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 Aspartame as the trigger. Open records such as 12 Fl Oz; 3 Hour Mint, Peppermint; 3 in 1 Milk Tea Powder and inspect which ingredient row carries the caution marker. The 51.2/100 product average is therefore a triage signal for this surrounding formulation set, not an ingredient verdict. Its 51% average label depth helps locate the term when checking the package.

Processing is unusually concentrated here: Group 4 accounts for 3611 of 3611 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.

What else is usually in the same product as Aspartame

Across the 3,611 products on this site that list Aspartame, 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. Acesulfame Potassium shows up about 37.6x more often with Aspartame than in the catalogue at large.
