Primary Outcome Measures:
- Change in 25-OH Vitamin D Blood Levels over 60 days [ Time Frame: 2 years ] [ Designated as safety issue: No ]Subjects will have their baseline 25-OH Vitamin D levels drawn. They will then take Omeprazole 20mg for 60 consecutive days, then have blood samples drawn to measure their 25-OH Vitamin D.
