Full Transcript:

Dr. Ted Achacoso (00:01): If your autonomic nervous system is in a chronic fight or flight state, your cells sense danger and lock themselves in cell danger response one. In this state, they physically shut down their mitochondria and stop energy production to defend themselves against a perceived threat. You can throw thousands of dollars of premium supplements, NAD precursors, and heavy stimulants at them, but they won't use them. It's like pouring premium fuel into a car with a seized engine. You cannot out-supplement a cell that thinks it is under attack. We have to signal safety first.

Dr. Allen Bookatz (00:34): This is the Health Optimization Medicine Podcast. Around the table today, your clinical team. We have our resident naturopath, Jodi Duval. We have the founder of Health Optimization Medicine and Practice, Dr. Ted Achacoso, and me, your emergency medicine, acute care, and health optimization doctor, Dr. Allen Bookatz. We're chasing one question: why can't you out-supplement a dysregulated nervous system? Over the next 25 minutes, you'll get the mechanisms, the protocol, and the one thing almost everybody gets wrong about it. Let's get into it.

Jodi Duval (01:02): Yeah.

Jodi Duval (01:06): Thank you, Dr. Allen Bookatz. Now let's frame this clearly. We are seeing an absolute epidemic of over-quantification and supplement fatigue. I sure see it in my practice. I see spreadsheets and spreadsheets full of it. People are taking 50 pills a day, running on a continuous cycle of ice baths, intense workouts, and strict fasts, all while wearing multiple trackers. You know, some people have three or four trackers on at one time. Yet we feel more exhausted, their sleep scores are plummeting, and their anxiety is through the roof. They are trying to force their biology to be resilient, screaming that you must comply, and completely ignoring the fact that the autonomic nervous system is screaming danger. So Dr. Allen Bookatz, in your practice, you must see an extreme end of this dysregulation constantly.

Dr. Allen Bookatz (02:00): I do, Jodi, and more frequently than people would think. And it's not just from the typical type of emergencies, you know, in the ER. I mean, I see people who come in from their primary care doctor from years being on paper completely fine. Their blood work is clean, they've had CTs, X-rays, MRIs. Everything's normal, brain MRIs, and yet they're still in real distress. They can't sleep, they have brain fog, and they're just nervous wrecks. Panic, palpitations, fatigue. Now, functionally, like they are falling apart. This is not someone who is well. This is not someone who's healthy. And this is not someone who's optimized. And conventional medicine, unfortunately, just has nothing for them. Because our training in conventional medicine, and I'm still in it, we are trained to hunt for organ pathology, not look for cellular or autonomic imbalances. So when those same patients try to biohack their way out with stimulants and aggressive stressors, they don't really climb out, they just crash harder.

Dr. Ted Achacoso (02:36): Mm-hmm.

Dr. Allen Bookatz (02:55): So when those same patients try to biohack their way out with stimulants and aggressive stressors, they don't really climb out, they just crash harder.

Dr. Ted Achacoso (03:00): And this brings us to the core of the issue, Dr. Allen Bookatz. Many biohackers still unwittingly adopt the pathogenic mindset of conventional medicine, treating symptoms with a pill or a forced protocol. They treat exhaustion with mitochondrial supplements and focus issues with heavy stimulants. But they are asking the wrong question. They're asking, what supplement can I take to fix this? When they should be asking, why does my cell feel unsafe in the first place? Aligning our understanding of cellular safety and autonomic regulation is where it must start. Remember that evolutionarily, you know, we are built for survival and reproduction, and the cell is simply trying to survive.

Jodi Duval (03:46): So this $64,000 clinical question of the day is then why does biohacking fail when you ignore their autonomic nervous system's danger signals? So let's dive into the science, the mechanism of how autonomic dysregulation literally locks down cellular function. So, Dr. Ted, let's unpack the biochemistry, which we all love. That's why we're here. When we are chronically stressed, whether that is stress of a physiological, chemical, or physical nature, how does the autonomic state translate into cellular lockdown? What's the actual mechanism?

Dr. Ted Achacoso (04:23): To understand this, we must look at the work of Dr. Robert Naviaux on the cell danger response, or CDR. The mitochondrion is not merely a powerhouse that grinds out ATP, it is the ultimate environmental sensor. Under normal safe conditions, the mitochondria produce ATP inside the cell to power cellular functions. However, when the autonomic nervous system is in a sympathetic fight or flight state, the brain releases norepinephrine and epinephrine and the adrenals release cortisol. This autonomic alarm state changes the biophysical properties of the cell membrane.

