The Foam In The Toilet Never Cleared. I Took Ceylon Cinnamon Every Morning For 11 Weeks And Nothing Moved. Then A Supplement Lab Tech Told Me What Was Actually In My Glass.

"I spent twenty six years keeping dialysis machines running for other people. I did everything right for eleven weeks and got absolutely nothing back. It was never my discipline. It was what was in the glass."

Regenis Ceylon cinnamon softgels
I kept these machines running for twenty six years. I was not going to sit down in one.

The morning that ended it started with a toilet I could not stop looking at.

I flushed, and the foam did not go. It sat there on top of the water. Thick, white, still sitting there when I came back in to brush my teeth.

I knew exactly what I was looking at. That is the part I cannot tell you was a shock.

Hello, I'm Dean Marchetti. I'm 61, and for twenty six years my job was keeping dialysis machines running.

Not as a nurse. As the technician. I calibrated the pumps, changed the filters, ran the tests and signed the log taped to the side of every chair on that floor. I know what a renal unit sounds like at six in the morning. I know what four hours in one of those chairs does to a person's face, because my father spent the last four years of his life in one. Three days a week. Same unit I worked in. Some of those machines I had serviced with my own hands.

So when my doctor turned her screen around and walked me through a set of results that had been drifting the wrong way for two years running, nobody had to explain any of it to me gently. I had already watched the entire movie. I knew how it ended.

My ankles were puffing over my socks by dinner. I was up two and three times a night. I was walking into a wall at three every afternoon that no amount of sleep touched. And a week after that appointment, what she had said in it was still sitting in my chest: if this trend holds, we need to have a different conversation. She wanted me back in six months.

I knew which conversation. Or I was sure I did, which at six in the morning is the same thing.

So I did what a technician does. I went and read the actual research. Real journals. Ceylon cinnamon, insulin sensitivity, the GLUT4 transporters that pull sugar out of the bloodstream and into the cell where it belongs. The logic was clean. Less sugar circulating, less pressure through the filters. I wasn't hoping. I was convinced.

My wife Renata found a dosing guide on a health blog. Two heaping teaspoons of organic Ceylon powder every morning. We ordered a two pound bag online and it turned up in three days. Kraft paper, the word Ceylon printed right there on the front in a handsome serif.

Eleven weeks. Seventy seven mornings. Two teaspoons into the blender with a banana and almond milk, thirty seconds on high, and the powder never once fully dissolved. There were always clumps. Gritty, chalky ones that settled at the bottom of the glass and went down last, coating the back of my throat like wet sand. By week three the smell of cinnamon at six in the morning turned my stomach before I picked the glass up.

I kept a notebook on the kitchen table. Date on the left, and a second column with one word in it.

Week 1: Foam.

Week 4: Foam.

Week 11: Foam.

Seventy seven mornings of doing everything right, and the only word in that column never changed once. My ankles still hung over my socks at dinner. I was still up twice a night. Three in the afternoon still took my legs out from under me. A blender stained brown in the seams that no amount of scrubbing would clear, and every single morning before any of it, that foam sitting on the water, waiting for me.

That morning I opened with, the one I stood there staring at, was morning seventy seven.

I finished the eleventh week anyway, because I am the kind of man who finishes things. Then I poured what was left of the bag into the bin.

What I did not know yet, and would not find out until that Saturday at a farmers market, was that I had never actually taken Ceylon cinnamon at all. Not once. Not the way the studies mean it.

If any of this sounds familiar:

  • Foam in the toilet that is still sitting on the water when you come back
  • Ankles and sock lines that feel tighter by the end of the day
  • Two or three trips to the bathroom every night, every night
  • A last check-up where your doctor said she wants to keep an eye on something
  • Cravings, and a fog that does not lift until mid morning no matter how carefully you ate
  • A wall around three in the afternoon that sleep never fixes
  • A cabinet full of cinnamon powder, capsules and gummies that did nothing

And if none of that is you yet, that is the best news on this page. Every one of those things creeps quietly for years before anybody says a serious word about it, and the creeping years are the ones a person can still do something about. If you are in those years right now, you are early. I was not.


It happened at a farmers market that Saturday, a few days after the bag went in the bin.

