What is NR?
As previously discussed, Nicotinamide riboside (NR) is a form of Vitamin B3 that acts as an intermediate building block to a coenzyme in the body called nicotinamide adenine dinucleotide (NAD+). NAD+ is essential for a range of cellular processes, including energy production, DNA repair, and gene expression. However, NAD+ levels decrease as one age, making it more challenging for cells to produce enough energy to repair themselves and leading to a range of age-related health conditions.
NR has gained attention in recent years as a potential anti-aging supplement due to its ability to increase NAD+ levels in the body’s tissues. NR is safer, has better bioavailability, and is more effective at NAD+ synthesis than other precursors.
Several studies have found that supplementing with NR may help prevent or treat age-related diseases, increase longevity, and restore energy levels. However, more research is needed to fully understand the potential therapeutic uses of NR for treating cardiovascular, neurodegenerative, and metabolic disorders.
Mechanism of Action
The mechanism of action for nicotinamide riboside (NR) involves its conversion to nicotinamide adenine dinucleotide (NAD+), a coenzyme that plays a crucial role in cellular energy production and DNA repair. NAD+ is involved in several metabolic pathways, including glycolysis, the citric acid cycle, and oxidative phosphorylation. It also acts as a substrate for enzymes involved in DNA repair, such as poly(ADP-ribose) polymerases (PARPs).
NR is converted to NAD+ in a two-step process. First, NR is converted to nicotinamide mononucleotide (NMN) by the enzyme nicotinamide riboside kinase (NRK). NMN is then converted to NAD+ by the enzyme NMN adenylyltransferase (NMNAT). This conversion process replenishes cellular NAD+ levels, which decline with age. Increasing NAD+ levels through NR supplementation has been shown to improve cellular and mitochondrial function, enhance lifespan in mice, and potentially treat and prevent age-related diseases.

Increasing cellular NAD+ levels through supplementation with nicotinamide riboside (NR) has been shown to improve cellular and mitochondrial function, enhance lifespan in mice, and potentially prevent and treat age-related diseases.
One study found that chronic NR supplementation is well-tolerated and elevates NAD+ in healthy middle-aged and older adults. Another study found that repeat dose NRPT (nicotinamide riboside and pterostilbene) increases NAD+ levels in humans safely and sustainably.
NR supplementation has also been shown to improve mitochondrial and stem cell function, potentially leading to increased longevity. In addition, NR supplementation has been found to have potential benefits for treating a wide variety of age-related diseases.
These include metabolic disorders, neurodegenerative diseases, cardiovascular diseases, cancer, and inflammatory diseases. NR may also help restore energy levels and improve hyper-inflammation from the immune system.
As a result, NR has become an increasingly popular anti-aging supplement, with several studies conducted on its safety and efficacy. Further research is needed to fully understand the therapeutic potential of NR supplementation, but the current evidence suggests that it may hold promise in the fight against age-related diseases.
Metabolism and Obesity
Supplementation with nicotinamide riboside (NR) has been shown to potentially improve metabolism and increase lean muscle mass in humans. A study conducted on obese men and women found that 12 weeks of NR supplementation resulted in a significant increase in lean muscle mass and a decrease in fat mass, without any changes in body weight.
Another study on healthy obese individuals found that NR supplementation altered body composition and skeletal muscle acetylcarnitine concentrations, suggesting that NR may have potential benefits for treating metabolic disorders.
While NR may have potential benefits for metabolism and obesity, it did not seem to improve blood sugar levels, cholesterol, or inflammatory markers in a study conducted on overweight or obese middle-aged and older adults. However, more research is needed to fully understand the effects of NR on these health markers.
Overall, NR supplementation may be a promising avenue for improving metabolism and increasing lean muscle mass, but further studies are needed to confirm these potential benefits.
Cardiovascular Health
Research on nicotinamide riboside (NR) suggests that increasing NAD+ metabolism in the body may have potential benefits for reducing the risk of cardiovascular events.
One study found that chronic NR supplementation was well-tolerated and elevated NAD+ in healthy middle-aged and older adults.
Another study found that repeat dose NRPT (nicotinamide riboside and pterostilbene) increased NAD+ levels in humans safely and sustainably.
Increasing NAD+ metabolism has been shown to reduce blood pressure and stiffness of the aorta, which are both risk factors for cardiovascular disease.
These findings suggest that NR supplementation may be a promising strategy for preventing or treating cardiovascular disease.
NR supplementation has also been shown to improve mitochondrial function, which is important for maintaining optimal cardiovascular health.
Mitochondria are responsible for producing energy in the form of ATP, which is essential for the proper functioning of the heart and blood vessels.
NR has been shown to improve mitochondrial function in animal studies, and recent human studies have suggested that NR supplementation may improve mitochondrial function in humans as well.
These findings suggest that NR may be a promising therapeutic approach for preventing or treating cardiovascular disease by improving mitochondrial function and reducing the risk of cardiovascular events.
Brain Function and Memory
Studies have suggested that nicotinamide riboside (NR) may have potential benefits for improving cognitive function and memory. NR is a precursor to nicotinamide adenine dinucleotide (NAD+), a coenzyme that plays a crucial role in cellular energy production and DNA repair. As we age, NAD+ levels decline, leading to mitochondrial dysfunction and cellular damage. However, supplementing with NR can increase NAD+ levels, potentially improving brain function and memory.
To evoke an emotional response in the audience, here are four potential benefits of NR supplementation for brain function and memory:
- NR may improve cognitive function in older adults, potentially helping them maintain their independence and quality of life.
- NR may enhance memory retrieval, helping individuals remember important information and events.
- NR may help prevent or delay cognitive decline associated with aging, reducing the risk of developing neurodegenerative diseases such as Alzheimer’s.
- NR may improve overall mental clarity and focus, helping individuals perform better at work or school and improving their overall well-being.
Longevity
Moving on from the benefits of NR for brain function and memory, let’s now explore its potential in increasing longevity.
As we age, the levels of NAD+ in our body decrease, leading to a decline in cellular function and an increased risk of age-related diseases. However, NR supplementation has been found to increase NAD+ levels, potentially improving cellular function and promoting longevity.
Several studies have shown promising results in this area. One study conducted on mice found that NR supplementation increased their lifespan by up to 15%, while another study on human cells found that NR increased the lifespan of these cells by up to 30%.
Additionally, NR has been found to improve mitochondrial and stem cell function, which could contribute to its potential for increasing lifespan.
While more research is needed to fully understand the mechanisms behind NR’s potential for increasing longevity, these findings are certainly promising.
Energy and Inflammation
One potential benefit of nicotinamide riboside (NR) supplementation is its ability to restore energy levels and improve hyper-inflammation from the immune system. As we age, our cells’ ability to produce enough energy to repair themselves decreases, which can lead to a variety of age-related health conditions. NR serves as an intermediate building block to a coenzyme in the body called nicotinamide adenine dinucleotide (NAD+), which is essential for energy metabolism and cellular repair. By increasing NAD+ levels in the body’s tissues, NR supplementation may help restore energy levels and improve hyper-inflammation from the immune system.
To further understand the potential benefits of NR supplementation on energy and inflammation, here are four key points to consider:
- NR supplementation can increase NAD+ levels in the body’s tissues, potentially treating and preventing a wide variety of age-related health conditions.
