|The typical daily amounts of vitamin D we absorb from food and supplements can be counted in the hundreds of international units (IU) while the amounts we absorb from sunlight can be counted in the thousands of IU.|
The most common misunderstanding about vitamin D deficiency is that it is not a health issue. In fact in United States the CDC reported 32% of all children and adults are at risk for vitamin D deficiency. Studies in Australia reported that at least 40% of children and adults are at risk for vitamin D deficiency.
Pregnant women are at high risk for vitamin D deficiency. Our study reported that women who took a prenatal vitamin and drank 2 glasses of milk a day thus taking 600 IUs of vitamin D daily that 76% of them were vitamin D deficient at that time they gave birth and 81% of their newborns were also vitamin D deficient.
