Stay capable.

Keep doing what you love.

 


 NADiva™ is a NAD⁺ support formula built for active adults whose training hasn't slowed down — even when recovery has. .

THE CHALLENGE

You’re not done.

But your body is arguing about it.

You haven't lost the drive. You've noticed the tax. Recovery takes an extra day. The ache from Saturday's session is still there Tuesday. The energy that used to just show up now has to be managed.

That's not a character problem. It's a systems problem — and systems problems have mechanisms behind them, not just symptoms.

 Do nothing, and the gap keeps widening: slower recovery, shorter sessions, more of what you love left on the table. 

THE LONGAVUS APPROACH

Staying capable is something you build.

You can't stop aging. But you can train for it.

Staying capable for the decades ahead means supporting the systems that keep you strong, resilient, and ready for what you want to do.

WHY LONGAVUS

I built Longavus because I am the customer.

 

You know the feeling. The recovery that used to be automatic now costs you a day you don't have. The energy that used to just show up now has to be managed.

I know it because I've lived it. Four decades climbing at altitude — El Capitan, Denali, ice in Alaska — running the same body other people warned me to slow down. I'm also an engineer. Four decades troubleshooting complex systems across oil and gas, manufacturing, and energy infrastructure. When something fails, you don't mask the symptom. You find where the system's actually breaking, and you fix that.

So when my own recovery started slipping in my late 50s, I ran the same diagnosis on myself — and found the same gap you'd expect: most of what's sold to people like us is built for younger people chasing muscle, not for someone who refuses to slow down and wants to do it intelligently.

Fix the engine. Don't mask the problem. That's NADiva™.

THE SCIENCE

This is where it happens

Every cell in your body runs on mitochondria like this one — converting fuel into the energy that keeps everything else working. NAD⁺ feeds that process, and it doesn't just get used up: CD38, an enzyme that increases with age, actively drains it. Most products only replace what's lost. NADiva does both — replaces it and protects it.

The Plan

Staying capable is something you build.

Here's how.

1

BUILD THE FOUNDATION

NR gives your cells the raw material they convert into NAD⁺ — the molecule your energy production and cellular repair both run on. 
2

PROTECT WHAT YOU BUILD

Quercefit® blocks CD38, the enzyme that consumes NAD⁺ faster as you age. TMG keeps your system balanced while you push it. Pterostilbene switches on the sirtuins that turn raised NAD⁺ into actual stress resistance. 
3

KEEP DOING WHAT YOU LOVE

Train. Recover. Show up. Measure the result by what you can still do — not a number on a lab report. 
Why NAD+

THE SCIENCE BEHIND NADIVA™

One thing that changes with age: NAD+ declines.

Here's what most products get wrong about fixing it.

Here's what most products get wrong about fixing it.

Body

NAD⁺ powers energy production and cellular repair. It drops as you age — and most supplements respond by dumping in more raw material (more NR, more NMN) and calling it done.

That's not wrong, exactly. It's incomplete. Because NAD⁺ isn't just a supply problem. CD38 — an enzyme that increases with age — consumes NAD⁺ faster than most people are replacing it. Add more fuel to a system that's leaking, and you're still leaking.

NADiva addresses both sides: NR raises supply. Quercefit® blocks the enzyme burning through it. That's the actual differentiation — not a bigger dose, a better-designed system.

NADIVA GOES BEYOND NR ALONE

NADiva combines NR with three supporting ingredients selected to complement NAD+ metabolism and cellular health.

NADiva™

Four Ingredient Formula

 NR + TMG + QUERCETIN +  PTEROSTILBENE 

Ingredients on black slate_1025x576_387kb

THE FORMULA

More than an NAD+ precursor.

NR is the foundation. Three supporting ingredients complete the formula.

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. 

Four ingredients. Each has a reason for being there.

No proprietary blend. No mystery doses.

THE EVIDENCE

We believe in evidence, not promises.

WHAT WE KNOW

NAD⁺ declines with age. CD38 is a primary driver of that decline. Both are established in the research — not in dispute. 

WHAT RESEARCH SUPPORTS

 In a human RCT, 48 non-professional triathletes using Quercefit® improved run performance by 11.3%, versus 3.9% in the control group. A separate double-blind RCT (78 subjects) showed measurable improvement in fatigue score, sleep quality, and physical performance over two months. 

 

WHAT WE DON'T CLAIM

Early research suggests quercetin may support the body's process of clearing old, underperforming cells — senolytic activity, shown in animal models with human data still in progress. We're watching it.

You don't have to ski off cliffs anymore.

You just want to keep getting out there.

I grew up chasing the wilderness. That turned into rock climbing, mountaineering, ice climbing, kayaking — from the Arizona desert to the Alaska Range. I climbed El Capitan, Denali among others. I spent decades in high-consequence environments where strength, endurance, and recovery weren't optional.

I'm also an engineer. Four decades troubleshooting complex systems across oil and gas, manufacturing, and energy infrastructure. My approach to every problem is the same: understand the system, find where it's failing, fix the actual failure. Don't mask the symptoms.

When recovery started getting harder in my late 50s, I applied that same lens to my own biology. I read the research. I experimented. I found NAD⁺ science and saw a real mechanism — and a real gap. Most supplements are built for younger people chasing muscle. Nothing was built for older athletes who refuse to slow down but want to do it intelligently.

My mother is from rural Austria. Her family didn't reach for a pill unless there was no other option. I didn't either. I looked for ways to support the system, not cover it up.

NADiva is the result.

Fix the engine. Don't mask the problem. 

Stay Strong — Gerald

FREQUENTLY ASKED QUESTIONS

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 at least 30 days of consistent use before you evaluate.  Six weeks is more realistic to see real changes. 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 to six weeks before drawing conclusions.


This is a long game

The version of you at 80 is being built right now.

Not by one bottle. By what you do consistently, starting today. NAD⁺ support for people who aren't done yet. 

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

NADiva™ is built with proven ingredients.

It is formulated to support you in your journey to stay capable.

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.

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.

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.
