Dr Henry Caldwell, GP

You have a cabinet full of them. CoQ10. Fish oil. Alpha lipoic acid. A generic kidney blend someone recommended. A cinnamon capsule from the health food shop that someone in a forum said changed their numbers. You take them every morning. You set them out the night before so you do not forget. You buy the good ones, not the cheapest versions. You read the labels. You do everything a responsible person does when they are trying to take care of themselves. And every time you go back for blood tests, the numbers are still moving in the wrong direction. You are not being careless. You are not being lazy. You are trying harder than most people would. And it is not working. That is not a supplement problem. That is a question nobody has answered for you. Not what to take. But why none of it is reaching the thing that is actually putting pressure on your kidneys. And until someone answers that question, you can fill that cabinet with every well-reviewed product on Amazon and your eGFR will keep dropping a point each quarter. I'm Dr Henry Caldwell. I've been a consultant nephrologist, a kidney specialist, for 20 years. I've watched blood sugar damage kidneys from the inside out. I've sat across from patients and explained what dialysis means. I've watched people lose toes. I've watched people lose vision. I've watched a man cry when I told him his kidneys were at 28 percent. And for most of my career, when a patient pulled a supplement out of their bag and asked me what I thought, I would smile, document it, and tell them to keep taking their prescribed medicine. I was wrong to do that. Not because the supplements were hurting them. Because I knew what their kidneys were actually up against and I knew those supplements were not getting close to it. And I never told them that. Six months ago, a patient set a bag on my desk. Ceylon cinnamon. Concentrated extract. 7,200mg equivalent in MCT oil. Called Glissé. Three months later his eGFR had climbed from 46 to 54. His urine protein had dropped from 58 mg/mmol to 22 mg/mmol. That night I went home and started reading everything I had never taken the time to read. About what every supplement my patients had been bringing me for years was actually doing, or failing to do, and why. Here is what your cabinet full of supplements is missing. The foam in your toilet every morning. The tingling that never leaves your feet. The fatigue that settles in before noon. The swelling that leaves sock marks on your ankles. The waking up at 3am to use the toilet. These do not feel like a single problem. But they are not separate problems. They are one problem showing up in different places. Your HbA1c measures one thing. A rolling picture of how much sugar has been in your blood over the last few months. That is all it measures. It does not see the tiny capillaries threading through your kidney tissue. It does not see the sustained pressure those filters have been under for years. It sees the level of the flood. Not where the flood is going. Every cell in your body has transporters on its surface. GLUT4 transporters. Their job is to open when insulin signals them, grab glucose from the blood, and pull it inside the cell where it gets converted to energy. In a healthy body that sequence is automatic. Insulin signals. Doors open. Glucose moves from blood into cell. Blood sugar comes down. In insulin resistance -- the thing underneath type 2 diabetes -- those doors stop responding properly. They are still there. They just stopped coming to the surface. Insulin gives the signal. Nothing happens. Your pancreas sends more insulin. Still nothing. The glucose has nowhere to go, so it stays in your blood and keeps circulating. Your cells are starved of energy. Your blood is flooded with glucose. Think of it like fine sand moving through a water pipe. It does not crack the pipe in one event. It makes no sound. It just grinds the inside walls thinner, grain by grain, until one day the pipe starts to fail in ways you cannot see from the outside. Your HbA1c is reading the water pressure. It is not reading the pipe walls. The foam in your toilet is made of pipe walls. So that is why the CoQ10 did not move your kidney markers. It does not open the doors. Much of it struggles with absorption and may never reach kidney tissue at meaningful levels. It addresses damage further down the line while the real pressure is still running upstream. That is why the fish oil did not move them. It may support general inflammation, but it does not touch the GLUT4 transporters. It does not stop glucose staying in your blood and moving through your kidney capillaries hour after hour. One consequence managed. The cause untouched. That is why the alpha lipoic acid did not move them. Better than the others, and it does get into cells. But it works broadly. The doors are still closed. And that is why the cinnamon capsule from the health food shop did not move them. This one was pointing at the right mechanism. But it failed at the delivery. Most cinnamon sold in supplements is cassia bark. A completely different plant from true Ceylon cinnamon. Same look. Similar smell. Completely different chemical profile. At the doses required to actually affect blood sugar, cassia can put strain on your liver because of its coumarin content. You were not taking the wrong amount. You were taking the wrong plant. And even if you found real Ceylon cinnamon, a dry powder capsule often does very little. The active compounds are fat-soluble. Your cell walls are a double layer of fat molecules. Fat-soluble compounds need fat to pass through them properly. A dry powder capsule has no fat carrier. The compounds reach the gut, find no carrier, and can pass through without ever reaching the cells that needed them. So that is why none of it moved. Not because you chose wrong. Not because you were not trying hard enough. Because every one of those products was working on a consequence of the problem instead of the mechanism behind it. And the one pointing at the right mechanism was failing at delivery. You were not failing the process. The products were failing to reach the problem. Here is what stopped me cold at midnight, reading in my study with 18 years of nephrology behind me. The research on how to open those doors exists. It has been published. Peer-reviewed. Sitting in databases