Prodrome Science™ — Webinar Series
Why stroke recovery isn’t mechanical — and what actually protects and restores the brain.
Dr. Goodenowe presents the complete biochemistry of stroke — the uncomfortable truth about conventional acute care, the specific nutrients shown to protect the brain, and the evidence that the brain can be structurally restored years after a stroke.

Dr. Goodenowe opens this webinar with a warning that it will be, in his words, “a bit disturbing” — especially for anyone who has suffered a stroke. “It made me angry when I was putting this together,” he says. “But we’re going to get through this together, and we’re going to look at the underlying biochemistry of stroke and what you can do to better your life.” What follows is a reframing of stroke recovery that departs sharply from the conventional mechanical model — and, like his other webinars, ends on a genuinely hopeful note about what the brain can recover.
“There’s actually no such thing as mechanical failure in the human body. There is only biochemical failure. When your arteries fail, it’s not a mechanical failure — it’s a biochemical failure. And this also means there’s no such thing as mechanical healing. There’s only biochemical healing.”
Dr. Goodenowe argues that conventional stroke care “appears to be scientific—they dress up their research in scientific clothing” but that in reality “they really have no idea why people recover or die from a stroke.” The approach, he says, is mechanical: “They take a mechanical approach to the cardiovascular system much like a plumber takes a mechanical approach to your house. They try to physically connect the pieces, clean the piping using physical devices and chemical cleaners. They then send you home proud of their work, and the rest is mostly left up to random luck and chance.”
The problem with that model, according to Dr. Goodenowe, is that the body isn’t plumbing. “The human body is not mechanical. It’s biochemical. It’s not made of dead material like copper and wood. It’s made up of a network of 30 trillion cells. Your bones are alive. Your muscles are alive. Your brain is alive. Your vascular system is alive, and it heals itself with living matter.” A stroke, in his framing, is “a cardiovascular disease outcome — a heart attack of the brain” — and its recovery follows biochemical rules, not mechanical ones.
Dr. Goodenowe is careful here: restoring blood flow in the emergency phase is a genuine priority. “Restoring blood flow is an emergency priority and you should take that seriously. Anything you can do to improve blood flow is a positive outcome.” His concern is with what the acute intervention is presented to accomplish versus what the real-world data show. “Emergency blood flow restoration is just the beginning of the stroke recovery journey, not the end.”
He points to the gap between clinical-trial conditions and reality: “In the practical real world, where all of you will be living — as opposed to the perfect clinical conditions where basically nobody lives — theory and reality don’t match.” He reviews real-world outcome data on thrombectomy showing high rates of recurrent stroke, and notes that for thrombolysis outside the narrow treatment window, the trial data can actually favour the control group. His conclusion is not that people should refuse emergency care, but that they should understand its limits: “The point of the story here is that your brain is not copper piping. You cannot expect to reconnect and clean them, and things will just go back to normal.”
Dr. Goodenowe frames health as a “singularity” — something we all share and that is unambiguous — while disease is individual. “Your health and my health is the same. Your stroke and my stroke will be different.” Before a stroke, he explains, there is a risk phase — what he calls the prodrome. Conventional care treats the acute event and then “puts you back in the same risk scenario, which is why the recurrence of stroke in a stroke person is much, much higher than stroke in the average population. Because the reason why you got the stroke in the first place was never corrected.”
His analogy is blunt: “This is putting a patch on a bald tire and waiting for the next flat. Eventually the tire is unfixable and you die.” The restorative alternative, in his framing, is to “understand why you had a stroke and fix the prodrome” — restoring the risk phase back to a healthy phase, then maintaining that health over time.
The core of the webinar is a set of published studies on simple, inexpensive biochemical factors that Dr. Goodenowe argues the conventional system largely ignores. “Stroke recovery is all about protecting this penumbra and the rest of your brain,” he says — the penumbra being the “shadow” region around the initial injury that can either be saved or lost. He walks through six of them:
Coenzyme Q10. Dr. Goodenowe notes that serum CoQ10 is depleted in stroke and that the depletion correlates with severity. In a severe animal stroke model, he reports, “a single IV administration of coenzyme Q10 restored the CoQ10 levels” and dramatically reduced mortality — in one arm raising survival to 100% — while preventing the lesion from growing between day one and day four. “Dramatic preservation of the penumbra with a simple mitochondrial support supplement.”
Riboflavin (B2). “25% of the population is deficient in riboflavin,” he says, and “just a small amount of B2 reduces your risk of having a stroke by 50%.” In animal models, pretreatment with B2 reduced infarct areas by nearly half.
Niacin (B3). “50 milligrams of niacin reduces your stroke risk by 50%.” He is specific that he means “the old-fashioned” flushing form of niacin (nicotinic acid), which works through lipid pathways — distinct from niacinamide — and stresses it “should only be taken once” a day and always with professional advice.
Thiamine (B1). Fatigue is a major, under-addressed problem after stroke. Dr. Goodenowe cites cases in which high-dose thiamine (around 100 mg) brought severe post-stroke fatigue scores down to normal levels.
N-acetylcysteine (NAC). A precursor to glutathione, NAC addresses the oxidative-stress burst that follows reperfusion. In a randomized, double-blind, placebo-controlled human trial, Dr. Goodenowe reports, NAC-treated patients had significantly better stroke scores and functional outcomes at 90 days — roughly 58% achieving favourable recovery versus 29% on placebo, “an odds ratio of two.”
