I'm going to lose my mind if one more person posts "I've been on gabapentin for two years, I've tried B12, I'm doing everything my doctor says, and the burning in my feet is STILL getting worse, what am I doing wrong?" and gets flooded with comments saying "ask about Lyrica" and "have you tried soaking them in Epsom salt?" YOU'RE NOT DOING ANYTHING WRONG. THE GABAPENTIN ISN'T THE PROBLEM. Your gabapentin turns down the pain signal so you can get through the day. It does not feed the nerve and it does not repair it. So while the pill quiets the alarm, the nerve keeps dying underneath it, and the numbness keeps spreading, even on a full dose. And swallowing more B12 doesn't fix that either, for reasons I didn't understand until I actually looked into it. My name is Sandra Keller. I've been a podiatric nurse for 31 years. In that time I've cared for thousands of patients with peripheral neuropathy. And I need to tell you something about the burning in your feet that's going to change everything you think you know. Because for more than a decade, I watched the same pattern repeat itself over and over. Someone gets diagnosed. Doctor writes gabapentin. Tells them to check their feet, watch for wounds, come back in three months. Then they come into the clinic. "Nurse Sandra, I don't understand. I take my gabapentin every single day. I do the foot soaks. But the burning keeps getting worse. Should I ask about a different pill?" I'd tell them what the doctors told me to tell them. "Let's see if they can add Lyrica. We could ask about Cymbalta next time." They'd add the new medication. Three months later: feet still burning. "What about increasing the dose?" Still burning. "Maybe try a nerve supplement. There are some with good reviews on Amazon." Still burning. This conversation happened so many times I stopped counting. And every time, the answer was the same. Adjust the dose. Add another pill. Keep checking your feet. Because that's what we're taught. Spreading numbness equals adjust the prescription. Add another drug. Keep watching the damage. Except the damage kept advancing. The numbness kept climbing on full medication. In 2021, I decided to start paying closer attention. I started keeping notes on every patient whose feet were getting worse despite taking gabapentin faithfully and doing everything the standard protocol required. Over the next year, I found myself looking at the same picture across dozens of patients. All of them medicated. All of them following instructions to the letter. All of them still getting worse. And I noticed something I'd been writing in charts for years without ever connecting it to anything. Almost every one of these patients had a managed A1C. Their number was in a range the doctor called controlled. I'd note it, move on. Nobody thinks twice about a managed number. But nobody had ever asked what that managed number was allowing to continue behind it. Whether the glucose still circulating at a managed level was still passing through every tiny capillary feeding the nerve fibers in their feet. Whether managed and safe were the same thing. Whether the tingling was evidence that something was already failing, or just a warning that something might. And here's what made me feel sick when I finally looked into it. Gabapentin works on the signal. That's real. It turns the volume down on the pain so you can sleep. Lyrica does the same. Neither one puts a single thing back into the nerve. Neither one touches the reason the nerve is dying in the first place. Your feet are the farthest point in your body from your heart. Last in line for blood. Last in line for everything. The nerve fibers running from your spine all the way to your toes are wrapped in a protective coating called the myelin sheath. That sheath is what allows signals to travel fast enough to tell your foot where it is in space, tell you when something is too hot, tell you when your shoe is rubbing wrong before it opens a wound you cannot feel. When blood sugar cannot clear the bloodstream, two things happen to that sheath and those fibers simultaneously. The tiny capillaries feeding the nerve fibers get inflamed and close off. The fibers starve of oxygen and nutrients. The outer fibers die first, then the middle layers. Tingling is a degrading signal. Numbness is further fiber loss. Burning is damaged nerves misfiring. At the same time, glucose physically attaches to the proteins in the myelin sheath itself. It warps the structure the same way heat warps plastic. The insulation breaks down. Signals cross-fire and misfire. So the nerve was being destroyed from two directions at once. And the medication was only addressing one piece, the pain signal, while the actual cause ran on unchecked underneath it. Every single day. And the numbness just kept climbing. Let me tell you about a patient who made me realize how serious this actually