Since the beginning of the 21st century, interest in vegan diets has been rapidly increasing
in most countries. Misconceptions about vegan diets are widespread among the general …

A large body of research shows an association between higher body weight and low vitamin
D status, as assessed using serum 25-hydroxyvitamin D concentrations. Vitamin D can be …

The determination of vitamin D metabolites as status marker or for diagnostic purposes is
almost entirely conducted from blood serum or plasma. Other biological matrices, however …

The present study systematically compares the sensitivity and selectivity of the analysis of
multiple vitamin D metabolites after chemical derivatization using different reagents for liquid …

The majority of circulating 25-hydroxyvitamin D (25 (OH) D) is protein bound and perhaps
less available than the free fraction of 25 (OH) D; therefore, researchers have proposed that …

Liquid chromatography/tandem mass spectrometry (LC–MS/MS) is widely used to determine
vitamin D3 metabolites in biological samples. The ionization efficiencies of these …

Fat-soluble vitamins, including vitamins A, D, E, and K, are essential for maintaining normal
body function and metabolism. Fat-soluble vitamin deficiency may lead to bone diseases …

Vitamin D has received significant attention from clinical societies, researchers, and the
general population in recent years. While 25-hydroxyvitamin D (25 (OH) D) is the most …

Vitamin D is essential for optimal bone health, and vitamin D deficiency has been associated
with an increased risk of adverse pregnancy, growth and developmental outcomes. In early …

Quantitative analysis of the biologically-active metabolites of vitamin D (VitD), which are
