NAD⁺ (nicotinamide adenine dinucleotide) is a natural molecule found in every cell of your body and is essential for life itself. It acts as a coenzyme — a helper molecule that allows enzymes to carry out the countless chemical reactions needed to keep you healthy and energised.

NAD⁺ exists in two main forms: NAD⁺, the active (oxidised) form, and NADH, the reduced form. These two forms continuously convert back and forth within your cells, driving essential processes like energy production, DNA repair, and cellular renewal. Together, they help convert the food you eat into usable energy, support brain function, and promote healthy ageing.

As we get older — or when we’re under stress, lacking sleep, or not eating well — our NAD⁺ levels naturally decline. This gradual reduction can affect how energised, focused, and resilient we feel day to day. Maintaining healthy NAD⁺ levels is thought to help support your body’s natural ability to produce energy, repair cells, and function at its best.

By supporting your body’s NAD⁺ balance through good nutrition, regular exercise, quality sleep, and (where appropriate) targeted supplementation, you may help your cells work more efficiently — keeping you feeling more energised, clear-headed, and ready to take on the day..

NAD⁺ acts like a “helper molecule” in your cells, supporting key processes such as:

Energy production – converting food into usable energy
DNA repair – helping protect your cells from everyday damage
Cognitive support – assisting with focus, concentration, and brain function
Healthy ageing – supporting your body’s natural repair and renewal processes

NAD⁺ supplements and related products are not intended to diagnose, treat, cure, or prevent any disease or medical condition.

Always consult a healthcare professional before starting any new supplement, especially if you are pregnant, breastfeeding, or taking medication.

Do not exceed the recommended daily dose, and keep all supplements out of the reach of children. Supplements are designed to support, not replace, a varied diet and healthy lifestyle.

If you experience any unwanted effects, stop use immediately and seek urgent medical advice.
