GVH said it established that Ledland, which operates a multi-level marketing system, made unproven health claims in advertisements between 2008 and 2015 of its colloid and PentaMax C-vitamin bomb products, unlawfully attributing therapeutic effects to the products and claiming that they had been tested and certified as excellent by the European Independent Quality Control Team.

GVH prohibited the company from continuing the practice and ordered it to publish a rectification.

GVH also noted that, according to Hungaryʼs National Institute of Pharmacy and Nutrition, colloid solutions do not classify as nutritional supplements and their consumption carries a health hazard. Hungaryʼs National Food Chain Safety Office also says colloid solutions cannot be lawfully distributed in Hungary as food or dietary supplements, as they could have a harmful effect on health.
