EXCELLENT 4.9 based on 41 reviews

The only brand I will use, other brands make me feel nautious

When I take other brands on empty stomach my body feels very bad and I feel like vomit. But with this brand I don't feel anything bad. I take on morning and one night. I bought the whole package. I waited one month before write a review. I feel very good and will now take the subscription.

Noticeable differences in weeks and highly recommend this product

I was skeptical at first, but the lab tests convinced me to give it a try. In just a few weeks, I've seen noticeable improvements in my skin and overall well-being. Highly recommend!

Recommended NMN from very youthful 50 year old friend

Started NMN on a friend's recommendation. Can't say it's been life-changing, but I do feel slightly more alert and less tired by the end of the day. The effects are not huge, but for someone in their late 40s like me, every little bit helps.

Good supplement for 50 and older

Two months in, and the change in my energy levels is subtle but real. It’s not a cure-all, but as an addition. I like it for the science, I do feel a bit more 'alive' each day. At my age, every bit of vitality counts. I am 56 and my kids want me to take other stuff too


Verified Buyer

My kids buy for me

After retiring, my kids buy me this. My friends also talk about aging a lot. I've been taking it for a few months now, and I've noticed increase in my energy and brain. It's a valuable to me daily routine. My kids feel good i take it.

4 Months of NMN

Been using NMN for a couple of months now. I can say I've noticed changes, but there's a subtle difference in how I feel daily, this is a good sign and you're supposed to take NMN for at least 6 months. Less foggy in the brain, maybe? It's pricey, but there is no limit how much I will spend on my health


Verified Buyer

Good stuff, Arrived fast

Took NMN for a month now. Surprisingly, I feel a tad more vibrant each day. Didn't expect much, but it's pleasingly noticeable


Verified Buyer

I believe in the science of this

After reading a fair bit about NMN and its potential anti-aging benefits, I decided to give it a go. While the scientific community still seems divided, I personally have observed some improvement in my overall wellbeing. It's no magic pill, but the science behind it is intriguing enough to keep me going.

What is NAD+?

Healthy aging is linked to NAD+ levels

Research featured in the prestigious journal Nature Aging indicates a significant correlation between levels of NAD+ and overall health during human aging.

NAD+, short for nicotinamide adenine dinucleotide, is a critical compound present in every cell of the human body. This molecule plays a vital role in numerous biological processes, acting as a key player in the metabolic reactions that power our cells and, by extension, our entire bodies. Its presence and function are fundamental to maintaining cellular vitality.




Unfortunately, NAD+ levels decline with age.

NAD+ levels by age

Age in years

Studies indicate that starting anti-aging efforts in your 30's is optimal. Incorporating NAD+ enhancers like NMN into your daily regimen can rejuvenate NAD+ levels to what they were in your 20's, effectively aiding in the anti-aging process.

Renowned Harvard scientist David Sinclair defends this stance with his research, highlighting the critical role of sirtuins - a family of proteins that depend on NAD+ and are essential for cellular health. Sirtuins regulate cellular processes like DNA repair, inflammation reduction, and mitochondrial function. NMN, a precursor to NAD+, is crucial in this process as it helps replenish declining NAD+ levels, effectively rejuvenating cells and mirroring the vitality experienced in one’s 20s.

Sinclair’s studies affirm the significant impact of NAD+ and NMN in promoting longevity and combating the signs of aging.

Day 60

Your body has been at an elevated NAD+ level for 30 days. The NAD+ in your body is enhancing your heart's cellular energy, crucial for its continuous beating. It's actively fighting oxidative stress and reducing inflammation, key factors in heart health. Simultaneously, it's aiding in the repair of your heart cells.

Day 180

You’re at the 6 month mark. Your most notable improvement is the cellular energy in your brain, which is crucial for cognitive functions like memory and acuity. This increase in NAD+ is actively supporting your neurons, boosting the energy metabolism within your brain cells, maintaining and improving your mental acuity and memory functions.

Day 365

Well done, you’ve completed 365 days of MASI NMN. This marks just the beginning of your graceful aging journey.
