Let’s start on your health journey with NAD+.
What is NAD+?
Nicotinamide adenine dinucleotide (NAD+) is a vital living cell coenzyme with many roles. It controls energy metabolism, gene expression, DNA repair, and stress response.
That’s not all. Scientists are studying NAD+ for its potential to treat:
- aging
- cancer
- progressive brain damage
- metabolic disorders
The coenzyme plays a critical role in the following biological functions:
Energy production
NAD+ is essential in cellular respiration, helping mitochondria convert nutrients into usable energy. Mitochondria are cell power plants that make energy (ATP) your body needs to function.
Mitochondria need the right amount and balance of NAD+ and NADH to function. NAD+ (oxidized) and NADH (reduced) are two forms of NAD. They’re vital molecules that help cells make energy through a redox reaction, when:
- NAD+ accepts electrons (reduced) and becomes NADH
- NADH donates electrons (oxidized) and becomes NAD+
Cell health and DNA repair
The NAD+ and NADH balance is vital to how well cells work and stay healthy. An imbalance can lead to faster aging or make you illness-prone.
As we age, our DNA degenerates due to wear and tear, sunlight, and pollution. NAD+ supports specialized proteins called sirtuins and PARPs.
These enzymes repair DNA and impact immune cell function and gene expression. These processes restore balance, helping tissues stay healthy, and may contribute to longevity.
Neurological health
NAD+ is crucial for brain health because it:
- Supports your brain’s ability to form new connections and adapt (neuroplasticity)
- Protects brain cells from damaging conditions
- Maintains healthy thinking, memory, and other mental functions
- Assists brain cells to communicate
- Helps with brain repair and renewal
The brain can’t function properly without enough NAD+ against aging and environmental challenges.
Scientists suggest that NAD+ can protect against Alzheimer’s, Parkinson’s, and ALS.
Controlling stress effects
NAD+ controls inflammation, helping the body fight infections and cellular stress. Enough NAD+ improves immunity, helping you recover from illness faster.
Reducing chronic inflammation lowers the risk of many age-related health issues. The coenzyme’s anti-inflammatory properties may speed up muscle recovery.
Why is NAD+ Important?
A vital concern is that NAD+ levels decline with age. This phenomenon can lead to reduced energy production and weakened cellular repair processes. People are more prone to age-related diseases.
Lower NAD+ levels also impact the following:
Aging and longevity
NAD+ is vital for cellular repair and keeping your genes stable and working properly. When NAD+ levels decline, age-related issues show up.
You may lose muscle strength, flexibility, and endurance. It’s harder to stay active. You might feel weaker, tire more easily, and notice a drop in physical performance. Reduced balance, coordination, and stability increase the risk of accidents.
Health issues linked to aging include cardiovascular disease, hypertension, and heart failure. The elderly are also susceptible to:
- High cholesterol
- Arthritis
- Obesity
- Diabetes.
- Chronic kidney disease
- Depression
- Alzheimer’s disease and dementia
Researchers believe that optimal NAD+ levels may support healthy aging and cellular function. This effect may increase the number of years a person remains healthy and active.
Mitochondrial function and energy production
Mitochondria rely on NAD+ to produce ATP. Their ability to generate energy is essential for cellular function and health.
Low NAD+ levels can slow down metabolism. This can lead to weight gain, difficulty losing weight, and insulin resistance.
Supporting NAD+ levels may help sustain energy production, boost cellular efficiency, and improve endurance.
Cognitive health
NAD+ helps your brain cells produce energy to function properly. Increased production can lead to better focus, memory, and mental clarity. Improved brain cell communication is essential for learning, memory, and mood regulation.
NAD+ also helps protect brain cells from damage and inflammation. This vital function may prevent cognitive decline and neurodegenerative diseases.
A decline in NAD+ levels can cause problems with memory, focus, and mental sharpness. There’s also a higher risk of Alzheimer’s and dementia.
Physical health and muscle function
NAD+ boosts energy production and reduces oxidative stress, which achieves the following:
- Reduced inflammation
- Improved endurance
- Increased muscle strength
- Faster post-exercise recovery
- Less muscle soreness
Enough NAD+ enables muscle tissue repair, leading to better training adaptation.

How to maintain healthy NAD+ levels
It’s vital to have enough NAD+ in the body for cells to function well. Lifestyle and nutrition can control NAD+ levels. These include caloric restriction, fasting, physical activity, and keeping glucose availability low.
A healthy lifestyle can help people live long, free of major chronic diseases.
Diet
The following nutrients can support NAD+ production:
- Vitamin B3 (niacin)
- Tryptophan
- Nicotinamide mononucleotide (NMN)
- Nicotinamide riboside (NR)
Eat fish, mushrooms, green vegetables, and dairy to restore NAD+ levels.
Caloric restriction
Research shows a significant increase in lifespan by reducing calories by 25–60%. This approach raises NAD+ levels, activates sirtuins, and lowers NADH.
Eating habits
When and what we eat affects NAD+ levels in our cells. Too much fatty or sugary food causes energy overload in our cells and reduces NAD+. Large amounts of fats and carbohydrates also lessen NAD+.
Avoid large portions of unhealthy food as it can upset your energy balance and cause cell damage.
Exercise
Aerobic activities like running, cycling, or swimming can boost NAD+ levels. Exercise stimulates NAMPT, an enzyme that helps recycle and produce more NAD+.
Regular exercise can slow down or even reverse NAD+ levels decline. Activating the NAD+ salvage pathway helps the body reuse building blocks to make more NAD+.
Get regular sleep
NAD+ levels naturally rise and fall over a 24-hour cycle. Sleep deprivation or irregular sleep disrupts NAD+ production.
Poor sleep also lowers NAMPT activity. The essential enzyme helps make NAD+. The reduced function causes sleep problems and health decline.
To support healthy NAD+ levels, keep to a regular sleep schedule. Avoid excessive light at night, as it can interfere with NAD+ production.
NAD+ supplementation
Supplementing with NAD+ precursors can help increase NAD+. Two of the most researched options include:
- Nicotinamide Riboside (NR) – Taking NR can increase NAD+ levels and support cellular health.
- Nicotinamide Mononucleotide (NMN) – How much NAD+ your body makes depends on NMN levels.
NMN and NR are relatively new but studies show they don’t trigger side effects. Early research, including animal studies, suggests that NAD+ supplementation is generally well-tolerated.
More clinical trials are necessary to establish its long-term effects in humans.