Dr. Allen Bookatz (05:02): Yep. How does how does that physical membrane change alter mitochondrial behavior, Ted?

Dr. Ted Achacoso (05:18): When the sympathetic nervous system fires, cell membranes stiffen to prevent viral entry and retain resources. This membrane stiffening causes the mitochondrion to release ATP outside of the cell into the extracellular space. This extracellular ATP, or eATP, acts as a potent danger-associated molecular pattern, or DAMP. It binds to purinergic receptors and neighboring cells, signaling a state of immediate threat. This triggers a cell danger response stage 1, or CDR1. In CDR-1, the cell halts aerobic respiration, downregulates mitochondrial energy production, and shifts to anaerobic glycolysis. It diverts oxygen and resources away from energy production and towards defense and inflammatory signaling.

Jodi Duval (06:02): And this is a massive point. So when we have the autonomic nervous system and when it's dysregulated, the cell is literally locked in a defensive posture. It's holding on tight like a boxer. So in CDR1, the cell cannot use standard nutrients for energy because its metabolic machinery is deliberately offline. And this is why throwing NAD precursors or CoQ10 at the cell fails. And the cellular receptors and metabolic pathways are downregulated to protect the cell from what it perceives as an active attack. We need to be able to first pull down the defenses, and then supplementation will be able to work so much better.

Dr. Ted Achacoso (06:45): Exactly, Jodi. You can infuse all the nutrients you want, but if the purinergic receptors are constantly activated by extracellular ATP, the cell remains in defense mode. This is beautifully demonstrated in a recent study published in Molecular Psychiatry in February of 2026, where the researchers found that psychological distress and autonomic anxiety directly trigger the release of circulating mitochondrial DNA and other damage markers into the bloodstream, locking cells in a chronic state of inflammatory defense. This is clinical validation of what HOMe has been teaching for years. Mental and autonomic state directly dictates mitochondrial safety and cellular health.

Dr. Allen Bookatz (07:25): Ted, this study is a really big deal. You know, in the acute care side, it explains something that I see quite frequently, and that's that people under heavy psychological stressors show up with physical signs of mitochondrial dysfunction. So that fatigue and that brain fog, it's not just that they have something psychological going on, but their cells are literally being starved of energy because their nervous system is screaming danger, holding the mitochondria now offline. So it isn't showing up necessarily in a typical organ pathology and organ disease that we would look for. It's this kind of functional metabolic shutdown of sorts that's triggered by some type of safety mismatch.

Jodi Duval (08:08): This is what absolutely fascinates me because in clinical practice we can see this in real time. You've got clients coming in, and as a naturopath, I see this reflected in the gut and the symptoms that I see clients complaining of when they walk in the door. The vagus nerve is this bi-directional superhighway, and I talk about it with all of them quite a lot. About 80% of its fibers are sensory afferents going from the gut to the brain. So when the autonomic nervous system is sympathetically dominant, then this vagal nerve or vagal tone drops. This halts gut motility, you get constipated, it reduces your hydrochloric acid, you can't break down food effectively, you start burping a lot, and digestive enzyme secretion goes down. This triggers local gut immune activation, so your intolerances can increase as well. This leads to dysbiosis, localized inflammation, and increased intestinal permeability. The bacterial endotoxins, then, like the lipopolysaccharides, can enter the portal circulation and then further activate the purinergic receptors, reinforcing the cell danger response, further shutting down the cells and the mitochondria. You cannot heal the gut or optimize neurotransmitter synthesis if the vagal nerve is silent or toned down.

Dr. Ted Achacoso (09:27): And this is where we must draw a sharp contrast between Health Optimization Medicine and Practice, or HOMeHOPe, and functional medicine. Functional medicine often focuses on finding the root causes of a disease, which usually leads them to prescribe a complex stack of supplements to treat specific gut markers or hormone deficiencies. But root cause is not enough if the root question is still disease. HOMeHOPe is health-centered, not disease-centered. Pathogenesis is the root causes of disease. Salutogenesis is the root causes of health. We do not prescribe lifestyle or supplements from a slogan, we prescribe them from cellular and autonomic data to signal safety and restore cell coherency.

