Clinical trials

The aim of this clinical trial is to gain a better understanding of the effect of Vitamin D supplementation on disease activity and overall health. The main questions it aims to answer are: 1. What proportion of IBD patients adhere to Vitamin D supplement recommendations over a 12-month period? 2. Is the ASK-12 Questionnaire valid in measuring adherence among IBD patients? 3. Does the severity of a patient's Crohn's disease effect overall adherence, over a 12-month period? 4. Does the severity of a patient's Ulcerative Colitis disease effect overall adherence, over a 12-month period? 5. Does Vitamin D supplementation affect the health-related Quality of Life for IBD patients? 6. Is 2,000 IU/Day an effective dose to sustain appropriate blood Vitamin D levels among previously Vitamin deficient IBD patients? Participants will: * Take 2000 IU of Vitamin D every day for the next 12 months * Complete 2 surveys, bloodwork and a fecal calprotectin test at the initial, visit, 6 month follow up and 12 month follow up
