Intracellular NAD Level Testing

Common symptoms associated with low NAD+ levels include persistent fatigue, brain fog, reduced muscle strength and endurance, slower recovery from exercise, and signs of accelerated aging. Low NAD+ has also been linked to metabolic disorders and neurodegenerative conditions such as Alzheimer's disease.

Intracellular NAD+ testing measures the amount of nicotinamide adenine dinucleotide present inside your cells using a blood-based collection method. This provides a direct snapshot of cellular energy metabolism and helps assess overall cellular health, aging markers, and the impact of lifestyle or supplement interventions.

At-home NAD+ test kits use a dried blood spot collection method analyzed in a laboratory setting, offering an accurate, blood-based measurement of intracellular NAD+ levels. Accuracy depends on properly following collection instructions; incorrect collection can void results and require a replacement kit.

After mailing your collection card back to the lab, test results are typically available within 10-12 days. You will receive personalized data on your intracellular NAD+ levels, which is best reviewed alongside a healthcare professional for proper interpretation and guidance.

Yes, periodic NAD+ testing is commonly used to monitor the effectiveness of NAD+ boosting supplements such as NMN, NR, resveratrol, or spermidine. Testing before and after a supplementation period helps quantify changes in cellular NAD+ levels and informs adjustments to your wellness strategy.

If the dried blood spot collection card instructions aren't followed correctly, the sample may be unusable and the test voided. In this case, a replacement kit fee of $50 applies. It's important to carefully follow the printed instructions included with every kit to ensure valid results.
