NAD+ Index Test

NAD+ (nicotinamide adenine dinucleotide) is a vital coenzyme that fuels mitochondrial energy, supports DNA repair, and plays a key role in healthy aging. But as we age — or face chronic stress, poor sleep, illness, or alcohol exposure — NAD⁺ levels naturally decline. This can lead to fatigue, brain fog, slower recovery, and reduced cellular performance.

Our NAD+ Index Test is an advanced at-home blood test that uses a dried blood spot (DBS) sample to measure a comprehensive panel of biomarkers in the NAD+ pathway. These include:

• NAD+ – your primary energy coenzyme

• NADH – the reduced form involved in ATP production

• NADPH & NADP – key markers of antioxidant function and biosynthesis

• Nicotinamide (NAM) & Nicotinic Acid (NA) – vitamin B3 metabolism markers

• NAD+:NADH and NADP:NADPH ratios – indicators of mitochondrial and redox health

• NAD+/NADP Index – a reflection of B3 sufficiency and metabolic status

Whether you’re supporting longevity, using NAD+ precursors (like NMN or NR), or managing recovery and energy, this test gives you clear, actionable insights into your cellular health.
