Published research: what individual studies found
These are findings from individual published studies and food-safety agency opinions, credited to each paper. Each one is labeled by type of evidence. They do not change any verdict, evidence grade or score on this site.
Evidence type: EFSA re-evaluation (2010)
- EFSA (2010) estimated that, at current use levels (Tier 3), intake of lutein (E 161b) by the highest consumers may exceed the ADI (1 mg/kg bw/day) at the upper end of the range. The ADI applies to a specific Tagetes-derived lutein.
- About the ADI: An ADI is a safety benchmark with a built-in margin. An estimate above it is not a measured intake and doesn't mean harm has occurred.
