NMN (Nicotinamide Mononucleotide) is a molecule that helps boost NAD+ levels, which naturally decline with age. This decline is linked to chronic inflammation, aging, and diseases like Alzheimer’s, heart disease, and diabetes. Research shows that NMN can reduce inflammation, improve cellular repair, and enhance mitochondrial function, making it a key tool for healthier aging.
Key points to know:
- What NMN Does: Boosts NAD+ levels, activates sirtuins (proteins that repair cells), and reduces oxidative stress.
- Inflammation Types: Acute (short-term, like after an injury) and Chronic (long-term, linked to aging and disease).
- Benefits of NMN: Lowers inflammatory markers, supports gut health, and improves energy production.
- Research Insights: Animal studies and early human trials show NMN reduces inflammation and improves metabolic health.
- Lifestyle Pairing: NMN works best with a healthy diet, exercise, and good sleep.
While promising, more research is needed on dosage, long-term safety, and its effects on specific conditions. For now, NMN supplements, combined with lifestyle changes, offer a way to support longevity and reduce inflammation.
NMN Inhibits Chronic Inflammation | Study Review By Modern Healthspan
How NMN Affects Inflammatory Pathways
NMN influences inflammation through three primary mechanisms that work to restore cellular health.
NMN Increases NAD+ Levels
The anti-inflammatory benefits of NMN are closely tied to its ability to restore NAD+ levels. As a direct precursor to NAD+ [6], NMN is efficiently converted into this vital molecule inside cells. Unlike other compounds that require multiple steps for conversion, NMN is transported directly into the cytoplasm by the enzyme Slc12a8 [3]. Once inside, NMN is rapidly transformed into NAD+, which is essential for energy production and cellular repair. Research indicates that NMN supplementation can reduce activation of the TLR4/NF-κB p65 and MAPK pathways, which are associated with inflammation. This happens through increased NAD+ levels, which help lower TLR4 signaling, reducing inflammatory responses, reactive oxygen species, and apoptosis markers [5]. Additionally, boosting NAD+ levels supports metabolic processes, a stress response mechanism conserved across various species [6]. This restoration of NAD+ creates the foundation for improved cellular repair.
NMN Activates Sirtuins for Cellular Repair
Higher NAD+ levels from NMN supplementation also activate sirtuins, a group of proteins essential for managing inflammation and repairing cells. Sirtuins depend on NAD+ to function and are involved in repairing DNA damage and regulating inflammatory pathways [5]. These proteins work by removing chemical tags from other proteins via deacetylation and also engage in modifications like demalonylation, desuccinylation, and mono-ADP-ribosylation [7]. By suppressing genes linked to inflammation and enhancing cellular maintenance, sirtuins help break the cycle of chronic inflammation. Their activity also supports mitochondrial health, which is a critical factor in controlling inflammation.
NMN Reduces Oxidative Stress and Improves Mitochondrial Function
NMN also addresses inflammation by tackling mitochondrial dysfunction and oxidative stress - two factors closely tied to chronic inflammation. As mitochondria age, they become less efficient and produce more reactive oxygen species, which can damage cells and trigger inflammatory responses. NMN counters this by boosting mitochondrial NAD+ levels and activating SIRT3, which deacetylates mitochondrial proteins to improve their function [8]. This process lowers reactive oxygen species in the hippocampus by enabling SIRT3 to deacetylate mitochondrial manganese superoxide dismutase (SOD2) [8].
Animal studies highlight NMN's protective effects. For example, in a severe hemorrhagic shock model, rats treated with NMN showed reduced lactic acidosis and lower serum IL-6 levels, a key inflammatory marker [8]. NMN also helped maintain NAD+ levels and prevented mitochondrial dysfunction in the liver and kidneys during extreme stress [8]. Additionally, skeletal muscle from NMN-treated mice demonstrated improved maximal respiration rates when exposed to a mitochondrial uncoupler, further emphasizing NMN's role in enhancing energy production and reducing oxidative stress [9].
Research on NMN's Anti-Inflammatory Effects
Expanding on NMN's role in boosting NAD⁺ levels and activating sirtuins, recent research highlights its potential to regulate inflammation and promote healthier aging. Both animal studies and early human trials provide evidence of these anti-inflammatory benefits. Let’s take a closer look at how these effects are demonstrated in animal models and human studies.
Animal Studies on NMN and Inflammation
Research in animal models reveals that NMN can significantly reduce markers of chronic inflammation while supporting tissue repair and overall organ function.
- Atherosclerosis in Mice: In ApoE−/− mice fed a high-fat diet, NMN supplementation lowered pro-inflammatory cytokines like Tnfα, Il-1β, Il-6, and Mcp-1. At the same time, it boosted anti-inflammatory markers such as Arg-1, Mrc-1, Retlna, and Irf-4. Notably, plaque collagen increased by 51%, suggesting improved vascular health [11].
- Alzheimer’s Disease Models: In Alzheimer’s mouse models, NMN showed promising effects by reducing inflammation, preventing synaptic loss, and decreasing amyloid plaques and β-amyloid production. These benefits were linked to the inhibition of the JNK pathway [10].
- Bone Injury in Rats: In rats with aluminum-induced bone injuries, NMN helped mitigate bone loss, oxidative stress, and inflammasome activation, highlighting its potential in bone health [10].