There was a woman at the spice booth telling the man ahead of me why she would not buy the jar he was holding. She wasn't performing. She sounded tired about it. When he moved off I asked her how she knew all that, and she said she runs assays on supplement raw material for a living, and that she has had this conversation at that booth more times than she can count.

So I told her what I had been doing. Eleven weeks. Two heaping teaspoons every morning. The clumps, the notebook, the one word that never changed.

She did not ask me one single question about my discipline. She asked what species it was. She asked where it came from and whether it came with a certificate. Then she asked how long that bag had been sitting open on my counter.

I could not answer the first two at all, and I answered the third one without understanding why she was asking.

Wrong species. Unknown strength. And a form that was quietly falling apart in my own kitchen. Three failures stacked one on top of another, in a glass I had been choking down at six in the morning and feeling disciplined about. Four minutes is all it took her, standing between a tomato stand and a spice booth while I held a paper bag of heirloom tomatoes I had completely stopped caring about.

Below are the 7 things I know now, starting with the one nobody selling cinnamon powder wants to explain.

Verified Sri Lankan Ceylon, Not Cassia Wearing A Ceylon Label

She said it the way a person reads out a weather report. Over 70 percent of what gets sold as Ceylon in this country is partly or entirely cassia. I asked her to say it again. She said it again, in exactly the same voice, because in her lab that isn't news. That's a Tuesday.

Cassia is a different species entirely. Different bark, different chemistry, and a fraction of the price, which is the whole reason it ends up in the bag with somebody else's name printed on the front. And the difference that mattered most to her was coumarin. She told me cassia can carry up to 250 times more coumarin than true Ceylon, and that coumarin at daily supplement doses is not something she would want her own liver processing for eleven weeks straight.

Then she said the sentence I did not expect from a stranger at a spice booth. Tell your doctor you swallowed an unverified powder every morning for eleven weeks, and ask her to check your liver. I did exactly that at my next appointment. It is not a detail I would ever have thought of on my own, and I am glad somebody made me.

I still had the bag. I had emptied the powder out but the bag itself was folded flat in the recycling in the garage, and I went out and got it. Organic. The word Ceylon in that serif. Not one word about species verification anywhere on it. No certificate, no lot code, nothing I could have checked even if I had known to check.

My working life was spent signing calibration logs. If the log on the side of a machine wasn't signed, that machine did not run that day. No exceptions, no arguments, no matter who was waiting. Nobody on that floor ever accepted "it says so on the label" as evidence of anything. And there I was, swallowing an unverified brown powder every morning on exactly that standard, because somebody had printed the right word in the right font.

The bottle sitting on my counter now says Cinnamomum verum, Sri Lanka, with a batch number printed on the side. Regenis verifies the species batch by batch, and I looked mine up before I swallowed the first one. That is the actual difference, and it is smaller and more boring than people expect. One of those two labels can be checked. The other one can only be believed. I spent eleven weeks believing.

Species was the first of the three things I had wrong. Looking back, it was the smallest one.

One Softgel, A Measured 12:1 Extract, Because Ground Bark Is Never The Same Twice

For a while after that Saturday I assumed she had been telling me I hadn't taken enough. That would have been the easy answer, and honestly it would have let me off. She was telling me something worse. She was telling me I had no idea what I had taken.

A teaspoon of cinnamon powder is ground tree bark. Bark is a crop. What's in it moves with the harvest, with the age of the tree, with which layer got ground up, with how it was dried and how long it sat in a warehouse through a hot month. Two scoops out of two different bags can be two genuinely different products with the same word on the front.

Ceylon cinnamon bark compared with a measured extract softgel
Bark is a crop. An extract is a measurement. That is the whole distance between the bag and the bottle.

So those seventy seven mornings were never a dose. They were seventy seven guesses that happened to look identical in the glass. I had a notebook full of dates and one repeated word, and what I had not understood until that morning at the market was that I could not have told you what I was even testing. That is not discipline. That is a man scooping.

An extract is a different object altogether. You start with a known weight of verified bark, pull the actives out of it, and then measure what actually came out. A 12:1 concentrate means twelve parts bark went in and one part standardized extract came out, and what goes in the softgel is measured rather than scooped. Every softgel in the bottle is the same as the one before it, and the bottle I open next year is the same as this one. A paper bag has never once been able to promise that and it never will.

