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
