What's Included in a Private Label Supplement Starter Kit? A Founder's Checklist

Most "starter kit" pages on competitor sites stop at "formula + label + bottle" and skip the four line items that actually determine whether you launch on time: the COA, the FBA carton spec, the claims review, and the fulfillment routing. This guide is the full checklist — what's in the kit, what isn't, what each line costs at a 2,000-unit MOQ, and the exact timeline from contract to shelf.

A private label supplement starter kit is the full bundle of components and services a contract manufacturer ships with your first production run of a single SKU. It's not a sample box. It's not a discounted trial. It's the operational package that takes you from "contract signed" to "first bottle on a shelf, with compliance documents in hand and a path to restock."

The reason the term matters is that the supplement industry uses "starter kit" loosely. Some dropship platforms call a stock SKU plus a Shopify integration a starter kit. Some manufacturers use it to describe a sample pack of stock formulas. What a founder actually needs — and what this guide defines — is the full launch bundle for a real branded, owned-inventory private label run. For the broader context on which manufacturing model fits your stage, see our dropship vs private label vs custom comparison.

Print this. Walk it line by line with any manufacturer you're evaluating. If a line item gets a vague answer or a "we'll figure that out later," that's the signal.

• Stock formula locked. Active(s), dose, capsule/tablet/gummy/powder format, fill weight, excipients, vegetarian/gelatin choice.
• Supplement Facts panel. Drafted by manufacturer from the locked formula. You approve before label artwork.
• Print-ready label artwork. Your design, in the manufacturer's dieline, with bleed, fold, and barcode positions correct.
• Primary packaging. Bottle, cap, induction seal, desiccant, cotton coil, fill quantity per bottle.
• Secondary packaging. Carton or shrink wrap. Required for some retail channels; optional but trust-building for DTC.
• Batch-level Certificate of Analysis. ISO 17025–accredited lab. Identity, potency, heavy metals (USP <232>), microbial.
• FDA facility registration and cGMP cert. The manufacturer's, on file and shareable on request.
• DSHEA claims and allergen review. Structure/function claims, "Other Ingredients" disclosure, allergen statements.
• FNSKU labels (for FBA). Amazon-specific barcode, printed and applied at the manufacturer.
• Expiration date and lot number. Printed on every bottle. Required for FBA and best-practice for any channel.
• Case-pack and master carton spec. Units per case, cases per pallet — required for FBA, retail, and 3PL receiving.
• Shipper carton labels. Amazon FBA shipment ID, carton ID, weight, and routing labels for direct-to-FBA shipments.
• Fulfillment routing. Where the finished goods ship to — FBA fulfillment center, your 3PL, or your warehouse.
• Product liability insurance binder. $1M–$2M minimum, listing the manufacturer as additional insured.
• Reorder spec sheet. The full bill of materials, packaging spec, and dieline locked for fast 14–21 day restocks.

Every private label starter kit begins with a stock formula your manufacturer has already produced, tested, and stabilized at scale. You're not paying for R&D — you're paying for a known-good formula with your brand on it. Peakfinity Labs runs a catalog of 50+ ready stock formulas across capsules, tablets, gummies, softgels, powders, stick packs, and liquid drops, plus 163+ in-house ingredients you can compose into a near-custom starter SKU without a full custom R&D cycle.

The Supplement Facts panel comes off the locked formula. Your manufacturer drafts it; you approve it; it goes on the label. Common founder mistakes here include negotiating doses after the panel is drafted (forces a redraft and pushes the label cycle), or trying to make claims the stock formula's substantiation doesn't support. Lock the formula first, draft the panel second, design the label third — in that order.

Manufacturers don't print a Canva PNG. They print from a vector PDF that lands inside their dieline — the exact dimensions, bleed, fold lines, and reserved positions for the Supplement Facts panel, barcode, lot/expiration print zone, and any required warning text. Peakfinity sends the dieline with every quote; the founder (or the founder's designer) supplies the visual design.

