What is NAD+, and why do people use it?

NAD+ is a coenzyme found in every cell. It helps your body produce energy, support metabolism, and carry out DNA repair. NAD+ levels naturally decline with age, which is why some people use NAD+ supplements as part of a wellness routine.

What do NAD+ supplements support?

People use NAD+ supplements to support cellular energy, cognitive function, metabolism, and healthy ageing. Results vary, and research is ongoing.

How can you verify that your My NAD product is genuine?

Each genuine My NAD product includes a unique authenticity verification system. You can verify your product through the official authenticity portal to confirm it is genuine.

Why is product authentication important for supplements?

Counterfeit supplements may contain incorrect ingredients, improper dosages, or poor-quality materials. Verifying authenticity helps ensure you receive a genuine product that meets quality and safety standards.

Who should consider taking NAD+ supplements?

Adults interested in supporting healthy aging, energy metabolism, cellular health, and overall wellness may consider NAD+ supplements. Always consult a healthcare professional before starting any new supplement.

Are NAD+ supplements generally well tolerated?

NAD+ supplements are generally well tolerated when you use them as directed. If you are pregnant, breastfeeding, taking medication, or managing a medical condition, you should speak with a healthcare professional before use.

Why do NAD+ levels decline with age?

Research indicates that NAD+ levels naturally decrease as we age due to changes in cellular metabolism and increased demand for DNA repair processes. This decline has led to growing interest in NAD+ supplementation.

How may My NAD products fit into a healthy aging routine?

NAD+ supports cellular energy production and DNA repair. You may use My NAD products as part of a broader routine that includes good nutrition, exercise, sleep, and regular medical guidance. Results vary from person to person.

Where can I buy genuine My NAD products in the UK?

To ensure authenticity and quality, purchase My NAD products only through the official My NAD website or authorized distributors.

How to Boost NAD+ Levels Naturally: Food, Exercise & Lifestyle Tips

Regular exercise, a diet rich in vitamin B3 and tryptophan, time-restricted eating, consistent sleep, and moderating alcohol intake are the main lifestyle levers linked to supporting your body's own NAD+ production — all before considering supplementation.

Exercise

Physical activity — particularly high-intensity interval training combined with strength and aerobic work — stimulates the NAMPT enzyme responsible for recycling NAD+ in the body. Regular movement is one of the most consistently cited natural levers for supporting NAD+ levels.

Nutrition: Foods That Support NAD+

Foods rich in vitamin B3 (turkey, fish, mushrooms), tryptophan (eggs, nuts, chicken), and polyphenols (blueberries, red grapes, dark chocolate) provide raw materials and protective compounds that support your body's NAD+ metabolism.

Fasting & Meal Timing

Time-restricted eating patterns — such as eating within an 8-hour window — activate AMPK, a cellular energy sensor linked to a healthier NAD+/NADH balance. This doesn't require extreme fasting; even modest changes to your eating window may help.

Sleep and Circadian Alignment

NAD+ levels rise and fall with your circadian rhythm, so consistent sleep timing and morning light exposure support your body's natural NAD+ cycle. See our related post on the best time to take NAD+ for more on how timing interacts with supplementation specifically.

Temperature Therapies

Sauna sessions and brief cold exposure (like cold showers) are both associated with activating cellular stress-response pathways that may support NAD+ production, though the evidence here is still developing.

Alcohol and Sun Exposure

Your body uses NAD+ to metabolise alcohol, so reducing intake helps preserve existing levels. Similarly, UV exposure has been linked to NAD+ depletion in skin cells, which is one more reason sun protection matters.

Frequently Asked Questions

What's the single best way to boost NAD+ naturally?

There isn't one silver bullet — exercise, diet, sleep, and fasting all contribute modestly. Combining several habits is more effective than relying on just one.

Can diet alone raise NAD+ as much as supplementation?

Diet and lifestyle support your body's own NAD+ production, but they work more gradually than direct supplementation. Many people use both approaches together.

Does intermittent fasting really affect NAD+?

Time-restricted eating activates AMPK, a pathway linked to a healthier NAD+/NADH ratio, though individual responses vary.

Is cold exposure necessary, or is sauna enough?

Neither is necessary — both are optional additions some people use alongside the more established basics like exercise, diet, and sleep.

Does alcohol really deplete NAD+?

Yes — your body uses NAD+ as part of how it metabolises alcohol, so regular or heavy drinking can place additional demand on your NAD+ supply.