Dr. Scott Sherr (10:07): Pardon the interruption. This episode is brought to you by the 4th annual Health Optimization Medicine and Practice Conference happening October 2nd and 3rd in Chicago, Illinois at the Drake Hotel. You are all cordially invited to something that's not a typical conference. This is truly a community and you'll feel that the moment you walk in. This is not wellness aesthetics, not disease management dressed up in optimization language. This is actual rigorous, measurable, deeply human health optimization. And it's a small group. Only 150 seats are available. And we've already sold out a lot of these. It's going to be an intimate gathering. If you want your ticket, you need to get it soon.

I hope to see you there. Take care.

Jodi Duval (11:27): And this is the pivot here. So if we cannot out-supplement a dysregulated nervous system, what do we do? How do we actually establish autonomic and cellular safety? Biggest question of the day. So what is the HOMeHOPe trained practitioner or doctor's protocol?

Dr. Ted Achacoso (11:40): Yes, first of all, we teach our students to be experts at clinical cell danger response management, right? The protocol must follow a strict logical sequence and it begins with chronobiology. Our master's circadian clock or suprachiasmatic nucleus coordinates autonomic balance. The most profound evolutionarily conserved signal of environmental safety we can give our nervous system is morning light. The protocol requires fifteen to twenty minutes of direct early morning sunlight exposure to the eyes without sunglasses, ideally within an hour of waking. This light activates melanopsin-expressing retinal ganglion cells, which project directly to the suprachiasmatic nucleus, suppressing melatonin and setting a precise sympathetic to parasympathetic transition window. This circadian anchor is the absolute foundation of autonomic safety, and we know that most accidents occur actually at twilight because dark signals danger. So in the morning it signals safety because now we can see as we eat, we are a very visual species.

Dr. Allen Bookatz (12:47): So Ted, once that circadian anchor is now established by getting up and seeing sunlight, well how do we now actively upregulate the parasympathetic activity?

Dr. Ted Achacoso (13:00): Well, as a gadgeteer, a nifty device hack would be a transcutaneous auricular vagus stimulation or taVNS. The auricular branch of the vagus nerve innervates the cymba conchae of the outer ear, right? By applying a low frequency electrical stimulation to the area, we can directly stimulate the vagal afferents, activating the cholinergic anti-inflammatory pathway. This signals the spleen and the gut immune system to downregulate inflammatory cytokine production and down-regulates purinergic danger signaling, allowing cells to exit CDR1 and advance into the recovery phase CDR2. This is a direct biophysical method of signaling autonomic safety. Or without any such device, as most of us don't, you can use your pinky in that area of the ear to massage it. Or another way would be to sing, right, Dr. Allen Bookatz? Even if you can't carry a tune. And for men, erection is also a parasympathetic thing.

Jodi Duval (13:55): Well, that's one thing I miss out on then. One way to do it. We don't always need extra gadgets, do we, Dr. Ted? We can actually do it with our erections and our pinky. So what about biochemistry, Dr. Allen Bookatz? How do we support this parasympathetic shift using bioactive molecules?

Dr. Allen Bookatz (14:19): Well, we start with something we don't talk about often enough. We need to support the GABA system. GABA is the brain's main brake. It's the primary inhibitory neurotransmitter in the central nervous system. So when you're locked in a sympathetic loop, or as Dr. Sherr would say, the sympathetic spiral of doom, the opposite, right, is running the show: glutamate. And glutamate you can consider is considered to be the accelerator when it's in excess. So when we reach for calming positive allosteric GABA modulators, I know it's a handful, things like pulsed Kava extract or L-theanine, those essentially help your own GABA bind just a little bit better and they help quiet that central alarm that's going off continuously. And that drops the sympathetic drive and that lets the body settle into a more restorative, parasympathetic state. And we don't guess at it. We actually test this. We run clinical metabolomics, we look at organic acids and we make sure that the cofactors that GABA actually depends on, like active vitamin B6 and magnesium and taurine, and that they are exactly where they need to be. Otherwise you're not gonna get anywhere.

Dr. Ted Achacoso (15:32): And how do we track this protocol success? What biomarkers are we looking at?

