Private label immune support supplements for winter
PharmaEurope manufactures private label immune support supplements in the EU: vitamin C, vitamin D3 and zinc formulas, on their own or with elderberry, in effervescent tubes, sachets, powder, capsules and tablets. The authorised EU wording for these nutrients is that vitamin C, vitamin D and zinc contribute to the normal function of the immune system. Capsules and tablets start from 100 units on a ready-made formula with your label and from 500 bottles for your own formula; effervescent tablets have a low minimum order in tubes of 20; powder and sachets have a standard run from 300 kg of finished blend. Production takes from 2 weeks on a ready-made formula and from 4 weeks on your own. The plant is ISO 22000, GMP and HACCP certified, with tablets, capsules and powders in the certificate scope, and FDA registered; every batch ships with a Certificate of Analysis and a 24-month standard shelf life.
In short: demand for immune supplements peaks in winter, in December in the northern hemisphere and in June in Australia. Order in November and a ready-made formula, produced from 2 weeks, can be ready for this winter’s restock; shipping and your retailer’s steps come on top. For next season, order before summer.

Shopper search terms, not product effects. Monthly searches, Google Ads Keyword Planner estimates for October 2024 to September 2026; each month is the average of the same calendar month across the two years. Zinc is left out: its monthly figures in this period contain spikes with no seasonal pattern.
What the winter season decides for you
The order date is set by the day stock has to be on the shelf, not by the peak itself.
- The ingredient sells all year. Vitamin C and vitamin D3 searches stay high in every month, so the ingredient sells beyond winter: plan the first run for the season and the repeat order for the rest of the year.
- Earlier terms move first. Elderberry searches peak in August, months before the December peak, so an elderberry product needs to be on the shelf before autumn.
- Formats that dissolve in water suit larger servings. Effervescent tablets and sachets carry a serving that is dissolved in a glass of water; sachets and powder carry several grams of blend that a capsule cannot.
- The southern winter is the mirror. In Australia the seasonal peak falls in June, so the order for that market is placed while the northern season is still running.
- The label is decided by the nutrients, not by the season. Vitamin C, vitamin D and zinc carry the authorised EU immune claim; elderberry is named as an ingredient. The wording is below.
Which format for an immune support range, and what is the MOQ for each?
Each format has its own minimum order and its own unit: tubes for effervescent tablets, kilograms of finished blend for powder and sachets, units and bottles for capsules and tablets.

| Effervescent tablets | Ready-made: vitamin C alone or with zinc, vitamin D3 or bioflavonoids; a multivitamin and mineral complex | Low minimum order, quoted by tube count | From 2 weeks; your own formula from 4 weeks | Tube of 20 tablets of 4 g, sugar-free sorbitol base, desiccant cap | Effervescent tablet manufacturing |
| Sachets | Your own vitamin C, zinc and D3 blend | Standard run from 300 kg of finished blend | From 4 weeks | 4 to 12 g per sachet | Sachet manufacturing |
| Powder | Your own vitamin C, zinc and D3 blend | Standard run from 300 kg of finished blend | From 4 weeks | 450 g zip-lock bag; 900 g or 1,800 g in a bag or a jar | Powder manufacturing |
| Capsules | Ready-made: elderberry with vitamin C and zinc; liposomal vitamin C; liposomal zinc; zinc with copper | From 100 units on a ready-made formula with your label; your own formula from 500 bottles | From 2 weeks; your own formula from 4 weeks | Bottles of 30, 60, 90 or 120 | Capsule manufacturing |
| Tablets | Ready-made: vitamin C 500 mg or 1,000 mg with bioflavonoids; zinc 25 mg | From 100 units on a ready-made formula with your label; your own formula from 500 bottles | From 2 weeks; your own formula from 4 weeks | Bottles of 30, 60, 90 or 120 | Tablet manufacturing |
Vitamin D3 on its own, in softgels, tablets, liposomal capsules and effervescent tubes, is covered on the private label vitamin D page. The way each minimum is set is explained on the minimum order quantity page.

