Ad text

I don't give a f*ck how this sounds coming from a doctor. There is a country where multiple sclerosis is more than twenty times rarer than it is here. "The prevalence of multiple sclerosis in Japan was 14.2 per 100,000, compared with 309.2 per 100,000 in the United States." I found that study at 2 in the morning, on the worst night of my life. And it's the reason I can still type this with both hands. My name is Dr. Sabrina Roger. I'm a board-certified neuromuscular specialist with twenty years in practice. I have run more than 12,000 nerve conduction studies, the test that measures the electrical signal running down a living nerve. I put the needles in, and I read the tracings. I have told hundreds of people exactly what their own nerves were doing. It is the one corner of medicine where you can watch a nerve fail in real time. I spent two decades watching it happen to other people. And then, nine years ago, it happened to me. I was diagnosed with MS. If you have MS, or someone you love does, I am asking you to read this all the way to the end. I know it is long, and I know you are scrolling. But I am about to tell you the thing I spent nine years and an entire career failing to find on my own. I would give anything to have heard it sooner. Six months ago, out of options and ready to walk away from my practice for good, I flew to Japan instead. I needed to understand why the people there almost never get the disease that was taking my body apart. I spent three days in a clinic in Tokyo with a doctor named Kenji Sato. What he showed me in those three days is the reason I did not quit. Let me walk you through it, exactly the way it happened to me. The flight to Tokyo is fourteen hours. I spent most of it not sleeping. That gave me fourteen hours to think about the fact that a fifty-six-year-old nerve specialist was crossing the Pacific to find the answer. I had a resignation letter still half written on the laptop in the seat pocket in front of me. I need to tell you what I was carrying onto that plane, because none of the rest of it makes sense without it. I went into nerve medicine because of my mother. She had MS. She was diagnosed in her forties, and for nine years the word her doctors used was the one everyone wants to hear. Stable. No new lesions. Well controlled. She would come home from those appointments having just been handed the best news there is. But for some reason, she just kept getting worse and worse. It came for her hands first. The buttons on her blouse became hard to do. Then it took her ability to hold a fork. My father eventually had to start feeding her her meals. Then it came for her legs. She stopped walking at 61. She spent the last four years of her life needing full-time help, in a facility, and she passed there at 67. Her final MRI was read clean. No new lesions. I built my entire career on a promise I made at her bedside. That I would understand the nerve well enough to keep my own patients out of the chair she died in. Then, nine years ago, I became my own patient. I was diagnosed with relapsing remitting MS at 47. I did not need anyone to interpret it for me. I could read my own nerve conduction studies. I could see, in my own tracings, the exact thing I had spent two decades pointing out to other people. The exact thing that had taken my mother. The signal slowing down, and the coating coming off. And I did everything right. Everything. I started a disease-modifying therapy the week I was diagnosed, and I escalated when the guidelines told me to. I have not had a relapse in six years. I took 5,000 IU of vitamin D every single day, did the physical therapy, and bought the cooling vest. I gave up gluten and then dairy and then did the nine-cup-of-vegetables version of the whole thing. I lost fifteen pounds and kept them off. I checked every box on my own protocol. I checked boxes most of my patients cannot afford to check. And every year, my brain MRI came back the same. No new lesions. Stable. I told myself the drug was working. I told myself I had done what my mother's doctors never managed to do. I am a nerve specialist. If anyone was going to stay ahead of this, it was going to be me. I was wrong, and I found out I was wrong in my own lab, holding a needle over my own patient. My hands had been getting slower for a year. I had blamed my age, and I had blamed the long days. Then one afternoon I could not place a fine-wire needle cleanly in a study I had done ten thousand times. I had to hand it to my technician, walk out of the room, and stand in the hallway to breathe. That night I did the thing I had refused to do for nine years. I stayed after everyone had gone home, and I ran a full nerve conduction study on myself. Nobody was watching the screen but me. The numbers were worse than I had let myself believe. Conduction velocities were down across the board. The signals in my own hands and feet were arriving late and frayed. It was real, measurable demyelination in fibers small enough that my brain MRI had never once shown a thing. My scan said stable. My own nerves, on