• Dieline format: Vector PDF or AI file, CMYK color mode, 300 DPI minimum on any embedded raster.
• Bleed and safe zone: 1/8 inch bleed standard, 1/8 inch safe zone inside the trim — text inside the safe zone, background to the bleed line.
• Supplement Facts panel placement: Manufacturer-specified position; do not move it.
• Barcode: UPC or EAN, 100% scale, on a high-contrast background. FNSKU is separately applied for FBA.
• Lot and expiration print zone: Reserved unprinted area where the manufacturer's printer lays down lot and exp at fill.
• Required text: Brand name and address (distributor of record), DSHEA disclaimer, "Keep out of reach of children," storage instructions.

Each round of label revisions adds 5–7 days to the timeline. Most launches lose more days to label cycles than to anything else — the fix is hiring a designer who has shipped supplement labels before, or asking your manufacturer for a recommendation.

Primary packaging is everything that touches the product. Secondary packaging is the carton or shrink that touches the bottle. Tertiary packaging is the shipper carton and pallet. All three are part of the starter kit.

The compliance document set is the part of the starter kit most founders don't know to ask for — and the part that determines whether your Amazon listing stays live, whether your retail buyer takes the meeting, and whether your future acquirer can run diligence in days instead of months. Peakfinity Labs bundles the full set with every production run.

• FDA facility registration number — the manufacturer's, confirming the production facility is registered under the Bioterrorism Act.
• cGMP certificate — confirming the facility operates under 21 CFR Part 111 dietary supplement Good Manufacturing Practices.
• Batch-level Certificate of Analysis — separate full section below.
• Identity and potency testing — confirms the actives in the bottle match the Supplement Facts panel.
• Heavy-metal testing — USP <232> limits for arsenic, cadmium, lead, mercury.
• Microbial testing — total plate count, yeast, mold, E. coli, salmonella, staph.
• Allergen disclosure — the eight major FDA allergens (plus sesame) declared or screened.
• DSHEA structure/function claims review — every claim on the label vetted against substantiation in the formula.
• Master Manufacturing Record (MMR) and Batch Production Record (BPR) — internal manufacturer documents; available to founders on request.

The full Peakfinity certifications register lists every accreditation under one page — useful to link from your /quality page once you launch.

The COA is the single highest-leverage line item in the entire starter kit. It's the document that proves the bottle on the shelf matches the label on the bottle. It's also the document Amazon's compliance team, retail buyers, and informed consumers ask for first.

A real COA includes:

• Lab name and accreditation (ISO 17025 minimum; AOAC validated methods are a plus).
• Sample identification — product name, batch/lot number, manufacture date, expiration date.
• Identity testing — HPLC, FTIR, or another validated method confirming the active matches the label.
• Potency / assay results — actual milligram or microgram content per serving, with method and tolerance.
• Heavy-metal results — arsenic, cadmium, lead, mercury, each against USP <232> limit.
• Microbial results — total plate count, yeast, mold, E. coli, salmonella, staph, against USP <2021>/<2022> limits.
• Pass/fail signature from the lab's quality officer.

The starter kit doesn't end at finished goods on the manufacturer's dock. Where the goods go next — and how cleanly they get there — determines whether your launch slips a week or hits the date. Three routes:

• Direct to Amazon FBA. Requires FNSKU labels, expiration and lot printing, poly-bag where applicable, manufacturer-applied case-pack, and shipment ID labels on every carton. Peakfinity's in-house 3PL ships private label runs direct to FBA with all four handled at the facility — see our Amazon FBA supplement manufacturing program for full FBA-ready spec.
• Your 3PL. Requires routing labels, BOL paperwork, and a receiving appointment at the 3PL. We coordinate this directly with founders' existing 3PL partners.
• Your warehouse. Requires shipping spec (LTL freight, residential vs commercial address, lift gate if needed) and a receiving plan.