Doses are set to the national maximum of the destination market: Germany’s recommended maximum levels, for example, are lower than those of other member states, so a formula is adjusted for the country of sale. A different dose or composition is made as your own formula: from 500 bottles in capsules and tablets, from 300 kg of finished blend in powder and sachets, from 4 weeks. The full catalogue is on the ready-made formulas page.
When do I need to order immune supplements for winter?
Order in November and a ready-made formula, produced from 2 weeks, can be ready for this winter’s restock; shipping and your retailer’s steps come on top. For next season, order before summer. Your own formula takes from 4 weeks in production.
| Season | Search peak | When to order | Production time |
|---|---|---|---|
| This winter, northern hemisphere | December; vitamin C and “immune support” in January | November 2026, ready-made formula | From 2 weeks |
| Southern winter, Australia | June | Before the southern winter, with sea or air freight on top | From 2 weeks ready-made; from 4 weeks your own formula |
| Next winter, northern hemisphere | December | Before summer 2027 | From 2 weeks ready-made; from 4 weeks your own formula |
Production time runs from the approved formula and artwork. Shipping to your warehouse and your own retailer or marketplace steps come on top: send your target shelf date with the enquiry, and the production slot is planned back from it.
What can an immune supplement label say in the EU?
The label may say that vitamin C, vitamin D or zinc contributes to the normal function of the immune system, when the product is at least a source of that nutrient (Regulation (EU) No 432/2012):
- “Vitamin C contributes to the normal function of the immune system.”
- “Vitamin D contributes to the normal function of the immune system.”
- “Zinc contributes to the normal function of the immune system.”
Vitamin A, vitamin B6, vitamin B12, folate, copper, iron and selenium carry the same authorised claim. Elderberry and other botanicals have no authorised health claim and are named as ingredients. The brand stays responsible for its label in each country of sale; PharmaEurope produces from the brand’s approved artwork.

Questions about private label immune support supplements
What is the minimum order for private label immune support supplements?
PharmaEurope starts ready-made immune capsules and tablets from 100 units with your label, and your own formula in capsules and tablets from 500 bottles. Effervescent vitamin C has a low minimum order, quoted by the number of tubes of 20; powder and sachets have a standard run from 300 kg of finished blend.
When should I order immune supplements for the winter season?
Before summer, so the stock is in place well ahead of the December peak. PharmaEurope production takes from 2 weeks on a ready-made formula and from 4 weeks on your own formula; shipping and your retailer’s steps come on top.
Is it too late to restock immune supplements for this winter?
No. Order a ready-made formula from PharmaEurope in November, produced from 2 weeks, and it can be ready for this winter’s restock; shipping and your retailer’s steps come on top. Vitamin C and “immune support” searches peak in January, after the December peak. Send your target shelf date with the enquiry.
Which ready-made immune formulas does PharmaEurope make?
PharmaEurope makes effervescent vitamin C 1,000 mg alone or with zinc, vitamin D3 or bioflavonoids, and an effervescent multivitamin and mineral complex; elderberry 750 mg with vitamin C 100 mg and zinc 25 mg in capsules; liposomal vitamin C and liposomal zinc; zinc with copper; and vitamin C and zinc tablets.
What can an immune supplement label say in the EU?
That vitamin C, vitamin D or zinc “contributes to the normal function of the immune system”, when the product is at least a source of that nutrient. Elderberry and other botanicals have no authorised claim and are named as ingredients. The brand stays responsible for its label; PharmaEurope produces from the approved artwork.
Which doses can I sell in Germany and other EU countries?
PharmaEurope sets the dose to the national maximum of the destination market. Germany’s recommended maximum levels, for example, are lower than those of other member states, so a 1,000 mg vitamin C or 25 mg zinc formula may be adjusted for the country of sale. Tell us the market with the enquiry.
Effervescent tablets or capsules: which format for a winter immune range?
An effervescent tablet is dissolved in a glass of water and comes in a tube of 20 with a low minimum order. A capsule fits a product taken daily in bottles of 30, 60, 90 or 120, from 100 units on a ready-made formula with your label. PharmaEurope makes both, so one brand can launch the pair.
How long does production of an immune supplement take?
PharmaEurope production takes from 2 weeks on a ready-made formula in effervescent tablets, capsules or tablets, and from 4 weeks on your own formula, including powder and sachets.
Can you make immune supplements for Australia and the southern winter?
Yes. PharmaEurope ships worldwide, EXW as standard, FCA or DAP on request. Searches in Australia peak in June, so order before the southern winter with freight time on top of production. Australia sets its own rules for supplements, so your importer confirms the label before print.
What documents and shelf life come with an immune supplement batch?
Every PharmaEurope batch ships with a specification and a Certificate of Analysis. Shelf life is 24 months as standard, confirmed on every specification. The plant is ISO 22000, GMP and HACCP certified, with tablets, capsules and powders in the certificate scope, and FDA registered; copies of the certificates with their numbers are sent on request.