is. Her name was Carol. Sixty-three years old. Type 2 for seven years. Diagnosed with peripheral neuropathy two years before I met her. Carol's daughter called the clinic. "Nurse Sandra, she takes her gabapentin every single day. She buys the nerve supplements they recommend in her Facebook group. And every month the burning is worse and the numb patch on her foot is bigger. Her doctor just says let's try Lyrica. But what she's doing isn't working." "What is she on now?" "Gabapentin, 600 a day for the feet. They've been talking about going higher. She started taking a B12 supplement because someone in her support group said it helped. Her A1C is 7.2. Her doctor says it's managed." "How is she feeling?" "Exhausted. The pain is worst at night so she barely sleeps. She hangs her feet off the side of the bed to cool them down. She checks her feet every morning because she's terrified of missing a wound. And she's scared. Her uncle had neuropathy and ended up losing his foot. Carol can feel herself heading down the same road." I asked her to bring Carol in. When I saw Carol, she looked tired. A little unsteady on her feet. Careful with every step in a way that people who have lost sensation learn to be careful. I ran the monofilament exam myself. Ten points across both feet, the way it should be done. She felt three. Three points out of ten. The rest of the sole of her foot was dark on the map. Carol's burning was sitting at a 7 or 8 every single night, and the nerve was going quiet a little more every month underneath the medication that was supposed to be helping her. Her neuropathy wasn't progressing because her medication wasn't strong enough. It was progressing because the upstream cause, the glucose still circulating through the capillaries feeding her nerve fibers, was still running. The drug had quieted the alarm. The fire had not stopped. I called her daughter. "Carol's gabapentin is doing what it can on the pain signal. But the nerve fibers are still dying underneath it, and the numbness is spreading every month. That's why the burning keeps getting worse." "So the medication isn't enough?" I hesitated. But I had been reading. Not about a different drug. About the actual mechanism producing the destruction. About why a managed A1C is not the same as a safe A1C when it comes to the tiny capillaries feeding nerve fibers. About a compound that had been sitting in peer-reviewed journals for years that went directly to the cellular machinery responsible for clearing glucose from the blood, bypassing the broken signal entirely and waking up the process that was supposed to be clearing the flood all along. I wasn't ready to say any of that out loud yet. Not until I'd seen something change in her numbers. "Let's keep a close watch on her feet," I told her. "Track the burning. Don't wait three months, call me sooner if anything changes." Her daughter didn't want to just watch. She went home and ordered the highest-rated cinnamon capsules she could find on Amazon. The label said Ceylon. The reviews were good. Carol started taking them every morning. Week one: night burning still averaging 7 to 8. Still hanging her feet off the bed. Fasting glucose unchanged. Week two: maybe slightly calmer. Still a 6 to 7 at night. Monofilament unchanged. Week three: still three points out of ten. The burning had not moved. Week four: her daughter called me, frustrated. "Nurse Sandra, the cinnamon isn't working. She's been taking it every single day for a month. Nothing has changed." I wasn't surprised. That was the whole problem. "Bring her in. Let me check her feet again." The map was unchanged. Three points out of ten. The capsules weren't working, exactly like the research said they wouldn't. Not because the mechanism was wrong. Because what Carol swallowed was almost certainly not what the label said it was, was nowhere near the dose the research used, and had no way of crossing the cell wall even if both of those things had been right. "What exactly is she taking?" Her daughter held up the bottle on the video call. "That's the issue. Not the compound. The product." So I looked at what was actually built the way the research said it needed to be built. True Ceylon cinnamon. Concentrated extract at a therapeutic dose. Suspended in MCT oil so the fat-soluble active compounds had a carrier to cross the cell wall instead of passing straight through the gut unused. Only one product was built that way. Metabolae. I'd ordered it skeptically. A small company. A bag, not a bottle. A softgel, not a capsule. Claims I'd heard variations of before and dismissed. But it was the only one delivering the right species, the right dose, and the right delivery in a single softgel. Cinnamomum verum, sourced from Sri Lanka, DNA-verified at the species level with an actual Certificate of Analysis, not a label claim. Dosed at 7,200mg equivalent per