Scientists are paying more attention to NAD+ weight loss strategies as they discover how this coenzyme helps burn fat and boost metabolism. This life-blood molecule plays a direct role in how well our bodies turn food into energy we can use.
NAD+ is a key compound that exists in every cell and helps drive hundreds of metabolic processes. While NAD+ does much more than help with weight, its effect on metabolism makes it especially important for people who want to improve their body composition. Our NAD+ levels drop as we get older, so the conversion of NAD+ to NADH slows down. This vital reaction powers our metabolic functions. The decline in NAD+ levels could explain why losing weight gets harder with age.
Studies show that healthy NAD+ levels can improve how mitochondria work and make metabolism more flexible. Your body might even burn fat better. NAD+ also turns on special proteins called sirtuins that control how we burn fat for energy, along with other metabolic processes.
This piece looks at the science connecting NAD+ to metabolism. You'll learn how this molecule helps manage weight at the cellular level and what you can do to boost its natural production in your body.
NAD+ and Metabolism: How It Works

Nicotinamide adenine dinucleotide (NAD+) is a fundamental molecule that powers NAD+ weight loss strategies through its role as a crucial coenzyme in cellular metabolism. Scientists found that there was this compound in 1906 that boosted fermentation in yeast. Research has since shown NAD+ to be vital for many biological processes. This remarkable molecule consists of two nucleotides joined through their phosphate groups - one nucleotide contains an adenine base while the other has nicotinamide.
The role of NAD+ in cellular energy
NAD+ acts as a vital coenzyme for redox reactions, which makes it crucial for energy metabolism. This primary electron carrier accepts hydrides from various metabolic processes and moves them to other reactions. You could call it a molecular "mailman" that delivers electrons throughout the cell.
The NAD+ benefits become clear when you look at its role in three major energy-producing pathways:
-
Glycolysis: NAD+ enables the conversion of glucose to pyruvate by accepting electrons at the sixth step of glycolysis, where glyceraldehyde phosphate dehydrogenase (GAPDH) reduces NAD+ to NADH
-
TCA cycle: NAD+ takes part in multiple mitochondrial reactions and gets reduced to NADH by isocitrate dehydrogenase 3, α-ketoglutarate dehydrogenase, and malate dehydrogenase
-
Oxidative phosphorylation: Electrons carried by NADH ended up powering ATP production through the electron transport chain
What is NAD+ goes beyond its role as a redox cofactor. It serves as a substrate for three enzyme classes: sirtuins (SIRT1-7), poly-ADP-ribose polymerases (PARPs), and cADP-ribose synthases (CD38, CD157). These enzymes employ NAD+ for essential functions like DNA repair, gene expression regulation, and cellular signaling pathways.
NAD+ can also be phosphorylated to form NADP+. Together with its reduced form NADPH, it supports antioxidant defenses and biosynthetic processes like fatty acid synthesis. This versatility makes NAD+ essential for both catabolic and anabolic reactions.
NAD+ vs NADH: understanding the redox cycle
The conversion between NAD+ and NADH represents one of biology's most crucial redox pairs. The NAD+ to NADH process happens when NAD+ accepts electrons during metabolic reactions. It essentially collects the energy released when nutrients break down. NADH then gives these electrons to the electron transport chain, which drives ATP production and regenerates NAD+.
Scientists measure this cycle through the NAD+/NADH ratio - a key indicator of cellular redox state that shows metabolic activity and cellular health. Healthy mammalian tissues typically maintain a cytoplasmic ratio of free NAD+ to NADH around 700:1, which creates ideal conditions for oxidative reactions.
The NAD+/NADH balance affects key metabolic enzymes and determines how well your body processes nutrients. Higher NAD+ levels generally promote fat-burning processes, which explains its relevance to NAD+ weight loss strategies.
Each cellular compartment maintains different NAD+ concentrations. Mouse tissue studies show mitochondrial NAD+ levels reach approximately 250 μM - up to 4 times higher than other cell areas. The outer mitochondrial membrane lets NADH move into the intermembrane space, but the inner membrane blocks NADH. Special NADH shuttles - the malate-aspartate shuttle and glycerol-3-phosphate shuttle - solve this by moving electrons instead of the NADH molecule.
