The #1 Reason People Die (You'll Be Surprised!) & How To ARM Your Gut So It Doesn't Happen To YOU! Just Thrive With Tina Anderson and Kiran Krishnan

My name is Ben Greenfield, and on this episode of the Ben Greenfield Life.

Podcast, we created a whole entire new category in the probiotic space. Spores have the ability to survive the gastric system naturally. So it's not like we do any intercoding or anything like that. They have this endospore shell around themselves that allows them to withstand the body temperature and also withstand the very acidic environment of the stomach. And when they get to the intestines, that's when they take their shell off, their endospore shell off, and that's when they go into their live vegetative CE state and where they start to work throughout the digestive system. And these strains, once they get to the intestines, they stay there for about 21 to 28 days. Where most probiotics out there would just simply pass through similar to food, these strains actually stay there for about 21 to 28 days, making a true change.

In the gut flora, fitness, nutrition, biohacking, longevity, life optimization, spirituality, and a whole lot more. Welcome to the Ben Greenfield Life Show. Are you ready to hack your life? Let's do this. Well, everybody, I get to invite and interview two pretty smart cookies. On today's show, I have a research microbiologist who specializes in the human microbiome and wellness. Kiran Christian is my first guest. And Karen is joined by Tina Anderson, who actually began her career as a trial lawyer and now she is in the probiotics industry. So as you probably have already guessed, based on Tina and Koran's background, we're going to be talking all things probiotics in today's show. And I have plenty of my own stupid questions about probiotics to ask you guys. So what do you think? You ready for this?

I'm ready.

Oh yeah, let's do it.

Okay, cool. You guys are with a company called Just Thrive. I actually had some of your gummies. You have these Just Thrive gummies. I had them in my smoothie this morning. Believe it or not. Basically every morning is a competition to see how many different things I can squeeze into a smoothie. But tell me about how Just Thrive got started.

Yeah. So my husband Billy and I were in the pharmaceutical industry for several years and we thought it was great. We're thinking, oh, we're delivering life saving medications. We're making a huge change in the world helping people feel better. But after being in the pharmaceutical industry for several years, we started to see a lot of the abuses in the industry. The over prescribing of medications. We saw it with our own family members you know, we'd see one pharmaceutical, she'd be on one, and then before you know it, she'd be on a different. 12 different medications and never getting any better. And so we are really focused on mindset. We're deep thinkers, and we just felt that we weren't doing our life's work. And so we. My husband was seeing a naturopathic physician who worked with Karan. And through, I think, being at the right place at the right time and a lot of meditation, we were able to license these strains out of London University, these probiotics spores out of London University. And from there, that's where just thrive was born and spin the most amazing experience I've ever. I've ever gone through in my career.

How do you license a probiotic spore? How's that work?

Let me touch on, you know, my. My perspective on why I got into the probiotic industry and was fortunate enough to partner with Tina on it. So I started looking at the probiotic industry from microbiologist perspective, and a lot of things just didn't make any sense. And then I come along and I meet this functional medicine doctor who has like a 95% gut practice, gut focused practice. He approached almost every chronic condition by dealing with the gut, and yet he didn't use a single probiotic in his practice. And that was baffling to me. Right? So that was. It caused me to ask a lot of questions. And. And when I started asking him, why do you not use a probiotic? He was using ferments and prebiotics and lots of other things. He said, because I've tried so many of them and most of them don't really do a lot. Maybe they'll do something in the beginning, but then you'll see the effects fade and all that. And it kind of resonated with me because when I started getting into supplements and nutrition and all that for athletic purposes and for endurance and performance purposes, and I started looking at probiotics, I was like, the way they're formulating these things, packaging them, putting them in refrigerators, adding all these crazy capsules and all that, most of that doesn't make any sense. And so we wanted to rethink the idea of what a probiotic truly is and how you approach it from a formulation perspective. And so one of the ways in which you advance your project in terms of building your own proprietary probiotic is you have to find the right strains. And I'm sure we'll talk about what the right strain means and what it should be doing. But there's a lot of academic researchers that have spent a lot of time and a lot of grant money isolating strains from numerous sources. Now, for probiotics, you want to isolate strains generally from the human gut microbiome, because these are strains that then have some familiarity with functioning in the gut microbiome, which is a very complex ecosystem. They isolate the strains, they characterize it properly, they do full genomic sequencing. So we know every single protein and every single gene on those strains. And then they start to study what some of the strains functions are. If you have connections with these academics, then you can approach them and say, hey, I know in your academic pursuits you've isolated these strains to try to learn about them, but we'd like to commercialize them. And if you can work out a deal with them, you can basically license the mother culture, if you will, the original strain that they isolated, and then you get access to that and all of its genomic information to try to scale it into a commercial scale, commercial strain, so that you could produce at a commercial scale. So that's the kind of deal we would do. And we did that with London University.

So when you say isolation, please don't tell me that that's just like random healthy donors pooping in a toilet bowl and the researchers collecting it with a spoon and putting in a food dehydrator or something like that.