my own machine, were screaming. I scheduled the rest of the workup for myself. And then I canceled it. I need to be honest about that, because it is the most honest thing in this whole letter. I canceled it because I already knew what it would show, and I did not want it in writing. I had watched my mother be called stable for nine years while the disease took her apart underneath the word. Now I was watching the same thing happen inside my own body, and I did not have the courage to make it official. I told myself I had time. I ran out of the luxury of pretending over the months that followed, one measurement at a time. My grip kept dropping, and I blamed my age. I was getting up twice a night, and I blamed coffee. My reports were taking me longer to write, and I blamed my clinic volume. My feet burned at night, and I blamed my shoes. Every one of those was the same disease, in a different nerve, progressing while my scan stayed perfectly stable. Not one of them was a relapse. And I was the one person on earth who could not tell myself a comforting story about it, because I could read the tracing. I want to be honest about where I got to, because it is the reason any of this matters. I had decided to stop fighting. I was going to wind down my practice, tell my partners I was retiring early, and let the disease take whatever it was going to take. I wasn't going to spend one more year chasing something that clearly did not exist. I had the resignation letter half written. I had tried everything a specialist knows how to try, and my own nerves were still going dark. I was tired in a way that had nothing to do with sleep. The night before I meant to finish that letter, I could not sleep. I did what doctors do at 2 in the morning. I read. I fell into the global maps of this disease. Where it is common. Where it is rare. That was the night I found the number I opened this with. Japan, at a fraction of our rate. And it was not genetics, because as Japan westernized, the disease climbed. As the food moved from the fishing village to the convenience store, their fish consumption alone fell by more than forty percent. MS moved into the space it left behind. The trail pointed at the old Japanese diet. But the papers could only tell me what had changed. They could not tell me why it mattered, or what a person was supposed to actually do about it. So I found the doctor whose research I kept circling back to. Dr. Kenji Sato, in Tokyo. I wrote to him that same night, and I told him the truth. I was an American nerve specialist who had run out of everything, including hope. He answered before I finished my coffee the next morning with one line: You should come. I will show you what the journals cannot. I did not finish the resignation letter. I booked the flight instead. Which is how I ended up on that plane, fourteen hours over the Pacific, landing at Haneda so exhausted I could barely read the signs. Dr. Sato met me himself. He was soft-spoken, careful, and older than his photograph. He had a steadiness about him that I had lost somewhere in the last year. The first morning, he took me to his clinic, and what I saw in his infusion room stopped me where I stood. Half of his MS patients were receiving a disease-modifying drug, the same infusions I would have hung for them at home. But right beside it, as a matter of ordinary routine, they were receiving three vitamins. B1, B6, and B12, in the active forms, at real doses. Some of it was by injection, going straight past the gut and into the bloodstream and the nerve. I asked him why. He looked at me the way you would look at someone who asked why you breathe. He said, "Dr. Roger, in Japan we treat two things. We stop the attack, and we feed the nerve so it can repair the attack." "In your country you do the first, and you call the work finished. You do half of it, and then you are surprised the patient keeps getting worse." There was no unkindness in it. He said it the way you tell a colleague something so obvious you cannot believe they were never taught it. Then he sat me down and explained the half of this disease my training had covered in a single afternoon twenty years ago and never returned to. I am going to give it to you exactly the way he gave it to me. "Your nerves are wrapped in a coating called myelin," he said. "Think of the insulation on an electrical wire." With the coating on, only the tiny gaps in the nerve have to do any work. The signal is fast, and it costs almost nothing. Strip the coating off, and the whole length of the nerve has to do the work instead, every single time it fires. That takes an enormous amount of energy. Not a little more. Far more. I was nodding, because I measure exactly this for a living. He said, "MS is two problems, not one. The first is the immune attack that strips the coating, and your medicine is very good at slowing it." "But the second problem is that a bare nerve cannot put its coating back unless it has two things inside the cell. The energy to do the repair, and the material to build it from." Your medicine does nothing about