Impact of 25-hydroxyvitamin D free and bioavailable fractions of vitamin D and vitamin D binding protein levels on metabolic syndrome components

摘要

IntroductionVarious forms of vitamin D and factors involved in their metabolism can play a role in the etiopathogenesis of metabolic disorders. This paper aims to define the relationship between concentration of the hydroxylated form of vitamin D (25(OH)D), the fraction of free and bioavailable vitamin D, and of vitamin D binding protein (VDBP) levels on the one hand and the prevalence of metabolic syndrome components on the other.
