Could NAD IVs Be Bad For You (& How To Boost NAD Naturally), With Dr. Nichola Conlon

Ben Greenfield 0:00

My name is Ben Greenfield, and on this episode of The Boundless life podcast, I think a lot of people don't really realize, like, what an NAD supplement actually is.

Dr. Nichola Conlon 0:11

An important point to make is that NAD is naturally found in every single cell in our body. Anyway, there's two main things to remember when it comes to NAD that it's important for. The first thing is energy production in our mitochondria, and the second thing is for cellular maintenance and repair. That's general rule of thumb. High NAD lots of energy, lots of repair. Low NAD less energy, less repair. That's like how you can remember it in the most simplest terms.

Ben Greenfield 0:37

Welcome to the boundless life with me. Your host, Ben Greenfield, I'm a personal trainer, exercise physiologist and nutritionist, and I'm passionate about helping you discover unparalleled levels of health, fitness, longevity and beyond.

Ben Greenfield 0:59

My guest on today's podcast is Dr Nichola Conlon. She's a molecular biologist who specializes in the study of cellular aging. She had a career in drug development, and then she founded a company called nichito, which specializes in anti aging, rejuvenation and health span by boosting NAD levels. So all the show notes are going to be at Ben Greenfield life, Comm, forward slash NAD plus, like, P, L, U, S, https://bengreenfieldlife.com/nadplus here, we go. All right. Nichola, so I took NAD today, and like a lot of people, I thought I was taking NAD, but if you look at the label, it doesn't actually say NAD. It's got, like, a lot of these products will say, like, Nichola, I think nicotinamide, or is it niacinamide?

Dr. Nichola Conlon 1:50

The niacinamide and nicotinamide are actually structurally the same thing,

Ben Greenfield 1:55

all right, good. So I'm not confused that some labels say one thing and some say another. I think a lot of people don't really realize, like, what an NAD supplement actually is, or how they're designed, and you're kind of the goat with this stuff. You're a molecular biologist who studies aging and knows a lot about NAD so I eventually want to get into this idea of why a supplement says like NAD a lot of times on the front of it, but then if you look at the label, that's actually not listed as an ingredient. But before we even get into that, I would love for you to describe why people might want to think about NAD in the first place, in terms of what it does in the body, like, how the body produces it and recycles it, because I know there's some pretty complex pathways, but of anybody, you could

Dr. Nichola Conlon 2:50

probably explain them. Yeah. I mean, that's a great question. First of all, what you said about people having their NAD and then looking and going, but this has got no NAD in it, like, where's my NAD? And getting really confused, that's probably one of the most common questions that I get. But the other thing is, you know about what NAD actually is? So an important point to make is that NAD is naturally found in every single cell in our body anyway, so this is not something that we're trying to artificially add or boost or anything like that. It's something that's naturally in our cells, and it's involved in many different reactions in our body, over around 300 different reactions. But what I always say to people is there's two main things to remember when it comes to NAD that it's important for. The first thing is energy production in our mitochondria. So NAD is part of the Kreb cycle that literally helps to take the energy out of our food and turn it into ATP, which is the energy currency of our cell. So without NAD, we wouldn't be able to perform that critical act of respiration in our bodies. And the second thing that it's really important for is for cellular maintenance and repair. So aside from its role in energy production, NAD also acts as a fuel for a lot of the repair enzymes and pathways in our cells. So you know, constantly our cells are getting damaged, they're having to make sure that this damage is repaired. And a lot of the different processes that repair this damage actually rely on NAD as a fuel to power this repair. So that's general rule of thumb. High NAD, lots of energy, lots of repair. Low NAD, less energy, less repair. That's like how you can remember it in the most simplest terms.

Ben Greenfield 4:37

Okay, so if NAD is part of the Krebs cycle, and by the way, as a part of the Krebs cycle, would you call it an enzyme, a cofactor or protein? What's the proper terminology?

Dr. Nichola Conlon 4:49

I guess for NAD, it's a redox molecule. So NAD is specifically designed in its structure to flip between different states. So what it does is it flips between its oxidized. Form and its reduced form. And essentially the change between these two states is whether NAD is holding on to or donating electrons. And it's these electrons that are important for something called the electron transport chain, and that is the system in our mitochondria that creates ATP. So that's what NAD is important for there, right?

Ben Greenfield 5:21

So acceptance and donation of electrons would be its role as a redox agent in the Krebs cycle. And so that would make sense in terms of its contribution to energy production after you consume food. But for the DNA repair piece, is it simply that it plays a role in cellular repair because the body is using the ATP from the Krebs cycle to allow for the energy necessary for repair. Or does NAD play a different role than a redox agent when it comes to the DNA repair piece? Yeah, it plays

Dr. Nichola Conlon 5:59

a completely different role. So in terms of the repair and, you know, things like the DNA repair enzymes and things like that, it actually acts as a, what we call a cofactor substrate. So again, I sort of get people to visualize this as a fuel. It's like the fuel for these enzymes so that they can work. And the interesting difference is that when NAD is used for this fuel purpose, to activate repair, it's actually used up. So it's broken down into its precursors, whereas when it's used for energy production, it's not broken down. It just flips between these states of losing and gaining electrons. So it's not actually used up in that state, it stays the same amount of total NAD. It's just in a slightly different form. But when it's used for repair, it's actually completely degraded back into its precursors, or its building

Ben Greenfield 6:50

blocks, okay? And I would imagine that's where recycling comes in, because the body has to somehow get NAD back into action for the DNA repair piece,

