## Questions & Answers

**Q: Where is the sign for 3rd party tested?**
A: I buy Best Naturals Vitamin B-2 400 mg "Premium Formula". 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.
