Query: I trust now foods to do xylitol right

. I once worried about something so sweetactually having some sugar in it;but if Now Foods is doing this right,then there are great reasons to soak teeth in xylitol:not only does it kill germs,it feeds enamel at the same time .. it's also a form of energy for bonesbut eating more than 50g is hard on the liver .
