Since I recently had this discussion, I just copied this verbatim from an old email of mine:

Speaking of kidneys, I tried to google sorbitol-free hydration tables and found a post on RW's forum from an internal med doc responding to someone complaining about GI issues with Nuun. He stated that Nuun contains 3 laxatives: magnesium sulfate (epsom salts), sorbitol, and polyethylene glycol (Merilax). He also said he was surprised that most people don't have GI issues from it.

I cannot tolerate sorbitol so the only tablet I have tried is Nathan. When I only have an hydration bladder to carry liquid, I use Elete drops and a Nathan tablet for flavoring. Elete seems to have the best balance for both me and my hubby. When I have a water bottle and need to be taking in calories also, I'll use Cytomax and bump up the electrolytes with Elete.
