Stop Running on Empty. Start Rebuilding Your Baseline.
You're not lazy. You're not "just getting older." Your cells are running low on the fuel they need to keep you sharp, energized, and resilient.
NAD+ is your body's cellular energy currency. By your 40s, levels have dropped by nearly half. The result? That afternoon crash. The brain fog that won't lift. The recovery that takes days instead of hours.
Cata-Kor™ NMN NAD+ is a complete 4-in-1 cellular energy system designed to support your body's NAD+ pathways and help you feel like yourself again.
What's Inside (and Why It Matters):
NMN (Nicotinamide Mononucleotide) fuels your NAD+ production at the source. This is the precursor your cells convert directly into usable energy.
Trans-Resveratrol activates your body's longevity pathways, helping your cells use that energy more efficiently.
Quercetin protects your cellular balance and supports your body's natural defense systems.
TMG (Trimethylglycine) keeps your methylation cycle running smoothly. Most NMN products skip this entirely. We don't.
Built for People Who've Been Burned Before:
Every batch is third-party tested for purity and potency. Certificates of Analysis available on request. Made in the USA in a GMP-certified facility. No fillers. No proprietary blends hiding weak doses. What's on the label is what's in the capsule.
Simple to Use:
Two capsules each morning. No complicated protocols. No stimulants. No jitters. Just steady, sustained support for your energy, focus, and recovery.
Protected by Our 100-Day Guarantee:
If you don't feel a genuine difference in your daily baseline, you get your money back. No questions. Less than 1% of customers ever ask for a refund.
This isn't another energy hack. It's the foundation your cells have been missing.

I stopped needing my second coffee by week two. That alone was worth it, but the mental clarity has been the real surprise.
Was skeptical after trying other NMN brands with zero results. Three weeks in and my workout recovery is noticeably faster. Solid product.
Finally something that actually works. I'm 52 and my energy feels more consistent than it has in years.

NMN (Nicotinamide Mononucleotide) is your body's most direct pathway to NAD+ production. Unlike other precursors that require multiple conversion steps, NMN converts efficiently into the cellular fuel your mitochondria need to generate sustained energy. Our formula delivers a full clinical dose to support NAD+ levels that naturally decline with age, helping restore the baseline energy, focus, and recovery you remember.
Most NMN products ignore a critical problem. When your body produces more NAD+, it uses up methyl donors faster. Without replenishment, you can end up feeling worse, not better. Cata-Kor includes TMG (Trimethylglycine) to keep your methylation cycle balanced, ensuring your body can actually use the NAD+ boost without creating new deficiencies. This is the step most competitors skip entirely.
Trans-Resveratrol and Quercetin aren't filler ingredients. They serve a specific purpose. Resveratrol activates sirtuin pathways that help your cells use NAD+ more efficiently, while Quercetin provides potent antioxidant protection and supports healthy cellular turnover. Together, they amplify the core NMN benefits and protect your cells from oxidative stress that accelerates aging.
Every batch of Cata-Kor is third-party tested for purity, potency, and contaminants before it reaches you. Certificates of Analysis are available on request. Manufactured in a GMP-certified USA facility with no proprietary blends, no hidden doses, and no fillers. What you see on the label is exactly what you get in every capsule. This is the transparency standard the supplement industry should have.
Customer Reviews
Menopause hit me hard and my energy just disappeared. I was sleeping eight hours and waking up exhausted. Brain fog was constant. I started taking Cata-Kor about six weeks ago and the change has been gradual but real. I feel more like myself again. My head is clearer in the mornings and I actually have energy left at the end of the day to do things I enjoy instead of just collapsing on the couch. I also appreciate that this company is transparent about testing and what is actually in the product. At my age I am not interested in taking anything questionable.
I have tried at least four or five different NMN supplements over the past two years and honestly started to think the whole NAD+ thing was overblown. Most of them did absolutely nothing. Cata-Kor is the first one where I actually noticed a difference. Around week three, I realized I was not hitting that wall at 2pm anymore. My workouts have been stronger and I am not dragging myself through the afternoon like I used to. The fact that it includes TMG was a big reason I tried this one since I had read that methylation support matters. Glad I gave NMN one more shot with this formula.
I work in tech and my brain is my livelihood. The mental fatigue I was experiencing was starting to scare me. I could not focus the way I used to and I felt like I was aging faster than I should be. A friend recommended looking into NAD+ supplements and after a lot of research I chose Cata-Kor because of the complete formula. It has only been about a month but my concentration is noticeably better and I am not relying on three coffees just to function. I plan to stick with this long term and see how it continues to help.

How long until I feel results?
How long until I feel results?
Most customers begin noticing improvements in energy and mental clarity within two to three weeks of consistent daily use. Some feel it sooner, others take four to six weeks. This is not a stimulant that you feel immediately. It works by supporting your cellular energy production over time, so the benefits build gradually. For best results, commit to at least 30 days of daily use before evaluating.
Why is TMG included in the formula?
Why is TMG included in the formula?
When your body produces more NAD+, it uses up methyl donors at a faster rate. If those methyl donors are not replenished, it can create an imbalance that leaves you feeling off. TMG (Trimethylglycine) supports your methylation cycle so your body can actually use the increased NAD+ efficiently. Most NMN supplements skip this entirely, which is one reason people sometimes feel nothing or experience side effects. We included it because the science supports it.
What makes Cata-Kor different from other NMN products?
What makes Cata-Kor different from other NMN products?
Three things. First, this is a complete 4-in-1 formula with NMN, TMG, Trans-Resveratrol, and Quercetin working together instead of NMN alone. Second, every batch is third-party tested for purity and potency with Certificates of Analysis available. Third, we use fully transparent dosing with no proprietary blends hiding weak amounts. You know exactly what you are getting in every capsule.
Is NMN safe to take?
Is NMN safe to take?
NMN has been studied in human clinical trials at doses up to 1,200mg per day with no serious adverse effects reported. In 2025, the FDA confirmed that NMN is lawful as a dietary supplement. Our product is manufactured in a GMP-certified facility in the USA and third-party tested for contaminants. As with any supplement, if you have a medical condition or take prescription medications, consult your physician before starting.
How do I take Cata-Kor?
How do I take Cata-Kor?
Take two capsules each morning with or without food. We recommend morning dosing because NAD+ supports cellular energy production, and some users report feeling more alert. Taking it later in the day may affect sleep for some people. No complicated protocols required. Just two capsules and you are done.
Will this keep me awake at night?
Will this keep me awake at night?
It should not if you take it in the morning as directed. Cata-Kor contains no caffeine or stimulants. However, because it supports cellular energy production, a small number of users have reported difficulty sleeping when taking it too late in the day. Stick to morning dosing and this is typically not an issue.
I have tried NMN before and felt nothing. Why would this be different?
I have tried NMN before and felt nothing. Why would this be different?
There are a few reasons NMN products fail. Many are underdosed, use low-quality ingredients, or skip important co-factors like TMG. Without methylation support, your body may struggle to use the extra NAD+ effectively. Cata-Kor addresses all of these issues with clinical dosing, verified purity, and a complete formula designed to work together. If you have been burned before, our 100-day guarantee removes your risk entirely.
