Key Takeaways
______________________________
Did you know that as you age, your body’s levels of NAD+—a critical coenzyme found in every cell—begin to decline? This decrease is linked to many age-related conditions, from a drop in energy levels to reduced cognitive function.
But there’s good news: boosting NAD+ can have significant anti-ageing benefits, helping you maintain energy, health, and vitality. In this blog, we’ll explore how NAD+ supports longevity, why it declines with age, and how you can restore these levels to feel your best as you age (R).
What Is NAD+?
Before diving into the benefits, let’s take a quick look at what NAD+ is and why it’s essential for your health. NAD+ (nicotinamide adenine dinucleotide) is a coenzyme that plays a critical role in cellular energy production, DNA repair, and maintaining healthy metabolism. As we age, our NAD+ levels naturally decrease, leading to a range of age-related health issues. But by increasing your NAD+ levels, you can potentially slow down the ageing process and support overall longevity (R).
This image shows how ageing cells experience NAD+ decline due to increased activity of consumers like CD38 and PARPs, along with reduced NAMPT enzyme expression, limiting NAD+ recycling and contributing to age-related decline.
Enhanced Cellular Energy Production
One of NAD+’s primary functions is supporting cellular energy metabolism. It does this by playing a critical role in oxidative phosphorylation, a process that helps produce ATP, the energy currency of your cells. As NAD+ levels decline with age, your cells lose efficiency in energy production, leading to fatigue and reduced vitality.
Studies have shown that maintaining healthy NAD+ levels helps sustain energy production, promoting better physical performance and cognitive function (R, R). This means that boosting NAD+ through supplements or lifestyle changes can improve your energy levels, making you feel more vibrant and active as you age.
Restored Mitochondrial Function
Mitochondria, often referred to as the “powerhouses” of the cell, are responsible for producing energy. However, as we age, mitochondrial function declines and NAD+ depletion is a major contributor to this process. Without sufficient NAD+, mitochondria struggle to perform optimally, leading to a decrease in energy and an increase in age-related diseases.
Boosting NAD+ can restore mitochondrial function, improving both cellular health and longevity. Research shows that supplementing with NAD+ precursors, like NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside), can enhance mitochondrial function, helping to improve overall energy production and vitality (R).
DNA Repair and Longevity
Another essential function of NAD+ is its role in DNA repair. Every day, your cells are exposed to factors that can cause DNA damage, including environmental toxins, UV radiation, and even normal metabolic processes. If this damage accumulates, it can accelerate the ageing process and increase the risk of diseases like cancer (R).
NAD+ is a cofactor for PARP enzymes, which are responsible for repairing damaged DNA. When NAD+ levels decline, so does your body’s ability to repair DNA, leading to cellular ageing. Supplementing with NAD+ can support DNA repair mechanisms, helping your body fight against the effects of ageing and maintain youthful cell function (R).
Anti-Ageing Effects Through Sirtuins
Sirtuins, a family of proteins that regulate cellular health, are heavily dependent on NAD+. These proteins control key processes like inflammation, mitochondrial biogenesis, and stress resistance—all of which are crucial for longevity. As NAD+ levels decrease, sirtuin activity diminishes, leading to a decline in these protective processes (R).
By increasing NAD+, you can enhance sirtuin activity, which may extend lifespan and improve overall health. Animal studies have shown that increasing NAD+ levels activate sirtuins and improves longevity by promoting healthier ageing at the cellular level (R).
Neuroprotection and Brain Health
As we age, cognitive decline becomes a significant concern for many. NAD+ levels are linked to neuroprotection, particularly in neurodegenerative conditions like Alzheimer’s and Parkinson’s disease. Mitochondrial dysfunction and reduced energy production in brain cells are key features of these diseases, and NAD+ plays a vital role in supporting both mitochondrial health and cognitive function (R).
Research indicates that boosting NAD+ levels can have neuroprotective effects, helping to preserve brain health and reduce the risk of neurodegenerative diseases (R). This makes NAD+ a powerful tool for maintaining mental clarity and cognitive sharpness as you age.
Metabolic Health and Weight Management
Maintaining a healthy metabolism is key to preventing conditions like obesity, diabetes, and cardiovascular disease—all of which are more common as we age. NAD+ plays an essential role in metabolic processes, including insulin sensitivity, fat oxidation, and energy balance.
Supplementing with NAD+ precursors like NMN and NR has been shown to improve insulin sensitivity and support fat metabolism, reducing the risk of diet-induced obesity in animal studies (R, R). By improving metabolic health, NAD+ can help you maintain a healthy weight and reduce the risk of chronic disease as you age.
Supporting Immune Function
NAD+ is also crucial for supporting a healthy immune system, particularly in regulating immune cell function and inflammation. As we age, the immune system weakens, making it harder to fight off infections and chronic inflammatory conditions. By increasing NAD+ levels, you can enhance both the innate and adaptive immune response, which helps your body better combat infections and inflammation (R).
Muscle Function and Recovery
Muscle health is another area where NAD+ has shown significant benefits. As NAD+ levels decline with age, so does muscle function and recovery. Supplementing with NAD+ precursors can promote better muscle strength, endurance, and recovery by enhancing mitochondrial function in muscle cells.
Studies suggest that restoring NAD+ levels can improve muscle regeneration, allowing for faster recovery and greater physical performance as you age (R). This is particularly beneficial for those looking to stay active and maintain muscle mass into their later years.
Cardiovascular Health
Cardiovascular diseases are among the leading causes of death worldwide, and ageing is a significant risk factor. NAD+ supports vascular health by promoting healthy endothelial function and reducing oxidative stress, both of which are crucial for maintaining cardiovascular health.
Research has shown that boosting NAD+ can protect against cardiovascular diseases by improving blood vessel function and reducing inflammation (R). This highlights NAD+’s role not only in longevity but also in protecting the heart and circulatory system as we age.
How to Boost NAD+ Levels
The good news is that you can restore NAD+ levels naturally through supplements like NMN and NR, as well as lifestyle changes. Regular exercise, a healthy diet, and proper sleep are all linked to higher NAD+ levels, helping to support overall longevity.
Incorporating NAD+-boosting supplements into your daily routine can enhance energy, promote better cellular health, and protect against age-related decline (R).
Conclusion
NAD+ is a powerful tool in the fight against ageing, offering benefits from improved cellular energy to enhanced brain and cardiovascular health. By boosting NAD+ levels, you can take proactive steps to support longevity, vitality, and overall wellbeing.
