Primary Outcome Measures:
  • Serum-vitamin D [ Time Frame: 12 weeks after treatment start ] [ Designated as safety issue: No ]
    Levels of serum vitamin D3 and Serum -parathyroid hormone(PTH) are to be measured


Secondary Outcome Measures:
  • Muscle strengths in hands and legs [ Time Frame: 12 weeks after start of treatment ] [ Designated as safety issue: No ]

    Muscle strength in hand is measured with JAMAR dynamometer. Muscle strength in lower legs is measured with Balance test by Ekdahl.

    Quality of life questionaries will also be used.

Detailed Description:

The participants in the study have taken part in a previous screening study. They are now asked to participate in this treatment study. At a screening visit blood samples for vitamin D3 and PTH are collected. Data regarding previous fractures, life style, exposure for sun, clothes, diet, smoking and physical activities are collected. The Vitamin D value predict the treatment dose.
