NAD+ Hype Outpaces Science: What You Need to Know
11 May
Summary
- NAD+ levels decline with age, potentially linked to age-related diseases.
- Animal studies show promise, but human evidence for NAD+ benefits is still developing.
- Many NAD+ products lack rigorous scientific backing and vary in quality.
The compound nicotinamide adenine dinucleotide (NAD+) is at the center of intense interest within the wellness and longevity sectors, fueling a booming market for supplements and therapies.
While NAD+ is crucial for energy production and DNA repair within cells, and its natural decline with age is associated with age-related diseases, researchers emphasize that human studies are still in their nascent phases. Animal models have demonstrated significant benefits, but these results have not yet been consistently replicated in humans.
Many NAD+ products available commercially, such as oral supplements and IV infusions, are not supported by extensive clinical trials. Scientists note that the molecule itself is poorly absorbed when taken orally, and while precursors like NR and NMN show promise and appear safe, their widespread efficacy is yet to be definitively established.
Concerns also exist regarding the quality and accuracy of products on the market, with independent testing revealing variability. Despite the preliminary nature of much of the research, the allure of NAD+ continues to drive significant consumer interest and investment.
