Thanks Andbreathe
Yes, I tried Berberine for a while. So has
@Oldvatr I believe?
My experience went nowhere, because I failed miserably to take the tablets consistently enough to see any benefits. So I can't comment from a personal perspective.
However, I would caution you from adding Berberine to an existing Metformin regime.
You can check out any possible contraindications online, since there is a risk that they will interact with each other.
But both drugs act in fairly similar ways, and may cause similar digestive upsets - so doubling up on those may not be a good idea. And there is the additional factor that Metformin has a maximum beneficial dose. This means that once that beneficial dose is exceeded, the benefits do not increase in line with further increasing the dose. I suspect that Berberine may be similar.
So basically, I wouldn't take both drugs together without doing a great deal of research, and with the knowledge and consentof your health team...
Hope that helps.
