What research says

How it’s made and used

  • Urine levels after eating1

    People who ate pancakes made with sodium aluminium phosphate had more aluminium in their urine afterwards.

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 two findings in people. Findings whose study type is not stated are shown but not counted.
