GMP for food supplements: what it proves, and what it does not
TS LAB d.o.o. is a contract manufacturer of dietary supplements in capsules in Komenda, Slovenia, and it states GMP certification for that site. This page explains what a supplements GMP certificate is, who issues it, and the four fields that make it checkable.
Is TS LAB GMP certified, and by whom?
TS LAB states GMP certification for its capsule production site at Obrtna cona Potok pri Komendi 14, 1218 Komenda, Slovenia. GMP, Good Manufacturing Practice, is a written set of production and quality control requirements covering the whole cycle, from incoming materials through processing, packaging and storage to release of the finished product.
There is no single EU GMP certificate for supplements
This is the misreading to correct first. In the EU a food supplement is a food, not a medicine, so the binding legal frame is Regulation (EC) 852/2004 on the hygiene of foodstuffs with mandatory HACCP, and Directive 2002/46/EC on food supplements. The pharmaceutical GMP of EudraLex Volume 4 does not apply to a supplement plant.
So who issues a GMP certificate?
A private certification body, against a chosen published standard. In this sector that is most often the Food Supplements Europe guideline for manufacturers of food supplements, or the EHPM Quality Guide, or an ISO 22000 based food safety management certification. In the United States the binding instrument is different again: the cGMP rule for dietary supplements, 21 CFR Part 111.
What the Food Supplements Europe scheme covers
Certification against that guideline looks at the management system, personnel and competence, equipment, product and process development, storage, transport, HACCP, stability studies, shelf life, document control, complaints, withdrawal and recall, internal audit, subcontractor control and laboratory requirements. That list is the reason the certificate is asked for more often than any other document.
What does it cover, and what does it not cover?
A GMP certificate is a statement about a site inside a defined scope. It is not product approval, and reading it as one is the single most common mistake in this category.
What it covers
The site, its processes and its quality system inside the certified scope: personnel qualification, equipment and premises, documented procedures, batch records, in process and release controls, stability and shelf life work, deviation handling, complaints, withdrawal and recall, subcontractor control and laboratory arrangements.
What it does not cover
Whether a given formula is legal in a given country, whether a health claim is permitted, whether a dose sits inside a national maximum, or whether a specific batch meets its specification. Batch level evidence is the Certificate of Analysis, not the GMP certificate. It also does not stand in for a retailer audit standard, because GMP for supplements is not benchmarked by the Global Food Safety Initiative.
Why do brand buyers ask for a GMP certificate first?
Because it is the document that separates a factory from a broker. In the buyer research, documents and compliance is the largest theme, and GMP is the document named most often inside it.
Amazon sellers
Check the current request in your seller account, including the marketplace, product and required submission route. An approved testing provider may need to supply evidence directly; a European GMP certificate does not automatically satisfy the request.
Pharmacy and pharmaceutical private label
EU pharmaceutical GMP is not legally required for a supplement, but these buyers ask for GMP at the level of the Food Supplements Europe guideline in the contract, because they have to show their own qualified person an equivalent level.
Practitioner and clinical channels
These buyers ask for GMP compliant formulation plus third party testing of the finished product, and they read the scope line on the certificate rather than the badge.
How do I verify a GMP certificate?
A GMP certificate is verifiable only if the issuer, the number, the scope and the expiry date are printed on it. Ask for all four in writing. Rows are added to this table as each value is confirmed for publication, and a row that is not confirmed is left out rather than guessed.

There is no public register for this one
Use the issuing body named on TS LAB’s current certificate for verification. Check its register where available, or contact that body directly with the certificate number and scope. A link behind a seal does not establish who issued the certificate.
What does TS LAB publish with your order?
A certificate answers for the site. An order is answered by batch documents. A Certificate of Analysis, or COA, is the laboratory result sheet for one production batch, read against the specification that batch was released to.

Where to read more
HACCP answers a different question from GMP, and the two are usually asked for together. Read the HACCP page next, and the page on ISO 22000, IFS Food and BRCGS if your channel is retail own brand.

Questions buyers ask about GMP
Is TS LAB GMP certified?
TS LAB states GMP certification for its capsule production site in Komenda, Slovenia. Ask for the certificate copy with your offer and read the four fields on it: the issuing body, the certificate number, the scope and the expiry date. Those four fields, not the badge, are what a buyer can check.
Is there an official EU GMP certificate for food supplements?
No. In the EU a food supplement is a food, so the binding requirement is food hygiene law with HACCP under Regulation (EC) 852/2004, not the pharmaceutical GMP of EudraLex Volume 4. GMP certificates for supplement plants are issued by private certification bodies against published guidelines, most commonly the Food Supplements Europe guideline.
Does a GMP certificate prove that my batch is correct?
No. GMP certification covers the site, its processes and its quality system. The evidence for an individual batch is the Certificate of Analysis for that batch, plus the specification it was released against.
Will your GMP certificate satisfy Amazon?
Not automatically. Requirements depend on the marketplace, product and current request in your seller account. Amazon may require evidence through an approved testing, inspection and certification provider. Share that request before ordering so the manufacturing evidence, testing and submission route can be checked against it.
Does a supplements GMP certificate satisfy a retailer audit?
No. GMP for food supplements is not benchmarked by the Global Food Safety Initiative, while IFS Food, BRCGS and FSSC 22000 are. If your channel is retail own brand, read the page on ISO 22000, IFS Food and BRCGS before anything else.
Can I audit the site myself instead?
Yes. Production is at a single address in Komenda, Slovenia, and an on site audit inside the European Union is cheaper and faster than an intercontinental one. Ask for an audit date together with your enquiry.
