Health claims on certain ingredients are only allowed if they have been approved by EFSA (European Food Safety Authority). This applies in particular to the group of vitamins, minerals and trace elements. There are fixed formulations for their health-specific effects (health claims) that must be used by all manufacturers and distributors in the EU. Therefore, do not be surprised to find identical formulations on packaging, in brochures and on the websites of different manufacturers. Despite the identical formulations, not all products are identical. The big difference is in the details, e.g. whether fillers are used, whether natural ingredients are used, whether the products are vegan or not genetically modified. No health claims may be made for ingredients that have not been approved by the EFSA, for example, due to a lack of long-term scientific studies. This is why you will only find specific health claims for very few herbal active ingredients, for example.
