Evidence summary
What the One data means.
One has 1 product record in the current NonToxic.com database, spanning 1 category: Baby Products. The average score of 72/100 uses only 1 rated records. Shoppers should inspect product-level records because packaging, processing, test year, and contaminant fields can vary inside the same brand.
The current evidence mix for One is 1 medium confidence. Source labels represented on this page include PlasticList (plasticlist.org) (1), and test-year labels include 2024 (1). 0 records lack a verified product-specific testing source and 0 records lack a verified test year. These items should drive source review and brand transparency requests before any broad safety claim is made.
Verified testing sources: Source record 1.
For practical review, start with One A Day Womens Prenatal 1 Multivitamin with DHA & Folic Acid, then use the category page to compare competing products because this brand set does not yet contain a separate stronger-scoring item. Use the linked category page to compare competing brands, packaging formats, source confidence, and newer test years before treating the brand record as complete.
How to use this brand page.
Use this page to decide what to inspect next, not to label every One product safe or unsafe. A brand with one listed product has a narrow evidence base, while a brand with many products may mix lower-concern records with elevated or highest-concern records. The most defensible workflow is to open the product page, read the source row, compare the category alternatives, and submit a correction if a newer lab report or packaging disclosure changes the evidence.
