Supplement Manufacturing Glossary

Plain-English definitions of the terms buyers meet when sourcing private label supplements – dosage forms, factory processes, quality documents, certifications, and shipping. Written for brand owners and sourcing managers, not chemists.

Dosage Forms

Gummy

A chewable supplement delivered in a gelatin or pectin base. Pectin gummies are plant-based, which makes them suitable for vegan and halal markets; gelatin gummies have a firmer bite. Gummy manufacturing is heat-sensitive, so actives are dosed within a carrier that protects them during cooking. See our gummy manufacturing page.

Hard Capsule

A two-piece shell, usually gelatin or HPMC (plant cellulose), filled with powder, granules, or pellets. Most common format for herbal extracts and multivitamins. HPMC shells are the standard choice when a buyer needs vegan or halal-compatible capsules.

Softgel

A one-piece gelatin shell filled with liquid or paste. Used for oils, fat-soluble vitamins, and ingredients sensitive to oxygen. Softgels offer high absorption for oil-based actives but cannot carry large dry powder doses. See softgel manufacturing.

Tablet

A compressed dose form made by pressing powder blends under high pressure. Options include immediate release, chewable, effervescent, and enteric coating. Tablets suit high-volume, cost-sensitive products. See tablet manufacturing.

Effervescent Tablet

A tablet that dissolves in water and releases carbon dioxide, creating fizz. Common for vitamin C, electrolytes, and glutathione. Requires low-humidity production and moisture-barrier packaging, since the product will absorb ambient moisture.

Powder and Stick Pack

Dry blends sold in tubs, jars, or single-serve stick packs. Preferred for protein, creatine, pre-workout, and electrolyte formulas where the dose is measured in grams rather than milligrams. See powder manufacturing.

Liquid and Drops

Solutions, emulsions, or suspensions dosed by dropper or spoon. Liquids bypass the need to swallow a capsule, and are common for children and seniors. Stability and preservative systems matter more than in dry formats. See liquid manufacturing.

Energy Gel

A concentrated carbohydrate gel in a single-serve sachet, used during endurance activity. Typically formulated with maltodextrin or fructose blends plus electrolytes. See energy gel OEM.

Manufacturing and Sourcing

Private Label

Buying an existing, proven formula and putting your own brand on it. Fastest and cheapest route to market because formulation and stability work are already done. Best for testing demand before committing to custom development.

OEM (Original Equipment Manufacturer)

The factory builds a product to the buyer’s specification – your formula, your label, your packaging. You own the formulation, the factory owns the process. See OEM/ODM services.

ODM (Original Design Manufacturer)

The factory develops the formula and offers it to multiple brands, sometimes with exclusive rights. Lower development cost and shorter timeline than full custom OEM, but the formula is not unique to you unless exclusivity is negotiated.

Contract Manufacturing

A generic term for producing goods under a client’s brand. In supplements it usually means the factory handles purchasing, blending, filling, packaging, and QC, while the client handles branding and sales.

MOQ (Minimum Order Quantity)

The smallest batch a factory will run for commercial production. MOQ is driven by ingredient minimums, machine setup time, and label print runs. Honson’s MOQ starts from 300 bottles per SKU.

Encapsulation

The process of filling powder or pellets into capsule shells using an encapsulating machine. Output is measured in capsules per hour; blend uniformity and fill-weight consistency are the two quality variables to monitor.

Compression

The tableting step where powder is pressed between punches. Common defects include capping (top layer separates), lamination, and sticking, all of which are controlled by granule preparation and punch condition.

Film Coating

A thin polymer layer sprayed onto tablets to mask taste, protect the active from light or moisture, or ease swallowing. Enteric coating is a special case that resists stomach acid and releases in the intestine.

Blend Uniformity

A measure of how evenly an active is distributed through a powder batch. Poor uniformity means some capsules or gummies carry too little active and some too much. Verified by sampling at several points in the blender.

