Our Values

We believe consumers should be able to trust what’s on a supplement label. That’s why we independently test products and give responsible brands a clear way to prove that what they sell is what they say it is. Our accreditation mark gives consumers an independent signal of trust, while helping brands demonstrate their commitment to quality, accuracy and transparency.

Innovation

We’ve mapped a global network of 150+ accredited laboratories, giving us access to an exceptional range of supplement testing capabilities. Rather than relying on a single laboratory that may subcontract specialist analyses elsewhere, we route each project directly to the laboratory best equipped to perform it. This direct-to-source approach gives our clients access to specialist methods including HPLC, LC-MS/MS, ICP-MS and other category-specific techniques — while helping deliver competitive pricing, faster turnaround times and the right analytical method for every project.

Experience

Collectively, our team has over 6 decades of experience spanning food supplement manufacture, and chemical/biological testing – positioning us with a perfectly balanced understanding of both the food supplement industry/regulatory landscape, and the necessary scientific expertise to deliver.

Find Testing Too Expensive as a Consumer?

One major obstacle for consumer-level supplement testing is cost. Testing typically costs anything from £65 + VAT to upwards of £1,000 + VAT.

For a brand, diluting this cost across thousands of units, makes the per-unit testing cost negligible. But for consumers, this is quite expensive.

To address this and to put power back in the hands of consumers, we launched the Insider Program.

This is where consumers can submit and vote-on which products they would like to see tested at the lab for a nominal fee of £6.99 if paid Monthly, or £60 if paid Annually.

You also get immediate access to our catalogue of over 200 prior test results and the 3 new test results that we post to the program each week.

WHAT OUR CLIENTS SAY

John Clarke Supplements

Tobias Porter

Consumer

I've taken the same brand of fish oil for over 7 years, and never questioned their quality. A friend told me about Verifier Lab, and with all the concerns over fish oils containing high levels of heavy metals and PCB's, I thought I'd give them a try. Suffice to say, the results put my mind at rest! Thank you

Gina Tamwell

Consumer

I wanted to find out how much of my Vitamin C supplement I was actually absorbing. I was taking timed-release due to the body's ability to only absorb so much at once, but I was concerned that it was passing through my system before it had fully dissolved/absorbed due to this. So I sent it off to Verifier Lab to check the disintegration and dissolution rates. Very insightful!
