How To Increase NMN Naturally

As we get older, it is common to notice changes in energy, focus, recovery, and overall health. Many people feel more tired than they used to, take longer to recover after exercise, or struggle with weight gain and poor sleep. These changes are not just “part of getting older” — they are linked to real changes happening inside our cells.

One of the key changes is a drop in a molecule called NAD (nicotinamide adenine dinucleotide). NAD is essential for how our cells make energy and repair damage. Research shows that NAD levels can fall by 30–50% by middle age, and continue to decline as we get older. This drop affects how well our cells work, especially in organs like muscles, the brain, and the heart.

This is why people are now talking so much about NMN and NAD. NMN helps the body make more NAD, which may support energy, metabolism, and healthy ageing. Interest in NMN has grown quickly because it targets one of the root causes of age-related decline, rather than just treating symptoms.

You can explore NMN-based products in the NMN supplements collection,  which focuses on supporting NAD levels as part of a healthy ageing approach.

Dr Eric Verdin, President of the Buck Institute for Research on Aging, explains it clearly:

“NAD is essential for cell health. When NAD levels fall, cells lose their ability to make energy and repair themselves properly.”

What Is NAD?

NAD is a molecule found in every living cell. Its main job is to help cells turn food into energy. Without enough NAD, cells cannot produce energy efficiently, which can lead to fatigue, poor muscle function, and slower recovery.

NAD also helps repair damaged DNA and supports proteins called sirtuins, which are linked to healthy ageing and stress resistance. Every time your body repairs DNA or responds to stress, NAD is used up. This means your body needs a steady supply to stay healthy.

As we age, NAD levels naturally decline. This happens faster in people who experience long-term stress, poor sleep, obesity, inflammation, or high alcohol intake. Lower NAD levels are linked to reduced energy, weaker muscles, insulin resistance, and slower cell repair.

According to research published in human and animal studies, NAD levels can drop by nearly half by the time people reach their 40s or 50s, depending on lifestyle and health.

What Is NMN?

NMN (nicotinamide mononucleotide) is a natural compound that your body uses to make NAD. In simple terms, NMN is a building block for NAD.

When you take NMN or produce it naturally, your body converts it into NAD inside your cells. This is why NMN is often described as being “one step away” from NAD. Because of this close link, NMN is seen as one of the most effective ways to support NAD levels.

Human studies have shown that NMN supplementation can raise NAD levels in the blood, which confirms that the body can use NMN effectively. Some studies have also found improvements in insulin sensitivity and muscle function, especially in older adults.

Dr Shin-ichiro Imai, a leading NAD researcher at Washington University School of Medicine, has said:

“NMN is a key molecule that helps maintain NAD levels, which are critical for metabolic health and ageing.”

For a detailed explanation of how NMN works in the body, see How NMN works.

You can also read about the benefits and safety of NMN in NMN benefits, side effects, and dosage.

Is NMN the Same as Vitamin B3?

NMN is not the same as vitamin B3, but they are connected.

Vitamin B3 (also called niacin) is found in foods like meat, fish, nuts, and grains. Your body can use vitamin B3 to make NAD, but this process takes several steps and becomes less efficient as you get older.

NMN and NR (nicotinamide riboside) are more direct forms. NR must first be changed into NMN, and then NMN is turned into NAD. This means NMN is closer to NAD than vitamin B3 or NR.

Because of this, NMN may work more efficiently in older adults, whose ability to convert nutrients into NAD has slowed down. This is one reason NMN has become popular in healthy ageing research.

A clear comparison of these pathways is explained in NMN vs NR vs NAD.

How Your Body Makes NMN Naturally

How Does the Body Produce NMN?

Your body makes NMN naturally every day as part of a recycling system inside your cells. This system is called the NAD salvage pathway. In simple terms, your body takes used NAD, breaks it down into smaller parts, and then rebuilds it again. NMN is one of the key steps in this rebuilding process.

Inside your cells, a special enzyme helps turn an old form of NAD into NMN, and then NMN is quickly changed back into fresh NAD. This process allows your cells to keep making energy and repairing damage without needing a constant supply from food.

When you are young and healthy, this recycling system works very well. However, research shows that this process slows down as we age. By middle age, the body’s ability to recycle NAD efficiently can drop by 30–50%, depending on lifestyle and health. This means less NMN is made, and NAD levels fall as a result.

