What is NAD+ and What Does It Do For Cellular Health?
In the world of health and longevity, there’s one molecule that’s been making waves for its important role in cellular health: NAD+. Short for Nicotinamide Adenine Dinucleotide, NAD+ is a coenzyme present in every cell of our body, and it’s often called a “helper molecule” for good reason.
It helps in converting the food we eat into energy and supports vital functions like repairing damaged DNA. However, as we age, our natural NAD+ levels start to decline, which can affect everything from metabolism and energy to our cells’ ability to repair themselves.
This drop in NAD+ is linked to a range of age-related issues, including lower energy, slower metabolism, and an increased risk of chronic diseases.
So, what exactly does NAD+ do for our cells, and why is it essential for staying healthy as we get older?
In this article, we discuss…
- The critical role of NAD+ in maintaining cellular health
- What happens when your NAD+ takes a dive (and why it matters)
- Effective ways to supercharge your NAD+ levels for peak performance and longevity
What is NAD+?
NAD+ (nicotinamide adenine dinucleotide) is a molecule that drives hundreds of critical metabolic processes inside our cells, acting as a cellular energy shuttle. First discovered in 1906 by scientists studying fermentation in yeast, NAD+ isn’t just another biochemical compound.
It’s a direct participant in cellular energy production, moving electrons and triggering repair signals. When you consume food, NAD+ helps break down nutrients and convert them into usable cellular energy.
Picture your cells as intricate machines. NAD+ serves as both the fuel line and the maintenance crew, making sure everything operates as efficiently as possible. It shuttles electrons during metabolic reactions and alerts cellular systems when something needs fixing.
Here’s where things get interesting – and a bit frustrating. As we age, our NAD+ levels take a nosedive, typically dropping by half between our 20s and 80s. It’s one of biology’s cruel jokes: just when we need cellular efficiency the most, our NAD+ supply starts dwindling.
The science behind this decline is pretty fascinating. Your cells face a double setback: they start producing less NAD+ while simultaneously using more of it to repair accumulated damage. It’s like trying to feed a growing family with a garden that keeps shrinking.
Thankfully, your body has multiple ways to make NAD+. It can be created from tryptophan (yes, the amino acid in turkey), from vitamin B3, or by recycling existing NAD+ molecules. This versatility has sparked intense research interest, with scientists discovering that NAD+ is involved in over 500 different cellular reactions – quite a resume for one tiny molecule!
This has led to exciting developments in aging research, including promising approaches using precursor molecules like nicotinamide mononucleotide (NMN) and nicotinamide riboside (NR). Understanding how to maintain healthy NAD+ levels through various pathways could be one of the keys to healthier aging.
The Discovery of NAD+
The story of NAD+ began in a humble laboratory in 1906, when two British biochemists made a puzzling observation while studying yeast. Sir Arthur Harden and William John Young noticed something extraordinary: when they added boiled yeast extract to fresh yeast, the fermentation process unexpectedly accelerated. The mysterious compound they had stumbled upon, which they dubbed “cozymase,” would later become known as NAD+ (Nicotinamide Adenine Dinucleotide).
The scientific community quickly recognized the magnitude of this finding, and researchers around the world began unraveling the secrets of the molecule. Hans von Euler-Chelpin made significant strides in the 1920s and 1930s, mapping out NAD+’s chemical structure and identifying its key components – sugar, adenine, and phosphate. His groundbreaking work, along with Harden’s initial discovery, earned them both the 1929 Nobel Prize in Chemistry. The breakthrough continued when Otto Heinrich Warburg discovered in 1936 that NAD+ contained a special pyridine ring that could transfer hydrogen atoms, explaining how it helped cells transform nutrients into energy.
As research techniques improved, scientists gradually mapped out NAD+’s complete structure and began to understand its true importance in the cell. What started as a curious observation about yeast fermentation led to one of biochemistry’s most crucial discoveries. NAD+ turned out to be essential not just for fermentation, but for DNA repair, gene expression, and cellular communication – making it a fundamental molecule for life itself.
What’s the Purpose of NAD+ in the Human Body?
NAD+ switches between two states: NAD+ (oxidized) and NADH (reduced). This molecular switch enables core cell operations like energy production, DNA maintenance, and cell communication.
As an electron carrier, NAD+ moves electrons during metabolism. When reduced to NADH, it delivers electrons to the transport chain that generates ATP – the basic fuel cells need. The continuous conversion between NAD+ and NADH maintains energy flow through major pathways like glycolysis and the citric acid cycle1.
NAD+ supplies key materials to DNA repair enzymes called PARPs2. When NAD+ runs low, DNA damage builds up, which can raise the risk of cancer. Research shows that higher NAD+ levels strengthen DNA protection3.
Through its influence on sirtuins, NAD+ regulates how genes turn on and off by modifying chromatin proteins.4 This shapes aging patterns and metabolic function.
NAD+ also helps create signaling molecules like cyclic ADP-ribose (cADPR) that coordinate calcium movement and other essential cell activities.
Put simply, NAD+ supports energy production, DNA repair, gene regulation, and cellular signaling. Maintaining healthy levels of NAD+ is instrumental for cellular health and resilience, helping us achieve better health and longevity.
What Happens If You Have Low NAD+?
Since NAD+ is involved in processes like energy production, DNA repair, and cellular signaling, low levels can disrupt these vital functions and lead to symptoms of NAD+ deficiency, as well as a range of health issues affecting metabolism, brain function, and heart health.