Here is the whole of what my bottle claims, in the order it prints it. Ceylon cinnamon extract. Cinnamomum verum. 12:1 concentrate. 7,200mg raw bark equivalent per softgel. Batch number. Batch date. That is a specification. The bag had a serif font and the word organic. The same measured amount in every softgel and every batch is not a dramatic promise, and I'm not going to dress it up as one. It is the least I should have demanded of myself before I gave eleven weeks of my life to it.

And even a verified species at a measured strength can be wrecked before it ever gets near you, by something as unremarkable as the bag it is sitting in.

A Sealed Softgel In MCT Oil, Because An Open Bag Of Powder Is A Different Product Every Week

This is the question of hers I did not see coming. Not what I took. How long the bag had been open.

Two pounds of ground bark is a lot of mornings. Mine sat on the counter next to the toaster from the first week of it to the last, opened and re-opened seventy seven times, in a kitchen that gets sun through the window and steam off the stove. Cinnamaldehyde, the compound that gives the bark its smell and most of its reputation, is volatile. Air takes it. Light and heat take it faster.

So the bag I opened in week one was not the bag I was scooping out of in week eleven, and there was no way on earth I could have told the difference by looking. It looked identical. It smelled like cinnamon the whole way down. Ground bark smells like cinnamon long after the part you actually wanted has gone up into the room.

I told her, a little defensively, that at least I always took it with food. She said food was not the issue. The issue was that I had no idea what was left in the powder by the time it went in. She wasn't unkind about it. She just said it the way you'd tell somebody their tire was flat.

That is a technician's nightmare, by the way. I spent my career finding out why equipment that passed every visual inspection was doing nothing at all, because the part that mattered had quietly degraded inside the housing where nobody could see it. Every gauge reading normal. Everything looking right. Nothing happening. I chased that failure for twenty six years and it never once occurred to me to look for it on my own kitchen counter.

What she told me to go looking for was a sealed single serving. Not a scoop out of a bag that has been breathing since March. An extract suspended in MCT oil and sealed into a softgel, away from air and light, so the thing I swallow in month six is the same thing I swallowed on day one. That is what the Regenis softgel is, and it is the specific reason I take that one.

And here is the thing I underestimated completely. The ritual is gone. One softgel with breakfast, thirty seconds, done. No two pound bag, no measuring spoon, no blender screaming at six in the morning, no gritty glass and no brown rings to scrub out of the seams. My kitchen stopped smelling like a spice factory. The blender is out in the garage now with the Christmas lights.

Getting the real thing in was the whole problem. But it only matters because of what the compound is supposed to do once it is in there, and that part, the one single thing in this entire mess, I had actually had right from the beginning.

What The Research Is Actually About, And Why I Was Exhausted An Hour After Eating

For about a year before any of this I had been telling myself a story about being 61. The wall at three in the afternoon. The fog that didn't lift until ten in the morning. I would sit down at the kitchen table after lunch and it was like somebody had pulled my plug out of the wall. I used to think that was just what 61 felt like.

What never made sense to me was that it was happening straight after I had eaten. I had just put fuel in. An hour later I could barely keep my eyes open at my own table.

Illustration of glucose entering a cell through GLUT4 transporters
The doors have a name in the research. GLUT4 transporters. Nobody had ever put it to me that plainly.

Here is the explanation, and it is the only piece of this I had right all along. Every cell in my body has doors on it. When insulin knocks, those doors are supposed to open and let glucose in, out of the blood and into the cell where it turns into energy. The doors have a name in the research. GLUT4 transporters.

Insulin resistance is what happens when insulin knocks and the doors are slow to answer. The pancreas responds by shouting louder, pushing out more insulin, and the doors still drag. And this is the part I don't think most people are ever told plainly: the sugar that doesn't get into the cell does not disappear. It stays in circulation. It goes around, and around, and around.

That, I came to believe, was my three o'clock. Not 61.

Ceylon cinnamon contains a family of polyphenols that have been studied for their effect on GLUT4 activity and insulin sensitivity. Not for shutting anything down, and not for masking anything. For the doors. That is why the research on this spice sits in real journals with real methods sections, and it is why I believed in it enough to choke down seventy seven glasses of wet powder without ever once questioning the glass.

I was right about the compound the entire time. I was wrong about every other thing in that glass. That is a strange feeling to sit with in a parking lot with a bag of tomatoes on the passenger seat. It was also the first time in two years I had felt anything other than resigned.

