The concentrations of 25-hydroxyvitamin D (25-OHD), vitamin A and vitamin E were measured in serum samples of Finnish and Floridian women; the samples were collected in spring. The Floridians had twice as much 25-OHD in serum as the Finns, but the levels of the two other fat-soluble vitamins were equal. Thus, in Florida there is very little risk for vitamin D deficiency, and vitamin A and E status seems to be unaffected by differences in dietary habits.
