The Claim
Available clinical studies suggest that aspartame has no harmful metabolic effects in humans, although the evidence supporting this conclusion is limited and based on observational data.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Some studies say eating aspartame doesn’t mess up your metabolism, but the studies aren’t very strong or many — they just watched people instead of testing them in controlled experiments.

What the research says
1 studyStudy: Aspartame Metabolism in Normal Adults, Phenylketonuric Heterozygotes, and Diabetic Subjects
This study checked what happens in people’s bodies after they consume aspartame and found no harmful changes in blood chemicals, so it supports the idea that aspartame is safe — but it also admits we don’t have a lot of data, which matches the claim.
