If this product were sold in France
- Dose déclarée au-delà d'une limite
Vitamine D: up to 25 µg a day according to the label (at most 1 serving a day), above the maximum dose of 5 µg set in France for a food supplement (2006 Order, not revised since November 2006).
Source: French orders of 9 May 2006 and 14 November 2006 as published in the Official Journal (maximum daily doses), arrêté du 9 mai 2006, annexe III.
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.
