Vitamin D and its role during pregnancy in attaining optimal health of mother and fetus.
Study Goal
The researchers aimed to evaluate the role of vitamin D in calcium metabolism, bone health, and immune function, with a focus on its effects during pregnancy.
Results Summary
The study confirms vitamin D's undisputed role in calcium metabolism and bone health but highlights debate over its immune function benefits. Recent clinical trials in the U.S. provide emerging data on vitamin D supplementation during pregnancy, though clear-cut benefits remain uncertain.
Population

Despite its discovery a hundred years ago, vitamin D has emerged as one of the most controversial nutrients and prohormones of the 21st century. Its role in calcium metabolism and bone health is undisputed but its role in immune function and long-term health is debated. There are clear indicators from in vitro and animal in vivo studies that point to vitamin D's indisputable role in both innate and adaptive immunity; however, the translation of these findings to clinical practice, including the care of the pregnant woman, has not occurred. Until recently, there has been a paucity of data from randomized controlled trials to establish clear cut beneficial effects of vitamin D supplementation during pregnancy. An overview of vitamin metabolism, states of deficiency, and the results of recent clinical trials conducted in the U.S. are presented with an emphasis on what is known and what questions remain to be answered.
