-epigallocatechin-3-gallate per portion of the food.
3. The following warning statements (exact wording):
— "Should not be consumed if you are consuming other products containing green tea on the same day."
— "Should not be consumed by pregnant or lactating women and children below 18 years old."
— "Should not be consumed on an empty stomach."
| Requirement | What It Means in Practice | Common Compliance Error |
|---|---|---|
| "Daily portion shall contain less than 800 mg EGCG" | EGCG content per recommended daily dose must be less than 800 mg. Calculated from the HPLC-verified EGCG content of the specific ingredient batch — not from a generic product specification. | Calculating from nominal EGCG % on product spec sheet instead of actual batch HPLC result; not accounting for batch variation |
| "Maximum number of daily portions stated on label" | If the product has multiple servings per container, the label must explicitly state the maximum number of servings that may be consumed per day. Cannot simply say "take as directed." | Missing explicit "do not exceed X capsules per day" statement; relying on a suggested serving without a defined daily maximum |
| "EGCG content per portion stated on label" | The exact EGCG content in milligrams per serving must appear on the label — expressed as EGCG specifically, not as total catechins or total polyphenols. | Stating "X mg green tea extract" or "X mg catechins" without specifying EGCG mg content per serving |
| Green tea cumulative warning | Must warn against consuming other green tea products on the same day — brewed tea, other supplements, RTD teas. Addresses cumulative EGCG exposure from multiple sources. | Warning missing; present in English but not in local language for market of sale |
| Vulnerable population warning | Must explicitly warn pregnant AND lactating women AND children under 18 not to consume the product. | Warning present for pregnant women but missing "lactating women" or "children below 18 years old" |
| Empty stomach warning | Must warn against consumption on an empty stomach. Reflects EFSA's finding that fasting-state EGCG intake increases hepatotoxicity risk. | Warning missing; present on English version but absent from local language version in the market of sale |
Table 3 — Mandatory Label Requirement Interpretation for EU-Market GTE Products
Since 21 June 2023, non-compliant GTE products in the EU market are subject to enforcement action by national food safety authorities. Germany's BfR and enforcement agencies (LGL, LMUI) have been among the strictest. Online marketplaces including Amazon EU have begun requiring proof of EU compliance documentation for GTE products. A missing warning label, an incomplete EGCG per-serving declaration, or a serving size that calculates above 800 mg EGCG per day are all grounds for enforcement action, product removal, and fines.
4. Serving Size Calculation: How to Stay Below 800 mg EGCG
The most common compliance error is using the wrong EGCG value as the basis for serving size calculation. The 800 mg limit applies to actual EGCG delivered per daily portion — calculated from the HPLC-verified EGCG content of the specific ingredient batch, not from a nominal product specification.
Step 2: Calculate EGCG per serving Product: 500 mg GTE capsule EGCG per capsule = 500 mg × 0.487 = 243.5 mg EGCG
Step 3: Calculate EGCG per maximum daily dose If maximum daily dose = 3 capsules: Daily EGCG = 243.5 mg × 3 = 730.5 mg → COMPLIANT (below 800 mg) ✓ If maximum daily dose = 4 capsules: Daily EGCG = 243.5 mg × 4 = 974 mg → NON-COMPLIANT ✗
Step 4: Account for batch variation (CRITICAL) Worst-case batch at upper tolerance of 55% EGCG: EGCG per capsule = 500 mg × 0.55 = 275 mg Daily EGCG at 3 capsules = 825 mg → NON-COMPLIANT ✗ → Must reduce to 2 capsules max, or reduce GTE per capsule
RECOMMENDATION: Design for ≤750 mg EGCG/day maximum at upper spec to accommodate batch variation across the full specification range
| GTE Grade | GTE per Capsule | EGCG per Capsule | Max Daily Capsules for <800 mg EGCG | EU Status |
|---|---|---|---|---|
| 25% EGCG (standard grade) | 500 mg | 125 mg EGCG | 6 capsules/day = 750 mg EGCG | Compliant — significant headroom |
| 40% EGCG (supplement grade) | 500 mg | 200 mg EGCG | 3 capsules/day = 600 mg EGCG | Compliant — practical for most formulations |
| 50% EGCG (high potency) | 500 mg | 250 mg EGCG | 3 capsules/day = 750 mg EGCG | Compliant — tight margin; batch variation monitoring required |
| 50% EGCG (high potency) | 600 mg | 300 mg EGCG | 2 capsules/day = 600 mg EGCG | Compliant — recommended at 600 mg capsule size |
| 70% EGCG (ultra-potency) | 500 mg | 350 mg EGCG | 2 capsules/day = 700 mg EGCG | Compliant — very tight margin; batch HPLC verification mandatory every lot |
Table 4 — EU 800 mg EGCG Daily Limit: Serving Size Calculations by GTE Grade. All calculations must use batch-specific HPLC values — not nominal specifications.
