Nicotinamide adenine dinucleotide, more commonly referred to as NAD+, is an essential coenzyme found in all living cells. It plays a pivotal role in energy production, DNA repair, and overall cellular health. Without adequate NAD+ levels, our bodies struggle to perform vital functions – a problem that becomes more apparent as we age. If you have been looking for ways to increase your energy, support healthy ageing, or simply optimise your health, discovering how to boost NAD+ levels naturally can make a substantial difference. We will explore scientifically backed strategies to help you enhance your NAD+ levels and experience the benefits of improved well-being.

What is NAD+ and Why Is It Important

Before diving into natural strategies to increase NAD+, it is crucial to understand why this coenzyme is so essential. NAD+ is vital for numerous biochemical reactions, including:

1. Energy Production: NAD+ is heavily involved in the mitochondrial processes that convert nutrients into ATP (adenosine triphosphate), the primary molecule of energy in your cells.

2. DNA Repair: NAD+ supports enzymes known as sirtuins and PARPs (poly ADP-ribose polymerases). Sirtuins regulate gene expression related to longevity, while PARPs repair damaged DNA.

3. Cellular Defence: NAD+ works as a helper molecule that shuttles electrons during redox reactions, helping to maintain the redox balance in cells.

4. Healthy Ageing: According to research, declining NAD+ levels are associated with age-related illnesses and metabolic issues.

As we get older, our bodies naturally produce less NAD+. Lifestyle factors such as stress, poor diet, and lack of exercise can further drain our NAD+ reserves. Fortunately, there are ways to boost NAD+ levels naturally, which in turn can help improve energy, support normal metabolic function, and slow down aspects of cellular ageing.

1. Embrace a NAD+-Friendly Diet

A. Increase Niacin-Rich Foods

NAD+ is synthesised in part from vitamin B3, which is also known as niacin or nicotinamide. Foods rich in vitamin B3 can provide the raw materials for your body to produce more NAD+. Examples include:

• Lean meats (chicken, turkey)

• Fish (salmon, tuna)

• Whole grains (brown rice, whole wheat bread)

• Legumes (lentils, beans)

• Seeds (sunflower seeds)

Not only do these foods supply niacin, but they often contain other nutrients that support overall health, including essential amino acids and healthy fats.

B. Include Tryptophan Sources

Tryptophan, an essential amino acid, can be converted into NAD+ through the kynurenine pathway. Rich sources of tryptophan include:

• Poultry (chicken, turkey)

• Eggs

• Cheese

• Nuts (almonds, peanuts)

• Pumpkin seeds

Research suggests that a diet including adequate amounts of tryptophan may support the body’s efforts to sustain NAD+ levels naturally.

C. Consider Polyphenol-Rich Foods

Polyphenols such as resveratrol have been associated with activating sirtuins, which, in turn, use NAD+ to carry out beneficial actions in our cells. Resveratrol can be found in foods like red grapes, blueberries, raspberries, and certain nuts. Although resveratrol does not directly increase NAD+ levels, it promotes sirtuin activity, making the best use of the NAD+ available and potentially helping the body regulate its usage more efficiently.

2. Exercise and Physical Activity

Engaging in regular physical activity is not just good for cardiovascular health and weight management; it can also help to maintain and potentially boost NAD+ levels. According to studies , exercise helps stimulate enzymes that rely on NAD+, such as sirtuins, and it may encourage the cells to produce more mitochondria, thereby supporting an environment that benefits from higher NAD+ availability.

A. Aerobic Exercise

Cardiovascular exercises, including running, cycling, swimming, and brisk walking, have been shown to encourage your cells to become more metabolically active. When your cells demand more energy, the body responds by enhancing processes that involve NAD+.

B. Resistance Training

Weightlifting and other forms of resistance training can also contribute to healthy ageing by promoting muscle mass retention and metabolic health. Increased muscle mass supports a higher metabolic rate and may lead to improved NAD+ utilisation.

C. Make It Sustainable

To see the best outcomes, choose an exercise routine that you can consistently maintain. The benefits of exercise on NAD+ levels build over time, so regularity is more important than intensity. Aim for at least 150 minutes of moderate exercise or 75 minutes of vigorous exercise each week, per standard guidelines.

3. Embrace Intermittent Fasting or Time-Restricted Eating

Intermittent fasting and time-restricted eating patterns have garnered a lot of attention for their potential benefits on longevity, weight management, and cellular health. These eating patterns might also help to support higher levels of NAD+. Research suggests that fasting triggers cellular stress responses, activating sirtuins that consume NAD+ to initiate cellular repair mechanisms. In turn, the body often ramps up NAD+ production to meet the increased demand.

A. Common Methods

1. 16:8 Approach: Fast for 16 hours each day, then consume all meals within an 8-hour window.

2. 5:2 Diet: Eat normally for five days a week and restrict calorie intake (roughly 500–600 calories) on the other two days.

3. 24-Hour Fast: Fast for one full day once or twice a week.

B. Practical Tips

• Start gradually if you are new to fasting.

• Stay well-hydrated during fasting periods.

• Avoid heavily processed or sugary foods when breaking your fast to optimise benefits.

If you have any underlying health conditions, always consult a doctor before beginning any fasting regimen.

4. Get Adequate Sleep and Reduce Stress

Sleep is often underestimated for its role in overall health, including the maintenance of NAD+ levels. Chronic sleep deprivation can upset metabolic processes and may contribute to a dip in your body’s natural NAD+ production. Good-quality sleep has been shown to regulate hormones and maintain energy homeostasis, which supports a stable environment for NAD+ usage and replenishment.

