- À vérifier
Manganèse: up to 48 mg a day according to the label, above the niveau de sécurité from EFSAEuropean Food Safety Authority. for adults (8 mg a day). Son dépassement ne permet pas, à lui seul, de caractériser un risque : l'EFSA n'a pas pu fixer de limite supérieure pour ce nutriment. Le repère de l'EFSA porte sur l'apport total d'une journée, alimentation et compléments.

A daily dose is calculated only if the label gives the maximum number of servings and a unit of mass (or international units for vitamin D). Quantities come from the label, not an analysis. In the United States, the label presents this product as a ‘dietary supplement’; in France, a product of this type may belong to another category (a sports powder, for example), and maximum food supplement doses do not apply to it.
