The bottle clearly indicates "3rd Party Lab Tested". The bottle pictured does not state "Premium Formula"; it's labeled "Coenzyme Precursor" and does not say anything about it being tested by a third party. **Q: Are these vegan? (guaranteed free of all animal products)** A: According to ingredients listed , its all VEGAN. **Q: Is this usp verified?** A: I was unable to find a USP Certification on the bottle. It is a "Good Manufacturing Practice Product" and made in the USA. Don't know if that helps. I checked my bottle of Centrum Multivitamins and it doesn't show a USP Certification either. **Q: What is the source of the B-2 itself? I understand that the capsule and fillers are vegan, but I don't see a source for the B-2.** A: I use it for headaches. My doctor recommended it for patients with migraines. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worth trying. *by N***N on 6 February 2026* Bought to help reduce migraines.