Dr. Nichola Conlon 7:01

exactly that. And I guess this is one of the the biggest myths about NAD is that, you know, people think we get it from the outside. We get it from our diet, like somehow we're obtaining it from an external source, but actually, our body makes all the NAD it needs. Well, technically, not quite true. There's a little bit that does come from the diet, but the majority of our NAD is actually made within our cells. And our body has quite a cool little process for doing this. It's something called the NAD salvage pathway. And what happens is when NAD is used up, so when it's used for repair or it's activating things like the sirtuins, which, again, are something that kind of goes hand in hand with NAD. It's actually consumed. It's broken down into one of its precursors. And that precursor is something called nicotinamide, which we mentioned before. And then what happens is this nicotinamide is then literally picked back up by the cell, and it's converted back into NAD again through this salvage pathway. And there's an enzyme in this pathway called na MPT, and that's the main critical enzyme in this pathway. And it's quite a cool little way for the cell to manage its NAD levels effectively, because if you think about it, if NAD demand goes up, more of that NAD is going to be used. It's going to be broken down, it's going to form more precursors that then are essentially the raw material that the body then needs to then produce more NAD. So it means that as NAD demand goes up, the activity of the salvage pathway also goes up, which then meets the demand for the NAD supply. Okay, so

Ben Greenfield 8:43

NAD which it's a it's nicotinamide adenine dinucleotide, right? That's what the NAD stands for. So if the body is going to produce it in the first place, are all three of those components coming from food, like the nicotinamide adenine dinucleotide, or is it specific precursors in foods that are used to then make those because, like you mentioned, I don't think you find much like intact NAD in food versus the precursors.

Dr. Nichola Conlon 9:13

Yeah, so NAD itself is, it's very unstable. So, like, it's not something that survives well outside of the body. The precursors, on the other hand, are so precursors are like the building blocks for NAD, they're much more stable. And the building blocks for NAD are vitamin b3 which is nicotinamide, or it's derivatives. So you'll hear of things like nicotinic acid, niacinamide, nicotinamide, riboside, nicotinamide mononucleotide, nr and NMN. So these are all just slightly structurally different versions of this vitamin b3 precursor, and it's those different precursors that the body actually uses to make NAD so yes, what you were saying about. We do get those things from our diet, but ultimately, that pool of NAD that we have in our bodies is just constantly turned over. It's constantly made and recycled and made and used up and recycled again. It's not like once it's used and it's gone, we then have to get more precursor and then ensure that's turned into NAD it's actually that pathway which is self sustaining, at least it is when we're young.

Ben Greenfield 10:26

Okay, God, yeah. And I do want to talk about that. You were talking about the precursors for Nichola. Is it pure happenstance that the word nicotine sounds like nicotinamide? Or can people take solace in the fact that their zin pouches are restoring their NAD levels.

Dr. Nichola Conlon 10:42

No, definitely not that it's it's just a complete coincidence. Yeah.

Ben Greenfield 10:46

So the trope that you hear online is, well, your NAD levels decline with age, and so as you age, it becomes more important to take some kind of supplement that will restore NAD levels. It sounds to me like, from what you were just hinting at, that's true, but I would love for you to get into that, like, what actually happens when we age, and if there's something to this idea of supplementing to restore what we lost so we can continue to make energy and repair DNA?

Dr. Nichola Conlon 11:15

Yeah, absolutely. So, you know, obviously we've known about NAD for a long time for energy production, but its role in terms of repair and regeneration, that's a more, a much more newer area of science. And when scientists realize that NAD actually declines with age quite substantially. So it's estimated a half every 20 years. And this is, this is from birth. So even by the time you're 20, it's half then by the time you're 40, it's half again. What they realized was that, okay, this molecule that's actually very important for keeping our repair switched on, declines us significantly with age. So why don't we prevent this decline? So at this point, we didn't really understand why it was declining. We knew it was declining, but didn't really know the mechanism behind it. So people started to look at all different ways to boost NAD, and one of the most obvious ways was to try with pure NAD orally. Very quickly we realized that's not a possible way, because it's very unstable.

Ben Greenfield 12:15

I'm assuming that's like, synthesized in a lab. The pure

Dr. Nichola Conlon 12:18

Yeah, synthesized Yeah, like chemically synthesized NAD. I mean, by the time you even put it in your mouth, there's probably no NAD left, because it degrades just in a bottle. So yeah, in what's crazy is the amount of companies on Amazon still selling, and you know, they're highly pure, purely certified NAD, which will just not have any NAD in it by the time it gets to your house.

Ben Greenfield 12:39

Not to rabbit hole too much, because we might get to this. But could you theoretically, like reconstitute it and figure out a way to inject it in the bloodstream or intramuscularly to skirt

Dr. Nichola Conlon 12:49

those issues in the lab, if we do any experiments with NAD, the NAD is frozen and it's stored in very particular conditions, and if you're going to use it, you have to get it out and reconstitute it and use it within a very specific timeframe. So it's a tricky thing to work with, but this is why precursors became exciting, because everyone was like, okay, these precursors are the building blocks. They are not as unstable. You can take them orally. They go into the body, and if you give the body more of the raw material, hopefully it will produce more. NAD again, and we know to a certain point they do. But then we started to see all of the research coming out, which shows us why NAD declines, and the big, sort of gaping hole in this precursor theory was the main reason why NAD declines is because that main enzyme, that nampt enzyme in the salvage pathway that makes and recycles NAD from these precursors declines with age. So it's kind of like, if you go in a factory, you saw productions gone down, you realize that the machines weren't working. Like there's no way that you would think it would just be a good idea to just keep on loading the factory with raw material and hope you're going to get more NAD out at the end, right? And that's effectively what we now realize with just supplement and with simple precursors like nr or NMN, you can give the body as much as they want, but if you don't have this salvage pathway to actually turn them into anything, then you are not going to effectively boost, or sustainably boost your NAD levels.

