← Quality & Compliance Overview

Supplement Quality Control Laboratory

Every batch tested, every product verified.

Four documented checkpoints between the incoming goods bay and the sealed carton — with a laboratory result behind every one.

Quality in supplement manufacturing is not a final inspection — it is a sequence of controls, each one narrow enough to catch a specific class of failure. Ours runs from the incoming goods bay to the sealed carton, with a documented result behind every checkpoint.

Where Every Batch Is Proven, Not Assumed.

THE LABORATORY

Our analytical laboratory runs identity, assay, microbiology and physical testing on incoming materials and finished product. Instruments are calibrated on a fixed schedule and results are recorded against the batch.

Inside the analytical laboratory

Testing is performed in-house by our own QC team, so a batch is never waiting on an outside queue to be released. Below are the four capability areas a released batch passes through.

Analytical laboratory for supplement quality control

Analytical & wet chemistry

Identity confirmation, assay, pH, moisture and loss-on-drying run in a dedicated analytical room, with a documented result filed per lot.

Precision analytical instrument used for supplement assay testing

Instrumented assay

Precision instrumentation is calibrated on schedule and used for content uniformity and potency checks against the locked specification.

Physical & release testing

Fill weight, shell or tablet weight, hardness, disintegration and seal integrity are verified before a batch is signed off for release.

Pipetting sample preparation for stability testing in the laboratory

Sample & stability preparation

Pilot and pre-shipment samples are prepared and held under controlled conditions, so a customer-directed retest has retained material to work from.

The four checkpoints

01

Incoming raw materials

Every lot is checked against specification before it enters production: identity, appearance, assay where applicable, and supplier documentation. Material that does not match is not released to the line.

02

In-process control

Blend uniformity, fill weight, shell or tablet weight, hardness, moisture and seal integrity are monitored during the run. Deviations are corrected on the line rather than discovered in the finished batch.

03

Finished product

Released batches are tested against the locked specification. Results are issued as a Certificate of Analysis that accompanies the shipment, so your own buyer or regulator can review the data independently.

04

Documentation

Every checkpoint leaves a record. The document set below travels with the shipment, not behind it.

DocumentWhat it covers
Certificate of Analysis (COA)Finished batch results against specification
Material Safety Data Sheet (MSDS)Safe handling information
Specification sheetFull ingredient list as used in the batch
Nutritional panelNutrient values per serving
Allergen statementDeclared allergens and cross-contact controls
Certificate of originCountry of manufacture
Health certificateIssued for markets that require it

Independent testing

Customer-directed third-party testing is welcome. We can submit pre-shipment samples to a laboratory of your choosing, or arrange in-house testing and forward the report with the shipment.

See the certifications page for the facility certificates these systems operate under, or the capabilities page for the laboratories and equipment themselves.
