INFORMATION FOR WOMEN HAVE VITAMIN D DEFICIENCY DURING PREGNANCY OR BREASTFEEDING

 

What is vitamin D deficiency?

Vitamin D deficiency is a condition in which a form of vitamin D, called 25-hydroxyvitamin D (calcidiol, 25-[OH]D), is present below a certain concentration in the blood. Some debate surrounds the appropriate cutoff level defining whether a person’s 25-(OH)D is adequate, but generally doctors use a value of 20 ng/mL (50 nmol/L). Thus, if your level is below this value, you are considered to have a vitamin D deficiency. Although called a “vitamin”, vitamin D is actually a hormone, because it is produced in the body. This happens when ultraviolet radiation (UV) in sunlight interacts with a precursor to vitamin D, called 7-dehydrocholesterol (7-DHC), in special skin cells. However, we also obtain vitamin D from the diet. Consequently, during pregnancy and throughout life, both lack of sunlight and lack of dietary vitamin D can contribute to vitamin D deficiency.
