If you skim nothing else on this page, take this part.

Lowest realistic MOQ for a first SKU: NutraScience Labs. Capsule and powder runs starting at low-MOQ tiers for first-time founders, full-service from formula through finished goods, NSF and NPA GMP audited. The factory most often cited by Amazon-first sellers placing first POs.

Highest credibility at scale: Vitaquest. Fortune 500 and clinical-trial-grade clients on the public site, multiple GMP and certification stacks, full pharma-aware QA posture. Lead times stretch and minimums are real, but the audit trail is the cleanest in the category.

Specialty pick — gummies and full-service: Makers Nutrition. Strong gummy capability, in-house design and packaging services, multiple GMP certifications. The factory operators name when the format is gummy, soft chew, or stick pack.

Below: detailed entries on those three plus four others worth shortlisting depending on your category. Honest profiles. No "voted #1" claims. Every fact below sourced from each manufacturer's public website and verified against the issuing body where a certification is named.

Six axes, weighted in roughly this order for a founder placing a first or second PO.

1. Certification posture. FDA registration is the floor. Above that we look for current third-party GMP audit — NSF (NSF directory), NPA (NPA GMP program), UL, or equivalent — and category-specific certifications like NSF Certified for Sport, USDA Organic, or Halal/Kosher where relevant.
2. MOQ tier. First-run minimums for a typical capsule, powder, or gummy SKU. We grade against the realistic ranges in our MOQ guide — sub-1,000, 1,000-2,500, 2,500-5,000, or 5,000+.
3. Lead time transparency. Whether the public site quotes ranges (good), gives ranges with caveats (better), or hides lead time entirely (concerning).
4. Capability range. Format coverage — capsule, tablet, powder, gummy, liquid, soft chew, stick pack — and whether stock formula libraries are disclosed.
5. Transparency. Whether the public site publishes facility addresses, certification certificate numbers, leadership biographies, and reference clients. Opacity is a soft red flag at any volume tier.
6. Public client base. If a manufacturer publishes named brands, it tells you what categories the factory actually executes well — not just what they list on a capability deck.

What we did not do. We have not audited these facilities ourselves and we make no claim of first-hand vetting. Every entry below is sourced against each manufacturer's public website, the FDA registered facility database, and the certifying bodies' published directories where a certification is cited. We have placed POs in this category and these manufacturers are the names that recur. That is the basis for the shortlist — not a ranking metric, not a popularity score.

What's missing on purpose. Alibaba listings, broker resellers fronting unnamed factories, and "manufacturers" whose websites are stock-photo capability decks without facility detail. None of those clear the floor.

Headquarters: Farmingdale, New York. Public site: nutrasciencelabs.com.

Why founders shortlist them. NutraScience Labs is one of the most-cited names in private-label supplements at the entry-volume tier — the factory that comes up when an Amazon seller is placing a first 1,000-2,500 unit run. The public site documents capabilities across capsules, tablets, powders, gummies, liquids, and soft chews. The pitch on their public site is "low MOQ private label" and "full-service" — meaning formula, label design, packaging, and finished-goods fulfillment are all available under one engagement.

Certifications. The public site documents GMP registration, kosher and halal certification on applicable lines, and references to NSF and NPA audit posture. Cross-reference any certification against the issuing body's directory before signing — that's true for every entry on this page.

MOQ tier. Public messaging targets the lower end of the realistic supplement MOQ range. For a stock-formula capsule, expect to land in the 500-1,500 unit window. Custom-formulated runs and certain specialty formats sit higher.

Lead time. Public site quotes faster turnaround than typical for the category — the messaging targets the speed-sensitive Amazon and DTC founder. Realistic lead times still depend on whether you're using a stock formula or a custom one.

Capability range. Capsules, tablets, powders, gummies, soft chews, liquids. The breadth is what makes the factory a candidate for a brand planning multiple SKUs across formats.

Public client base. The site lists case studies and named brands. Read those carefully — they tell you which categories and formats the factory actually executes well versus what they list on a capability deck.

Strengths to lean on. Low entry MOQ. Full-service so a first-time founder doesn't have to coordinate label print, packaging, and fulfillment separately. Long-running brand, well-documented public posture.

Caveats to ask about. Verify the exclusivity posture on any "private label" SKU — the same question you ask any low-MOQ private label factory, covered in our private label vs white label brief. Confirm which line the certifications you care about actually run on.

