Study Arms:
- Low Dose Vitamin D (Type: ACTIVE_COMPARATOR): Patients will be given 400 IU cholecalciferol once daily for 30 days. \<-THIS IS THE Active Comparator Intervention. To maintain the blind, a random few will be given another round at the 30 day mark. For patients who enroll in the summer, a random few will again receive 400 IU cholecalciferol in March.
- High Dose Vitamin D (Type: EXPERIMENTAL): Patients will be given cholecalciferol 10,000 IU daily for 30 days. \<-THIS IS THE INTERVENTION. At that point, if their vitamin D levels remain below 50 ng/ml, the 30 day course will be repeated. For patients who enroll in the summer, levels will be rechecked in March and if \<50 ng/ml, a 30 day course will be administered.

Based on this trial design, predict the completion outcome and termination type (if applicable).
