Getting started
What exactly do you manufacture?
Dietary supplements in capsules, tablets and powder form, made and packed in our own factory in Komenda, Slovenia. We lead with capsules and we promise on capsules, packed into jars, into blisters on two pharma quality blister lines, and into packs built for an Amazon listing. Tablets and powders are made here too, on our own tableting and powder filling lines, with tablets in jars and powders in jars, pouches and sticks. Softgels are made here too, on our own production, and are packed in jars only. Gummies and liquids are not part of our published range, so ask and we will tell you in the first reply whether we can source them or not.
Are you the factory, or do you subcontract production?
How fast do I get a price?
TS LAB states a written offer within 1 to 3 business days of receiving your formulation or idea, your target market and your preferred format. That offer states pricing, timelines, packaging options and the minimum order quantity for your product. Read that as time to offer, not as time to product.
What does TS LAB actually do?
TS LAB d.o.o. is a contract manufacturer of dietary supplements in capsules in Komenda, Slovenia. We fill, pack, release and ship capsules made to your formula and under your brand, from our own factory at one address inside the European Union.
How do I start, and what happens after I write?
What do you need in the first email?
The ingredients and the dose per daily serving, the pack you want, the quantity range you are planning and the markets you sell in. If the product already exists, add the current label and the latest batch certificate of analysis, and the answer gets a lot more exact.
Can you take over a product I already sell?
Do I have to be a big brand to work with you?
No, but every product has a minimum batch size, and for a small first run that number decides whether the project makes sense. The minimum for your product is in your offer, in writing, which is faster than guessing from a page.
Capsules
Do you make anything other than capsules?
Yes. We lead with capsules and we promise on capsules, in jars, in blisters and in packs built for marketplaces. Tablets and powders are made here too, on our own tableting and powder filling lines, with tablets in jars and powders in jars, pouches and sticks. Softgels are made here too, on our own production, and are packed in jars only. Gummies and liquids are not part of our published range, so ask and we will tell you in the first reply whether we can source them or not.
How do you decide which capsule size my formula needs?
It is a density question, not a milligram question. The same dose fills a different volume depending on the raw material and the blend, so the blend decides the fill weight, the fill weight decides the capsule size, and the capsule size decides the jar and the carton.
How much active can one capsule hold?
It depends on the bulk density of your blend and on the excipients, not on the label dose alone. If the daily dose does not fit one capsule it becomes two per serving, which changes the pack, the price per day and the shelf presence, so it is worth checking before the artwork is set.
Are your capsules suitable for a vegan product?
Can you pack capsules in blisters as well as jars?
Yes. TS LAB states two pharmaceutical quality blister lines alongside its packaging lines, and blisters and jars are two different production routes chosen at specification, not a finishing decision at the end.
Can you supply filled capsules in bulk, without packing them?
Yes. For brands and contract packers with their own packing lines, we fill the capsules and supply them in bags, quoted per 1,000 capsules, with the batch documents agreed for your order. Your line packs and labels them. See bulk capsules.
Quality and documents
What is a certificate of analysis?
Does a GMP certificate prove that my batch is correct?
No. GMP certification covers the site, its processes and its quality system. Evidence for an individual batch is the certificate of analysis for that batch, plus the specification it was released against.
Is there an official European Union GMP certificate for food supplements?
No. In the European Union 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.
Is HACCP mandatory or voluntary?
The HACCP based procedure itself is mandatory for every food business operator in the European Union under Regulation (EC) 852/2004. Certification of that system by an external body is voluntary, and TS LAB states HACCP certification by Bureau Veritas.
Is TS LAB FDA approved?
No, and neither is any supplement manufacturer. The FDA does not approve dietary supplements or the facilities that make them. TS LAB states an FDA registered facility, which is a filing requirement under 21 CFR Part 1 Subpart H, and the FDA states that a registration number does not convey approval or endorsement of a facility or its products.
Do you hold IFS Food, BRCGS, ISO 22000 or FSSC 22000?
