Fifty-three, fibromyalgia syndrome participants were randomized to receive either: 1) probiotic 4×1010 CFUs per day 2) 10 g dose prebiotic (inulin) per day or 3) placebo for 8 wk. Fibromyalgia Impact Questionnaire (FIQ), Visual Analogical Pain Scale (VAS), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Pittsburg Sleep Quality Index (PSQI) and quality of life (SF-36) were measured during the baseline, 4 weeks and 8 weeks intervention phases.