NAD+ levels naturally drop as we age, which might explain decreased metabolic efficiency over time. Research has linked this decline to various age-related diseases, from cognitive issues to metabolic disorders. This makes maintaining proper NAD+ levels increasingly vital for metabolic health as we age.
How NAD+ supports metabolism
Image Source: Nature
NAD+ weight loss mechanisms work at the cellular level through this molecule's key role in energy-producing metabolic pathways. NAD+ acts as a coenzyme in over 500 different enzymatic reactions. This molecule stands at the intersection of almost all biological processes that turn nutrients into usable energy. Your body's ability to burn fat, produce energy, and maintain metabolic balance depends on NAD+.
NAD+ in glycolysis and the TCA cycle
The NAD+ benefits in metabolism start with glycolysis. This process breaks down glucose into pyruvate in the cytoplasm. NAD+ plays a crucial role in the sixth step. Here, glyceraldehyde-3-phosphate dehydrogenase (GAPDH) reduces NAD+ to NADH. This happens while glyceraldehyde-3-phosphate changes into 1,3-bisphosphoglycerate. Each glucose molecule creates two NADH molecules during this process.
Pyruvate moves into the mitochondria after glycolysis. The tricarboxylic acid (TCA) cycle then extracts more energy. NAD+ works as a coenzyme for three rate-limiting enzymes:
-
Isocitrate dehydrogenase (IDH3)
-
α-ketoglutarate dehydrogenase (KGDH)
-
Malate dehydrogenase (MDH2)
The TCA cycle reduces six NAD+ molecules to six NADH with each turn. This shows how much the cycle relies on NAD+ availability. A single glucose molecule's complete oxidation creates two NADH equivalents in the cytosol and eight NADH molecules in the mitochondria.
Impact on ATP production
The conversion of NAD+ to NADH links directly to energy production with remarkable efficiency. NADH from metabolism donates electrons to Complex I (NADH:ubiquinone oxidoreductase) in the mitochondrial electron transport chain. These electrons create a proton gradient across the mitochondrial membrane that powers ATP synthesis.
This system works with amazing productivity. Each NADH the mitochondria use creates three ATP molecules. The NADH from glucose metabolism helps produce 30 ATP equivalents. This makes up most of the 36 ATP molecules created when glucose turns completely into carbon dioxide and water.
Lower NAD+ levels reduce the activities of NAD(H)-dependent enzymes. These enzymes help with oxidative phosphorylation, TCA cycle, and glycolysis. ATP production drops as a result. This direct link between NAD+ and energy output explains why NAD+ weight loss strategies focus on healthy NAD+ levels.
Connection to metabolic flexibility
Your body's ability to switch between carbohydrates and fats for fuel depends heavily on NAD+ availability. Studies show that caloric restriction and endurance exercise boost white adipose tissue NAD+ concentrations by about 50% in mice.
Bariatric surgery helps people lose weight and improves skeletal muscle insulin sensitivity. It also increases white adipose tissue NAD+ concentration. These findings suggest that nad weight loss benefits come in part from better metabolic flexibility.
Research showed that removing NAMPT (the rate-limiting enzyme in NAD+ biosynthesis) from adipocytes affected how well mice could switch from glucose to lipids when energy input dropped. These NAD+-depleted mice showed different respiratory quotient values and glucose oxidation rates. This confirms NAD+'s vital role in metabolic adaptation.
The cytosolic and mitochondrial NADH/NAD+ redox states work closely together. These states rely on NAD+ formation from NADH through various cellular processes. This represents the essential nature of NAD+ redox potential in cellular metabolism. Rising NAD+ levels activate sirtuin proteins. These proteins modify metabolic enzymes and boost oxidative metabolism in skeletal muscle, brown adipose tissue, and the liver.
So what is NAD+ in metabolism? It serves as the molecular cornerstone that determines how well our bodies produce energy and adapt to changing nutritional states. These factors are fundamental to weight management and metabolic health.
The link between NAD+ and fat burning
The NAD+ weight loss connection becomes clear when we look at how this molecule directly affects fat metabolism. Unlike other weight management approaches that work from the outside, NAD+ works inside cells where fat burning takes place. Studies show that lower NAD+ levels relate to poor metabolic performance and make it harder to maintain a healthy weight.
