Understanding NR and NMN: Biological Roles and ...
Nicotinamide Riboside (NR) and Nicotinamide Mononucleotide (NMN) are crucial NAD+ precursors supporting cellular energy and repair. While both elevate NAD+ levels to promote longevity, their absorption and conversion pathways differ, influencing their bioavailability and effectiveness. Understanding these nuances can guide optimal supplementation choices.
Key insight: NMN requires an additional enzymatic step to convert into NAD+, whereas NR is directly converted, affecting how quickly and efficiently they act in the body.
NR and NMN serve as NAD+ boosters but differ biologically. NR is a naturally occurring form in milk and beer, with excellent oral bioavailability. NMN, on the other hand, is a larger molecule that may rely on specific transporters to enter cells. These differences impact dosage effectiveness and timing when addressing age-related NAD+ decline.
| Aspect | NR (Nicotinamide Riboside) | NMN (Nicotinamide Mononucleotide) |
|---|---|---|
| Role in NAD+ Biosynthesis | Directly converted into NAD+ via nicotinamide riboside kinases | Converted into NAD+ through an intermediate step by first becoming NR or transported as NMN |
| Bioavailability | Higher oral bioavailability; easily absorbed through gut | May require specialized transporters (Slc12a8) for efficient cellular uptake |
| Molecular Size | Smaller molecule, facilitating absorption | Larger molecule, which can impact uptake speed |
| Natural Sources | Dairy, beer, certain vegetables | Found in trace amounts in fruits and vegetables |
