NMN vs. NR: Comparing NAD+ Precursors
Learn the difference between NMN and NR—two popular NAD+ precursors. Compare how each works and what to consider when supporting NAD+ levels.
- NMN and NR are both NAD+ precursors—compounds your body converts into NAD+
- They differ slightly in their absorption and metabolism.
- NR has more published studies done on humans, while NMN research is still growing.
- Both are used in NAD+ supplement routines, though results may vary from individual to individual
- Eden connects you with licensed healthcare providers if you’d like to explore NAD+ injections for more direct support. Please note that you must undergo a health assessment and eligibility is not guaranteed.

What Are NAD+ Precursors?
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme essential to cellular energy and healthy DNA maintenance. But as we age, NAD+ levels may naturally decline.
That’s where precursors come in.
Precursors are nutrients which your body can convert into NAD+. Two of the most researched are:
- NR (nicotinamide riboside)
- NMN (nicotinamide mononucleotide)
Both are available as over-the-counter supplements and are being studied for their role in supporting NAD+ levels as part of a wellness routine.
How They Work in the Body
NR (Nicotinamide Riboside)
- Found in trace amounts in milk and certain foods
- Converts to NMN, which is then converted into NAD+
- used in research on metabolic function and aging
- Available in various supplement forms
NMN (Nicotinamide Mononucleotide)
- One step closer to NAD+ than NR
- Naturally present in broccoli, edamame, and avocado
- May convert directly into NAD+ in certain tissues, although research is ongoing
- Recently allowed for over-the-counter use in the U.S.
In both cases, the body processes these precursors and uses them in the same NAD+ production pathway.
What the Research Says
So far, NR has more published human studies, particularly on:
- Energy metabolism
- Muscle performance
- Cardiovascular health markers
NMN research is newer but growing. Early studies are looking at:
- Insulin sensitivity
- Cognitive markers in aging
- Cellular repair processes
It’s too early to declare a winner—both compounds show potential for supporting NAD+, but neither has been approved to treat or prevent any condition.

How to Choose Between NMN and NR
Here are a few factors to consider when selecting a precursor:
Many users try both over time or combine one with lifestyle strategies like fasting or NAD+ injections for multi-layered support.

Where NAD+ Injections Fit In
While NR and NMN are taken orally, NAD+ injections are administered under the skin, bypassing the digestive system. They are only available by prescription and may allow for:
- Personalized dosing
- Potentially more direct delivery
- Ongoing provider monitoring
For individuals who haven’t noticed results from oral supplements—or who want more consistent support—this may be worth discussing with a licensed provider.
Final Thoughts
Both NMN and NR have value as precursors to NAD+. They are widely used by people looking to support their metabolism, energy levels, and recovery routines.
Choosing the right approach depends on your goals, preferences, and how your body responds to them. And if you’re looking for a provider-supervised option, NAD+ injections may be the next step.
