Study Completion Date: December 2012
Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: vitamin D fortified fish
Human volunteers receiving vitamin D fortified fish, 4 weeks
Other: vitamin D fortified fish
fish containing vitamin D3
Other Name: intervention
Placebo Comparator: conventional fish
consumption of conventional fish , 4 weeks
Other: conventional fish
fish containing low concentrations of vitamin D3
Other Name: placebo

Detailed Description:

Study design: Human volunteers will receive conventional fish or vitamin D fortified fish for a period of 4 weeks. At baseline and after 4 weeks, 25(OH)D3 will be measured in serum as the main outcome variables. Additional outcome variables are the Ca concentration in serum, PTH concentration in serum.