Jodi Duval (15:38): Well, that would be HRV, Dr. Ted. So we track heart rate variability. And it's a surrogate marker of vagal tone and parasympathetic activity. But we have to track it with awareness. As we said before, you know, we can over-track and we have way too much data. So we have to be intuitive with our bodies as well, not just rely on the data that we're seeing. So we have to look at this in not an anxiety-inducing form. We instruct patients and clients to measure their HRV using wearable trackers once a day. So for me, I'll wake up in the morning and check my HRV on my Oura ring and I'll go, okay, how well did I do yesterday? And how did I sleep? What was it like? So, you know, at the same time we then focus on the weekly, monthly trends. So we're looking at data over time rather than those immediate daily fluctuations. And they do run in patterns, you can see them coming up slowly or going down slowly, and that's when you can take more action. If clients are obsessing over daily scores, they trigger the sympathetic anxiety as we've talked about. And this is defeating the purpose. You know, clients are looking at trying to have confidence in looking after themselves, and if they're only seeing the HRV going down or comparing it to someone else, it's going to bring out more anxiety for them. So we also run the clinical metabolomics to measure circulating markers of mitochondrial function. And so we can actually see if there is this cellular component that also is driving down the HRV. So lactate to pyruvate ratios, lipid peroxides or oxidative stress. And this can confirm that the mitochondria are successfully exiting defense mode and returning back to aerobic respiration.

Dr. Allen Bookatz (17:37): All right. Jodi, thank you for that wonderful overview. For those of you that are listening and say, I'm looking for something practical. What do I need to do? I'm gonna let Dr. Ted and Dr. Jodi worry about the metabolites and the organic acids and coming up with a targeted regimen for me. But what can we do? So this is gonna be your do this on Monday if you find that you're running on empty and feeling dysregulated. Do this sequence. To review, we are going to number one, circadian anchor. So get 15 to 20 minutes of real morning sunlight within an hour of wakening. No sunglasses. And do this. This should be the first light that you see the day. Not your screen, not your bathroom. Just get up and get outside.

Dr. Ted Achacoso (18:23): And if you can't do this, you actually can buy yourself a vitamin D lamp and expose yourself to it. It could be a good circadian anchor.

Dr. Allen Bookatz (18:32): Very good. Number two, vagal upregulation. Fifteen minutes of some type of vagal nerve stimulation. It can be the tragus auricular vagal nerve stimulator, it can be meditation, it can be breath work, morning and evening, doing this consistently, giving your body that signal to switch on that cholinergic anti-inflammatory pathway. If you don't have a device, that's okay. You can massage the cymba of your ear which is basically the part that is connected to your face, the closest part, and you can hold that with your pinky. And if you don't want to do that you can just sing or hum and it doesn't matter whether you can carry a tune.

Dr. Ted Achacoso (18:40): you know you can carry a tune, not just the right notes.

Jodi Duval (18:46): Doesn't sound in tune.

Dr. Allen Bookatz (18:50): Especially if I'm the one listening to it. Number three, GABA support. So pulsing L-theanine or some type of high-quality Kava extract in your high stress windows to create central safety and dial in your magnesium based on your actual cell data. And number four, metric detox. So if your tracker is stressing you out, just put it in a drawer for a week, let that subjective feeling and baseline safety lead.

Dr. Ted Achacoso (18:52): Yeah.

Dr. Allen Bookatz (19:20): Okay, now let's pressure test our own thesis here. I'll steelman the hardline biohacker, and the old school athletic camp. A serious critic would say stress is the whole point, isn't it? It's the prerequisite that we have for adaptation. That's hormesis. You want stronger muscles, then you gotta tear them hard under heavy load. If you want mitochondrial biogenesis, then you gotta hit the cell with hypoxic stressors. With strict fasting, extreme cold plunging. And from that view, right, all this soft nervous system work, the vagal stimulation, the breath work, anchoring, light, right? That is just meditation wearing a lab coat. It doesn't build real rugged resilience. You can't comfort your way to adaptation. That's not how we survive. That's not how we become hearty. And you can't really replace that hard adaptation forcing stimuli with just a sunrise and hum.

Jodi Duval (20:17): That is an exceptionally strong argument, Dr. Allen Bookatz. So maybe we completely agree with the principle of hormesis. However, hormetic stresses are indeed the primary drivers of cellular biogenesis and mitochondrial capacity. But Dr. Ted, take us away.

Dr. Ted Achacoso (20:37): But here's a crucial difference that the critic is missing. Hormesis is only hormetic if the cell has energy capacity to adapt. Thus, if a cell is already locked in a chronic cell danger response due to baseline autonomic dysregulation, its mitochondria are offline and its energy reserves are depleted. If you subject an already threatened cell to an additional severe physiological stressor, like an intense ice bath, a 48-hour fast, or heavy training, the cell does not interpret this as a hormetic trigger for growth. It interprets it as an additional active threat. This pushes the cell deeper into CDR1, worsens inflammation of the cells, accelerates mitochondrial damage, and eventually leads to systemic burnout and chronic fatigue. Autonomic and cellular safety is the absolute prerequisite for hormesis. You must signal safety to the cell before you can ask it to adapt.