Headquarters: West Caldwell, New Jersey. Public site: vitaquest.com.

Why founders shortlist them. Vitaquest is one of the largest private-label and contract supplement manufacturers in North America. The public site references multi-decade operating history, Fortune 500 and clinical-trial-grade client work, and a deeper QA stack than typical for the category. This is the manufacturer founders move to when a brand has scaled past the 10,000-unit-per-run window and needs an audit posture that survives a retailer or insurer review.

Certifications. The site documents NSF GMP registration, USDA Organic on applicable lines, kosher and halal capabilities, and a multi-stack QA program. The breadth of certifications means a brand can typically add a certification — Certified for Sport, Organic, Non-GMO Verified — without changing manufacturers.

MOQ tier. Higher than the entry-tier factories. Realistic first-run windows sit in the 2,500-10,000 unit range depending on format. The factory is not optimized for sub-1,000 unit founders; it's optimized for brands with retail commitments and ongoing reorder cadences.

Lead time. 10-22 weeks depending on format and certification asks. The longer end is real — this is a factory that runs validation and stability testing as standard, which extends timeline but produces an audit trail that holds up in a retailer or pharmacy review.

Capability range. Tablets, capsules, softgels (notable — softgel capability is rarer than capsule), powders, liquids, and certain functional-food formats. The softgel capability is one of the differentiators founders cite.

Public client base. The public site references Fortune 500 work and clinical-trial-grade engagements, though specific brand names are typically held under NDA at this volume tier.

Strengths to lean on. Audit posture. Capability across regulated and pharma-adjacent categories. Softgel capability if the format is on the table.

Caveats to ask about. MOQ floor is real. If your first run is sub-2,500 units, this is not the right shortlist — start at the entry tier and migrate to Vitaquest at the v2 reorder. Lead times stretch, particularly for custom formulation work; budget the calendar accordingly.

Headquarters: Hauppauge, New York. Public site: makersnutrition.com.

Why founders shortlist them. Makers Nutrition is the name that recurs when the format is gummy, soft chew, or stick pack — categories with higher tooling cost and tighter line economics than capsules. The public site documents in-house gummy production, full-service graphic design, packaging design, and label printing under one roof. For a founder launching a gummy SKU without an existing packaging studio, the integration matters.

Certifications. The public site references multiple GMP certifications, Informed Sport / Informed Choice posture on applicable lines, and a documented QA program. Verify each against the issuing body before signing.

MOQ tier. Mid-tier. Gummy MOQs are structurally higher than capsule MOQs across the industry — typical first-run gummy windows sit in the 1,000-2,500 unit range, and Makers fits that band. Capsule MOQs come in lower.

Lead time. Public site documents a faster turnaround than typical for gummy work. Realistic timelines for custom-formulated gummies still run 12-18 weeks once stability testing is added.

Capability range. Capsules, tablets, powders, gummies, liquids, soft chews, stick packs. The breadth across "harder" formats is the differentiator.

Public client base. The site features named brand case studies. Worth reading before a discovery call — they tell you which formats the factory actually ships at volume.

Strengths to lean on. Gummy capability. In-house packaging and label print. Full-service engagement for founders who don't want to coordinate three vendors.

Caveats to ask about. Pricing on full-service can be higher than coordinating vendors yourself once you have the relationships — appropriate for first runs, worth re-pricing on reorder. Verify the gummy stability program; gummy SKUs have unique stability concerns around hardening and color drift that don't apply to capsules.

Headquarters: Lindon, Utah. Public site: voxnutrition.com.

Why founders shortlist them. Vox Nutrition sits in the Utah supplement corridor — Salt Lake County and surrounding cities are home to one of the densest concentrations of supplement manufacturers in the U.S., a corridor that built up around early players in the category. Vox's public posture is "custom formulation at lower MOQs" — targeting founders who want a formula change but don't have the volume to justify a 5,000-unit minimum.

Certifications. The public site documents GMP registration and a working QA stack. Cross-reference certification claims against issuing body directories before signing.

MOQ tier. Lower than typical for custom formulation. Public messaging targets entry-tier founders with custom asks — a meaningful niche, because most factories make custom-formulated runs prohibitively expensive at low volume.

Lead time. Realistic custom-formulation lead times of 14-22 weeks once formulation, stability checkpoints, and label-claim validation are added.

