Vitamin D status and supplementation in pediatric gastrointestinal disease

Purpose. To evaluate vitamin D status and supplementation in the pediatric population with common gastrointestinal diseases. The literature was searched for studies on vitamin D status in children with inflammatory bowel disease (IBD), celiac disease, and liver disease. Vitamin D supplementation in healthy children was also reviewed. Conclusions. Those with gastrointestinal diseases are more likely to have vitamin D deficiency as a result of malabsorption. Current recommendations for supplementation may be too low to achieve optimal levels. Practice Implications. It is important to monitor vitamin D levels in pediatric populations with gastrointestinal diseases and appropriately treat levels that are insufficient.
