- No. Aspartame contains phenylalanine, and products containing it must carry a warning — this is the only absolute contraindication.
- Is E951 dangerous?
- On the classification this reference uses, E951 is "debated". Intense sweetener; contraindicated for phenylketonuria (contains phenylalanine). That is a summary of the Russian TR CU 029/2012 list and the EU permitted lists, not medical advice.
- How do I check whether E951 is in a product I have?
- Photograph the barcode or the ingredients panel — the app reads the list and flags every additive it finds. Three checks are free, with no account.
