Watch How Men and Women Over 40 Are Finally Beating the Energy Crash, Clearing the Brain Fog, and Reclaiming the Sharp, Energized Version of Themselves They Thought Was Gone

Start Noticing a Difference Within the First 2-4 Weeks, With Meaningful Results Typically in 60-90 Days

* Results may vary on a case-by-case basis

Exhaustion That Doesn't Quit, A Brain That Won't Cooperate, And The Feeling That Age Is Catching Up Is Exhausting Everyone Over 40

Why can't vitamins, sleep, and a clean diet fix the way you feel anymore?

There's a little-known reason why people over 40 struggle with low energy, brain fog, and slow recovery, no matter what they try.

 

That little-known reason is something most doctors rarely explain: NAD+ Decline.

 

Think of NAD+ as the fuel that powers every cell in your body.

 

It's a molecule your cells absolutely depend on to produce energy, repair DNA, run your metabolism, and keep your brain firing on all cylinders.

 

Under normal conditions, your body produces enough NAD+ to keep you sharp, energized, and resilient.

 

The problem is that nothing about your 40s is "normal conditions" for NAD+...

 

Because starting in your 30s, your NAD+ levels begin to fall. By the time you're 50, studies suggest you may have only half the NAD+ you had at 20. By 60, potentially less.

 

The result: a body that runs on depleted fuel.

 

That's why the 2pm energy crash hits harder. Why recovering from a bad night's sleep takes three days instead of one. Why the mental sharpness that used to come naturally now feels like it has to be fought for.

NAD+ levels in the body can fall by up to 50% between ages 40-60, with continued decline thereafter

Human clinical studies show 500mg NMN daily can raise NAD+ levels by 60-100% within 60-90 days

Most energy supplements only address surface symptoms -- they do nothing to restore NAD+ at the cellular level

Result?

This keeps millions of adults trapped in a cycle of fatigue, brain fog, and slow aging - no matter how well they eat or sleep.

That's why people are reaching for adaptogens that don't adapt, trying caffeine that just crashes harder, and spending money on supplements that never get to the root.

 

But this ends NOW!

All It Takes Is Two Capsules A Day To Give Your Cells The Fuel They Need

Cata-Kor NMN 4-in-1 contains four ingredients backed by human studies and longevity research. They have been precisely combined to restore NAD+ levels, protect your cells, and support healthy aging...

Without expensive IV drips, prescriptions, or complicated protocols.

NMN (Beta-Nicotinamide Mononucleotide) - 500mg

Your body uses NMN as the direct building block to produce NAD+. At 500mg -- the clinically studied dose -- NMN has been shown in human trials to raise whole-blood NAD+ levels by 60-100% within 60-90 days.

 

NMN enters your cells and is converted into NAD+ through a natural biosynthesis pathway. This is the most direct and efficient way to raise NAD+ levels without using an IV drip. Once inside the cell, that new NAD+ goes to work immediately: fueling mitochondrial energy production, activating DNA repair enzymes, supporting your metabolism, and giving your brain the molecular fuel it needs to stay sharp.

 

This is the engine. Everything else in the formula makes it run better.

TMG (Trimethylglycine) -
250mg

When NMN converts to NAD+, it consumes methyl groups from your body's methylation pool. If those methyl groups aren't replenished, your body starts to self-limit NAD+ production -- and the benefits you're working toward plateau or stall entirely.

 

TMG is a methyl donor. It continuously replenishes the methyl groups that NMN conversion consumes, keeping your NAD+ recycling pathway running efficiently over the long term. It also supports healthy homocysteine levels and liver function as a secondary benefit.

 

Most NMN products skip this ingredient because it adds cost. We include it because without it, you're running the engine without coolant.

Quercetin (from Sophora Japonica Bud Extract) - 150mg

As you age, your body accumulates senescent cells -- old, damaged cells that have stopped dividing but refuse to die. These cells release inflammatory signals that create a toxic environment for healthy cells around them, accelerating the aging process and undermining the cellular repair work that NAD+ supports.

 

Quercetin is one of the most studied senolytic compounds in longevity research. Clinical research shows it can help reduce the load of these aged cells, clearing the environment so that healthy cells -- now fueled by restored NAD+ -- can function without interference.

 

Think of it this way: NMN fills the fuel tank. Quercetin clears the debris off the road.