Unfortunately, that is. Yeah, yeah, really, it's collecting a lot of poop. Right. So if you think about a sample of poop may have upwards of 2,3000 different species in there. And the idea is to collect maybe samples from all different parts of the world, so you get an understanding of what the population distribution looks like of microbes in different people from different parts of the world. And so then you take stool and then you rehydrate it and you create a slurry and then you actually spin off using centrifuges, all the bigger, more massive things like the fibers and things that didn't get digested well or absorbed. And then you try to spin down what we call into pellets. These pellets are basically concentrated bacteria. So you're separating all of the matter and the debris from the fecal matter, if you will, and you're isolating the bacteria. Now, when you have these little bacterial pellets, then they start growing these bacterial pellets up in flasks and plates and things like that. And then you start streaking them and isolating colonies, because every bacteria will have a slightly different colony. Then you pick the colonies, you do genetic sequencing and you try to figure out what they are. So it is a lot of shit work, if you will, because these, the researchers are literally dealing with pounds and pounds of shit from all over the world.

And if I find a piece of like corn or carrot slice in my probiotic capsule, that means they didn't do a good job with the centrifugation.

Exactly. But it's probably healthy for you, so I wouldn't be too alarmed. So.

Well, it's good to know that they can isolate it and grow it and that if your guys just thrive becomes, you know, a $10 billion company, that you aren't going to run out of people pooping in order to keep up with the probiotic production.

So that's an important one. So a lot of people have a misconception that when you use a human isolate strain, that the continuous supply of the strain continues to come from people. But it's not. Once you isolate a strain and you have the original strain, the original culture, you can keep that strain indefinitely in the freezer for thousands of years. So we have the original strain that was isolated something like 15 to 20 years ago sitting in a freezer, and numerous copies of that strain sitting in little tiny, little tiny vials in a freezer in minus 80 degrees Fahrenheit. And every time we do a production, we actually pull one of those little things and we inoculate a vessel with it and allow it to grow, and then we inoculate the next vessel and so on. So it's sitting there in the freezer. We never have to go back to the human source again.

That is so cool. Tina, when you came to Quran, did you already have in mind what strain that you wanted?

No, we didn't. We were looking at gut health because we had learned about the importance of gut health. That was shortly after the Human Microbiome project was launched by the National Institutes of Health. Told us more about the gut than we ever knew before. And we just knew we wanted to get into the gut health space. But we had talked to the functional medicine practitioner that Karen had mentioned, and he's like, the probiotics out there just aren't working. They're not working. And one day he called us into his office and he said, you will not believe this, but we have the opportunity to license these strains at a London university. And he's like, this is the real deal. This works. And so that's kind of how it happened.

Okay, so tell me more about the strains.

So they're bacillus spore strains. And one of the biggest, you know, differentiators of it is it's their ability to survive the gastric system. We created a whole entire new category in the probiotic space. Spores have the ability to survive the gastric system naturally. So it's not like we do any intercoding or anything like that. They have this endospore shell around themselves that allows them to withstand the body temperature and also withstand the very acidic environment of the stomach. And when they get to the intestines, they. That's when they take their shell off, their endospore shell off, and that's when they turn into a live vegetative. They go into their live vegetative cell state and where they start to work throughout the digestive system. And these strains, once they get to the intestines, they stay there for about 21 to 28 days. Where most probiotics out there would just simply pass through similar to food, these strains actually stay there for about 21 to 28 days, making a true change in the gut flora.

So could anybody just wander in, like, could I just start whatever, greenfield probiotics.com and go wander in and get that same strain and use it? Or are you guys able to somehow protect that at thrive?

Yeah, just thrive. We're able to protect it. We have a supply agreement and exclusivity, and that's what we've been able to secure.

Have you figured out a way to combine that strain with anything else that makes it more effective?

Well, we have combined it with other bacillus spore strains. And that's a really great question, because one of the biggest problems in the industry that we're seeing is these kitchen sink formula probiotics there, where they say they have 10, 15, sometimes 20 different strains in the product and they don't know what they're doing together. That is one of the biggest things we have been trying to push in the probiotic industry is get a study on the finished formulation. Because these are live microorganisms, we don't know how they're going to play with each other. UC Davis did a study. They took 16 children's probiotics and found that only one of them met label claims. They tested them. Only one of them met label claims. So that means 15 of them either didn't have a strain that was listed on the label or they had even worse. They had a strain that wasn't listed on the label that nobody knew about, nobody had studied. They don't know anything about. So we are very Proud of the fact that we've done human clinical trials on our finished formulation.

What kind of stuff have you found out in your trials?

Well, we did a leaky gut, double blind human clinical trial in leaky gut showing that these strains are reducing the LPS from leaking into the bloodstream by 42%. That study was profound because we also found people who were in the placebo group actually saw a 32% increase of LPS after 30 days.

Yeah. And by the way, LPS explain that to people who might not know what that means.

Sure. It stands for lipopolysaccharide. It's a toxin that's found in our gut flora. It's not really problematic. It becomes really problematic when it seeps out of your intestines and goes into your circulatory system and causes this inflammatory response. And so the leaky gut study is profound. Karan was super involved in that, you know, in setting that up with University of North Texas, so he could probably speak to it even more. But it is, it's a really, it's the first study that I know of, I don't know of any other probiotic or any other pharmaceutical for that matter that has a study on leaky gut or metabolic endotoxemia.

Any other cool trials.

Yeah. So we've done a number, and I want to elaborate on the leaky gut study as well a little bit. But some of the other trials are we did a study on liver function.

