Manufacturer profiles

Best overall for a stock-formula launch

Makers Nutrition

Makers Nutrition states that stock formulas can start at 500 units. That figure gives a first-time brand a known floor before the first sales call. The company lists capsules, gummies, liquids, powders, softgels and tablets, and it pairs production with label and design support.

Operations sit in Commack, New York, with packaging in Hauppauge, New York. The certifications page lists 2026 NSF GMP Manufacturing, GMP for Sport, GRMA conformance, FDA-registered facilities, USDA Organic and halal facility registration. Treat these as facility credentials the company publishes. They do not mean every product carries a sport certification or an organic seal.

Sources: Makers Nutrition private label page · Makers Nutrition certifications page

Strengths

  • A published 500-unit entry point for stock formulas
  • Label and packaging support for brands without an in-house designer
  • Wide format range, so a second SKU may not need a second supplier

Tradeoffs

  • Other brands can sell the same stock formula, so exclusivity is limited
  • Custom formula MOQ and schedule need a written quote
  • No published lead time; ingredient origin may vary by SKU

Ask before you sign

  • Which stock formulas qualify for the 500-unit minimum, and in which packaging?
  • Which facility credentials apply to the line that will run my SKU?
  • What is the dated schedule from label approval to finished goods release?

US-production shortlist

Vitalpax

Vitalpax identifies a production campus in La Verkin, Utah, and says it makes capsules, tablets, powders, stick packs and liquids there. Softgels also appear in its range. Ask where those run before you assume the same site.

The company states cGMP compliance, USDA Organic, Halal and Kosher credentials, and it posts a certificate page. We use the label US-production shortlist for this pick. It describes where the company says it produces. It is not a legal Made in USA claim for any finished product.

Sources: Vitalpax contract manufacturing page · Vitalpax certifications page

Strengths

  • Specific production location named on the company's own site
  • Several formats, including stick packs
  • A public certificate page you can check against the quote

Tradeoffs

  • No published batch minimum
  • No published lead time
  • Origin and any partner-facility use must be confirmed per SKU

Ask before you sign

  • What is the batch minimum for my format and fill size?
  • Will every step for my SKU happen at La Verkin? If not, where?
  • Can you give a dated schedule with milestones in writing?

Best for large-retail programs

Vitaquest

Vitaquest dates to 1977 and works from West Caldwell, New Jersey. It reports more than 4,000 custom formulas for more than 500 brands. Its listed formats are capsules, powders, tablets, chewables and effervescent tablets. Gummies do not appear in the reviewed sources.

The quality page documents cGMP, NSF, authorization to make NSF Certified for Sport products, organic certification through QAI, and Kosher and Halal. A separate company article adds FSSC 22000, NSF/ANSI 455-2 and USP. These are company-published credentials. Confirm which ones cover your product.

Sources: Vitaquest homepage · Vitaquest quality page · Vitaquest audit-ready article

Strengths

  • Long record of custom development across many brands
  • Extensive published quality documentation
  • Effervescent and chewable formats few suppliers list

Tradeoffs

  • Startup-size quantities should not be assumed
  • A stock catalog should not be assumed
  • No published MOQ or lead time

Ask before you sign

  • What first-order size makes a custom project viable for you?
  • Which credentials apply to my format and production line?
  • What retailer documentation packages can you supply with each lot?

Gummy-development shortlist

SMP Nutra

SMP Nutra offers custom gummy shapes and flavors alongside stock gummies. Its gummy page states stock gummies from 1,000 bottles and custom runs of 500,000 to 1,000,000 pieces. Its FAQ gives different numbers: stock at 2,500 to 5,000 bottles per SKU, and custom gummies at 600,000 to 1,000,000 pieces, or 10,000 to 16,000 bottles. The same FAQ also mentions a 1,000-bottle floor elsewhere.

SMP publishes conflicting minimums. Get a SKU-specific written quote. The FAQ gives conditional timing: 8 to 10 weeks for new customers, counted from label receipt, and 6 to 8 weeks for reorders when labels are already in house. The company states FDA registration and GMP and NSF claims.

