Your cells are the system.

NADiva™ supports the system.

Most NAD+ supplements stop at one ingredient. NADiva uses four— because cellular energy decline isn't one problem.

• NR— restores NAD+ at the source
• TMG— keeps the conversion balanced
• Quercefit®— clears what holds performance back
• Pterostilbene— activates cellular repair pathways

 

No stimulants. No quick fixes. Built for men who still train hard and plan to keep going.

FOUR-INGREDIENT SYSTEM

You're doing everything right.
So why is the gap growing?

Recovery isn't keeping up

You're training the same. The soreness stays longer. The bounce-back that used to take a day now takes three. It's not effort—you haven't lost that.

Energy is inconsistent

Not a crash—more like a ceiling. The output that used to be available on demand requires more to access. You can get there, but it costs more than it used to. 

Strength isn't responding

The work is going in. The adaptation is slower coming back. The volume that built you a decade ago now just maintains — if you're lucky. 

The math stopped working

Same inputs, smaller outputs. You've slept more, dialed nutrition, accepted harder. The return on effort has quietly declined — and none of the usual fixes explain it.

This isn't a training problem. It's not a sleep problem or a stress problem—though both make it worse. It's a cellular problem.

And most men in their 40s and 50s never hear that— because the supplement industry isn't built for them. It's built for younger athletes chasing muscle growth, not for high-mileage men trying to maintain what they've built.

WHAT'S ACTUALLY HAPPENING

NAD+ declines with age.
Everything downstream follows.

NAD+ is the molecule your cells use to produce energy. It's not a stimulant — it's the raw material that makes mitochondria work. By your 50s, NAD+ levels are roughly half what they were at 20. This isn't a theory. It's a documented, measurable decline.

1

NAD+ levels decline

Starts in your 30s. Accelerates through your 40s and 50s. Not slow, and not reversible on its own. 
2

Mitochondria lose efficiency

Less NAD+ means less fuel for cellular energy production. The engine is still there — it's running lean.
3

Output and recovery drop

Slower repair cycles. Less available energy. The margin for error in training and recovery quietly shrinks.
4

The gap compounds

Senescent cells accumulate. Repair pathways slow. Each training cycle extracts more and restores less than the one before.

It's Cellular

This isn't about pushing harder.
It's about supporting what's underneath.

THE FORMULA

Four ingredients. Four failure points. One system.

Most NAD+ supplements give you one ingredient and call it done. NADiva uses four — because the NAD+ system doesn't fail in one place. Each ingredient targets a specific breakdown point in the cascade your cells go through as you age. 
Ingredients on black slate_1025x576_387kb
SUPPLY

Nicotinamide Riboside (NR)

NAD+ precursor

Restores what age depletes at the source.

NAD+ doesn't just decline — it gets drained faster as you get older, while your ability to replenish it slows down. NR is the most direct route back. It's a precursor your cells can actually use to rebuild NAD+ levels — which means more fuel available for mitochondria to do their job, and more substrate for the repair enzymes that depend on it.

Mechanism: NR → converted to NAD+ → fuels mitochondrial energy production → activates sirtuin repair enzymes

PRESERVE

Quercefit®

Quercetin Phytosome — enhanced bioavailability form

Stops the drain most supplements ignore entirely.

Here's what most NAD+ products don't account for: an enzyme called CD38 ramps up with age and consumes NAD+ faster than your body can replace it. You can supplement NR all you want — if CD38 is running unchecked, you're filling a leaking tank. Quercefit® inhibits CD38, protecting the NAD+ you're producing so it can actually be used. It also targets senescent cells — the damaged, non-functioning cells that accumulate with age, drive inflammation, and slow recovery.

Mechanism: CD38 inhibition → preserves NAD+ levels + senolytic activity → clears dysfunctional cells → reduces inflammatory burden

BALANCE

TMG

Trimethylglycine

Keeps the system balanced while NR does its job.

Converting NR into NAD+ consumes methyl groups — molecules your body uses for DNA regulation, neurotransmitter balance, and detox pathways. Without enough methyl donors, pushing the NAD+ pathway long-term can quietly stress those systems. TMG donates methyl groups, replenishing what NR metabolism draws down. It's not a headline ingredient — it's what makes the rest of the formula sustainable over time.

Mechanism: NR metabolism depletes methyl groups → TMG replenishes them → maintains methylation balance → supports DNA regulation and detox pathways

ACTIVATE

Pterostilbene

Sirtuin activator—more bioavailable than resveratrol

Activates the repair pathways that need NAD+ to run.

Sirtuins are the enzymes your body uses for cellular repair, stress resistance, and metabolic regulation. They depend on NAD+ to function — which is why they slow down as NAD+ declines. Pterostilbene activates sirtuins directly, closing the loop: more NAD+ available, and the repair machinery that uses it switched on. It's structurally similar to resveratrol but significantly more bioavailable — meaning more of it actually reaches your cells.

Mechanism: Sirtuin activation → cellular stress resistance → improved repair signaling → supports mitochondrial function and metabolic health

Why these four—and not just one.

Every NAD+ supplement on the market gives you NR. Some give you NR plus a few extras. NADiva was designed from a different premise: the NAD+ system doesn't fail in one place, so one ingredient can't fix it. The formula covers the full cascade — supply, preservation, balance, and activation — because addressing any three without the fourth leaves a gap the other three can't close.

SUPPLY

NR

Rebuilds NAD+ where age has depleted it.

PRESERVE

Quercefit®

Stops CD38 from draining what NR produces 

BALANCE

TMG

Keeps methylation stable so the system holds 

ACTIVATE

Pterostilbene

Turns on the repair enzymes that NAD+ powers 

This isn’t a stack. It’s a system. And every piece of it is load-bearing.

