The nursing mother’s dietary requirement of vitamin D may be as much as 6000 IU/d daily.

In November 2010 the Institute of Medicine (IOM), the organization that reviews research and makes recommendations about vitamins and dietary supplements, issued new guidelines for Vitamin D. They recommended that pregnant and nursing women get 600 IU of Vitamin D daily. They recommended a maximum of 4000 IU daily for these women.

These doses are much lower than many other individuals and organizations have proposed in recent years. The difference has led to some discussion and controversy. The Institute of Medicine is charged with making recommendations based only on evidence, or the outcome of actual studies. They do not make recommendations based on theory or expert opinion.

The range of doses provided in the IOM recommendation is certainly large enough that it is probably safest for pregnant and nursing women to keep their Vitamin D doses between 600 IU and 4000 IU daily.
