Testing & Quality

Our Commitment to Proven Purity

Quality is not assumed. It is verified.

Every ingredient, and every batch, moves through identity verification, safety screening, and documentation control undertaken by our own team before it reaches you.

Supplier Certificates of Analysis are reviewed as part of the record, but we do not rely on that documentation alone. Additional independent analytical verification confirms identity, purity, and regulatory compliance prior to release.

Each result is batch-linked, retained, and available for transparency. At REIN, verification is traceable and published, not simply declared.

FTIR Identity Testing (Raw Materials):

Every incoming raw material is tested using FTIR spectroscopy to confirm that it matches its Certificate of Analysis (COA). This ensures the ingredient is exactly what it claims to be before production begins.

Heavy Metal Screening:

All REIN Nutrition™ products are independently tested for heavy metals including lead, mercury, cadmium and arsenic, in accordance with recognised food safety contaminant limits.

Whey Protein Verification:

In addition to the tests above, REIN Nutrition™ Whey Protein is independently tested to confirm declared protein levels and ensure accuracy on every batch.

Published Results:

REIN publishes batch-linked analytical results for each product so you know exactly what you are consuming every time. In a market where finished-product verification is not always required prior to sale, REIN verifies before release, not reactively after a problem arises. Transparency is built into our process from the start.

Our Testing Standards

We believe that trust is built through testing, not advertising. REIN invests in independent verification with heavy-metal screening so that purity is proven, not promised.

Product	Tests Conducted	Purpose

Why It Matters

Research and regulatory reviews show that a significant portion of the global supplements market contain mislabeling and undeclared or contaminated ingredients.
REIN exists to eliminate that risk. We test raw materials before production begins. We independently validate finished products before they are released. Every batch is traceable.

Transparency You Can Trust

All REIN Nutrition™ testing is conducted by independent ISO 17025-accredited laboratories.
We publish key testing summaries and maintain COA and batch verification records for full transparency.