WHO BUILT THIS, AND WHY

Longavus founder_scouting

Gerald

Founder, Longavus™  •  Sr. Engineer  •  High-mileage athlete  •   SFG certified

He didn't build this in a lab. He built it because nothing else worked.

Gerald is an engineer who has spent four decades designing complex systems — and four decades pushing his body in high-consequence environments. Denali. El Capitan. Remote backcountry. When his own recovery stopped responding the way it should, he applied the same framework he used on machines: find the actual failure points, fix the system, don't just manage the symptoms.

"My mother is from rural Austria. Her family didn't reach for a pill unless there was no other choice. I applied that same philosophy alongside the engineering mindset: don't cover the problem. Give the body what it needs and let it do its job."

NADiva™ is the result. Not a trend product. Not a marketing exercise. An engineering solution to a documented biological problem — built for men who refuse to accept decline as the answer.

Why not just take a stimulant?

Because that’s not the problem.

Stimulants borrow energy. They don’t create it.

You get a short lift—then the drop.

NADiva supports the system that produces energy—at the source.

No spikes. No crashes.

Just energy your body can sustain.

WHO THIS IS FOR

This is for the man who still trains—and refuses to accept what's happening.

Not the man looking for a shortcut. Not the man who's given up and wants something to blame. The man who's still putting in the work, still showing up, and quietly wondering why the work isn't returning what it used to.

If that's you — NADiva was built for you specifically.
You're in your 40s or 50s and still training hard.

Not coasting. Not "staying active." Actually training — weights, distance, backcountry, whatever demands real output.

The effort is there. The return on it isn't.

Recovery takes longer. Strength isn't responding the way it should. The math has quietly stopped working.

You've already tried the obvious fixes.

More sleep. Better nutrition. Dialed training. None of it fully explains the gap — because the gap isn't there.

You're skeptical of supplements—and you should be.

Most aren't built for you. NADiva was designed around documented biology, not marketing trends. If you want to understand the mechanism, it's all here.

You're not looking for a quick fix. You want a system.

Something that works with your body's existing machinery — not something that overrides it or masks what's happening.

THIS IS NOT FOR YOU IF

You're looking for a stimulant, a quick-fix energy boost, or something to compensate for poor sleep and poor nutrition. NADiva works with the body's existing systems — it doesn't override them. If the fundamentals aren't in place, no supplement fills that gap.

FREQUENTLY ASKED QUESTIONS

Why NR instead of NMN?

NR is one of the most studied NAD+ precursors available. It has a substantial body of human research behind it, is well tolerated, and has a clear conversion pathway to NAD+. NAD+ research is one of the most active areas in longevity science right now, and NR is where the evidence base is strongest.

NMN is promising but has a less established human research track record.

We chose NR because the mechanism is documented and the clinical data exists. We’re not chasing trends—we're applying what’s been demonstrated.

What’s actually in NADiva™—ingredients and doses?

  • NR (Nicotinamide Riboside) — 500mg
    Direct NAD+ precursor. Restores what age depletes at the source.

  • Quercefit® (Quercetin Phytosome) — 300mg
    Inhibits CD38 — the enzyme that drains NAD+ as you age. Clears senescent cells.
  • TMG (Trimethylglycine) — 500mg
    Replenishes methyl groups consumed by NR metabolism. Keeps the system balanced long-term.
  • Pterostilbene — 100mg
    Activates sirtuin repair enzymes. More bioavailable than resveratrol.

Two capsules per serving. 30 servings per bottle. No proprietary blends — every dose is listed.

When and how do I take NADiva™?

Two capsules daily—can be taken with or without food. Morning is recommended. NAD+ supports cellular energy production, so taking it earlier in the day aligns with your body's natural energy cycle.

Consistency matters more than timing. Take it at the same time each day and give it at least four weeks before evaluating results.

How long before I notice a difference?

Plan on 30 days of consistent use before you evaluate. NADiva isn't a stimulant — there's no first-dose lift. It supports cellular energy production over time, so changes tend to show up in the margins first: recovery between hard efforts, energy that holds through a long day or a heavy training week. Give it four weeks before drawing conclusions.

Will I feel it right away?

No — and that's by design. No caffeine, no stimulant, no artificial spike to feel. NADiva supports how your body produces energy at the cellular level, which builds with consistent use rather than hitting on day one. Judge it by how you recover and how steady your energy holds across a training week — not by an immediate sensation.

Is this a stimulant?

No. NADiva™ doesn't stimulate your nervous system. It supports how your body produces energy at the cellular level.

No spikes. No crashes. No dependence. It works with your body's existing machinery—not around it.

NO REVIEWS YET — AND WE'RE NOT GOING TO FAKE THEM

This is the first batch. The only honest testimonial right now is the one you'll write.

Founders are the first people to run NADiva™ in the real world. As field testers report back through their first 30 days, verified feedback goes here — names, ages, and what actually changed. Not stock quotes. Not paid reviews. The real thing, or nothing.

EARLY FEEDBACK

Recovery has noticeably improved after three weeks. I was skeptical at first... I've tried a lot of supplements. This one is different. The energy is steadier, not a spike.

M.T.

54 · Backcountry hunter · Idaho

I'm a structural engineer. I read the research before I buy anything. The formula logic here is sound. Each ingredient has a documented reason for being there.

R.K.

49 · Strength athlete · Colorado

Four weeks in. The difference isn't dramatic— it's subtle. But the gap I'd accepted as normal has quietly closed. That's what I was looking for.