How NAD+ activates fat burning
Our cells use NAD+ to burn fat through several pathways. We found that NAD+ acts as a crucial coenzyme in β-oxidation—a process that breaks down fatty acids into acetyl-CoA, which then produces energy through the TCA cycle.
When you restrict calories or exercise, AMPK (adenosine monophosphate-activated protein kinase) becomes active and increases cellular NAD+ levels. This explains why exercise remains one of the best nad weight loss strategies. Research with rats shows that exercise triggers new NAD+ production from L-tryptophan, which improves NAD+ availability.
Higher cellular NAD+ levels set off a chain of metabolic changes that help burn fat. Athletes who train for endurance show twice the amount of NAMPT (the key enzyme in NAD+ production) in their muscle tissue compared to inactive people. These higher NAMPT levels link to increased PGC-1α expression, more mitochondria, and better aerobic capacity—all of which help burn fat more effectively.
SIRT1 and SIRT3 in lipid metabolism
The connection between nad+ and fat metabolism works through proteins called sirtuins. These NAD+-dependent enzymes act as metabolic sensors that adapt to changing energy levels.
SIRT1, the most researched sirtuin, becomes active when NAD+ levels rise. Once active, SIRT1 affects several metabolic regulators:
-
PGC-1α (peroxisome proliferator-activated receptor gamma coactivator 1α)—helps create new mitochondria and improves metabolism
-
FOXO1 (forkhead box protein O1)—helps the body use fat better
-
LXR (liver X receptor)—helps remove cholesterol from cells
-
SREBP (sterol regulatory element-binding protein)—controls fat metabolism
SIRT3, found in mitochondria, targets LCAD (long-chain acyl CoA dehydrogenase) and helps burn fat directly. It also affects enzymes in the TCA cycle, which helps produce more energy from fat.
Studies show mice with more sirtuin activity handle metabolism better, burn fat more efficiently, and resist obesity from high-fat diets. In stark comparison to this, mice without SIRT1 in fat cells produce less fat-burning hormones like leptin and adiponectin.
NAD+ and mitochondrial efficiency
The process of NAD+ to NADH conversion concludes in mitochondria, where fat turns into usable energy. Studies of NAD+ precursor supplements show better mitochondrial performance. To name just one example, nicotinamide riboside (NR) supplements help mice burn fat better and stay lean despite their diet.
NAD+ improves mitochondrial performance in several ways. It increases the NAD+/NADH ratio to help the electron transport chain work better. It activates SIRT3 to optimize mitochondrial proteins. It also supports new mitochondria growth through SIRT1's effect on PGC-1α.
These improvements lead to real nad weight loss results. Nicotinamide (NAM) supplements helped obese mice lose fat and process glucose better. Protein analysis showed that NAM increased mitochondrial proteins that help with energy production, fat burning, and the TCA cycle.
High NAD+ levels also improve mitochondrial membrane potential and reduce mitochondrial mass through mitophagy, which shows that mitochondria work more efficiently. This improved metabolic efficiency explains why nad+ benefits for weight management go beyond just burning calories to fundamental changes in how cells process and use fat.
NAD+ and energy production in mitochondria
Mitochondria, known as the cell's powerhouse, depend on NAD+ weight loss mechanisms at their biochemical core. NAD+ levels in these energy-producing organelles are 2-4 times higher than in other parts of the cell. This concentration difference shows why mitochondrial NAD+ dynamics play a vital role in metabolic health.
NAD+ in oxidative phosphorylation
The connection between nad+ and cellular energy production ends in oxidative phosphorylation—the process that creates most of our body's ATP. NAD+ works as an electron carrier that accepts hydride equivalents to form NADH. This NADH then delivers electrons to the mitochondrial electron transport chain (ETC). The process starts when NADH connects with Complex I (NADH:ubiquinone oxidoreductase) of the ETC.
The electron transfer from NADH through Complex I releases energy that pushes four hydrogen ions into the intermembrane space. These protons then flow back into the mitochondrial matrix through ATP synthase. This drives ATP production through chemiosmotic coupling. This elegant system turns chemical energy from nutrients into about 30-32 ATP molecules—far more efficient than the 2 ATP from glycolysis alone.
We can see how vital this system is by exploring genetic mutations that affect Complex I. These defects can cause MELAS syndrome (mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes), which shows the significance of nad+ benefits in energy metabolism.
