The Hidden Switch: Why Long COVID Lingers and How to Restart the System 5
The final domino in long COVID recovery is integration. By now it is clear that no single pill, peptide, or supplement can resolve the condition. The problem is systemic a stalled cell danger response that traps immune, mitochondrial, vascular, and autonomic systems in alarm mode. The solution is not to throw everything at once but to restore order through a phased, feedback-driven protocol. Sequencing matters more than stacking. Just as you would not rebuild a storm-damaged city by opening shops before fixing power lines, recovery requires careful order: stabilize first, repair second, retrain third. Phase one is the redox reset and immune modulation stage. The goal here is to calm the storm and stabilize energy so the system is ready to heal. This is where Kenetik Pro becomes uniquely powerful. As a ketone monoester, it rapidly raises circulating beta-hydroxybutyrate, giving mitochondria an immediate alternative fuel. Ketones bypass damaged Complex I and glycolysis bottlenecks, providing steady ATP even when glucose metabolism is impaired. This takes pressure off fragile mitochondria, lowers lactate buildup, and gives patients the first taste of metabolic stability. Beyond energy, ketones act as signaling molecules suppressing the NLRP3 inflammasome, reducing oxidative stress, and stimulating mitochondrial biogenesis through PGC-1α. In practice, Kenetik Pro is like plugging in a backup generator during a blackout: the lights come back on, even while the grid is still being repaired. This metabolic cushion makes all other Phase 1 interventions more effective. Alongside Kenetik Pro, mitochondrial-targeted peptides like SS-31 stabilize cardiolipin and reduce electron leak. Thymic peptides such as TA-1 help restore T cell balance. KPV and resolvins modulate mast cells and push inflammation toward resolution. Antioxidant stacks with NAC, glycine, and glutathione rebuild redox buffering. Methylene blue also fits into this phase, but its timing is particularly relevant. While it can act as an electron bridge across damaged complexes, methylene blue also inhibits nitric oxide synthase. That means it can block endothelial nitric oxide production. In situations where NO is excessively high such as during oxidative stress surges, vasoplegia, or inflammatory storms this can be useful to prevent further vascular damage. But nitric oxide is not purely harmful; the immune system requires inducible nitric oxide (iNOS) to kill pathogens and regulate immune responses. If methylene blue is overused or given at the wrong point, it can blunt immune clearance and stall recovery. The art is in using it as a short-term stabilizer, not a continuous intervention. Think of it as temporarily shutting off a fire hydrant when the streets are already flooded, but making sure not to cut water supply to the firefighters who still need it.
@Anthony Castore absolutely agree
Thank you! This is a great step by step protocol, very helpful in organizing treatment plan!
The Hidden Switch: Why Long COVID Lingers and How to Restart the System Part 4
One of the least appreciated but most critical aspects of long COVID is endothelial dysfunction. The endothelium lines every blood vessel, acting as a dynamic interface between blood and tissue. In healthy states, it regulates vascular tone, prevents clot formation, and coordinates nutrient delivery. In long haulers, endothelial cells remain injured and inflamed, leading to microclot formation, impaired oxygen delivery, and disrupted autonomic signaling. This explains why so many symptoms—from shortness of breath to brain fog to rapid heart rate—can be traced back to vascular chaos. Microclots are a defining feature. These are not the large clots that cause strokes or pulmonary emboli but tiny fibrin-rich clots resistant to normal breakdown. They trap proteins, inflammatory molecules, and even spike fragments, acting as persistent irritants in the circulation. By blocking capillary beds, they reduce oxygen delivery to tissues, creating hypoxia at the cellular level. This is one reason why long haulers feel exhausted after the smallest activity the oxygen never fully reaches their mitochondria. It is like trying to water a field with hoses full of pebbles: the flow trickles instead of streaming. Nitric oxide signaling is another casualty. Endothelial nitric oxide synthase normally produces NO to dilate vessels, improve blood flow, and support mitochondrial function. Oxidative stress, arginine depletion, and enzyme uncoupling reduce NO production in long COVID. Without it, vessels remain constricted, blood flow is irregular, and energy metabolism suffers. VEGF, the growth factor that directs vascular repair and new vessel formation, also becomes dysregulated, either underactive in some tissues or overactive in others, producing fragile and leaky capillaries. Together, this creates a vascular network full of potholes and detours instead of smooth highways. Autonomic dysfunction sits on top of this vascular instability. The autonomic nervous system depends on precise baroreceptor feedback from blood vessels to regulate heart rate and blood pressure. When endothelium and fascia baroreceptors are injured, the signals become erratic. The vagus nerve often loses tone, while sympathetic activity ramps up. The result is postural orthostatic tachycardia syndrome, dizziness, palpitations, and poor heart rate variability. Many long haulers describe it as their body “forgetting how to regulate itself.” In truth, the sensors and wiring have been damaged by inflammation and microclots.
