GNC Mega Men, food supplement from the US market
X12 (GNC Mega Men), a food supplement without a usable barcode in DSLD, is described by its US market label, recorded on 25 September 2013. The French and European rules we can apply to this label flag no particular point. Doses of niacine are not compared: their US units depend on the form. The formula sold in Europe under the same name may differ.

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.
