NAD+

1. Cell respiration: generate ATP for energy supply.

2. Mitochondrial function: regulating balance and promoting biosynthesis.

3. Activate PARP: Responsible for DNA repair.

4. Genomic stability: protection against genetic mutations and cancer.

Step 5 Activate Sirtuins: regulate metabolism and delay aging.

6. Cellular stress: Helps cells resist damage.

7. Neural cell function: support cognitive activity.

8. Protect nerve cells: prevent neurodegenerative diseases.

9. Fat metabolism: regulate fat synthesis, decomposition and oxidation, and promote energy balance.

10. Glucose metabolism: regulate glycogen synthesis, decomposition and glucose oxidation, and coordinate energy metabolism.
