I. Core physiological functions
1. Participation in energy metabolism
When sugars, fats, and proteins are broken down for energy, NAD⁺ receives hydrogen and is converted into NADH, which is then used in mitochondria to generate ATP (cellular energy).
Without NAD⁺, cells cannot produce energy and will lose their activity directly.
2. Activate the longevity protein Sirtuins
The Sirtuins family proteins must rely on NAD⁺ to be activated:
- Repair damaged DNA
- Regulate cellular aging and slow down cellular aging
- Improve mitochondrial function and reduce oxidative stress
- Regulate inflammation and maintain metabolic homeostasis
3. DNA Damage Repair
PARP (a DNA repair enzyme) works highly dependent on NAD⁺.
When cells are exposed to radiation or oxidative stress and suffer DNA damage, PARP consumes NAD⁺ to repair the genes; when NAD⁺ is insufficient, the damage accumulates, accelerating aging and increasing the risk of diseases.
4. Regulating apoptosis and maintaining cellular homeostasis
Balancing cell survival and programmed cell death, eliminating damaged and senescent cells; maintaining the normal cell cycle.
5. Immune and Inflammation Regulation
It participates in the energy supply of immune cells and regulates inflammatory factors; low NAD⁺ is prone to cause chronic low-level inflammation (aging-related inflammation).
6. Neurological protection
- Supports the energy supply of neurons
- Maintains synaptic functions, improves cognitive and memory-related mechanisms