And where all that circulating sugar goes while it waits is the reason this was never really a blood sugar story for me.

The Filters: Why This Was Always A Kidney Story

About 200 quarts of blood pass through a pair of kidneys every day. Inside each one sit roughly a million microscopic filters called glomeruli, and their entire job is to let waste and water out while holding protein and blood cells in.

Now push sugar loaded blood through filters that fine, hour after hour, year after year. It is sand going through the finest mesh screen I have ever seen, and I have spent my life around fine mesh. Nothing dramatic happens on any given Tuesday. It happens slowly and quietly for years, which is exactly why people find out late.

When those filters stop sealing the way they should, protein can slip through into the urine. That can be one reason for foam. There are perfectly harmless reasons for foam as well and I want to be fair about that, and I am a technician and not a physician, so I asked mine rather than deciding on my own. But I spent my working life on the machines that do the filtering when a person's own filters have quit, and you learn very precisely what the machine is standing in for.

So I reasoned it backward, and I will own that it was my reasoning and not anybody's prescription. Less sugar going around in there, less of that going through the mesh. That is why I went looking at a spice instead of buying a bigger water bottle. Everybody kept telling me to hydrate. Water was never the thing wearing those filters out.

For me, the powder never touched any of it. Eleven weeks, foam every single morning, one word in the notebook. On the softgels, nothing happened at all for the first stretch, which I expected, because by then I had stopped expecting anything. Somewhere near the end of the second week it looked thinner. I told myself I was imagining it, because I had earned the right to be cynical. In the fourth week I flushed and the water was just clear.

I stood there at six in the morning staring into a toilet bowl like a fool. Then I sat down on the edge of the tub and put my head in my hands for a minute. That is my own experience and not a promise to you, and individual results vary. But it was the first thing in two years that had gone the right direction.

The foam was mine alone. I watched for it at six in the morning and I never said one word about it to anybody. The two things that came after it were the ones I could not keep to myself.

The Two Things Renata Noticed Before I Did

The foam was week four. Everything else took a good deal longer than that, and that is the honest part of this. Nothing announced itself and nothing happened in a week. Renata got to both of them before I did.

The first was the middle of the night. For well over a year I had been getting up two and three times, and after a while you stop counting that as a symptom and just count it as your life. Somewhere around the fifth or sixth week I slept the whole way through. I assumed it was a fluke. It happened again the next night, and the night after that. Renata was the one keeping score. She said it from the sink without turning round. "That's four." I had never told her I was counting. She had been counting.

One Regenis softgel taken with breakfast
One softgel with breakfast. Thirty seconds. The whole morning ritual, start to finish.

The second was my ankles. By dinner they used to hang over the tops of my socks, and there was a ridge pressed into the skin when I pulled them off at night. I noticed because my work boots went on the way they used to, without me sitting on the step and working at them first. Renata noticed because the ridge wasn't there.

And underneath both of them, the thing I had given up on entirely. Three in the afternoon stopped taking my legs out. Not a jolt, nothing like caffeine. I just got to the end of a day and found I still had some of it left. I stopped reaching into the cupboard at four o'clock for something sweet, which I had been doing for years and calling a habit.

She stood in the kitchen doorway on a Sunday morning while I was making coffee and said, carefully, "You seem different." I said I felt different. That was the whole conversation, and neither of us wanted to touch it any harder than that. Eleven weeks of powder had beaten the hope out of both of us and I was not going to raise hers again for nothing.

No cramping either, no urgent trips to the bathroom, nothing I had to schedule my morning around. It is a spice extract suspended in oil, taken with breakfast. Individual results vary, and Renata is not a laboratory.

None of that is proof though, and I know that better than most. I spent my career around people who felt perfectly fine and had results that said otherwise. Which is why the thing that actually decided it for me was not anything I felt at all. It was a document.

Third-Party Tested Every Batch, And What My Doctor Said At The Follow Up

Start with the boring part, because for me it was the deciding part. Regenis publishes third-party lab testing on every batch. Species verification, active compound concentration, heavy metal screening, a certificate of analysis tied to the batch number printed on the bottle.

My two pound bag had none of that. No certificate, no species test, no potency assay, no way on earth to know what was in it. And I want to be blunt about what that actually means, because I lived inside it for eleven weeks. Powder is not one product. It is a slightly different product every morning, dressed up in the same glass.

