Quality, testing and sourcing
Neuroxen is manufactured in the United States in an FDA-registered facility that follows current Good Manufacturing Practices (cGMP). Quality is not a slogan here; it is a documented process that ends with the verification table you can read on the verification page.
Where it is made
Production runs in a cGMP facility with controlled temperature, humidity, and air handling. Every production step, from raw-material intake to capsule filling and bottling, is logged so that any finished bottle can be traced back to its lot.
What we test on every lot
- Identity of each botanical by HPLC fingerprinting
- Potency of standardized actives against label claim
- Heavy metals by ICP-MS, with a release limit of < 0.35 ppm
- Microbial safety to USP standards (Within USP limits)
- Screening for common allergens and contaminants
The independent laboratory
Final testing is performed by Stillwater Verification Labs, LLC, an ISO/IEC 17025 accredited third-party laboratory independent of our manufacturing. The current lot, LOT-NXN-260512, was released at 99.0% via UHPLC active purity. Their certificate is filed under SVL-2026-COA-0884 and referenced on the verification page.
Sourcing and suitability
We use standardized botanical extracts, algal (not fish) DHA, sunflower-derived phosphatidylserine, and chelated minerals. Neuroxen is non-GMO and free of soy, dairy, and gluten. Raw materials arrive with supplier documentation that is checked before anything enters production.
Stability and storage
Finished bottles are sealed under tamper-evident caps and stability-tested to confirm the actives hold their labeled potency through the printed best-by date. Store Neuroxen in a cool, dry place out of direct sunlight, and keep the cap closed. Because every bottle is tied to a documented lot, a sealed, in-date bottle bought through this portal carries the full traceability described on the verification page.
