Study Arms:
- Vitamin D3 6000 IU (Type: EXPERIMENTAL): 6000 IU of vitamin D3 by mouth daily until the subject's serum 25(OH) level is ≥ 40ng/mL at which point the supplementation dose is reduced to 4,000 IU/day. Note: Subjects weighing \<40 kilograms (kg) at study entry will receive their dose five days a week and all other subjects seven days a week.
