Agemate vs Tru Niagen vs ProHealth NMN

The Supplement Everyone Is Talking About

If you have spent any time in the longevity and wellness space recently, you have almost certainly come across NAD+ supplements. They are everywhere — in longevity clinics, biohacking podcasts, and increasingly on the shelves of women over 40 who are looking for something that actually supports their health at a cellular level.

Three brands come up again and again: Agemate, Tru Niagen, and ProHealth NMN.

All three claim to raise NAD+ levels in the body. All three have real science behind them. And all three have very different price points, formulations, and approaches.

I spent a significant amount of time researching all three — reading the studies, comparing the ingredients, looking at the third-party testing, and digging into the 2026 head-to-head clinical trial that finally compared the two main ingredients directly in the same human participants.

Here is everything I found. No paid promotion. No brand relationships. Just the research.

First — What Is NAD+ and Why Does It Matter?

NAD+ stands for nicotinamide adenine dinucleotide. That is a mouthful, so let us just call it what it is: one of the most important molecules in your body.

NAD+ is involved in hundreds of biological processes — energy production in your cells, DNA repair, regulating inflammation, and supporting the proteins that help control how you age at a cellular level. Think of it as the fuel that keeps your cells running efficiently and repairing themselves properly.

Here is the problem. NAD+ levels decline significantly as we age. By the time you are in your 50s, you may have roughly half the NAD+ you had in your 30s. This decline is now considered one of the central hallmarks of biological aging — and it is one that researchers believe is actually addressable through supplementation.

NAD+ is not a wellness trend. It is a fundamental molecule that declines with age — and the science on supporting it is more serious than most supplement conversations tend to be.

NMN vs NR — The Key Difference

Before we compare the three brands, you need to understand the key difference between the two main ingredients — because this is what separates Agemate and ProHealth from Tru Niagen.

Both NMN and NR are what scientists call NAD+ precursors. They are molecules your body converts into NAD+. Think of them as two different roads leading to the same destination.

NMN — Nicotinamide Mononucleotide

NMN is one step away from NAD+. It is a more direct route. Agemate and ProHealth both use NMN as their primary active ingredient. David Sinclair — the Harvard longevity researcher whose work has done more than almost anyone to bring NAD+ into the mainstream conversation — takes NMN personally and has spoken about it extensively.

The argument for NMN: it is the more direct precursor, theoretically requiring less conversion work from the body. The question that researchers have been debating is whether NMN's larger molecular size affects how well it is absorbed.

NR — Nicotinamide Riboside

NR is what Tru Niagen uses. It is a smaller molecule than NMN, which means it can enter cells more directly. It then converts to NMN first, and then to NAD+. So it takes an extra step compared to NMN — but that smaller molecular size may make absorption more efficient.

The argument for NR: it has a significantly larger body of published human clinical research behind it than NMN does, and the smaller molecule appears to enter cells efficiently.

Think of NMN as the highway and NR as the scenic route. Both get to the same destination. The 2026 research finally gave us the most direct comparison we have ever had between the two.

The 2026 Head-to-Head Study

For years, the NMN vs NR debate was largely theoretical — there was no direct comparison in the same human participants under the same conditions.

That changed in 2026 when an independent study published in iScience — a journal from Cell Press, one of the most respected publishers in science — gave the same participants both NR and NMN at 1,200mg under identical conditions.

The finding: NR raised NAD+ more efficiently than NMN at that dose in that study.

Before you take that as a definitive verdict though, it is worth noting that a separate study found no significant difference between the two at 1,000mg. Study design matters enormously in this field — the dose, the timing, the participants, and the measurement methods all affect the outcome.

What this tells us: NR has strong evidence. NMN has strong theoretical rationale and growing evidence. And neither has been studied in the long-term human trials that would give us the definitive answer most of us are looking for.

The science is genuinely still developing. Anyone who tells you otherwise with complete confidence is overstating what we currently know.

Agemate — The All-in-One Longevity Stack

Agemate is an Australian brand that has built a significant following in the longevity community. Their flagship product is not just an NMN supplement — it is a comprehensive longevity blend.

What is in it

500mg of NMN per serving, combined with 17 additional longevity-supporting ingredients including resveratrol, spermidine, vitamin D3, K2, and magnesium. The idea is to address multiple aging pathways simultaneously rather than just raising NAD+ in isolation.

The case for Agemate

If you want an all-in-one approach — NMN plus the supporting compounds that research suggests work alongside NAD+ support — Agemate is one of the most comprehensive options available. Resveratrol in particular is often paired with NMN in longevity protocols because it activates sirtuins, the proteins that NAD+ helps power. Buying each ingredient separately would cost significantly more than the Agemate subscription price.

The considerations

At around $69 per month on subscription, it is the most expensive of the three. The third-party testing transparency is less publicly documented than the other two options — which matters in a supplement category where counterfeiting is a known problem. And because it contains so many ingredients, it is harder to isolate what is actually working if you notice changes.

Tru Niagen — The Clinical Evidence Leader

Tru Niagen is the most extensively researched NAD+ supplement in the world. That is not marketing language — it is a reflection of the investment ChromaDex, the company behind Tru Niagen, has made in human clinical research over more than a decade.

