What is the recommended daily vitamin D supplementation for pregnant women with deficiency?

The recommended daily vitamin D supplementation for pregnant women who are found to have a deficiency is typically in the range of 1000 to 2000 IU per day. This dosage is supported by current guidelines which recognize that many pregnant women may start with low vitamin D levels due to insufficient dietary intake, limited sun exposure, or other factors affecting absorption.

During pregnancy, adequate vitamin D levels are essential not only for the health of the mother but also for the proper development of the fetus, particularly regarding bone health and immune function. When vitamin D deficiency is identified, higher doses are often recommended to quickly raise serum vitamin D levels to an optimal range, hence the recommendation of 1000 to 2000 IU per day.

This range is considered sufficiently safe and effective in addressing deficiency without the risk of toxicity, which can occur at excessively high dosages. The lower ranges provided in other options may not adequately correct a deficiency, and higher dosages such as 5000-7000 IU, while effective for some, are often reserved for more severe deficiency cases and require careful monitoring by healthcare professionals.
