  • Vitamin D deficiency (< 25 nmol/l)
  • Age 15 or above

Exclusion criteria

  • Travel south of 45 degrees latitude during the trial.
  • Ongoing treatment with vitamin D supplementation.
  • Intake of light sensitive medicine, such as tetracyclins.

Treatment and study plan

Narrowband UVB

Radiation

UVB 3 times a week

Other names: NB-UVB

Vitamin D and calcium

Dietary Supplement

1 daily tablet of 1600 IU vitamin D3 and 1000 mg calcium

Other names: Vitamin D supplementation

Primary outcomes

  1. Vitamin D (nmol/l).

    Time frame: Week 0

    Vitamin D was measured in a bloodsample to determine baseline status.

  2. Vitamin D (nmol/l)

    Time frame: Week 3

    Vitamin D was measured in a bloodsample to follow the change from baseline in vitamin D level at week 3.

  3. Vitamin D

    Time frame: Week 6

    Vitamin D was measured in a bloodsample to follow the change from baseline in vitamin D level at week 6.

Secondary outcomes

  1. Parathyroid hormone (pmol/l).

    Time frame: Week 0, 3 and 6.

    To investigate whether parathyrodiea hormone changes during the study.

  2. Albumin (g/l).

    Time frame: Week 0, 3 and 6.

    To investigate whether albumin changes during the study.

  3. Calcium (mmol/l)

    Time frame: Week 0, 3 and 6.

    To investigate whether calcium changes during the study.

  4. Hemoglobin A 1c (percentage HbA1c of total hemoglobin).
