EFSA has launched an open consultation on its draft scientific opinion on dietary reference values for vitamin C. The document proposes dietary reference values for vitamin C for adults, infants and children, and pregnant and lactating women. The highlights considered are:
The Panel concludes that an Average Requirement (AR) and a Population Reference Intake (PRI) for vitamin C can be derived for adults and children based on vitamin C status, and for pregnant and lactating women based on estimation of additional needs and factorial calculation of losses in breast milk, respectively.
For infants aged 7-11 months, the Panel retains the PRI set by the SCF (1993), i.e. 20 mg/day, as no suitable evidence has emerged since the previous assessment.
The Panel also considered several health outcomes that may be associated with vitamin C intake; however, the available data were considered insufficient for the setting of DRVs.
| PRI (mg/day) | ||
| Age | Males | Females |
| 7-11 months | 20 | 20 |
| 1-3 years | 20 | 20 |
| 4-6 years | 30 | 30 |
| 7-10 years | 45 | 45 |
| 11-14 years | 70 | 70 |
| 15-17 years | 100 | 90 |
| ≥ 18 years | 110 | 95 |
| Pregnancy | - | +10 |
| Lactation | - | +75 |
* Average Requirement (AR): nutrient intake value that is estimated to reach the requirements in 50 per cent of people in a specific group, usually defined by age and sex.
