Vitamin B1 stops deadly lactate production and opens the door to a new sepsis treatment
Scientists in Ghent have achieved a breakthrough in sepsis research. In a study on mice, the researchers demonstrated that vitamin B1 (thiamine pyrophosphate, TPP) restores mitochondrial energy metabolism, drastically reduces lactate production, and increases survival rates in sepsis. The study results are published in Cell Reports.

Kidney complications in diabetes often progress silently, putting patients at risk of life-threatening outcomes long before any symptoms appear. Identifying individuals with diabetes who are at risk of rapid kidney function decline or early death has challenged doctors for decades, with traditional markers like serum creatinine and urinary albumin falling short of accurately predicting these risks.

Eight different vitamins make up the B complex, and they all play crucial roles in the body, such as producing energy, keeping our nervous system healthy, and supporting cell development. If eight sounds like a lot to keep track of, it might help to know that most research focuses on five in particular: thiamine (B1), riboflavin (B2), niacin (B3), folate (B9), and cobalamin (B12).