Ben Greenfield 14:21

Okay, so it's a reduction in nampt, and would there be factors besides just age alone that might aggravate or contribute to that reduction? The reason I ask, by the way, is because I, I've personally found, and this, this is anecdote. I don't know of any actual controlled studies on this that supplementing with some form of NAD seems to help me quite a bit with sleep deprivation. So I'm wondering, you know, loss of sleep chronic inflammation like are there other lifestyle factors beyond age that would contribute to that reduction of namt, Nam?

Dr. Nichola Conlon 15:00

PT, nap, T Yeah, we'll call it that. Yeah, no, absolutely. So we know that the natural ways to activate nampt, which, by the way, is an enzyme that does naturally fluctuate. It goes up and down because it almost acts like a bit of an energy sensor in the cell. So the things that make nampt become switched on and produce NAD is when the body senses in energy stress. So this sort of idea of homeysis, where a little bit of stress kind of pushes us in the right idea, the right direction to have repair and things like that. So if you look at anything that causes an energy stress, or exercise, fasting, both of those things naturally switch on nampt, because what does that do? That increases NAD production, and what does NAD do? It gives us more energy and it gives us more repair to help the cells survive that period of stress. So on the flip side, if you look at a lot of people's lifestyles, we are sedentary, way more than we ever should be, way more than evolution designed our bodies to be, and we're also eating a lot more often and a lot more calorific foods than again, our bodies were ever designed for. So you know, one of the theories is that the reason that people are becoming much more chronically depleted in NAD is simply our lifestyles. We're not giving our bodies that little bit of homedic stress to actually switch on na and PT and, you know, increase NAD production and sleep. Sleep, sorry, I missed your other question. Sleep, really, yeah, really interesting one. So this, I think, is an area that's not spoken about enough when it comes to NAD. So sleep and our levels of NAD are actually critically important for regulating our circadian rhythm. So our whole circadian rhythm, our 24 hour sleep, wake cycle, and not just sleep, but our hormones, our metabolism, everything is controlled by two transcription factors in our cell called clock and B Mal. And these transcription factors basically switch on about 20,000 different genes on and off on his 24 hour cycle, and NAD is one of the biggest factors, or the level of NAD is one of the biggest factors that actually influences these transcription factors. So as your NAD levels fluctuate throughout the day, these influence your circadian rhythm, which is why NAD levels have such a big impact on quality of sleep. So that's probably why you've noticed that.

Ben Greenfield 17:24

Okay, I have another question related to the drop in NAD but I might need another clarification before asking it, and that's with this enzyme, the nampt, is the reduction in it only going to influence the NAD activity that's involved with DNA repair, or would the reduction of it also influence the NAD used for energy? Because it sounds to me like with energy, NAD isn't getting used up, it's just getting oxidized and reduced. But with DNA repair, it's actually getting used up, so it

Dr. Nichola Conlon 17:58

will overall lower the levels of NAD that are available. And if you think about NAD, it almost has to be prioritized in the cell. There's certain things that are going to grab it and use it. So energy production is one you know, NAD in the mitochondria is slightly different because it's it's a different pool. If you think of the mitochondria and the NAD inside the mitochondria. It's kind of enclosed in its own little membrane. So that pool kind of sits separately to the NAD pool that's in the rest of the cell that is getting involved in DNA repair and other other factors like that, the sirtuins, then, I mean, they are, you do have DNA in the mitochondria, and you do have sirtuins and things like that in the mitochondria. But genuinely, we think of them as sort of separate pools. But overall, anything that's impacting NAD production impacts everything but the ones that are impacted the most are the ones that are the consuming enzymes.

Ben Greenfield 18:52

That leads to my question, which is, if the Kreb cycle is where NAD assists with ATP production, we know that glucose is utilized in the Krebs cycle to make ATP could shifting to just like a higher fat diet and mitigating carbohydrate consumption allow for a slowing of the reduction in NA MPT and almost the ability to be able to hold On to slightly higher

Dr. Nichola Conlon 19:20

NAD levels, kind of but again, in those different when you switch them between different metabolic respiration, you know, glycolysis or aerobic respiration, oxidizing fatty acids, oxidizing glucose, you're still using NAD in its redox form. So where it's flipping between states, it's still not getting used up. The really critical things that drain our NAD supplies are repair. So number one, repair, so DNA repair. But actually perhaps even more important than that, is inflammation. So we know that one of the most prolific NAD consuming enzymes in. Our cells is something called CD 38 and CD 38 is basically an enzyme that triggers inflammatory responses in the cells. So if you think of the sort of inflammatory cascade, it kind of sits at the top, and if there's any inflammation going on, it gets activated, and it sounds it sends a downstream message to switch on inflammation in the cell, and the way it does this is by using NAD as a fuel to drive its enzymatic activity. So what we see is in people that are either chronically inflamed or generally older people who have much higher levels of just lower grade smoldering inflammation, we see increased expression of this CD 38 enzyme in their cells. And this, again, is, is, is constantly consuming NAD. And just to put it into perspective of how much it consumes. So if you imagine, again, NAD is a fuel. So for one cycle of CD 38 enzymatic activity. It uses around 100 molecules of NAD just for one cycle, for something like the DNA repair enzymes or the sirtuins, they use about six or seven. So you can see that a very small increase in inflammation can have a huge impact on NAD levels.

