Supplemental Vitamin D Increased Serum Total 25-Hydroxyvitamin D in the US Adult Population During 2007 –2014

ConclusionsAfter adjusting for vitamin D supplement dose, the overall adjusted increase in 25(OH)D was no longer statistically significant, suggesting that changes in US adults ’ 25(OH)D concentrations between NHANES periods 2007–2010 and 2011–2014 may primarily be associated with changes in vitamin D supplementation.
