 The fortification of milk with vitamin D was also adopted in Europe; however, the process was not closely monitored, and in Great Britain it caused an outbreak of vitamin D intoxication, or hypercalcemia, the clinical manifestations of which are loss of appetite, lethargy, excessive thirst and polyuria, nausea and vomiting, constipation, and muscle weakness, and renal failure if the hypercalcemic state is unrecognized and prolonged. This outbreak led to the banning of the vitamin D fortification of milk in most of Europe. The fortification of milk with vitamin D was also adopted in Europe; however, the process was not closely monitored, and in Great Britain it caused an outbreak of vitamin D intoxication, or hypercalcemia, the clinical manifestations of which are loss of appetite, lethargy, excessive thirst and polyuria, nausea and vomiting, constipation, and muscle weakness, and renal failure if the hypercalcemic state is unrecognized and prolonged.

 If the optimal serum 25(OH)D level for skeletal health is 30 ng/mL or greater, then vitamin D insufficiency is widespread, affecting about 75% of adults based on a recent survey of more than 20,000 Americans. However, after a comprehensive analysis of existing research studies, the Institute of Medicine recently concluded that nearly all individuals are vitamin D replete when their 25(OH)D levels are 20 ng/mL or greater. Furthermore, two recent publications challenge the belief that 25(OH)D levels greater than 30 ng/mL are optimal for bone health. In a randomized, placebo-controlled trial, high-dose, once- yearly vitamin D therapy increased the incidence of fractures and falls. The second study reported that high- dose vitamin D did not reduce levels of parathyroid hormone or bone resorption among adults with 25(OH)D levels less than 32 ng/mL at baseline. It is time to question whether serum 25(OH)D levels of 30 ng/mL or greater are necessary for all individuals. If the optimal serum 25(OH)D level for skeletal health is 30 ng/mL or greater, then vitamin D insufficiency is widespread, affecting about 75% of adults based on a recent survey of more than 20,000 Americans.

-In Europe, fortification with 'vitamin' D varies. In some countries, the level of fortification can be quite low, at least in comparison to other developed countries. However, it is common practice, especially in Scandinavian countries to give children cod liver oil.  One Finnish study of children born in 1966 found that between 74 and 88% of their mothers reported giving them cod liver oil.(({{pubmed>long:15699498}}))+In Europe, fortification with 'vitamin' D varies.