Ben Greenfield 21:18

Okay, now a lot of people will have heard of NAD IVs, and I think NAD patches are also becoming pretty popular as a way to just like mainline NAD into the system.

Dr. Nichola Conlon 21:34

What do you think of this? So as a scientist who has studied NAD for the last decade, I personally would not have an NAD IV. This is something that I've always said, because from a scientific perspective, if you look at the data, it doesn't make sense. So I know that there's a lot of anecdotal evidence out there. You know, people taking them saying that makes them feel much better. It helps with addiction. It does this. It does that. But if you just go back to the fundamental biology, the molecular biology, I'm a molecular biologist, after all, and look at the evidence, it doesn't make sense for a couple of reasons that the first thing is that NAD is a very large and charged molecule, if you look at its chemistry, and NAD has to get from the blood, which is ultimately where you're infusing it, or injecting it, or putting it in via a patch, or whatever it is, you know, either in the blood or in the extracellular space. It ultimately has to get into the cells to perform its function. And cells don't let things in and out like very easily. There's very few things that can just freely diffuse across the cell membrane, but the things that cells really don't like letting in are large and charged molecules. They are literally cannot get through. So that means that our cells have to have a special door or a channel to let it in, and there's still a lot of argument over whether our cells have that door or that channel to let it in. It's thought that there are some channels called CX, 43 channels, and neurons and some of our heart cells that may let NAD in. But the rest of our body, it's very unknown. So the first issue is, does it actually get into the cells? And that's a big problem. Because the second issue is that NAD does not do anything useful at all in the blood. And this is an area where I hear a lot of people saying, Oh yeah, NAD can do things outside the cell in the blood. It does things outside, but nothing helpful. The only thing that we know that NAD does outside in the blood is actually activate CD 38 and cause inflammation, which obviously we don't want to happen. The other problem is that you're putting a huge amount of a molecule that's naturally not found outside of the cells. It's found in the cells because that's where the mitochondria are, that's where the DNA is, that's where the citrus that's where NAD should be all of a sudden, you're putting a huge concentration into the blood, which is outside the cells, and the cells see that as a threat. They're like, Oh my goodness. What has happened? So I have always had this theory that Surely this must be triggering some sort of inflammatory reaction, and that's why when people have NAD IVs, they normally don't feel the best. You know, you feel sick, heart palpitations, things like that. And I've always had this as a theory, and in the last couple of months, this theory has been proven because there's a paper that's been released. It's in a pre print at the moment, I actually saw the data presented at a conference for the first time that showed within NAD IVs in a human clinical trial that it actually causes an inflammatory reaction. So they saw an increase in white blood cells, neutrophils, cytokines. Again, it makes complete sense. You put in a huge amount of an intracellular molecule outside the cell, the body's going to think, what the heck has happened? Is there a trauma? Is there some damage? And it elicits a unspecific inflammatory reaction to deal with whatever the perceived stress is. So I think that's really going to throw a cut among the pigeons in terms of IVs, but again, scientifically, it kind of makes sense.

Ben Greenfield 25:14

Yeah, okay, so we don't know whether it's getting into the cell. It sounds like it would be difficult, but the mechanisms remain unclear, but we do know that it causes inflammation. So, like, we can't say for sure, but you'd be hard pressed to find good evidence that it would be helping. So you're simply relying on, like, anecdotes that people say they feel great afterwards. And I fit into that category, like I feel awesome after. I get an ad IV, in terms of just like energy sleep that night. But I realize that's anecdotal. A N equals one. But what about some people who are using like Nichola now, which is, I think nr, if I'm not mistaken,

Dr. Nichola Conlon 25:57

as an IV, yeah, so nr is just a precursor, so you've got the same issues where, if you take a precursor orally, or take it via an IV, it doesn't matter where how you take it, you're still just giving the body more of the raw material without fixing the salvage pathway. And actually what? Again, we're now seeing some issues with this associated with this. So, for example, we spoke before about the fact that, if you the main reason for NAD decline is, first of all, the salvage pathway that that enzyme that's not recycling the NA The NAD when it's been broken down. So what should happen is NAD should be used up. It should be broken down into its precursor, which is nicotinamide, and that nicotinamide should be recycled back into NAD if you don't have adequate levels of that salvage pathway working because of the dysfunctional enzyme, what happens is we see a buildup of the precursor. So we see a buildup of nicotinamide in the cell, and cells don't like it when things build up. So when it's not getting recycled, it's building up the cells like, oh my goodness, we need to get rid of it. So what the cell does is it then switches on a methylating enzyme. So this is an enzyme called N, N, MT, right? And this methylating enzyme specifically sticks a methyl group onto the nicotinamide, and it chucks it out of the cell as methyl nicotinamide for urinary excretion. So you can start to see how, all of a sudden, we're getting this problem where, if you are ignoring these problems, and you are plowing loads of precursors into the cell, whether that's oral nr or IV nr or it's NMN that that will be getting made into NAD it will be getting used once, it will be getting broken down in nicotinamide. And then this nicotinamide is just building up and building up because your cells can't do anything with it. And then the methylation problem starts to happen. So you'll probably be familiar with people saying, oh, you know, if you take in high dose nr or NMN, you better take some time lysine or