Right.

So there's this endohepatic circulatory and protection axis, meaning there's a deep connection between your gut microbiome and your liver and how your liver functions as a result of your microbiome. Now, what we were able to see in this study is that the right type of microbiome and the right type of probiotic can actually protect the liver in damage. Now, this was an animal study because you can't induce damage in liver in humans on purpose, at least. What we did is we took animals and then you overdose the animals in acetaminophen. So this is a mouse study. And then in one group of animals, we used clinically graded milk thistle and actually which is a prescription drug in parts of Germany. And then we used the probiotic spores, the just thrive spores. And what we saw was that the just thrive spores were able to protect the liver of the animals from damage from the overdosing of acetaminophen as well, and in some cases better than the milk thistle did. So negating any of the damage from overdosing it. And that just goes to show the intimate connection between all these other body systems and a healthy microbiome and having a healthy probiotic that facilitates a microbiome. And the leaky gut study that Tina mentioned, the reason we became so interested in that is back in 2012, we were pondering and thinking like, okay, if we had the best probiotic there is, what would we want it to do? What is arguably the most important function of a probiotic? Because there's lots of things probiotics can do, right? They can alleviate gas and bloating and diarrhea or constipation, all the digestive issues. And those are all important. But what would we want to do to really move the needle in human health? It became clear that we wanted it to resolve intestinal permeability, because intestinal permeability comes about as a result of a change in the microbial environment in the gut. Right? Your gut is naturally designed to not be overtly permeable. It has a dynamic permeability, meaning it allows things to go through. But then there's lots of things that it shouldn't allow to go through, including this LPS endotoxin. So when you lose that dynamic permeability and your gut becomes openly permeable, you start to get a lot of chronic, low grade inflammation, and that becomes one of the biggest sources of chronic low grade inflammation. And as you know, that becomes the foundation for most chronic disease, right? So we saw a publication in 2015, which is a meta analysis of this topic, and they looked at something like 30 different published human clinical trials, and they concluded that the number one cause of mortality and morbidity worldwide in the developed world was intestinal permeability as a result of microbiome number one. Right? It's the number one killer worldwide, and it causes more mortality and morbidity than anything else worldwide because it's the foundation of so many chronic conditions like cardiovascular disease, dementia, Alzheimer's, diabetes, all of these things. And then the American Diabetic association, which is normally way behind on advances, published a number of studies from 2013 all the way to 2018 showing that metabolic endotoxemia, that's the scientific definition of leaky gut, is the initial insult that starts the process of insulin resistance in the vast majority of people. So we said, okay, if we can get a handle on this issue of leaky gut, if we can give people a tool that can stop that open permeability in the microbiome, then we're really moving the needle on foundational health. They still have to do all kinds of other things to be healthy. But this moves the needle. And so we did that study and we published it in a journal called the World Journal of Pathophysiological Gastroenteroenterology. So it doesn't roll off the tongue, but it's very good for gut nerds. And it's an open source journal, so we're able to share the study. And we for the first time showed that you can actually stop and reverse this endotoxemia. So it was published as a frontier paper on that journal, which was really.

Exciting to see, man. So when you hear about common causes of leaky gut, like eating too fast, eating in a stressed out state, eating these hyper hedonistic combinations of vegetable oils and sugars, the fact that you just outlined that that is the leading cause for all cause mortality, really, I mean, really makes you think about wanting to chew your food thoroughly and pay attention to gut health and not eating in a stressed out stage just as a base foundational practice.

Totally. Yeah, absolutely. And then overeating, one of the ways of inducing endotoxemia after a meal. So it's probably, it's actually called postprandial endotoxemia because they measure the highest concentration of toxins in the body and it's specifically the LPS about three to four hours after the meal. And those meals that have a very high caloric density and very high volume tend to produce a very significant amount of endotoxemia. So this is part of that overeating and the overeating and how that drives inflammation. Now what's the role of the toxin? Right, so let's talk about that for a moment. So people really wrap their head around if you're not paying attention to your, to your behaviors and your digestion and your gut health and your microbiome, what happens when the toxin leaks through. So LPS is really fascinating because it's very pervasive in the body. It can get into almost any tissue in the body. And the reason it can is because it looks like our lipid bilayer, right? So it's got this like fatty acid tail on it and it's got this carbohydrate head very similar to that lipid bilayer that makes up all our cell membranes. So it can just scoot its way into almost any cell, almost any tissue after a meal. You find LPS in deep recesses in the brain, like the hypothalamus, the frontal cortex. You find it in your liver, you find it in your joints, you Find it in your heart and your pericardium. So you find it in all these different areas of the body, and wherever it ends up, it elicits a very profound immune response. Now, the reason it elicits a profound immune response is because your immune system is designed to monitor and detect the presence of lps. Because to your immune system, the presence of LPS means that there are pathogens entering into the blood circulation. And the reason is that because LPS is made generally by gram negative bacteria, some people may have heard of gram negative bacteria, a lot of them being pathogens. So your immune system is constantly monitoring for gram negative bacteria entering into your system. And it has a protein called lbp, LPS binding protein that it makes and sends out to look for LPS throughout the body. Wherever LBP finds lps, it binds it, it activates macrophages and dendritic cells and causes those cells to go crazy and go, holy crap, we've got a bunch of gram negative bacteria in this region, like your brain, for example, your heart. And it recruits a massive amount of immune cells to that area that elicit an innate immune response. That's a cytokine like storm that a lot of people heard about during COVID So imagine these cytokine like storms happening in your brain, in your heart, in your muscles, in your joints after you eat a meal, right? If you eat really bad fats, you eat oxidized fats, you eat really high calories, you eat too fast, like you said, and just overly processed foods that have a lot of pesticides and herbicides, all of those things are driving this postprandial response. And if it keeps happening meal after meal after meal, day after day, week after week and so on, it sets up the foundation for disease, right? So this is so profound and so important, and people just don't wrap their heads around it. And this is where the importance of those basic behaviors comes from.