A product formulated to deliver 790 mg EGCG/day based on 50% EGCG will exceed 800 mg if a batch is assayed at 51%+. Suppliers with ±5% HPLC tolerance could deliver batches from 47.5% to 52.5% EGCG. At 52.5%, a product designed for 790 mg/day could deliver 827 mg/day — placing it in violation. Design for ≤750 mg EGCG/day based on the upper specification limit, or require your supplier to provide tighter batch-specific tolerances and independently re-test every incoming lot against the EU 800 mg threshold before production use.
5. Compliant vs. Non-Compliant Formulations: Side-by-Side Analysis
| Scenario | Formulation Details | Daily EGCG Delivery | Label Requirements Met? | EU Status |
|---|---|---|---|---|
| Scenario A — Non-Compliant (Common Legacy Format) | 600 mg GTE / capsule @ 50% EGCG; up to 4 capsules/day; no EGCG per serving stated; no mandatory warnings | 4 × 300 mg = 1,200 mg EGCG/day | No — no EGCG mg/serving; no maximum daily portion; all four warnings missing | Non-Compliant — prohibited since 21 June 2023 |
| Scenario B — Non-Compliant (Label-Only Fix — Insufficient) | Same formulation; added "do not exceed 2 capsules/day"; added some warnings but EGCG per serving not stated; warnings not in exact regulatory wording | 2 × 300 mg = 600 mg EGCG/day — within limit | Partial — EGCG mg/serving missing; warning wording not exact regulatory text; "children below 18" missing | Partially Compliant — label non-compliance; enforcement risk remains |
| Scenario C — Compliant (Reformulated) | 500 mg GTE / capsule @ 40% EGCG = 200 mg/capsule; maximum 3 capsules/day stated; EGCG per serving = 200 mg on label; all four mandatory warnings in exact regulatory wording | 3 × 200 mg = 600 mg EGCG/day | Yes — all requirements met | Compliant — 200 mg headroom below 800 mg limit |
| Scenario D — Fully Compliant (Degalloylated GTE) | 600 mg degalloylated GTE / capsule; high total polyphenols (EGC, EC, ECG); EGCG content <5%; no EGCG restriction applies; no mandatory EGCG warnings required | EGCG below regulation threshold — 2022/2340 restrictions do not apply | Standard food labeling only; no mandatory EGCG warnings; no EGCG per serving required | Fully Compliant — no EGCG restriction applies |
| Scenario E — Compliant (Ultra-Low EGCG GTE) | 500 mg GTE / capsule @ ≤10% EGCG = max 50 mg/capsule; high total catechins (EGC, ECG, EC); 4 capsules/day = 200 mg EGCG max | 4 × 50 mg = 200 mg EGCG/day — well within limit | Yes — all mandatory warnings still required (product still contains EGCG at any level); EGCG per serving stated | Compliant — wide dosing flexibility; warnings still required |

6. Compliant Ingredient Alternatives: Degalloylated GTE and Low-EGCG Extracts
For brands that want to avoid EGCG warning language entirely — particularly products targeting women's health, children's sports nutrition, or markets where hepatotoxicity warnings are commercially damaging — ingredient alternatives exist that deliver high polyphenol and antioxidant profiles without the EGCG restriction.
