About the thesis

Low vitamin D status is prevalent during winter among children living at northern latitudes. However, the exact amount of vitamin D required by children is currently unknown. Moreover, there is a knowledge gap when it comes to the potential health consequences of a low vitamin D status in children during winter.

In this PhD thesis, the relation between vitamin D intake and the concentration of vitamin D in the blood is examined, in order to estimate the requirement of vitamin D in children. Moreover, it is investigated if winter vitamin D supplementation has an effect on children’s muscle strength and selected growth factors.

The PhD thesis shows that muscle strength in healthy children aged 4-8 years is not influenced by a daily vitamin D supplementation during winter; however, the concentration of some growth factors is affected.
