    Child assessed at 3 years of age

Secondary Outcomes (1)

  • Number of Mothers Who Developed Side Effects From Vitamin D

    During pregnancy and the 3 years of the child's development

Study Arms (1)

Intervention during pregnancy

EXPERIMENTAL

5000 IU Vitamin D3 to be given to the mother during pregnancy. 7000 IU Vitamin D3 to be given during breast feeding if breast feeding. If not breastfeeding, infant to be given 400 IU Vitamin D3 during first year of age, then increased to 1000 IU D3 until completion of research trial.

Drug: Vitamin D3

Interventions

5000 IU D3 capsule oral/day for entire pregnancy. 7000 IU D3/day during breastfeeding. If not breast feeding, baby gets 400 IU D3/day. Baby increased to 1000 IU D3/day at one year of age.

Also known as: Cholecalciferol
