NAD Blood Test

Measure your NAD levels

The new Blood Test is an easy, at-home kit that helps you check your NAD+ and NADH levels – key molecules involved in energy and cellular health. By knowing your baseline levels, you can make informed and safe decisions about lifestyle choices or supplementation, tailored to your body’s needs.

The kit uses advanced technology to provide accurate results from a small blood sample. Results are simple to understand and allow you to monitor your NAD status safely over time, helping you maintain your wellbeing.

What are NAD and NADH?

NAD (Nicotinamide Adenine Dinucleotide) is a vital molecule naturally produced in the body. It plays a key role in converting food into energy, supporting cellular repair, and maintaining overall metabolic balance. NAD declines as we age, so maintaining healthy levels is crucial for overall health, longevity and slowing ‘signs of aging’.

NAD supplements have recently become highly popular in the UK – to immediately boost NAD levels – helping to promote overall energy, mental clarity and signs of vitality.

NADH is the reduced form of NAD and works alongside to help regulate energy production and cellular functions. Together, NAD and NADH are crucial for maintaining cellular health, ensuring your cells have the energy to function efficiently and repair damage over time.

Why take the NAD Blood Test?

NAD levels differ widely between individuals depending on factors such as:

• Age
• Diet
• Lifestyle choices
• Underlying health conditions.

Testing your NAD provides an accurate baseline, helping to determine whether supplementation or lifestyle changes are appropriate for you. Sustaining healthy NAD levels is vital to ensure you only take on what your body needs.

Extremely low NAD+: May result from chronic illness, poor diet, or mitochondrial dysfunction; medical evaluation recommended.

Extremely high NAD+: Often caused by excessive supplementation; can disrupt metabolic balance and may lead to vascular inflammation.

Extremely low NADH: Could indicate either efficient energy production or severely depleted NAD levels due to vitamin B3 deficiency or mitochondrial dysfunction.

Extremely high NADH: Commonly linked to mitochondrial dysfunction or over-supplementation.

What will the NAD Blood Test tell me?

• Your NAD+ and NADH levels.
  The test measures both NAD+ (the oxidized form) and NADH (the reduced form) in your blood showing how much energy your cells are producing vs how much they are repairing and regenerating.

• Your NAD+/NADH ratio
  This ratio reflects your cellular redox balance, which is essential for metabolism, energy production, and overall cell function. A healthy ratio indicates that your body is efficiently converting nutrients into energy and supporting cell repair.

Normal ranges:
NAD+ (µM) Low - 20 | High - 36
NADH (µM) Low - 0.6| High - 1.8
NAD+/NADH ratio Low - 16.3 | High - 45

Results are not a diagnosis. If your values are outside the healthy reference range, consult a qualified healthcare professional for interpretation and any necessary follow-up.

How does the blood test work?

The test uses a small sample of your blood, which is processed using NADMED Technology to accurately measure NAD and NADH concentrations. Results provide a clear picture of your cellular energy balance, helping identify potential deficiencies or imbalances. This information can then guide personalised supplementation or lifestyle adjustments.

Simply book your blood test at home or in-clinic, and receive your results within 7 working days of the sample being received at the laboratory.
