Comment by VitaminDWiki: Finnish nutrition board apparently decided on 2,000 IU upper limit because people cannot get more vitamin D from FOOD without fortification, supplements, or sun/uv

or “it would be even harder or even impossible to fulfill it without usage of food supplements in the whole population”

Abstract: This thesis assesses clinical differences in patients with low and high vitamin D levels. The factors analyzed included the underlying disease, body size, age, ethnic background, use of vitamin D supplements and the season when the blood sample was taken. Fifty patients with the lowest and 50 patients with the highest vitamin D concentrations were selected from a cohort of 1351 chronically ill children and adolescents who had had their vitamin D status assessed at Children's Hospital.

Protective factors appeared to be the usage of vitamin D supplements and young age, especially age <2 years.

Predisposing factors included non-Finnish ethnic background and older age, especially age 12-18 years. High vitamin D values were more prevalent in the summer and autumn and low values in the winter and spring. Patients with non-Finnish background were overrepresented in the low value group.

No differences regarding the underlying diseases could be detected.

Conclusions: In the Northern latitudes UVB-radiation is insufficient for vitamin D synthesis. Vitamin D recommendations appear to be inadequate to fulfill the needs of chronically ill patients whose requirements for vitamin D are elevated compared to the general population. New guidelines for vitamin D supplementation are needed particularly for those at risk of developing vitamin D deficiency.