Capability range. Capsules, tablets, powders, liquids, gummies. Breadth is moderate — appropriate for a brand with a clear category focus, less so for a brand planning across all formats.

Public client base. The site features case studies and testimonials. Worth verifying directly via reference call.

Strengths to lean on. Custom formulation at sub-large MOQs. Utah corridor proximity to ingredient suppliers and packaging vendors keeps the supply chain tight.

Caveats to ask about. "Custom" can mean different things at different price points — confirm what the formulation deliverable actually is, who owns the resulting formula document, and what the exclusivity posture is. The exclusivity question is covered in our private label vs white label brief.

Headquarters: Anaheim, California. Public site: superiorsupplementmfg.com.

Why founders shortlist them. Superior Supplement Manufacturing's public posture leads with NSF Certified for Sport capability — the certification that matters for any brand selling into professional sports, NCAA, military, or any retail channel that screens for banned substances. The NSF Certified for Sport program tests every batch against the WADA banned substance list. Few private-label factories run lines certified to that standard.

Certifications. The site documents NSF GMP registration and Certified for Sport program participation, alongside standard GMP audit posture. NSF Certified for Sport is the differentiator.

MOQ tier. Mid-tier. Sport-certification programs require dedicated line scheduling and per-batch testing, which pushes minimums above the entry-level tier — typical first-run Certified for Sport SKUs sit in the 2,500-5,000 unit window.

Lead time. Per-batch testing through NSF's program adds 2-4 weeks to standard lead times. Plan a 14-20 week launch window for a Certified for Sport SKU.

Capability range. Capsules, tablets, powders. Format breadth is narrower than the largest factories — focused capability rather than broad capability.

Public client base. The factory's reference brands cluster in performance, recovery, and clinical-grade categories.

Strengths to lean on. Certified for Sport. Performance category fit. California regulatory framework familiarity (Prop 65, MoCRA-adjacent).

Caveats to ask about. Sport certification per-batch costs are real and they don't go away — budget the recurring testing cost across the brand's lifetime, not just the launch run. Confirm whether a specific stock formula already holds the certification, or whether your run requires a new submission.

Headquarters: Hauppauge, New York. Public site: bactolac.com.

Why founders shortlist them. Bactolac Pharmaceutical operates with a pharma-adjacent posture — FDA-registered, NSF GMP-registered, with capabilities the public site documents around tablets, capsules, softgels, and powders. The factory comes up when a brand needs a manufacturer comfortable with regulatory-heavy categories — pediatric formulations, certain women's health categories, clinical-research-driven SKUs — where the audit trail and stability documentation matter more than the per-unit price.

Certifications. NSF GMP-registered, FDA-registered, public posture documents kosher and halal capability on applicable lines, and softgel-specific certifications.

MOQ tier. Higher tier. First-run windows typically sit in the 5,000-25,000 unit range. The factory is not built for entry-tier founders; it's built for brands with retail or institutional commitments.

Lead time. 12-22 weeks. Pharma-adjacent stability and validation programs are run as standard.

Capability range. Tablets, capsules, softgels, powders, liquids. Notable softgel and tablet capability — both formats have higher tooling cost than capsules and fewer factories run them at scale.

Public client base. Bactolac's reference clients cluster in regulated and pharma-adjacent categories, often under NDA.

Strengths to lean on. Audit posture. Tablet and softgel capability. Comfortable with regulatory-heavy categories most factories shy away from.

Caveats to ask about. Not the right factory for a sub-2,500-unit first run. Custom-formulation lead times can be long — confirm the timeline before locking a launch date.

Headquarters: Yorba Linda, California. Public site: nutralliance.com.

Why founders shortlist them. Nutralliance sits at the food-supplement crossover — a useful position for brands launching functional powders, RTD beverages, sachets, or stick packs that sit somewhere between a supplement and a food. The public site documents capabilities in dry-blending, sachet and stick-pack filling, and powder formats. For a functional-beverage or functional-food founder, the format-fit can matter more than a pure supplement factory's capability list.

Certifications. The public site documents GMP registration and a QA stack appropriate for both supplement and food-grade work. Verify each against the issuing body before signing.

MOQ tier. Mid to higher tier. Sachet and stick-pack formats have structurally higher minimums than capsules — typical first-run windows sit in the 5,000-25,000 unit range.

Lead time. 10-18 weeks depending on format and certification asks.