Three categories of green tea-derived ingredients can be used in EU food supplements without triggering Regulation (EU) 2022/2340 EGCG restrictions: (1) Degalloylated green tea extracts — enzymatic removal of the gallate group converts EGCG to EGC, retaining high total catechin and antioxidant content without EGCG; (2) Isolated non-EGCG catechins — EC, ECG, and EGC as individual isolates or blends, none of which are restricted under 2022/2340; (3) Aqueous green tea extracts consumed as traditional beverage equivalents — excluded from 2022/2340 if the reconstituted beverage contains ≥120 mg dry mass of tea extract per 100 mL, comparable to traditional green tea infusion.
| Alternative Ingredient | EGCG Status | Antioxidant / Polyphenol Retention | EU Regulatory Status | Key Limitation |
|---|---|---|---|---|
| Degalloylated Green Tea Extract | EGCG enzymatically converted to EGC; residual EGCG typically <5% | High total polyphenols retained; EGC, EC, ECG provide antioxidant, antiviral, and antibacterial properties; DPPH radical scavenging maintained | Not restricted under 2022/2340 — EGCG below actionable threshold | Reduced EGCG-specific bioactivity; health claims tied specifically to EGCG cannot be made; production process adds cost; limited qualified supplier availability |
| EGC (Epigallocatechin) Isolate | No EGCG — EGC is the degalloylated form of EGCG | Strong antioxidant; retains much of green tea polyphenol activity; lower antioxidant vs. EGCG at neutral/alkaline pH | Not restricted | Limited commercial availability as a pure isolate; less clinical research than EGCG; small sourcing pool |
| EC (Epicatechin) Isolate | No EGCG — structurally distinct catechin | Antioxidant, cardiovascular health research; lower potency per mg vs. EGCG but no restriction | Not restricted | Lower antioxidant power per mg vs. EGCG; premium cost; limited food-grade supplier pool |
| Instant Tea Extract (Aqueous / RTD Equivalent) | Contains EGCG at levels comparable to traditional green tea infusion when reconstituted | Comparable to traditional green tea infusion — 90–300 mg EGCG/day equivalent at normal consumption | Excluded from 2022/2340 if reconstituted beverage ≥120 mg dry extract per 100 mL | Only applicable for beverage applications — not food supplements, capsules, or tablets |
| Low-EGCG Standardized GTE (<10% EGCG) | Contains EGCG but at very low levels — 25–50 mg EGCG per 500 mg serving | High total catechins and polyphenols; antioxidant capacity maintained | Restricted by 2022/2340 — mandatory warnings still required at ANY EGCG level; but very wide dosing headroom | All four mandatory EGCG warnings still required — regulation applies to any GTE containing EGCG regardless of concentration |

Key Strategic Decision: Which Approach Is Right for Your Brand?
7. Sourcing Requirements: What Your Supplier Must Provide
Mandatory Supplier Documentation for EU Compliance
- Batch-specific HPLC COA with EGCG content (w/w): Actual EGCG percentage for each production lot by HPLC per USP <621> or equivalent validated method, calibrated to a certified reference standard (USP-1236700). This value is used for your 800 mg serving size calculation. A generic product COA without batch number is not acceptable.
- GCG (gallocatechin gallate) quantified separately: HPLC method must achieve Rs ≥ 2.0 resolution between EGCG and GCG peaks. GCG co-elution inflates EGCG values by 2–8%, creating a false compliance calculation. Request GCG % on every COA.
- Individual catechin profile (EGCG, ECG, EGC, EC): All four catechins individually quantified. Allows verification that EGCG % is correctly stated vs. total catechins.
- Inorganic arsenic speciation report: EU Regulation 2023/915 requires inorganic arsenic speciation (As³⁺ + As⁵⁺) by HPLC-ICP-MS per EN 16802:2016. Total arsenic alone does not suffice for EU compliance.
- EU MRL pesticide multi-residue panel: Minimum 200 analytes per GC-MS/MS + LC-MS/MS, tested against EU MRL limits per Regulation EC 396/2005 for Camellia sinensis. ISO 17025 accredited laboratory. Annual test minimum; per-batch for new crop lots.
