NAD Level Test — At-Home NAD⁺ & NADH Blood Spot Test UK
Understand your NAD⁺
a key molecule behind cellular energy
Understand your NAD⁺ — a key molecule behind cellular energy. NAD⁺ (nicotinamide adenine dinucleotide) and its partner NADH are coenzymes your cells use for energy production, DNA repair and healthy cellular function, and research shows NAD⁺ levels tend to decline with age. This simple at-home finger-prick test measures both NAD⁺ and NADH, so you can understand your baseline and track it over time.

What you’ll learn
-
Your current NAD⁺ and NADH levels
-
Your redox (NAD⁺/NADH) balance — a snapshot of cellular energy status
-
How your levels relate to age and metabolism
-
A baseline you can retest to see how your levels change over time
How it works
1. Order online — kit posted discreetly.
2. Collect at home — a quick finger-prick, placing a few drops of blood on the collection card.
3. Let the sample dry, then post it to the lab in the prepaid packaging.
4. Get your personalised report in ~7 working days. What it measures: your NAD⁺ and NADH levels are measured from a dried blood spot sample. These coenzymes are central to how your cells produce energy and repair themselves, and NAD⁺ levels tend to decline naturally as we get older.
[About NAD⁺ and your results] NAD⁺ and NADH levels vary from person to person, and NAD⁺ naturally declines with age. Many people test to establish a baseline and then see how factors like exercise, sleep, diet or NAD⁺ precursor supplements affect their levels over time. It's worth being clear: NAD testing is an informational wellbeing tool, not a medical diagnosis, and there is no single "correct" number. If you'd like help interpreting your result, consider discussing it with a knowledgeable healthcare professional.
[FAQ]
Q: What are NAD⁺ and NADH?
A: They're the oxidised (NAD⁺) and reduced (NADH) forms of a coenzyme found in every cell, essential for energy production, DNA repair and cellular signalling. NAD⁺ levels tend to fall with age.
Q: Is this a medical or diagnostic test?
A: No. It's a wellbeing test that measures a biomarker; it doesn't diagnose, treat, cure or prevent any disease.
Q: How is the sample taken?
A: A simple finger-prick at home — a few drops of blood on a collection card, which you post to the lab.
Q: Is this ISO 15189-accredited like your cancer tests?
A: The NAD kit is CE-IVD marked and made to EN ISO 13485, and analysed to recognised EU quality standards. It's a wellbeing biomarker test rather than a diagnostic screening test
Q: Can I use it to track supplements or lifestyle changes?
A: Yes — many people retest to see how their levels change over time. Results are for wellbeing insight, not medical advice.
Q: How much does it cost and how fast are results?
A: £249, results in ~7 working days.
