Summary

The primary aim of the present trial is to study the effect of daily vitamin D supplementation on muscular power and force among non-western immigrants living in Oslo, Norway, and secondarily to study the effect of musculoskeletal pain and headache.

The investigators have also prespecified a number of additional research questions about anemia, metabolism and bone turnover, inflammation, diabetes, lipids, itching and kidney function, which because of multiple comparisons should be interpreted with caution unless the statistical evidence for an effect is very strong.
