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. ## Frequently Bought Together - Best Naturals Vitamin B2 (Riboflavin) 400mg - Migraine Relief - Veggie Capsules - Conezyme Precursor - 120 Count - Magnesium 400mg [High Potency] Supplement – Magnesium Oxide for Immune Support, Muscle Recovery, Leg Cramps and Relaxation 120 Tablets --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/160216076-best-naturals-vitamin-b2-riboflavin-400mg-veggie-capsules-conezyme-precursor](https://www.desertcart.jp/products/160216076-best-naturals-vitamin-b2-riboflavin-400mg-veggie-capsules-conezyme-precursor) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-11*
