EFSA confirmed that dietary reference values for vitamin K will remain fixed at the same level they were initially set at almost 25 years ago, after a review of new evidence and stakeholder comments found no evidence to warrant a change of stance.
The Panel on Dietetic Products, Nutrition and Allergies (NDA) considered comments and input on the draft scientific opinion in early 2017 before deciding to maintain the dietary reference values established by the Scientific Committee for Food in 1993.
Consequently, the NDA Panel defined daily adequate intakes (AIs) for vitamin K remain as follows:
- 10 micrograms for infants aged 7-11 months
- 12 micrograms for children aged 1-3 years
- 20 micrograms for children aged 4-6
- 30 micrograms for children aged 7-10
- 45 micrograms for children aged 11-14
- 65 micrograms for adolescents aged 15-17 and
- 70 micrograms for adults including for pregnant and lactating women
** This article has been updated after it was pointed out that the intake levels were stated as mg, which is generally shorthand for milligrams, while the EFSA values were in fact set out in micrograms. NutraIngredients has also notified EFSA, since an EFSA statement also used mg to refer to micrograms.
