Can you please show us a picture or point us to a website that has a picture of the ingredients list for propel zero or propel fitness that includes aspartame? I drink it all the time and I even just now looked again, and Aspartame is certainly NOT listed. the only listing is Sucralose (splenda). there is however studies being done regarding splenda, the Italians are at this time doing studies because they think it may be linked to leukemia. I also know that my cousin had kidney disfunction after using splenda daily for several years, and had to stop using it.
