The Claim
Aspartame metabolism produces aspartic acid, phenylalanine, and methanol, which in experimental models may contribute to excitotoxicity, neurotransmitter imbalance, and oxidative stress, thereby implicating these pathways in neurovascular unit disruption.
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.
When your body breaks down aspartame (an artificial sweetener), it makes three substances that, in lab studies, might mess with brain cell signaling and cause stress — potentially harming the tiny blood vessels and nerves in the brain.
See the scientific wording
Aspartame metabolism generates aspartic acid, phenylalanine, and methanol, which in experimental models may contribute to excitotoxicity, neurotransmitter imbalance, and oxidative stress — pathways implicated in neurovascular unit disruption.
What the research says
1 studyThis study says that aspartame, the artificial sweetener, might harm the brain by triggering harmful chemical reactions, even at normal intake levels — which matches what the claim says.
