| Description | Precursor of NAD⁺, a coenzyme that declines with age and is required by sirtuins and PARPs. Human trials are small and short; long-term effects are unknown. | NAD⁺ precursor with the most human safety data in its class. Reliably raises blood NAD⁺; clinical benefits in humans are not yet established. |
| Timing note | Usually taken in the morning to align with the body's daily NAD⁺ rhythm (a hypothesis, not proven). | Usually taken in the morning, like NMN. |

Common product or study range — not a personal recommendation. Upper limits are ceilings, not targets.
If you take both
No need to take both — they feed the same pathway, and the pair hasn't been studied.
Pick one. On its own, NR has more published human safety data.
