Global Compliance Checklist for Immune Supplements: Labelling, Claims & Country-Specific Rules

The supplement industry has a compliance problem that nobody talks about at trade shows. Most contract manufacturers won‘t tell you why your product got flagged at customs—they’ll just apologize for the delay and suggest you “check with your regulatory team.” A US-focused facility will produce a flawless FDA-compliant label and accidentally violate EFSA rules on the same SKU. A manufacturer who understands EU Novel Food requirements will miss Australia‘s TGA listing distinction entirely. A brand that launches successfully on Amazon US discovers that its “immune support” claims trigger automated flags on Amazon EU—not because the claims are illegal, but because they haven’t been authorized under a different regulatory framework.

After 28 years of dietary supplement contract manufacturing, we‘ve watched this opacity kill more product launches than bad formulations ever could. We’ve seen brands ship an immune supplement to Germany with a label that was perfectly legal in the US, only to have the entire shipment detained because the claim language didn‘t match an EFSA-authorized phrase. We’ve seen brands enter Australia with a formula that met TGA requirements but failed at the border because the ingredient wasn‘t on the Permissible Ingredients Determination. We’ve seen brands assume that because vitamin C and zinc are “basic” ingredients, they must be compliant everywhere—only to discover that dosage conditions for authorized claims differ by market, and their product underdosed the nutrient relative to the claim on the label.

These aren‘t edge cases. They’re the predictable results of treating compliance as a label exercise rather than a formulation constraint.

This checklist is written from the factory floor, not a law firm. It covers the four regulatory questions that determine whether your immune supplement can legally be sold in a given market: what claims are allowed, what the label must contain, how the ingredient is classified, and what documentation the manufacturer must provide. It does not replace legal counsel—but it tells you what to ask your regulatory team and what to specify to your manufacturer before production begins.

The Four Regulatory Gates Every Immune Supplement Must Pass

Compliance is not a single check. It‘s a sequence. A product that passes Gate 1 may fail Gate 3. A manufacturer who understands Gate 4 may have no expertise in Gate 2. The sequence matters because the gates have different owners: formulation determines Gate 1, regulatory strategy determines Gate 2, ingredient sourcing determines Gate 3, and manufacturing documentation determines Gate 4.

Gate 1: Claims—What You Can Legally Say About Immune Support

The claims landscape for immune supplements is the single most misunderstood compliance area. Brand owners often assume that because “supports immune health” feels general and harmless, it must be permitted everywhere. That assumption is wrong.

In the United States, structure/function claims like “supports immune health” or “helps maintain a healthy immune system” are permitted for dietary supplements under DSHEA, provided the label carries the mandatory disclaimer: “This statement has not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.” The FDA does not pre-approve these claims—you are responsible for substantiation and for ensuring the claim does not cross into disease territory.

The EU operates under a fundamentally different system. Under Regulation (EC) No 1924/2006, no health claim may appear on a food supplement unless it has been scientifically assessed by EFSA and authorized by the European Commission into the EU Register of authorized claims. The authorized phrases are narrow and specific. “Vitamin C contributes to the normal function of the immune system” is authorized, subject to meeting the dosage condition for that claim. “Supports immune health” is not an authorized phrase and cannot appear on an EU label or in EU marketing.

The practical implication for immune supplements is significant. Vitamin C, zinc, and vitamin D have authorized immune-related claims in the EU, but only when the product delivers the required dosage per daily serving. A product that carries the claim “zinc contributes to the normal function of the immune system” but underdoses the zinc is the most common quiet violation in the EU market. EFSA assesses the nutrient-effect relationship, not your specific product; whether your bottle actually contains the effective dose is a quality-control question separate from the claims system.

Botanical ingredients present an additional layer of complexity in the EU. Health claims for botanicals have been “on hold” since 2010—EFSA suspended assessment amid a clash between the clinical-trial standard and traditional-use frameworks. In April 2025, the Court of Justice of the European Union ruled that health claims for botanicals are banned unless covered by transitional provisions for claims submitted by 2008. The practical effect is that echinacea, elderberry, and other immune botanicals cannot carry authorized health claims in the EU unless the specific claim was on the “on-hold” list and is legally usable in the specific member state under transitional provisions.

The claim strategy question is therefore not “what do I want to say?” It‘s “what can I legally say in each target market, and does my formulation support that claim at the required dosage?”

Gate 2: Label Content—Mandatory Elements by Market

Label compliance failures are the most common and most avoidable source of delay in getting an immune supplement to market. They happen at the artwork stage, after formulation and dossier work is complete, and they reset timelines at the worst possible moment.

The table below summarizes the mandatory label elements for immune supplements in the major markets Runxin produces for. This is a checklist for artwork development, not a substitute for regulatory review.

The cross-market labelling trap is real. A label designed for the US will be missing the EU nutrition declaration. A label designed for the EU may use authorized claim wording that differs from the GB Register. A label designed for Australia may lack the NPN required for Canada. The practical approach is to design a base label architecture that accommodates the most complex market‘s requirements, then create separate artwork versions for each market. Adaptation is cheaper than rejection.

Gate 3: Ingredient Classification—The Borderline Problem

Immune supplement ingredients fall into three regulatory categories, and the category determines what’s possible. The same ingredient can be in different categories in different markets.

