The short answer
Last updated July 2026
A supplement contract manufacturer blends, encapsulates or tablets, tests, and bottles dietary supplements that you sell under your own brand. In the US they must follow FDA cGMP rules for dietary supplements under 21 CFR Part 111. Private label minimums typically start around 1,000 to 5,000 bottles per SKU, and lead times usually run 8 to 16 weeks once ingredient sourcing and finished-product testing are included.
Why Suppliers
The supplement category punishes brands that pick the wrong manufacturer. Your label is what the FDA and your customer see, so if the powder in the capsule does not match the Supplement Facts panel, that is your problem, not the factory's. Yet most brands choose a contract manufacturer from a Google search and a phone call, without ever checking whether the facility is registered, whether it runs cGMP, or whether it will show you a certificate of analysis for each ingredient lot.
Suppliers is the AI sourcing agent that makes that search evidence-based. Describe what you want made, a capsule, a gummy, a powder, a liquid tincture, with the quantity you can commit to, and the agent shortlists supplement and nutraceutical contract manufacturers that fit. You get minimum order quantities, lead times, testing capability, and indicative quotes compared side by side, with identity verification, registry and customs cross-checks, surfaced certifications, and risk flags attached to every match. The agent suggests and ranks; you verify the evidence and choose.
cGMP status up front
Facility registration and cGMP and third-party certifications such as NSF are surfaced with each maker, so compliance is something you filter on rather than discover later.
Every dosage form
Capsules, tablets, gummies, powders, softgels, and liquids need different equipment. Say the format in your brief and only makers who run that line get shortlisted.
MOQs compared honestly
Minimums are shown per SKU across your shortlist, so you can find a maker whose starting run matches the inventory risk you can actually carry.
Testing capability visible
See which makers do in-house identity, potency, and contaminant testing, and which send it out, before you build a brand on their certificates of analysis.
Ingredient sourcing surfaced
Lead time is usually driven by raw ingredients, not the fill. Compare quoted production windows so a botanical with a long lead does not stall your launch.
Flat price, no commission
A predictable monthly fee in USD, with no percentage of your purchase order, so we have no reason to steer you to any particular manufacturer.
How it works
Describe, match, decide.

Review quotes, MOQs, and lead-times side by side, then run RFQ outreach and POs in one place. You stay in control.
Buyer's guide
What to know before you commit.
cGMP is the line between a brand and a liability
Dietary supplements sold in the US are regulated as food, and the manufacturer must follow the FDA's cGMP rules for dietary supplements in 21 CFR Part 111. That covers identity testing of incoming ingredients, batch records, and finished-product specifications.
Ask for the facility's FDA registration, ask whether it has been inspected, and ask for a third-party audit such as NSF or UL if you plan to sell into retail. A manufacturer that hesitates on any of those three questions has answered a different question.
What you can legally say on the label
Supplements can carry structure and function claims, for example that a product supports immune health, provided you can substantiate them and you print the standard FDA disclaimer that the statement has not been evaluated by the FDA.
You cannot claim a supplement treats, cures, or prevents a disease. That crosses into drug territory. If your formula contains an ingredient not marketed in the US before 1994, it may be a new dietary ingredient requiring notification to the FDA, and your manufacturer should tell you that before you print a single label.
Ask for the certificate of analysis before the quote
The certificate of analysis is the document that proves what is actually in the bottle: identity, potency, heavy metals, microbials. It is the single most useful thing to ask a prospective manufacturer for.
Request a redacted COA from a recent batch of a comparable product. You are not checking the numbers so much as checking that the paperwork exists, that it names a real lab, and that the specifications are tight. If a maker cannot produce one quickly, that is your answer.
Where the lead time really goes
Blending and encapsulating is fast. What takes the time is buying raw material, and then testing the finished lot. A common botanical can be weeks out; a specialty branded ingredient with its own supply agreement can be much longer.
When you compare quotes, compare the timeline in three parts: ingredient lead time, production, and release testing. Two manufacturers quoting twelve weeks can be doing completely different things with those weeks.
At a glance
Typical MOQs and lead times by supplement format.
| Format | Typical MOQ per SKU | Typical lead time | What drives the cost |
|---|---|---|---|
| Capsules (stock formula, private label) | 1,000 to 2,500 bottles | 8 to 12 weeks | Ingredient cost and bottle count |
| Tablets | 2,500 to 5,000 bottles | 10 to 14 weeks | Tooling for the tablet press |
| Gummies | 5,000 to 25,000 units | 12 to 20 weeks | Depositing setup, flavor, and stability |
| Powders (tubs or sachets) | 1,000 to 5,000 units | 8 to 14 weeks | Flavor system and packaging format |
| Softgels and liquids | 5,000 to 10,000 units | 12 to 18 weeks | Encapsulation runs and shelf-life testing |
Ranges are what supplement contract manufacturers commonly quote to new brands in the US and are meant for planning. Custom formulas, branded ingredients, and third-party certification all move these numbers. Your shortlist quotes are the ones to act on.
People also ask
The questions buyers actually search.
What is a supplement contract manufacturer?
A supplement contract manufacturer is an FDA-registered facility that formulates, blends, encapsulates, tests, and bottles dietary supplements for other brands. You own the brand and the label; they own the equipment, the cGMP quality systems, and the batch records that prove what is in each bottle.
How much does it cost to start a supplement brand?
The manufacturing run is usually the largest first check. A 1,000 bottle private label capsule run often lands in the low thousands of dollars, plus label design, testing, and packaging. Cost per bottle falls steeply with volume, so quote your SKU at several quantities before committing.
What is the minimum order quantity for private label supplements?
Most supplement contract manufacturers start private label capsules at 1,000 to 2,500 bottles per SKU. Gummies and softgels typically require far more, often 5,000 units or above, because the depositing and encapsulation equipment is expensive to set up for a short run.
Do supplement manufacturers need to be FDA approved?
The FDA does not approve dietary supplements or the facilities that make them before sale. It does require the facility to be registered and to follow cGMP rules in 21 CFR Part 111, and it inspects for compliance. Approval and registration are not the same thing.
What is the difference between private label and custom formulation supplements?
Private label puts your brand on the manufacturer's existing stock formula, which is faster and has a lower minimum. Custom formulation means a formula developed to your specification, which adds development cost, testing, and usually a larger minimum order, but gives you a product no competitor sells.
How long does it take to manufacture a supplement?
Expect 8 to 16 weeks for a typical private label run. Blending and encapsulation are quick; the calendar is consumed by sourcing raw ingredients and by finished-product release testing for identity, potency, heavy metals, and microbials.
FAQ
Common questions.
Yes. Dosage format decides which equipment a facility needs, so state it in your brief. The agent shortlists makers that run that line, whether it is gummies, softgels, capsules, tablets, powders, or liquids.
It surfaces registration and certification evidence, including cGMP and third-party marks such as NSF, alongside identity and registry checks, with sources shown. That reduces the search burden, but it is not an audit and you should confirm current status directly with the facility.
Yes. Ask for domestic manufacturing in your brief and the shortlist focuses on US facilities, which many brands prefer for shorter lead times, easier site visits, and a simpler compliance story on the label.
No. Pricing is a flat monthly fee in USD with no per-deal commission, so nothing in our model rewards steering you toward a larger run or a particular manufacturer.