Well, we've established that the most likely time of my life that I'm going to die then is going to be about 4pm on Thanksgiving afternoon for a.

Lot of people, right?

That checks all those boxes. I've been learning a lot about the teeth and the jaw and the biomechanical structure of bite and also oral health. And my dentist who's been on the show before, Dr. Nico loud down in Phoenix, she does salivary enzyme analysis of some of these gram negative bacteria. Because of the association between your mouth bacteria and Alzheimer's, cardiovascular disease, et cetera, I'm assuming for many of the reasons that You've just described because these then wind up in the gut, being absorbed through the buccal membrane and winding up in the bloodstream. But could you make a case, Tina, you were talking about how the capsule can survive the gastric environment. I'm wondering if you could make a case for actually, for example, break up breaking open a couple of capsules and kind of mouthwashing to start that population in the oral environment. Have you guys ever thought about that?

Yes. So we've actually do that quite a bit in clinics and we recommend it quite a bit for people, especially during the cold and flu season, because there's a lot of association with the buccal immune response, because there's a lot of immune tissue in the soft tissue tissue in your mouth, and it upregulates protective immune response in your upper respiratory tract, in your lower respiratory tract, and so on. So the spores do play a role there. Even, even Dr. Simon Cutting, almost 15 years ago, when we first started working with him on the spores, he always recommended taking some spores, mixing it in water, swishing it in your mouth and holding it and then swallowing that. So, yeah, you're right on the right track. There's a huge advantage to doing that. I would do that kind of thing before bed and I often do it because a lot of what's happening, especially people who are mouth breathers and who tend to struggle with that issue. Right. You want to have some sort of protection in your oral cavity. I also do it a lot during cold and flu season because that really helps up regulate some of the immune response. And the spores are really good at something called quorum sensing. This is one of the ways in which it helps against gram negatives and it helps against leaky gut, is they have the ability to read other microbial signatures. So they can identify dysfunctional bacteria like enterococcus, that's a type of gram negative bacteria that tends to be found in the mouth. It can identify enterococcus and elicit cause your immune system to elicit an immune response against the presence of enterococcus. So releasing more secretory IGA that neutralizes the bacteria or even directly getting the immune system to go after that bacteria or the spores themselves will directly negate and kill off that bacteria. Right. So we've seen that and we've published a couple studies on the ability of the spores to do this. Quorum sensing, that's a really important thing. Now. You can use it on your skin, you can mix it in with lotion, you can put it on your skin. The spores are ubiquitous in the environment. And we've evolved to actually have this ongoing relationship with them. And where they're transient to our body, they show up, they clean up different systems, and then they leave again and go back into the environment.

So here's something that I'm interested in based on what Kieran was explaining about acetaminophen and liver injuries. Tina, I know you're kind of a fellow health enthusiast and do some biohacking and stuff like that. You and I have had a glass of wine before at some of these conferences and health events that we're at. Have you ever kind of tried it prior to maybe a cocktail and a glass of wine and assessed how you feel afterwards as an n equals 1 or. Have you guys seen anything done on alcohol in these specific strains?

Yeah, I mean, anecdotally, I do it all the time. You know, when I'm going to drink, I mean, I'll have. I usually have my probiotics every time at the same day. But then, you know, if I'm going to go out and I know I'm going to have a glass of wine or two, then I'll take extra for that reason. Exactly. And I also take our igg product, which is an immunoglobulin G that we don't want to distract the attention of what we're talking about today. But that's another great product that I take before. Before I'm going to engage in any alcoholic consumption.

Isn't that the same type of stuff you could find in colostrum? The IgG?

Actually, it's way more. I mean, IgG, yes. IgG is found in colostrum, but the IgG that we work with actually has 25 to 50% more IgG than most catmic colostrums out there.

Oh, wow. So for the leaky gut scenario, that could be a 1, 2 combo. If you take that and then the lactobacillus strain at the same time.

The bacillus spore strains.

The bacillus spore strains, yeah. Interesting.

