No. A testimonial is held to the same standard as your own copy, and a cure claim is prohibited outright in all four markets, each under a different instrument. What changes the answer is the claim — not who says it.
“I cured my insomnia with this.”
The same sentence, four answers. Each row names the provision that decides it, so you can go and read the one that applies to you.
A claim to cure a disease takes the product out of the definition of a dietary supplement and into the definition of a drug under §201(g). No substantiation, disclaimer or attribution reaches that: an unapproved drug claim is not a labelling problem, it is a different regulatory category.
Article 7(3) of the food information regulation forbids attributing to a food the property of preventing, treating or curing a human disease. Article 14 of Reg 1924/2006 confines disease-risk-reduction claims to an authorised list, which a testimonial cannot join.
Schedule 20 of the DMCCA 2024 lists practices that are unfair in all circumstances, and falsely claiming that a product cures illness is one of them. Unfair in all circumstances means no defence is available on the facts.
The same food-information bar applies, reinforced by HWG §3 on misleading health advertising and by UWG §5. Germany also lets a competitor enforce it directly by Abmahnung, without waiting for a regulator.
Not softer wordings — authorised ones. Each is permitted for a stated reason, which is what makes it survive a review rather than merely go unnoticed.
The wordings below are checked in English. If you advertise in French, Spanish, Italian or Dutch, our rule vocabulary for those languages is still being built — the verdicts here hold for the English text shown, and your own translated copy needs its own check.
“Melatonin contributes to the reduction of time taken to fall asleep.”
An authorised Union Register entry for melatonin, subject to its stated conditions of use. Sleep is one of the few areas where a permitted route genuinely exists, and Article 10(1) requires the claim to appear substantially as authorised.
“Melatonin helps to alleviate subjective feelings of jet lag.”
A second, separate register entry for the same nutrient with a different condition of use. The register is per claim rather than per ingredient, so being allowed one wording says nothing about another.
“A source of melatonin. Melatonin contributes to the reduction of time taken to fall asleep.”
The nutrient-content claim that licenses the health claim, stated beside it. Article 10(3) permits a general reference to a benefit only alongside a specific authorised claim.
These three are ours. Your product, your nutrient levels and your markets are not — paste your actual copy and see what it says.