Ben Greenfield 28:04

Sammy or some methyl donor, such, if you're a poor methylator, and you'll feel better. And by the way, I've tried this and you do, but what you're saying is that the reason that you take it and you feel better, in your opinion, is because your cells are just like crying out for extra methyl donors, not because that's a good thing, but because they need it to produce or activate this nmnt,

Dr. Nichola Conlon 28:32

exactly and this, and this isn't an opinion, actually. So this is hard fact data, and the really interesting thing is a lot of the data comes from the clinical trials on precursors. So if you look, there's a clinical study done on nr, and what they show is that if you increase the dose of nr, and measure how much NAD that turns into and basically, as the dose goes up, it gets to a certain point where it plateaus okay, then it doesn't matter how much more nr or how much more raw material you give the cell, the level of NAD just is flatlined. But they also measured the amount of methyl nicotinamide, and that just goes up. Because what's happening is your salvage pathway has reached that capacity where it doesn't matter how much more raw material you're putting in the factory, it's got to the point where it can't deal with it anymore, and it's just actively excreting it out of the cell as methyl Nichola. So, you know, the evidence is there. There's a real reason why people say take methyl donors, because it is a real problem. But for me, it's just crazy. It's like, hang on a minute. Like this is like we're going into the drug space, where we're taking a drug to fix the side effect of another drug. We're now taking a supplement. Doctors are

Ben Greenfield 29:49

now recommending a caffeine or a cup of coffee during or before as well, because caffeine can increase the NA MPT activity. So a lot of times now. If you get an NAD IV or Nichola and you're recommended a cup of coffee and a methyl donor prior, have there been any studies that you know of that have actually looked at long term, meaningful clinical outcomes of NAD IVs?

Dr. Nichola Conlon 30:18

No. So the really crazy thing is, there's actually only two studies that have looked at IV NAD in humans to look at, does it even boost? NAD? Like, two studies

Ben Greenfield 30:30

ever, does it even boost? You mean, intracellular NAD, yeah, does it

Dr. Nichola Conlon 30:35

what is it doing? Like, is it doing anything? And, you know, first of all, the the side effects aren't great when they're looking at the safety of it, but one study showed there was a small increase in NAD, but it looked like the majority of the NAD was just getting broken down into precursors, and it was the precursors that were getting taken up into the cells, in which case you then have the same problem that if the salvage pathway isn't working, then That's, you know, a recycling issue again, but the other one basically showed it didn't increase NAD, and it's causing inflammation. So, yeah, it's a, it's a, really, you know, it's probably one of the most asked questions I get. And people always say, Oh, well, you know, you're going to be biased. You have an NAD company. But, you know, as a scientist, it's, it's like, I'm only presenting, what date is there if one day, suddenly there's a great clinical study and it shows amazing benefit. That's brilliant. You know, that would be great. NAD is a great thing to boost, but at the minute that the science is just not what it shows. So I always say, have a little bit

Ben Greenfield 31:34

of caution there. You know, between now and the health optimization summit in London this September, I'm going to plot a way to get you to do an NAD IV with me in the VIP room, because I want to see, I want to see your anecdotal response and how you feel. Yeah, but, but yeah, I would basically tell people who are listening or using sub q NAD or intramuscular NAD or IV NAD or nr, you know, it's, it's, it's your own journey. And like me, if you anecdotally recognize benefit, go for it, but the research isn't there. And as Nichola just pointed out, like there, there might be potential inflammatory or methyl burden on your body. So of course, leave your questions and your comments and your feedback at https://bengreenfieldlife.com/nadplus which, is where the show notes are, because I would love to hear other people pipe in on this and ask your own questions about this. But as you just mentioned, Nichola, you have helped out with the like, like the design of an oral way to address salvage pathways and NAD precursors. It was the one that I took this morning, and like I mentioned, it's like niacinamide, which is b3 right? Yeah, yeah, b3 and then a bunch of like herbs, so or what look like herbs on the label. Can you go into the scientific rationale behind this new do you pronounce it new Cheeto? Yeah. Cheeto sounds like a fancy Mexican chip cheese and sour cream with salsa recipe, but the name

Dr. Nichola Conlon 33:17

actually derives from Japanese, actually, so Okinawa, our okay? So, yeah. So when I started getting into the NAD space and looking at all this research and seeing that the ways people were boosting NAD just didn't really make sense, based on what the data was showing us about why NAD declines, basically, I started doing a lot of research and how we could develop a formulation that's actually fixing all of these root causes of decline, so something that is not only given the body the raw material, but it's also switching back on that salvage pathway by activating nampt, it's also inhibiting CD 38 To prevent wastage of NAD because it's those two things combined that really cause its mega depletion. You know you've got, as people are getting older, not only is their production going down, but also their usage. Usage is going up because inflammation is increasing, damage is increasing, the body is using more. So you've got these two compounding factors that are making the whole situation worse. Then, on top of that, you've also got the methylation problem. Our bodies are now our cells are now increasing expression of this methylation enzyme that is effectively removing any precursor that could become NAD so you've got all these different points in the NAD system, or this NAD factory that are going wrong. And what I wanted to do was, Look, is there a more sensible way and a more sustainable way to actually fix this issue? Because at the end of the day, if something's gone down in the body, if it's declined, and we now know the reason why, surely it's better to fix a root. Cause of the problem, rather than just kind of ignore it, and, you know, chuck all the raw material in there. So this was originally a pilot formulation that we tested, and what we found is that you actually could switch back on natural NAD production. So all of these issues that we were talking about you could actually fix. So the nicita time plus formula is effectively been developed to address all of these different issues. So yes, we've got a precursor in there. So we actually use nicotinamide. We don't use nr or NMN. Simple reason being is that despite all the fuss over nr or NMN, and which one's better, if you look at the head to head comparisons with plain old vitamin b3 nicotinamide, there actually doesn't seem to be a benefit at taking these more expensive precursors. And actually, again, looking at the salvage pathway, nicotinamide is the precursor that our body naturally makes and recycles, and it's actually the only one out of all of them that can freely diffuse across cell membranes, so you can get it into

Ben Greenfield 36:04

every cell. So, right? So, so nr, NMN, would have to get reconverted back into nicotinamide to make it into the cell.

