Xylitol is a non-artificial sweetener derived from plants. Although I have used XyloSweet in drinks in the past, my consumption is usually confined to chewing it in sugar-free gum.
Xylitol is actually good for your dental health. This natural sweetener has about 75% fewer carbs (and fewer calories) than sugar, and does not raise my blood sugar. There are other claimed medical and nutritional benefits to using xylitol, and you can read about them on this xylitol website.
