New Study Reveals How Vitamin D Could Calm Gut Inflammation

A Mayo Clinic study suggests vitamin D supplements may alter immune responses to gut bacteria in people with inflammatory bowel disease.

In 48 patients with low vitamin D, 12 weeks of supplementation was linked to changes in immune markers, signaling, and inflammation-related measures.

The effects appeared connected to the gut microbiome and may help restore immune balance in Crohn's disease and ulcerative colitis.

Researchers say the findings are promising but early, and larger controlled trials are needed before any treatment conclusions.
