Know The Difference

DON’T BE FOOLED. Many over-marketed supplements are mass-produced overseas using cost-cutting formulas built around fillers, binders, and low active doses. Some are marketed as “UK made” despite being manufactured abroad. Without a COA or heavy metal test, consumers are left trusting branding and hype rather than verified results.

Why We Exist

We’re Andrew & Richard, brothers and founders of CLNLABS®.

CLNLABS® was built on a simple belief: the supplement industry should do better. Too many products are underdosed, padded with unnecessary ingredients, or hidden behind vague blends designed to maximise profit rather than results. We refuse to play that game.

As a small, family-run business, we only create supplements we would confidently take ourselves. Every product is developed with a clear purpose and built around purity, performance, and transparency — nothing more, nothing less.

If we can’t source the highest-quality ingredient available, we don’t release the product. We believe in quality over quantity, always.

We don’t just claim our supplements are tested — we prove it. We publish our Certificates of Analysis & Heavy Metal Testing so you can see exactly what you’re taking.

Your health is long-term. Your supplements should be too.

✔ Certificates of Analysis for every batch

We provide a Certificate of Analysis (COA) for every production batch, so you can review the results for yourself. Full transparency means you don’t have to take our word for it.

✔ Third-party heavy metal tested

Every batch is independently tested for heavy metals by Eurofins.

View Testing Reports →
✔ No fillers or binders

We never use unnecessary fillers, binders, or flow agents. Every ingredient is included for a purpose — nothing more, nothing less. What you see on the label is exactly what’s inside.

✔ Fully transparent labelling

No hidden ingredients or misleading claims. We clearly disclose all ingredients, dosages, and testing standards so you can make informed choices with confidence. We never use buffered or misleading formulations to inflate numbers or obscure quality.

✔ Built on trust

Our goal has always been to provide you with the very best supplements — and the information you deserve, uncensored.

Trust isn’t bought, it’s earned, which is why we are fully transparent with our ingredients and testing.

✔ NOT CENSORED YET!

The supplement industry is often dominated by marketing, vague claims, and selective information rather than real education. We believe you deserve better. That’s why we’re committed to sharing clear, honest, and well-researched information on every supplement we offer.

By joining our email list, you’ll receive in-depth deep dives into individual supplements, where we break down the science, summarise the research in plain language, and provide full sources and links so you can verify everything for yourself.
