Story summary

Researchers at Baylor College of Medicine found that metformin lowers blood sugar by targeting the brain's Rap1 protein in the ventromedial hypothalamus (VMH).
This challenges the belief that metformin primarily functions in the liver and gut.
Lower doses of metformin can activate brain cells to effectively reduce blood sugar levels.
Future studies may investigate metformin's additional benefits for brain health.
