If this product were sold in France
No point flagged by the rules we apply.
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.