What is in it

Tru Niagen uses patented NR — nicotinamide riboside — as its sole active ingredient. 300mg per serving at the standard dose. It is available in higher doses for those who want them.

The case for Tru Niagen

More than 40 published human clinical studies. FDA GRAS certification — which means the FDA has reviewed the ingredient and determined it is generally recognized as safe. 22 separate quality tests per batch. Two Nobel Prize winners involved in the research behind it. If clinical evidence and safety data are your top priority above everything else, Tru Niagen is the clear leader.

It is also the only NAD+ supplement with the level of long-term human safety data that would make most physicians comfortable recommending it without hesitation.

The considerations

At around $40 to $55 per month, it is more affordable than Agemate but more expensive than ProHealth. It uses NR rather than NMN, which some people prefer to avoid given their preference for the more direct NAD+ precursor. And it is a single-ingredient product — which is either a feature or a limitation depending on what you are looking for.

ProHealth Longevity NMN — The Best Value Pure NMN

ProHealth Longevity is a well-established supplement company that has built a strong reputation in the longevity community for quality and transparency. Their NMN Pro product uses Uthever NMN — a branded, clinically researched form of NMN that is widely considered the gold standard in the NMN ingredient category.

What is in it

500mg of Uthever NMN per capsule. Nothing else. Pure, single-ingredient NMN supplementation.

The case for ProHealth

Uthever is the most clinically researched NMN ingredient available — independently studied and published in peer-reviewed journals. ProHealth tests their products three times through third-party labs and publishes certificates of analysis so you can verify what you are getting. The manufacturing is solvent-free, the facility is GMP certified, and the price — from around $24.95 per month — makes it the most accessible of the three by a significant margin.

If you want pure NMN, well-tested, from a transparent company, at a price that makes consistent long-term use realistic — ProHealth is the strongest choice.

The considerations

It is a single ingredient product. If you want the additional compounds that Agemate includes, you would need to source those separately. And as with all NMN products, the evidence base is still growing compared to NR.

The Third-Party Testing Problem Nobody Talks About

Before you choose any of these products, there is something you need to know about this supplement category specifically.

NMN is one of the most frequently counterfeited supplements on the market. Independent testing has found that many products claiming to contain NMN do not contain what the label says — either the dose is significantly lower than stated, or the ingredient is not NMN at all.

This makes third-party testing not a nice-to-have but an absolute requirement when evaluating any NMN product. Here is how the three compare:

• Tru Niagen: 22 separate quality tests per batch, FDA GRAS certification, the most rigorous testing of the three.
• ProHealth: Triple third-party tested, certificates of analysis publicly available, strong transparency.
• Agemate: Lab tested, but less publicly transparent about specific testing protocols and certifications.

This does not mean Agemate is not a quality product. It means that if testing transparency is important to you — and it should be in this category — Tru Niagen and ProHealth are both more verifiable.

Price Comparison — What You Actually Pay

Let us be direct about the cost, because at these price points it matters for long-term consistency — and consistency is what makes any supplement meaningful.

• Agemate Daily Longevity Blend: approximately $69 per month on subscription. Covers 18 ingredients including NMN.
• Tru Niagen 300mg: approximately $40 to $55 per month. NR only, most clinical data globally.
• ProHealth NMN Pro 500mg: from approximately $24.95 per month. Pure NMN, best value per dose.

Per dollar of active ingredient — ProHealth wins. Per overall longevity formula — Agemate wins. Per clinical evidence and safety data — Tru Niagen wins.

Which One Is Right for You?

The honest answer is that it depends on what matters most to you. Here is how I think about the decision:

Choose Agemate if

You want a comprehensive longevity stack and prefer not to source multiple supplements separately. You are comfortable paying a premium for an all-in-one formula. And you prioritize convenience and breadth of ingredients over the deepest possible evidence base on any single component.

Choose Tru Niagen if

Clinical evidence is your non-negotiable. You want the supplement with the most published human research, the most rigorous testing, and the clearest safety profile. You are comfortable with NR rather than NMN as your NAD+ precursor. And you want a product that most physicians would recognize and be comfortable with you taking.

Choose ProHealth NMN if

You specifically want NMN rather than NR. You want pure, rigorously tested supplementation without additional ingredients. You want the best value per dose. And you are comfortable with a growing but still-developing evidence base, using a well-researched branded ingredient.

What I Want You to Take Away

The NAD+ conversation is one of the most exciting and genuinely science-backed areas of longevity research right now. Unlike a lot of wellness trends, the biology here is real and the research is serious.

But it is also still developing. Long-term human data is limited for all three products. Individual responses vary significantly — some women notice dramatic improvements in energy and clarity, others notice very little. Managing your expectations while staying genuinely curious is the right posture.

All three of these brands are legitimate options from companies that have invested in quality. None of them are magic pills. And as always — if you take medications or have underlying health conditions, please discuss any new supplement with your doctor before starting.

The best NAD+ supplement is the one you will actually take consistently. Choose based on your priorities — evidence, value, or an all-in-one formula. There is no wrong answer here.

All three are available in my shop under Supplements. I have included notes on each one to help you decide which fits your goals best. 💛
