What Is NAD+ (Nicotinamide Adenine Dinucleotide)?

NAD+ stands for Nicotinamide Adenine Dinucleotide. It’s a natural molecule found in every cell in the human body. NAD+ plays a vital role in turning food into energy and helps keep our cells healthy [1]. It’s especially important for energy production, repairing DNA, and supporting brain and muscle function.

Why is NAD+ important?

NAD+ is essential for several key processes in the body [2][3], including:

Energy production – helps convert food into energy inside your cells
Cell repair – supports DNA repair and protects cells from damage
Brain function – supports focus, clarity, and mental energy
Muscle health – plays a role in muscle strength and recovery
Healthy ageing – helps regulate processes linked to ageing and longevity

What happens when NAD+ levels drop?

As we get older, the levels of NAD+ in our bodies naturally decrease. This drop may be linked to:

Feeling more tired or low in energy
Slower recovery after exercise
Age-related memory or focus issues
Weaker immune function
Visible signs of ageing (e.g. skin changes)

Scientists believe that maintaining or boosting NAD+ levels could help support healthy ageing and improve energy and wellbeing.

How can NAD+ levels be boosted?

There are several ways people try to support their NAD+ levels, including:

Supplements – such as nicotinamide riboside (NR) or nicotinamide mononucleotide (NMN), which are precursors to NAD+
NAD+ infusions or injections – delivered by a healthcare professional for faster absorption
Healthy lifestyle habits – such as regular exercise, good sleep, and intermittent fasting, which may help support natural NAD+ production

Are NAD+ supplements safe?

Research is ongoing, but NAD+ precursors and therapies are generally considered safe when used as directed. However, it’s always best to speak to a healthcare professional before starting any new supplement or treatment, especially if you have a medical condition or take other medications.

Is NAD+ used in medical treatments?

In clinical settings, NAD+ therapies are being explored for various health goals, including:

Supporting recovery from chronic fatigue or burnout
Improving focus and mental clarity
Supporting muscle repair and performance
Promoting healthy ageing and longevity

These treatments are usually given under medical supervision and may involve high-purity NAD+ delivered by injection or infusion.

Key Takeaways

NAD+ is a natural molecule found in all cells, essential for energy, repair, and brain function.
Levels of NAD+ decrease with age, which may affect energy and overall wellbeing.
Boosting NAD+ through supplements, injections, or lifestyle habits may support health and healthy ageing.
Scientific interest in NAD+ is growing, but more research is still needed.
Always speak to a healthcare professional before starting NAD+ therapies or supplements.

Reminder: NAD+ plays a central role in keeping your body energised and functioning well. Supporting your NAD+ levels may be part of a broader approach to long-term health, but it’s important to get advice from a qualified professional.
