NAD+ is essential for various biological processes such as energy production, DNA repair, cell survival, and even the regulation of circadian rhythms.
As we age, the NAD+ levels in our bodies begin to decline. This can lead to cellular aging, metabolic disorders, and other health problems.
NR supplementation is considered a powerful strategy to boost NAD+ levels in the body, promoting cellular health, improving energy metabolism, and potentially slowing down aging.
However, while NR presents promising benefits, it is essential to understand its potential side effects and the correct dosage to ensure safety and efficacy.
The origin and development of NR
Nicotinamide Riboside was first discovered in the early 20th century when scientists explored milk components. They identified a unique compound that eventually came to be known as NR .
However, it was only in the 21st century that its remarkable properties and potential benefits were fully recognized.
In 2004, a significant breakthrough in NR research occurred when Dr. Charles Brenner, a renowned biochemist, discovered that NR was not just a form of vitamin B3, but also a potent precursor to the vital coenzyme, Nicotinamide Adenine Dinucleotide (NAD+) . This discovery catapulted NR to the forefront of anti-aging and cellular health research.
Brenner and his team further identified that NR could be converted into NAD+ more efficiently than other NAD+ precursors.
This property made NR a promising candidate for addressing the age-related decline in NAD+ levels, an issue linked with various health problems such as metabolic disorders, neurodegenerative diseases, and the overall process of aging.
Since this groundbreaking discovery, numerous research initiatives have been undertaken to understand the full potential of NR.
Various scientific studies have focused on its possible benefits for cellular health, brain function, metabolic regulation, and longevity.
Meanwhile, NR’s safety, side effects, and appropriate dosage are also being explored to ensure this powerful supplement can be effectively used in daily health regimes.
What are the health benefits of Nicotinamide Riboside?
NR has come under the scientific spotlight due to its many potential health benefits. By boosting NAD+ levels in the body, NR is a potent supplement capable of enhancing various aspects of human health.
1. Enhances cellular health
NR is a precursor to NAD+, a coenzyme that plays a crucial role in cellular metabolism and energy production. It’s a linchpin molecule that connects our diet with our cellular health, transferring the energy from the food we eat into a form that cells can use to perform vital functions.
As we age, the levels of NAD+ in our body start to decline naturally, leading to a decrease in cellular energy production and overall function. This process is linked with various signs of aging and age-related diseases .
As a precursor to NAD+, NR can effectively increase the body’s NAD+ levels, potentially reversing the age-related decline in cellular health. Doing so improves energy metabolism at the cellular level, helping cells function optimally, repair themselves, and resist stress more effectively.
2. Promotes longevity
The aging process is a complex phenomenon involving numerous cellular changes. A vital component of these changes is decreased Nicotinamide Adenine Dinucleotide (NAD+) levels in our bodies as we age. NAD+ is essential for maintaining cellular function, repairing DNA, and overall cellular health.
As a potent precursor to NAD+, NR has demonstrated promising potential in addressing age-related decline in cellular health. By boosting NAD+ levels, NR may effectively combat the aging process at the cellular level.
Research shows that NR supplementation can restore NAD+ levels in older cells to those comparable to younger cells, thereby improving their function and vitality. This can lead to a delay in the onset of age-related physiological changes and contribute to overall longevity.
Furthermore, NR’s role in promoting DNA repair is critical in the context of aging. As we age, our cells’ ability to repair DNA damage decreases, which can lead to cell death and contribute to aging and age-related diseases. By boosting NAD+ levels, NR enhances the cells’ ability to repair DNA, potentially slowing the aging process.
It’s also worth noting that NR’s potential anti-aging effects extend beyond cellular health. Studies suggest that it may contribute to improved brain function, cardiovascular health, and metabolic regulation – all crucial to maintaining health and vitality as we age.
3. Improves brain health
As NAD+ levels naturally decline with age, the capacity of neurons to function optimally and resist stress can decrease, potentially leading to neurodegenerative diseases.
As a potent NAD+ precursor, NR can help replenish the dwindling NAD+ levels, potentially benefiting brain health in several ways.
- Neuroprotection: Studies suggest that NR can protect neurons from damage and degeneration. By increasing NAD+ levels, NR helps bolster the energy metabolism of brain cells, making them more resistant to stress and less prone to degeneration.
- Cognitive function: NR may support cognitive function by improving cellular health and energy production in brain cells. Preliminary research suggests that NR supplementation can enhance memory and learning abilities, though more human studies are needed in this area.
- Brain aging: As we age, decreased NAD+ levels can lead to diminished brain function and increased susceptibility to neurodegenerative diseases. By boosting NAD+ levels, NR may slow brain aging and support healthy brain function in older adults.
