There are some evidence that Vitamin D supplementation may be beneficial for patients with irritable bowel syndrome (IBS). The aim of this study was to evaluate the effects of Vitamin D supplementation on symptoms and quality of life (QOL) in patients with IBS. Methods: In a randomized, double blind, placebo controlled clinical trial, 116 patients with IBS were supplemented weekly with either a pearl of 50,000 IU Vitamin D or an identical pearl of placebo containing medium chain triglyceride for 6 weeks. Results: Mean age of patients was 42.24 ± 12.26, and 40.06 ± 13.37 in Vitamin D and placebo groups, respectively. Dietary intakes were similar between and within groups. Serum concentration of 25 hydroxy Vitamin D increased significantly from 21.10 ± 5.23 to 36.43 ± 12.34 in the Vitamin D group (P < 0.001), while it was not significantly different before and after the trial in placebo group. The IBS symptoms severity scores (SSSs), disease specific QOL, and total score were evaluated at weeks 0 and 6. IBS SSS, IBS QOL, and the total score were improved significantly more in Vitamin D group in comparison to the placebo group (P < 0.05). Conclusions: This study indicates that Vitamin D therapy can improve the severity of symptoms and QOL in patients with IBS; however, the long term effects remained to be elucidated.