A. Improve Sleep Hygiene

• Stick to a regular sleep schedule (going to bed and waking up at the same time every day).

• Limit exposure to screens before bedtime as blue light can disrupt melatonin secretion.

• Keep your bedroom dark, cool, and quiet to promote more restful sleep.

B. Manage Stress

High levels of psychological stress trigger the release of cortisol, which can negatively influence metabolic processes that rely on NAD+. Stress reduction techniques such as mindfulness meditation, progressive muscle relaxation, yoga, and breathing exercises can improve overall well-being while helping conserve and appropriately use NAD+.

5. Consider Natural Supplements and Nutraceuticals

While diet and lifestyle changes are foundational for boosting NAD+ naturally, certain supplements can provide additional support. It is always best to consult with a doctor before starting any supplement regimen, especially if you have underlying conditions or are on medication.

A. Nicotinamide Riboside (NR)

Nicotinamide riboside, a form of vitamin B3, has been studied for its role in increasing NAD+ levels in humans. NR is believed to be well-tolerated and effective at elevating NAD+ levels. It converts directly to NAD+ through a unique salvage pathway.

B. Nicotinamide Mononucleotide (NMN)

Nicotinamide mononucleotide, commonly abbreviated NMN, is another precursor to NAD+. Research suggests that it can be efficiently taken up by cells and converted into NAD+. Early trials have shown promise for potential benefits in metabolic and age-related decline.

C. Resveratrol

While resveratrol is not a direct precursor to NAD+, it is often included in NAD+-supporting regimens because of its potential ability to activate sirtuins. These enzymes utilise NAD+ in their functions, including DNA repair and gene regulation. Resveratrol is found naturally in red grapes, red wine, and certain berries.

D. Quercetin

Quercetin, a bioflavonoid present in onions, apples, and several other fruits and vegetables, is known for its antioxidant properties and potential to promote healthy ageing. Some studies suggest quercetin may help maintain cellular health, supporting the efficiency of processes that rely on NAD+.

6. Prioritise Mitochondrial Health

Since NAD+ is closely tied to mitochondrial function, protecting and supporting your mitochondria can, in turn, preserve healthy NAD+ levels. Mitochondria are the powerhouses of your cells, producing energy and playing roles in signalling pathways.

A. Avoid Toxins and Pollutants

Exposure to air pollution, tobacco smoke, and other toxins can harm mitochondrial function. Reducing exposure by avoiding smoking areas and minimising use of harsh household chemicals can potentially support better mitochondrial and NAD+ health.

B. Antioxidant-Rich Foods

Oxidative stress can damage mitochondria, so keeping a diet rich in antioxidants – such as vitamin C, vitamin E, and phytonutrients found in brightly coloured fruits and vegetables – may help protect cells from oxidative damage, ensuring a healthier environment for NAD+ processes.

7. Stay Hydrated and Maintain Electrolyte Balance

Although hydration might not be the first thing that comes to mind when thinking about NAD+, being properly hydrated helps maintain the fluid balance necessary for nearly all metabolic processes in the body. Electrolytes like magnesium, potassium, and sodium are vital for nerve function, muscle function, and the biochemical balance in cells. This ensures that the enzymatic reactions that depend on NAD+ are not hindered by an imbalance in fluid or ionic concentrations.

8. Maintain a Healthy Body Weight

Being overweight or obese can stress your metabolism, leading to insulin resistance, chronic low-grade inflammation, and disruptions in important cellular processes. These imbalances may contribute to an accelerated decline in NAD+ levels. Studies indicate that maintaining a healthy weight through balanced eating and consistent exercise can help ensure your body’s energy systems function optimally, thus supporting stable NAD+ levels.

A. Adopt Balanced, Whole-Foods Eating

Focus on nutrient-dense foods such as lean proteins, fruits, vegetables, whole grains, and healthy fats. Avoid excessive sugar, refined grains, and saturated or trans fats.

B. Monitor Portion Sizes

Even when eating healthy, portion control is crucial. Overeating, even nutrient-dense foods, can lead to an increased calorie intake and eventual weight gain.

C. Combine Diet and Exercise

A balanced diet alongside regular physical activity creates a synergistic effect for both healthy weight management and NAD+ maintenance.

9. Limit Alcohol Intake

Alcohol consumption, especially in larger quantities, can negatively affect liver health, where a significant portion of NAD+ recycling and production occurs. Chronic alcohol use depletes NAD+ levels, which can hamper important metabolic processes. While moderate alcohol consumption might not have dramatic impacts on NAD+ levels, limiting intake or opting for low-alcohol beverages may help preserve higher NAD+ status.

10. Explore Emerging Therapies with Caution

There is growing interest in advanced interventions, such as NAD+ IV infusions, for boosting NAD+ levels. While anecdotal reports and some early studies suggest benefits, these therapies can be costly and are not always backed by long-term safety data. If you are intrigued by more direct methods of NAD+ therapy, consult a qualified medical professional who can advise you on the potential risks and benefits based on the latest clinical research.

Balancing Lifestyle for Sustainable NAD+ Optimisation

Boosting NAD+ levels is less about one “magic bullet” and more about creating a holistic lifestyle that supports cellular health. The good news is that many strategies to increase NAD+ – such as improved diet, regular exercise, better sleep, stress management, and responsible supplementation – also contribute to overall well-being. By consistently making these healthy choices, you can give your body what it needs to naturally elevate NAD+ over time.
