Tks, all welcome information. Any comments on some of the side effects of Metformin & vitamin depletion particularly B12s?
Well, I know of some OTC herbal equivalents to Metaformin for hepatic gluconeogenesis.
One such is Jiaogulan (Gynostemma Pentaphyllum), which some say is as good, or better.
Another is Berberine, again in comparison with Metaformin.
Another is Rutin. The first two herbs have several good scientific analysis online. Less so for Rutin, but there are some.
As far as directly lowering blood sugar, Gymnema (G. Sylestre) (aka “The Sugar Killer”) is the champ. (Also popular, so inexpensive.)