softgel using a 12:1 concentrated extract, the dosing range that corresponds directly to the published clinical trials. Suspended in MCT oil from coconuts, not as a filler, as the fat bridge that carries the active compounds through the cell wall and into the cells where the GLUT4 transporters have been waiting years to be woken up. Third-party tested. GMP-certified. Every batch verified for purity, potency, and coumarin levels. I called her daughter immediately. "Stop the capsules. I'm sending you something different. This one actually delivers what the research is showing." I brought a bag of Metabolae over the next day. Carol took one softgel every morning at breakfast alongside her gabapentin. Week one: she mentioned something I didn't expect. The burning had been sitting at a 7 or 8 for months. She told her daughter it felt like a 5 two nights in a row. Not gone. But the lowest it had been in over a year. She slept five hours straight without hanging her feet off the bed for the first time in months. Her daughter texted me at 7 in the morning. "She slept through." Week two: Carol walked to the end of the street and back, something she'd been avoiding because she couldn't feel the pavement under her feet. That evening she wrote a 4 in her pain diary. She told her daughter she checked the number twice. Her fasting glucose had dropped from 141 to 108. Week three: Carol called the office herself. "I stepped onto the cold floor in my bathroom this morning and I felt it. The cold. Under my feet. I haven't felt anything under my feet in two years." She was crying. Her fasting glucose was 99. Week four: I ran the monofilament exam again. She felt six of the ten points. She'd felt three before. Her night burning was averaging a 3. The burning that had been waking her up at two in the morning every night had gone quiet. She was sleeping through. In four weeks on Metabolae, Carol's feet had moved further than they had in two years on gabapentin and two rounds of Amazon cinnamon capsules combined. In four weeks on the Amazon capsules, nothing had changed. Same gabapentin. Same routine. Different product. Her daughter called me crying. "Nurse Sandra, she slept through the night. She walked to the end of the street. She felt the cold floor in her bathroom. Her doctor ran the monofilament himself at her last appointment and asked what changed. Nothing changed except the Metabolae." "I know. The capsules never opened the drain. This one actually does." "Why didn't anyone tell us this?" I didn't have a good answer for that. After Carol, I made a decision. I was only going to recommend Metabolae. Not because I was getting paid. Not because I had some arrangement with them. Because it was the only one I'd found that was built the way the research said it needed to be built. Right species. Right dose. Right delivery. All three, in a single softgel. I started telling every patient who came in with spreading numbness despite taking their gabapentin faithfully: "Your medication is doing what it can on the pain signal. But the upstream cause is still running. And the cinnamon capsules on Amazon are not reaching the cells that need them. Don't buy another bottle of capsules. Use Metabolae. It's the only one I've found that gets the active compounds where they need to go." Over the past five months, I've recommended it to dozens of patients. All of them on gabapentin or Lyrica. All of them with spreading numbness despite doing everything right. All of them frustrated and scared. And almost all of them are starting to see the burning ease, their sleep come back, and their feet slowly go from numb to feeling something again. Not because they found the right pill. Because the upstream cause finally started being addressed. The glucose that had been circulating through the tiny capillaries feeding their nerve fibers started clearing. The drain opened. And the destruction that had been running silently underneath the managed number started slowing. But here's what haunts me. I started thinking about all the patients I'd cared for over 31 years before I knew any of this. The ones I just smiled at and told to stay on their gabapentin and keep checking their feet. I think about Robert. He was 66 when I first started seeing him. Just a little tingling in his toes. By his last visit he was on gabapentin and Lyrica both, foggy most days, shuffling when he walked because he couldn't feel where his feet landed. He'd stopped going to his grandson's baseball games because the bleachers were too far from the parking lot and he was afraid of going down. Then one evening he stepped off his back porch in the dark, missed the last step he couldn't feel, and went down hard. Hip fracture. He never went home. He spent his last year in a rehab facility watching the games on a small television they'd set up in his room. I think about Dorothy. Seventy years