Maintaining mitochondrial health
Nad weight loss effects are closely linked to mitochondrial integrity and function. Of course, mitochondrial NAD+ levels directly affect how these organelles handle stress and maintain peak performance. Mitochondrial function gets worse when NAD+ levels drop due to age or metabolic stress.
Lower NAD+ affects mitochondrial sirtuins—especially SIRT3, the main mitochondrial deacetylase. Less sirtuin activity leads to hyperacetylation of mitochondrial proteins. This compromises their function and boosts reactive oxygen species (ROS) production. Adequate NAD+ levels help prevent oxidative damage and keep mitochondria working efficiently.
Research shows that NAD+ precursor supplements can fix many aspects of mitochondrial dysfunction. Nicotinamide riboside (NR) treatment substantially improved mitochondrial structure in diabetic mice and reduced severely damaged mitochondria. Nicotinamide mononucleotide (NMN) also fixed mitochondrial dysfunction after ischemic events by reducing mitochondrial fragmentation.
NAD+ and mitochondrial biogenesis
Making new mitochondria—mitochondrial biogenesis—is another significant nad+ to nadh relationship that affects energy metabolism. NAD+ levels influence this process through sirtuin activation, particularly SIRT1, which deacetylates and activates PGC-1α (peroxisome proliferator-activated receptor gamma coactivator 1-alpha).
PGC-1α, the key regulator of mitochondrial biogenesis, arranges the expression of many genes needed to create new mitochondria. These include nuclear respiratory factor 1 (NRF1) and mitochondrial transcription factor A (TFAM), which are essential to coordinate mitochondrial component production.
Research backs up these mechanisms. NR supplements increased the mitochondrial DNA/nuclear DNA ratio in diabetic mouse kidneys, showing enhanced mitochondrial biogenesis. NR treatment also boosted PGC-1α, NRF1, and TFAM expression. This shows why understanding what is nad+ matters so much for creating new energy-producing organelles.
NAD+ supplements also boost the expression of mitochondrial carriers encoded by solute carrier family (SLC) genes. These genes help shuttle various metabolites across the inner mitochondrial membrane. Better nutrient transport helps optimize mitochondrial function and energy production capacity.
Factors that deplete NAD+ levels
Image Source: Restoration Healthcare
The benefits of NAD+ weight loss depend on keeping enough of this vital molecule in our bodies. NAD+ plays a key role in metabolism, but several factors drain its availability and reduce its impact on metabolic health. You need to know what depletes NAD+ to understand why maintaining healthy levels gets harder as time passes.
Aging and chronic inflammation
NAD+ levels drop substantially in various tissues as we age, affecting both humans and rodents. This reduction is a telltale sign of physical decline that leads to many age-related diseases. Two connected mechanisms cause this drop: our bodies make less NAD+ and use more of it.
NAMPT (nicotinamide phosphoribosyltransferase), which controls NAD+ production, decreases in white adipose tissue and skeletal muscle as we get older. Long-term low-grade inflammation, also known as "inflammaging," reduces NAMPT production and makes it harder for the body to create enough NAD+.
Aging tissues accumulate more DNA damage, which keeps PARPs (poly-ADP-ribose polymerases) constantly active. This ongoing activation pulls NAD+ away from helpful metabolic pathways and speeds up aging.
Overnutrition and metabolic stress
What we eat affects how well our bodies convert nad+ to nadh. Eating too much—especially foods high in fat and protein—reduces NAD+ production. Cells try to protect themselves when there are too many nutrients, but long-term overfeeding can permanently damage them.
We need enough NAD+ to burn fat properly in our mitochondria. When mice consume too many lipid calories, their liver NAD+ levels drop and cause lipotoxicity. Lower NAD+ bioavailability leads to metabolic problems in aging mice, humans, and rodents with type 2 diabetes.
This metabolic stress affects many types of tissue. NAD+ levels in the liver decrease with age in both humans and rodents, which might explain why older individuals are more likely to develop non-alcoholic fatty liver disease (NAFLD). Problems with NAD+-controlled sirtuin signaling also play a vital role in developing insulin resistance and type 2 diabetes.
Enzymes that consume NAD+ (PARPs, CD38)
Sirtuins, PARPs, and NAD+ glycohydrolases like CD38 are three enzyme classes that use NAD+. PARPs and CD38 stand out as the biggest consumers that can quickly drain cellular NAD+ pools.
