Metformin

I think you will find Metformin does neither of those things really. I'd like to see the evidence that Metformin helps insulin absorption unless you have insulin resistance i.e. are overweight. Metformin can depress the appetite a bit but not a lot really. I take Metformin with my insulin partly to keep my DN happy (!). Research data shows it improves blood sugar just a little and apparently has other protective effects. I think many are prescribed both. A low-carb diet as always help control weight and avoid insulin resistance.
