What is NMN?

NMN (nicotinamide mononucleotide) is a direct precursor to NAD+, a molecule involved in energy production and regeneration processes in practically every cell. NAD+ levels decline with age.

How do I take it?

Simply stir your portion into water or a cold drink, preferably in the morning as a fixed part of your routine. The powder is tasteless.

What does 99% purity mean?

At least 99% of the powder is pure NMN (Uthever®), without fillers and binders. Each batch is additionally tested for purity and heavy metals in accredited German laboratories; the test report is available for inspection.

Who is NMN suitable for?

For everyone who wants to establish their longevity routine long-term. We do not recommend taking it during pregnancy and breastfeeding, and if you are taking medication, please consult your doctor beforehand.

NMN + NAD+The principle behind it

NMN is the direct precursor to NAD+, central to your cells' energy and regeneration.

For womenOur Vision

Longevity research too often overlooks women. We're changing that, with science by women for women.

Lab-tested in GermanyOver 99% purity

Each batch is tested in accredited German laboratories, without fillers.

What to expect

Day 1

Your routine starts

One serving, one glass of water, done. NMN is rapidly absorbed and is available to your body as a direct NAD+ building block.

Week 1 to 2

Your body is working

In your cells, NMN is converted into the coenzyme NAD+. It is involved in over 500 enzymatic reactions, from energy metabolism to cell function.

Week 4 to 8

Persistence pays off

NAD+ is consumed and regenerated daily. Your daily dose ensures a constant supply, consistency trumps perfection.

Month 3+

Your routine carries you

Behavioral research shows: On average, it takes about ten weeks for a new habit to become automatic. From now on, NMN is simply part of your day.

Every body is different, testimonials are individual and do not guarantee results. Food supplements are not a substitute for a balanced diet and a healthy lifestyle.

I've been taking it for about three months and love it. I wake up faster, my head feels clearer, and I have more energy, but it's even, all day long. No jitters, no crash like with other 'energy' products. Just calm and consistent.

I've been taking this NMN for a few weeks now and I'm really happy with it. I feel more awake in the mornings and have a little more energy throughout the day. It feels like a high-quality product and I haven't experienced any side effects.

The changes are subtle, but I'm less tired in the afternoons. It takes a bit of patience. There's no immediate effect, but I can tell it's working. I'm sticking with it and will see how it develops.

I used to be so hooked on Coffee but now since I started using NMN, I do not drink it anymore and my energy is way more stable. I've been taking it for more than 2 months now and it also helps me with recovery from all the intense training I have weekly. But the energy aspect is really great! Thank you so much!

Love this product! It’s my second bag already, since I noticed such an improvement with my mood and energy levels 😊

Pouches might look small, but they’re VERY long lasting, as you need only small amount daily!

Also I’m always looking forward to this little morning ritual as the small bubbles, that appear during mixing look soooo mesmerising 🫧 🌊

Miriam Janke, Gründerin LongevityLife.

Mich hat schon immer eine Frage fasziniert: Wie können wir unseren Körper dabei unterstützen, gesünder zu altern? Nicht, indem wir gegen die Zeit ankämpfen. Sondern indem wir unseren Zellen genau das geben, was sie wirklich brauchen, um voller Energie, widerstandsfähig und lebendig zu bleiben. Genau das hat mich dazu gebracht, NMN in unser Sortiment aufzunehmen. Ich bin selbst ein großer Fan dieses NAD⁺-Boosters.

Als Gründerin teile ich nur, was ich auch selbst lebe. Und dieses NMN-Pulver wurde schnell zu einem meiner täglichen Rituale. Was es so besonders macht, ist seine Reinheit: über 99 % zertifiziertes NMN in pharmazeutischer Qualität. Komplett frei von Füllstoffen, Konservierungsmitteln und künstlichen Zusätzen. Es wird in Deutschland auf Schwermetalle und Reinheit laborgeprüft und basiert auf Uthever® NMN – derselben Form, die in der weltweit größten klinischen NMN-Studie eingesetzt wurde. Das gibt mir ein tiefes Vertrauen in die Qualität. Gerade weil es da draußen so viele minderwertige Produkte gibt.

Auch die Wissenschaft dahinter finde ich unglaublich spannend. NMN ist ein direkter Vorläufer von NAD⁺, dem Molekül, auf das jede unserer 37,2 Billionen Zellen angewiesen ist. Für Energie, DNA-Reparatur und Regeneration. Ab Ende zwanzig sinkt unser NAD⁺-Spiegel ganz natürlich. NMN hilft, ihn wieder aufzufüllen. Das unterstützt so vieles: die Energieproduktion in den Mitochondrien und die ATP-Bildung, den Schutz vor oxidativem Stress, die Aktivierung der Sirtuine – unserer Langlebigkeitsgene –, den Erhalt der Telomere und sogar die sichtbare Hautgesundheit.

Ich liebe den Gedanken, dass ich mit diesem kleinen Löffel jeden Tag meine Zellen auf die grundlegendste Weise unterstütze und ihnen helfe, länger jung zu bleiben.

I have been taking this for about three months now and I honestly love it. Out of all the supplements I use, this one is my clear favorite.

I actually look forward to taking it in the morning because I feel the difference pretty quickly: I wake up faster, my head feels clearer, and I have more energy, but in a steady way that lasts all day. It also helps me stay focused and get through my work without feeling distracted or hitting that usual afternoon slump.

What I really appreciate is that it doesn’t make me jittery and there’s no crash later on. With other “energy” products I’ve tried, I always get highs and lows - with this one, it just feels smooth and consistent.
I also feel like my general health has been better since I started. I haven’t been sick at all this winter.

All in all, I can highly recommend this product and I am excited about trying other products of this brand!!
