Unlocking the Secrets of NAD+: NMN vs NR
In our search for answers to slowing the aging process, NAD+ is a promising target. It is a critical coenzyme that plays a vital role in cellular functions and aging. As we age, our NAD+ levels decline by about 1% per year, leading to various age-related conditions. There are two powerful precursors that can boost NAD+ levels: Nicotinamide Mononucleotide (NMN) and Nicotinamide Riboside (NR). While they both serve the same purpose, they have one major difference, in the form of a phosphate group, just one small change in their molecular structure. We’re going to walk through the world of NAD+ precursors, examining the science, benefits, and best uses of NMN and NR supplementation.

1. The Importance of NAD+
Before we discuss the differences between NMN and NR, let’s pause to review the role of NAD+ in our bodies. Nicotinamide Adenine Dinucleotide (NAD+) is a coenzyme that participates in numerous critical processes, including cellular energy production, DNA repair, and sirtuin activity. Without NAD+, these processes cannot occur, and life as we know it would cease to exist.
As we age, our NAD+ levels decline, leading to a wide range of age-related conditions. Various factors, such as stress, alcohol consumption, intense exercise, and lack of sleep, can further deplete our NAD+ levels. This decline in NAD+ has been recognized as a hallmark of aging and is associated with cardiovascular impairment, age-related cognitive decline, and uncontrolled cell growth.
To combat these age-related changes, scientists have turned to NAD+ precursors like NMN and NR. These precursors can be converted into NAD+ and have shown promising results in animal studies and early human research. Let's now explore the world of NMN and NR and uncover their potential in enhancing our NAD+ levels and promoting healthy aging.
2. Understanding NMN
The Path to NAD+: NMN as a Precursor
Nicotinamide Mononucleotide (NMN) is a derivative of Vitamin B3 naturally produced in the body and found in various fruits and vegetables. NMN serves as a precursor to NAD+, meaning it is a building block required for the production of NAD+. Studies conducted on animals have shown that NMN supplementation can increase NAD+ levels, activating sirtuins and prolonging the lifespan of yeasts, worms, and mice. While animal studies are promising, more research is needed to fully understand the effects of NMN supplementation in humans, though human results are equally encouraging.
Animal Studies and Human Research
Recently, Professor Andrea Maier conducted a study that demonstrated the safety and efficacy of NMN supplementation in humans. The study showed that NMN supplementation increased NAD+ levels in the blood and had a positive impact on endurance and general health conditions. These findings provide valuable insights into the potential benefits of NMN in promoting healthy aging.
Potential Benefits of NMN Supplementation
The benefits of NMN supplementation extend beyond increasing NAD+ levels. Studies have shown that NMN can improve blood glucose management, enhance aerobic capacity, and exhibit cardio- and vasoprotective actions. It also decreases oxidative stress, and protects against impairments in heart health. Additionally, NMN has shown promising effects on cognitive function, synaptic plasticity, and neuronal health, since it supports apoptosis, a process that helps maintain cognitive health as we age. Furthermore, NMN may play a role in improving metabolic disorders such as gaining excess body fat and certain liver conditions linked to lifestyle factors.
3. Unveiling NR
The Role of NR in NAD+ Production
Nicotinamide Riboside (NR) is another form of Vitamin B3 that occurs naturally in minimal amounts in milk and yeast. Like NMN, NR acts as a building block for the production of NAD+. Chemically, NMN and NR are almost identical, with the only difference being the presence of a phosphate group on NMN. Research has shown that this extra phosphate group on NMN must be removed before it can enter the cell, where it is then converted into nicotinamide riboside and subsequently into NAD+. This unique characteristic of NR allows it to enter the cell more efficiently compared to NMN.
Clinical Studies and Findings
Numerous clinical studies have been conducted on NR supplementation, demonstrating its efficacy and safety in humans. These studies have shown that NR supplementation can increase NAD+ levels and improve various health outcomes. For example, NR has been found to have protective effects on cognitive function, synaptic plasticity, and motor function in models displaying forms of cognitive decline. It has also been shown to improve metabolic disorders and liver health, like NMN.
The Promising Potential of NR
NR has gained recognition for its potential in promoting healthy aging and preventing age-related physiological decline. It has been found to enhance energy expenditure, leading to a decrease in body weight and fat mass. NR also improves glucose intolerance, insulin resistance, and liver lipid accumulation. Furthermore, NR exhibits cardio- and vasoprotective actions, preventing arterial and endothelial dysfunction. The extensive research on NR supplementation highlights its potential as a powerful tool in promoting healthy aging and delaying age-related decline.
4. NMN vs NR: The Key Differences
Bioavailability and Conversion Pathways
One of the key differences between NMN and NR is their bioavailability and conversion pathways. Studies have suggested that NR has higher bioavailability compared to NMN, meaning it is more readily absorbed by the body. NR can enter the cell immediately and be converted into NAD+, while NMN requires additional steps for conversion. This difference in bioavailability and conversion pathways may contribute to the varying effects and efficacy of NMN and NR supplementation.
In terms of cell permeability, both NMN and NR enter the bloodstream rapidly after ingestion, and in animal models both compounds enter the bloodstream within 15 minutes. This means that both are typically easily absorbed in the stomach, and in some cases can be absorbed through the mucous membranes in the mouth when using lozenges or sublingual formulas.
Efficacy and Safety in Human Studies
While both NMN and NR have shown promising results in animal studies, the research on human subjects is still limited. Human studies on NR supplementation have been more extensive, providing valuable insights into its efficacy and safety. On the other hand, the human research on NMN is still in its early stages, with more studies needed to fully understand its effects on NAD+ levels and health outcomes. However, the existing studies on both NMN and NR have demonstrated their safety and potential benefits in promoting healthy aging.
Choosing What Works For You: NMN or NR?
As of now, it is difficult to determine the superiority of NMN or NR. The limited research and varying study designs make it challenging to draw definitive conclusions. While some studies have shown that NR increases NAD+ levels more effectively than NAM and NA treatments, the differences between NMN and NR in terms of NAD+ levels are still unclear. It’s important to know that both NMN and NR bypass a rate-limiting step in the production of NAD+ called the Preiss-Handler Pathway, making them both viable options for increasing NAD+ to a more youthful level. Further studies with direct comparisons of all precursors at the same dose are needed to elucidate the superiority of each one.
5. Harnessing the Power of NAD+: Anti-Aging Effects
Age-Related NAD+ Decline
One of the critical factors in the aging process is the decline in NAD+ levels. As we age, our NAD+ production decreases, leading to a decline in cellular functions. This decline in NAD+ is associated with various age-related conditions and is considered a hallmark of aging. Restoring NAD+ levels has become a focus in anti-aging research, as it has the potential to counteract the effects of aging and promote overall health and longevity.
Sirtuins and Their Role in Aging
Sirtuins, a family of proteins that depend on NAD+ levels, play a crucial role in healing the damage that accumulates with age. Sirtuins are involved in various cellular processes, including DNA repair, metabolism, and inflammation. By activating sirtuins, NAD+ can regulate these processes and potentially slow down the aging process. NMN and NR, as NAD+ precursors, can enhance sirtuin activity and contribute to healthy aging.
NMN and NR as NAD+ Boosters
NMN and NR act as powerful NAD+ boosters, increasing NAD+ levels in the body. By increasing NAD+ levels, NMN and NR can activate sirtuins and other NAD+-dependent enzymes, promoting cellular health and potentially slowing down the aging process. The ability of NMN and NR to enhance NAD+ levels has shown promising results in animal studies and early human research, paving the way for further exploration and potential therapeutic applications.