either. It stops the attack. Then it leaves the nerve bare, and starving. And the nerve keeps failing, for years, while the scan looks perfect. And there it was. Every failure of my own body, in one sentence, from a man I had known for a morning. He had a name for it. He said your journals call it progression independent of relapse activity. More than half of the disability people end up with does not come from a relapse at all. No new attack. No new lesion. And it gets worse anyway. That is the part your MRI was never able to see, and the part your medicine was never designed to touch. Sitting in his clinic, I thought about my own tracings. Six years without a relapse, and my conduction velocities falling the entire time. I had been staring at the proof of exactly what he was describing, on my own screen, for six years. I just never had the framework to understand what I was looking at. He told me the material and the energy were not exotic. They are three vitamins, he said: B1, B6, and B12. We call them the neurotropic vitamins, because they act only on nerve tissue. B1 makes the energy inside the nerve, B12 is the material the coating is rebuilt from, and B6 lets the nerve fire a clean signal. Energy, then material, then signal, in that order. Miss one and you get almost nothing. He slid a paper across his desk. A study from the year before. When those three were given together to damaged nerve cells, he said, they drove real remyelination. It was twenty-six times more effective than B12 given on its own. Then he told me why the vitamins have to be the right form and the right delivery. This is where I stopped being a skeptic. "A B vitamin you swallow barely arrives," he said. "A tablet absorbs about one percent, and almost none of it reaches the nerve." Your American doctors run a blood test for B12, the number comes back normal, everyone relaxes, and it means nothing. Because the level floating in the blood is not the level inside the nerve cell. Those are two completely different questions, and your system only ever asks one of them. I thought about the B12 test I had ordered on myself two years earlier. It had come back squarely normal, and I had been quietly reassured by it. It had told me nothing at all about the nerves that were dying in my own hands. And the forms matter as much as the delivery, he said. There is a cheap version of each of these and a real one. Cyanocobalamin instead of methylcobalamin. Pyridoxine instead of the active P-5-P. The cheap ones are synthetic, and the body can barely use them. Nearly everything on your American shelves is the cheap one. Worse, the cheap B6, at the doses your pharmacies sell it in, can actually damage the nerve you are trying to protect. I have seen your nerve formulas with a hundred milligrams, but the nerve needs one to three. I sat in that Tokyo clinic, twenty years a specialist, and took notes like a first-year resident. On my second day, I asked him the question I had crossed an ocean to ask. How did you find this? This is not in the guidelines I was trained on. How does a neurologist end up building his whole practice around three vitamins? He was quiet for a moment. Then he said, "Come. I will show you where it started." He drove me two hours out of the city the next morning, to the coastal town where he grew up, and he told me about his grandmother. Her name was Fumiko. She was diagnosed with MS in the 1960s, in her forties, when there was no treatment at all. No disease-modifying drug. Nothing. The doctors told the family she would be in a bed within ten years. She was not. She lived to 94. She walked to the market the week before she died. She lost the vision in one eye once, early on, and it came back. After that, the disease simply never took anything else from her that mattered. "And nobody in the family thought it was strange," Dr. Sato said, "because nobody knew it was supposed to be a tragedy." They just watched Grandmother Fumiko keep living, and they ate what she ate, because she cooked for all of them. She made her own miso, he said. She buried it and let it ferment for two years. She ate natto every morning, the fermented soybeans most foreigners cannot stand. Seaweed in everything. Small fish, whole, bones and all. The food of a poor coastal family, and it happened to be the richest source of the exact three vitamins a damaged nerve needs, in the exact forms the body can use. He said, "And here is the thing almost nobody knows. The soybean itself has no B12 in it. None." "It is the fermentation, the long dark months in the crock, that creates it. My grandmother was not taking a supplement." She was eating the repair, three times a day, for ninety years, and she had no idea she was doing it. I asked him when he understood what he had been watching his whole childhood. "In medical school," he said. "I learned the biochemistry of myelin repair, the energy and the material. I sat in the lecture and I thought, that is my grandmother's breakfast." That is natto. That is miso. That is the seaweed I hated as a boy. "Then I went and looked at