>There is some evidence metformin may be helpful in extending lifespan, even in otherwise healthy people. It has received substantial interest as an agent that delays aging, possibly through similar mechanisms as its treatment of diabetes (insulin and carbohydrate regulation). This is controversial, and an area of active research.[61][62]
If you're overweight, tell your doctor you want help with your appetite. Otherwise, say you want metformin for its cancer prevention and anti-aging effects.
Metformin is safe and it almost universally improves health and well-being.
Your doctor knows this, and she'll gladly prescribe it.
If your doctor gladly prescribes anything you just walk in and ask for by name and dosage and doesn't have a green cross symbol outside their office, then I'd highly suggest seeking out a new doctor.
I'm saying it's likely your doctor will be willing to prescribe METFORMIN (that drug, in particular) for off-label use if you ask.
Dumb question: How? I'm reasonably certain my GP would not be amenable to being asked to prescribe drugs for off-label use.
