Role of Vitamin D receptor and vitamin D binding protein restriction fragment length polymorphisms in determining dose response to vitamin D: a randomized double blind placebo controlled trial
Serum 25-hydroxyvitamin D (25OHD) is considered to be the best biomarker of vitamin D status. Besides the dietary intake of vitamin D and exposure to sunlight, there are other factors that affect serum 25OHD such as weight, race, sex, binding protein and the effect of vitamin D receptor (VDR) and …
