The intake recommendations (D-A-CH reference values) of the German Nutrition Society (DGE) presented below are aimed at healthy people of normal weight. They do not refer to the supply of sick and convalescent people. Individual requirements may therefore be higher than the DGE intake recommendations (e.g., due to dietary habits, consumption of stimulants, long-term medication, etc.).

As part of the standardization of European regulations, valid Recommended Daily Allowances (RDAs) were issued in the European Union (EU) and became mandatory for nutrition labeling in 1990 in Directive 90/496/EEC. An update of this directive took place in 2008. In 2011, the RDA values were replaced by NRV values (Nutrient Reference Value) in Regulation (EU) No. 1169/2011. The NRV values indicate the amount of vitamins, minerals and trace elements that an average person should consume daily to meet their needs.
| Vitamin | Name | NRV |
| Vitamin C | Ascorbic acid | 80 mg |
Caution. An NRV is not an indication of maximum amounts and upper limits. The NRV values also do not take into account gender and age – see above under recommendations of the German Nutrition Society (DGE) e. V..
