- "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."

Here’s what two longevity professors have to say about your fatigue
Something has changed in you when compared to you in your 30s. And it wasn't your discipline.
You've fixed your sleep. You exercise. You eat well. And your body still isn't rewarding the effort.
That's not a willpower problem. Something specific is happening inside your cells.
Every cell in your body runs on a molecule called NAD+. It's what your mitochondria use to produce energy, repair DNA, and keep you sharp. By your 40s and 50s, your NAD+ levels may have dropped by half.
But it gets worse. An enzyme called CD38 increases with age, and its primary function is to consume NAD+. Your body is producing less fuel AND something is actively eating what's left.
Experts are literally calling CD38 the energy-eating enzyme that’s consuming your energy molecule!
Preclinical research found that inhibiting CD38 preserved approximately 70% of the NAD+ that would otherwise be destroyed.
If you're navigating perimenopause at the same time, you're being hit from two directions, hormonal shifts pulling energy from one side, cellular fuel Loss pulling from the other. Perimenopause gets all the attention. The cellular side goes completely unaddressed.
This is why your fatigue feels disproportionate. Why "doing everything right" hasn't been enough. Your effort is real. The system that should respond to it has been running on empty.
The obvious solution
(and the problem with it)
If NAD+ is the fuel, can you just top it up? Yes — through a compound called NMN.
There's just one problem. CD38 doesn't stop consuming NAD+ just because you've added more. It eats the new supply too. This is why many women feel a short burst of energy on standard NMN — then watch it fade. The NMN worked. CD38 ate the result.
It's like filling a bathtub without plugging the drain.
Two longevity professors at the National University of Singapore designed a formula that works in the order biology demands:
Step 1: Block The Drain With Apigenin
ApiAge® Apigenin — a naturally occurring flavonoid — is a targeted inhibitor of the CD38 enzyme. Harvard-published research found that inhibiting CD38 can preserve approximately 70% of the NAD+ that would otherwise be broken down.
This is the step that every other NMN product skips.
Step 2: Restore the reserves.
With CD38 addressed, Uthever® NMN — 99%+ pharmaceutical-grade purity, manufactured under European GMP standards — can do what it's designed to do. NMN is the most direct precursor to NAD+. Your cells convert it into usable cellular fuel.
Without CD38 consuming it on arrival, the NMN actually reaches your mitochondria.
Step 3: Activate what you've restored.
Pterostilbene supports the cellular longevity pathways that put your restored NAD+ to work — helping your cells use that energy for repair, recovery, and sustained function.
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

Frequently asked questions
How does The Repair work?
The Repair is a supplement that helps your cells stay healthy and repair damage by boosting and maintaining NAD⁺ levels. It combines three ingredients: Uthever® NMN to raise NAD⁺ levels in your body, ApiAge® Apigenin to stop NAD⁺ from being used up too quickly, and Pterostilbene — a highly bioavailable polyphenol that amplifies the effectiveness of NAD⁺ while adding powerful antioxidant support. Together, they sustain your energy, focus, skin, and overall well-being.
What daily dosage do you recommend?
We recommend to take one capsule of The Repair per day. One capsule of The Repair contains 450 mg of NMN. This is the maximum daily dose that is allowed for this vitamin B3-variant by the Health Sciences Authority (HSA) in Singapore.
However, research has shown that NMN is safe and well tolerated at least up to 900 mg per day, as shown in a recent paper by Yi, Maier, et al. (2023).
Is The Repair safe? Any side effects?
Yes, NMN (Nicotinamide Mononucleotide), a vitamin B3 variant, is generally considered safe for human consumption based on several human trials. NMN is generally free from side effects when used as directed. Rarely, some individuals may experience mild digestive discomfort. If you have any concerns, discontinue use and consult a healthcare provider.
Here are some key studies that support the safety of NMN:
A 2019 study by Irie, J., et al., published in the Endocrine Journal, assessed the safety of NMN in healthy Japanese men. The researchers administered various doses (100 mg, 250 mg, 500 mg) of NMN and found it to be safe and well-tolerated, with no significant adverse effects observed.
A 2023 study by Yi, Maier, et al., evaluated the safety and bioavailability of NMN in healthy adults. It found that NMN was safe and well-tolerated at doses up to 900 mg, with no significant adverse effects.
Apigenin is a natural flavonoid found in various fruits, vegetables, and herbs (especially parsley), commonly consumed in a normal diet. Apigenin is considered safe, even at high doses, and no toxicity has been reported.

Pterostilbene is a naturally occurring polyphenol found in blueberries, grapes, and other plants, closely related to resveratrol. It is generally considered safe when consumed in foods or as a supplement within recommended doses. Studies suggest it is well tolerated, with no significant toxicity reported in humans. Rare side effects may include mild gastrointestinal discomfort or, at very high supplemental intakes, slight changes in cholesterol or liver enzyme levels.
What is the best time of day to take The Repair?
Take The Repair in the morning, ideally with a small meal. After waking, your NAD⁺ levels naturally rise; taking NMN then gives that process an extra boost. A little dietary fat also helps the polyphenols apigenin and pterostilbene absorb better.
Fasting? That’s fine too. You can take The Repair on an empty stomach — NMN absorbs well — though uptake of the fat-soluble polyphenols apigenin and pterostilbene may be slightly reduced.

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.
