The Claim
Phenylalanine derived from aspartame is primarily incorporated into body proteins in humans and animals either in its unchanged form or after conversion to its metabolite tyrosine.
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 something with aspartame (a sugar substitute), your body uses the phenylalanine in it to build proteins, either as-is or after turning it into another substance called tyrosine.
See the scientific wording
Phenylalanine from aspartame is primarily incorporated into body protein either unchanged or as its metabolite tyrosine in humans and animals.
What the research says
1 studyStudy: Comparative metabolism of aspartame in experimental animals and humans.
The study found that when people and animals eat aspartame, the phenylalanine in it gets used to build body proteins either as-is or after turning into tyrosine — just like the claim says.