And in fact, there have been. You know, one of the things we really liked about the IgG is in the condition of HIV, there's this marked thing that happens called HIV enteropathy. And this was actually a large scale published study by the NIH that showed that the biggest thing that affects HIV patients in terms of progression from being HIV positive to AIDS is the development of leaky gut. Right. And part of it is because the virus attacks the gut, and gut lining, it, of course, kills off the CD4 positive T cells, it causes CD8 cells to come in and start fighting it. And those CD8 cells are very inflammatory. So that disrupts, destroys the lining of the gut. It makes the gut very, very leaky in HIV patients. So they have leaky gut in a very profound manner. Right. So it's a very accelerated, profound model for leaky gut. It's a very similar pathology that occurs in people with just poor lifestyle choices and lots of antibiotics. And you're a common American. Right. But it's a good model to study accelerated decimation aligning of the gut. They did studies on the igg, and we worked with them with the spores and the igg, and, and what they were able to show with the igg is even in that condition of accelerated leaky gut damage that they were able to start to repair some of that lining. So the combination is a powerful one, two punch because they work a little bit differently. And it's a great way of continuous protection on the lining of the gut. And the liver thing, I've been thinking about this a lot because I do enjoy a cocktail from time to time in some really nice high end spirits. And when you think about, okay, liver protection, how do you negate some of the negative effects of alcohol? We know that a lot of the negative effects of alcohol comes from the formation of acetaldehyde. Right. And acid aldehyde can be very inflammatory. So I have two thoughts in mind. Number one is, okay, what drives some of the acetaldehyde production? There is some evidence that a dysfunctional microbiome actually produces more acid aldehyde than a more diverse microbiome. And so there is a small case to be made with early evidence that the spores may be able to help with lowering some of that acid aldehyde. Number two is the inflammation associated with the acetaldehyde and clearing it. That's where the liver comes in and that's where all the flushing and all the disturbances to the rest of the body, the spores are anti inflammatory and they're profoundly anti inflammatory. And this is a very important distinction between different types of probiotics. You know, it'd be surprising to learn that a huge number of well known probiotic strains are actually inflammatory. That's exactly what was shown. Yeah. And this is, and this is a fascinating thing where there was anecdotal evidence. And then I was able to work with researchers at University University College Cork in Cork, Ireland, one of the biggest microbiome research institutes in the world. And what they were able to show is that the vast majority of probiotic strains that are widely used, that they tested, when you take them, they elicit a huge spectrum of immune responses, including three different mechanisms of systemic inflammation. Right. So they upregulate inflammation. Your body sees these strains coming in, they don't necessarily recognize them and as a result the immune system gets fired up. Now here's the thing. For a healthy individual that is trying to ward off colds and flus and things like that, you just want your immune system kind of irritated and upregulated so that in case you encounter a virus or something like that, it deals a bit faster. That may be a benefit for the vast majority of people that are dealing with health conditions, with inflammatory conditions, it actually can make it worse.

Right, right. It'd be similar to like if you have chronic fatigue or stress issues, the same ice bath practice that might help some people develop cellular resilience and stress resilience would kind of push you overboard.

Totally. Yeah, exactly. And so when you look, when you work, and I have the pleasure of working with lots and lots of functional medicine practitioners, have a whole other thing that I do in the functional medicine world. And what I've come to find out is that a lot of holistic health functional medicine practitioners don't use any probiotics for their mast cell activation patients, their SIBO patients, their histamine intolerant patients, you know, people with all kinds of sensitivities, because these people tend to have a proclivity towards inflammation. And in their experiences, most probiotics make it worse. And now we have the answer. We go, ah, that's because most of these probiotics, you wouldn't think, but they upregulate inflammation. Now the spores are what we call in the probiotic research world silent probiotics. That means that they don't upregulate any of the pro inflammatory pathways. In fact, they upregulate the anti inflammatory pathways in the body. And that's a really, really important distinction between different probiotics. This is where I get nervous when I see kitchen sink formulas with 15 strains in them and no research behind what the immune impact is, what the microbiome impact is, and so on, because many of those, especially in their combinations, could be quite inflammatory.

So when you hear about people getting gas and bloating and sometimes a deleterious response to a probiotic, paradoxical because they thought it might help their gut, you're saying that it might not be due to what I kind of always thought was the case where I like throwing off the Microbial balance in a way that causes gastric upset, but it may actually be inducing an inflammatory response.

That's right, yeah. It could be inducing an inflammatory response in the lining of their gut. Just like a food that they may not be tolerant to would. Right. If someone's intolerant to a particular type of food, say dairy, they can't tolerate dairy while they eat dairy, they're going to get gas, bloating, loose stool and so on. Now there's a small sliver where there's certain people that might experience something called a Herxheimer reaction. Right. A die off reaction, or naturopaths will call it like a healing crisis. That is a change that's happening, that's positive, but has a negative symptom in the beginning. And normally you work through that for two or three days. But if you're taking the kitchen sink probiotics and the stuff that just doesn't have clinical studies behind the finished product and you're having a negative effect as a result of it, you could probably lean towards the idea that, okay, this is just not agreeing with my system. It's upregulating too much inflammation and it's probably not doing me any good.

The qualitative way to differentiate between the two, inflammation versus some kind of a Herxheimer reaction and die off of bad bacteria, I assume would be the length of time of the symptoms, a few days versus say several weeks. But I suppose from a quantitative standpoint, could you actually get an inflammation marker test and see if you actually had higher levels of homocysteine or interleukin or something like that. And that would give you a pretty big clue that your probiotic might have contributed to an inflammatory spike.

