I’ve been taking metformin for life extension for about 5-10 years. It’s dead cheap ranging from free at some pharmacies to like $5 for six months. And I haven’t had any discernible side effects.
What’s funny though is that my insurance and some health systems now think I have diabetes and are sending me mailers and calls for diabetes interventions. So I guess their CDS is pretty simple and just looks for rxnorm metforming scripts for “undiagnosed” diabetes. I don’t have diabetes and don’t have any of the clinical markers that would indicate diabetes or prediabetes.
Just a fun fact.
