Food supplements are among the most frequently challenged products in German unfair competition law. Competitors and associations enforce the strict EU rules through § 3a UWG.
Legal framework
- Health Claims Regulation (EC) 1924/2006: only authorised and listed health claims; general wellbeing claims need an accompanying authorised specific claim (Art. 10(3))
- Food Information Regulation (EU) 1169/2011: no misleading information; no claims about preventing, treating or curing diseases (Art. 7)
- NemV: mandatory particulars such as recommended daily dose and warnings
Case law
- BGH, 19 Sept 2019, I ZR 91/18 – general health claims need an accompanying specific authorised claim
- BGH, 25 June 2020, I ZR 162/16 – the specific claim must be visually linked to the general claim
- CJEU, 30 April 2025, C-386/23 – health claims for botanicals “on hold” are currently not permitted
- BGH, 6 Dec 2017, I ZR 167/16 – “Detox” is an unauthorised specific health claim
Case examples
A supplement says “for your immune system” on the front; the authorised vitamin C claim appears only on the back without a reference. That is not “accompanying” – the general claim is unlawful.
An ashwagandha product promises “less stress, better sleep”. As botanical claims are still on hold, such health claims are currently not allowed.