Yeah. So IL6 would be one that would be good to check. If you have a big spike of IL6 after using a probiotic, that generally means that you're immune system doesn't agree with that probiotic and it's not really helping you. But if you have for example, some die off like reactions, but your IL6 isn't elevated, and then on top of that you might see Interleukin 10 and Elevated, that means the probiotics actually go into work trying to induce an anti inflammatory response. But what is actually causing the discomfort is the microbes, the dysfunctional microbes that are present in your gut trying to fight against the presence of the of that probiotic. Right. This is why they call it a die off response. Like the spores for example, when they go in, one of the first things they're going to do into your gut is they'll do quorum sensing.

You mean the bachelor spores that's in the just drive stuff?

That's exactly right, yeah. The bacillus spores that are in the just thrive. When they first enter into the gut, what they do is they start reading the microbial environment. When they identify dysfunctional bacteria, they'll sit next to them and they'll produce antimicrobials or they'll elicit an immune response to try to get rid of those particular bacteria. Now those bacteria, when they're being killed off, will release a bunch of toxins. And those toxins can feel like discomfort in certain people. And so that's a die off reaction versus the probiotic coming in your immune system going, I don't know what this is, let's just attack it. And then attacking it and causing a bunch of systemic inflammation in the individual that will happen over and over again. For a probiotic that's incompatible to an individual, the die off response will go away in a day or two after those dysfunctional microbes are gone from the system.

So here's something I'm curious about. When it comes to antibiotics, some people say take a probiotic when you start an antibiotic regimen to help to replenish what you're killing off. Some people say it doesn't have any benefit. And now I'm seeing research that suggests that probiotics might actually slow down the recovery of the gut microbiome after antibiotics. Do you have any thoughts on this?

Yeah, you know, that's the, I think the Weissman Institute study that recently came out telling us that, yeah, like some of these, the kitchen sink formula type probiotics that we're talking about will actually compete with your gut flora and actually hinder your own immune cells to actually fight off the, you know, effects of the antibiotic. And so one of the things that we're so excited about with the special spores that we studied is it actually, you know, we are huge believers that you should be taking a spore based probiotic while you're on an antibiotic. We've studied this, we know that the spores actually survive the presence of an antibiotic, which is huge. They actually, you know, will not be killed off by the presence of an antibiotic. We've studied this with some of the strongest antibiotics out there. But, and we know that these are, these spores are not competing with our natural gut flora. They're actually working, you know, together with them cohesively. So. But yeah, that Weissman study was kind of Interesting, because it told us that, you know, this is what we've been preaching for years. You know, we don't want to be, we have to be careful when you're taking these, you know, multi strain probiotics without a study on the finished product.

So the study that showed that probiotics could hinder the recovery from antibiotics from a gut microbiome standpoint, they were using like a multi strain formulation. Was it like an off the shelf or were they just using a random set of strains that they had at Wiseman Lab, or do, you know, so.

So what they did is they actually bought strains from a, from a data bank that are commonly used probiotic strains. So, you know, your acidophilus and those types of strains that are typically found in a probiotic, and they assembled a formulation that mimicked your average multi strain probiotic on the marketplace. They didn't want to go and buy any given commercial product. What they were trying to do is kind of create one that was a representation of your typical generic probiotic combination. Now, what's really important to note here is, and this particular study tells a really important story about understanding why probiotics are different. Right? So when you think about a probiotic strain or things that people call probiotic strains, there are really two distinctions. Number one is, is it a resident strain naturally? Is it naturally a resident strain to the gut, or is it a transient strain to the gut? Now, probiotics in general should be transient strains, because transient strains have a way of coming in, interacting with the microbiome, with the immune system, doing positive things and then leaving. Because your job is not to, say, stay there and take up space. Right. Now, when you take probiotics that are actually resident strains and try to put them into your system, they're going to go in and compete with your other resident strains.

Yeah, that makes, it'd be like having a plumber who I wanted to come over and clean my toilet and then leave when they're done, versus them setting up shop in the master bedroom closet with a sleeping bag. And it vastly changed my lifestyle, one versus the other.

That's exactly right. Yeah, that's exactly right. And the thing about it is that what happens to the gut microbiome when you take an antibiotic is with the first dose of the antibiotic, within about 90 minutes or so, it knocks down almost all the strains in your gut microbiome down to just a few cells of each strain. Right. So the volume of bacteria drops down quite dramatically, which means there's now a lot of real estate open for microbes to start taking over binding sites and campsites and so on. Now the bacteria start to grow back, right? That's, that's the beauty of bacteria is you can't kill them off completely. They're going to start to grow back. But what grows back and in what proportion is where you start to see the dysfunction. Now what happens is if you, if those get knocked out, then you take 15 billion of these other resident strains from other sources, those 15 billion are going to start competing for binding sites with your own resident strains that are trying to grow back. That's where we see the big problem. That's why to me, when I think about this as a microbiologist, I'm like, the best probiotics and the safest ones are always going to be transient strains because that's actually how we interact with microbes in the natural environment. All of the microbes we come across in the natural environment, whether it's in the dirt or, you know, rivers and streams, or foods that we forage for and pick and so on, or microbes that we get from each other, that we interact with, are going to be transient in your system. They're going to go in, they're going to be that plumber, they're going to fix a thing or two and then they're going to leave when they're done, right? That's really what you want at the end of the day.