that a short NHS appointment leaves no time to read. There is a specific compound in true Ceylon cinnamon that supports GLUT4 transporters directly. It goes to the cell, speaks to the machinery inside it, and helps wake the doors back up. Not by forcing more insulin into an already overwhelmed system. By going around the broken signal and supporting the cellular machinery that was always supposed to open the doors. When the doors open, glucose begins clearing from the blood into the cells. The pressure drops. The sand slows in the pipe. The kidney filters face less sustained assault. The protein leakage drops. The foam disappears. The drain opens. Your medicines manage the flood. This opens the drain. In 18 years of practising nephrology, not once had I mentioned it. You cannot patent a bark compound in the same way you can patent a drug. So no pharmaceutical company funds the kind of trials that would land it in every consultant’s inbox. The studies stay in databases. The patients keep filling their cabinets with CoQ10 and fish oil and watching their eGFRs drop another point each quarter. That is not your fault. The system was only giving you half the answer and never telling you the other half existed. The patient who set the bag on my desk had found the other half. He was taking Glissé. That is the logical next step once you understand the mechanism. The right plant. The right concentration. A delivery system that actually carries fat-soluble compounds through your cell walls. Glissé is true Ceylon cinnamon, Cinnamomum verum, sourced from Sri Lanka. DNA-verified at the species level -- not just a label claim, an actual Certificate of Analysis. Dosed at 7,200mg equivalent per softgel. A 12:1 concentrated extract, the dosing range that matches the published clinical research. Suspended in MCT oil from coconuts -- not as a filler, as the delivery system -- the fat bridge that carries the active compounds through your cell wall and into the cells where the GLUT4 transporters have been waiting for years to be told to surface. Third-party tested. GMP-certified. Every batch verified for purity, potency, and coumarin levels. It comes in a bag, not some bulk bottle. A study published in the Journal of the American College of Nutrition found that the active compounds trigger the same internal chemical cascade that insulin is supposed to trigger, and were 20 times more effective at activating this pathway than any other natural compound tested. Twenty times. A second study confirmed that Ceylon extract physically increases the number of GLUT4 transporters at the cell surface. The doors do not just crack open. They multiply. I went home that night and ordered one. Week 1, my energy levelled out. I had a fasting blood glucose stuck at 6.2 mmol/L for two years -- not alarming, but not moving. What I noticed first was not the meter. It was that I stopped hitting the wall at 2pm. Just steady, clear energy from morning through evening. Week 2, my fasting blood glucose dropped from 6.2 to 5.4 mmol/L. I tested three times. Week 3, the 3am trips to the toilet stopped. I was sleeping through the night for the first time in over a year. Week 8, my fasting blood glucose was consistently between 5.1 and 5.6 mmol/L. Week 10, my colleague ran my blood tests. My creatinine came back at 88 µmol/L. It was 115 six months earlier. He looked at it. Looked at me. "What did you change?" I handed him the research. He read for ten minutes. Closed the folder. "Your kidney function improved." "Keep doing whatever you're doing." That patient came back for his follow-up. eGFR at 54. Up from 46. Urine protein at 22 mg/mmol. Down from 58. "Your numbers are improving." He smiled. "The drain opened." I have recommended Glissé to nine patients now. Every single one has come back and reported the same pattern. Better sleep within the first week. Steady energy through the day. Lower fasting glucose within the first month. One patient -- a 61-year-old woman with protein leakage that had been climbing for three years -- came back at her 90-day follow-up with urine protein down 40 percent. She cried when she told me the foam in her toilet was gone. If you have been taking CoQ10, fish oil, alpha lipoic acid, or generic cinnamon capsules and your kidney markers are still moving in the wrong direction, try Glissé risk-free. Ninety-day money-back guarantee. No questions asked. If your fasting glucose does not come down, if your kidney markers do not move, if you see no difference in 90 days, you pay nothing. Most patients who see real movement in their kidney function committed to at least three months. That is how long it takes to give your eGFR a real chance to stabilise and shift. The 90-day guarantee means those three months cost you nothing if the numbers do not move. Here is what happens if they do. Your fasting glucose starts dropping between weeks 2 and 4. Your sleep improves within the first week. Your energy levels out through the day. And at your next blood test -- the one where your doctor has been saying let's keep an eye on it for two years -- she pauses. Looks at the numbers. Looks at you. Asks what you changed. You tell her. She is quiet for a moment. Then she uses a word you have not heard in years of appointments. "Improving." Not managed. Improving. One softgel daily with breakfast. That is the whole protocol. They sell out. It is a small company sourcing verified Ceylon from Sri Lanka and doing it properly. I have had patients wait weeks when they sold out. If it is available, order now. If you are dealing with foam in the toilet that will not go away, tingling in your feet your doctor calls neuropathy, fasting blood glucose that will not come below 7.2 mmol/L, or eGFR dropping a point or two every time you go back for blood tests, give it 90 days. Track your fasting glucose every morning. Go back for your next blood tests. If the numbers do not move, you get your money back. But if they do -- if your protein leakage drops, if your eGFR holds or climbs, if your doctor pauses over your blood tests and says the word you have been waiting to hear for years -- you will understand why I now have a standing conversation with every type 2 patient who walks into my clinic. The flood is being managed. The drain was never opened. You know now that it can be. ~ Dr Henry Caldwell, Consultant Nephrologist, 20 years
