Vitamin D concentrations in Finnish adults have risen clearly in recent decades, according to a large-scale follow-up study conducted at the University of Oulu, Finland. This favorable development might be explained not only by the national vitamin D intake recommendations but also by the food fortification program, which has led to the addition of vitamin D to liquid dairy products and fat spreads. This finding reinforces the perception of the benefits of the use of vitamin D supplements and the food fortification program.