Capability range. Powders, sachets, stick packs, capsules, tablets, certain RTD beverage formats. The format breadth is genuinely useful for brands that don't fit a capsule-and-powder-only factory.

Public client base. Reference clients cluster in functional foods, sports nutrition, and beverage-adjacent categories.

Strengths to lean on. Sachet and stick-pack capability. Food-supplement crossover comfort. California regulatory familiarity.

Caveats to ask about. Confirm whether your specific format is run in-house or subcontracted — some sachet runs at this tier of factory are run via partner facilities. The distinction matters for audit-trail purposes.

A short list, because the exclusions are as instructive as the inclusions.

Alibaba and ThomasNet listings. Excluded across the board. Not because every overseas manufacturer is wrong — some are excellent — but because the platform listings don't surface the audit history a U.S.-bound supplement brand needs. Sourcing through Alibaba is a different process with different vetting steps; if your category and volume make overseas the right call, run a deeper diligence process than this listicle covers.

Brokerage operations fronting unnamed factories. Several brand-known names in the category are aggregators that subcontract production to unnamed partner facilities. Sometimes legitimate, sometimes not — but a "manufacturer" whose public site doesn't disclose the actual production facility is a transparency gap. Excluded.

Manufacturers without public certification verification. Several plausible-looking factories cite certifications on their public sites that don't appear in the issuing body's directory. Excluded by default. NSF, NPA, and ISO directories are public and free to search; if a claim doesn't survive a 30-second cross-reference, it doesn't make this list.

Pure white-label operators marketed as private label. Several entry-tier factories market themselves as "private label" but the SKUs they ship are stock formulas being relabeled — the formula is identical across all their buyers. That's white label at a private-label price point. Not excluded outright, but the operator should know what they're buying. Covered in detail in our private label vs white label brief.

If a manufacturer you expected to see isn't on this list, the most likely reason is a transparency or verification gap on the public materials. Email us a name and we'll look at it explicitly.

This is the decision tree we use when sourcing for clients. It's not the only frame, but it's the one that gets to a shortlist of two factories the fastest.

Step 1: define your category and format. Capsule, tablet, powder, gummy, soft chew, stick pack, liquid, softgel. The format usually eliminates half the shortlist immediately. A gummy SKU is not going to land at a factory that doesn't run gummies; a softgel SKU narrows to maybe a third of the names on this page.

Step 2: define your MOQ window. What's the launch budget? What's the projected sell-through velocity? A 500-unit founder is shopping NutraScience or Vox, not Vitaquest or Bactolac. A 25,000-unit founder is shopping Vitaquest or Bactolac, not the entry-tier names. Mismatching MOQ tier is the most common sourcing mistake we see.

Step 3: define your timeline. Need to be in market in 8 weeks? You're shopping stock-formula private label at the entry tier. Need to be in market in 22 weeks with a custom formula and stability data? You have the full shortlist available.

Step 4: define your certification asks. NSF Certified for Sport narrows the shortlist immediately — Superior, Vitaquest, and a handful of others run lines certified to the standard. USDA Organic, kosher, halal, vegan-only, and other category certifications each narrow further. Stack only the certifications your retail channels actually require — over-certifying at launch volume is margin you don't get back.

Step 5: send the same brief to three. Once the shortlist is two or three names, send identical briefs — format, fill, target retail price, certification asks, target launch date, projected first-run volume. The quotes that come back tell you who actually wants the work and who's quoting against capacity they don't have. The five-question vetting brief from our how-to-find-a-manufacturer brief is a useful structure for that vetting round.

Three of the seven factories above are appropriate for any given founder. Not all seven. The work of running the shortlist — sending the brief, scheduling the discovery calls, comparing the quotes against a single spec — is real and it takes 4-8 weeks if you do it yourself.

That's the work we do. Brief us once on format, fill, target retail, certification asks, and target launch date, and we come back inside 36 hours with three matched factories — MOQ, lead time, and indicative cost on each, all priced against the same spec so the comparison is real. We have placed POs across supplements, cosmetics, food & beverage, and pet care, and the candidates we surface are the ones we'd shortlist for our own brands.

If you'd rather have one point of contact across multiple manufacturers — particularly useful when you're running a multi-SKU launch where different formats want different factories — see our quote page. The brief takes about 8 minutes to fill out. The matched factories come back inside 36 hours.