old. Came in for years with numbness she kept calling annoying. One afternoon she was in the kitchen and didn't notice she'd stepped on a piece of broken glass. By the time she looked down, there was blood on the tile. The wound didn't heal the way it should have. The infection moved fast. They took three toes. Six months later the conversation was about the foot. I think about Frank. Came in every quarter, quiet man, always said he was managing fine. The numbness in his feet had climbed past his ankles. One morning he came down his front steps, couldn't feel the edge of the last one, and went straight forward into the driveway. He hit his head on the concrete. He never woke up. The neuropathy didn't take him the way a diagnosis takes someone. It took his footing an inch at a time across four years of appointments where I told him his medication was doing what it could. That's three patients. I have more than I can count. People I told "you're doing everything right, just keep taking your gabapentin and checking your feet" while the actual upstream cause kept destroying their nerve fibers a little more every single day. I made a decision after Carol. Every patient with spreading numbness gets the monofilament pressed to every point on their foot at every visit. And every patient whose map is getting darker gets this conversation. Because "the burning is a little better" doesn't mean your feet are safe. If your numbness is spreading on medication, something upstream is still running. And the pills don't address it. They just mute the pain while the cause continues unchecked. I'm writing this because I see so many of you posting the same things Carol's daughter posted. "She's been on gabapentin for two years and the burning keeps getting worse." "The supplements aren't touching it. What are we missing?" "Trying to avoid a third nerve drug. She takes every pill on time. What else can we do?" You're not dealing with a medication failure. You're dealing with a cause that the medication was never designed to address. And I've watched what happens when this goes unaddressed for years. Robert. Dorothy. Frank. More than I want to count. If your numbness has spread in the past year, even on medication, ask your doctor to run the monofilament exam again and actually map what you can still feel. If they say "let's just increase the dose," find a doctor who will look closer. Because I've seen what happens when you only treat one piece. Months of spreading numbness turn into a second nerve drug. Then a third. Then a fall. Then wounds that will not close. Then a toe. Then a foot. Then the conversation about the level they will need to go to. Or you address the actual cause. Keep your medication if your doctor wants you on it. And give the upstream cause the answer that the gabapentin was never built to provide. The glucose that has been circulating through the tiny capillaries feeding your nerve fibers needs somewhere to go. The GLUT4 doors that stopped opening need something that bypasses the broken signal and wakes them back up. When they open, the glucose clears. The capillaries stop being choked off. The glycation of the myelin sheath slows. The fibers that are still alive stop being destroyed at the rate they were. The burning eases. The feeling starts to come back. You don't need another prescription for that. You need the right compound, the right species, the right dose, and the right delivery system, working alongside your current treatment, not against it. But, and this is important, don't just grab any cinnamon product without understanding why the last ones did nothing. Most of what's on the shelf fails on three specific points before it ever has a chance to work. First, species. The cinnamon in most products, including most of the ones labeled Ceylon, is Cassia. A completely different plant. Almost none of the active compounds that trigger GLUT4 activation. And at daily supplement doses, enough coumarin to silently stress a liver that is already under metabolic pressure. Carol's Amazon capsules said Ceylon. They were almost certainly not. Without DNA verification at the batch level, you have no way of knowing what you're actually taking. Second, dose. The clinical research showing measurable metabolic results used doses equivalent to 6,000 to 7,200 milligrams of raw Ceylon bark daily. Most capsules contain 500 to 1,500 milligrams of raw powder. That is not a small gap. That is the difference between a therapeutic dose and a decorative amount. Third, delivery. The active compounds in Ceylon are fat-soluble. They need a fat carrier to cross the cell wall and enter the bloodstream. A dry powder capsule has no fat. The compounds reach the gut, find no carrier, and pass straight through without absorbing. The Journal of Food Science and Molecular Nutrition and Food Research both document this clearly. Without a lipid