Now we are able now to test our gut. You know, I recently did a Genova three day stool panel which kind of tells you parasites and yeast and fungus and some bacterial balance. There are other companies like Viome, for example, that are doing these bacterial profiles of the biome. Why can't you look at the results of a test like that and literally customize the type of bacteria that you're replenishing based on what each person's unique biome is? And based on that, how do you know that one specific strain is going to be good or bad for just the general population? Does that make sense?

Yeah. Yeah. So that, that is the, the ultimate goal of microbiome science is can we get to a place where we can look at an individual's microbiome and understand what they need specifically? Now, we're not there yet, and it's for this reason. The reason is that at the species level, right? So if you look at bacteria, we've got, you know, everything that lives starts with kingdom, order and all that. And everyone knows that there's genus and species, right? So just for people that may not be familiar. So if you take Lactobacillus, acidophilus, or in our case, bacillus subtilis, the lactobacillus or the bacillus is the genus, and then the specific species is the subtilis or acidophilus, right? So in humans, we're Homo sapiens sapiens, so we're the same almost genus and species. Now, what we don't know yet is why at the species level, we are all vastly different in our microbiomes. You and I, Ben, could have maybe 25% similarity at the species level in our microbiomes, and yet we may have 98% the same functionality out of our microbiomes. Now, the reason for that is because there's a lot of functional redundancies among bacteria, right? Like I may have a certain set of bacteria that's producing short chain fatty acids for me, and it's doing it at the right levels. You may have a slightly different set of bacteria, but they're still producing short chain fatty acids. So both of us have preserved that function of producing short chain fatty acids. You just have different players that are doing it than me. Right? So at the species level, it becomes very complicated to understand how to modulate the microbiome. So when you look at the microbiome and you look at function rather than species population, that's where we can start to make changes. Now, the other problem is a given individual's microbiome can have up to 1,000, 2,000 species in it. The vast majority of those species have never really been isolated well, and they're not available from a commercial standpoint to repopulate the gut, right? So most probiotics, as people are familiar with, have bifidobacteria, lactobacillus as genuses. And then in our case, we have Bacillus. Just looking at those, that makes up 99% of the probiotics out there. That's only three genuses out of thousands that could exist in an individual's gut, right? So if we look at an individual's gut and we go, oh, my God, they're missing, you know, this particular genus. Well, there's no source of that genus out there to repress, to replenish that individual's gut. So then you have to really look at how do we upregulate the endogenous level of that bacteria. This is where transient microbes come into play. As it turns out, one of the things that the bacillus spores can do is they can naturally help. Some of the underrepresented genuses and species in the gut replenish themselves by producing compounds that those particular bacteria feed off of. Right. So we saw, we did a study where we published a study showing that when you add bacillus endospores to your gut microbiome, it increases the diversity of all species by almost 30%. Right. So species that were there at such low levels that we could barely detect them, they're now flourishing. Right. We've all heard of Akkermansia. Akkermansia is becoming so important now. And people are starting to understand the benefits of Akkermansia, your endogenous Akkermansia especially. We did a study where we showed that we can add Bacillus subtilis in and the just thrive probiotic combination. And in individuals where Akkermansia was not detectable because it was at such low levels, we were able to see a thousand fold increase in as little as three weeks.

So what do you think would happen if I started breaking open a couple of the just thrive bacillus spores and putting them into my yogurt before I ferment the yogurt? Do you think it would help with the growth of the other bacterial strains in the yogurt?

It will, yeah. And in fact, bacillus is used quite a bit for fermentation. Part of it is because bacillus will acidify the environment. They will produce lactic acid. The acidified components will actually help some of the beneficial bacteria grow and prevent the growth of yeast and mold and so on. They will also produce a number of peptides. Peptides. And these peptides actually help other beneficial bacteria grow. That's one of the ways in which they do it in the gut. So we had for a while some recipes of fermenting fruits, for example, with the bacillus. One of the things you can do that's simple is take a mason jar and fill the bottom third of the mason jar with any kind of fruit that has sugar in it. So pineapples, berries, and so on. And then the rest of it with water, you open a capsule of just thrive, you put it in the mason jar, stir it up and then seal it shut and then leave it on your, on your kitchen counter for three or four days. You'll start to see some bubbles forming in there and you're basically getting a fermented fruit juice that now has even higher nutritional value because there are organic acids, there are peptides or all kinds of wonderful things in there now. And it tastes good. Right. So you can actually do that as well as a side.

You might have just saved me a bunch of money on my water kefir grains for making like countertop fizzy water kefir. I'm gonna have to try this, Tina. You guys need to do a cookbook too.

Yeah, well, we do send out recipes on our blog.

Oh, I didn't realize that. Okay, now kind of a logistical question. You know, it's like 100 degrees outside right now. What happens if I order from your company? It arrives and like the bottle's hot.

Yeah, it's. That's not a problem at all. These spores are so hardy that they're able to withstand. We've tested them up to 450. They will withstand heat of up to 455 degrees, if not hotter. But we actually tested it at 455 degrees, so that's not a problem. We get that question all the time. But you could open the capsules and mix them with food and bake with them. You know, if your kids are picky or a spouse is picky or somebody doesn't want to take them, you could actually bake with them. So they are. That's how hardy they are. That's the same ability that they have to survive the presence of an antibiotic. They actually, that strike shell on them actually allows them to survive the high temperatures and low temperatures as well.