Lead Time

The interval from order confirmation to goods leaving the factory. It typically covers raw material procurement, production, QC release, and packaging. Standard production for supplements is commonly three to four weeks after sample approval.

Quality and Testing

COA (Certificate of Analysis)

A document listing the result of each test run on a specific batch – assay, heavy metals, microbial counts, and physical properties – signed by the laboratory. A COA is batch-specific; a generic spec sheet does not replace it. See quality control.

cGMP (Current Good Manufacturing Practice)

The manufacturing standard enforced by the FDA for dietary supplements. It covers facility design, equipment qualification, batch records, cleaning validation, personnel training, and complaint handling. Compliance is verified through inspection and internal audit.

21 CFR Part 111

The specific section of the US Code of Federal Regulations that defines cGMP requirements for dietary supplements. When a US buyer asks whether a factory is “GMP compliant”, Part 111 is the standard being referenced.

HACCP

Hazard Analysis and Critical Control Points – a systematic food-safety framework that identifies where contamination could occur and sets limits at each control point. Common prerequisite for retail and club-channel supply.

ISO 22000

An international food-safety management standard covering the whole supply chain from raw material to finished product. It layers HACCP principles into a documented management system with defined responsibilities and audit cycles.

NSF Certification

Independent certification by NSF International that a facility and its processes meet the NSF/ANSI 455-2 GMP standard for dietary supplements. Requires scheduled third-party audits and product testing. See certifications.

BRCGS

A Global Standard for Food Safety, widely required by UK and European retailers. It assesses hygiene, process control, traceability, and management commitment through an audited scoring scheme.

HALAL Certification

Confirms that a product and its production line comply with Islamic dietary requirements. For capsules and softgels, the critical question is the origin of the gelatin shell – porcine gelatin is not permissible. See GCC and Saudi halal supplements.

Third-Party Testing

Laboratory analysis performed by an independent lab rather than the factory’s own. Buyers request it to verify identity, potency, and contaminant levels without relying on self-reported results.

Assay

The test that measures how much active ingredient is actually present versus the label claim. Results are usually expressed as a percentage of label claim, with an acceptable range defined in the specification.

Heavy Metals Testing

Screening for lead, arsenic, cadmium, and mercury. Limits differ by market and by ingredient – botanical extracts and marine-sourced ingredients carry higher baseline risk and need tighter specification limits.

Microbial Testing

Testing for total aerobic count, yeast and mold, E. coli, Salmonella, and Staphylococcus. Critical for gummies and liquids, which have higher water activity than dry powders.

Stability Testing

Accelerated and real-time studies that show how a product degrades over its shelf life under controlled temperature and humidity. The output justifies the expiry date printed on the label.

Shelf Life

The period during which a product stays within specification when stored as directed. Typically 18 to 24 months for supplements, and heavily influenced by moisture barrier packaging and the stability of the active.

Ingredients and Formulation

Active Ingredient

The component intended to deliver the product’s benefit, as opposed to the components that merely hold it together. Label and COA thresholds are set against the active.

Excipient

Inactive materials used to make a dose form work – fillers, binders, lubricants, disintegrants, flow agents, and coatings. Excipients rarely appear on the front label but are listed in the Supplement Facts or ingredients panel, and they can carry halal or allergen implications.

Standardized Extract

A botanical extract adjusted to a defined marker compound, for example ashwagandha standardized to withanolides. Standardization is what makes dosing repeatable between batches; unstandardized powders vary widely in potency.

Bioavailability

The proportion of an ingested dose that reaches circulation in a usable form. Formulators raise bioavailability through delivery technology – liposomes, micelles, or enhanced-absorption salt forms – rather than simply raising the dose.

Liposomal

An encapsulation technique where the active is wrapped in a phospholipid bilayer. Used to protect sensitive ingredients such as vitamin C, glutathione, and NAD precursors from degradation and to improve absorption.

