Episode description
- Nicotinamide adenine dinucleotide (NAD+) is central to cellular energy and mitochondrial health, driving redox reactions that produce ATP. Declining levels are linked to metabolic disorders, sarcopenia, and diabetes
- Alzheimer's disease has strongly associated with disrupted NAD+ balance, and research suggests restoring intake can reverse cognitive decline rather than merely slowing disease progression
- Animal studies show restoring NAD+ fully reversed advanced Alzheimer's features, including memory loss, inflammation, tau pathology, oxidative stress, and DNA damage, even after severe disease was established
- NAD+ functions as an upstream regulator of brain resilience, coordinating energy production, DNA repair, inflammation control, and protein processing, reframing Alzheimer's as a systems-level energy failure
- Practical strategies emphasize testing NAD+ status and supporting production safely via niacinamide alongside adequate intake of other B vitamins
