Zinc Supplement Manufacturer
Elemental-zinc conversion done right — the salt named, the metallic taste solved, the interaction decided.
INGREDIENT SPOTLIGHT
Zinc Supplement Manufacturing — Your Formula, Our Line
We manufacture Zinc products on our partner lines in Zhengzhou, China. Bring a finished formula, a target active level or a rough concept, and we convert it into a specification we can run in bulk — salt form and elemental content included.
- Picolinate, citrate, gluconate and oxide salts
- Tablet, capsule, gummy and powder formats
- Elemental content declared against your specification
Zinc picolinate, citrate, gluconate and oxide where the salt form decides both the absorption story and the taste of the finished product.
12 Dosage Forms
Gummies, capsules, softgels, tablets, powders, liquids and solid beverages — all run in-house.
6 Production Lines
Two GMP facilities covering 14,000 sqm, 200+ employees, no subcontracted fill.
100+ Export Markets
cGMP, HACCP, ISO 22000 and HALAL certified. Documentation built for your market.

Why the Zinc Salt You Choose Decides the Whole Product
Zinc is specified as elemental but bought as a salt. Three decisions decide whether the whole product holds together.
Salt vs Elemental
Zinc is specified as elemental but bought as a salt, and the conversion is where things go wrong — gluconate is ~14% elemental, citrate ~31%, oxide up to 80%. We convert explicitly at specification stage and label as elemental zinc, so the number on the label is the number in the product.
Palatability
Zinc has a pronounced metallic taste that intensifies with certain salts, a common reason gummies and lozenges fail taste panels. The salt form, coating and flavour system must be chosen together — and a lozenge is harder again because the active stays in the mouth.
Interaction
Zinc competes with iron and copper for absorption. A formula carrying all three needs a separation strategy or an explicit decision about which nutrient leads — asked at specification stage, not discovered at nutrition-panel reconciliation.
Formats We Run
Tablets and coated tablets
Hard capsules and vegetarian capsules
Gummies, including sugar-free routes
Lozenges for throat and immune positions
Powders and effervescents
Liquids and drops for paediatric use
What We Check Before Release
Assay is reported as elemental zinc rather than salt weight
Assay is reported as elemental zinc rather than salt weight, because the two differ by a factor of two to seven depending on the salt and the distinction is where most labelling errors originate.
Taste is checked against a retained reference for every batch
Taste is checked against a retained reference for every batch, since the metallic note is the main reason a zinc product succeeds or fails with consumers and it is perceived long before it is measured.
Content uniformity is demonstrated across the batch
Content uniformity is demonstrated across the batch, which matters most at the lower paediatric doses where the active is a small fraction of the unit.
Heavy metals are tested against the destination market’s limits
Heavy metals are tested against the destination market’s limits, because zinc is frequently paired with other minerals and the combined load has to be considered as well as the individual figures.
Sourcing and Specification Notes
Elemental-zinc conversion differs sharpl…
Elemental-zinc conversion differs sharply by salt — oxide carries up to 80 percent and gluconate around 14 percent — so the specification must name the salt and the elemental figure together.
Zinc competes with iron and copper for a…
Zinc competes with iron and copper for absorption; a formula carrying all three needs an explicit separation decision rather than an assumption. The metallic taste is a genuine formulation constraint, and the salt form together with the coating or flavour system determines whether the product is acceptable.
Lozenges present a different challenge from tablets because the active stays in contact with the mouth
Lozenges present a different challenge from tablets because the active stays in contact with the mouth, so they are scoped as their own project with their own taste work. Paediatric doses sit at low elemental figures, which makes content uniformity the dominant technical concern rather than dose size.
Immune positioning commonly pairs zinc with vitamin C and vitamin D; the blend is a formulation task and the claim set varies by market, so both should be scoped together.
One Thing Buyers Get Wrong
The most common mistake is quoting a zinc specification in s… The most common mistake is quoting a zinc specification in salt weight while the label declares elemental zinc, or the reverse. The two figures can differ by a factor of several, and the error is invisible until the assay comes back or the customer’s quality team reconciles the nutrition panel. A brief that says 15 mg of zinc gluconate and a label that says 15 mg of zinc are not the same product, and the difference is a recall if it reaches the shelf. We state both figures explicitly in the specification and confirm the conversion in writing before the batch is scheduled.
Who This Serves: Men’s Daily-Vitality Lines
In men’s health the active is rarely the problem and the experience usually is — pungent, high-dose botanicals and minerals that smell like the ingredient they contain. A men’s SKU that smells like its ingredients is a one-time purchase. We build zinc and mineral stacks with real loading and odour masking that makes a daily habit actually happen, and we flag vitality claims that drift into restricted territory before artwork.
Popular Formulas We Run
The zinc salt and the mineral pairing set the formula — here are the standard builds.
Immune Zinc
Zinc picolinate or citrate 15–25 mg with vitamin C for immune support.
Mineral Trio
Zinc with magnesium and vitamin D3 for a daily mineral stack.
Skin + Zinc
Zinc bisglycinate 20–30 mg for an acne-and-skin-positioned capsule.

Frequently Asked Questions
What is the minimum order quantity for zinc products?
MOQ is confirmed per format and specification at quotation stage. Salt form, dose, format and packaging all move the figure — send us your target and we will quote exactly.
Which zinc salt should I use?
It depends on your dose, your format and your positioning. Picolinate and citrate are well regarded for absorption, gluconate is widely used in lozenges, and oxide is the most economical by elemental weight. We will explain the trade-offs for your specific brief.
How do you handle the metallic taste?
By choosing the salt form together with the coating or flavour system and by tasting the finished product against a retained reference. This is checked before artwork, not after.
Do you make zinc lozenges?
Yes. Lozenges are scoped as their own project because the active is in contact with the mouth for an extended period, which changes both the taste work and the dissolution expectations.
Can zinc be combined with vitamin C and vitamin D?
Yes, and it is a common immune formula. The blend is designed at formulation stage so the actives coexist without interfering with each other’s stability or absorption.
How long does bulk production take?
We reply to enquiries within 24 hours and send a quotation within 48. Samples take 2-3 days, and standard bulk runs complete in 5–10 days with packaged goods leaving in 10–15 days.
DOSAGE FORMS
Which format should your Zinc product take?
The same Zinc blend can be delivered in several forms, and each one changes the fill weight, the taste profile and the tooling. We produce tablet, capsule and gummy in-house, so the choice is driven by your market rather than by what a third party can supply.
