I've tried so many, but xylitol seems to be my ultimate fav, for the taste it's the best and it doesn'tleave after taste, as well it's 100% natural and it's good for your teeth, as it fights tooth decay and stabilises insulin and hormone levels and promotes good health. But overly consumed it has laxative effect, and has 4 garbs per tea spoon, although you can half the amount to what you normally use. So if you normally have one tea spoon of sugar in your tea/coffe, with xylitol you need only half the amount. And if you limit the cup only once in a morning, then it's ok. anyhow that's what I do.
