Is AG1 Third-Party Tested? Yes, Here’s How and Why
With certifications from Informed Sport and Cologne List® and third-party testing in ISO-certified labs, AG1 goes far beyond what’s legally required to ensure every scoop is clean, consistent, and safe.
Most supplements never go through third-party testing – because they don’t have to. AG1 chooses to do it anyway.
Why Third-Party Testing Matters
When it comes to quality assessment, supplements are treated like ordinary foods. That means they’re only required to meet basic safety and labelling laws – not to prove purity, potency, or absence of contaminants. Most supplement brands stop at the legal minimum. They’re not required to conduct independent purity testing or continuously re-test their batches – and many don’t.
AG1 does. We test every batch through third-party labs to verify that each scoop is controlled for heavy metals, microbes, and banned substances. Our limits are stricter than those required by law – it’s the standard we want to set for the industry.
We go even further by partnering with organisations like Informed Sport and Cologne List. It’s an investment most companies skip – but one that gives you the peace of mind you deserve.

What Is Third-Party Testing Exactly?
Third-party testing means laboratories unaffiliated with the brand analyse samples of raw materials, in-process formulations, or finished products to verify:
- Purity (e.g. absence of heavy metals, microbial contaminants, residual solvents)
- Potency and label accuracy (i.e. confirming that nutrient amounts match the label)
- Absence of undeclared or harmful substances (including known doping / banned compounds)
- Consistency across batches
To be credible, such labs work under recognised accreditations and follow validated methods. All of AG1’s third-party testing is done in ISO/IEC 17025-accredited labs.
And What Are Third-Party Certifications?
A third-party certification – like Informed Sport or Cologne List® – is an added layer of certainty and peace of mind. While third-party testing evaluates AG1’s quality at the lab level, third-party certifications are programs that formally review, test, and confirm that a product and its manufacturing processes meet strict safety and quality standards.
These certifications are completely voluntary – AG1 chooses to pursue them because they reflect our commitment to transparency and athlete-level quality assurance.
In short: third-party testing evaluates our quality, and certifications like Informed Sport and Cologne List® underline it.
