Composition analysis
Food supplement: the checks below follow French and EU rules and are in French.
Food supplement : 9 vitamins or minerals, 0 plantes, 8 other ingredients. The daily dose is not stated: the quantities read cannot establish whether a daily dose is met or exceeded. See the references below.
For a complete answer, add the daily dose stated on the packaging to the end of the text (for example, ‘1 capsule per day’) and the quantity table (‘per 2 capsules: vitamin C 80 mg…’), or paste the product page link in the ‘link’ field below: we read the list, table and dose from it.
A food supplement is read differently from a cosmetic: daily doses and plants are what matter. References: maximum dose per supplement in France (Order of 9 May 2006, not revised since November 2006), EFSAEuropean Food Safety Authority. safety limit for adults, list of authorised plants (Order of 24 June 2014).
