Do we know how much metformin is effective for its anti aging property. Does one need a full 500mg/day dose? Will 250 mg suffice to achieve pro AMPK activity?

Most think of metformin as a glucose-lowering medicine. I think it impacts the key signaling pathways at lower doses. I have prediabetes and I take 500mg twice a day. I have no side effects at all.

I do not have prediabetes. I hope to persuade my PCP to order it for me. We shall see as it would be for an “off label” indication.
