Metformin is clearly PROVEN to BOTH prevent and delay progress to diabetes.
It’s silly to not try it.
It is taken orally and takes a while to build up to the optimal dose.
It can create gut issues in those with sensitive stomachs. So it does come in a compounded cream form, but most docs don’t know about this.
Berberine herbs have been shown in randomized trials to work comparably to metformin so you can try those, too.
Metformin has also repeatedly been shown to lengthen telomeres. So it is also an anti-aging tool.
So get with the program if you are one of the multi-millions that is pre-diabetic.
