The Advertising Standards Authority has upheld a complaint about a display-box advertisement of No-Jet-Lag in an Auckland pharmacy.
The Society for Science Based Healthcare had complained the ad's claims that the product really worked as a homeopathic form of jet-lag prevention were unsubstantiated and misleading.
No-Jet-Lag's manufacturer submitted a study as proof to the authority, but it found that the methodology was not robust, and the results had not been published or peer-reviewed.
It said given the weakness of the study, the advertiser had not satisfactorily proved the product really worked, so the ad had the potential to mislead consumers.
