NCT02535910

Brief Summary

This study aims to compare the acute effect of consuming milk and butter fortified with either vitamin D3 or 25 (OH) D3 on serum/plasma vitamin D status in humans. In addition, the effect of vitamin D3 or 25 (OH) D3 in milk and butter on certain CVD risk markers and cognitive function will be examined.

Outcome Measures

Primary Outcomes (2)

  • Change from baseline in the concentrations of vitamin D3, 25(OH)D3, 1, 25(OH)2D3 of the blood

    Acute study: measured at 0 (baseline), 30, 60, 90, 120, 180, 240, 300, 360, 420, 480 min and 24 hour

  • Change from baseline in the concentrations of vitamin D3 and 25(OH)D3 of the chylomicron

    Acute study: measured at 0 (baseline), 3, 6, 8 hour

Secondary Outcomes (8)

  • change from baseline in vascular reactivity measured by Endo-PAT

    Acute study: measured at 0 (baseline) and the 24 hour

  • change from baseline in vascular reactivity measured by digital volume pulse (DVP)

    Acute study: measured at 0 (baseline), 120, 240, 360, 480 min and 24 hour

  • change from baseline in plasma lipids (primarily triacylglycerol, apolipoprotein B, apolipoprotein B-48, apolipoprotien B-100, total-cholesterol, HDL-cholesterol, non-esterified fatty acids)

    from 0 to 24 hour, but different measured time points for diferent lipids

  • change from baseline in markers of insulin resistance (glucose and insulin)

    Acute study: measured at 0, 30, 60, 90, 120, 180, 240, 300, 360, 420, 480 min and 24 hour

  • change from baseline in nitric oxide

    Acute study: measured at 0, 60, 120, 240, 360, 480 min and 24 hour

  • +3 more secondary outcomes
