What We Couldn't Verify
- Large multinational (EUR 6B+ total revenue). Health & Nutrition is one division within Glanbia Nutritionals (split from Dairy Nutrition, January 2025)
- Glanbia Performance Nutrition (Optimum Nutrition, BSN) is a separate consumer brand division and does NOT sell ingredients to supplement manufacturers
- A 2022 FDA warning letter was formally retracted by FDA after Glanbia proved the cited products were not theirs (fraudulent website, not a Glanbia quality issue)
- Certification details beyond cGMP not independently verified from public databases
- On-site facility inspection was not conducted
