NMN vs NR: Unlocking the Secrets of Anti-Aging Supplements

 Are you overwhelmed by the ongoing “NMN vs NR” debate in the world of anti-aging supplements? You're not alone. With countless claims and counterclaims surrounding these two molecules, it's hard to know which one is the real deal. 

In this comprehensive guide, I will demystify the difference between NMN and NR, revealing which one might be the game-changer for your health and longevity goals. Keep reading to unlock the secrets to a healthier, more vibrant future.

Understanding NMN and NR

NMN (Nicotinamide Mononucleotide) and NR (Nicotinamide Riboside) are both precursors of NAD+ (Nicotinamide Adenine Dinucleotide), a crucial molecule involved in cellular energy production, DNA repair, and numerous other vital cellular processes. 

Due to the decline in NAD+ levels as we age, many researchers believe that supplementing with NMN or NR can support healthy aging and improve overall health.

By boosting the NAD+ levels in the body, one can potentially extend the lifespan and promote overall well-being. NMN and NR supplements are popular NAD+ boosters. 

NMN vs NR: Main Differences



NMN molecule is a larger molecule

NR is relatively smaller 

NMN is a more direct source of NAD+

NR is first converted to NMN and then into NR— adding an additional conversion step

Easily absorb by our body

Complex absorption process

NMN is quite stable

NR is unstable and quickly degrades into vitamin B3

NMN has specific cell transporter

NR doesn’t need a transporter to enter the cell due to its small size

Structurally both these molecules are almost similar— NMN has an additional phosphate group attached to it. This, in turn, increases the size of NMN and makes it difficult to enter the cells. 

Researchers believe that for successful cell entry, NMN has to be converted into NR. However, a recent study discovered a gene, Slc12a8, that creates a specific NMN transporter molecule to help NMN pass through the cell membrane.  



How NMN and NR Become NAD+ in Cells

The main difference between NMN and NR lies in their conversion into NAD inside the cells. 

Our body produces NAD through these three pathways:

  1. The De Novo Pathway: It converts tryptophan (amino acid) into NAD
  2. The Preiss-Handler Pathway: This pathway uses nicotinic acid, a vitamin B complex,  and converts it into NAD
  3. The Salvage Pathway: This pathway uses NR and converts it into NAD through an intermediary NMN.  

Our body can also recycle NAD with the help of proteins known as sirtuins. The excessive NAD is turned into nicotinamide (NAM), which in turn produces NMN with the help of the NAMPT (Nicotinamide Mononucleotide Adenylyltransferase) enzyme.

On the other hand, NR is first converted to NMN by the enzyme NRK (Nicotinamide Riboside Kinase) and then follows the same pathway as NMN to become NAD+.

Safety of NMN and NR

Both NMN and NR have been extensively studied for their safety profiles. Research has shown that both molecules are generally well-tolerated, with minimal side effects. NMN has been shown to be safe for oral administration at specific dosages in adult men. Similarly, NR presents no health risk when it is taken over long periods of time.

Bioavailability of NMN and NR

A critical factor to consider when comparing NMN and NR is their bioavailability, or how efficiently our bodies can absorb and utilize them. Studies have shown that NMN is quickly absorbed and converted to NAD+ in tissues, while NR has a more complex absorption process. The difference in bioavailability might impact the effectiveness of each supplement, but more research is needed to draw definitive conclusions.

Stability and Storage of NMN and NR

Proper storage is crucial for maintaining the potency of your supplements. NMN is known to be sensitive to heat and humidity, so it's essential to store it in a cool, dry place, preferably refrigerated. In contrast, NR is relatively more stable and can be stored at room temperature without significant degradation.

Dosage of NMN and NR

The optimal dosage of NMN and NR can vary depending on individual factors such as age, health status, and personal goals. While there is no one-size-fits-all approach, typical dosages range from 250 to 500 mg daily for both supplements. It's always best to consult with a healthcare professional for personalized recommendations.

Is NMN Better than NR for Longevity?

Given their similarities, it's challenging to determine which supplement is better for longevity. Studies have suggested that NMN might be more effective due to its higher bioavailability and stability. Moreover, there is strong evidence that NMN improves symptoms related to aging, while NR lacks such scientific backing. 

 For instance, one study suggests NMN's role in muscle endurance to many folds. Another finding concluded that NMN can help in treating metabolic diseases. Interestingly, a mouse Alzheimer's model showed a reduction in the beta-amyloid protein levels— a key cause of the disease. 

For these and many other discoveries, many companies are using NMN for therapeutical purposes. The US military and NASA are also using NMN to prevent aging and promote health.

Alternatives to NMN

While NMN and NR have captured the spotlight, other ingredients can also serve as alternatives to NMN. One such ingredient is Pterostilbene, a naturally occurring compound found in blueberries and grapes, known for its potent antioxidant and anti-inflammatory properties. Another alternative is Resveratrol, a well-known polyphenol found in red wine, which has been extensively studied for NMN potential health benefits.


Both NMN and NR offer promising potential in the field of anti-aging and overall health. While they share many similarities, factors such as bioavailability, stability, and individual response may influence which supplement is the better choice for you.

As a knowledgeable consumer, I encourage you to continue exploring the world of anti-aging supplements and stay informed about the latest developments in this exciting field. By staying up-to-date, you can make the best choices for your health and longevity.

In the ever-evolving world of anti-aging supplements, the NMN vs NR debate will likely continue to intrigue and inspire further research. As more studies are conducted, and new findings emerge, I'll be here to keep you informed, helping you navigate the complex landscape of anti-aging and overall health. Stay tuned for more insights and breakthroughs in this fascinating field!