Dr Shin-ichiro Imai, Professor of Developmental Biology at Washington University School of Medicine, explains:

“The body relies on NMN to maintain NAD levels. As we age, the system that produces NMN becomes less active, which contributes to age-related decline.”

This is why scientists are interested in ways to support NMN production, either naturally or through supplements. A deeper explanation of this process is covered in How NMN works.

What Causes NMN and NAD Levels to Drop?

Ageing is the main reason NMN and NAD levels fall, but it is not the only cause. Several everyday factors can speed up this decline.

Long-term stress increases hormones like cortisol, which puts extra strain on your cells and uses up more NAD. Chronic inflammation, often linked to poor diet or illness, also increases NAD use because the body is constantly repairing damage.

Alcohol is one of the biggest drains on NAD. Each time your body breaks down alcohol, it uses large amounts of NAD, leaving less available for energy and repair. Poor sleep disrupts your body clock, which normally helps control NAD levels across the day. Over time, lack of sleep can lower NAD even further.

These factors together explain why some people experience faster ageing at a cellular level than others, even at the same age. This topic is explored in more detail in Why I stopped taking NMN.

Foods That Contain NMN Naturally

Yes, NMN is found naturally in some foods, mainly plant-based foods. However, the amounts are very small compared to what is used in research studies or supplements.

NMN in food is measured in micrograms, while NMN supplements usually contain hundreds of milligrams. This means you cannot raise NMN levels significantly through food alone, but NMN-rich foods can still support overall cell health.

Dr Eric Verdin, President of the Buck Institute for Research on Aging, notes:

“Diet alone is unlikely to restore NAD levels in older adults, but healthy foods can support the pathways that keep NAD working properly.”

Top 8 Foods That Contain NMN and Why They Matter

Here are some of the foods with the highest known NMN content, along with why they are still useful for healthy ageing:

1. Edamame (young soybeans) – One of the highest natural sources of NMN; also rich in plant protein and fibre.

2. Broccoli – Contains small amounts of NMN and powerful antioxidants that protect cells.

3. Cabbage – Supports gut health and provides vitamins that help reduce inflammation.

4. Avocado – Low NMN content, but rich in healthy fats that support mitochondria.

5. Tomatoes – Provide antioxidants like lycopene, which help protect ageing cells.

6. Cucumbers – Small NMN content and high water content to support hydration.

7. Mushrooms – Support immune health and provide B vitamins linked to energy metabolism.

8. Raw beef (very small amounts) – Contains traces of NMN and important minerals like iron and zinc.

Although these foods contain NMN, the amounts are too low to raise NAD levels on their own. This is why many people combine a healthy diet with other strategies discussed in
How to increase NMN naturally.

What Foods Have the Most NMN?

When ranked by NMN content alone, plant foods tend to come out on top. Edamame and broccoli consistently rank highest, followed by cabbage and cucumber. Animal foods contain much smaller amounts.

Even the highest NMN foods provide less than 1 mg per serving, while studies often use 250–1,000 mg per day. This gap explains why food supports NMN indirectly rather than acting as a replacement.

Why NMN-Rich Foods Are Still Healthy

Even though NMN levels in food are low, these foods are still very important for healthy ageing. They contain other nutrients that help your body use NAD more efficiently and reduce how quickly it is used up.

These nutrients include antioxidants, fibre, vitamins, and minerals that lower inflammation and protect mitochondria (your cells’ power plants). In this way, NMN-rich foods help protect the NAD you already have, even if they do not raise levels directly.

For people interested in stronger NAD support, supplements are often used alongside lifestyle changes. These options are discussed in the NMN supplements collection and the wider anti-aging and longevity collection.

Best Diet Choices to Support NAD Levels

What Is a NAD-Friendly Diet?

A NAD-friendly diet is not about eating one special food. Instead, it focuses on foods that help your body protect NAD and make it more efficiently. Diet supports NAD indirectly, by reducing inflammation, supporting energy metabolism, and lowering stress on your cells.

When you eat a balanced diet with enough protein, vegetables, and healthy fats, your body wastes less NAD on damage control. This means more NAD is available for energy, repair, and healthy ageing.

