Micronutrients & recovery
Vitamin A and Vitamin D supplementation can improve intestinal barrier function and reduce inflammation in patients with Inflammatory Bowel Disease (IBD).
If you have IBD, discuss Vitamin D supplementation (e.g., 2000 IU/day) with your doctor. Evidence suggests it may help improve gut permeability and reduce inflammation markers like CRP.
GoodSupportsHIGH confidence
short-term treatment with 2000 IU/day of vitamin D has been shown to improve small intestinal and colonic paracellular permeability and to reduce CRP plasma levels in patients with IBD
Why this rating
Based on human clinical trials (though described as 'few'), showing specific improvements in permeability and CRP.