Dr. Nichola Conlon 36:12

Some of them do, but or they can get taken directly up, but they need a special channel. So remember, earlier, we're talking about these channels. Well, and not every cell has the channel. Also, there's an argument that NMN doesn't actually get absorbed itself. It gets turned to NL, nr, and then it's the NR that gets taken up. There's a bit of a debate within the world, but I think the main the Yeah, the key thing is that Nichola might is freely bioavailable. It's very well absorbed. We know it works really well. We know it's a natural precursor, so that's why we use nicotinamide. The other ingredients in there, the herbs that you mentioned, are all very much about activating and this NAD recycling pathway and dealing with some of the issues of NAD decline. So we have a couple of ingredients in there that do that. We've got two different ingredients that activate N, A M, P t, so one of them is rootin. So rootin actually is a direct activator of N, A M P t, so it directly switches on its expression, r,

Ben Greenfield 37:14

u t, e, i n, rootin,

Dr. Nichola Conlon 37:16

R u T, I n, and then the other one that we use is alpha lipoic acid. And alpha lipoic acid is an indirect activator. So the way that this works is it actually switches on something in our cells called AMPK. And AMPK is like an energy sensor. It gets switched on during exercise and fasting, and it's this AMPK that actually tells our cells to produce more nampt. So that also works via that mechanism. So we've kind of got two different mechanisms of action that are switching back on this nampt

Ben Greenfield 37:51

enzyme, ala via the AMPK pathway, and then rootin directly is switching back on the nampt.

Dr. Nichola Conlon 37:57

Yes, exactly that the other ingredients that we've got in there. So one of them is apigenin. We use this as a parsley extract. So if you see parsley on the label and like, one, there's a parsley doing it's actually because it's got a really high concentration of apigenin. Yeah, they're really, really high concentration of apigenin. And we the reason, again, we don't use pure apigenin is that's not bioavailable. You've got to take it in its its raw form, for its absorption. And this apigenin is actually a really, really good inhibitor of CD 38 and that's important for two for two reasons. The first, we don't want to waste NAD. But perhaps the even more important reason, which I haven't mentioned, is when you are boosting NAD, everyone's boosting it because they want it to switch on repair or activate the sirtuins. But the reality is that if you have any inflammation in your body, which means CD 38 is chronically overexpressed. CD 38 has what we call a high affinity for NAD, and that means it will grab NAD, if it's available in the cell, before any of the other beneficial things will even get a look in so if you are boosting NAD and you've got inflammation, and you're not inhibiting CD 38 that NAD will be inadvertently driving inflammation rather than drive and repair, and that's really important.

Ben Greenfield 39:23

And I am assuming, if CD 38 is like cleaving NAD plus, or binding to NAD plus, that would then lead to a higher need for NA, MPT and the salvage pathway. So it's kind of creating this deleterious feedback loop Exactly.

Dr. Nichola Conlon 39:41

It doesn't matter how NAD is being used, whether it's being used for good stuff or bad stuff. It's being used, it's been broken down, it's being turned into nicotinamide that piles up. The methylation problem gets worse, and you go around in this continuous cycle. And again, what we see in a clinical trial with nr is that when level. Levels of nr increase, you actually see increased levels of something called AdPR, and that's the, basically the downstream product that CD 38 makes. So given nr without inhibiting CD 38 is actually driving inflammation, and again, this is in the clinical studies.

Ben Greenfield 40:21

Let's say I was going to formulate an nr supplement. I would want some kind of a CD 38 inhibitor in there.

Dr. Nichola Conlon 40:26

Absolutely, yeah, which is exactly why we put the CD 38 inhibitor in ours. It's like, it has to, you have to address that problem. And then finally, the other sort of element in there is looking at this methylation problem. So we have a green tea in there, specifically for the reason that it contains a high level of EGCG, and that is an inhibitor of this methylating enzyme, because, again, we want to correct the system, so we're switching back on the enzyme. So our body should be recycling NAD. We are making sure the NAD is used by the correct processes, and that the breakdown products of that NAD are then not getting methylated, but they're actually getting recycled. So by inhibiting inhibiting that methylating process, you ensure those precursors that you have in the system are actually getting recycled and not excreted and methylated.

Ben Greenfield 41:16

Yeah, I looked at a paper that you guys published that showed a pretty helpful salvage pathway that was showing that CD 38 basically is producing nicotinamide or Nam, right as it cleaves to NAD. And then, from what I could understand, the NAM is getting converted into nn, MT, and because that requires increased methylation, the EGCG is acting as a sort of exactly as a methyl donor to to allow for excretion of the N and Mt. Or is EGCG doing something else besides it, like methyl donation.