Dr Eric Verdin, President of the Buck Institute for Research on Aging, explains it simply:

“Lifestyle and diet do not replace NAD, but they reduce how quickly it is used up.”

This is why diet works best when combined with other habits like sleep and exercise, rather than on its own.

Which Foods Are High in Vitamin B3?

Vitamin B3, also called niacin, is important because your body can use it to make NAD. Niacin is one of the basic building blocks your cells rely on, especially when NMN production slows with age.

Foods high in vitamin B3 include chicken, turkey, tuna, salmon, peanuts, mushrooms, and whole grains. These foods help provide the raw materials your body needs to keep NAD levels stable.

Research shows that low vitamin B3 intake is linked to fatigue and poor energy metabolism. However, niacin is less efficient than NMN because it takes several steps for the body to turn it into NAD. This is why diet alone often cannot fully restore NAD in older adults.

For people who want stronger support, this difference is explained in
NMN vs NR vs NAD.

Which Foods Contain Tryptophan?

Tryptophan is an amino acid found in protein-rich foods. Your body can use tryptophan to help make NAD through a longer pathway, especially when other sources are low.

Foods rich in tryptophan include eggs, dairy products, turkey, chicken, oats, seeds, and nuts. While this pathway exists, it is slow and inefficient, especially as we age. This means tryptophan supports NAD production, but it is not a fast or powerful method on its own.

Doctors generally view tryptophan as a supporting nutrient, not a primary solution for low NAD.

Which Foods Contain Polyphenols Like Resveratrol?

Polyphenols are natural compounds found in plants. They do not increase NAD directly, but they help your body use NAD more efficiently.

Resveratrol, found in grapes, berries, and red wine, is one of the best-known polyphenols. It activates proteins called sirtuins, which rely on NAD to do their job. This means polyphenols increase the demand for NAD rather than the supply.

This relationship is explained in
NMN vs resveratrol.

Eating foods rich in polyphenols can support healthy ageing, but without enough NAD, their benefits may be limited.

Does Cooking Affect NMN in Food?

How Cooking Changes NMN Levels

NMN is sensitive to heat, light, and storage time. When foods are cooked at high temperatures or stored for long periods, small amounts of NMN and related nutrients can be lost.

Boiling vegetables for long periods causes more nutrient loss than steaming or light cooking. Freezing and reheating can also reduce delicate compounds.

That said, most of the NMN in food is already very small, so cooking does not make a large practical difference to NMN intake. Cooking mainly affects other nutrients that help protect NAD, such as antioxidants and vitamins.

Is Raw or Cooked Food Better for NMN?

There is no need to eat everything raw. Some foods are healthier cooked, as cooking improves digestion and nutrient absorption. Others are fine raw.

A simple approach is to eat a mix of raw and cooked vegetables, avoid overcooking, and focus on overall diet quality rather than chasing tiny NMN differences.

Lifestyle Habits That Increase NAD Naturally

How Exercise Affects NAD Levels

Exercise is one of the strongest natural ways to support NAD. When you move your body, your cells need more energy, which activates pathways that use and recycle NAD more efficiently.

Studies show that regular exercise increases enzymes involved in NAD production and helps slow the age-related decline in NAD levels.

Dr Shin-ichiro Imai, Professor at Washington University School of Medicine, has said:

“Exercise is one of the most effective ways to maintain healthy NAD metabolism.”

Is Cardio Good for NAD?

Yes. Activities like walking, running, cycling, and swimming increase mitochondrial activity and improve how your body handles energy. This supports better NAD recycling.

Even brisk walking for 30 minutes most days has been shown to improve metabolic health linked to NAD function.

Does Strength Training Increase NAD?

Strength training also supports NAD by building muscle. Muscle tissue uses large amounts of energy and plays a key role in glucose control and ageing.

As we age, muscle loss speeds up NAD decline. Strength training helps slow this process and supports healthier metabolism.

How Much Exercise Do You Need?

You do not need extreme exercise. Most health guidelines suggest:

• At least 150 minutes of moderate exercise per week

• Strength training 2 times per week

Consistency matters more than intensity. Regular movement supports NAD far more effectively than short bursts of intense exercise followed by long periods of inactivity.

Can Fasting Increase NAD Levels?

