Selenomethionine
Selenomethionine appears in 13 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
Selenomethionine appears in 13 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.

- Of the way down the captured list, averaged across the 13 products listing it (mean slot 30.1). Selenomethionine usually falls near the end of the captured list; this position does not measure its amount because source formatting, compound ingredients and labeling exceptions vary.
Computed from parsed product ingredient lists (Open Food Facts). The ranking covers 247,206 ingredients that appear at least once. Neither usage rank nor label depth is a safety clearance.
How to use this page
Use prevalence before concern
Only 7.7% of linked products carry any separately flagged ingredient. The stronger differentiator here is market placement: Selenomethionine spans 6 named brands and is led by the Beverages group. Start with Complete Protein Shake Creamy Vanilla Bean; Hair, Skin & Nails Gummies; Kid Drinx, Super Punch Powdered Drink Mix, Cherry when comparing real formulations. Because the flagged component may be something else, neither the low co-occurrence rate nor the 98.8/100 product average proves this ingredient safe.
6 named brands carry this ingredient
The processing evidence is heterogeneous rather than a single shelf pattern: the largest NOVA group contains 13 of 13 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 13 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.