Sources: SMP Nutra custom gummy page · SMP Nutra FAQ

Strengths

  • Custom gummy shape and flavor development
  • Published schedule with the condition that starts the clock
  • Covers gummies plus five other formats

Tradeoffs

  • Published minimums conflict across pages
  • Custom gummies require large runs
  • Gummies may need temperature-controlled freight in warm months

Ask before you sign

  • What is the written minimum for my exact SKU, count and bottle?
  • Does the 8 to 10 week window include stability and release testing?
  • What shipping conditions do you recommend for my gummy in summer?

Best for published capsule and powder planning ranges

NutraScience Labs

NutraScience Labs posts format-specific planning ranges. Capsules, tablets and powders start at 1,500 to 2,000 bottles depending on the formula. Softgels require 500,000 capsules. Lead times run 6 to 8 weeks for tablets and capsules and 10 to 12 weeks for custom powders.

The FAQ states the company does not make gummies, liquids, topical cosmetics or bars. The reviewed sources showed no current certification evidence, and the guide does not rely on third-party lists. Source note: the coordinating research agent's direct fetch of the FAQ returned a server error, so these figures come from the search-index copy of the official page. Reconfirm every term with the company.

Sources: NutraScience Labs FAQ (indexed text)

Strengths

  • Format-specific MOQ ranges you can use in a cash plan
  • Published lead times by format
  • Clear statement of formats it does not make

Tradeoffs

  • Custom quantities tie up inventory and cash
  • No gummy or liquid service per the indexed FAQ
  • Request certification evidence from the company

Ask before you sign

  • Is my project stock private label or custom manufacturing, and how do the terms differ?
  • Can you send current certificates with scope and expiry dates?
  • Do the FAQ ranges still apply today?

Publisher pick for scale and ecommerce brands

Peakfinity Labs

Publisher-selected entry. Facts below come from Peakfinity Labs and have not been verified by anyone outside the company.

Peakfinity Labs publishes this guide. We selected it ourselves, and the facts below come from the company, not from independent checks. Its US team works from Exton, Pennsylvania. The company cites family manufacturing history since 1980, more than 45 years, and describes “our own 350,000 sq ft cGMP, FDA-registered facility.” It reports capacity of 1.2M+ units per day. That figure counts units, not bottles, and it is total capacity, not capacity reserved for you.

The company lists cGMP, FDA Registered, Halal, ISO 17025, NSF, ISO 9001, USDA Organic and Kosher. ISO 17025 covers laboratory competence. FDA registration is neither a certification nor a product approval. The 0 MOQ covers ready-to-ship catalog products and excludes custom runs; availability and packaging still need a quote. Custom runs carry their own minimum, so ask for a quote. Rush production of 2 to 3 weeks and formulation of 4 to 8 weeks are separate stages, not a promise of end-to-end delivery. Qualified buyers may get Net 30 up to Net 60 terms.

Company details, including the custom-minimum terms its homepage mentions, appear on the Peakfinity Labs website. We list custom MOQ as quote required and keep it apart from the catalog terms above.

Strengths

  • US commercial team
  • Stated scale plus a catalog entry path
  • Net 30 to Net 60 terms for qualified buyers

Tradeoffs

  • An Exton team does not establish US manufacturing origin
  • Confirm production country, import duties, freight and landed cost
  • Confirm batch MOQ and certificate scope for your SKU

Ask before you sign

  • In which country will my SKU be produced and packed?
  • What is the custom batch MOQ for my format, and the landed cost to my warehouse?
  • Which certificates cover the facility and lab handling my SKU, and when do they expire?

How to decide

Start with format. If your product is a gummy, two of six suppliers drop out. NutraScience Labs says it makes none, and Vitaquest lists none.

Then size your cash. Multiply the minimum by your unit cost and add testing and freight. A 500-unit stock run and a 600,000-piece gummy run belong to different businesses.

Decide how much exclusivity you need. Stock formulas get you to market sooner. Custom formulas protect you from a competitor with the same label copy.

Weigh origin on purpose. If your marketing or retailers demand domestic production, ask each supplier where your SKU runs. A US address on a website does not answer that.

Treat gaps as questions. Four of six suppliers publish no lead time we could rely on. Ask, and get the answer in writing with the event that starts the clock.

Shortlist three. Send each the same RFQ below. Compare landed cost per unit, release date and document quality side by side.

Apples-to-apples RFQ checklist

Send every supplier the same request. Quotes built on different assumptions cannot be compared. Track the answers in our quote worksheet.

