The Cellular Energy Currency
Nicotinamide Adenine Dinucleotide (NAD+) is a vital coenzyme found in every living cell. It is essential for mitochondrial energy generation and cell survival pathways.
The Decline of NAD+ and Aging
As we age, systemic NAD+ levels decline by roughly 50% every 20 years:
- Sirtuin Regulation: NAD+ acts as the mandatory fuel source for sirtuins—a family of proteins that regulate cellular health, manage DNA repair, and mitigate inflammation.
- Mitochondrial Decay: Declining NAD+ leads to mitochondrial decay, resulting in reduced cognitive stamina and accelerated aging.
