Common questions
Is Irwin Naturals third-party tested?
1 of 126 Irwin Naturals products are third-party tested. The rest show none on the label, and no testing lab's list we read names them.
Does no seal mean a product failed a test?
No. It means the label shows no third-party test, and no testing lab's list we read (BSCG, IFOS, IGEN, IKOS, Informed Choice, Informed Sport) names the product. A brand can test privately. This page shows what the label and the lists show.
Where does the label data come from?
The NIH Dietary Supplement Label Database, which is public domain. We read the file dated 11 January 2026. Brands change labels, so check the one you have.
Our method
- Third-party tested
- A seal from an outside lab that tests what is inside, printed on the label, or the product's name on that lab's own list.
- Additives
- Each other ingredient on the label, checked for artificial coloring, titanium dioxide, hydrogenated oil and BHA/BHT preservative, after a physician spoke against dyes, fillers and preservatives on video.
“…that are at the right Doses and that are effective and that don't have a lot of additives and fillers and preservatives and chemicals and dyes”
- Form
- The form printed on the label. When an expert we quote has talked about that form, the speech bubble next to it says where they stand. Open it to see what they said.
- One product, many labels
- Label versions that share a UPC count as one product. The newest label is the one shown.
- Dose
- The amount is shown as printed. Whether it suits you depends on your blood test.
