Co-Packer Vetting & Onboarding

Start by defining your real requirements — dosage form, volumes, certifications, timeline, and budget — then build a shortlist of manufacturers with genuine experience in your specific category, not just a polished website. From there it's diligence: verifying cGMP status and certifications, checking references, and comparing MOQs, lead times, and pricing at your volumes. The 'right' manufacturer is the one that fits your brand's size and trajectory, which is exactly what an independent vetting process is built to surface.

A co-packer — short for contract packager, and often used interchangeably with contract manufacturer — is the facility that actually makes your product: blending or encapsulating the formula, filling, and packaging it to your specs. For most supplement brands the co-packer is the single most important vendor relationship you'll have, because they control quality, lead times, MOQs, and a large share of your cost of goods.

Look past the sales conversation. A qualified co-packer can show current cGMP compliance and third-party certifications, real experience with your dosage form and category, transparent documentation (specs, COAs, stability data), and references you can actually call. Vetting means verifying those claims rather than taking them at face value — which is exactly where an experienced second set of eyes pays for itself.

It varies widely by dosage form, ingredients, and the manufacturer's setup — anywhere from a few thousand units to much higher. The trap isn't a high MOQ itself; it's committing to a volume you can't sell through before it ages or ties up cash you need elsewhere. Good vetting matches the MOQ to a realistic forecast and your working capital, not to optimism.

Most early brands start with one to keep things simple and hit MOQs. As you scale, a second qualified source can reduce risk and give you negotiating leverage — but only once your volume justifies the added coordination. The right answer depends on your dosage forms, geography, and growth stage, which is part of what onboarding planning sorts out.

Onboarding is everything between 'we chose them' and 'we're running smoothly': finalizing specs and documentation, aligning on forecasts and lead times, setting up POs and payment terms, agreeing on quality and COA processes, and establishing the communication cadence that keeps production predictable. Done well, it prevents most of the misalignment that sours manufacturer relationships later.
