Vitamin D may help reduce the symptoms of Crohn's disease, a condition which causes abdominal pain, diarrhoea, fatigue and can seriously impact on a sufferer's life.
The findings come from a study led by Prof Maria O Sullivan and Tara Raftery of the Department of Clinical Medicine, Trinity Centre for Health Sciences, St James's Hospital, Dublin.
In a double-blind randomised placebo-controlled study, the authors assigned 27 patients in remission to 2000 IU/day vitamin D supplementation or placebo for three months.
They found that patients treated with the supplementation were more likely to maintain their intestinal permeability, whereas this deteriorated in the placebo group.
