How to use this page
Use prevalence before concern
Only 10.5% of linked products carry any separately flagged ingredient. The stronger differentiator here is market placement: Dl-methionine spans 9 named brands and is led by the Dog-food group. Start with AKA MISO SOUP Soybean Paste Soup (red); Beef Meal & Rice Recipe; Cage-Free Chicken Brown Rice & Sweet Potato Recipe when comparing real formulations. Because the flagged component may be something else, neither the low co-occurrence rate nor the 97.6/100 product average proves this ingredient safe.
9 named brands carry this ingredient
The processing evidence is heterogeneous rather than a single shelf pattern: the largest NOVA group contains 17 of 18 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.
