The Claim
Aspartame is hydrolyzed in humans and multiple animal species to release methanol, which is subsequently oxidized to carbon dioxide via the one-carbon metabolic pool, and the resulting dipeptide is cleaved by intestinal dipeptidases to release free aspartic acid and phenylalanine, which are then absorbed.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When you eat or drink something with aspartame, your body breaks it down into smaller pieces, including methanol (which turns into carbon dioxide), and two amino acids—aspatic acid and phenylalanine—that your body absorbs.

What the research says
1 studyStudy: Comparative metabolism of aspartame in experimental animals and humans.
The study showed that when people and animals eat aspartame, their bodies break it down exactly as the claim says — into methanol, aspartic acid, and phenylalanine, which are then used or expelled in predictable ways.