carrier, most of what you swallowed left your body unused. Carol's feet kept going numb on Amazon capsules because what she swallowed was the wrong species at a fraction of the required dose with no delivery system to carry it in. On paper the bottle looked complete. In her body, nothing arrived. That's why four weeks on the capsules did nothing. And four weeks on Metabolae had her feeling cold tile under her feet for the first time in two years. The only one built around all three of those problems was Metabolae. True Ceylon cinnamon. Cinnamomum verum, sourced from Sri Lanka. DNA-verified at the species level, not a label claim, an actual Certificate of Analysis. Dosed at 7,200mg equivalent per softgel using a 12:1 concentrated extract. The dosing range that corresponds directly to the published clinical trials. Suspended in MCT oil from coconuts. Not as a filler. As the delivery system, the fat bridge that carries the active compounds through the cell wall and into the cells where the GLUT4 transporters have been waiting to be woken up. Third-party tested. GMP-certified. Every batch verified. One softgel daily with breakfast, alongside your existing medication. Within the first week, most people report the burning starting to ease and sleep beginning to return. Within the first month, fasting glucose drops. Within 90 days, the monofilament map starts to look different than it did. I've recommended it to dozens of patients in the past five months. Almost all of them are starting to see the burning settle and the feeling begin to come back. Not because I'm doing anything extraordinary. Because the upstream cause is finally being addressed instead of only the signal it produces. Carol hasn't written a night higher than a 3 in three months. Last visit she walked into my office and told me she'd stood barefoot in her backyard and felt the grass under her feet. Her gabapentin is the same. Her dose is the same. The only thing that changed was Metabolae. Her medication was never going to be the full answer. The upstream cause needed something her pills couldn't provide. Metabolae provided it. Your feet don't need another dose increase. They need the upstream cause addressed by the right compound, in the right species, at the right dose, in a delivery system that actually reaches the cells. Not capsules the gut strips out. Not Cassia mislabeled as Ceylon. Not 500 milligrams of dry powder that can't cross a cell wall. Real Ceylon. Therapeutic dose. Fat-delivered. Working alongside your current treatment, not replacing it. Start today. Not next week. Not after your next three-month check. Today. I think about Robert every day. I think about Dorothy. I think about Frank. Don't let your feet become another name on that list. If you are dealing with: Burning in your feet at night that your medication hasn't stopped. Numbness that has climbed higher up your leg in the past year even on a full gabapentin dose. Spots on the monofilament test that registered nothing at your last appointment. Fasting glucose that will not come below 130 no matter what you cut out. An A1C your doctor calls managed while your feet keep sending signals that something is wrong. The fear of where this ends growing louder every time you sit in the podiatry chair. Give it 90 days. Track your fasting glucose every morning. Note your sleep, your burning, the sensation in your feet. Go back for your next appointment. If nothing moves, you get your money back. Ninety-day guarantee. No questions asked. But if it does, if the burning stops waking you, if the monofilament spots start coming back, if your fasting glucose drops to a number you haven't seen in years, if your doctor pauses over your chart and says the word you have been waiting to hear for years, you will understand why I now have a standing conversation with every patient who walks through my door with tingling in their feet. Because Carol did everything right for two years and the burning got worse and the numb patch got bigger anyway. Four weeks on Amazon capsules: nothing changed. Four weeks on Metabolae: she felt cold tile under her feet for the first time in two years. Night burning from an 8 to a 3. Six of ten points felt on the foot exam instead of three. Sleeping through the night. Same gabapentin. Same routine. Different product. Get Metabolae while it is still available. They source verified Ceylon from a certified supply chain in Sri Lanka and produce in small batches. They cannot always keep up with demand. If you see out of stock, sign up for the notification. If it is available, order now. There is a promotion running currently. Three bags at a significant discount, which is the commitment window where the nerve markers actually have time to move. The flood is being managed. The drain was never opened. You know now that it can be. ~ Nurse Sandra Keller, RN, Podiatric Nursing, 31 years
