Overview Gut and vitamin D contains the following summary
- Gut problems result in reduced absorption of Vitamin D, Magnesium, etc.
- Celiac disease has a strong genetic component.
- Most, but not all, people with celiac disease have a gene variant.
- An adequate level vitamin D seems to decrease the probability of getting celiac disease.
- Celiac disease causes poor absorption of nutrients such as vitamin D.
- Bringing the blood level of vitamin D back to normal in patients with celiac disease decreases symptoms.
- The prevalence of celiac disease, not just its diagnosis, has increased 4X in the past 30 years, similar to the increase in Vitamin D deficiency.
- Review in Nov 2013 found that Vitamin D helped
- Many intervention clinical trials for vitamin D to prevent or treat Gut problems (93 trials listed as of Jan 2017)

Emerging data suggest that vitamin D has a significant role in inflammatory bowel disease (IBD). Prospective data evaluating the association of vitamin D serum status and disease course are lacking. We sought to determine the relationship between vitamin D status and clinical course of IBD over a multiyear time period.
IBD patients with up to 5-year follow-up from a longitudinal IBD natural history registry were included. Patients were categorized according to their mean serum 25-OH vitamin D level. IBD clinical status was approximated with patterns of medication use, health-care utilization, biochemical markers of inflammation (C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR)), pain and clinical disease activity scores, and health-related quality of life.
A total of 965 IBD patients (61.9% Crohn's disease, 38.1% ulcerative colitis) formed the study population (mean age 44 years, 52.3% female).
Among them, 29.9% had low mean vitamin D levels.
Over the 5-year study period, subjects with low mean vitamin D required significantly more
- computed tomography scans,
- emergency department visits,
- hospital admissions, and
compared with subjects with normal mean vitamin D levels (P<0.05).
Moreover, subjects with low vitamin D levels had worse
- disease activity scores, and
- quality of life (P<0.05).
Finally, subjects who received vitamin D supplements had a significant reduction in their health-care utilization.
Low vitamin D levels are common in IBD patients and are associated with higher morbidity and disease severity, signifying the potential importance of vitamin D monitoring and treatment.
