In this sense, besides the use of supplements in some
groups that have a high risk of a deficiency of vitamin D,
it might be appropriate to ensure the mandatory fortification
of certain food items as a strategy for improving
vitamin D status among population. The results of the
present study may be helpful to health authorities when
assessing the suitability of establishing mandatory fortification.
However, fortified foods and supplements should
be used carefully and should not replace a varied and
adequate diet.
