Low prenatal vitamin D status may also increase susceptibility to such diseases in later life via specific target organ effects and/or through changes to the developing immune system. Maternal vitamin D supplementation during pregnancy could be an important public health measure to decrease risk of a range of chronic diseases, but further research is required to clarify beneficial and adverse effects of high prenatal vitamin D.Keywords: 25 hydroxyvitamin D; vitamin D; asthma; autism; bone; brain tumor; cardiovascular risk; central nervous system disease; chronic disease; Crohn disease; diet; epilepsy; human; infant; insulin dependent diabetes mellitus; metabolic syndrome X; multiple scle Chronic disease; Fetus; Ultraviolet radiation; Vitamin D200810.1111/j.1753-4887.2008.00126.x2016-02-24
