Tolerability and Risk of Adverse Events With a Probiotic Supplement

The butyrate-producing bacterium Faecalibacterium prausnitzii is abundant in the human bowel and can make up to 5% of the gastrointestinal flora in healthy individuals. A reduced presence of it has been associated with an imbalance in the gastrointestinal flora of metabolic syndromes such as type 2 diabetes, fat liver, and in inflammatory bowel disease. The present double-blind, placebo-controlled, randomized study is designed to investigate if dietary supplementation with F.prausnitzii (combined with D. piger) once a day for 8 consecutive weeks is tolerated compared to placebo and if it can affect the metabolism in a positive way.