Endothelial dysfunction is absolutely one of the key elements. 🔥🔥🔥🔥
The 30-Day Brain Upgrade (Part 3): Synthesis and Beyond
By the time you’ve completed the first three weeks, you’ll have built clarity, learned to see patterns, and trained your brain to become resilient under stress. The final phase of the program is about synthesis pulling all the pieces together, integrating what you’ve learned, and turning it into a living operating system for your mind. This is where scattered insights become a framework you can use long after the 30 days are done. Week four introduces the lens of first principles thinking. This is the discipline of stripping assumptions down to their most basic truths and rebuilding from the ground up. Instead of accepting received wisdom or half-formed beliefs, you ask: “What do I know for certain?” and “If I rebuilt this idea from scratch, what would it look like?” This lens forces deep clarity and often uncovers surprising solutions. The reading for this week comes from The Master and His Emissary by Iain McGilchrist. The book explores the divided modes of the brain the detail-focused left hemisphere and the context-seeking right hemisphere and how balancing them changes the way we perceive reality. The point isn’t to get lost in theory, but to see how attention, perspective, and context shape your daily decisions. Memory practice in week four focuses on teaching back. The best way to prove you’ve learned something is to explain it to someone else or even to an imaginary student. Each day, take one idea from reading or journaling and explain it out loud in plain language. This cements knowledge and builds the skill of translation: turning complex ideas into simple, actionable language. The prompts for this week invite integration. Ask yourself: “What’s one idea I can integrate across fields?” and “How can I reframe this problem as an opportunity?” The goal is to combine what you’ve learned into something practical bridging concepts from psychology, philosophy, and personal experience into one system. Rest practices shift toward reflection. Long walks, sauna sessions, or quiet yoga give you space to process and connect dots. Unlike earlier weeks where rest included hormetic stressors, this week’s rest is about deep integration slowing down enough for the pieces to fit together.
Rewiring the brain is fascinating, just waking up and saying “today is going to be a great day” has been transformative for me, setting up the mind for great vs the unknown. This program is very detailed and easy to follow with interesting reading and assignments. Thank you!
The 30-Day Brain Upgrade (Part 1): The Blueprint for a Smarter Brain
Most people focus on training their bodies but rarely put the same discipline into training their brains. Yet the brain works like a muscle—it responds best when challenged, stressed, and given time to recover. The 30-Day Brain Upgrade is built on that principle. In less than an hour a day, you can rewire your mental routines, sharpen memory, and expand creativity. This first part of the series lays out the weekly structure, the five core pillars, and the first two weeks of practice. The weekly rhythm is simple. Days one through five are work days, focused on thinking routines, reading, and memory practice. Day six is an experiment day, where you apply creative prompts or break patterns. Day seven is integration, where you step back, rest, and reflect. This cycle repeats each week with added complexity so your brain adapts progressively. The five pillars are the scaffolding of the program. The first is high-IQ thinking routines—different mental lenses applied each week: asking five whys, steel-manning the opposite side of an argument, mapping systems, and breaking ideas down to first principles. The second pillar is daily journaling prompts like “What would my life look like if I doubled my learning speed?” or “Which belief of mine might be outdated in five years?” The third pillar is advanced reading, one book per week that challenges and expands your mind. The fourth is memory techniques, beginning with the method of loci and progressing to chunking, dual encoding, and teaching back. The final pillar is strategic rest short daily practices like box breathing or NSDR, a weekly digital fast, and consistent sleep. Week one is about foundations: clarity and focus. You ask “Why is it so?” on daily observations, read chapters from Daniel Kahneman’s Thinking, Fast and Slow, and build your first memory palace. Each day ends with a short rest practice. On day six you do a mental fast, avoiding input for two hours and journaling the ideas that surface. On day seven you unplug for several hours and write a one-page summary of three insights and one action to apply. By the end of the week, you’ve sharpened attention and cleared space for deeper learning.
