NMN Pro Sustained Release fuels energy production, fights fatigue, and targets all 12 hallmarks of aging—supporting lasting vitality from now through your golden years.*

Cellular Energy 
Starts Here.

NAD⁺ (nicotinamide adenine dinucleotide) is a vital coenzyme found in every cell of your body, essential for converting nutrients into energy, activating DNA-repair enzymes (PARPs), and regulating sirtuins—proteins that influence gene expression and longevity. As a cornerstone of cellular metabolism, NAD⁺ supports energy production, DNA integrity, and healthy aging.*12-16  

   

By middle age, NAD⁺ levels in some tissues can drop by up to 50%, slowing down cellular repair and metabolic efficiency. One of the most effective ways to maintain NAD⁺ is with Nicotinamide Mononucleotide (NMN)—a clinically studied form of vitamin B3 that supports the body’s natural NAD⁺ production pathways, helping you feel energized, resilient, and more youthful as you age.*1,3,10-16  

The Advantage of Sustained Release

What Makes Ours Better?

NAD+ Support That Goes the Distance

NMN Pro 250™ Sustained Release is formulated as a smart-release tablet that protects NMN through digestion and delivers it gradually in the intestines 

— ensuring steady NAD⁺ support  for ongoing cellular health*18 

Fewer Doses, Better Results

Sustained release provides consistent benefits — without the need for frequent dosing. 

Steady, Lasting Energy Production

Maintain consistent cellular energy levels throughout the day—without the peaks and crashes. 

Smart Release for Better Bioavailability 

Our controlled-release tablet technology ensures maximum absorption, so your cells get more from every milligram.  

Featuring Clinically Studied Niagen® NR 

We use Niagen®, the gold standard in NAD+ research. Backed by over 400 studies and multiple human trials, it’s proven to significantly raise NAD+ levels and support mitochondrial function—essential for energy and cellular health.* 

The Technology Behind Steady 

NAD+ Support

Unlike standard NMN capsules that release all at once, NMN Pro 250™ uses a pH-sensitive gel-barrier matrix to slow and protect NMN release.  

 

This delivery system activates in the stomach’s acidic environment, forming a gel that shields NMN from degradation. As the tablet moves into the intestines, NMN is gradually released— helping maintain consistent NAD⁺ levels and cellular energy production*18 

Why Ours Is So Effective.

The Gold Standard

Uthever® NMN (Nicotinamide Mononucleotide) is the ultimate NAD+ precursor, serving as an essential building block in the NAD+ synthesis pathway*1-7,9 

Scientifically Supported

Uthever® NMN is the world’s first clinically studied NMN brand, demonstrating both efficacy and a strong safety profile in human trials*10 

37 Trillion Benefits

NMN helps fuel energy production and optimize cellular function across trillions of cells—and vital organs—throughout your body*2,4-8

Rapid Results

NMN starts boosting NAD+ levels within 24 hours, with substantial increases observed over days to weeks in a dose-dependent manner*1,2,4-7,9 

Triple Lab Tested

Every product is tested three times by independent 3rd-party labs to ensure we meet the highest standards.

Revitalize Your
Aging Cells*

Power Up Your Cells With NMN*

Nicotinamide Mononucleotide (NMN) is one of the most promising breakthroughs in longevity science. As a powerful vitamin B3 derivative and direct NAD+ precursor, it helps fuel the cellular energy, repair, and resilience needed to promote healthy, vibrant aging.*

Rebuild Your Body’s NAD+ Supply—Daily*

To maintain peak performance, your body requires a steady supply of NAD+. With NMN, you can effortlessly and continuously support your NAD+ levels. Research demonstrates that supplementing with NMN can elevate NAD+ levels in a dose-dependent manner, meaning higher doses yield greater increases in NAD+ concentrations.*1,2,4-7,9 

Fuel Cellular Energy Production*

NAD+ plays a vital role in converting food into usable energy at the cellular level. With NMN, you can optimize ATP production, leading to enhanced energy availability throughout the body. This boost in cellular energy not only supports physical performance but also contributes to enhanced quality of life.*2,4-8 

Target All 12 Hallmarks of Aging*

As we age, NAD+ levels naturally decline, making replenishment essential to support core longevity processes. NAD+ targets the root causes of aging, fueling essential enzymes like PARPs, which repair DNA and maintain cellular integrity, and activating Sirtuins, which regulate gene expression, inflammation, and stress response—key contributors to healthy aging.*1-6,8,9

How quickly can I expect results from taking NMN?

While results may vary based on a variety of factors, NMN has been shown to significantly increase NAD+ levels in humans in as little as 30 days.

What dose of NMN do leading longevity researchers take?

Most experts in the longevity field take 1000mg of NMN daily.

Will NMN help me live longer?

Some research shows that NMN may extend lifespan due to its ability to increase NAD+ levels in the body. Research shows that increasing NAD+ levels in aged animals extends their lifespan.

Are there any side effects from NMN?

Clinical research conducted on humans taking NMN shows no clinically relevant adverse effects.

I recently started taking NMN Pro 250 once a day. The most noticeable change I noticed is my skin on my face. Skin seems smoother and pores are smaller. I'm a 66 year old male and definitely don't look it.
