Why SLC NMN

Research has increasingly shown that NAD+ and it’s precursors are almost entirely digested in the gastrointestinal tract.  So, in 2017 we quit selling capsules to focus on powders and tablets designed for sublingual use, even though we were the biggest seller of NMN capsules on Amazon and through our website.

Then, two research studies were published in 2019 and 2020. The first showed the SLC12a8 enzyme prevalent in the small intestine can transport some NMN directly into cells as NAD+. The second shows that bacteria in the stomach actually consume nearly all NMN BEFORE it reaches the small intestine.

So we designed our SLC NMN with an Acid Resistant capsule that dissolves only when reaching the high pH (base) environment of the small intestine. The NMN can then utilize the SLC12a8 transporter in far greater quantity, along with other ingredients added to maximize uptake by the SLC12a8 enzyme.

Bioavailability Problem with Standard Capsules

The 2018 Liu/Rabinowitz study found that very little, if any, NMN or NR make it past the liver into the bloodstream.

Even more striking, this 2020 study found most NMN never makes it to the liver, but is almost completely digested by bacteria in the stomach.

The yellow and red bars show NMN and NAD+ in the gastrointestinal tract are many times higher in mice given antibiotics (ABX) or NMN + Antibiotics (NMN + ABX).

This explains why regular NMN capsules perform so poorly compared to sublingual delivery of NMN. Sublingual delivery can bypass the stomach and liver to deliver NMN directly to the bloodstream.

The NMN Transporter – SLC12a8

This 2019 study found some NMN (but not NR) can be transported directly through the cell membrane and converted to NAD+ by the newly discovered SLC12a8 enzyme inside the small intestine.

Does the SLC12a8 Transporter mean all NMN capsules are as effective as Sublingual?

No. The quantity that is absorbed utilizing the Slc12a8 enzyme is not thought to be the the majority.

According to the authors:

“It is important to note that the discovery of an NMN transporter by no means diminishes the importance of uptake via dephosphorylation.”

There is hope the Slc12a8 Transporter can be useful.

“Dr. Imai’s lab already has identified small molecules that can stimulate production of the Slc12a8 NMN transporter, applied for patents, and licensed this technology to a company in Japan.”

Doubts about SLC12a8

There are a some Nicotinamide Riboside (NR) believers such as Chromadex’s chief science advisor, Dr. Brenner, who refuse to accept the research on the Slc12a8 NMN Transporter, but most accept the science.

However, there is huge variation between individuals and testing to quantify how much NMN is actually transported by SLC12a8, which has not yet been published. Researchers generally believe it is less than 10% with standard delivery methods.

The Solution – Stop Digestion of NMN by Bacteria in Stomach and Maximize Uptake by SLC12a8 Transporter in Small Intestine

To maximize uptake by the SLC12a8 enzyme, it is necessary to protect NMN from bacteria in the stomach.

Delayed Release™ Capsules

Reaching the small intestines intact is critical to maximize uptake. Our Delayed Release™ capsules have been engineered to make it through the harsh, acidic environment of the stomach without being degraded. They release their payload only when they reach the alkaline environment of the small intestine.  This protects NMN from bacteria in the stomach, greatly increasing the quantity that is available for uptake by SLC12a8 enzymes in the small intestine.

Increasing uptake by SLC12a8 NMN transporter

Researchers like Dr. Sinclair are exploring methods to increase uptake by SLC12a8. Sodium is thought to be required, and making it more available may be key.

Sodium for increased uptake

Dr. Huzienga is a very well-known celebrity doctor who has conducted recent trials treating COVID-19 patients with an NMN cocktail—achieving a 100% success rate so far. (See here and here.) On advice from Dr. Sinclair, he uses Sodium Chloride to increase the uptake of NMN by SLC12a8. He also includes TMG to increase methylation and zinc to increase immunity.

Sodium Bicarbonate instead of Sodium Chloride

While Dr. Huzienga has been using Sodium Chloride (table salt) in his NMN cocktail for treating COVID-19, our team has found Sodium Bicarbonate to be a better alternative for long term usage, as many people are trying to limit their salt intake.

Alive By Science Testimonial

Improved Energy & Recovery

"I've been using the sublingual NMN for the past year and wouldn't do without it! From the first time I used it, to each time I use it, I can feel an uptick in energy and notice that my immune system seems to function better overall. I haven't been sick since we started using it! I originally tried NMN supplements because I had come down with a really bad flu last February (not Covid) and was having a hard time recovering. While I was sick I read Dr. David Sinclair's book, Lifespan, and decided to try using NMN. Wow, what a difference it made in my recovery! I got better so quickly after I started taking the supplements.

