  Purpose

The aims of the present study are to evaluate the concentrations of vitamin D in the plasma and of calcium in the plasma and in the urine as well as to evaluate bone mineral density using peripheral quantitative computed tomography (pQCT), after supplementation of vitamin D with 30µg (1200 IU) and 40µg (1600 IU), in comparison with currently recommended supplementation of vitamin D with 10µg (400 IU). In this pilot study supplementation is given to infants from 2 weeks of age to 3 months of age.

Primary Outcome Measures:
  • S-25OHD concentration after vitamin D supplementation to infants [ Time Frame: after 10 weeks of supplementation ] [ Designated as safety issue: No ]
    The primary endpoint is the concentration of 25OHD in serum after daily supplementation with vitamin D (10µg / 30µg / 40µg orally). Vitamin D supplementation is given to infants from 2 weeks of age to 3 months of age.


Secondary Outcome Measures:
  • concentration of calcium in the plasma and in the urine [ Time Frame: after 10 weeks of supplementation ] [ Designated as safety issue: Yes ]
    Incidence of hypercalcemia and hypercalciuria in infants after daily supplementation with vitamin D (10µg / 30µg / 40µg orally).

  • bone mineral density [ Time Frame: after 10 weeks of supplementation ] [ Designated as safety issue: No ]
    Measurement of bone mineral density using peripheral quantitative computed tomography (pQCT), after daily supplementation with vitamin D (10µg / 30µg / 40µg orally).

Detailed Description:

Vitamin D deficiency is common around the world. In Finland vitamin D levels are low in all age groups. Especially infants are predisposed to vitamin D deficiency. Partly this is due to low exposure to sunlight but mainly it is due to low dietary intake of vitamin D. Vitamin D prophylaxis was introduced in Finland in the 1950´s to overcome rickets. However, the recommended dose has decreased from 50µg (2000 IU) in the 1960´s to 10µg (400 IU) from beginning of the 1990´s. The serum concentration of 25-hydroxyvitamin D (S-25OHD) is used as a marker of vitamin D status in the body. Although there is no consensus of optimal concentration of S-25OHD, it has been proposed that concentrations lower than 50 nmol/l indicate deficiency. According to recent findings on 25-OHD concentrations in Finnish children, currently recommended intake of vitamin D is inadequate.
