"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."

Why You're Tired Has Nothing to Do With Sleep, Coffee, or Willpower
the fatigue most adults feel after their 30s isn't a sleep problem. It's a fuel problem, and it starts inside your cells.
NAD⁺ is your cells' energy currency. It controls how your mitochondria produce energy, how your body repairs DNA, and how your brain stays focused. When NAD⁺ is high, you feel it. When it falls, you feel that too.
And it falls fast.
By your 40s your NAD⁺ has already dropped sharply, and by your 50s most people are running on roughly half of what they had at 20. Same person, same effort, far less fuel.
It's not just that you make less, either. An enzyme called CD38 becomes more active as you age, actively breaking down the NAD⁺ you have left. So you're losing it from both ends: making less, and burning through what remains.
This is why most NMN supplements quietly stop working.
They only do one thing: pour more NMN in the top. But you're refilling a tank that's draining out the bottom. More in, just as much out.
To raise your NAD⁺ and keep it there, you have to do two things, not one: refill it, and protect it from being drained.
That's exactly how The Repair is built.
The NMN brand that actually works. Because it's built differently

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.
Scientist's Tips
“After years of researching NAD⁺ and cellular metabolism, this is the product I always wanted to make. Take it in the morning—that’s when your cells are most ready to convert it into energy.”

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.