During my recovery, I took four of the sublingual tablets/day to boost my DNA repair mechanisms, and now for maintenance, I take the recommended 2/day. I've also tried both the LSG NMN and the SLC NMN and have found both to be equally as effective. I like switching the delivery mechanism for the NMN periodically to get the best response from my body. " - Jesse K.

Hair Darkening, Skin Improvements

"The darkening of my hair has been noticeable over the last 3 months or so. I take ABS Liposomal NMN and Fisetin amongst a range of other supplements.

The improvement to my facial skin & back of my hands is absolutely associated with the Renue applications. I had noticed it but when other people started commenting I felt that I had something more concrete to contribute. So in summary this is a remarkable result by any standards." - Lloyd D.

Alive by Science NMN Review

Improvements in Chronic Illness

"I have spent most of my life struggling with chronic pain and disease. I was pleased to not have any stimulating effects, but rather subtle yet very powerful changes after using nmn for only a couple of weeks. I notice deeper sleep, better recovery, and more strength during heavy lifts. I also noticed subtle mood changes, like not having that sort of blah feeling when it's darken Gray and raining outside.

I have since tried more products by Alive by science and have noticed benefits with each and every one. Their formulations are excellent and the quality of their products is Dependable through and through." - Rebekah F.

Energy Boost with Every Use

"I have been taking Pure NMN sublingual powder for about two years, and it feels like a boost of energy every time. I notice a difference in my yoga practice and strength training when I take it, my body recovers faster.

I also noticed that my vision exams have been the same in the last two years, which was never the case before. I don't know if it's related, but I would attribute it to the supplement. This is me at 39, and I feel like I have the energy of an 18 year old!" - Alexia B.

WHAT OUR CUSTOMERS SAY

"I take 125 mg before my workouts, 3-5 times a week. During resistance training I see an increased pump.

I finish with a rowing machine sprint, and taking NMN gives me a 5-10% increase in distance rowed. Very impressed with this stuff!" 

"I have a form of Retinitis Pigmentosa which has been sending me blind for the last 20 years at least. I have fought it with everything I had but was losing the fight in my late 30s. It wasn’t until I started the sublingual NMN that I felt definite vision improvements after only one week."

As part of J2Racing he has 3 in-class victories in the Carrera Cup Class of the VLN in recent years.

“I’m a committed bio-hacker with strong goals toward longevity. NAD maintenance is high on my list. I recommend this protocol to people every chance I get.”

"I am the Reigning 65-69 IRONMAN World Champion, a title earned in October 2017 in
Kona, Hawaii. I am able to detect a small “lift” when I take NMN.

I require less sleep and recover faster."

"I was taking the NMN tablets for two years, but find I like the NAD+ tablets and spray better, so have switched to those. At 61, I look at least 15 years younger than others my age. Results from Teloyears were even more encouraging as they showed my telomere length to be that of a 20 year old."

"It feels like I'm putting liquid gold on my arm. That's probably the best way to describe it.

This could be what prevents some of your aging. NAD+ is the fountain of youth. We all have NAD+ in our bodies but it decreases as we get older. I highly recommend this!"

"I LOVE these products! I've definitely noticed less redness and smoother skin around my eyes and forehead. They are the only ones I'd ever use going forward because I see actual results. Most creams and serums are overly expensive and truly don't do anything. I have spent so much money on luxury facial treatments in the past and now I will not be going back. I love the Renue skin care line.”

"I still have supple and youthful looking skin. Thanks, Renue! As a Triathlete who spends time outdoors a lot for training and racing, Renue products have made my skin look young again. I still have supple and youthful looking skin, and don't have much sun spots or damage from the sun. I look like I'm still in my late 20s, even though I just turned 40 this April!”

Why Us

ABOUT ALIVE BY SCIENCE

As the industry leader and largest manufacturer of NAD+ products, we consult with a wide range of research and clinical doctors to understand the latest research and combine that with feedback from tens of thousands of customers on our forum and Facebook Group. This helps us learn so we can offer the best quality, most effective NAD+ restoration products at the absolute lowest price. Our contributions and constant objectives are:

  • Moving science forward
  • Driving prices down
  • Setting quality standards for assurance
  • Customer service equal to none

MOVING THE SCIENCE FORWARD

We constantly strive to improve the effectiveness of our products.  So we experiment a lot. We have made great strides improving the bioavailability of NMN and NAD+ products, and enjoy a great reputation among our fast growing customer base as a result.

