What is TESTED?
At SuppCo, we believe that supplement transparency shouldn't stop at the label. With the TESTED by SuppCo certification, consumers get independent verification that their products actually contain what the label claims — and brands get recognized for doing the right thing.
How does the TESTED program work?
Step 1
Brands Step Up To Get Tested
Brands that are confident in their manufacturing standards and unafraid to have their products secretly purchased and independently tested sign up for our certification program. SuppCo works with brand quality teams to ensure we test their products with validated laboratory methods.
Step 2
Independent Sampling
We anonymously purchase each product directly from the brand's website—just like you would. This ensures SuppCo's testing reflects the real inventory available to customers at a warehouse, instead of perfect samples picked from the production line that are traditionally used for certification.
Step 3
Accredited Testing
Samples are sent to ISO 17025 accredited laboratories, where key active ingredients in each product are tested for identity and potency against their label claims, so that consumers have confidence that what's in the bottle matches what's stated on the label.
Step 4
Multi-Layer Verification
If a test result is inconclusive, we repeat the process with two additional off-the-shelf samples. Only products that consistently meet or exceed 95% of their label claims earn the TESTED by SuppCo certification.
Step 5
Transparent Results
Every certified product's lab data is published on SuppCo's product page, including analyte-level details, so you can see exactly what was tested.
Step 6
Ongoing Integrity
All certified products are retested annually to ensure continued compliance. Products that fall short are guided through SuppCo's quality improvement process before reapplying for certification.
