sugar replacement

[Huh]

Hello everyone!!
new to forum and not even sure i am posting this in the correct part of the forum...
I like the to use xylitol for sugar replacement however, from what i understand you only want to really only use xylitol from birch trees which is not most of the time the case...its actually made from corn...and we know all about gmo corn... i have also read that xylitol coming from china is also questionable bcuz it is made from corn...soooooo  have you found a true birch xylitol??