Sublingual NMN Powder – In 2016 we realized sublingual delivery of NMN is a much more efficient delivery method, so we stopped selling capsules and engineered an NMN powder specifically designed for stability and absorption when taken sublingually. It was an immediate success, as most users can feel a rush of energy, far different than taking a capsule.

Sublingual NMN and NAD+ Tablets – After the success of our NMN Powder, we partnered with the leading pharmaceutical sublingual products formulator to create the first NMN tablets that work similar to the powder in a more convenient form.

NAD+ Nasal Spray – Delivery to the mucosal membranes to rapidly cross the blood brain barrier for a much different effect than sublingual delivery.

Liposomal NMN, NAD+ and NR - A liposome is a tiny bubble made out of the same material as a cell membrane, and are used to protect a supplement through the digestive system and deliver intact to the bloodstream. Liposomal Sublingual Gel™ (LSG) is designed for sublingual (under the tongue) use for superior bioavailability. Our proprietary liposomal manufacturing process uses no heat, no pressure and only high-performance, pharmaceutical-grade ingredients.

Renue Skin Care Products with Liposomal NAD+, NMN, and NR - Renue™ delivers the transformative power of NAD+ along with apocynin and resveratrol across the layers of the skin using breakthrough nanoliposome technology. (1)

Restoring NAD+ in the skin has shown to be effective at treating a wide range of skin disorders, returning it to a more youthful state.

We pioneered ALL these advances in NAD+ products in 4 years, with many more coming in 2021, so stay tuned!

DRIVING THE PRICE DOWN

In 2015 when we began producing our own brand of NMN capsules, there were few manufacturers of raw material and the price was exorbitant.

We believed in the future of NMN, so made the leap and began selling at a break-even prices that were about 1/2 what others were charging, to help spur the markets.

Others were forced to follow our lead and lowered their price almost as low as ours.

We have continued with this model for 5 years now – constantly increasing the size of our orders, and seeing the manufacturing costs drop as more manufacturers see the growing market and learn how to produce the quality product we require.

We’re thrilled to be able to set our retail prices around 1/3 of what they were when we started, and continuously dropping. As always, other companies are forced to lower their prices to match ours, but can’t quite do so as we our the largest buyer and get the best pricing from manufacturers.

SETTING NEW STANDARDS FOR QUALITY

When we started selling NMN on Amazon in 2016, no-one was testing the purity of their product and displaying the proof.  Since it is an expensive product and there is no regulatory agency to insure quality, we decided to do so ourselves, and were the first to always post 3rd party test results. 

Not only do we test the raw material, but we post test reports for each batch of finished product, as it is simple for a company to just sent a sample off for testing, post that report, but not use any NMN in the bottle

A few have followed our lead now, but many others sell absolute garbage.  It is quite easy for a brand new company to pop up and slap a label on some worthless powder, buy some fake reviews on Amazon, and sell bottles to unwitting customers.  We had several tested and exposed some of the scammers, but with all the money they can make ripping people off, we couldn't battle all the new brands popping up every week, so left Amazon entirely in 2019.

Dr. Brad Stanfield has taken up the battle a bit and recently tested 21 different brands. Most had less than the advertised quantity of NMN per capsule, with several having NONE. You can see his review here.  Unfortunately, that too will have very little effect.

CUSTOMER SERVICE WITHOUT EQUAL

We never adopted the poor customer support standards of other online sellers and don’t outsource phone support to a 3rd party that has no idea what NMN is.

Call us and you will be surprised and the friendly, knowledgeable support.

Our Forum is a great resource for us and our customers to share information and feedback about what works and what doesn't.

We also sponsor trials where we give away free product to hundred of customers and learn more about how they like our products.

We learn from our customers.

One big difference between us and other supplement makers is, we actually talk to our customers!

That feedback has proven especially useful in the formulation of NAD+ products, and has helped us determine what works, without waiting years for the clinical research.

WHY ALIVE BY SCIENCE

Whether you want to help support the company driving down prices and moving the science forward with the most effective products, or if you just want the best prices for the best quality NAD+ products, ALIVE BY SCIENCE is the place.
