I have yet to encounter a soda that uses sugar alcohols, most use aspartame, ace-K, sucralose, or stevia. Those don't bother me at all.

But the side-effects of sugar alcohols are pretty well known (especially to anyone who has had the pleasure of eating beyond their threshold). I haven't searched for any papers but I'm sure you'll find plenty that conclude that many people have adverse reactions to sugar alcohols.

It's in sugar free red bull unfortunately.

Not where I live (ace-K and sucralose). Maybe it differs per region.