Permitted supplement ingredient is the simplest case. Vitamin C, zinc, vitamin D, and echinacea are generally recognized as supplement ingredients in the US and many other markets. In the EU, vitamin C and zinc are permitted, but echinacea’s status depends on the specific extract and its history of consumption in Europe before 1997.

Novel Food is the EU-specific category for ingredients not consumed to a significant degree before May 1997. An ingredient that is a perfectly legal supplement in the US may trigger Novel Food assessment in the EU. This is not a claim issue—it‘s an ingredient legality issue. If the ingredient requires Novel Food authorization and doesn’t have it, the product cannot legally be sold in the EU regardless of what the label says.

Medicinal product classification is the most restrictive. The UK MHRA defines a medicinal product as any substance presented as having properties for treating or preventing disease, or that may be used to restore, correct, or modify physiological functions by pharmacological, immunological, or metabolic action. Immune claims that cross into “treating colds” or “preventing infections” risk pulling the product into the medicinal category, which requires a marketing authorization that dietary supplements do not have.

The ingredient classification question must be answered before formulation begins. A formula that uses an ingredient requiring Novel Food authorization, without that authorization, cannot be rescued by changing the label or the claims.

Gate 4: Manufacturing Documentation—What the Factory Must Provide

The manufacturer‘s compliance obligations do not end at producing a batch that meets specification. The manufacturer must provide documentation that supports the product’s regulatory position in each target market. The documentation requirements vary by market and by sales channel.

For Amazon compliance in the US and EU, third-party testing and ISO 17025-accredited Certificates of Analysis are increasingly required. A manufacturer‘s internal COA may not be sufficient for Amazon’s TIC (Testing, Inspection, Certification) requirements. The COA must include assay potency, microbial limits, heavy metals, and identity verification—and the laboratory that issued it must be accredited.

For EU market entry, the technical dossier supporting the product notification includes ingredient specifications, COAs, GMP certificates, scientific substantiation for any claims, and stability data. The manufacturer must be able to provide these documents in a format acceptable to the national competent authority.

For Middle Eastern markets, HALAL certification is required for the product and, in some cases, for the manufacturing facility. The certification covers the entire supply chain, including capsule shell material (gelatin source must be HALAL-certified) and any processing aids.

The documentation question to ask your manufacturer is not “do you have a COA?” It’s “can you provide the specific documentation package required by my target market‘s regulatory authority and my sales channel’s compliance team?”

The Compliance Sequence: What to Do Before Production

The brands that succeed in immune supplements across markets are the ones that sequence compliance before formulation, not after. The sequence is:

Step 1: Market selection. Which countries will you sell in? Each country has a different claims framework, label format, and ingredient classification system. The most restrictive market should drive your formulation and claim strategy, not the easiest.

Step 2: Claim strategy. For each target market, identify which immune claims are legally available for your ingredients. In the US, structure/function claims with DSHEA disclaimer. In the EU, authorized EFSA phrases with dosage conditions. In Australia, claims permitted under the Therapeutic Goods Advertising Code.

Step 3: Ingredient verification. For each active ingredient, confirm its regulatory status in each target market. Is it a permitted supplement ingredient? Does it require Novel Food authorization? Does it risk medicinal classification?

Step 4: Label architecture. Build the label to accommodate the most complex market‘s requirements first. Add market-specific artwork versions rather than trying to make one label work everywhere.

Step 5: Documentation specification. Tell your manufacturer which documentation package you need for each market: COA format, testing panel, certification requirements.

Step 6: Production. Only after Steps 1-5 are resolved should the first batch be produced.

Frequently Asked Questions

Can I use the same label for the US and EU?

No. The US requires a Supplement Facts panel and DSHEA disclaimer for structure/function claims. The EU requires a nutrition declaration, allergen declaration in a specific format, and health claims that match authorized EFSA wording. A label that complies with one will not comply with the other without modification. Build a base architecture, then create separate artwork versions.

Is “supports immune health” a legal claim?

In the US, yes, with the DSHEA disclaimer. In the EU, no—it is not an authorized EFSA claim. The authorized EU claim for vitamin C is “contributes to the normal function of the immune system,” subject to dosage conditions. For botanicals in the EU, health claims are restricted following the April 2025 CJEU ruling.

What is the biggest compliance mistake immune supplement brands make?

Assuming that because an ingredient is “natural” or “basic,” it must be compliant everywhere. Vitamin C is compliant in the US and EU, but the authorized claim in the EU has a dosage condition. Echinacea is a supplement ingredient in the US but may require Novel Food assessment in the EU. Zinc is permitted in both, but the claim wording differs.

Do I need Novel Food authorization for my immune supplement ingredients?

It depends on the ingredient and the target market. Novel Food is an EU-specific requirement for ingredients not consumed to a significant degree before May 1997. If your ingredient requires Novel Food authorization and doesn‘t have it, the product cannot legally be sold in the EU. Verify ingredient status before formulation.

What testing does Amazon require for immune supplements?

Amazon’s TIC (Testing, Inspection, Certification) program requires third-party testing and ISO 17025-accredited Certificates of Analysis. A manufacturer’s internal COA may not be sufficient. The COA must include assay potency, microbial limits, heavy metals, and identity verification from an accredited laboratory.