Resveratrol (from Polygonum Cuspidatum Root Extract) - 100mg

NAD+ activates your sirtuins -- a family of longevity proteins that regulate DNA repair, cellular stress response, and metabolic health. But NAD+ alone doesn't maximize sirtuin activity. Resveratrol does.

 

Resveratrol is a direct activator of SIRT1, the sirtuin most associated with DNA repair and the biological aging process. When resveratrol and NMN are taken together, resveratrol amplifies the effect of the NAD+ you've restored -- making every unit work harder and reach further into the aging pathways it's meant to address.

 

This synergy between NMN and resveratrol is the reason longevity researchers have stacked these two compounds together for years. We built that stack into every capsule.

Sandra M.

I was skeptical at first because I had tried so many supplements before. Within three weeks, I noticed I wasn't falling asleep after work anymore. By week six, the brain fog I had been chalking up to just getting older had genuinely lifted. I'm on my third jar and I have no plans to stop.

James T.

I'm 58 and I thought the low energy was just permanent. My wife noticed I seemed sharper before I even said anything. That told me something real was happening. I've been on it four months now and recovery from workouts is noticeably faster too.

Linda R. 

I've tried other NMN brands at lower doses and felt nothing. The difference with 500mg plus the full stack is real. My sleep is deeper, my focus is sharper, and the afternoon crash I used to dread every single day is just gone. I feel like I bought 10 years back.

Still Not Sure? Here Are The Top Questions We Get About Cata-Kor NMN

What is Cata-Kor NMN 4-in-1 and how does it work?

Cata-Kor NMN 4-in-1 is an advanced NAD+ support supplement designed to help restore the cellular fuel your body loses with age. The core ingredient is 500mg of pharmaceutical-grade NMN (Beta-Nicotinamide Mononucleotide) -- the clinically studied dose shown in human trials to meaningfully raise NAD+ levels in the blood.

 

Here's how it works: NMN is a direct precursor to NAD+, meaning your body converts NMN into NAD+ at the cellular level. NAD+ is the molecule your cells need to produce energy, repair DNA, run your metabolism, and keep your brain functioning at its best. After your 30s, your body produces less and less of it naturally. Cata-Kor NMN gives your body the raw material to restore what time has taken away.

 

The formula also includes three supporting actives: TMG to keep the NAD+ recycling process running efficiently, Quercetin to help clear aged and damaged cells that slow your cellular environment down, and Resveratrol to activate the longevity proteins that NAD+ powers. Together they don't just raise NAD+ -- they make sure your body uses it well.

How long will it take to see results?

Most customers notice the first shifts within 2-4 weeks -- typically a more stable energy level through the day, less of that mid-afternoon crash, and a subtle lift in mental clarity.

 

The deeper results build over time. NAD+ works at the cellular level, and cellular repair is not something you feel overnight -- it accumulates. Human clinical studies show NAD+ levels rising significantly at the 60-90 day mark with consistent use at 500mg daily.

 

A realistic timeline looks like this:

 

Weeks 2-4: Energy starts to stabilize. Afternoon crashes become less severe. Sleep may begin to feel more restorative.

 

Weeks 4-8: Mental clarity improving. Less brain fog. Faster recovery after physical exertion or poor sleep.

 

60-90 Days: NAD+ levels measurably rising based on clinical data at this dose. Most customers report this is where the full picture becomes clear.

 

90+ Days: Cellular repair processes running consistently. Benefits compound with continued use.

 

If you've tried other NMN products at lower doses and felt nothing, this is why dose matters. 250mg or less is simply not the clinically studied threshold. 500mg is.

Who should use Cata-Kor NMN?

Cata-Kor NMN is designed for adults over 35 who are experiencing the gradual symptoms of NAD+ decline -- low energy that doesn't respond to sleep, brain fog that's getting harder to ignore, slower recovery, or simply the feeling that their body isn't running the way it used to.

 

It works particularly well for:

 

Men and women in their 40s and 50s noticing energy and cognitive decline Anyone who feels like they're fighting fatigue no matter how well they sleep or eat People who want to be proactive about healthy aging rather than reactive Those who have tried basic supplements and vitamins without meaningful results Biohackers and longevity-minded adults looking for a properly dosed, full-stack formula 

 

If you are pregnant, nursing, or currently taking prescription medication, please consult your doctor before starting any new supplement.

