How NMN is Manufactured: Understanding the Production Process
Understanding how NMN is produced both naturally in the body and commercially helps appreciate its value as a supplement. The manufacturing process reflects the compound's sophisticated biological role.
Natural NMN Production in the Human Body
Your body naturally produces NMN through a complex enzymatic process:
- Starting Materials: The process begins with vitamin B3 precursors, particularly nicotinamide
- Key Enzyme: Nicotinamide phosphoribosyltransferase (NAMPT) serves as the primary enzyme
- Chemical Process: NAMPT attaches nicotinamide to 5'-phosphoribosyl-1-pyrophosphate (PRPP)
- Rate Limitation: NAMPT acts as the rate-limiting enzyme, controlling NAD+ production speed
This natural process highlights why NMN supplementation can be beneficial. When NAMPT levels decline with age, NMN production decreases, leading to lower NAD+ concentrations. Supplementing with NMN helps bridge this gap, supporting optimal cellular function.
Alternative NMN Production Pathways
Research has revealed multiple pathways for NMN synthesis:
- From Nicotinamide Riboside (NR): NMN can be produced by adding a phosphate group to NR
- Direct Cellular Entry: Previously, scientists believed NMN had to convert to NR before entering cells
- 2019 Discovery: A dedicated NMN transporter was identified, revolutionizing our understanding
The Game-Changing Discovery of the NMN Transporter
In 2019, researchers made a discovery that transformed our understanding of how NMN works in the body [6]. The identification of the Slc12a8 gene as a specific NMN transporter revealed several crucial insights:
- Direct Absorption: NMN can enter cells directly without conversion to NR
- Faster Uptake: NMN absorbs more quickly than other NAD+ precursors
- Evolutionary Advantage: The body evolved specific mechanisms to utilize NMN efficiently
- Superior Bioavailability: Direct transport means better utilization of supplemented NMN
This discovery explains why NMN supplements can be so effective at raising NAD+ levels and supporting cellular health.

More significant benefits like improved endurance, better sleep quality, or enhanced recovery may become noticeable after 1-3 months. The cellular and genetic benefits demonstrated in research studies often require several months of consistent supplementation. Remember that NMN works at the cellular level, so some benefits may be occurring even before you notice obvious changes.
Can NMN reverse aging or just slow it down?
Research suggests that NMN can reverse certain age-related changes at the cellular and molecular level. Studies have shown that NMN supplementation can restore the expression of hundreds of genes to more youthful patterns and improve various biomarkers of aging. In mice, NMN has reversed vascular aging, improved physical endurance to levels seen in younger animals, and repaired age-related DNA damage. While we cannot literally turn back the clock, NMN appears capable of reversing some functional declines associated with aging. The goal is to maintain cellular health and function at more youthful levels, potentially extending healthspan alongside lifespan.
Should I take NMN with food or on an empty stomach?
Current evidence suggests that NMN can be effectively absorbed whether taken with or without food. The discovery of the dedicated NMN transporter indicates that absorption doesn't depend on the same mechanisms as fat-soluble vitamins. Some people prefer taking NMN in the morning on an empty stomach to potentially maximize absorption and align with the body's natural circadian NAD+ rhythms. Others find it more comfortable to take with food to prevent any potential stomach sensitivity. The most important factor is consistency in your supplementation routine. Experiment to find what works best for your body and lifestyle while maintaining regular daily intake.
