Here's a related study
Assessment of dietary vitamin D requirements during pregnancy and lactation.
Bruce W Hollis and Carol L Wagner. American Journal of Clinical
Nutrition, Vol. 79, No. 5, 717-726, May 2004.
"We are conducting an ongoing study that involves the supplementation of
lactating mothers with 2000 IU (50 µg; n = 9) or 4000 IU (100 µg; n = 9)
vitamin D/d for 3 mo. Our preliminary data show increased mean (± SD)
circulating 25(OH)D concentrations in the 2000-IU/d group (from 27.6 ±
9.8 to 36.1 ± 7.0 ng/mL) and in the 4000-IU/d group (from 32.6 ± 6.9 to
44.5 ± 11.4 ng/mL), all of which are within the normal reference range.
We note that the breastfeeding infants of these mothers have a
substantially improved nutritional vitamin D status because of the
transfer of vitamin D into the mother’s milk. Circulating 25(OH)D
concentrations in the infants of mothers receiving the 4000-IU/d dose
increased into the normal range after only 3 mo of breastfeeding."
