Science-Backed NMN, Without Compromise

World’s 1st Clinically-Proven
& No.1 NMN Ingredient Brand in the USA


Uthever® fromEffePharmis a powerful NAD+ precursor that has been extensively researched in both human and animal scientific studies, with over 20 publications validating its efficacy. Some of the best studied areas are its use in anti-ageing, skin health, gut health, sports performance, pneumonia and rare diseases. The health benefits in these areas are observed in children and adults, under health conditions and various medical conditions.

Blood Cellular NAD+/NADH

Specifically, the Uthever® group showed an 11.3 percent increase in NAD+/NADH levels at day 30 and a remarkable 38 percent increase at day 60, compared to the placebo group’s 14.3 percent rise.

6-Minute Walking Endurance Test

Walking endurance also demonstrated a positive effect, with a 6.5 percent increase in the Uthever® group at day 60, while the placebo group remained unchanged.

SF-36

Similarly, the SF-36 questionnaire, which serves as an indicator of subjects’ overall well-being, indicated enhanced well-being in the Uthever® group at day 60, showing almost double the increase compared to the placebo group.

The Best Quality NMN Guaranteed

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.

✔ 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.
