What is NMN?
NMN (nicotinamide mononucleotide) is a naturally occurring molecule found in living cells. It is a direct precursor your body can use to makeNAD+(nicotinamide adenine dinucleotide), a coenzyme that powers cellular energy metabolism and day-to-day maintenance. WhenNAD+is in short supply, cells may struggle to keep up with everyday demands.NAD+naturally declines by about 1% every year, so even with a healthy diet and active lifestyle,NAD+might not keep up with daily demands.
The Roles of NAD+
Energy Metabolism
NAD+participates in the reactions that turn food into ATP inside mitochondria. It also supports the electron transport chain, which fuels nearly every cellular function.
DNA Access & Repair Signaling
NAD+is consumed by PARP enzymes involved in the cellular response to everyday DNA stressors. SustainingNAD+helps ensure these maintenance pathways have the coenzyme they need.
Sirtuin Activity
Sirtuins rely onNAD+to influence cellular housekeeping, metabolic signaling, and chromatin regulation—factors tied to how cells adapt to stress and maintain efficiency.
Mitochondrial Function
NAD+availability supports pathways that help mitochondria produce energy efficiently and manage oxidative workload.
NAD+ boosters like NMN and NR are only the beginning.
After years of analyzing the research, we've aligned with a systems-level approach to address four main pathways to support healthy NAD+ levels throughout the entire body. This systems-level approach is described elegantly by Nichola Conlon and Dianne Ford in a recent study on NAD+ restoration.
Every Renue By Science formula helps you maximize NAD+ through one of these pathways.

Why do NAD+ levels change with age?
NAD+ tends to decline with age. Three common contributors:
- Higher demand. Everyday stressors can increase the activity of NAD+-consuming enzymes (such as PARPs and CD38), drawing down available pools.
- Lower recycling efficiency. The body’s salvage pathway, which recycles precursors like NMN and NR, may not keep pace as well over time.
- Oxidative load and inflammatory tone. Ongoing cellular housekeeping can further increase NAD+ use.
These shifts can show up as lower day-to-day energy, slower recovery from routine exertion, and less metabolic flexibility. If you feel like your thoughts have slowed down and you can’t make it through a workout, your NAD+ levels might be behind it.
Why NMN belongs in your daily routine.
- Support steady energy metabolism by feeding mitochondrial pathways.
- Support DNA maintenance signaling, which relies on NAD+.
- Support sirtuin-linked longevity pathways involved in cellular housekeeping.
Together with sleep, protein intake, movement, and sunlight, NMN offers a science-grounded way to support healthy aging from the cellular level up.

Supports DNA Maintenance & Cellular Health
Sirtuins rely onNAD+to influence cellular housekeeping, metabolic signaling, and chromatin regulation—factors tied to how cells adapt to stress and maintain efficiency.
Supports Vascular & Endothelial Function
NAD+availability supports pathways that help mitochondria produce energy efficiently and manage oxidative workload.
Supports Metabolic Flexibility
Sustaining healthyNAD+helps the cellular machinery that coordinates how we use and switch among fuel sources from food.
Why NMN is helpful for healthy aging.
Aging involves cumulative cellular work: oxidative load, DNA maintenance, and changing inflammatory tone, all of which increase demand forNAD+. When supply lags behind demand, cells may struggle to keep pace. Damage can accumulate and cells may struggle between repair and normal daily functions.
How to use Pure NMN powder.
- New to NMN: start with about half a scoop (~250 mg) once daily for one week
- Then: consider 1 full scoop (500 mg) once daily, or continue with half a scoop based on preference and tolerance
- Timing: Choose a consistent time each day. Morning is ideal to align with circadian NAD+ rhythms.
What to expect from Pure NMN powder?
People use NMN to support day-to-day energy metabolism and to help maintain NAD+ status with age. Some notice changes sooner, others later. Effects and timing vary.
Best results come from consistent use alongside adequate protein, sleep, movement, and a generally healthy routine.
Lifestyle factors can slow the drain of NAD+, and NMN can amplify the benefits of a strong routine by supporting ATP production, mitochondrial efficiency, and NAD+-dependent maintenance pathways so your cells perform reliably day to day at every age.
