Reb M
Reb M appears in 232 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
Reb M appears in 232 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.

What this page can and cannot answer
Use prevalence before concern
Only 18.1% of linked products carry any separately flagged ingredient. The stronger differentiator here is market placement: Reb M spans 60 named brands and is led by the Desserts group. Start with 20 g Protein Chocolate Fudge Flavored; 30g protein shake; 30g protein shake milk protein shake vanilla bean flavored when comparing real formulations. Because the flagged component may be something else, neither the low co-occurrence rate nor the 97.8/100 product average proves this ingredient safe.
60 named brands carry this ingredient
The processing evidence is heterogeneous rather than a single shelf pattern: the largest NOVA group contains 232 of 232 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.
What else is usually in the same product as Reb M
Across the 232 products on this site that list Reb M, these flagged additives appear alongside it most often. The comparison column is how often each one appears across every product with a parsed ingredient list, so the two figures are measured over the same set. Monk fruit extract shows up about 37x more often with Reb M than in the catalogue at large.
| Additive | Shared products | Share of Reb M products | Share of all products |
|---|---|---|---|
| Monk fruit extract | 43 | 18.5% | 0.5% |
| Sucralose | 27 | 11.6% | 2.7% |
| Caramel Coloring | 13 | 5.6% | 5.7% |
Co-occurrence describes what manufacturers formulate together. It is not a claim that these additives interact, and it carries no regulatory meaning. Counted over products with parsed ingredient lists; Open Food Facts, 2026-09-01.