4. Enhances metabolic rate
NR’s potential in boosting metabolism is primarily due to its ability to increase NAD) levels in the body which helps convert the food we eat into energy, thereby playing a critical role in regulating metabolism.
As we age, NAD+ levels naturally decrease, which can lead to a decrease in metabolic efficiency. This decline in metabolic rate can contribute to weight gain and difficulties in losing weight. By boosting NAD+ levels, NR can enhance metabolic function, leading to more efficient energy usage and potentially aiding in weight management.
Moreover, some studies suggest that NR supplementation could activate sirtuins, a protein group that regulates cellular health and metabolism . This activation could further enhance metabolic function and potentially support weight loss.
However, while the potential of NR in metabolism and weight loss is promising, it’s important to understand that NR is not a magic bullet for weight loss. The effectiveness of NR supplementation for weight loss will also depend on other factors such as diet, physical activity, and overall lifestyle.
5. Boosts heart health
The heart is a highly active organ that requires constant energy to function optimally. NAD+ plays a crucial role in energy production in heart cells, and a decline in NAD+ levels, particularly with aging, can impact heart function.
By boosting NAD+ levels, NR may help maintain heart health in several ways:
- Promotes energy metabolism: By increasing NAD+ levels, NR helps enhance energy production in heart cells, allowing the heart to function efficiently.
- Improves blood flow: Some research suggests that NR could improve blood flow and vascular health, which are critical for maintaining heart health.
- Reduces cardiovascular risks: Preliminary studies suggest that NR could help reduce the risk of cardiovascular diseases by improving cholesterol levels and reducing inflammation, both of which are key risk factors for heart disease.

Generally, NR is well-tolerated, with most reported side effects being mild and temporary, but it’s important to explore the possibility of severe adverse reactions. Certain individuals may have unique responses, as with any supplement, and it’s essential to be aware of potential risks.
No serious adverse reactions have been directly linked to NR in most scientific literature. However, because the research on NR is still relatively new and long-term studies are limited, it’s possible that we are not fully aware of all potential adverse reactions, especially over an extended period of use.
A few considerations should be noted:
1. Interactions with medications
While no specific medication interactions have been documented for NR, it’s always possible that a supplement could interact with prescription or over-the-counter drugs. If you’re currently taking medication, it’s advisable to consult a healthcare professional before starting NR.
2. Pregnancy and breastfeeding
There’s a lack of safety data on using NR during pregnancy and breastfeeding. Until more is known, it’s recommended that women who are pregnant or breastfeeding avoid NR supplementation.
3. Underlying health conditions
Individuals with specific health conditions, such as liver disease or diabetes, should consult a healthcare professional before starting any new supplement, including NR.
4. High dosages
Most studies have used moderate dosages of NR. It’s generally well-tolerated at these levels. However, the safety of high-dose NR supplementation over a long period is still unclear.
What’s the recommended daily intake of NR?
Currently, there is no universally agreed-upon recommended daily intake for NR. This is partly because research on NR is still ongoing, and the optimal dosage may vary depending on several factors, including:
Since NAD+ levels naturally decrease, older adults may benefit from a higher dosage than younger adults.
Certain health conditions, especially those associated with inflammation or metabolic dysregulation, can lead to a faster decline in NAD+ levels and may require a higher dosage of NR.
Physical activity levels
Active individuals and athletes may have higher metabolic needs and, therefore may benefit from higher dosages of NR to support cellular energy production.
Certain nutrients, like tryptophan, can be converted into NAD+. People who lack these nutrients in their diet might benefit from NR supplementation.
Genetic variations can influence how effectively the body converts NR into NAD+. Some people may naturally be more efficient at this process and, therefore might require a lower dosage of NR.
Goal of supplementation
The optimal dosage can also depend on the specific health goals of NR supplementation, like enhancing cognitive function, boosting energy levels, supporting cardiovascular health, or slowing aging processes.
Most clinical studies on NR have used doses ranging from 100mg to 1000mg daily. A commonly used dosage in human studies is 300mg per day, which has been observed to increase NAD+ levels in healthy adults safely.
However, it’s important to note that just because a specific dosage is used in research does not automatically mean it’s the best dosage for everyone. Individuals may respond differently to NR, and what works well for one person may not work well for another.
It’s also worth noting that taking a higher dose does not necessarily lead to better results. Some research suggests that the body’s ability to convert NR into NAD+ might decrease with higher doses, meaning that taking more NR does not always lead to higher levels of NAD+.
Given these considerations, starting with a lower dose and gradually increasing it if needed is necessary while closely monitoring how your body reacts.
Any supplementation changes should be under a healthcare professional’s guidance.
