Metformin, the drug most often used to treat type 2 diabetes, has a greater effect on gut microbes than the disease itself. The finding, by scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, and colleagues in the EU-funded MetaHIT consortium, has implications for studies searching for links between our microbiomes and disease. Published today in Nature, the study points to new approaches for understanding how metformin works, and minimising the side effects of a drug that patients take in high doses for many years.
