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
