Researchers at Mayo Clinic in Jacksonville, Florida, have found that vitamin D supplementation may facilitate rebalance the immune system’s response to gut bacteria in people with inflammatory bowel disease, according to a study published in ‘Cell Reports Medicine’.
The study focused on 48 individuals with inflammatory bowel disease who had low levels of vitamin D. Over a 12-week period, participants received weekly vitamin D supplements. Researchers observed that the supplementation was associated with improved immune activity related to intestinal bacteria.
Inflammatory bowel disease, which includes Crohn’s disease and ulcerative colitis, involves an abnormal immune response to normally harmless gut bacteria. This reflects a disruption in immune tolerance, a key mechanism for maintaining intestinal balance.
“This study suggests that vitamin D may help rebalance how the immune system recognizes intestinal bacteria,” said John Mark Gubatan, M.D., a gastroenterologist at Mayo Clinic in Florida and the study’s lead author.
The findings highlight a potential connection between vitamin D, immune function, and gut microbiota, offering insight into how nutritional interventions might influence digestive health in individuals with chronic intestinal conditions.
