A Trial of Vitamin D Supplements
Although scientists noted a vitamin D deficiency in irritable bowel syndrome sufferers, a new study of vitamin D supplementation showed no improvement in symptoms. The study, published in the European Journal of Nutrition, randomized 135 participants to receive daily vitamin D supplements or a placebo. Via a questionnaire, participants noted their pain severity, number of days with pain, abdominal distension severity, bowel habit satisfaction, and quality of life.
The study states, “This study found no beneft of vitamin D supplementation on either symptoms of IBS or on QoL measures using standardised assessments. In addition, we found no relationship between change in vitamin D and change in symptomology.” However, because those with IBS show an increased risk of osteoporosis and fractures, “poor vitamin D status…may contribute to the observed association with these conditions.” Those with IBS may limit their time outdoors. “IBS patients should be screened for vitamin D status and supplemented appropriately for general health reasons.”
