When the researchers conducted spatial learning and memory tests using the Barnes maze, the aspartame mice at four months consistently moved more slowly and covered less distance during training than animals in the control group. They also took nearly twice as long on average to locate the target escape hole, showing impaired memory recall (however, this was inconsistent and not seen as statistically meaningful). By eight months, performance gaps widened even further, with two out of six aspartame-treated mice failing to complete the task at all.
It makes you dumb, unfit and fat (around the organs).
Also you will usually find 950 (aspartame) along with 951 (acesulfame K) because the two have slightly different profiles and work very well together. If we do a study on humans I would want it to include the common and also some uncommon combinations. A lot of people are switching over to erythritol and stevia but I don’t know how safe they are. We make erythritol internally but the dose may be quite different, and coming in through the gut could be quite different to internal production, not to mention with the stevia as actually prepared not lab purified.
Erythritol in particular actually had a study recently that was also concerning