- Botanical identity confirmation (Camellia sinensis): HPLC fingerprinting or DNA barcoding confirming species.
- GMP facility certificate: ISO 22000 or FSSC 22000 preferred for EU food supplement supply chain. HACCP documentation. Facility audit access available.
- Technical dossier for degalloylated GTE (if applicable): Full process documentation demonstrating the enzymatic degalloylation method, residual EGCG testing per batch, and confirmation the resulting ingredient does not trigger 2022/2340 restrictions.
Supplier Disqualification Triggers for EU-Market Supply
- Cannot provide batch-specific HPLC COA with EGCG % (not just total catechins or polyphenols)
- HPLC method cannot separate EGCG from GCG (no Rs ≥ 2.0 documentation)
- No EU MRL pesticide panel available — or panel is <30 analytes
- No inorganic arsenic speciation data available for EU-bound product
- Cannot provide facility audit documentation or GMP certificate for EU food supplement supply
- For degalloylated GTE: cannot provide process documentation and per-batch residual EGCG testing
- Batch-to-batch EGCG variation >±5% without process explanation — creates uncontrolled regulatory risk for serving size calculations
8. Member State Variations: Germany, Belgium, and National Stricter Limits
| Market | EGCG Limit | Additional National Requirements | Enforcement Strictness |
|---|---|---|---|
| EU-Wide (Baseline) | <800 mg EGCG / daily portion | Four mandatory label warnings per 2022/2340; EGCG mg/serving declared; maximum daily portions stated | Moderate — enforced by national authorities |
| Germany | <800 mg EGCG / daily portion (EU baseline) | BfR additionally recommends explicit hepatotoxicity warning language and a "take-with-meals" advisory; Germany's LGL and LMUI enforcement agencies are among the most active in the EU for supplement label enforcement | High — among strictest national enforcement in EU |
| Belgium | 300–400 mg EGCG / daily portion (national recommendation — stricter than EU baseline) | FASFC has maintained a national recommendation of 300–400 mg EGCG/day maximum for supplements, stricter than the EU-wide 800 mg cap. Products approaching the 800 mg limit may face additional Belgian authority scrutiny. | High — national limit is stricter than EU baseline |
| France | <800 mg EGCG / daily portion (EU baseline) | ANSES food supplement reporting system; products may require notification to authorities depending on category | Moderate |
| Netherlands | <800 mg EGCG / daily portion (EU baseline) | NVWA enforcement; product notification required for food supplements before market placement | Moderate |
| Sweden / Norway / Denmark | <800 mg EGCG / daily portion (EU/EEA baseline) | Original petitioners for the regulation; health authority scrutiny elevated; Norway/Iceland apply EEA-equivalent rules | High — countries that initiated the regulation; elevated scrutiny |
Table 7 — Member State Variations in Green Tea Extract / EGCG Compliance. Consult local regulatory counsel for current national requirements in each target market.
