DHA IS NOT JUST A FAT PART 6
By now, the core idea should be clear. DHA is not nutrition. Plasmalogens are not optional add-ons. Mitochondria are not broken engines waiting for more fuel. And inflammation is not the enemy. Across fatigue, poor recovery, cognitive decline, chronic inflammation, burnout, and early aging, the common thread is a loss of signal integrity at the membrane level. This final section exists for one reason: to turn that understanding into a way of thinking that prevents overcorrection, overstimulation, and endless symptom chasing. This is not a protocol. It’s an operating system. The first principle of a membrane-first approach is order. Biology always restores structure before increasing output. When we reverse that order, systems become fragile. When we respect it, systems organize themselves naturally. So the most important question is not, “What should I add?” It’s, “What is the membrane currently capable of handling?” That single question eliminates most mistakes. The first step in this hierarchy is de-noising. Before trying to improve energy or performance, sources of chronic membrane instability need to be reduced. Excessive omega-6 intake, oxidized fats, environmental stressors, poor sleep, and unmanaged psychological stress all increase background electron noise. Adding conduction or stimulation into an already noisy system only amplifies chaos. This is why people sometimes feel worse when adding DHA, mitochondrial supplements, or aggressive training. The system was already loud, and better wiring simply exposes the problem. De-noising isn’t exciting, but it’s foundational. The second step is buffering. Once noise is reduced, the system needs protection before speed. This is where plasmalogens matter. Buffering increases membrane capacitance and allows electrons to move without damaging surrounding structures. This phase often feels calming rather than stimulating, and that’s not a failure. Calm means signal coherence is improving. Better sleep, feeling more grounded, and reduced reactivity without an immediate surge in energy are signs this stage is working. It’s important not to rush past it.

I learned so much from these articles- thanks @Anthony Castore
DHA IS NOT JUST A FAT PART 3
DHA, PLASMALOGENS, AND MITOCHONDRIAL MEMBRANE POTENTIAL: POWER WITHOUT INSTABILITY At this point in the series, one thing should be clear: membranes are not passive. They are active regulators of signal timing, electron flow, and system stability. Nowhere is that more consequential than in the mitochondria. Most conversations about mitochondria focus on output. ATP. Energy. Fuel utilization. Fat versus glucose. Those discussions matter, but they start too late in the causal chain. Mitochondria do not fail because they lack fuel. They fail because electron flow becomes unstable. To understand why DHA and plasmalogens matter here, we need to talk about mitochondrial membrane potential, often abbreviated as ΔΨm. ΔΨm is usually described as voltage. A battery. A charge gradient across the inner mitochondrial membrane. That description is technically accurate, but conceptually incomplete. ΔΨm is not just how much charge exists. It is how controlled that charge is. A stable membrane potential means electrons move smoothly through the electron transport chain, protons are pumped predictably, and ATP synthase can operate efficiently. An unstable membrane potential means electrons back up, leak, and react with oxygen in places they shouldn’t. This is where most mitochondrial dysfunction actually begins. The inner mitochondrial membrane is not just a lipid barrier. It is a highly specialized electrical interface. It contains densely packed protein complexes, curved membrane structures, and unique lipid compositions. Its job is not to hold charge. Its job is to manage electron flow under load. DHA and plasmalogens directly influence how well it does that job. DHA alters the dielectric properties of the membrane. In practical terms, it changes how electric fields behave within the membrane. It reduces resistance to lateral electron movement and improves the probability that electrons move forward through the chain instead of backing up. This matters at Complex I and Complex III in particular, where electron congestion commonly occurs.

Outstanding article.
Plantar fasciitis
What are different protocols for plantar fasciitis?? Thanks

I see this a lot in my clinic. Follow the nerve pathways from the spine to the foot. The sural nerve will remain 'angry' ifs it aggravated else where. Bursitis- that's a load issue and the load causes friction on the bursitis. Check out training volume, bio mechanics and regular foot wear upgrade Between those two interventions- you may find better questions to ask. That's from a structural viewpoint 😊
Your Mitochondria Aren’t “Low Energy” — They’re Structurally Broken (And Pushing Them Harder Is Making It Worse)
Most conversations about mitochondria start in the wrong place. They start with energy production, ATP output, or how to “boost” mitochondria. That framing misses the real problem. Mitochondria don’t usually fail because they can’t make energy. They fail because the physical structure that allows energy to be made cleanly and efficiently becomes unstable. Once structure is compromised, every attempt to push energy production creates more noise, more oxidative stress, and more dysfunction. This is why people can have “normal” labs yet feel exhausted, wired, inflamed, or unable to recover. The issue isn’t fuel. It’s architecture. To understand this, we need to zoom in to the level of mitochondrial structure. Inside every mitochondrion is an inner membrane that folds inward into structures called cristae. These folds are not random. They are precisely shaped, tightly regulated, and essential for efficient energy production. Cristae dramatically increase surface area, but more importantly, they organize the electron transport chain into coherent, functional units. The electron transport chain is not just a series of enzymes floating in space. It is a spatially organized system embedded in the inner membrane. Distance between complexes, membrane curvature, lipid composition, and membrane tension all matter. A helpful analogy is an accordion. When the folds are evenly spaced, elastic, and well aligned, air flows smoothly and predictably. When the folds become stiff, warped, or collapsed, airflow becomes turbulent and inefficient. The same thing happens with electrons inside mitochondria. Electrons enter the electron transport chain and move through complexes I, II, III, and IV. As they move, they pump protons across the inner membrane, creating a proton gradient called membrane potential. ATP synthase then uses that gradient to produce ATP. When cristae structure is intact, electrons flow smoothly, protons are distributed evenly, ATP is produced efficiently, and reactive oxygen species remain low. When cristae structure is compromised, electrons leak, protons accumulate unevenly, membrane potential becomes excessive or unstable, and reactive oxygen species rise.

The Brain Doesn’t Break From Damage—It Breaks From Energy Debt (And Almost No One Thinks This Way)
Let’s begin by looking at aging and longevity through the lens of neuron survival. Most conversations about aging revolve around damage. Oxidative damage. DNA damage. Protein damage. The story we are usually told is that aging is the slow accumulation of wear and tear until the system finally breaks. That framing sounds intuitive, but it is incomplete. Cells do not usually fail because damage suddenly appears. They fail because their ability to repair damage, buffer stress, and maintain energy quietly erodes over time. Aging, at its core, is better understood as a progressive loss of energy resilience. Neurons are one of the earliest and clearest indicators of this process. They are among the most energy-demanding cells in the body, and unlike many other tissues, they cannot easily be replaced. They must maintain electrical gradients every second, transmit signals across long distances, repair DNA continuously, and coordinate complex networks that never truly shut off. This means neurons live very close to their energetic limits even under normal conditions. As NAD+ availability declines with age, neurons become less capable of surviving inflammatory stress, metabolic stress, and excitotoxic stress. Long before neurons actually die, this loss of resilience shows up as slower processing speed, poorer stress tolerance, impaired memory consolidation, reduced emotional regulation, and diminished adaptability. People feel “off” years or decades before anything that would qualify as neurodegeneration appears on a scan. From a longevity perspective, this reframes the goal entirely. Longevity is not primarily about adding years at the very end of life. It is about preserving cognitive, emotional, and functional capacity across the middle decades where most people actually live. Strategies that stabilize energy metabolism and reduce unnecessary NAD+ depletion are therefore plausibly longevity-aligned even if they do not regenerate tissue or reverse existing damage. The key shift is this: longevity is less about creating new cells and more about preventing avoidable cell loss.