How Fasting Affects NMN and NAD

Fasting means taking planned breaks from eating. During these breaks, your body switches from using food for energy to using stored fuel. This change activates repair systems inside your cells, many of which depend on NAD.

When you fast, your body increases the activity of proteins called sirtuins. These proteins help with cell repair and stress resistance, but they only work when enough NAD is available. This is why fasting is often linked to better NAD recycling rather than a direct increase in NMN itself.

Research in humans and animals shows that short periods of fasting can increase enzymes involved in NAD production and slow down how quickly NAD is used up. This helps explain why fasting is often discussed alongside longevity and metabolic health.

Dr Mark Mattson, a neuroscientist and former Chief of the Laboratory of Neurosciences at the US National Institute on Aging, explains:

“Intermittent fasting activates cellular stress-response pathways that improve mitochondrial function and increase resistance to ageing-related disease.”

Fasting works best when combined with other habits such as exercise and good sleep, rather than used on its own.

What Are the Most Common Fasting Methods?

There are several fasting styles people commonly use:

• 16:8 fasting, where you eat within an 8-hour window and fast for 16 hours

• 5:2 fasting, where you eat normally five days a week and reduce calories on two days

• Occasional 24-hour fasts, done once a week or less

For most people, 16:8 fasting is the easiest to maintain and provides many of the benefits without extreme restriction.

Who Should Avoid Fasting?

Fasting is not suitable for everyone. People who are pregnant, breastfeeding, underweight, or have a history of eating disorders should avoid fasting. Those with diabetes, low blood sugar issues, or chronic medical conditions should speak to a healthcare professional first.

If fasting feels stressful or leads to poor sleep, it may do more harm than good. In these cases, focusing on sleep, diet quality, and exercise is often more effective for supporting NAD.

How Sleep and Stress Affect NAD Levels

Why Sleep Is Important for NAD

Sleep plays a major role in controlling circadian rhythm, which is your body’s internal clock. NAD levels naturally rise and fall across the day, following this rhythm. When sleep is poor or irregular, this rhythm is disrupted, and NAD production becomes less efficient.

Studies show that people who sleep fewer than 6 hours per night have worse metabolic health and higher inflammation, both of which increase NAD use. Over time, this can lower NAD levels further.

Good sleep helps your body repair DNA, reset hormone levels, and recycle NAD more effectively.

How Stress Lowers NAD Levels

Stress increases the release of cortisol, a hormone that prepares your body for danger. While useful in short bursts, long-term stress keeps your cells in a constant state of alert. This increases inflammation and DNA damage, both of which use up NAD.

Chronic stress is linked to faster ageing at a cellular level. People experiencing burnout often report fatigue, brain fog, and poor recovery — all signs linked to low NAD activity.

Dr Elissa Epel, Professor of Psychiatry at the University of California, has said:

“Chronic psychological stress accelerates cellular ageing by increasing inflammation and metabolic strain.”

Managing stress through rest, movement, and routine can help protect NAD levels over time.

Supporting Mitochondrial Health

What Are Mitochondria and Why Do They Matter?

Mitochondria are often called the power plants of your cells. They take nutrients and turn them into energy. NAD is essential for this process. Without enough NAD, mitochondria cannot work properly, leading to low energy and poor cell function.

Healthy mitochondria are linked to better endurance, sharper thinking, and slower ageing.

What Damages Mitochondria?

Several everyday factors damage mitochondria and increase NAD loss. These include smoking, air pollution, excess alcohol, and long-term inflammation. Poor diet and lack of exercise also reduce mitochondrial efficiency.

Over time, damaged mitochondria produce less energy and more waste, which puts further strain on NAD-dependent repair systems.

What Foods Protect Mitochondria?

Foods rich in antioxidants help protect mitochondria from damage. These include colourful fruits and vegetables such as berries, leafy greens, peppers, and tomatoes. Healthy fats from olive oil, nuts, seeds, and oily fish also support mitochondrial membranes.

While these foods do not raise NAD directly, they help reduce oxidative stress, meaning your body uses NAD more efficiently.

Other Factors That Affect NAD Levels

Does Hydration Affect NAD?

Yes. Water and minerals are needed for enzymes to work properly. Even mild dehydration can slow down metabolic reactions, including those involving NAD.

Drinking enough water and maintaining electrolyte balance helps your cells function smoothly and reduces unnecessary stress on NAD pathways.