PARP1 uses large amounts of NAD+ during DNA repair and normal cell function. It binds NAD+ more strongly and works faster than SIRT1, with a lower Km (20-97 μM) and higher Vmax. When activated, PARPs split NAD+ into NAM (nicotinamide) and ADP-ribose, adding the latter as polymers to various proteins.
CD38 is the biggest NAD+ consumer. This multifunctional ectoenzyme works as both a glycohydrolase and ADP-ribosyl cyclase. It's very inefficient—using almost 100 NAD+ molecules to create one cyclic ADP-ribose. CD38 levels rise with age, which reduces NAD+ and impairs mitochondrial function.
CD38 breaks down both NAD+ and its precursors like nicotinamide mononucleotide (NMN) and nicotinamide riboside (NR). This affects how well these supplements work in the body. Pro-inflammatory cytokines like TNFα increase CD38 production. This creates a cycle where inflammation triggers more CD38, leading to less NAD+ and worse metabolic problems.
How to boost NAD+ naturally
Natural lifestyle changes can boost your NAD+ weight loss results. Your body knows how to produce and maintain optimal NAD+ levels. Studies show that daily habits can affect cellular NAD+ by a lot. This improves your metabolism and energy production without supplements.
Exercise and caloric restriction
Exercise remains one of the best ways to naturally increase NAD+ levels. Your body produces more NAD+ when you exercise regularly. We noticed that exercise increases the AMP/ATP ratio in cells. This gets more NAD+ production and thus encourages more availability. Young and older people who do aerobic and resistance training show higher NAMPT levels—the rate-limiting enzyme in NAD+ production.
Different exercises give you unique benefits:
-
Moderate aerobic activity (running, cycling, swimming) makes cells metabolically active
-
High-intensity interval training (HIIT) boosts mitochondrial activity
-
Resistance training helps you keep muscle mass and stay metabolically healthy
Caloric restriction and intermittent fasting can boost your NAD+ levels. Research reveals that eating fewer calories helps increase NAD+ availability. This happens when an enzyme converts nicotinamide into NAD+. Caloric restriction improves the NAD+/NADH ratio—often by a lot more than just increasing total NAD+ levels.
Sleep and circadian rhythm
Quality sleep is vital to maintain healthy NAD+ levels. NAD+ levels follow a 24-hour rhythm that changes based on when you eat and sleep. Light affects NAMPT activity—it decreases with light and increases in darkness—which directly affects NAD+ production.
Bad sleep throws off NAD+ metabolism and speeds up its decline. Your health improves when you follow your natural circadian rhythm, and your body uses NAD+ better. Regular sleep schedules help optimize natural NAD+ cycling.
Reducing NAD+ consumption
You can preserve NAD+ levels by preventing excessive breakdown. Chronic inflammation uses up NAD+ faster, so anti-inflammatory strategies matter. Anti-inflammatory foods (berries, fatty fish, leafy greens) help maintain NAD+ levels. Processed foods and excess sugar should be avoided.
Your liver needs NAD+ to break down alcohol. Each drink reduces your NAD+ levels by a lot. Moderate drinking helps maintain metabolic health.
Stress reduction helps your body use NAD+ properly. Mindfulness meditation, progressive muscle relaxation, and breathing exercises minimize cortisol release. High cortisol negatively affects metabolic processes that depend on NAD+.
NAD+ precursors and supplements
NAD+ precursors are a great way to get your NAD+ levels up when natural methods don't cut it. Your body can turn these building blocks into NAD+, which might help with NAD+ weight loss by making your metabolism work better.
Nicotinamide riboside (NR)
NR boosts NAD+ levels by a lot in your liver, muscle, and other tissues. It works differently from other precursors because it doesn't trigger GPR109A receptors, which means you won't get side effects like flushing. Research shows NR kicks SIRT1 and SIRT3 into action. This helps your oxidative metabolism and shields you from getting obese from your diet.
People who took 500mg of NR twice a day saw their NAD+ levels jump about 60% in their blood cells. The original tests showed this dose might help your heart work better, but scientists need to do more research. Most people handle up to 2000mg of NR daily just fine, with few side effects.