Very Interesting
I Am Stumped! Calling All Brilliant Minds 🙏
My fiancé has been dealing with some peculiar issues that I’m trying to connect the dots on and would love input. She had lower leg swelling in the past that eventually resolved, and a remote history of Morton’s neuroma that hasn’t been symptomatic for years. Right now her main struggles are poor sleep, consistently low energy, chronic back tightness, and most notably significant thumb pain with joint locking. She describes it as if the thumb “needs to be pulled out.” Both sides were affected at first, but interestingly the untreated side resolved spontaneously while the PRP-treated side continues to be painful and lock regularly. Her job as a personal trainer and working retail means a lot of daily standing, hand and wrist loading, and repetitive strain. Emotionally, she’s carried stress since her father passed away three years ago she handled it well but still has difficult days. Nutritionally, she was vegetarian for about 40 years before introducing chicken 5–6 years ago, but otherwise eats minimal animal protein. My working thought is that this may not just be an isolated tendon or joint problem but a systemic terrain issue possibly a fibrosis-prone environment that explained the paradoxical PRP result, along with lymphatic or vascular fragility from standing all day, circadian and mitochondrial dysfunction contributing to poor energy and recovery, long-term nutrient debt from decades of vegetarianism (creatine, carnitine, B12, zinc, glycine, proline, lysine), and stress physiology from her HPA axis that stiffens fascia and keeps her in sympathetic tone. I’ve sketched out a phased protocol: first reset terrain with circadian support (melatonin or Epitalon), mitochondrial stack (SS-31, Kenetik Pro, plasmalogens), lymphatic strategies (compression, walking, electrolytes), and add Amlexanox as a fibrosis/inflammation reset. Then in phase 2, move to matrix remodeling with BPC-157, TB4, Pentosan Polysulfate, phosphatidylcholine, local tendon glides, red light, topical magnesium, and NeuFit or PEMF for fascia and back tightness, alongside nutrient repletion with collagen peptides, vitamin C, glycine/proline, zinc, copper, and manganese. Finally in phase 3, focus on integration and resilience with Epitalon cycles, MOTS-c, sauna and cold contrast, tendon-friendly strength training, strict sleep hygiene, and nutrient support like creatine, carnitine, and DHA/EPA. I’d re-evaluate with imaging if the thumb pain and locking persist or run labs if swelling recurs. My questions are: does Amlexanox make sense as a first step to rebalance the inflammatory/fibrotic terrain before PPS or repeat PRP? Is the PRP paradox more likely a redox/cellular terrain issue or immune imbalance? And am I over-attributing her back tightness and energy issues to systemic inflammation/lymphatics, or does that reasoning fit? Would love to hear how you all would think through this. @Elizabeth Yurth @Cynthia Keller @Carl Paige @Eric Fete @Eric Serrano anyone else! I’m here to learn and I want to be able to help her.
@Elise Kowalewski absolutely all the hormones need to be balanced including testosterone and DHEA .
@Brady Nielson someone once said to me “thoughts are things and words are things “ which opened a whole new door for me. Dr. Daniel Amen and Dr. Caroline Leaf have a wealth of information on the topic of emotions, thoughts , neuroplasticity and so much more.