Acetyl-L-carnitine. Carnitine “improves mitochondrial function and buffers mitochondrial stress.” In a clinical trial in acute ischemic stroke, complete recovery was significantly higher in the carnitine group — about 72% versus 40%.
“Biochemical support outperforms current FDA-approved drug therapy, period. The point is the brain is biochemical, and it responds to biochemical support.”
Dr. Goodenowe is careful to frame this responsibly: he is showing published research, not prescribing. “Doctors are given no advanced nutritional or biochemical training. There are no prescribing guidelines… So don’t blame your doctor, but don’t be a victim either.” His point is that this knowledge exists in the literature but hasn’t reached routine practice — and that patients can bring it to their own healthcare providers.
Working backward from the stroke itself, Dr. Goodenowe traces the chain: “Atherosclerosis is the underlying cause of all strokes… Endothelial dysfunction is the underlying cause of that atherosclerosis.” The endothelium is the single-cell lining that seals the arteries; when it becomes leaky, oxidized LDL and inflammatory plaque build up, eventually either blocking a vessel (ischemic stroke) or bursting it (hemorrhagic stroke).
Notably, he pushes back hard on the cholesterol narrative. Asked directly whether high cholesterol causes stroke, his answer is “No.” The culprit, he argues, is oxidized phospholipids on the LDL particle — not cholesterol itself, which he calls “basically indestructible.” He points instead to markers like C-reactive protein, malondialdehyde, and low HDL as far more meaningful, and identifies hydrogen peroxide and oxidative stress — along with diabetes and high blood pressure — as the real drivers of endothelial dysfunction.
One of the webinar’s central points is that a stroke doesn’t end when the acute event is over. “Your stroke doesn’t go away an hour or two days afterwards. There is a progressive inflammation that continues to damage your brain.” The driver is microglial activation — the brain’s immune cells — which, when they can’t heal the injury, begin “chewing up your white matter,” the myelin that insulates the brain’s wiring. This is why, he explains, white-matter degeneration and cognitive impairment can persist for years after a stroke.
This connects to his signature research on plasmalogens — the phospholipids that make up the brain’s white matter and that become depleted in stroke and inflammation. In demyelination models, he reports, supplying plasmalogen precursors produced “complete preservation of the myelination” — in fact more myelin in treated animals than in untreated controls. “If you provide the brain with the right biochemical support, it has tremendous restorative capacity.” In human studies, plasmalogen precursors improved cognition and mobility — the two functions most affected by stroke — and improved oxidative-stress markers.
To show that restoration is real and measurable, Dr. Goodenowe presents two cases using advanced MRI that maps 600 regions of the brain, 300,000–400,000 fiber tracks, cortical thickness, and blood flow over time.
Beginning an advanced MRI project in 2022 — expecting to serve as a healthy control — Dr. Goodenowe discovered his own brain carried old damage from a childhood concussion at age eight. “It’s important for all of us, no matter how good we think we are, to find out exactly what’s going on.”
He began a targeted brain-nutrition program — plasmalogen precursors, mitochondrial support, B vitamins, carnitine, N-acetylcysteine. Over four years, his brain showed no loss of volume (against an expected age-related decline), and his measured “brain age” fell from 50 to 41. “My brain is now 15 years younger than my chronological age, and this can be mapped and measured.”
Lisa has had multiple sclerosis since 1992 and had been blind for over 30 years. On a simple protocol — N-acetylcysteine, carnitine, curcuminoids, B vitamins, and plasmalogens — she began to experience restored vision about eight months in.
On advanced MRI, the areas of her brain associated with vision, which had been severely thinned, improved dramatically: of 18 regions thinned by more than two standard deviations, none remained afterward. Her occipital-cortex connectivity — the wiring from eye to brain — visibly rebuilt. “This is actually 30 years of blindness that the brain can actually restore itself after that long. It’s pretty amazing.”
The relevance to stroke, in Dr. Goodenowe’s framing: the same mechanisms of restoration — rebuilding cortical thickness, fiber connectivity, and blood flow — apply to the post-stroke brain. “So let’s talk about things that we know normally happen to the brain, and they’re going to be accelerated in a brain that had a stroke.” If the brain can restore after decades of blindness, the implication is that meaningful recovery remains possible long after a stroke.
“Your brain is like a castle. Once the walls have been breached, the battles must be fought and won on the inside. You need to get the biochemistry into the brain so it can fix its cells, fix its membranes, and restore itself.”
Dr. Goodenowe emphasizes that regular nutrition alone isn’t enough for a brain under this kind of stress, and that having the right supplies on hand — as the riboflavin and niacin studies suggest — matters even before any crisis, “in anticipation that even with the best safety protocols, accidents can happen.” His closing reassurance in the Q&A: “I know this all seems very overwhelming, but once you start taking it piece by piece… just get the big ones right. Even if you start with some simple stuff first, it’s better than nothing.” Asked for his top three post-stroke priorities, his answer was carnitine, N-acetylcysteine, and CoQ10 — alongside a good B-vitamin mix and plasmalogen precursors to rebuild the brain’s physical structure.
