Some wellness clinics and longevity influencers promote NAD+ as reversing cellular damage, slowing or reversing aging, improving brain health and even helping with hangover recovery, but evidence is lacking. It is typically sold as a dietary supplement and as an injectable or IV treatment created by compounding pharmacies. The excitement and use of NAD-related treatments came from promising results in studies involving mice. “Giving supplements that generate NAD production in mice has multiple organ system benefits, including longevity,” said Dr. Samuel Klein, professor of medicine and nutritional science at WashU Medicine in St. Louis. “The hitch is that this has not been translated into humans.” Klein is conducting research related to NAD and its potential benefits.
