Looking for a private label supplement manufacturer in the USA? Compare the listings below for white label supplements and stock formulas. Use the country and state links to narrow your shortlist.
Every company on this page has at least one manufacturing or packaging facility on a public registry we check (NSF/ANSI 455-2, Health Canada or Informed Manufacturer), and its own website says it offers private label. The certification comes from the registry. The private label claim is the company’s own: we record it with a quote from its website and the date we checked, and we have not verified it.
Private label usually means selling a manufacturer’s existing (stock) formula under your own brand, which can be quicker to launch than a custom formula. Ask each manufacturer for its list of stock formulas, what you can change, and who owns the formula.

What is private label manufacturing for supplements?
In a private label arrangement, a brand sells a manufacturer’s existing formula under its own label. White label often describes the same stock-formula approach; the contract determines what can be changed and whether the formula is exclusive. Ask who owns the formula, who approves the label, and who handles complaints and recalls. FDA’s CGMP guidance covers manufacturing, packaging, labeling and holding responsibilities; outsourcing does not make those responsibilities disappear.
There is no single shelf life for every supplement. FDA’s dietary supplement CGMP guidance says an expiration date is not required by that rule, but a date used on a label should have supporting data. Ask for stability evidence for your formula in the proposed packaging and storage conditions; a manufacturing date alone does not tell you how long the product will meet its specifications.

Questions buyers ask
How do I choose a private label supplement manufacturer in the USA?+
Start with the USA list, check the exact facility and its certificate scope, and confirm white label supplements and stock formulas. Ask for the minimum order, first-run and reorder lead times, testing plan and an itemized quote. Website capabilities are company claims unless a separate registry basis is shown; confirm the proposed work directly.
What is the difference between private label and custom formulation?+
With private label, you sell a formula the manufacturer already makes under your brand; with custom formulation, the manufacturer develops or runs a formula specific to you. Private label is often quicker to launch; a custom formula gives you a product competitors can’t buy off the shelf. Ask who owns the formula in each case.
Do you verify that these companies offer private label?+
No. A company is listed here when one of its facilities is on a public registry we check and its own website says it offers private label. We keep the quote, the page and the date we checked, and show them on the company’s profile. The registry certification is checked by us; the claim is the company’s own, so confirm it with the manufacturer before you rely on it.
What should I ask for in a quote request?+
Ask for minimum order quantity, lead times, formulation options, testing and certificates of analysis, in writing. In detail: ask about minimum order quantity (MOQ) per SKU, lead time for a first run and for reorders, whether they offer stock formulas or custom formulation, who sources raw materials, what testing they run (identity, potency, microbiological, heavy metals) and whether you receive a certificate of analysis (COA) per batch, and whether they support the label claims you plan to make. Terms vary widely by manufacturer, so compare written answers rather than assumptions.
How do I verify a manufacturer’s GMP certification myself?+
Ask the manufacturer for their current certificate and the exact facility address it covers, then look that facility up on the certifier’s public listing (for NSF/ANSI 455, NSF’s online listings). Certificates apply to specific sites, so make sure the facility that will make your product is the one listed. Each profile here links to the public listing we checked and the date we checked it.
