The buyer had reduced a crowded market to two letters: NMN or NR. The problem was that both were described as NAD+ precursors, both had human research, and both were surrounded by claims stronger than the evidence.
Quick Answer
NMN and NR are distinct NAD+ precursors with separate products, doses, studies, and regulatory histories. Human research shows biochemical activity for both, but broad functional benefits remain uncertain. A practical choice should compare the exact formula, human evidence, testing transparency, cost, tolerability, and routine fit rather than treating one precursor as universally superior.

The Precursor Choice Notebook
| Column | What to record |
|---|---|
| Evidence | Human population, duration, dose, and outcome |
| Product | Active ingredient, serving, and other ingredients |
| Quality | Finished-batch testing and manufacturing evidence |
| Routine | Capsule count, timing, and tolerability |
| Value | Cost per serving and policy |
| Unknowns | Evidence or documents not available |
A review of 25 human NR papers cautioned that clinically relevant effects were limited and sometimes overstated.[1] Reviews of NMN likewise find biochemical effects with inconsistent broader outcomes.[2]
Why a Winner Is Hard to Name
Different trials study different people and outcomes. A biomarker result for NR does not automatically apply to NMN, and vice versa. A high-quality NR product can be a better purchase than a poorly documented NMN product, even if a buyer prefers NMN as a molecule.
Our First-Person Choice
Cromwell & Smith chose NMN for Vitalis and currently offers 500 mg beta-NMN in one capsule. That is a product decision, not proof that NR is ineffective or that Vitalis is best for everyone.

Who Is It For?
This notebook is for buyers choosing between oral precursor supplements. It is not medical advice or a reason to combine products without guidance.
What the Evidence Says
- NMN and NR are distinct molecules.
- Both have human trials, but outcomes and study designs differ.
- Product quality can matter as much as molecule preference.
- Neither precursor has proven universal anti-aging effects.

Frequently Asked Questions
Is NMN better than NR?
Current evidence does not justify a universal winner.
Do NMN and NR both affect NAD-related measures?
Human studies report biochemical effects for both, with mixed clinical outcomes.
Can you take both?
Combining supplements increases complexity and should be discussed with an appropriate professional.
Which one does Vitalis use?
Vitalis uses beta-NMN.