Sustained Release

A formulation designed to release the active gradually rather than all at once. Achieved through matrix tablets, coated beads, or controlled-particle capsules. Useful for ingredients with short half-lives or gastric upset at high doses.

Overages

Extra active added during manufacturing to compensate for losses during production and degradation over shelf life, ensuring the label claim holds at expiry rather than only at release. Overages must be declared in the batch record and are limited by regulation in some markets.

Serving Size

The amount of product defined as one dose – for example two gummies or one scoop. All label claim values are expressed per serving, so a serving of four gummies delivers four times the listed amount.

Servings Per Container

Total servings in a package, calculated as net content divided by serving size. This number drives cost per serving, which is the metric retail buyers compare most often.

Compliance and Trade

Structure/Function Claim

A statement that describes how a nutrient or ingredient affects normal body function – “supports immune health”, “helps maintain healthy bones”. These are permitted for supplements in the US. Claims that a product treats, prevents, or cures a disease are drug claims and are not permitted.

DSHEA

The Dietary Supplement Health and Education Act of 1994, the US law that created the modern supplement category. It defines what a dietary supplement is, sets the framework for claims, and establishes the pre-market notification route for new ingredients.

Supplement Facts Panel

The standardized nutrition label required on US dietary supplements, listing serving size, amounts per serving, and percent daily values. Format rules are prescriptive and a frequent source of import delays when done incorrectly.

FDA Facility Registration

Registration of a manufacturing facility with the US FDA as a food facility. It is a registration requirement, not an approval or certification, and it must be renewed biennially.

NDI (New Dietary Ingredient)

An ingredient not marketed in the US before October 1994. Using one requires a pre-market notification to the FDA at least 75 days before sale, supported by safety data. Missing this step is one of the most common compliance failures for new formulas.

Label Compliance Review

Checking a finished label against the target market’s rules – claim wording, ingredient naming, allergen disclosure, net quantity format, and required warnings – before printing. Cheaper to fix in artwork than after a customs hold.

3PL (Third-Party Logistics)

An outside warehouse that stores finished goods and picks, packs, and ships orders on your behalf. Key selection criteria are inbound receiving accuracy, storage conditions, and integration with your sales channels.

Fulfillment

The end-to-end handling of finished goods after production – warehousing, order processing, packing, labeling, and carrier handover. Split fulfillment between China and the US lets brands serve domestic buyers quickly while manufacturing offshore.

DDP (Delivered Duty Paid)

A shipping term where the seller arranges and pays for transport, import clearance, duties, and taxes, delivering to the buyer’s door. The buyer’s cost is fixed and predictable, which is why DDP is common for first orders into new markets.

MOQ Ladder

A price schedule where the unit cost decreases as order volume rises. Understanding the ladder matters because the cheapest per-unit price is often at a volume the brand cannot yet sell through.

Frequently Asked Questions

What is the difference between private label and OEM?

Private label uses a formula the factory already developed and offers to many brands. OEM builds to your own specification, so you own the formula. Private label is faster and cheaper; OEM gives differentiation and control.

Do I need a COA for every batch?

Yes. A COA is batch-specific evidence of what was tested and what the results were. Retailers, marketplaces, and importers increasingly ask for the COA matching the exact lot number on the carton.

What does cGMP mean in practice?

It means documented, repeatable production – qualified equipment, written batch records, validated cleaning, trained staff, and a complaint system. In the US the governing standard is 21 CFR Part 111.

How long does supplement production take?

Standard production runs three to four weeks after sample approval, depending on format and order size. Gummies and effervescents usually need additional stability work before the first commercial run.

What is a typical minimum order quantity?

MOQ depends on format and packaging. Honson’s MOQ starts from 300 bottles per SKU, which is set up to let new brands test a market without committing to container-scale volume.

Is a halal certificate required for capsules?

For GCC and Southeast Asian markets, usually yes – and the deciding factor is the capsule or softgel shell. Bovine gelatin must come from halal-slaughtered, auditable supply, while HPMC and fish gelatin avoid the issue entirely.