Does Body Weight Affect NAD Levels?

Excess body fat increases inflammation and insulin resistance, both of which raise NAD demand. Studies show that obesity is linked to lower NAD activity and poorer mitochondrial function.

Losing even 5–10% of body weight can improve metabolic health and reduce NAD strain, especially when combined with exercise.

How Alcohol Affects NAD Levels

Alcohol has one of the strongest effects on NAD. Each time your body breaks down alcohol, it uses large amounts of NAD. Frequent drinking leaves less NAD available for energy and repair.

This is why regular alcohol intake is linked to fatigue, poor sleep, and faster ageing at a cellular level.

For people interested in stronger NAD support beyond lifestyle changes, this topic is explored further in
Can NAD supplements really help with anti-aging?.

Can You Boost NMN Without Supplements?

How Much NMN Do Foods Really Provide?

Foods that contain NMN only provide very small amounts. Most NMN-rich foods contain NMN in micrograms, not milligrams. In comparison, human research studies typically use 250–1,000 mg of NMN per day.

To put this into context, you would need to eat several kilograms of NMN-rich vegetables every day to match the amount used in studies. This is why food alone cannot raise NMN or NAD levels to the same degree seen in research.

Dr Shin-ichiro Imai, a leading NAD researcher at Washington University School of Medicine, explains:

“Diet supports NAD metabolism, but it cannot fully compensate for the age-related decline in NAD production.”

This gap between food intake and research doses is one reason NMN supplements exist.

Why It Gets Harder With Age

As we get older, the body’s ability to make NMN slows down. The enzymes responsible for recycling NMN become less active, and more NAD is used up repairing damage caused by inflammation and stress.

Studies suggest that by middle age, the efficiency of NAD recycling can drop by 30–50%, even in otherwise healthy people. This means the same diet and lifestyle that worked in your 20s may no longer be enough in your 40s or 50s.

This age-related slowdown is one of the main reasons NMN has become an area of interest in healthy ageing research.

When Natural Methods May Be Enough

Natural methods such as a healthy diet, regular exercise, good sleep, and stress management may be enough for younger, healthy individuals.

People under 35–40 years old, with good metabolic health and active lifestyles, often maintain NAD levels well without supplements. For these individuals, focusing on lifestyle habits usually provides the greatest benefit.

When Supplements May Be Helpful

For older adults, or people experiencing fatigue, slow recovery, weight gain, or metabolic issues, natural methods alone may not fully support NAD levels.

In these cases, NMN supplements may help fill the biological gap created by ageing. This is discussed in more detail in the
NMN supplements collection,
which focuses on products designed to support NAD levels as part of a healthy ageing approach.

For a clinical overview of benefits and safety, see
NMN benefits, side effects, and dosage.

What Are NMN Supplements?

Why Do NMN Supplements Exist?

NMN supplements exist because the body’s natural NMN production declines with age, while NAD demand increases. Supplements provide NMN directly, allowing the body to make NAD more efficiently than relying on diet alone.

Dr Eric Verdin, President of the Buck Institute for Research on Aging, has said:

“Boosting NAD levels targets a fundamental process of ageing, rather than a single symptom.”

NMN supplements are not designed to replace healthy habits, but to support the same biological systems that lifestyle changes activate.

NMN vs NR vs NAD Supplements

NMN, NR, and NAD supplements all aim to support NAD levels, but they work differently.

• NMN is one step away from NAD and is converted directly inside cells

• NR must first be converted into NMN before becoming NAD

• NAD supplements are poorly absorbed when taken orally

A simple explanation of these differences is covered in
NMN vs NR vs NAD.

How to Get the Best Results Naturally

Why Diet, Exercise, and Sleep Work Best Together

No single habit can protect NAD on its own. Diet, exercise, and sleep work best when combined because they reduce inflammation, improve energy use, and support NAD recycling at the same time.

Exercise increases NAD demand and recycling, sleep restores circadian rhythm, and diet reduces unnecessary NAD loss. Together, these habits create the best environment for healthy ageing.

This is why experts focus on stacking habits, rather than relying on one solution.

Why There Is No Single Magic Fix

NMN and NAD are part of a complex system. Supplements can help, but they cannot override poor sleep, inactivity, or chronic stress.