Restock fulfillment is dramatically faster than first runs in all three routes — Peakfinity's in-house 3PL keeps domestic restocks at 14–21 days once the artwork, dieline, packaging, and routing are locked.

Setting expectations correctly is half the value of this guide. The following are not part of a standard private label starter kit and either need to be sourced separately or built in-house:

• Brand strategy, logo, or visual identity. Bring your own brand. Manufacturers don't design brands.
• Product photography for your PDP. The manufacturer can ship sample bottles for your photographer; the photoshoot is on you.
• Shopify, Amazon, or TikTok Shop storefront setup. The kit lands physical inventory; channel setup is separate.
• Paid acquisition or content strategy. Out of scope; cover this in your launch plan.
• Custom formulation R&D. Private label uses stock formulas. If you need a fully custom formula, see our custom formulation guide.
• Trademark and entity formation. File your LLC and trademark in week 1; both must exist before finished goods ship.
• Insurance. Product liability is your responsibility; manufacturer is named as additional insured.
• Customer support and returns. The manufacturer ships to your fulfillment node; post-purchase customer experience is your operation.

Representative numbers for a 60-capsule, single-active SKU at a 2,000-unit MOQ. Real-world figures vary by format, ingredient cost, packaging spec, and FBA prep complexity — always ask a manufacturer for a project-specific quote.

Powders and gummies push COGS up; capsules and tablets keep COGS lean. The biggest swing factors are packaging (custom cartons add setup fees) and FBA prep (poly-bagged, expiration-required SKUs are more labor than a simple case-pack).

The fastest path from contract to shelf is 4 weeks (stock formula, stock packaging, print-ready label on day one, FBA shipment plan ready in week 4). The slow path is 8–10 weeks (custom carton, three rounds of label revisions, new bottle SKU). Restocks run 14–21 days once everything is locked.

Every Peakfinity Labs 2,000-unit private label run ships with the full kit bundled — no upsells, no surprise compliance fees, no separate quote for the COA.

• Stock formula from a catalog of 50+ ready SKUs across capsules, tablets, gummies, softgels, powders, stick packs, and liquid drops.
• 163+ in-house ingredients for near-custom starter SKUs without a full custom R&D cycle.
• Supplement Facts panel drafted by our regulatory team from the locked formula.
• Dieline delivered with the quote; label artwork review included.
• Primary and secondary packaging — bottle, cap, induction seal, label, optional carton.
• Batch-level COA from an ISO 17025–accredited lab, included at no extra cost.
• FDA registration and cGMP certificate on file, shareable on request.
• DSHEA claims and allergen review on every label.
• FBA-ready labeling — FNSKU, expiration, lot, case-pack — applied at the facility.
• Direct-to-FBA shipping via our in-house 3PL in Exton, PA.
• 4–6 week first-run timeline; 14–21 day restocks.
• Prototype cost credited back against the first production run.
• One facility, one paper trail across private label, custom, and 3PL — 375,000+ sq ft, FDA-registered, cGMP, at 252 Welsh Pool Rd, Exton, PA 19341.

• Designing the label before the formula is locked. Every dose change forces a Supplement Facts redraft and a label revision — typically 7–10 days lost per cycle.
• Skipping the COA to save $200–$400. The COA is the single highest-ROI line item in the kit. Skipping it costs more in lost listings and PDP conversion than it ever saves on testing.
• Buying a low-MOQ run from a manufacturer that doesn't bundle compliance docs. The unit cost looks low until you spend three weeks chasing down an FDA registration number for a retail buyer.
• Forgetting FBA prep budget. FNSKU labels, poly-bag, expiration print, and case-pack add $1,000–$2,500 on a first run. Budget for it; don't be surprised by it.
• Not specifying a reorder spec sheet. Restocks should be 14–21 days. Without a locked spec, they're 30–45 days while everyone re-derives the bill of materials.
• Splitting manufacturing and 3PL across two vendors on the first run. Each handoff is a slip risk. In-house 3PL (Peakfinity model) collapses two SLAs into one.
