LOT / Batch Number Standard
Every Sheni Labs bottle carries a LOT number. This page explains exactly what each character means, why the format was chosen, and how to use it to trace a bottle to its full production record. We publish this because we believe transparency starts with the most basic element: knowing what is printed on your product.
THE FORMAT
SL‑D3‑202510‑001‑A
SL
Brand
Sheni Labs — every lot begins with SL, confirming the product is authentic Sheni Labs and not a third-party relabelling.
D3
Product code
Two-character product identifier. Unique per formulation — if the active ingredient changes, the code changes.
202510
Year + month
YYYYMM of manufacture. Lets you confirm the production month matches the expiry date shown on the label.
001
Batch sequence
Sequential number within that month. Resets to 001 each month. Allows multiple batches of the same product in one month.
A
Manufacturing site
Single letter identifying the certified EU facility that produced this batch. Different letters = different sites.
Product codes
| Code | Product | Active substance | Strength |
|---|---|---|---|
| D3 | Vitamin D3 | Cholecalciferol | 50 µg (2,000 IU) per drop |
| O3 | Omega-3 | EPA + DHA (algal oil) | Per label |
| VE | Vitamin E | d-alpha-tocopherol | Per label |
| AX | Astaxanthin | Astaxanthin (H. pluvialis) | Per label |
| Q0 | CoQ10 | Ubiquinol | Per label |
| K2 | Vitamin K2 | Menaquinone-7 (all-trans MK-7) | Per label |
| B2 | Vitamin B12 | Methylcobalamin | Per label |
| VA | Vitamin A | Retinyl palmitate | Per label |
Manufacturing site codes
The site letter in the LOT identifies the EU-certified manufacturing facility. Each facility has passed independent GMP (EU Annex 11), ISO 22000, and HACCP certification audits. The full facility documentation is available on each product’s certification page.
| Code | Country | Certifications |
|---|---|---|
| A | Poland (EU) | GMP EU Annex 11 · ISO 22000 · HACCP |
| B | Germany (EU) | GMP EU Annex 11 · ISO 22000 · HACCP |
| C | France (EU) | GMP EU Annex 11 · ISO 22000 · HACCP |
| D | Slovenia (EU) | GMP EU Annex 11 · ISO 22000 · HACCP |
What happens at each stage of a batch
The LOT number is the thread that connects every step below. Each step is documented. If any step fails specification, the batch is rejected and never receives a LOT number for public release.
LOT LIFECYCLE
1
Raw material receipt and identity testingActive ingredient (e.g. cholecalciferol) received from supplier. Identity confirmed by UV/HPLC against Ph.Eur. reference standard. Heavy metals tested. Supplier CoA reviewed. Batch quarantined until passed.
2
Carrier / excipient testingMCT oil (Miglyol® 812 N) tested for peroxide value, acid value, and identity. Confirms oxidation status before blending. Any out-of-spec carrier rejects the whole batch.
3
Blending and fillingActive is weighed and blended into carrier under controlled conditions (temperature, light exclusion). Filled into amber glass bottles in a certified facility. The LOT number is assigned at this stage to the specific production run.
4
In-process and finished product potencySamples taken and tested by the facility’s in-house laboratory. Active content measured per drop. Specification: 90–110% of label claim. This is the “identity / potency” document on the verification page.
5
Independent laboratory testing (third-party)A separate sample from the same batch is sent to an ISO/IEC 17025-accredited external laboratory. Tests: identity, potency (HPLC), heavy metals (ICP-MS: Pb, As, Cd, Hg vs ICH Q3D), microbiology (TAMC, TYMC, E. coli, Salmonella, S. aureus vs Ph.Eur. 5.1.4). The resulting Certificate of Analysis (CoA) is the document you see on the verification page.
6
Release decisionThe Quality Control department reviews all test results. If all pass: batch released. If any fail: batch rejected (reworked or destroyed; rejection recorded in the batch record and reported in the Annual Transparency Report). The LOT number only appears on public-facing verification if the batch was released.
7
Labelling and packagingLOT number and expiry date (EXP) printed on the back label and bottle base. QR code generated and linked to this specific LOT’s verification record. Dropper assembled; food-contact compliance documents filed.
8
Transport and chain of custodyTemperature during transport logged and archived. Delivery receipt filed. LOT number used to match every consignment document. Enables identification of any bottle to its exact transport leg if a cold-chain issue were ever suspected.
9
Post-market: state registration (Georgia)Batch registered with the National Food Agency (სეს) as required by Georgian Food Code. State registration number on file. The LOT links the product sold in Georgia to its EU manufacturing record.
10
Public verification and batch record retentionLOT record published at shenilabs.ge/verify-your-batch/. Any consumer can verify their bottle anonymously, 24/7. Batch records retained for a minimum of 5 years after the expiry date. All batch data (lots released, any out-of-spec events, complaints, recalls) published annually in the Georgian Medical Journal (DOI 10.66636).
Why pharmaceutical-grade numbering?
Food supplements are legally foods, not medicines. No regulation requires us to use this level of batch traceability for a supplement. We do it because:
- A LOT number without a verifiable record is just ink on a label.
- Traceability is what makes a recall possible — and what makes one unnecessary if quality is consistent.
- Healthcare professionals and pharmacists expect this standard when recommending a product to patients.
- The WHO documents that falsified supplements regularly enter legitimate supply chains. Our verification system is a direct response to that risk.
- The Public Health Institute of Georgia (PHIG) operates Sheni Labs and is committed to the same evidence standards it applies in academic and clinical work.
Regulatory basis
| Jurisdiction | Requirement | Sheni Labs implementation |
|---|---|---|
| Georgia | Georgian Food Code Art. 16 — traceability; Resolution №360 — batch records | LOT system + public verification + PHIG annual report |
| European Union | Regulation (EC) 178/2002 Art. 18 — traceability one step back, one step forward; Directive 2011/91/EU — batch marking | LOT on every unit; manufacturer batch records; QR links to digital record |
| United States | 21 CFR Part 111 §111.260 — batch production records required for dietary supplements | Manufacturer’s batch record system; CoA per batch; digital verification layer |
