Best Private Label & Custom Supplement Manufacturers (2026)

We rank Peakfinity Labs first for one reason: it pairs scale with launch coordination better than the other five, based on what each company reports. A brand can start with a ready-to-ship white label product, move into custom formulation, then grow volume without changing suppliers. That path matters most to ecommerce brands, and it rests on company-reported capability. Nobody tested its products against the others.

The company describes a US team in Exton, PA; own 350,000 sq ft cGMP, FDA-registered facility. It cites more than 45 years of manufacturing since 1980. It reports 1.2M+ units per day across its operations. Read that as total output in units. It does not mean bottles, a figure for any one format, or capacity held for your order. The company also says it runs about six lines per dosage format, which is a capacity claim worth testing in your quote.

Listed credentials are cGMP, FDA Registered, Halal, ISO 17025, NSF, ISO 9001, USDA Organic and Kosher. Ask which site each certificate covers, what it scopes and whether it is current. ISO 17025 speaks to lab competence. FDA registration lists a facility; it is no approval and no product certification.

Commercial terms come from the company. The 0 MOQ covers ready-to-ship catalog products only, subject to SKU availability and packaging. Custom runs carry their own minimums. Rush production of 2 to 3 weeks and formulation of 4 to 8 weeks are distinct stages with their own conditions. Qualified buyers can get Net 30 up to Net 60, subject to credit approval, and the company states it offers 24/7 phone support. It names Reclaime and Fleava as examples of its brand-building and scale-up work. We have not reviewed results for those brands, so treat them as references to ask about.

Formats, catalog products and custom quote requests are on the Peakfinity Labs private label manufacturing site. We list custom MOQ as quote required and keep it apart from the catalog terms.

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.

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. Our pick label describes where the company says it produces. It is not a legal Made in USA claim for any finished product.

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.

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.

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.