Dr. Allen Bookatz (21:31): Okay, fine. That's a, as usual, a brilliant reframing, Ted. I guess it's the difference, right, between whipping an exhausted horse and saying, 'Go, go, keep running,' and letting it rest, giving it some food. If the horse is exhausted, then whipping it might get it to run maybe ten, five feet before it collapses again. But if you haven't given it energy rest, then you've just accelerated it to its own end. So I guess in clinical terms, though, we must establish this autonomic safety first, allowing the cells to advance. What I'm hearing is they need to advance from the CDR2 state and CDR3 state, restoring their baseline energy reserves. And then only then can we introduce carefully calibrated pulsed hormetic stressors that we can then build upon a strong foundation to build true rugged resilience.

Dr. Ted Achacoso (22:32): Yes, again, this is a take on our evolutionary fitness function, right? The cell wants to survive first. So it will ask, am I safe to survive? Because it's the first thing. Is someone gonna kill me? Then that's the first thing that it's gonna address, right? And so you must think of it that way. It's not only true for us as a person, which is an ecosystem of cells, it's true for the cell too. It's like, well, am I safe to survive? If I'm in danger, no, let me address the danger first, because otherwise I'll be dead, right?

Dr. Allen Bookatz (23:04): So you're saying the target is not just longer life, it's maybe longer access to peak optimized biology?

Dr. Ted Achacoso (23:10): Absolutely.

Dr. Allen Bookatz (23:12): Okay, well let's deliver our take home three standalone takeaways. Jodi, what is yours?

Jodi Duval (23:25): So lifestyle prescription becomes precision medicine only when cellular and autonomic data guide the prescription. So we can stop guessing with a generic stack of 50 supplements based on a wellness slogan or your best algorithm on social media, which it happens a lot. Establish this foundational parasympathetic safety and gut immune coherence first. Let the metabolic markers guide your nutrition and behaviour and this can take the stress away from that guessing anyway.

Dr. Allen Bookatz (24:02): So good. Mine is your wearables should be used to track trends, not trigger your daily anxiety. So if checking your sleep score or your HRV in the morning is causing you any type of stress, then you are suffering from orthosomnia and you're driving your nervous system into sympathetic dominance. So put that tracker away, anchor your circadian rhythm with morning sunlight, and learn to listen to your body's internal safety signals.

Dr. Ted Achacoso (24:29): Yeah, call it orthosomnia nervosa and it becomes more ominous.

Dr. Allen Bookatz (24:31): Nervosa.

Dr. Ted Achacoso (24:33): Well, mine, Dr. Allen Bookatz. Mine is you cannot out-supplement a cell that thinks it is under attack. If your autonomic nervous system is dysregulated, your mitochondria are locked in the defensive posture, and they physically cannot use nutrients for energy production. Prioritize circadian anchoring, vagal stimulation, and GABAergic safety protocols before attempting to optimize cellular biochemistry. Safety must precede optimization. And in fact, safety is part of optimization. To conclude, we must remember that Health Optimization Medicine and Practice, or HOMeHOPe, is fundamentally built on principles of salutogenesis and cell coherency. While conventional medicine is highly successful at diagnosing and treating acute organ pathogenesis, as Dr. Allen Bookatz here is an expert of doing, it completely ignores the functional metabolic matrix of health. By utilizing clinical metabolomics, chronobiology, and autonomic safety protocols, we do not treat disease. We detect and correct imbalances. At the cellular and nervous system level, we signal environmental and physiological safety to the body, allowing our cells to exit defensive dangerous states and return to a coherent, self-healing, and optimized physiologic state. This is the future of healthcare, and we're doing it now in Health Optimization Medicine and Practice.

Dr. Allen Bookatz (25:58): Well, there you've heard it, folks, from the Dr. Ted himself. That is our show for today. If you want to master this clinical framework and learn how to detect and correct these foundational cellular and autonomic imbalances, then we have a complete science-backed curriculum designed for both physicians and non-physician healthcare practitioners. So head over to our website at homehope.org. Join our global movement of clinicians defining the standard of care in health, not disease. Stay curious and we will see you next week.

Jodi Duval (26:32): Bye.

Dr. Ted Achacoso (26:35): That's a wrap.

Dr. Allen Bookatz (26:37): Well done.

Jodi Duval (26:37): Well.