  1. 1Formula, servings and pack count. Send the same ingredient list, serving size, servings per container and count to every supplier.
  2. 2Batch size. Quote at two volumes, such as your first order and a reorder, so price breaks are visible.
  3. 3Testing. List identity, potency, microbial and heavy metal tests, and who pays for each.
  4. 4Stability. Ask whether stability data exists for the formula or must be built, and at what cost.
  5. 5Packaging. Specify bottle, closure, desiccant, label size and case pack. Ask who sources each part.
  6. 6Incoterms. Name the term, such as EXW or DDP, so each quote stops at the same point.
  7. 7Origin. Request country of manufacture and packing in writing for the SKU.
  8. 8Freight. Ask for freight to your warehouse, with temperature control if the format needs it.
  9. 9Release milestone. Define release: finished goods with a passing COA, ready to ship.
  10. 10IP and exclusivity. Settle who owns the formula and whether the maker can sell it to others.

Methodology

We built this guide from desk research. A coordinating research agent checked each manufacturer's official pages on November 8, 2026, and supplied the cited facts. The editorial team wrote the guide from that research. We did not request quotes, order samples, visit factories, run lab tests or audit anyone.

We grouped the findings under five buyer priorities. The weights below suggest how a typical first-time buyer might rank them. We did not compute scores, and no supplier received a number.

  • 30%Quality and testing evidence. Published certificates, testing scope, and how specific the claims are.
  • 25%Format and formulation fit. Whether the supplier makes your format and supports stock or custom work.
  • 20%Order and cash commitment. Published minimums and the inventory they force you to fund.
  • 15%Schedule transparency. Whether timing is published, and what event starts the clock.
  • 10%Logistics and commercial support. Packaging help, payment terms, freight and location detail.

Each category pick reflects strengths and limits visible in published material. A missing figure lowers our confidence in a supplier's fit. It does not prove the supplier fails that test. Shift the weights to match your own needs.

We treat manufacturer claims as claims. A certificate the company lists differs from evidence an outside auditor confirmed for your product, so each profile tells you what to verify.

Peakfinity Labs owns this guide and appears in it. That conflict runs through every page, and we disclose it at the top of each one. The Peakfinity Labs editorial team wrote it as an organization. No named person and no independent reviewer has signed off.

Corrections. If a fact about a company is wrong or out of date, use the contact page on that company's own site, reached through the sources cited in its profile. Companies can send corrections the same way. We update entries when an official source changes.

Buyer questions

What is the difference between stock and custom private label?
Stock private label puts your label on a formula the maker already produces. Minimums are lower and launches move faster, but competitors can sell the same formula. Custom manufacturing builds a formula for you. Expect higher minimums, development time and stability work, in exchange for a product others cannot copy off a catalog.
Which manufacturer has the lowest MOQ, and what are the conditions?
Peakfinity Labs states 0 MOQ for ready-to-ship catalog products. That figure excludes custom runs. Makers Nutrition publishes 500 units for stock formulas. Both figures apply to stock or catalog items. Custom formulas at every company here need a written quote.
What does FDA registered mean? Is it the same as FDA approved?
No. Facility registration tells the FDA a site exists and what it handles. The FDA does not approve dietary supplements before sale, and registration says nothing about any product's quality.
How do I check certificate scope and a COA?
Ask for each certificate as a document. Check the certifying body, the facility address, the scope and the expiry date. A facility certificate does not cover every SKU. For each lot, request a certificate of analysis that lists identity, potency, microbial and heavy metal results, and the lab that ran them.
Which milestones should a production schedule include?
Ask for dates for formula sign-off, raw material arrival, label approval, production, testing, release and shipment. Many quoted lead times start at label receipt or material arrival, so confirm which event starts the clock.
Does a US sales team mean US-made products?
No. A US office tells you where the sales team works. Ask where blending, encapsulation, packaging and testing happen for your SKU, and get the country of origin in writing.
How should I compare landed costs and payment terms?
Add unit price, testing, packaging, duties, freight, insurance and warehousing to get a landed cost per unit. Then compare deposits and terms. Net 60 eases cash flow. A full landed cost shows the real price.
How do the category picks work, and what about the publisher's conflict?
Each pick names the best fit among these six for one buyer need, based on published material. They are not universal rankings or test results. Peakfinity Labs publishes this guide and appears in it, so read its entry as a self-description and verify it like any other.
