Isoleucine
Isoleucine appears in 43 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
Isoleucine appears in 43 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.
Isoleucine sits in the busiest tenth of the catalog (#5,507 / 247,206)
- Usage rank

- of 247,206 ingredients that appear in at least one catalogued product, tied with 95 others that also appear in exactly 43 products.
- Typical depth in an ingredient list
- 43%
- Of the way down the captured list, averaged across the 43 products listing it (mean slot 12.1). Isoleucine usually falls in the upper half of the 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.
Reading this ingredient record
Use prevalence before concern
Only 16.3% of linked products carry any separately flagged ingredient. The stronger differentiator here is market placement: Isoleucine spans 26 named brands and is led by the Dietary supplements group. Start with Aquarius, soft drink; Arizona, energy drink, mucho mango; Arizona, natural energy drink, watermelon when comparing real formulations. Because the flagged component may be something else, neither the low co-occurrence rate nor the 97.1/100 product average proves this ingredient safe.
26 named brands carry this ingredient
The processing evidence is heterogeneous rather than a single shelf pattern: the largest NOVA group contains 43 of 43 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 Isoleucine
Across the 43 products on this site that list Isoleucine, 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. Sucralose shows up about 6x more often with Isoleucine than in the catalogue at large.
| Additive | Shared products | Share of Isoleucine products | Share of all products |
|---|---|---|---|
| Sucralose | 7 | 16.3% | 2.7% |
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.
