NMN vs. Resveratrol: A Comparison of Two Anti-Ageing Supplements

The pursuit of youthfulness and longevity has fueled interest in a wide array of anti-ageing supplements.

Two compounds that have gained substantial attention in recent years are Nicotinamide Mononucleotide (NMN) and resveratrol. Both NMN and resveratrol have been touted for their potential anti-ageing effects and overall health benefits.

In this article, we will delve into the world of anti-ageing supplements, comparing NMN and resveratrol in terms of their effectiveness and mechanisms of action.

Understanding NMN and Resveratrol

Before we compare NMN and resveratrol, let’s take a closer look at each compound and their roles in anti-ageing and health:

NMN (Nicotinamide Mononucleotide):

Nicotinamide Mononucleotide (NMN) is a molecule that has garnered significant attention for its role in boosting Nicotinamide Adenine Dinucleotide (NAD+) levels in cells. NAD+ is a coenzyme essential for various cellular processes, including energy production, DNA repair, and gene regulation. As we age, NAD+ levels tend to decline, which has led to the exploration of NAD+ precursors like NMN as potential anti-ageing supplements. NMN is believed to increase NAD+ levels, supporting cellular functions and potentially countering certain age-related processes.


Resveratrol is a natural polyphenol found in certain plants, particularly in the skin of red grapes, berries, and peanuts. It gained fame for its presence in red wine and its potential health benefits, often referred to as the “French paradox.” Resveratrol is known for its antioxidant properties and its role in activating sirtuins, a class of proteins associated with longevity and cellular repair. It has been studied for its potential to mimic the effects of calorie restriction, which is known to promote longevity in various organisms.

Mechanisms of Action: How NMN and Resveratrol Work

Both NMN and resveratrol influence various cellular pathways and processes, which can contribute to their potential anti-ageing effects. Let’s examine how each of these compounds works:

NMN Mechanisms of Action:

NAD+ Precursor: NMN serves as a precursor to NAD+, a coenzyme critical for cellular energy production. By increasing NAD+ levels, NMN supports the efficient functioning of mitochondria, the cellular powerhouses responsible for ATP production.

Sirtuin Activation: NMN indirectly activates sirtuins, a class of proteins that play a role in cellular repair, DNA maintenance, and gene regulation. Sirtuins are known to be involved in various anti-ageing mechanisms.

DNA Repair: Elevated NAD+ levels, supported by NMN, can enhance the activity of enzymes involved in DNA repair, helping to maintain genomic stability and counteract age-related DNA damage.

Reduction of Inflammation: NMN has shown potential in reducing chronic inflammation, which is a known contributor to the ageing process and age-related diseases.

Resveratrol Mechanisms of Action:

Sirtuin Activation: Resveratrol is a known activator of sirtuins, particularly SIRT1. Sirtuins are involved in various cellular processes, including DNA repair, cellular stress response, and metabolic regulation.

Antioxidant Properties: Resveratrol acts as an antioxidant, neutralising harmful free radicals in the body. This antioxidant capacity can help protect cells and tissues from oxidative stress, a key factor in aging.

Mimicking Calorie Restriction: Resveratrol has been shown to activate pathways similar to those induced by calorie restriction. Calorie restriction is associated with increased lifespan in various organisms.

Anti-Inflammatory Effects: Resveratrol has demonstrated anti-inflammatory properties, which can help mitigate chronic inflammation, a common feature of ageing and age-related diseases.

A Comparative Analysis of NMN and Resveratrol

Now that we’ve explored the mechanisms of action for both NMN and resveratrol, let’s compare these two anti-ageing supplements in various aspects:

1. Effectiveness:

NMN: NMN’s primary mode of action is to increase NAD+ levels, supporting mitochondrial function and cellular energy production. While it has shown promise in animal studies, its long-term effects on human ageing are still being researched, and its effectiveness in humans remains a topic of ongoing investigation.

Resveratrol: Resveratrol’s effectiveness in promoting longevity and combating age-related diseases has been the subject of numerous studies. Research has shown that resveratrol can extend the lifespan of various organisms and offers potential benefits for cardiovascular health, metabolic health, and cognitive function.

2. Bioavailability:

NMN: NMN is water-soluble and can be absorbed relatively easily in the gastrointestinal tract. However, it is quickly metabolised in the liver, which can affect its bioavailability.

Resveratrol: Has low bioavailability due to rapid metabolism and poor absorption in the gut. To overcome this limitation, various forms of resveratrol supplements have been developed, such as micronised resveratrol and resveratrol with enhanced absorption.

3. Safety:

NMN: NMN is generally considered safe, with limited reported side effects in short-term studies.

Resveratrol: Resveratrol is also considered safe when used in moderation. However, some concerns have been raised about potential interactions with medications and its safety in high doses. It’s essential to consult with a healthcare professional before using resveratrol, especially if you are taking medications.

4. Dosage:

NMN: The optimal dosage of NMN for anti-aging purposes is still a subject of research and debate. Dosages can vary between individuals, and more studies are needed to determine the most effective dosing regimens.

Resveratrol: Dosages of resveratrol supplements can also vary, but typical recommendations range from 250 mg to 500 mg per day. Again, it’s essential to consult with a healthcare professional to determine the appropriate dosage for your specific needs.

5. Potential Synergy:

NMN and Resveratrol: Some individuals opt to take both NMN and resveratrol supplements together, believing that the combination may offer synergistic benefits for anti-ageing. While there is no conclusive evidence to support this claim, ongoing research may shed more light on potential interactions between these compounds.


NMN and resveratrol are two anti-ageing supplements that have captured the imagination of those seeking to maintain youthful vitality and longevity. Both compounds have unique mechanisms of action, with NMN primarily focused on NAD+ support and resveratrol on sirtuin activation and antioxidant protection.

While research on both NMN and resveratrol is ongoing, it’s important to note that the effectiveness of these supplements in extending human lifespan and promoting healthy ageing is still the subject of scientific inquiry.

As with any dietary supplement, it is crucial to consult with healthcare professionals to ensure their safe use and effectiveness for your specific health goals. Additionally, maintaining a healthy lifestyle through proper nutrition, regular exercise, stress management, and other positive habits remains fundamental to the pursuit of longevity and overall well-being.
