Reading this ingredient record
A clean co-occurrence count is not a safety clearance
No linked product currently contains a separately flagged ingredient, but zero co-occurrence is an absence-of-evidence result, not regulatory approval. The practical reading is about use: Magnesia reaches 2 named brands, most often appears under Snacks, and typically sits near the end of the captured list. Product examples include Judi Cakes, Cream Cheese Poundcake; Judi Cakes, Cream Cheese Poundcake, Caramel Sea Salt; Judicakes, Cream Cheese Poundcake. Check the current label and authoritative source databases when the decision involves allergies, dosage, pregnancy, or a medical condition.
0% of linked products currently carry a separately flagged ingredient
Most NOVA-tagged examples land in Group 4 (4 of 4), yet the products span unrelated categories. That contrast matters: processing class can describe how a food was made while saying nothing decisive about this ingredient's regulatory status. Use the linked examples to understand formulation context, and leave the unanswered toxicology or individual-sensitivity question unanswered.
Next check: verify the unresolved source rating directly instead of converting zero co-flags into reassurance.
How do the sampled products compare?
Each point is one of the 4 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.
