How to Choose a Contract Manufacturer for Vitamin Gummies

Why gummies are harder than capsules or tablets

A capsule is essentially a container for powder. A gummy is a food matrix that must carry active ingredients while staying chewable, tasty and stable on a shelf in hot, humid markets. That creates several technical challenges your manufacturer must handle:

• **Active stability**: some vitamins degrade with heat during cooking and depositing, or over time with moisture and light. Manufacturers typically build an overage into the formula to compensate, which requires stability data to justify.
• **Taste masking**: minerals like iron or zinc and some botanicals taste metallic or bitter. Masking them without excessive sugar is a skill.
• **Texture and sweating**: gummies can harden, stick together or sweat in humid storage. Coating, curing time and packaging all matter.
• **Dose per piece**: there is a practical limit to how much active ingredient fits into one gummy before taste and texture suffer. High-dose claims may require two or more gummies per serving.

Because of these factors, a manufacturer that is excellent at tablets is not automatically good at gummies. When you evaluate a **health supplement OEM** partner, ask specifically about gummy experience: how long they have run gummy lines, which bases they work with and which actives they have successfully stabilised. General supplement experience is helpful, but gummy-specific know-how is what protects your launch.

Decisions to make before you contact manufacturers

Manufacturers can only quote accurately when you arrive with a clear brief. Decide, or at least shortlist, the following:

• **Base**: gelatin or pectin. Pectin suits vegetarian and many halal positioning needs and tends to handle heat better; gelatin gives a classic chewy texture. Your target market and claims should drive this choice.
• **Sugar profile**: regular, reduced sugar or sugar-free with polyols. Sugar-free gummies can be more challenging for texture and may carry laxative-effect labelling in some markets.
• **Actives and dose**: list each vitamin, mineral or botanical with your target amount per serving.
• **Flavour, colour and shape**: natural colours and flavours are popular but may behave differently from synthetic ones.
• **Packaging**: bottle with desiccant, stand-up pouch, or blister. Packaging affects shelf life significantly.
• **Target markets**: regulations for supplements differ widely, including permitted ingredients and maximum levels.

Write these into a one- or two-page product brief. This is the foundation of **formula development**, and it lets you compare manufacturers on the same basis. If you are unsure on some points, say so in the brief; a good manufacturer will recommend options and explain the trade-offs rather than simply saying yes to everything.

Evaluating technical capability

Once you have a shortlist, assess each manufacturer's technical depth. Useful questions include:

• **Production setup**: do they deposit gummies in-house on dedicated equipment, or subcontract part of the process? Starch-mould and starchless depositing systems each have implications for shapes and hygiene.
• **Formulation team**: who develops the formula, and how many revision rounds are typical? Ask to see how they document changes between samples.
• **Stability testing**: what stability protocol do they run, under which temperature and humidity conditions, and how do they set shelf life and overage?
• **Analytical testing**: can they test active content in finished gummies, either in-house or through an external lab? Ask which methods they use for key actives.
• **Quality systems**: request copies of relevant certifications such as GMP and check the scope covers food supplements and the site that will produce your product.
• **Allergen and cross-contact controls**: important if you plan claims like gelatin-free or allergen-free.

An **OEM manufacturer in Thailand** that is genuinely capable will answer these questions with documents, not just reassurance. Ask for anonymised examples of stability reports or certificates of analysis from previous projects so you can see the level of detail they provide.

Regulatory fit for your target markets

Gummies are usually regulated as food supplements, and each market has its own rules. In Thailand, food supplements require registration with the Thai FDA before sale, and the product must be produced at a licensed facility. If you plan to export, the destination country's authority sets its own requirements on permitted ingredients, maximum daily amounts, health claims and labelling.

When evaluating manufacturers, ask:

• Which markets have they supported with documentation before?
• Can they provide ingredient specifications, certificates of analysis and manufacturing documentation for registration files?
• Do they understand claim restrictions, for example the difference between a nutrient function claim and a disease claim?
• Can they adapt the formula for different markets if one ingredient is restricted somewhere?

Treat any information from a manufacturer as support, not as a final regulatory opinion. Always verify requirements with the relevant authority or a regulatory consultant in each market. Building regulatory needs into the brief early is far cheaper than reformulating after a registration is rejected. If you sell across several markets, consider designing one core formula that fits the strictest market you plan to enter, then adjust packaging and labels per country.

Commercial terms: MOQ, costs and timelines

Once technical and regulatory fit look good, compare commercial terms carefully.

• **Minimum order quantity**: many contract manufacturers work with a standard of around 1,000 units per SKU for OEM runs. Check how they define a unit (bottle or pouch) and whether different flavours count as separate SKUs.
• **Development costs**: ask what is included in sampling and formulation, and how many revisions are covered before extra charges apply.
• **Unit price structure**: request a breakdown covering formula, packaging, labelling and testing so you can see where costs come from. Prices depend on actives, dose and packaging, so expect quotes to vary.
• **Timelines**: ask for a timeline for each stage: sample development, stability testing, registration support, packaging procurement and production. Treat any timeline as an estimate to be confirmed in the quotation.
• **Ownership of the formula**: clarify whether you own the custom formula or license a stock one, and what happens if you move production later.

Some brand owners prefer a single partner that coordinates formula, packaging and production. For example, 5FINE manages supplement production through GMP-certified partner factories as one point of contact. Others prefer to contract a factory directly. Either can work; the right choice depends on how much coordination you want to handle yourself.

Red flags and a practical selection process

Watch for these warning signs during evaluation:

• Promises that any dose, any flavour and any claim is possible without discussing trade-offs.
• No stability data or reluctance to explain how shelf life is set.
• Vague answers about which site will actually produce your gummies.
• Certificates that do not match the company name or production site.
• Pressure to sign quickly or pay large deposits before samples are approved.

A practical process looks like this:

• **Shortlist** three to five manufacturers with confirmed gummy experience.
• **Send the same brief** and compare responses for depth and quality of questions.
• **Order samples** from two or three, and test them yourself and with a small panel of target customers. Store some samples in warm, humid conditions for a few weeks to see how texture holds up.
• **Review documents**: certifications, sample stability data and test methods.
• **Negotiate terms** and put specifications, testing responsibilities and formula ownership in writing.

Taking this structured approach is especially valuable if you are about to **start your own brand**, because the first product often sets the reputation for everything that follows.
