In U
In U appears in 1 indexed US food products. No FDA SAFFA status or CSPI rating is attached in this snapshot, so this page reports prevalence rather than a safety verdict.
What the data can answer
In U appears in 1 catalogued products, but this snapshot has no FDA SAFFA status or CSPI Chemical Cuisine rating attached to it. This page therefore cannot answer whether the ingredient is safe from those sources. It can show how often it occurs, where it tends to sit on labels, and which kinds of products contain it.

Catalog prevalence comes from Open Food Facts ingredient lists. FDA SAFFA and CSPI Chemical Cuisine labels are shown only when the source record contains them.
How to use this page
Audit the co-occurring flags first
100% of the linked products contain at least one separately flagged ingredient, making co-occurrence the dominant follow-up question. That figure does not identify In U as the trigger. Open records such as Worcestershire Sauce and inspect which ingredient row carries the caution marker. The 60.0/100 product average is therefore a triage signal for this surrounding formulation set, not an ingredient verdict. Its 93% average label depth helps locate the term when checking the package.
100% of linked products contain a separately flagged ingredient
Processing is unusually concentrated here: Group 4 accounts for 1 of 1 NOVA-tagged records. That describes the surrounding products, not the substance. For a useful comparison, hold category and processing level constant, then inspect which named component changes alongside the caution flag; otherwise the product mix will confound the ingredient question.
Next check: open the lowest-scoring linked formulation and locate the exact caution-marked component.

In U — common follow-ups
How should I read safety signals when In U sits in heavily flagged products? ▼
100% of linked products contain at least one separately flagged ingredient, so the first task is locating which row carries the caution marker — not assuming In U is the trigger. None of that replaces a product-, dose-, allergy-, or person-specific determination.
Where does In U show up across the catalog? ▼
In U sits above the median for catalog prevalence (1 products, #71,300 of 247,206) across 1 named brands. Category mix varies — use the linked records rather than treating any single shelf as representative.
Why is In U so common on ingredient lists? ▼
The current source record does not specify a technical effect for In U. Its near the end of the captured list and product examples are shown without guessing why manufacturers include it.