Dr Mark Mattson, former Chief of Neurosciences at the US National Institute on Aging, explains:

“Longevity comes from consistent lifestyle patterns, not from one intervention alone.”

What to Expect When Boosting NMN Naturally

NMN Is Not a Stimulant

NMN does not work like caffeine or energy drinks. It does not give an instant boost. Instead, it supports how your cells make energy over time.

Because of this, changes are often subtle and gradual, especially in the first few weeks.

This timeline is explained further in
How long does it take for NMN to work?.

Who Is Most Likely to Benefit

People most likely to benefit from NMN support include:

• Adults over 40

• People with low energy or slow recovery

• Those with metabolic stress or insulin resistance

• Individuals focused on healthy ageing

Younger, very active individuals may notice fewer changes because their NAD levels are already higher.

Common Questions About Boosting NMN Naturally

Can food alone raise NAD levels?

Food can support NAD levels, but it usually cannot raise them significantly on its own, especially as we age. Foods contain only tiny amounts of NMN and related nutrients, while NAD demand increases with age, stress, and inflammation. Diet helps protect NAD, but rarely restores it fully in older adults.

Is fasting better than supplements?

Fasting and supplements do different things. Fasting helps your body recycle and use NAD more efficiently, while supplements provide more raw material to make NAD. For many people, fasting and supplements work best together, not as replacements for each other.

Scientific overview of fasting and cellular repair:
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4516560/

How long does it take to work?

Natural methods like diet, exercise, and sleep usually take weeks to months to show effects. NMN supplements may raise NAD levels within a few weeks, but noticeable changes in energy or recovery are often gradual rather than immediate.

Can you boost NAD too much?

Your body tightly controls NAD levels. With normal lifestyle changes and standard supplement doses, it is very unlikely to raise NAD to harmful levels. Problems are more likely from poor sleep, stress, or excessive alcohol than from too much NAD support.

Is NMN safe long term?

Short-term human studies show NMN is generally well tolerated. Long-term human data is still limited, which is why NMN is best used thoughtfully and alongside healthy lifestyle habits rather than as a shortcut.

Safety review on NAD precursors:
https://pubmed.ncbi.nlm.nih.gov/35674477/

Does stress really lower NAD?

Yes. Long-term stress increases inflammation and DNA damage, both of which use up NAD. Chronic stress is linked to faster cellular ageing and poorer energy metabolism.

Research on stress and cellular ageing:
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6361837/

Is exercise more important than diet?

For NAD health, exercise is often more powerful than diet. Movement directly activates NAD-dependent pathways and improves mitochondrial function. Diet supports this process, but exercise is usually the stronger driver.

Do men and women respond differently?

They can. Hormones influence metabolism, inflammation, and NAD use. Women may notice changes in NAD-related energy and recovery around menopause, while men often see gradual changes with age and muscle loss.

Does menopause affect NAD levels?

Yes. Hormonal changes during menopause can increase inflammation and insulin resistance, which raises NAD demand. This may partly explain why energy and recovery often change during this stage of life.

Can gut health affect NAD?

Yes. Poor gut health increases inflammation, which uses more NAD for repair. A healthy gut helps reduce unnecessary NAD loss, supporting overall metabolic health.

Is NMN better than NR naturally?

NMN and NR both support NAD, but NMN is one step closer in the pathway. Naturally, neither is present in large amounts in food. Differences matter more with supplements than with diet alone.

Scientific comparison of NAD precursors:
https://pubmed.ncbi.nlm.nih.gov/34970985/

Can you test NAD levels?

Testing NAD directly is difficult and not widely available. Some specialised blood tests exist, but they are mainly used in research. Most people track progress through energy, recovery, and metabolic health instead.

Are antioxidants always helpful?

Antioxidants from whole foods are helpful. Very high doses from supplements may sometimes interfere with natural stress signals from exercise. Balance matters more than quantity.

Does sleep timing matter?

Yes. NAD follows your body clock. Late nights, shift work, and irregular sleep disrupt NAD rhythms and reduce repair efficiency. Regular sleep times support healthier NAD cycling.

Can lifestyle changes replace supplements?

For younger, healthy people, lifestyle changes may be enough. For older adults or those with metabolic stress, lifestyle changes often help but may not fully replace the biological support provided by NMN supplements.