Nicotinamide mononucleotide (NMN)
NMN pulls double duty as an NAD+ precursor and a key messenger molecule in your body. Your body quickly changes NMN into NAD+, which powers up your cells. Tests show taking 600-900mg daily can multiply your blood NAD+ levels five to six times.
A two-month study showed something interesting. People taking 600mg or 900mg NMN could walk about 1.5 times farther in six minutes. NMN stays good in water for 7-10 days and keeps 93-99% of its strength.
Nicotinic acid and nicotinamide
These older forms of vitamin B3 were the original NAD+ precursors. Nicotinic acid (NA) uses the Preiss-Handler pathway and bumps up NAD+ in skin cells even when NAMPT isn't working.
Nicotinamide (NAM) can block sirtuin activity if you take too much, which might limit how well it works. Notwithstanding that, both these compounds help protect cells from dying off.
Safety and dosage considerations
NR stays safe up to 2000mg daily, while NMN has proven safe at 1200mg daily for two months. Side effects are usually mild - maybe some nausea, tiredness, or headaches.
The quickest way to get results is to take NR at 500-1000mg daily. NMN works best between 250-900mg daily, with 600mg hitting the sweet spot between how well it works and what it costs.
What science says: human studies and trials
Image Source: Cell & Bioscience - BioMed Central
Clinical research on NAD+ weight loss shows both encouraging and mixed results in humans. Animal studies give strong evidence, but human research needs more work.
Effects on energy and metabolism
Studies show that NAD+ precursor supplements can safely raise NAD+ levels by 40-60% when people take FDA-approved doses (300mg/day). Higher doses might even double these levels in blood cells. The results of a 6-week NR study caught researchers off guard when 1000mg daily lowered systolic blood pressure and made arteries less stiff in middle-aged and older adults. A shorter 3-week trial with NR supplements showed older males had fewer inflammatory markers—which could help metabolism.
Recent studies point to better mitochondrial health markers. Patients with heart failure showed better mitochondrial breathing in their blood cells when they took NAD+ precursors. Blood NAD+ levels went up, but muscle improvements remained small.
NAD+ and weight loss outcomes
A newer study published as a meta-analysis reveals that NAD+ precursor supplements led to a small drop in BMI (-0.19 kg/m²) and higher adiponectin levels (1.59 μg/mL) compared to control groups. Scientists haven't seen any big changes in overall body weight yet.
One crossover trial used NR supplements (1000mg/day for 6 weeks) and found interesting results. Body fat dropped by 4%, while fat-free mass grew by 2%. People's sleeping metabolic rate improved by 4%, though insulin sensitivity stayed the same.
Limitations and future research
These human studies have problems. Most use small groups of 40 or fewer people. They don't stick to the same doses, and study lengths bounce between 1-20 weeks. Without doubt, some trials need better control groups, which makes it hard to draw firm conclusions.
Nobody has done a largest longitudinal study about artificially raising NAD+ levels. This gap raises some potential risks. Each person's response varies greatly—some see dramatic benefits while others barely notice a change.
Scientists need to break down the best doses, figure out when to take them, and find out who might get the most from NAD+ improvements.
Conclusion
NAD+ is the life-blood of metabolic health and weight management. This piece explores how this vital coenzyme drives cellular energy production through glycolysis, the TCA cycle, and oxidative phosphorylation. NAD+ also activates key sirtuin proteins that control fat metabolism. This makes it crucial for anyone looking to improve their body composition.
Your body's NAD+ levels drop with age, which explains why weight management becomes harder over time. The good news is that you can naturally boost NAD+ through regular exercise, eating less, quality sleep, and lower inflammation. You also have the option to supplement with precursors like nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN) to restore your NAD+ levels.
Studies on NAD+ supplements for weight management show mixed results, but the basic science behind it makes sense. Research shows better mitochondrial function, metabolic flexibility, and cellular energy production when NAD+ levels go up. This means working with NAD+ tackles the root cause rather than just treating symptoms.
Understanding NAD+ and metabolism gives us great insights into our body's energy regulation at the molecular level. While it's not a miracle cure for weight issues, healthy NAD+ levels are fundamental to good metabolism. Scientists will likely discover more ways to use NAD+ in metabolic health of all types. Right now, your best bet is to combine lifestyle changes with targeted supplements to maintain optimal NAD+ levels and support lifelong metabolic health.