9. EU Importer Compliance Checklist
Ingredient Sourcing Compliance
- Obtain batch-specific HPLC COA from supplier showing EGCG % for every production lot — not total polyphenols or catechins
- Confirm HPLC method separates EGCG and GCG with Rs ≥ 2.0; request GCG % separately on COA
- Calculate maximum EGCG delivery per daily serving using the upper range of batch COA EGCG values — not the nominal specification
- Confirm calculation result is <800 mg EGCG/day at maximum daily dose — with ≥50 mg safety margin below the limit to accommodate batch variation
- Obtain EU MRL pesticide multi-residue panel (≥200 analytes, ISO 17025 lab) for every batch or at minimum for each new crop year lot
- Obtain inorganic arsenic speciation data (HPLC-ICP-MS, LOQ ≤0.02 ppm) per EU Regulation 2023/915
- Confirm GMP facility certificate valid and applicable to EU food supplement supply chain
- For degalloylated GTE: obtain process documentation and per-batch residual EGCG testing confirming restriction does not apply
Label Compliance
- EGCG content per serving stated in mg on label — as "(−)-epigallocatechin-3-gallate: X mg per portion"
- Maximum number of daily portions explicitly stated — "Do not exceed X capsules/tablets/servings per day"
- Warning against exceeding 800 mg EGCG/day included in label text
- Exact mandatory warning in local language: "Should not be consumed if you are consuming other products containing green tea on the same day"
- Exact mandatory warning in local language: "Should not be consumed by pregnant or lactating women and children below 18 years old"
- Exact mandatory warning in local language: "Should not be consumed on an empty stomach"
- All warnings present in the correct language for each EU member state market where the product is sold
- Label reviewed by EU regulatory counsel or qualified food law specialist before product launch
Ongoing Compliance Monitoring

10. Frequently Asked Questions
Yes. EU food law applies based on where the product is consumed (placed on the EU market), not where the seller is located. A supplement sold online from the UK, US, or any non-EU country to an EU consumer is considered "placed on the EU market" and is subject to EU food law including Regulation (EU) 2022/2340. EU customs authorities and national food safety agencies can and do enforce compliance on imported products. This is particularly relevant for brands using cross-border e-commerce platforms — all mandatory label requirements and the 800 mg/day EGCG limit apply.
Legally, yes — 799 mg is below 800 mg and within the literal regulatory text. However, this is not a recommended formulation target. Given batch-to-batch EGCG variation of ±5% (standard specification tolerance), a product designed to deliver 799 mg could regularly deliver 830–840 mg from higher-EGCG batches. We recommend designing for a maximum of ≤750 mg EGCG/day calculated at the upper bound of your ingredient specification to ensure all batches remain compliant. Additionally, Belgium's national guidance recommends 300–400 mg EGCG/day — a product at 799 mg may face Belgian authority scrutiny.
The 800 mg limit applies exclusively to EGCG (epigallocatechin-3-gallate) — not to total catechins or total polyphenols. A product with 30% EGCG content (HPLC-verified against USP-1236700) and a 500 mg capsule delivers 150 mg EGCG per capsule. The daily limit is met when cumulative EGCG from all recommended daily capsules stays below 800 mg. Total catechin content is irrelevant to the EGCG calculation. This is why all EU-market ingredient COAs must specify EGCG percentage separately from total catechins.
Yes. Regulation (EU) 2022/2340 places green tea extracts containing EGCG in Annex III Part C "at any dosage" — meaning the product is under Union scrutiny regardless of EGCG level. The COT (UK Committee on Toxicology) confirmed that the regulation requires warning labels on all foods containing EGCG at any level. The EGCG per serving declaration, maximum daily portions statement, and all four mandatory warning texts are required even for products delivering very low EGCG amounts. This is precisely why degalloylated green tea extract — with EGCG below detectable levels — is commercially attractive for brands wanting to avoid all mandatory warning language.
Degalloylated green tea extract is produced by enzymatic hydrolysis of the gallate ester bond in EGCG (and ECG), converting these gallated catechins to their degalloylated forms — EGC (from EGCG) and EC (from ECG) — while releasing gallic acid as a co-product. The resulting extract contains EGC, EC, gallic acid, and other polyphenols, but essentially no EGCG. Because Regulation (EU) 2022/2340 specifically targets green tea extracts containing EGCG, degalloylated extracts with negligible residual EGCG (<5%) fall outside the regulation's scope. Antioxidant capacity is largely retained through EGC and EC. The production process requires qualified suppliers with documented enzymatic degalloylation processes and per-batch residual EGCG testing.
A reclassification to Part A would mean adding EGCG-containing green tea extracts to food — including food supplements — would be completely prohibited in the EU. Every EU-market product containing GTE with EGCG would need to be reformulated or withdrawn. This outcome is not certain — it requires a Commission decision supported by EFSA safety data submitted during the Part C scrutiny period. However, brands should treat this as a material regulatory risk for long-term EU product strategy. The most resilient approach is to build formulations that remain compliant under both the current Part B restriction and a potential future stricter scenario — lower EGCG per serving, or degalloylated alternatives that are not affected by any future EGCG-specific prohibition.
