Jusqu'où c'est sûr

Pour un adulte, l'EFSAEuropean Food Safety Authority. fixe la limite supérieure de sécurité à 600 µg/j : c'est l'apport quotidien qui, pris sur le long terme, toutes sources alimentaires réunies, ne devrait pas provoquer d'effet indésirable. Au-delà, le risque augmente. Un complément n'est qu'une partie de l'apport.

La règle en France

En France, la dose journalière recommandée d'un complément ne doit pas apporter plus de 150 µg (arrêté du 9 mai 2006, non révisé depuis novembre 2006). Compl'Alim ne publie pas la dose des produits déclarés : comparez celle de l'étiquette à ce plafond et à la limite de sécurité de l'EFSA.