When it comes to metabolic disorders, declining NAD+ levels are linked to issues with glucose and lipid metabolism. This can result in insulin resistance5, a major factor in metabolic syndrome—a condition characterized by obesity, high blood pressure, and abnormal cholesterol levels. Research published in Frontiers in Endocrinology found that people with lower NAD+ levels had a higher prevalence of metabolic diseases, including hypertension and diabetes6.
NAD+ also supports brain health by maintaining the energy production and DNA repair mechanisms that support neurons. In conditions like Alzheimer’s and Parkinson’s diseases, NAD+ levels are often lower, which may accelerate neurodegeneration7.
Low NAD+ levels can also negatively impact heart health. The heart requires a lot of energy to function, and NAD+ is essential for maintaining efficient energy production.
Reduced NAD+ levels can impair mitochondrial function, leading to lower ATP production and a higher risk of heart failure. This has been supported by a study published in the Frontiers in Physiology, where researchers discovered that NAD+ metabolism disruptions are closely linked to cardiovascular conditions, such as ischemic heart disease and heart failure8.
Ultimately, low NAD+ levels can have wide-reaching effects on metabolism, brain function, and cardiovascular health. But through optimizing your NAD levels, you can prevent or manage these issues for better health outcomes.
Benefits of NAD+ for Cellular Health
Beyond its all-important role in energy production, NAD+ offers a remarkable array of benefits for cellular health that make it indispensable for optimal functioning.
One of its most significant advantages is its ability to activate enzymes called sirtuins, which act as cellular stress sensors9. When activated by NAD+, these sirtuins help cells adapt to various forms of stress, from metabolic fluctuations to environmental challenges, essentially functioning as cellular guardians that promote resilience and longevity.
The health benefits of NAD+ also include maintaining robust cellular communication networks, particularly through a process called ADP-ribosylation. This process helps cells respond appropriately to damage or stress signals, ensuring they can coordinate their responses effectively.
We can think of NAD+ as a cellular emergency response system. When one part of the cell detects a problem, NAD dependent signaling helps mobilize the appropriate repair mechanisms, maintaining cellular health and preventing potential dysfunction.
In essence, the importance of NAD cannot be overstated for sustaining cellular vitality, promoting healthy aging, and improving our overall quality of life as we grow older. It’s not just about energy, but about thriving as you age.
Can NAD+ Truly Slow Aging?
If you’re hoping to feel younger and stay healthy as you age, boosting your NAD+ levels might be the answer. NAD+ has become a buzzword in anti-aging research, with growing evidence suggesting it can help slow down the aging process by improving cellular health.
For example, research published in Frontiers in Aging found that supplementing with NMN (a precursor to NAD+) can improve energy levels and insulin sensitivity, both crucial for healthy aging10.
In this 60-day study, participants took 300 mg of NMN daily, leading to an impressive 38% increase in NAD+/NADH levels by day 60. Meanwhile, those on a placebo saw minimal changes. The NMN group also reported better quality of life and stable insulin sensitivity, while the placebo group experienced declines. This shows that NMN can effectively boost NAD+ levels, improve energy, and support better metabolic health.
Another study in Nature Communications looked at nicotinamide riboside (NR), another NAD+ booster. Participants took 500 mg twice daily for six weeks. The results showed a significant increase in NAD+ levels, improving several metabolic health markers. Although major changes like blood pressure were not observed, the rise in NAD+ suggests that it could help enhance overall cellular function11.
A long-term study published in Scientific Reports explored how NMN impacts cardiovascular health in older adults12. For 12 weeks, participants took 250 mg of NMN daily. While their blood pressure didn’t change much, there was a positive trend toward reducing arterial stiffness, a sign of better cardiovascular health. This suggests NMN might help support heart health as we get older.
These findings suggest that keeping your NAD+ levels up could help slow the progress of age-related diseases. It not only helps boost energy and improve metabolism but also supports healthy blood sugar levels and may even protect your heart.
Replenishing NAD+ Levels in Your Body
Supporting your NAD+ levels helps maintain cell health and can slow down signs of aging. While lifestyle changes like regular exercise, calorie restriction, and consuming foods high in NAD precursors can support the body’s NAD+ production, their impact often diminishes as we get older.
Opting for a more targeted approach—combining NAD+ testing with strategic supplementation of NAD precursors—can be much more effective to naturally increase NAD levels.
The truth is, there isn’t a one-size-fits-all approach to optimizing NAD+ levels, so the first step is to assess where your levels currently stand — are they lower than they should be, at baseline, or optimized?
Knowing this will help you determine the right dosage of NAD+ supplementation for your needs.
An Intracellular NAD+ test serves as an effective diagnostic tool in this context. Testing your NAD+ levels is the most effective way to figure out the optimal dosage for you.
Ideally, you should measure both at baseline and after supplementation. At a minimum, testing after supplementation is essential, as the same dosage may work differently for different people—it could be optimal, ineffective, or even toxic. An NAD+ test provides you with actionable data to help you optimize both your NAD+ levels and your overall health.
If you’re already taking NAD+ supplements, using NAD+ IV infusions, injections, or patches, it’s crucial to test your levels to ensure these products are actually working. Many products on the market don’t deliver the desired results, or they don’t work as effectively as they claim.
