My 30-Day Glucose Diary: How I Went From 6.4 to 5.6 Without Medication
By Karen M., 58, retired teacher, Scottsdale, AZ • Updated June 2026
When my doctor told me my A1C was 6.4, she said three words that changed everything: "We need to talk about metformin."
I was not ready for that conversation. I am 58 years old. I walk every morning. I eat well, or at least I thought I did. And suddenly there was a number on a chart and a word in my file that made the future I assumed I had feel like it had a question mark over it.
"Prediabetic." I did not sleep for three nights after that appointment.
My doctor gave me six months before we would have the medication conversation for real. Six months to bring my numbers down on my own. She told me to watch my diet and exercise more. She did not give me a plan. She did not give me tools. She sent me home with a destination and no map.
So I did what everyone does. I Googled at 2am. I cut carbs. I walked more. I bought three different cinnamon supplements from Amazon and took them every day for four months. My A1C went from 6.4 to 6.2 and stuck there.
I was doing everything right. The number would not move.
The Thing Nobody Told Me About Cinnamon
I was ready to give up on supplements entirely when a friend, a nurse practitioner, looked at the cinnamon bottles in my cabinet and said something I had never heard before.
"Karen, this isn't even cinnamon. Not the kind that matters."
She explained that over 90% of what's sold as "cinnamon" in the US is actually Cassia, a different species entirely. Different plant, different chemistry. The studies that show real effects on blood sugar used Ceylon cinnamon (Cinnamomum verum), at a concentrated dose, in a form that actually absorbs.
What I had been taking for four months was the wrong species, at a fraction of the studied dose, as dry powder that mostly passed through me. Three failures stacked on top of each other.
I did not fail. The product failed me.
She showed me a product she had been recommending to patients with similar numbers: a DNA-verified Ceylon cinnamon extract, concentrated 12:1 at a clinical dose, suspended in MCT oil for absorption. One softgel a day. She said to track my morning fasting glucose every day and keep a diary.
So I did. Here is exactly what happened, day by day.
The Diary
First morning. Took my reading before coffee, like always. 142. That is where it has been sitting for months. Took the first softgel with breakfast. No taste, no stomach issues. Easy.
Still in the same range. Not expecting anything yet. My friend said to give it time and not watch the number daily for meaningful changes. "The trend matters, not the dots." Hard advice to follow when you check every morning.
First morning under 135 in weeks. Could be noise. Could be real. My post-meal reading after lunch was 156, which is lower than my usual 170s. I am trying not to get excited.
Two weeks in. The trend is undeniable now. My 7-day average dropped from 141 to 131. I ate pasta on Tuesday, the first time in months, and my post-meal was 162 instead of the 185+ it used to be. Something is different.
I stared at the glucometer this morning. 119. Under 120 for the first time since my diagnosis. My 7-day average is 124. I called my friend the nurse and she said, "Keep going. The 8-to-12-week window is where the real change compounds." I am keeping this diary in a notebook now. I want to walk into my doctor's office with it.
One month. My 7-day average is 116. My post-meal readings are consistently in the 130–145 range instead of the 170–190 range they were before. I have not changed my diet beyond what I was already doing. I have not walked more than usual. The only thing that changed is the cinnamon.
The Doctor's Appointment (Week 10)
I walked into my 10-week check-up with my diary in my hands and my glucometer in my bag. My doctor ran the labs.
A1C: 5.6
Down from 6.4 to 5.6 in ten weeks. Normal range. No medication.
My doctor looked at the number, looked at me, and said: "What did you change?"
That question, "what did you change?", is the moment I had been working toward since the day she first said the word "prediabetes."
I showed her the diary. I showed her the product. She looked at the COA, looked at the species verification, and said: "Keep doing whatever you're doing."
| Metric | Before | After (10 Weeks) | Change |
|---|---|---|---|
| A1C | 6.4 | 5.6 | ↓ 0.8 points |
| Fasting Glucose (avg) | 142 mg/dL | 108 mg/dL | ↓ 34 mg/dL |
| Post-Meal (avg) | 178 mg/dL | 138 mg/dL | ↓ 40 mg/dL |
| Morning Readings <120 | 0 of 30 | 26 of 30 | 87% of mornings |
What I Wish Someone Had Told Me on Day One
I spent fourteen months and over a thousand dollars doing everything right with the wrong tools. Cutting carbs, walking, buying grocery-store cinnamon that turned out to be the wrong species at the wrong dose in the wrong form.
Diet and walking are the floor. You should do both. But they fix the glucose coming in. They do not fix the part that was actually broken, the insulin signalling, the receptor that stopped answering properly. That is why you can cut every carb, walk every day, lose weight, and still plateau in the low 6s.
The three things that were wrong with my old cinnamon:
1. Wrong species. Cassia, not Ceylon. Different plant, different active compounds.
2. Wrong dose. Raw powder at 500mg, not a 12:1 concentrated extract at a clinical dose.
3. Wrong delivery. Dry powder that passed through me. Not MCT-oil-suspended for absorption.
When I corrected all three, real Ceylon, real dose, real delivery, the number that had been stuck for fourteen months started moving within the first two weeks.
The Product
The product that changed my numbers is Metabolae Ceylon Cinnamon. Here is what makes it different from the bottles in your drawer:
DNA-verified Ceylon cinnamon (Cinnamomum verum), not Cassia. Verified and published.
12:1 concentrated extract at a clinically relevant dose per softgel.
MCT oil suspension for lipid-based absorption, it actually gets into your system instead of passing through.
One softgel a day. No taste, no stomach issues, no complicated protocol.
Published Certificate of Analysis, species ID, active assay, coumarin, heavy metals. You can request your batch number before you order.
“I showed my doctor the COA and the species verification. She said, 'This is the first supplement a patient has brought me that I can actually evaluate.' That was the moment I knew this was different.”— Karen M.
