Buy NAD Test Kit: Guide

The Longevity NAD Level Test Kit measures intracellular NAD+ levels using a dried blood spot collection card. This method captures NAD+ concentration within your cells — a more accurate reflection of cellular energy status than plasma-based tests. Results are processed by a certified laboratory and returned within 10–12 days of mailing your sample.

Results are typically available 10–12 days after you mail your sample. The kit ships within the USA via USPS Ground Advantage (2–5 days) or Priority Mail/FedEx (1–3 days). Be sure to follow all collection instructions carefully — failure to do so may require a replacement kit at an additional $50 fee.

Anyone experiencing fatigue, brain fog, or signs of accelerated aging may benefit. Athletes optimizing performance, individuals managing metabolic or neurodegenerative conditions, and longevity enthusiasts tracking the impact of supplements like NMN, NR, or resveratrol are all ideal candidates for periodic NAD+ level monitoring.