Are there any side effects?

Cata-Kor NMN 4-in-1 is well-tolerated by the vast majority of customers. The ingredients are naturally derived and have been studied in human clinical trials without significant adverse effects at these doses.


A small number of people report mild digestive sensitivity when first starting, particularly if taken on an empty stomach. If this applies to you, take your two capsules with food.

 

A very small percentage of users report mild headaches in the first week as their body adjusts. This typically resolves within the first 7-10 days.

 

If you experience any persistent discomfort, discontinue use and consult your healthcare provider. As with all supplements, individual responses vary.

How do I take Cata-Kor NMN?

Take two capsules daily, ideally in the morning with or without food. Morning use aligns with your body's natural energy cycles and gives the formula time to work through the day.


Consistency is everything with NAD+ supplementation. The cellular repair process builds over weeks and months of daily use -- skipping days extends the timeline for results. Set a daily reminder if needed and treat it like any other non-negotiable part of your morning.


Do not exceed two capsules per day unless directed by a healthcare professional.

What if it doesn't work for me?

Then you don't pay for it. Simple as that.


Every order of Cata-Kor NMN is covered by our 90-Day Money-Back Guarantee. If after 90 days of consistent daily use you haven't noticed a meaningful difference, contact our support team and we'll refund your first jar -- no questions asked, no hoops to jump through.


We offer this guarantee because we're confident in the formula. 500mg NMN at this dose, backed by human clinical data, is not a gamble -- it's a commitment to the science. The guarantee is there so the risk is entirely ours, not yours.

What makes this different from other NMN supplements?

Most NMN products on the market cut corners in one of three ways: they underdose the NMN, they include no supporting actives, or they skip third-party testing entirely.


Cata-Kor NMN addresses all three:


Dose: 500mg NMN per serving -- the clinically studied threshold shown in human trials to produce meaningful NAD+ increases. Many competitors use 250mg or less and call it effective. It isn't at that level.


Full stack: Most NMN-only products ignore the fact that NMN conversion depletes methyl groups, which can stall NAD+ production over time. We include 250mg TMG to keep that process cycling. We add Quercetin as a senolytic support compound and Resveratrol to activate the sirtuin proteins that NAD+ powers. This isn't NMN plus filler -- every ingredient has a job.


Third-party tested: Cata-Kor NMN is tested by Alkemist Labs for purity, potency, and heavy metals. You know exactly what you're getting.


Made in the USA in a GMP-certified facility.

Is Cata-Kor NMN safe for long-term use?

Yes. NMN has been studied in human clinical trials for periods of up to 12 weeks and longer with no significant adverse effects reported. The supporting ingredients -- TMG, Quercetin, and Resveratrol -- all have well-established safety profiles in human research.


NAD+ is not a foreign compound. It is a molecule your body produces naturally and depends on for basic function. NMN supplementation is simply restoring what age depletes.


Long-term daily use is not only safe -- it's recommended. The benefits of NAD+ restoration compound over time. Customers who have used Cata-Kor NMN consistently for 6 months or more consistently report the best results.

Where is it made?

Cata-Kor NMN is manufactured in the United States in a GMP-certified facility. Every batch is produced under strict quality control protocols and third-party tested by Alkemist Labs for purity, potency, and the absence of heavy metals and contaminants.


We do not manufacture in facilities that cut corners on testing or sourcing. The pharmaceutical-grade NMN in every jar meets the same standard you'd expect from a clinical-grade product.

Does 500mg NMN actually make a difference vs lower doses?

Yes -- and this is one of the most important things to understand before buying any NMN supplement.


The human clinical studies that demonstrated meaningful NAD+ increases used 500mg per day as the effective dose. A double-blind, placebo-controlled trial published in 2023 showed that 500mg daily raised whole-blood NAD+ from 23.8 to 41.7 micromoles per liter in 60 days -- approximately a 75% increase. A meta-analysis of 107 participants across multiple trials confirmed blood NAD+ rises of 60-100% at the 250-500mg range.


Products dosed at 100mg or 150mg are not replicating these study conditions. You are paying for a supplement that has not been validated at the dose it's delivering. With NMN, dose is not a minor detail -- it is the primary variable that determines whether anything happens at the cellular level.


500mg is where the clinical evidence lives. That's what's in every jar of Cata-Kor NMN.
