Professional verification of dietary supplement labels

In the dietary supplement industry, labels play a much greater role than just providing information. They are also a tool for communicating with consumers, an element that builds brand credibility, and – crucially – a legal document that must meet specific requirements. Incorrect labeling can lead to serious consequences: from the need to correct labels, through administrative penalties, to product withdrawal from the market.

That is why professional label verification is not an additional feature-today – it is a safety standard and proof of the manufacturer’s responsibility.

Why is correct labeling so important?

Unlike medicines, dietary supplements do not undergo a registration process with an efficacy assessment. This makes reliable information for consumers all the more important, as it must comply with regulations and be supported by expert knowledge.

A correctly prepared label:

  • protects the product from objections by regulatory authorities,
  • prevents misinterpretation by consumers,
  • reduces the risk of legal disputes,
  • strengthens the credibility of the manufacturer and seller,
  • ensures that the declarations are consistent with the facts.

The label thus becomes an integral part of safety – just like purity and microbiology testing or the labeling of active ingredients.

What do the regulations say? Key requirements that a supplement label must meet

The labeling of dietary supplements is regulated in parallel by:

  • Regulation 1169/2011 (FIC) – general rules for consumer information;
  • Directive 2002/46/EC – specific requirements for supplements;
  • Regulation 1924/2006 – nutrition and health claims;
  • Guidelines of the Chief Sanitary Inspectorate and national legislation.

Key mandatory elements include:

  • correct category name (“dietary supplement”),
  • list of ingredients with form and source,
  • active substances given in appropriate units,
  • recommended serving size,
  • method of use and warnings,
  • information on maximum permissible levels,
  • appropriate health claims,
  • prohibited content: suggestions of therapeutic effects, promises of treatment, declarations inconsistent with EFSA.

In reality, many errors are not due to the bad faith of manufacturers, but to a lack of up-to-date knowledge about changing regulations. It is in this area that a professional audit provides the greatest value.

How does label verification work at J.S. Hamilton?

Labeling audits are conducted by a team of food law specialists and food technologists who analyze labels from both a legal and practical perspective.

We check among others:

  1. Compliance with current EU and Polish regulations

Each element of the declaration is compared with the applicable regulations.

  1. Compliance of declared values with laboratory test results

The label cannot declare values that are not confirmed by analyses.

  1. Correct use of nutrition and health claims

We verify acceptable wording in accordance with the EFSA register.

  1. Correctness of active ingredient labeling

Units, chemical forms, conversions, extract standardizations.

  1. Mandatory warnings and instructions for use

In accordance with dietary supplement requirements and good industry practice.

  1. Visual communication elements

We avoid suggesting medicinal properties, risky associations, and inconsistent graphics.

The result is a complete expert opinion that the manufacturer can use as part of their quality documentation, including in the event of an inspection.

The most common errors we detect:

  • health claims that are not allowed to be used,
  • incorrect calculations of active ingredients,
  • lack of mandatory warnings,
  • incorrect naming of chemical forms,
  • use of illegal marketing claims,
  • inadequate contact details and incomplete information about the manufacturer,
  • graphics suggesting therapeutic effects.

Most of these problems can be avoided by performing an audit before printing the label.

Professional label verification — what does the manufacturer gain?

✔ Minimization of legal risk

A correct label means less risk of penalties, inspections, and recalls.

✔ Solid marketing foundation

Health claims are legally compliant but still attractive to the customer.

✔ Consistency between declaration and composition

We verify the label based on the results of supplement composition tests.

✔ Time and cost savings

Correcting a label after printing can be several times more expensive than auditing it before the product is launched on the market.

✔ Protection of brand reputation

Transparency and credibility are becoming a distinguishing feature in a competitive market.

A supplement label is more than just a product’s calling card. It is a document that must be accurate, legally compliant, and reliable. Professional verification helps avoid errors, builds consumer trust, and ensures legal security for the manufacturer.
