Comparative metabolism of aspartame in experimental animals and humans.

Cross-Sectional Study

Human

1976 Nov

The study found that when your body breaks down aspartame, it turns into the same tiny parts found in eggs, meat, and fruits—and your body knows how to handle them without storing them up.

Narrative Review

Human

1989 Jan

This study checked what happens when people eat aspartame and found that it breaks down into three substances that our bodies already handle from food—and they don’t build up in us. So yes, it supports the claim.

Gold Standard Evidence Needed

According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.

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.