That's actually going to surprise a lot of people, including me. That you can get them that hot. That's actually pretty cool.

You might think this is interesting, Ben. The oldest bacillus spore that's been found was found in a cave in California. So if people aren't familiar, what's happening is that we're approaching this post antibiotic world because of overuse of antibiotics. A lot of the pathogens have developed resistance to antibiotics, and that's a very scary thing if you get, for example, a MRSA infection where, where no, no antibiotics can help you. So what researchers are doing is they're going deep into caves that have never been explored, looking for bacteria that may make a unique antibiotic that we haven't even thought of to be able to try utilize it to create the next generation antibiotics. Because again, all antibiotics originally came from yeast, mold and other bacteria. So they were going in these caves in Southern California and they found these salt crystals and then they were able to melt down salt crystals and isolate Bacillus endospores from the salt crystals and they were still alive. Those microbes were 250 million years old sitting there right 250 million years old, still alive. And they've pulled out bacillus endospores from glacial ice cores that were formed 40, 50 million years old. And there's a study showing that bacillus subtilis, one of our key strains that are in the formulation, can survive in the vacuum of outer space for over seven years. And maybe one of the earliest forms of life on Earth, because there's this concept of panspermia, where the fundamental building blocks of cells were seeded on Earth during the bombardment period from meteors and all from outer space, because they find proteins and amino acids and all that on meteors. And so they looked at microbes that exist today that could have made a journey on a meteorite across from, say, Mars and landed on Earth. And they found that bacillus subtilis is one of the few that could have made that interstellar journey. So these are phenomenal organisms, right? And they're all around us. And you just have. In our case, we kept thinking we're just smart enough to figure out what nature already has for us. We're not trying to recreate nature. We just have to know what she has for us and how to utilize it and how to put it back into our system.

Hey, you talked about, for the oral microbiome, maybe putting a little bit of a broken up capsule and swishing around the mouth prior to sleep. But could probiotics help with sleep, do you think? Are these specific spores help with sleep?

Yeah, absolutely. I mean, we know that there's the gut brain access and so, so much of what's going on in your brain is a affected by what's going on in your gut. So we see that all the time. So many people will come to the product because of the common digestive reasons, you know, gas, bloating, diarrhea, constipation. And then, you know, three months into it, they're like, I'm sleeping better. Oh, I have more energy, or I better weight management. We see that a lot too. But it just makes so much sense. If you're going to the bathroom more regularly and you're getting rid of toxins, and if you're taking care of all those neurotransmitters, neurotransmitters that are in your gut. 90% of our serotonin is produced in our gut. GABA is produced in our gut. Dopamine is produced in our gut. So all of these important neurotransmitters are helping us. And definitely we see that all the time. People have improved sleep from it didn't.

You send me something that says calm on the label? Did you just put other stuff in it that also helps with sleep?

Yes. So our Just Calm product is a psychobiotic. So a psychobiotic, it basically is the friendly background bacteria that's supporting that gut brain access. And that's a strain called bifidolongum 1714 that has eight clinical trials on it about how it basically has shown to balance out cortisol. So lowering cortisol levels, lowering your perception of stress, even changing your brainwave activity. So putting you more in that theta wave state where you're calmer more in that meditative state, not where you're, you can't function, but it's just where you're more focused. And so the studies on that product are amazing. And obviously we've had a ton of success with it because we've seen some great results.

Well, this is super interesting. You know, I know there's a lot of research studies and a lot of product information that you guys have on Just Thrive. I gotta check out these recipes, by the way. I had no clue you were putting those out. But what I'm gonna do is for the show notes, they're gonna be for everybody listening in it.

And just, you know, give yourself grace along the way as you're going through your gut healing journey.

One of the things I want to say is that gut health, and I think most people listening are probably in tune with this, but gut health is so paramount to overall health and wellness and longevity. When you think about gut health and what is the healthiest marker of your microbiome, based on all the studies that have been published out there over the last 10 years, and we're talking probably two or 300,000 studies on the microbiome the really key foundational thing is diversity in the microbiome. The higher the diversity of your gut microbiome, the longer you live, the more, the more resilient you are to disease. The more cocktails you can enjoy without all the negative effects, the better your muscles function, the better you perform in every single way. And so maintaining and increasing diversity is a critical step in having really true foundational health. And the thing is, when you look at all of these listed known healthy behaviors like eating healthy foods, being outside, exercise, meditation, all of these things have been shown to actually increase the diversity of your gut microbiome. Another thing that really helps with maintaining and increasing diversity is taking the right probiotic. But you need a probiotic that has the ability to impact the rest of the microbiome, is transient in that way and is designed by nature to improve the diversity of your gut microbiome. That's where these bacillus endosporms. So we're super excited to have been working with these for like 10 years now and we'll continue to work with them and put out more studies and more information.

That's awesome. If you heard that part about diversity and you're listening in, that means if your idea of your vegetable intake is the all too common cucumber, carrot, tomato, lettuce, and maybe throw in some chicken and rice, then read my cookbooks or branch out wide variety of herbs, spices, fruits, vegetables, fermented foods, meats, and that's going to back up the use of these type of spores that we've talked about.
