- "October 21" "I have only just begun taking these supplements. After reading the reviews and seeing that they were third-party tested, I decided to switch from my previous brand to ForYouth. So far, I am pleased with my choice. I'll need to take them a bit longer before I can give a fair review. but I appreciate that I only need one pill a day."

- "January 13" "I wanted to come back and say The Repair was really as good as the reviews said. Not going back."

"But it does happen! The Repair is a slow burn but once it kicks in you know it. you feel it with more energy at the back end of the day, and mood is better, calmer. you notice your nails growing, not splitting. skin glows a little more. i subscribe now and I have never committed to any other product online before. it doesn't replace other supplements like magnesium or vitamins, it just is part of a my daily routine now."

The Secret What’s Happening In Your Body Causing That Bone-Deep Fatigue 40s and 50s

NAD+ is your cells' energy currency – it controls how your mitochondria produce energy, how your body repairs DNA, and how your brain maintains focus. But most supplements ignore what's actually accelerating its decline.


As you age, an enzyme called CD38 rises sharply, actively breaking down NAD+ faster than your body can replace it. It's a double hit: production drops while destruction ramps up. If a formula doesn't block CD38 first, any NAD+ you add gets consumed before your cells can use it, which is why most NMN supplements produce inconsistent results.

The NMN brand that actually works. Because it's built differently

Uthever® NMN — 450mg

Uthever® NMN — 450mg The NAD+ precursor your cells actually convert.

Uthever® is the most clinically studied branded NMN ingredient in the world. 99%+ verified purity. Manufactured under European GMP standards. TGA-listed in Australia. Every batch comes with an independently verifiable Certificate of Analysis.

Why this matters: when researchers tested the top-selling NMN products online, more than half contained little to no actual NMN. Uthever® is used in published clinical trials — including a double-blind study showing a 38% NAD+ increase above baseline.

This isn't anonymous powder from an unverified source. It's the NMN that scientists actually use in their research

Meet Our Scientists

Dr. Jan Gruber, PhD, is a biochemist and Associate Professor at the National University of Singapore (NUS), specialising in ageing biology, mitochondrial function, and oxidative stress.


His research explores the molecular mechanisms of longevity and has been published in leading journals. He completed his PhD in Biochemistry at the University of Oxford and also studied physics and mathematics at the University of Cambridge.


His work often uses simple organisms such as tiny worms (C. elegans) to understand how ageing happens at the cellular level, and to test new ways to slow it down.
