NR vs NMN: what’s the real difference — and why we chose NR

If you’re familiar with the concept of NAD+ boosters, or spent any time reading about longevity, you’ll probably have seen two ingredients come up again and again: NR (nicotinamide riboside) and NMN (nicotinamide mononucleotide). Both are precursors to NAD+, and both are often described as essential for “cellular energy” or “healthy ageing.”

But the two ingredients are not equally understood, equally researched, or equally reliable.

At CAMINO, we chose NR as the NAD+ precursor in our Premium Vitality Capsules — not because NMN isn’t interesting, but because the evidence for NR is currently stronger, more consistent, and much clearer in humans. This blog explains why.

Why NAD+ matters in the first place

NAD+ is a molecule your cells use for thousands of essential processes: energy production, DNA repair, metabolic health, and the daily clean-up of cellular damage. Levels naturally decline with age, which is one reason many people notice slower recovery, lower energy, and changes in vitality.

So, what’s the most reliable way to help support NAD+ as we get older?

Let's have a look at NR vs NMN

1. NR has more human clinical research behind it

This is the simplest and strongest difference. NR has been studied in dozens of peer-reviewed human trials, including research on:

• NAD+ increases

• Mitochondrial function

• Muscle recovery and performance

• Metabolic health markers

• Cognitive and neuroprotective pathways

The results are consistent: NR reliably raises NAD+ in humans.

NMN, by comparison, has mostly animal data. Human studies exist, but they’re fewer, smaller, and not yet replicated at the same level.

If you want to support NAD+ based on the most established, human-based evidence, NR is currently the clearer choice.

2. NR uses a proven, direct cellular pathway

One of the biggest misconceptions online is that NMN “enters the cell directly.” In reality, the science isn’t completely clear.

Here’s what we do know:

NR uses a well-documented pathway (the NRK pathway) to enter cells and convert into NAD+.

NMN still appears to rely on being converted into NR before the cell can use it, due it's larger molecule size — a step that makes NMN less efficient on paper.

Some animal studies have suggested a possible transporter for NMN, but this has not been demonstrated clearly in humans.

So the practical takeaway is straightforward:

NR is the direct precursor with a known route into your cells. NMN still has unanswered questions.

3. NR has clearer bioavailability data

• Reaches the bloodstream intact

• Raises NAD+ levels within hours

• Has predictable, measurable pharmacokinetics

• Performs consistently across multiple human trials

NMN’s bioavailability data is more fragmented. Results vary depending on the form, brand, and even storage conditions.

For something as fundamental as cellular energy, consistency matters.

4. NR is more stable

From a formulation perspective, this is important. NMN is chemically delicate. It breaks down easily when exposed to heat, humidity or light which are all utilised in most manufacturing processes.

NR is more stable, which means it has a better shelf life and more reliable dosing (we're ALL about effective doses!)

5. Regulatory clarity favours NR (especially in the UK & EU)

NR is permitted, recognised, and well-regulated in the UK and EU.

NMN is a patchier story. It has faced regulatory challenges in several markets, and its status is still shifting — especially where NAD+ precursors fall under stricter “novel food” rules.

We wanted to build a product that fits within clear, stable, recognised guidelines, so NR made sense from a compliance standpoint as well as a scientific one.

So, is NR “better” than NMN?

The answer backed by current research is that NR is the better-substantiated, more reliable, more predictable option — especially for humans, not mice.

That doesn’t mean NMN isn’t promising. It simply means it’s earlier in its research journey, with more unknowns than NR.

For CAMINO, choosing NR came down to four things:

• Stronger human evidence

• A well-understood biological pathway

• Better stability and consistency

• Regulatory clarity in the UK and EU

When you’re designing a product centred around cellular health and longevity, you want the most robust foundation possible. For now, that foundation is NR.

Final thought

Longevity science is fast moving, and we keep a close eye on emerging research around NMN and other NAD+ precursors. But as it stands today, NR remains the most established and reliable ingredient to support NAD+, and it’s the reason it sits alongside Monajuventa™ and CoQ10 in our Premium Vitality Capsules.
