(1) 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. (2) When the median intake of the population >the AI, the risk for inadequate intake is low. No statement (ns) can be formulated on the adequacy of vitamin D when the median intake <AI. EAR: estimated average requirement; UL: upper intake level; AI: adequate intake.
