The purpose of this study is to analyse the effect of a probiotic supplement on functional intestinal symptoms among subjects diagnosed with irritable bowel syndrome (IBS).
The aim of the intervention is to analyse the effect of a probiotic supplement in a dose-responsive set up on functional intestinal symptoms among subjects diagnosed with IBS according to Rome III criteria. Subjective assessment of bowel symptoms, quality of life, anxiety and depression and adequate relief will be assessed as with questionnaires as outcome measures. The intestinal microbiota will be analysed from faecal samples.
