Aging &amp; Longevity

With the most accurate measurements to date, researchers show that whole-brain NAD+ levels decline with age in healthy subjects, confirming previous studies of smaller brain regions. 


Scientists discover how to measure measure NAD+ across the entire human brain. 

Argentinian scientists prevent hearing loss in mice via the supplementation of phytosterols — cholesterol-like molecules found in plants. 

The chemical structure of a phytosterol called β-sitosterol is depicted next to a man trying to hear something.

Discover groundbreaking research revealing the potential of plant-derived phytosterols to prevent hearing loss. Explore the study's findings and their implications at NAD.com.