the map," he said. "And I saw that as my country stopped eating the way my grandmother ate, the disease she beat without a single drug started to become common." "And I decided I was not going to spend my career doing half the job." I have to tell you what happened to me standing in that garden, because it is the reason I am writing this instead of sleeping off the jet lag. There were dark earthen crocks along the wall of his family's old house, the ones Fumiko had used, taller than my knee. And standing next to them, I did not think about biochemistry. I thought about my mother. I thought about her in that facility, ninety minutes from my house, being told once a year that her scan was stable while my father cut her food. I thought about how hard she fought and how little anyone ever gave her to fight with. And I thought about a woman in a Japanese fishing village who beat the same disease for fifty years with a bowl of fermented soybeans and never knew she was in a war at all. One of them lost everything. One of them walked to the market at 94. The difference was not the drug, because Fumiko never had one. The difference was that one of them spent her whole life feeding the nerve, and the other never got the chance. And I understood, standing there, that the thing I had been about to give up on was not the disease. It was the search. I had decided the answer did not exist because my own country had never once handed it to me. And it had existed the whole time, in a form so ordinary that a grandmother had been doing it by accident since before I was born. I flew home two days later a different person than the one who had left. But I am a fifty-six-year-old American with a practice and a mortgage. I was not going to bury miso in a crock for two years, and I was not going to fly to Tokyo every month for an injection. What I needed was those exact three vitamins, in the active forms Dr. Sato used, delivered in a way that got them past the gut and into the nerve without a needle. Dr. Sato told me the delivery mechanism already existed. It's called a liposome. It is a microscopic sphere built from the exact same material your own cell membranes are made of, with the vitamins sealed inside. Because the shell and the membrane match, the two fuse, and the vitamins are released directly inside the cell. It does what his injection does, but it does it under your tongue. I spent the entire fourteen-hour flight home reading the clinical data on it, and I was convinced. But when I landed and went looking for it, I hit a wall. I tore through the labels of every nerve supplement on American pharmacy shelves. It was exactly the garbage Dr. Sato had warned me about. Cheap cyanocobalamin. Synthetic B6 at toxic doses. And absolutely zero liposomal delivery. They were selling false hope in a capsule. I was actually looking into custom-compounding the active forms myself, which would have cost me hundreds of dollars a month, when a colleague finally pointed me toward a small clinical lab doing it right. The formula is called Nuvel Liposomal Neurotropic Vitamins. It has all three neurotropic vitamins in one bottle. 5,000 micrograms of active methylcobalamin. Benfotiamine for the energy. It uses B6 as the active P-5-P, held at a dose where it is safe, avoiding the high-dose synthetic form that quietly poisons the nerve. Every ingredient is in the form the body can actually use. And it is liposomal, so it reaches the tissue instead of sitting in your blood where a lab can see it and your nerves cannot. A few drops under the tongue, once a day. That is the entire protocol. I started it the morning after I got home, and I did the one thing my training actually made me good for. I measured myself. Week one. The fatigue that had been flattening me every afternoon eased just enough that I got through a full clinic day without lying down in my office. I noticed only because I looked up and it was evening. Week two. The burning in my feet that had been waking me past 2 most nights went quiet. I slept with the covers over my feet for the first time in a year. Week three. My grip started coming back. I did not measure it on purpose, I just opened a jar over the sink without thinking. I stood there holding the lid, trying to remember the last time that had been automatic. Week five. I placed a fine-wire needle cleanly in a patient study for the first time in eight months. My technician did not know why I had to turn around for a second afterward. Week eight. I ran a full nerve conduction study on myself again, after hours. The same way I had run the one that nearly ended me. The conduction velocities had come up. For six years that number had done exactly one thing. It fell. Now it was climbing, measurably, in fibers that had done nothing but slow down for six straight years. I ran the study three times because I could not believe my own machine. In twenty years I had never once watched a nerve get faster. Not once. Nerves are not supposed to be able to do that. Mine were doing it. And my brain MRI, when I had it repeated, said exactly what it has