Measure
Low Dose Vitamin D
Patients will be given 400 IU cholecalciferol once daily for 30 days. 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. Cholecalciferol 400 IU
High Dose Vitamin D
Patients will be given cholecalciferol 10,000 IU daily for 30 days. 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. Cholecalciferol 10,000 IU

modified Harvey-Bradshaw is a disease assessment scale. 0 is the lowest score and would be considered remission. Scale ranges to over 16 (upper limit is defined by the number of bowel movements in the prior day) with numbers over 16 being severe disease. A positive change (such as that indicated below) therefore references slightly worsening disease while a negative change references improving disease. Originally planned to collect at Day 180 and Day 360. Only 1 subject remained in the study to Day 180 so that data is presented here. 1 subject had an increase of 1 unit on the modified HBI.
