Aspartame is, because of all the claims against it, the single most studied food substance known, and it seems to somehow keep coming okay. There are a lot of studies with really bad methods that were a smear job attempt but science doing what it does they were labeled for what they are and disregarded. Is it possible to be allergic and a reaction to be anxiety sure, but that is not on the food.
