I'm in my late 40s and cleared to donate in a few weeks. I've never watched my sugar intake or exercised as much as I ought, so my A1C is consistently on the edge of pre-diabetes. Last year, my GP recommended berberine. I never took it but I want to start managing my blood sugar. And yes I know diet and exercise will be needed in order to prevent or manage diabetes.

The hospital's nephrologist, however, said I am not allowed to take it pre-donation and advised against taking it after the surgery either. Does anyone have experience or knowledge of berberine and solitary kidney individuals?

I would prefer this not devolve into a discussion of keto or GLPs etc. Would like insight on berberine and it's effect on the kidneys.
