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: As 5-mthf reaches 3 named brands, most often appears under Dietary supplements, and typically sits in the upper half of the list. Product examples include AG1 Daily Foundational Nutrition; AG1 Tropical; Daily Foundational Nutrition. 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?
