Participant exclusion criteria
1. Breast feeding
2. Pregnancy or desire to become pregnant within three years
3. Transplant listed patients or transplant recipients
4. Previous gastroscopy proven oesophageal abnormalities

8. Biochemical evidence of vitamin D deficiency at the screening visit (25-hydroxyvitamin D level <10 ng/ml and an elevated parathyroid hormone [PTH])
9. Long term oral corticosteroid use (defined as daily oral corticosteroid use for >6 weeks at the time of recruitment or the likelihood of
requiring prolonged oral corticosteroid use at the time of recruitment)
