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?

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.

Does NAD+ Help With Sleep?

NAD+ is linked to your circadian rhythm through sirtuin proteins that help regulate your internal body clock, so healthy NAD+ levels may support more consistent sleep — but timing matters, since taking it too close to bedtime can feel energising for some people.

The NAD+-Circadian Rhythm Connection

NAD+ levels naturally rise and fall across a roughly 24-hour cycle, synced to your body's internal clock. NAD+ activates sirtuin proteins, particularly SIRT1, which help control the genes that regulate this internal timing. When NAD+ availability drops, this regulatory system can become less precise, which has been associated with disrupted sleep-wake patterns in research.

Why Timing Affects Sleep

Because NAD+ supplementation can have an energising effect for some people, taking it too close to bedtime may work against a good night's sleep rather than support it. This is one of the reasons morning dosing is generally recommended — see our full breakdown in Best Time to Take NAD+: Morning or Night?.

What This Means for At-Home Users

If you're building NAD+ into a daily or weekly routine, pay attention to how you personally respond. Some people notice no effect on sleep at all; others find that dosing earlier in the day helps them avoid feeling wired at night. There's no single right answer — it comes down to your own experience.

Frequently Asked Questions

Can NAD+ keep me awake at night?

For some people, yes — NAD+ can have an energising effect that makes evening dosing feel counterproductive. Morning dosing is generally the safer default.

Does low NAD+ cause insomnia?

Disrupted NAD+ activity has been associated with sleep-wake pattern disruption in research, though sleep problems have many possible causes and NAD+ is only one contributing factor among many.

Is there a best time to take NAD+ for sleep support?

Most guidance points to morning or early daytime dosing, working with your body's natural NAD+ rhythm rather than against it.

Will NAD+ replace good sleep hygiene?

No. Consistent sleep schedules, reduced evening screen time, and a dark, cool bedroom remain the foundation of good sleep — NAD+ isn't a substitute for the basics.
