What the data can answer

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.

How to use this page
Use prevalence before concern
Only 14.3% of linked products carry any separately flagged ingredient. The stronger differentiator here is market placement: L-cysteine Hcl spans 4 named brands and is led by the Undefined group. Start with Bashas', Burrito Size Flour Tortillas; Bashas', Flour Tortillas; Ener-c when comparing real formulations. Because the flagged component may be something else, neither the low co-occurrence rate nor the 93.6/100 product average proves this ingredient safe.
4 named brands carry this ingredient
The processing evidence is heterogeneous rather than a single shelf pattern: the largest NOVA group contains 7 of 7 classified products, leaving a meaningful remainder elsewhere. This breadth is why the page reports label depth, category, and product examples separately. Those dimensions help locate comparable products; combining them into a stronger safety claim would hide the variation the catalog actually contains.
Next check: compare label position across two brands before treating prevalence as equivalent exposure.
How do the sampled products compare?
Each point is one of the 7 sampled products listed below: its overall safety score against how many separately flagged ingredients its label carries. Bubble size is the number of ingredient rows the label actually resolved to.
