Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a neurological disease. Currently there is no effective treatment for ME/CFS due to unclear etiology of the disease. The aim of this randomized double-blind placebo-control clinical trial is to study the efficacy of the probiotic food supplement "GutMagnific" in ME/CFS and comorbid gastrointestinal complications. The outcome of the study will be assessed based on the data from different self-reporting questionnaires and intestinal microbial flora analysis.


Myalgic Encephalomyelitis/ Chronic Fatigue Syndrome (ME/CFS) is a neurological disease with different symptoms such as fatigue. Symptoms get worse by physical or mental exertion which usually persists for more than 24 hours (post-exertional malaise, PEM). ME/CFS is often characterized by reduced functional capacity, worsening social relationships and reduced ability to cope with work or study.

The exact cause of the ME/CFS is presently unknown however a history of viral infection is common among ME/CFS patients. Prolonged post viral fatigue can develop into a chronic illness and ME/CFS. Current research strongly suggests involvement of gastrointestinal tract and gut microflora disturbances in the pathogenesis with strong evidence supporting the role of imbalance of gut microflora, damaged gut barrier functions and dysfunctional immune responses. There are some features shared with gastrointestinal conditions like irritable bowel syndrome (IBS). GutMagnific is an evidence-based probiotic food supplement, scientifically designed to be effective in correcting imbalances of the gut microflora, repairing a damaged gut barrier and reducing inflammation. The strain combination in GutMagnific has been carefully designed for its efficacy in IBS and therefore it can be reasonably expected to be also effective in ME/CFS.