Then the follow up came around, the one she had booked six months earlier. I had been on the softgels about thirteen weeks by then. I worked that out on the drive over and did not particularly enjoy the arithmetic, because it meant the first quarter of that six months had gone into a bag of powder that gave me nothing.

The nurse drew blood and I sat in that room for twenty minutes with my hands flat on my knees.

Things had moved in the right direction, and she was pleased. I am not going to print my results on an advertisement, and I would not trust a page that did. She was measured about it, the way good doctors are. She said one set of results is one set of results and she wanted to see the next one before anybody got excited.

Then she asked what had changed, and I told her all of it. The species I could not verify. The strength I could never have known. The bag that had been breathing on my counter since March. She listened and took notes, and she said the research on Ceylon cinnamon and insulin sensitivity is real research and that she had read some of it herself. She told me to keep taking everything she already had me on, to keep writing it all down, and to come back in twelve weeks. I do all three.

I sat in that parking lot afterward with both hands on the wheel for a long time. My father used to sit in his car in the lot outside that unit for five minutes after he had already parked it, and I saw him do it more than once, and I never asked him why. Sitting there with my own keys in my hand, I understood it. Twenty six years I kept those machines running for other people. I intend to do everything in my power never to sit down in one.

That is my experience and not a promise about yours. Individual results vary. But it was never my discipline. It was what was in the glass.

So if you're where I was, with the foam and the flat weeks and an appointment already circled on the calendar, I have one piece of advice and it is not about which bottle to buy. Get a notebook first. A cheap spiral one. Write the date and whatever it is you are watching, every morning, before you take anything, so that in three months you are reading your own handwriting instead of trusting your memory. Then give the right form ninety days, because almost nothing I noticed showed up inside the first fortnight. There is a ninety day guarantee that runs about that long. And take everything your doctor has prescribed you, exactly as she prescribed it, and talk to her before you add anything or change anything. That last one is not advice from me. That is just how this works.

I am not going to invent a warehouse fire for you. Here is the only urgency that was ever real in my case: the drifting years are the ones you can still do something about, and every morning spent on a powder you cannot verify is a morning off that clock. I lost seventy seven of them, and there is a ninety day guarantee on this, which means the only thing you are genuinely risking is finding out.

I had a bag of powder open on my counter since spring and thought I was being disciplined about it. The softgel is a completely different experience. No blender, no grit, and the afternoon wall has stopped arriving.

Halbert N., Cedar Rapids, IA Verified buyer

Ordered it for my husband and started taking it myself. The line about ankles printing a ridge into the skin by dinner was the sentence that made me pay attention. That has quietly stopped happening here.

Vonetta S., Fayetteville, NC Verified buyer

Nothing at all for the first fortnight, so be patient with it. What sold me was the batch number on the side. I looked it up before I opened the bottle, which is more than I could do with anything else in my cupboard.

The notebook column with one word in it is what did me in. My husband has three months of readings written down and every single line says the same thing. Nobody has ever once asked him what was actually in the powder.

Same in this house. As the article says, they were seventy seven guesses that happened to look identical in the glass. I had never thought about it that way and now I cannot stop.

Went and got the jar out of my pantry after reading item one. No species anywhere on it, no lot code, nothing. As the article says, one of those two labels can be checked and the other one can only be believed. Mine can only be believed.

Exhausted an hour after eating. I have been describing that to people for two years and getting shrugged at. Item four is the first time anybody has explained to me why it happens right after a meal instead of before one.

Yes. As the article says, the doors have a name in the research, GLUT4 transporters. I actually went and looked that up afterwards and it is a real thing with real papers behind it.

The question about how long the bag had been open stopped me cold. Mine has been sitting next to the kettle since February. It never occurred to me that it was not the same powder now as it was then.

My mother is on dialysis and I read the part about his father twice. The line about hydration is the one that stung, because that is all anybody has ever told us. As the article says, water was never the thing wearing those filters out.

Gave up on cinnamon two years ago after choking down the gritty stuff every morning and getting nowhere. As the article says, it was never my discipline, it was what was in the glass. That is going to sit with me for a while.

Honestly the part I liked best was the advice at the end. Get a notebook first, write it down before you take anything, then give it ninety days. Nobody selling anything usually tells you to start by measuring yourself.
