Label Claims for Dietary Supplements: FDA, EFSA, Health Canada Compliance Guide

Of every line on a supplement label, the claims are the most dangerous to get wrong. A single word — "treats," "cures," "prevents" — can turn a compliant product into an unapproved drug claim and trigger a warning letter, a recall, or a market-entry block. For brands selling across borders, the risk doubles: what is permitted in the United States is frequently prohibited in the European Union, and Canada runs its own pre-approval system entirely.

Why Claims Are the Highest-Risk Element

Two forces make claims a compliance flashpoint:

1. Regulatory divergence. Each market defines "allowed claim" differently, and none accepts another's approval.
2. Dual enforcement. In the U.S., the FDA polices health and disease language while the FTC polices advertising substantiation. A claim can be simultaneously "FDA-clean" and "FTC-weak" if the evidence is thin.

The cheapest compliance error to avoid is also the most common: assuming a claim that worked in one market transfers to another. It usually does not.

The Claim Categories Brands Confuse

Before comparing jurisdictions, fix the vocabulary:

• Structure/function claims — describe how an ingredient affects the structure or function of the body (e.g., "supports immune health"). Permitted in the U.S. under conditions.
• Disease claims — imply diagnosis, treatment, cure, mitigation, or prevention of a disease. Prohibited for supplements in every major market.
• Authorized health/nutrition claims — pre-approved, evidence-backed claims tied to a specific food-ingredient relationship (EU and Canada models).

The line between "supports heart health" and "lowers blood pressure" is where most brands fall. The second is a disease claim almost everywhere.

United States: The FDA Framework

The U.S. system, built on the 🔗[[Dietary Supplement Health and Education Act of 1994 (DSHEA)]], lets supplements make structure/function claims without pre-approval — but with strict guardrails.

Structure/Function Claims and the Mandatory Disclaimer

Any label bearing a structure/function claim must carry the statutory disclaimer required under 🔗[[21 CFR 101.93]], worded exactly:

"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."

Misspelling or paraphrasing the disclaimer is a common FDA citation. The wording is fixed.

The 30-Day Notification

Under DSHEA, a company must submit a 🔗[[structure/function claim notification]] to FDA no later than 30 days after first marketing a product bearing such a claim. The notification is not an approval — FDA does not sign off — but failing to file it is a violation. Brands should keep the submission confirmation on file for every SKU.

Disease Claims Are Prohibited

A supplement may not claim to diagnose, treat, cure, mitigate, or prevent any disease. Crossing this line reclassifies the product as an unapproved drug. The prohibition is absolute and is the single largest source of FDA warning letters.

FTC Substantiation

The FTC requires "competent and reliable scientific evidence" for claims made in advertising. Even where FDA permits the wording, the FTC can act if the backing is inadequate. Build a substantiation file before launch.

cGMP Backs the Claim

Claims rest on a quality system. 🔗[[Supplement cGMP (21 CFR Part 111)]] requires identity, purity, strength, and composition controls — without them, even a permitted claim is unsupported. Our 🔗[[supplement quality certifications guide]] covers the underlying quality framework.

European Union: The EFSA Framework

The EU takes the opposite philosophy: health claims are pre-authorized, not notified.

Regulation (EC) No 1924/2006

All nutrition and health claims on foods and supplements are governed by 🔗[[Regulation (EC) No 1924/2006]]. A claim may only be used if it is listed as authorized in the EU Register and is accompanied by the specified wording and conditions of use.

EFSA Scientific Assessment

Every health claim passes through an 🔗[[EFSA scientific assessment]] of the cause-and-effect relationship between the ingredient and the claimed effect. Only claims with favorable EFSA opinions and subsequent Commission authorization enter the Register. There is no self-declared structure/function equivalent as in the U.S. — if it is not on the list, you cannot use it.

Disease Claims and the Medicinal Border

As in the U.S., disease prevention and treatment claims are barred for food-supplement products and would push the product into medicinal-product territory, requiring a marketing authorization. The line is policed strictly.

Novel Food Is Separate

Ingredient authorization is distinct from claims. Botanicals and actives not widely consumed in the EU before 15 May 1997 fall under 🔗[[Novel Food Regulation (EU) 2015/2283]] and need their own authorization before any claim can appear. Our 🔗[[plant extract supplier guide]] discusses traceability and documentation that supports both novel-food and claim dossiers.

Canada: The Health Canada NHP Framework

Canada pre-approves both products and claims through the Natural Health Products Regulations (NHPR).

Product and Site Licensing

Every natural health product (NHP) needs a product licence and an eight-digit 🔗[[Natural Product Number (NPN)]], issued by Health Canada after review. The site that manufactures, packages, or labels it also requires a site licence. No NPN, no legal sale.

Claims Come From the Monograph or Application

Permitted claims are tied to the product's approved licence and supported by a published monograph or a successful product licence application. Brands cannot invent structure/function wording freely — the claim set is fixed at authorization.

Bilingual Labeling

All NHP labels must be in both English and French, including claims, warnings, and the NPN statement. This is a labeling requirement absent in the U.S. and EU.

Cross-Market Comparison

Documentation Buyers and Brands Must Keep

A claim is only as defensible as its paper trail. Maintain:

• Claim substantiation file — studies, summaries, and the rationale behind each claim.
• Structure/function notification proof (U.S.) — the 30-day filing confirmation.
• EU Register reference — the exact authorized wording and conditions for each EU claim.
• NPN and licence copy (Canada) — plus the approved claim set.
• Ingredient authorization proof — novel-food status, GMP, and 🔗[[COA, MSDS, and third-party testing]] that support the product's identity and purity.

Practical Steps for a Compliant Launch

1. Map claims to each target market before writing copy — never translate a U.S. label for the EU or Canada.
2. Keep a substantiation file for every claim, regardless of market.
3. Use approved wording verbatim — paraphrase is risk.
4. Stay clear of disease language in all markets.
5. Confirm ingredient authorization (novel food, NDI, NPN) before claiming benefits.
6. Verify the quality system — claims are only as strong as the 🔗[[cGMP and certification]] behind the product.

FAQ

Do U.S. supplements need pre-approval for claims?

No. Under DSHEA, structure/function claims are allowed without pre-approval, but you must file a notification within 30 days of first marketing and print the mandatory FDA disclaimer.

Can I use the same label in the U.S. and EU?

No. The EU requires pre-authorized claims from the EU Register with specific wording; the U.S. allows notified structure/function claims with a disclaimer. The two are not interchangeable.

What is the exact FDA 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 wording is fixed by 21 CFR 101.93.

What is an NPN?

A Natural Product Number — the eight-digit licence identifier Health Canada issues for an authorized natural health product. It must appear on the Canadian label.

Who enforces claims in the U.S.?

The FDA polices label claims and disease language; the FTC polices the substantiation of advertising claims. Both can act.

Conclusion

Claims are where supplement compliance is won or lost. The U.S. notifies, the EU authorizes, and Canada licences — but all three forbid disease claims and all demand real evidence. Plan claims per market, keep your substantiation, and verify your ingredient and quality systems before you print.

At JHD GLOBAL, we supply ingredients with the documentation — CoA, MSDS, third-party testing, and traceability — that underpins a defensible claim file across all three regions.
