Vitamin D status and the current policies to achieve adequate vitamin D intake in the Nordic countries

Although Nordic countries share common nutrition recommendations, there are differences between the countries in the implementation of the recommendations and the policies and practices to achieve adequate vitamin D intake and status. Vitamin D fortification policies can be mandatory or voluntary and widespread, moderate or non-existent. Vitamin D supplementation recommendations also differ, ranging from all age groups being recommended to take supplements to only infants. In the general population of the Nordic countries, vitamin D status and intake are suboptimal, but better than in the risk groups that are not consuming vitamin D supplements or foods containing vitamin D. Non-Western immigrant populations of all Nordic countries share the problem of vitamin D insufficiency or even deficiency. There is a growing need for wider Nordic collaboration studies as well as for strategies to improve vitamin D status, especially in risk groups.