- Gut Health in Aged Mice: NMN improved gut structure and function in older mice by replenishing NAD⁺ levels and activating SIRT3 and SIRT6. These sirtuins are critical for antioxidant and anti-inflammatory functions as well as maintaining the gut barrier. This is particularly significant since gut inflammation often contributes to broader systemic issues [10].
Human Clinical Trials
Preliminary human trials suggest NMN supplementation can elevate NAD⁺ levels and improve metabolic functions. For instance, taking 250 mg of NMN daily for up to 12 weeks increased NAD⁺ levels by as much as 2.57 times in healthy participants [12].
These higher NAD⁺ levels have been linked to several health improvements, including:
- Enhanced aerobic capacity and muscle performance
- Reduced blood pressure and glucose levels
- Increased telomere length in peripheral blood mononuclear cells [12]
Additionally, some studies propose that NMN may rejuvenate adult metabolism, making it function more like that of someone 10 to 20 years younger [3]. This growing body of evidence has not only fueled scientific interest but also driven commercial growth. The global NMN market, valued at $252.7 million in 2020, is projected to reach $385.7 million by 2027 [12].
Areas for Future Research
While these findings are promising, there are still important questions to address before NMN can be fully established as a reliable anti-inflammatory treatment.
- Optimal Dosage and Duration: More studies are needed to determine the best dosing strategies for different populations [13].
- Targeted Applications: Future research should explore NMN’s effects on specific health conditions, such as NAD⁺ deficiency, sarcopenia, and its combined use with exercise. Studies comparing NAD⁺ precursors for conditions like obesity and non-alcoholic fatty liver disease are also critical [13][15].
- Long-Term Safety: Comprehensive clinical trials and toxicity studies are essential to fully understand NMN’s safety profile, especially for long-term use [4][14].
- Age-Related Conditions: As NAD⁺ levels decline with age - by 70% in skin, 30% in the liver, and 10–25% in the brain - there is a need to investigate how supplementation could address age-related cardiac and other systemic issues [13][15].
These research directions will help clarify NMN’s therapeutic potential and pave the way for broader clinical applications.

Using NMN in Daily Longevity Routines
With research highlighting NMN's anti-inflammatory potential, incorporating it into your daily routine could be a smart step toward better health. The key lies in understanding how to use NMN effectively, pairing it with complementary strategies, and choosing products that deliver measurable results.
NMN Supplements for Inflammation Control
NMN supplements provide a practical way to replenish NAD+ levels, which naturally decline with age. By middle age, NAD+ levels drop to about half of what they were in youth [3]. This decline is linked to cellular aging and chronic inflammation, making supplementation an essential tool for maintaining cellular health.
While NMN is found in some foods, supplements deliver a concentrated dose that's needed to make an impact. Timing your dose is also important. Taking NMN in the morning on an empty stomach may enhance energy and focus, while evening doses could aid in rest and cellular recovery [16]. Experiment with both to discover what works best for you.
Consistency is key. Regular supplementation is essential to see results [16]. The growing interest in NMN reflects its potential, with the U.S. market projected to reach $46.36 million in 2024 and grow at a rate of 6.0% annually through 2031 [16]. This growth is fueled by the rising demand for personalized NMN protocols tailored to factors like age, BMI, and health objectives [16].
To maximize NMN's benefits, combine it with broader lifestyle strategies.
Combining NMN with Other Longevity Strategies
Pairing NMN with healthy lifestyle choices can enhance its anti-inflammatory effects. Diet plays a major role here. Cutting down on sugar supports AMPK and sirtuin activation, while focusing on unrefined carbs and healthy fats - like those in nuts, seeds, oily fish, and avocados - can further boost results [17]. Diets like the Mediterranean or vegetarian, rich in polyphenols, complement NMN's effects by providing additional anti-inflammatory benefits.
Exercise is another powerful ally. Physical activity naturally increases NAD+ levels and reduces inflammation. Aim for 150 minutes of moderate aerobic exercise or 75 minutes of vigorous activity each week, alongside resistance training twice weekly [17]. Together, these activities amplify NMN's impact on cellular function and inflammation.
Gut health also plays a role. Research shows that NMN positively affects gut barrier function in aging mice. A diet rich in fiber and probiotics supports beneficial gut bacteria, contributing to overall inflammation control [17].
Finally, consider your environment. Reducing exposure to pollutants and toxins - by monitoring air quality and using air purifiers - can lower your body's inflammatory load, allowing NMN to work more effectively [17]. These combined strategies help support cellular repair and longevity.
As Dr. Mark Hyman notes: "Chronic decline in our health, the shrinking of our health span, the increased morbidity, is a result of pathological processes that we can treat. And if we now think about the fundamental problems that go wrong as we get older as treatable, then we can actually create a society where our health span equals our lifespan." [17]
Selecting Quality NMN Supplements
Choosing a high-quality NMN supplement is critical, especially since 70% of NMN products on the market may not be genuine [21]. Here's what to look for:
- Purity: Opt for supplements with at least 98% purity or higher [20]. This ensures you're getting the active ingredient without unnecessary fillers or contaminants.
- Third-party testing: Check for certificates of analysis (COAs) from independent labs. These verify the product's purity, potency, and safety [18][20].
- Reputation and transparency: Choose brands that are open about sourcing, manufacturing, and testing processes [18][20]. Reliable companies will provide detailed information about their quality control measures.
