The quality promise behind every batch
The unglamorous rules that decide whether a supplement deserves your trust, and how Neurozen meets each one.
Made in the USA, under cGMP rules
Neurozen is bottled in an FDA-registered facility in the United States operating under current Good Manufacturing Practices, the federal quality framework covering everything from ingredient quarantine to equipment cleaning logs. Registration does not mean FDA endorsement, and we will never claim it does; it means the facility is inspectable and runs to a documented standard.
Evan spent fourteen years inside contract manufacturing before co-founding the brand, which is precisely why we pay for the boring parts: supplier qualification, incoming raw-material identity checks, and small production runs that never sit long enough to go stale.
What every batch is tested for
Identity
Each botanical and amino acid is verified to be the ingredient the label names, not a lookalike species or a cheaper substitute.
Potency
The finished liquid is checked against the blend specification, so dropper one and dropper sixty deliver the same formula.
Heavy metals
Screened against limits for lead, arsenic, cadmium, and mercury, the contaminants botanicals are most likely to carry.
Microbial purity
Tested for yeast, mold, and bacterial contamination, with the liquid base formulated for shelf stability.
Testing is performed independently of the production line on every batch, before release. We do not publish lab paperwork on this site; what we publish is the promise, and the 60-day refund that makes it enforceable by you.
Plain-English translations
Stimulant-free means no caffeine, no synephrine, nothing that races. Vegetarian means no gelatin and no animal-derived actives. Dairy-free and gluten-free mean the formula contains neither, useful if your mornings involve sensitivities. Made in the USA refers to the bottling and testing; like nearly every supplement brand, some raw botanicals are grown where they grow best and qualified on arrival.
Sold direct only is a quality claim too: one warehouse, climate-controlled, first-in-first-out stock rotation, no marketplace middlemen aging inventory in a hot trailer. It is the least photogenic part of quality and probably the most important.
Keeping the drops at their best
Keep the bottle capped, upright, and out of direct sun; room temperature is fine, and refrigeration is optional. The amber glass is not decoration, it is UV protection. Use within the period printed on your bottle, and give it a gentle swirl before the first dropper of a new bottle.
Quality you can test from your kitchen
Sixty days, your ears, our promise. That is the real audit.
