Frequently asked questions
- Is E300 vitamin C?
- Yes, literally. A good example that the E-number is a registry index, not an indicator of harm.
- Is E300 dangerous?
- On the classification this reference uses, E300 is "safe". Antioxidant, vitamin C. 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 E300 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.
Check a product rather than guess. Photograph the barcode and the app reads the ingredients, decodes every code and marks the ones worth knowing about.
