What research says

How it’s made and used

  • Children's daily intake3

    Scientists found that some children eating Green S may take in more than the recommended daily amount.

The signal at the top counts the findings in people and in animal and lab studies. A concern in studies of people outranks animal and lab studies, and “No concerns” needs at least one finding in people. When most findings in people point one way, the page leans that way (“Mostly”), and every finding is still shown. Findings whose study type is not stated are shown but not counted. This page is a reference, not medical advice. It describes what regulators and published research say. Talk to a doctor or dietitian about your own diet.

What expert reviews concluded

Expert panels that weigh all the research. Shown for context: the signal at the top does not count them.
