    Have been taking NMN now for well over a year and I can’t imagine ever wanting to give it up. I’m much more focused, less tired, and have a wonderful renewed energy. Results were not immediate but accumulated over a few months. I love this life-enhancing supplement.

    My favorite NMN powder among all brands (I tried them a lot). I did research, and I know that all of them purchase NMN from China, but it means a lot to test the products in the laboratory and ensure their quality. Youth and Earth have NMN with the smallest amount of heavy metals, in fact – insignificant.

    I have been taking NMN now for about four months. I take one 250 mg capsule a day. I am 71 and have noticed a big difference in my skin — my face is starting to look younger with less wrinkles and I also seem to have more energy.

    I’m mid-30’s and have been taking NMN for a while now. My skin becomes noticeably softer/smoother to touch and my energy levels are higher. Don’t be fooled by dodgy companies on Amazon — stick with quality solid brands when it comes to your cellular health.

    You can actually feel it working! I get a gentle uplifting feeling and my whole day is then so much better. I feel better, I can concentrate better, my gym workouts are better. So many benefits and it’s obvious the quality is just incredible. Very different to most other brands as it really is sublingual and results feel immediate.

    I am a health, wellness, fitness and longevity professional. I spend a third of my time researching, a third putting research into practice and a third helping others navigate their needs. I have used this product for several years and it is the best.

    Been taking this powder for over a year now and wouldn’t be without it. Recently was quite unwell so I upped my dose and it made the world of difference to my recovery.

    This is my second lot of NMN. I just feel so much better when I take it. I am 51 years old and I started to feel sluggish. I did extensive research and this product kept coming up. At first I was put off by the price but then again you get what you pay for! This particular brand seemed to be the most pure form of NMN. Anyway, I’ve been on it 3 months, I take 2 scoops a day directly under my tongue and let it dissolve. Within 3 months my hair is growing, I can’t remember the last time I had pain in my joints, my skin looks healthy and generally I feel great! This month I started taking it with resveratrol and that gives me such an energy boost. So to round it off — ignore the price as it’s worth every penny! I don’t normally leave reviews but I had to for this.

    At age 84, 250 mg of NMN daily has slowly improved my dry eye symptoms, which had become increasingly problematic. It has also improved my energy levels.

    I’ve been taking NMN 250mg capsules x 2 daily for around 7 weeks now. I wasn’t sure much was happening initially but around the 3-4 week mark I noticed that I was sleeping better. Falling asleep faster and staying asleep all night (which as a menopausal woman is amazing) and I also noticed that my nails have stopped splitting and breaking and are actually growing again and are much stronger. For those 2 things alone I decided to persevere. I was yet to see any major differences to my energy or skin. Last weekend I decided to up my dose to 750mg daily after doing some research about dose and age and I am impressed! I’ve been waking up feeling refreshed and alert which is unheard of for me, and I’ve had much more energy this week than for a very long time. I’ve also noticed I have more stamina when am out walking. I met a friend at the weekend who told me that I look younger than ever and I hadn’t even told her about taking NMN! I am delighted with the results in the first week of increasing my dose. I’ve had no side effects at all from these supplements which confirms to me their high quality. I’ve since recommended them to my friend!

    I purchased the NMN powder & I have been using it for over 2 months. I have noticed a huge difference in my energy levels, my sleep patterns & my recovery after a workout... So far I love it & am looking forward to discovering more benefits with continued use.

    Having carefully researched for a good, trustworthy company, I’m more than happy with Youth and Earth. I feel absolutely safe with the purity, reliability and quality of their NMN. Y&E also offer prompt communication with any query and can be trusted for their careful guidance and advice with all of their products. Thank you 👏

What NMN Is

NMN (Nicotinamide Mononucleotide) is a natural molecule that is a direct precursor to NAD+, a coenzyme for cellular energy metabolism, DNA repair and metabolic function

Why It Works

Research shows NAD+ levels decline with age so NAD+ maintenance is key to healthy aging.

NMN works as a powerful battery at a cellular level. It promotes energy and recovery by boosting the body’s natural NAD+ production

A Note From Youth & Earth founder

Edward van Harmelen

“We created NMN for people who want more out of their days — and their years.

Clean sourcing, transparent testing, and science explained in plain English. No noise, no gimmicks — just real support that fits real life. I’ve been taking NMN for eight years now. I’m 52, and I’ve been able to maintain my energy, focus, and drive through all those years. Discovering how powerful targeted nutrients can be in supporting our bodies was a true game changer for me. I believe age is a privilege — and the way we live it is a choice. It’s not just about adding years to life, but adding life to those years — staying active, fulfilled, and ready for what’s next.”

Straight Answers to Common Questions

Yes! Every batch of our NMN is third-party tested for purity, potency, and heavy metals to ensure you’re getting exactly what’s on the label, and nothing else. NMN (β-Nicotinamide Mononucleotide) is a naturally occurring molecule found in all living cells and has been widely studied for its role in cellular energy and healthy ageing. If you have a medical condition or take prescription medication, we always recommend consulting a healthcare professional before starting any new supplement.

Our NMN powder, taken sublingually under your tongue, goes directly into your bloodstream and starts to work immediately. Our NMN capsules are just as effective, but they have to reach your stomach first before they start working. Both contain the same high-quality NMN, the choice simply depends on your routine. Capsules are best for convenience and consistent daily dosing, powder offers more flexibility, allowing you to adjust your dosage. Either way, you’re supporting your NAD⁺ levels with pure, bioavailable NMN.

Whilst some people notice an instant boost in energy, others notice steadier energy, clearer focus, and improved mood within the first few weeks. And for others, the effects are more subtle, working quietly at the cellular level to support mitochondrial function, DNA repair, and resilience over time. Think of it as a long-term investment in your biological energy, not an instant stimulant.

We recommend taking NMN first thing in the morning on an empty stomach. This timing helps align with your body’s natural circadian rhythm and NAD⁺ production, which peaks earlier in the day, supporting consistent daytime energy and focus. We find that NMN delivers best results when consumed on an empty stomach, so we recommend to wait for at least 20–30 minutes before consuming any food or coffee/tea.

Yes, but start simple. Take NMN on its own for 2–4 weeks to let your body adjust and to notice how it feels. Once you’ve established a baseline, you can stack it with other NAD⁺-supporting or longevity nutrients such as Resveratrol, Glutathione, or Spermidine for a more comprehensive protocol.
