You can look up each product's notification by the number on the package in the Consumer Affairs Agency's database (Japanese).

In the EU: the register of health claims

EU-authorised claim

  • The claim "Chicory inulin contributes to normal bowel function by increasing stool frequency" is authorised (condition: 12 g per day).
  • Claims such as "increases bacteria in the gut" and "satiety" were not authorised.

In the EU, only health claims whose evidence has been assessed by the European Food Safety Authority (EFSA) and authorised by the European Commission may be used on food. “Not authorised” means the evidence for that claim was not established under EU standards — not that the ingredient is dangerous.
