Where it is made

Quietum Plus is manufactured in the United States in a facility that is registered with the FDA and operates under current Good Manufacturing Practices (cGMP). These standards govern cleanliness, equipment, staff training, and record-keeping at every step, from raw-material intake to final sealing.

Independent laboratory testing

We do not grade our own homework. Each production run is tested by Sennen Botanical Testing, LLC, an independent laboratory working to ISO/IEC 17025 standards. The current batch results are published on the verification page so you can review them yourself.

What we test on every lot

Botanical identity

Confirms each plant extract is what the label says, using validated identity testing.

Potency

Verifies active compounds meet the labeled amounts via HPLC-DAD.

Heavy metals

Screens for lead, arsenic, cadmium, and mercury by ICP-MS, with a threshold of < 0.8 ppm.

Microbial limits

Tests for total counts and pathogens to confirm results stay within USP limits.

Allergens and GMO

Confirms non-GMO status and screens for common allergen cross-contact.

Quality is the process, verification is the proof

Think of this page as the method and the verification page as the result for the lot you receive. Together they are how we turn quality from a promise into something you can confirm. For the company behind the standards, see our story.