No. TS LAB states GMP, HACCP certified by Bureau Veritas, organic handling, FDA facility registration and V-CERT vegan certification. IFS Food and BRCGS are retailer driven standards normally required for supplying supermarket and drugstore own brands, and for direct to consumer, marketplace, distributor and practitioner channels the tested expectation is GMP, HACCP and documented traceability.
Can I check your organic certificate myself?
Yes, and this is the easiest of the five to verify. Organic handling is certified by KON-CERT Maribor under Regulation (EU) 2018/848, and the Slovenian Ministry of Agriculture runs a public search where a certificate can be found by certificate number or operator name and the document downloaded.
Can you make a health claim for my ingredient?
Pricing and MOQ
Why is there no price list on this site?
Because a price per capsule that is true for one project is false for the next one. The same capsule count can differ by a multiple depending on the purity of the active, the fill weight, the shell, the pack and the batch size. Your price comes in the written offer, within 1 to 3 business days of receiving your product details.
What drives the price of a capsule supplement the most?
What is MOQ and why does it exist?
MOQ, the minimum order quantity, is the smallest batch a given product can be produced in. It exists because a batch has fixed costs that do not shrink: line setup, cleaning between products, quality control and documentation are the same work for a small batch as for a large one.
Why can I be charged for raw material I did not use?
Because raw materials also have minimum order quantities. If the smallest quantity a supplier sells is larger than your batch needs, someone pays for the surplus. We tell you when that happens and whether moving up one batch tier costs you less than paying for material you leave behind.
What is overage?
Overage is the extra quantity of an active dosed above the label value so that the product still meets its label claim at the end of its shelf life. Some actives lose potency over time and need more of it, which is the honest reason two offers for the same label text can differ.
What is your minimum order quantity in units?
Logistics and markets
Where do you produce and ship from?
From one address, Obrtna cona Potok pri Komendi 14, 1218 Komenda, Slovenia. Production, packing, release and dispatch all happen at that site, inside the European Union.
How long does production take?
Which markets can you supply?
Can you handle the notification of my product in my market?
Can you run a rush reorder if a campaign sells out my stock?
Do you hold safety stock of packaging for repeat orders?
What forecast do you need from me to reserve capacity?
Can I sell the product on Amazon?
Working together
Who owns the formula we develop together?
Ask before you pay anything, with us or with anyone. Formula ownership belongs in the written agreement and not in the small print, and it is one of the questions we expect you to ask on the first call.
Can I visit the factory?
Yes. One production address inside the European Union means a customer audit is a short trip rather than an intercontinental project. Write to us with the dates that suit you and what you want to see.
Why are there no customer names or logos on this site?
Because we do not have written consent to publish them yet. A manufacturer's client list is the client's business, not ours, and inventing logos or testimonials is exactly the behaviour this site exists to avoid. Named references and case studies will be published as customers agree to them.
How do I know you will still be here in two years?
Look the company up. TS LAB, proizvodnja prehranskih dopolnil, d.o.o., registration number 6038573000, registered in Slovenia on 10 October 2011, credit rating AA+ for 2026 in the Companywall register, active, with no blocked accounts and no insolvency proceedings.
What happens if a batch does not match the sample I approved?
That is what the specification and the batch certificate of analysis are for. The batch is released against the specification you approved, and the certificate of analysis for the batch is the evidence you can put in front of a retailer, a platform or a laboratory.
What kind of project is not a fit for you?
Gummies and liquids, because they are not part of our published range. Ask and we will tell you in the first reply whether we can source them or not. Capsules, softgels, tablets and powders are all made here, and we lead with capsules. IFS Food and BRCGS are not listed in the materials reviewed for this website. If your buyer requires one, request confirmation of the current certified scope before proceeding.
Which certificates does TS LAB state?
Five marks, each with the body behind it where the body is known, each on its own page with what it covers and what it does not cover. A badge without an issuer is worth nothing, so the issuer is named on the page, not only on the tile.
FDA registration is a filing, not FDA approval.