Dr. Nichola Conlon 42:02

Yeah, no, so, not quite so. So when the the Nichola is broken down, sorry, the NAD is broken down into nicotinamide that piles up in the cell and that switches on the activation of this enzyme. So nnmt is a methylating enzyme, right? So what EGCG does is it inhibits that enzyme. So it means that the raw material, the nicotinamide, is now staying in the cell. It's not getting excreted. We're not wasting methyl donors, and it's getting recycled like it should be.

Ben Greenfield 42:33

Nam would normally get converted into methyl nicotinamide. EGCG is blocking that activity. So exactly more of the NAD can can get, or the NA, yeah, the NAD can get reconvert. Or the, is it the NAM that's getting reconverted? Okay, the NAM is getting reconverted in the salvage pathway to NAD.

Dr. Nichola Conlon 42:54

That's right. It's really hard to explain these without I normally have a little diagram.

Ben Greenfield 43:00

Okay, so question is, of course, does this work? I know you guys have a paper. I'll link to it in the show notes. It came out. It was pretty recently. Wasn't like last year at some point, 24 Yeah, the use of a systems approach to increase n 80 plus in human participants. What'd you guys

Dr. Nichola Conlon 43:19

look at? So this was, I think, really important for us to do this, because as a company, we pride ourselves on being, like, very scientifically credible and, you know, bringing out products that actually have good data and science behind them. My background is actually in drug development, and when I left my very credible job in drug development to start a supplement company, everyone was like, oh, supplements don't work, you know, they've got no clinical evidence data. And that's what I really wanted to change with this company, where we're bringing out products that have really good scientific thought and also have the data to back them up. So we did a full human double blind PLACEBO control crossover study. This is, you know, a gold standard in terms of trial design. And, you know, we wanted to test it. Because the other thing was, I was kind of going directly against what the whole rest of the industry was doing. Everyone was going on about nr and NMN and whether that was the best thing. And I was saying, hang on a minute. Who cares about the precursor? We need to switch back on this enzyme. We need to start our bodies naturally producing NAD again. So we really wanted to prove it worked in humans, not cells, not rats, not whatever humans. So in this clinical study, not only did we measure NAD levels, so we show that NAD significantly increases after seven days, it continues to rise. But more importantly, we showed that you can switch back on that na MPT enzyme. So again, we showed that versus the placebo, there was a significant increase in the levels of this enzyme. So not only are you boosting NAD, but you are boosting it because you are switching back on your body's own natural reproduction cycle and recycling pathway. The other things we looked at were more of the. The downstream effect. So again, I mentioned before a big worry about boosting NAD without actually looking at DD 38 or inhibiting CD 38 is that you might be driving inflammation, which, again, is what we're seeing in some of the other studies. So one of the other important things to measure was inflammation. So we measured the levels of inflammatory cytokines in these participants, and we actually showed a reduction in inflammation. So again, we're really confident that not only are we boosting NAD, we're doing this via switching on the people's own natural NAD production pathway, and then this NAD is actually going towards useful things, rather than driving inflammation.

Ben Greenfield 45:42

Okay? And then, of course, the million dollar question is, did you measure whether that was clinically meaningful when it comes to actual biological aging patterns?

Dr. Nichola Conlon 45:54

Yeah. So Well, just before we answer that, one of the things we actually did measure was biological age and these participants, so we measured a couple of other biomarkers. So one was glycated serum protein, GSP. This is something that is where it's a common biomarker measured to look at cardiovascular function. It's where sugars become irreversibly bound to the proteins in our body and causes our arteries and veins, our arterial stiffness, things like that, skin, our collagen to stiffen. That is a clinical biomarker in terms we know that that leads to increased cardiovascular disease, etc. And again, we saw a significant reduction in levels of GSP just in the 28 days that we did this study for. The other thing was biological age. So we saw a reversal of biological age. This was measured using the glycan age test of 1.26 years in 28, days as well. So we know that this is improving all around cellular health. In this study, we didn't measure any sort of clinical outcomes in terms of, is this affecting a disease status, or is this affecting quality of life and things like that, but we have done other studies since then that aren't published, but what we did measure in those different studies were a number of things, so one of them was sleep. So we get constantly reports back about anecdotal evidence that it improves people's sleep. So we did a sleep study and showed that it increases quality of sleep significantly.

Ben Greenfield 47:23

Pulling in my phone here to look at my sleep score, because I actually took it yesterday, too.

Dr. Nichola Conlon 47:26

Brilliant. Yeah, well, people look for improvements in the quality of sleep, and also HRV is what we see in when we're talking about sleep improvement. The other things that we've measured is, if you are taking a supplement to boost cellular levels of NAD and improving cellular health on the inside. Does this actually translate to improved things on the outside? So, for example, our skin because, again, we were getting so much positive feedback about skin quality, so we did a study where we looked at it was a three month study participants had no skin care changes, of skin care treatments, anything like that. They were given just the oral supplement for three months. We then measured their blood. We showed it give a significant increase in NAD but we'd also measured their skin quality with a special camera called a vizier scanner that basically takes pictures of all the redness, inflammation, lines, wrinkles, hyper pigmentation, everything like that, and saw a significant reduction that not was not just visible with the scanner, but actually visible to the naked eye in terms of redness and rosacea. So again, we showed that on the outside you can actually see a significant change. Probably part

Ben Greenfield 48:37

of that was due to the antioxidants and polyphenols that you'd be getting from like parsley leaf and green tea leaf extract and things like that too, right?

Dr. Nichola Conlon 48:44

Obviously, they're they're gonna also have other benefits as well. The other things we've looked at are in terms of quality of life, energy levels, all again, saw a significant improvement in those factors too. There we go.

