N-acetyl-l-tyrosine
N-acetyl-l-tyrosine appears in 23 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
N-acetyl-l-tyrosine appears in 23 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.
What this page can and cannot answer
Audit the co-occurring flags first
82.6% of the linked products contain at least one separately flagged ingredient, making co-occurrence the dominant follow-up question. That figure does not identify N-acetyl-l-tyrosine as the trigger. Open records such as Berry Burst Energy Drink; Berry Melon Fizz; C4 Frozen Bombsicle and inspect which ingredient row carries the caution marker. The 76.5/100 product average is therefore a triage signal for this surrounding formulation set, not an ingredient verdict. Its 48% average label depth helps locate the term when checking the package.
82.6% of linked products contain a separately flagged ingredient
Processing is unusually concentrated here: Group 4 accounts for 22 of 22 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.

How do the sampled products compare?
Each point is one of the 16 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.

N-acetyl-l-tyrosine — common follow-ups
How should I read safety signals when N-acetyl-l-tyrosine sits in heavily flagged products? ▼
82.6% of linked products contain at least one separately flagged ingredient, so the first task is locating which row carries the caution marker — not assuming N-acetyl-l-tyrosine is the trigger. None of that replaces a product-, dose-, allergy-, or person-specific determination.
Which product shelves show up most often with N-acetyl-l-tyrosine? ▼
