(1) AI for vitamin K is 12 μg/day in children aged 1–3 years and 20 μg/day in children aged 4–6 years old. The UL for vitamin K is 200 μg/day in children aged 1–3 years and 300 μg/day in children aged 4–6 years old. (2) When not enough evidence is available to set an EAR, an AI is set. The AI is based on the average intake of an apparently healthy population. (3) When the median intake of the population lies above the AI, the risk for inadequate intake is low. Since the distribution of requirements is not known, no statement (ns) can be formulated on the adequacy of vitamin K when the median intake is lower than the AI. (4) ic: inconclusive within a certain age-group. EAR: estimated average requirement; UL: upper intake level; AI: adequate intake.
