Maternal Oral Vitamin D Supplementation Via Daily or Monthly Regimens and the Effect on Levels of Vitamin D in Human Milk and Infant Serum
Adequate vitamin D is essential for proper infant growth and development. However, human
milk is low in vitamin D, and most infants do not receive recommended supplementation. Our
aim is to assess the feasibility of providing adequate vitamin D to breastfed infants
through maternal vitamin D supplementation. Forty non-pregnant, lactating women at least
18 years of age with exclusively breastfed infants between the ages of 1 and 6 months will
be randomized to receive oral vitamin D as either 5,000 IU daily for 28 days or 150,000 IU
as a single dose. Maternal serum calcium, phosphorus, vitamin D and 25(OH)D; maternal
urinary calcium; maternal milk vitamin D and 25(OH)D will be measured on days 0, 1, 3, 7,
14, and 28 of the study; and infant serum vitamin D and 25(OH)D will be measured on days 0
and 28.
