Quality

How NEXRY tests every batch.

We treat every batch the way a pharmaceutical company would — independent labs verify what's on the label is what's in the tub, and that nothing else made it in.

What we test

Identity — every active is identified at the molecular level (HPLC / mass spectrometry where applicable)
Potency — every active is quantified to confirm label-stated dose
Heavy metals — lead, arsenic, cadmium, mercury (USP <232>)
Microbial — total plate count, yeast, mould, E. coli, Salmonella
Allergens — gluten, dairy, soy as relevant to the formula

Who tests our products

We partner with ISO 17025-accredited third-party laboratories independent of our manufacturers. We rotate testing partners annually to avoid single-lab bias. Current partners are listed on each product's Certificate of Analysis.

How to access COAs

Every batch has a Certificate of Analysis available on request. Email coa@getnexry.com with the batch number printed on your tub, and we'll send the PDF within one business day. We're rolling out a public batch-lookup tool — see Certificates of Analysis.

Manufacturing standards

NEXRY products are manufactured in GMP-certified facilities under applicable regional Good Manufacturing Practice standards for food-grade supplements.
