Scientists at the European Molecular Biology Laboratory (EMBL) in Hamburg and Centre for Structural Systems Biology (CSSB) have uncovered how some common medications could be quietly causing vitamin B1 deficiency in our brain. This hidden but dangerous deficiency often goes undetected because it can occur even when blood levels of B1 are normal. The researchers have provided molecular insights into how specialised B1 transporter proteins allow the vitamin to cross membranes in our body and reach vital tissues and organs. They also identified several common medications that disrupt this process, which could cause hidden B1 deficiencies, and uncovered the molecular
