Cata-Kor is a viral NAD brand that's gained huge popularity on TikTok.
With all the buzz, many people have asked me how it compares to OMRE's NMN + Resveratrol. Below, I'll break down the Cata-Kor NAD reviews & key differences so you can make an informed decision about which product is right for you.

Why OMRE Stands Out
NMN Dose
We include 500mg of ultra-pure NMN — the clinically supported sweet spot. Studies show 250mg raises NAD⁺ levels, and 500–600mg delivers optimal results. More isn't always better.
Supportive Ingredients
Our formula adds 500mg of micronized resveratrol, a proven sirtuin activator that:
- Boosts your body's own NAD⁺ production
- Supports DNA repair and cellular resilience
Together, NMN and resveratrol support NAD⁺ production from every angle.
Bioavailability
Enhanced with BioPerine®, increasing resveratrol absorption by up to 13x.
Value for money
Premium ingredients, smart dosing, real results — the best value in its class.
Is it Better to Take NAD or a Precursor Like NMN?
All the scientific studies so far have been done on precursors like NMN and NR — not on taking NAD itself. That's because NAD as a molecule is too large to pass through cell membranes. Scientists know this, which is why they use smaller building blocks like NMN or NR that your cells can easily absorb and convert into NAD+.
Is Liposomal Form Better?
Some brands use liposomal delivery and suggest it's superior. But here's the truth:
There are no published human studies on liposomal NAD, NMN, or NR. Liposomes are typically used to encapsulate fat-soluble molecules (like vitamins A, D, E, K).
NAD, NMN, and NR are all water-soluble, which means they already absorb well without needing liposomes.
How We've Formulated OMRE
At OMRE, we've built our NMN + Resveratrol formula based on published research studies. As a physician, it's extremely important to me that what we provide to our customers is proven to work.
Why 500mg NMN?
We use 500mg of ultra-pure NMN. Human studies show that doses from 250mg upwards can effectively boost NAD+ levels. Since NMN is water-soluble, absorption is excellent without needing liposomes.
Why 500mg Micronized Resveratrol?
Resveratrol is fat-soluble, which makes absorption more difficult. That's why we've chosen a micronized form, designed to improve uptake. We also use a dose that's been shown in studies to be beneficial: 500mg vs. 50mg in Cata-Kor — a 10x difference.
The Bottom Line
Both OMRE and Cata-Kor are made in the USA and third-party tested, which ensures quality. The main difference comes down to formulation:
Cata-Kor uses liposomal NAD, which is a newer approach but hasn't yet been studied in humans.
OMRE is built on the research available today — using NMN, a well-studied precursor, alongside a clinically relevant dose of micronized Resveratrol.
"I've personally formulated OMRE to be grounded in published human research. Liposomal NAD may turn out to be effective, but right now we simply don't have the data to support it. That's why I've chosen ingredients that are already backed by solid science."

OMRE NMN + Resveratrol
- 500mg of ultra-pure NMN, with independent batch testing showing 99.4%–99.7% purity.
- 500mg of micronized Resveratrol, a plant-based antioxidant found in grapes and the active compound in red wine. Resveratrol activates SIRT1, a longevity protein that further stimulates NAD+ production.
- Together, this combination doesn't just supply the best precursor — it also encourages your cells to make more NAD+ naturally.
What Makes OMRE Different?
At OMRE, quality is non-negotiable.
We use the highest quality ingredients available on the market.
We test the raw NMN powder and then test it again after the product is encapsulated. Every batch is tested twice.
The finished product also undergoes testing for heavy metals, fungi, and bacterial contamination.
All supplements are manufactured in the USA in a GMP-certified facility.

Ok, this was recommended to me by my doctor - yes, you heard that right! My actual doctor told me to start taking this - This EXACT brand! Because it has the Resvirotrol (spelling?) also in it which she said was important.
Normally I don’t go for these types if things but I trust my doctor implicitly so I ordered it.
I’ve been taking two pills per day for one month now… let me tell you what’s been happening to my body…
I’m a 56 year old guy - I workout a lot - I’m a retired Airline Pilot and I’ve always been I pretty good shape but this stuff has rocketed me into a new sphere of training I though I had left behind 35 years ago! Yes, it’s that good!
Since taking this stuff my workouts last 50% longer and they’re at least 50% more intense!!! I’m not exaggerating!!!!! Even my wife has noticed! I lift heavier, my hikes are way longer and I don’t experience DOMS afterwards.
Somehow I have more energy during the day and it lasts all day. Mind officially blown!!!
This stuff works! I am SO grateful that my doc recommended this to me… it’s not cheap! But I’ll be buying this forever!
BTW - I’m not paid or endorsed in any way by these guys or their company! I don’t know them in any way and I have zero connection to them other than getting my order in the mail from them. (Shipping was not extremely fast though - that sucked).
This stuff is amazing!!!!! Anyone reading this - try it! You can thank me later.

In 2019 a Harvard leading scientist named David Sinclair, PhD wrote a book called Lifespan - Why we age and why we don't have to. I saw him on have a discussion denoting he was the leading scientist researchin g aging. He indicated that he discovered how to stop aging; six month later in another presentation he indicated that he had discovered how to reverse aging. Unfortunately, the only product that the government allows to be sold is NMN + Resveratrol. David Sinclair takes four capsules each day. I've been taking it for almost three years now - like David I take four a day, even though the directions say two/day. Most people guess I'm 52 or 53; that just happened again three days ago. A dermatologist said my skin is that of someone who is 60. Drum roll... I am 70 years and 9 months old! This is a TRUE STORY!
omreusa1 year agoHi John, fantastic to hear about your incredible experience with our NMN + Resveratrol! Love that you're getting such positive feedback about your appearance - those age estimates are truly remarkable! Really appreciate you sharing your detailed journey and the specific observations you've experienced.

I was told I have autoimmune Hashimoto's in 2020 after I got COVID at 56 years old. I can't even begin to tell you how bone numbing and cell deep my fatigue was, and even worse, NOTHING helped. Not medication, doctors, handfuls of supplements, acupuncture, or Reiki. I could barely get off my couch or out of my bed just to purchase a few groceries , or take a shower. I thought that was going to be my life, forever, which dropped me into depression and a feeling of utter hopelessness. I researched and researched on my own and decided I'd give one more thing a shot, and that was OMRE's Resveritrol and NMN. Within 5 days of taking my first two pills, after being so ill for three years, I had the energy to get out of bed, take a shower, and I actually cooked myself a meal. Within two weeks, I could do that, AND mow my yard, or work a normal day without having to take a nap. Best of all, I actually WANTED to get up, where prior to taking the supplements, I didn't even want to wake up, let alone try to do anything more than just breathe. This supplement gave me a large portion of my life back. I still have a few “down days†a month because Hashimoto's doesn't just go away, but those days are days where all I do is take a nap, and resume my normal life straight away after it. Yes, they are on the expensive side (and being on a low fixed retirement income, hard to afford), but the benefits far, far outweigh the price. I couldn't recommend trying something more than I do this…

Started using this after experiencing painful Gout symptoms at 40. After about a month of using this, no trace of the Gout symptoms anymore.

I was looking for a Resveratrol and NMN supplement combo and this product has a high dose of each and both are 98% purity which is ideal. Also, it doesn’t contain magnesium stearate which is an added bonus.
