Welcome to our podcast, where today we're exploring an intriguing topic: Metformin and its potential role in anti-aging.

Marc Provissiero, a movie producer in his mid-50s, turned to metformin after finding his blood sugar levels approaching prediabetic range, despite leading a healthy lifestyle. As he puts it, “the hope is that this is going to lead to a greater number of healthy years.” Metformin, traditionally used to treat Type 2 diabetes, is being investigated by some doctors for its promise in delaying chronic diseases and enhancing longevity.

While existing research on metformin’s anti-aging effects is limited and sometimes conflicting, early findings suggest it may regulate hormones and reduce cell damage—key processes in aging. However, as Dr. Richard Miller notes, the evidence remains "weak" and requires deeper investigation.

Currently, a significant human trial, the Targeting Aging With Metformin trial, is delayed, leaving many eager for clarity on its efficacy. Meanwhile, patients like Provissiero are taking what he calls a "leap of faith," believing the potential benefits outweigh the risks.

With metformin costing only $10 to $30 a month, it's an appealing option for many. But as Dr. Miller cautions, we must prove its effectiveness, particularly for those without diabetes markers. It's clear that while metformin offers fascinating possibilities, comprehensive studies are essential to validate its benefits for longevity.
