I dropped a "zero" tablet into my water bottle today (I got it with a wiggle order; would have preferred Haribo). Two questions Who would think that orange-cherry is a good flavour??? (more seriously) why replace sugar with sucralose? Your body knows the difference sugar/glucose and artificial sweeteners "Studies using this method have reported that simply having carbohydrate in the mouth is associated with improvements in endurance performance. " http://www.ncbi.nlm.nih.gov/pubmed/21615187 If you are doing a workout long enough to need to replace electrolytes, surely you are going to need a little carbohydrate before the day is done, and that will apparently immediately improve performance, so why introduce something that is "is manufactured by the selective chlorination of sucrose" (thanks wikipedia) into the mix?
