I, personally, have actually been having pretty good results with berberine (yes, yes, I know its a TikTok trend right now). Its really helped control my hunger and I haven't noticed any side effects.
I've considered trying berberine just for the heck of it, but it seems like it reduces the diversity of the gut bacteria which makes me concerned that if it didn't work out well for me it wouldn't be a simple as stopping taking it.