always said. No new lesions. Stable. Same two words. Completely different nerves underneath them. I brought the tracings to my partner, another neuromuscular specialist. I laid the study from that terrible night next to the one from week eight and I did not say a word. She read them twice. Then she looked up and said, "Sabrina. What did you do." I told her all of it. The number at 2 in the morning, the email, the flight I hid from everyone. Dr. Sato's infusion room and his grandmother's miso crocks. She listened for an hour without interrupting. Then she asked the only question that mattered, the one I would have asked her. Whether my DMT could account for it. It cannot. The DMT stops new lesions, but it has no remyelinating mechanism, and no trial of it has ever measured one. I had been on it for six years while my nerves went dark. The only thing that changed was the vitamins. She has been running it with fourteen of her own patients since. She called me last week. Nine have improved on their studies. Two who could barely hold a coffee cup a year ago brought her a photo of themselves holding a grandchild. I am still on my DMT. I always will be. This was never instead of my treatment. It is the other half. The half my own country never gave me, and never gave my mother, until I got on a plane and went to find it. I am also writing this because I know exactly what my profession has been doing, and I am the profession. I have read thousands of nerve studies in my career, and hundreds of MRI reports. Every time I saw the word stable I believed I was delivering good news. I watched the relief break across people's faces. And I sent them home. I sent them home to keep getting worse. I sent them home believing the scan meant they were safe. I sent them home without the one thing their nerves were starving for. And I do not know how many of the people I reassured are in a chair now, because their nerves were dying in fibers too small for the scan while I told them they were fine. The scan cannot see the myelin degrading. It never could. Stable means no new lesions. It does not mean the damage is being repaired, because nothing you have been given repairs it. Your DMT does not rebuild myelin. Keep taking it, it is doing its job. Steroids do not rebuild myelin. Physical therapy does not rebuild myelin, though you should keep doing it. Vitamin D does not rebuild myelin. I took it every day for nine years and my own nerves went dark anyway. Rebuilding myelin takes three specific things, and all three have to get inside the nerve. B12 for the material. B1 for the energy. B6 for the signal. They must be in the active forms, at clinical doses, in a delivery that puts them inside the cell instead of leaving them in your blood where a test can see them and your nerves cannot. Nuvel Liposomal Neurotropic Vitamins. All three, in one formula. 5,000 micrograms of active methylcobalamin. B6 as P-5-P, held where it is safe. Every ingredient in the form your body can actually use. Liposomal, so it reaches the nerve. One dose every morning, under the tongue. I am deeply cynical about the supplement industry. The only reason I am linking to Nuvel is because they do something I have never seen a pharmaceutical company do in my twenty-year career. They tie their money to your actual clinical results. They offer a 90-day guarantee. If your grip, your walking, or your fatigue hasn't measurably changed in three months, you do not pay for it. In twenty years, I have never once seen a drug company offer to refund you if their infusion did not work. Sit with that. Because they refuse to use synthetic B6, sourcing the active P-5-P is incredibly difficult. They produce this in small, clinical batches to protect the active forms. That means they frequently go on backorder. If you click the link and they actually have it in stock, do not wait. I flew to the other side of the world and sat in a grandmother's garden to learn what should have been on the first page of my own training. You do not have to. Dr. Sabrina Roger, MD Board-certified neuromuscular specialist P.S. Six months ago I had a resignation letter half written and a plan to let this disease take whatever it was going to take. The only reason I did not send it is a number I found at 2 in the morning, a doctor in Tokyo who answered a stranger's email, and a woman named Fumiko I never met, who beat this disease for fifty years with a bowl of fermented soybeans. If you are where I was, please do not make the decision I almost made. The answer was never that it did not exist. The answer was that nobody in my own country was ever going to hand it to me. So I am handing it to you. P.P.S. I do not work for Nuvel and I do not receive a penny from this. I paid for my own flight to Tokyo, and I pay for my own bottles every month. I am writing this at midnight because a patient came into my lab last week with improved studies, and I knew I couldn't stay quiet anymore. Please send this to anyone you love who has MS. Even if they are doing well. Especially if they have just been told they are stable.