Ben Greenfield 48:58

Nine 90% sleep score last night seven hours and 48 minutes. Night before, I didn't take it the day before, that was 84% at seven hours. So, you know, I'll keep tracking, but that's the only thing I've kind of changed, is to try taking your Cheeto. Now, some people might be curious, because you of course, see the idea of hormesis being a good thing, right? Mild inflammatory bursts at certain points during the week, or mild, like sympathetic nervous system stressors such as cold bath plant anti nutrients, you know, low level radiation, etc. You know earthing, grounding, sunshine, cold, heat, plants, all these things that we do for health are mild, hormetic stressors, and therefore constantly quelling inflammation or production of inflammatory cytokines might limit something like mitochondrial proliferation and. Muscle, satellite cell growth, etc. So based on that, would, would, could you make a case for the need to, like, pulse something like nichito, like, take it a few days on, a few days off? Do you do it seven days a week? Or what's your take on that? So in terms of,

Dr. Nichola Conlon 50:17

like, the inflammatory side, so say, I guess the theory that you go in with there maybe is that if we're going to inhibit in CD 38 this inflammatory drive, that maybe you're not going to get the benefits of certain hermetic stresses. When it comes to CD 38 it's it's something where it's so chronically over expressed that any inhibition of it is going to be a benefit rather than a hindrance. So I wouldn't say that would be a problem. Also. The other thing is that you just need to inhibit it such a small amount to have such a big impact because of how much NAD it uses. On the flip side, just looking at NAD itself and boosting NAD, could, you know, could having too much NAD cause this problem. Again, if you look at all of these things that that induce homeosis in the body, the vast majority of them then have their beneficial downstream effects by actually elevating NAD. So they are actually increasing NAD,

Ben Greenfield 51:16

okay, so, so you personally would be okay with taking this seven days a week?

Dr. Nichola Conlon 51:19

Yeah? Yeah, absolutely. And I'm a big fan of all, you know, I do all the things that you've just mentioned, the sauna, the heat stress, the cold shock, you know, all of those things I think are very complementary. It's, I don't want to say it, but it's almost like, you know, in some ways, for example, the ALA and the product is mimicking the type of homeatic stress that you're getting from some of these practices, like fasting, like the energy stress by activating AMPK, that's how they are ultimately working. And NAD itself is when you look at its function, obviously it's a really interesting molecule that it has such a diverse range of beneficial effects. But the really cool thing about is that intersection of where it sits between energy production on one side and repair and maintenance and switching on a lot of pathways on the other side. So if you think about, we haven't spoke about, the interaction between NAD and the sirtuins, again, the sirtuins, when they are switched on, not just having them in the cells, they've got to be switched on. We know that they activate many beneficial downstream pathways that promote cellular health, reduce inflammation, activate autophagy. The link with NAD is that they need NAD as a fuel again, so again, if you think about it, when NAD levels go up and down because of things like energy stress that then signals to this other side of the the pathways in our cell that can massively influence how the cell behaves. So NAD sits at this really neat intersection between sensing the energy of the cell and almost sensing the environment to then deciding how the cell is going to react. Is the cell going to perceive this as stress and switch on repair, or is the cell going to be like, you know, what? Loads of energy, not much stress in the environment. We'll just keep NAD turned down. We'll keep nampt turned down, and we don't need to switch on all this beneficial repair, because it costs a lot of energy. So why would we, if the body's safe, the cell's safe. So it's really a neat kind of molecule, what it does and how it does it.

Ben Greenfield 53:28

And would you classify green tea extract, root and parsley leaf or anything else in there as being a source of sirtuins? Or would one theoretically want to still include sirtuins significantly in the diet if taking a supplement like this.

Dr. Nichola Conlon 53:44

So I mean, sirtuins, it's not something like you get from the diet again. It's an enzyme. It's a deacetylase enzyme, but you can increase expression of it. I guess the big area of conversation is, what increases expression of it? There's a lot of argument that things like resveratrol can but then there's also a lot of argument that it doesn't. Interestingly, we actually measured levels of sirtuin expression in our human clinical study, and again, showed a significant increase in the levels of sirtuin in these people. And we don't even have resveratrol in there, so we know it does increase the levels of sirtuin, and it also increases levels of NAD. And put them both together, you get the beneficial things happening. So we do know that that was increased as well.

Ben Greenfield 54:28

Yeah, interesting. Okay, well, this is pretty fascinating, and obviously there's a lot of NAD nr NMN supplements out there, but you know, I've known about you and yours since the health optimization summit, I think, and now I'm using it so you guys gave us a discount. Ben Greenfield life, comm slash NAD plus, where I would love to hear people pipe in on your own thoughts. I know the the part about NAD I've. These was probably pretty surprising to a lot of you, but I would just love to hear your follow up questions on that, because I read them, and I often pass them along to podcast guests. So Nichola might have a chance to chime in also, and then her and I are both going to also be speaking or at the Health optimization summit in London this September. I'll link to that also in the show notes.

Ben Greenfield 55:24

Nichola, thank you so much for for doing this.

Dr. Nichola Conlon 55:27

No thanks for having me. It's been great to just geek out about NAD, I guess, and

Ben Greenfield 55:33

I am going to check and see if there actually is a great Mexican culinary supplement called so not Cheeto coming soon. Source, maybe they'll be like blueberry nachos for the extras or twins. But in the meantime, get your new Cheeto at https://bengreenfieldlife.com/nadplus and have an incredible week.

Dr. Nichola Conlon 55:53

Perfect. Thank you.
