Your Morning Blood Sugar Isn't Stuck Because You're Doing It Wrong. Your Cells Are Locked.
A look at why proper Ceylon cinnamon — not the cheap cassia filling most capsules — is being studied for its effects on fasting glucose, and what that means for the thousands of Americans watching their HbA1c creep upward.
When Margaret from Chicago sat down with her doctor last autumn, she already knew what the HbA1c result would say. She had cut the biscuits, switched to wholemeal, started walking the dog an extra twenty minutes each morning. Her last reading, six months prior, had been 6.0% — right on the prediabetes threshold. This time it was 45.
"I felt like I'd been told off," she said. "The nurse practitioner said, 'Well, you're not quite at medication yet, but let's see where you are in three months.' Like I was waiting for a train I didn't want to catch."
Margaret's story is not unusual. An estimated millions of Americans are at increased risk of type 2 diabetes, with many already in the prediabetic range. For many, the advice remains consistent: lose weight, move more, eat less sugar. And yet the HbA1c keeps drifting. The cells, it seems, are not responding.

The "Locked Cell" Problem
Dr. Priya Okonkwo, a metabolic researcher at Columbia University, has spent the last decade studying insulin resistance — the condition where the body's cells stop responding properly to insulin, leaving glucose circulating in the bloodstream rather than being absorbed for energy.
The "locked cell" metaphor has gained traction in nutrition research because it reframes the problem: not a failure of willpower, but a biological mechanism that needs the right intervention. For some, that intervention is metformin. For others — particularly those in the prediabetic window, before prescription medication becomes necessary — researchers have been looking at natural compounds that may support insulin sensitivity.
One of the most studied is cinnamon. But not all cinnamon is the same.
Ceylon vs. Cassia: The Cinnamon Most People Are Actually Taking
Walk into any high-street pharmacy or search Amazon for "cinnamon capsules" and the vast majority of what you'll find is cassia cinnamon — Cinnamomum cassia. It's cheaper to grow, more abundant, and has a stronger flavour. It's also high in coumarin, a compound that can stress the liver at the doses typically used in blood sugar studies.
Ceylon cinnamon — Cinnamomum verum, sometimes called "true cinnamon" — contains only trace amounts of coumarin. It also has a different polyphenol profile, including compounds that have been specifically studied for their effects on glucose metabolism.
| Feature | Standard Cassia Capsules | Ceylon + MCT Oil Formula |
|---|---|---|
| Coumarin content | High — liver concern at study doses | Negligible — safe for daily use |
| Polyphenol type | General cinnamaldehyde | Type-A polymers (glucose-specific) |
| Absorption | Powder — often passes through gut | MCT oil softgel — fat-soluble delivery |
| Daily equivalent | 500–1,000 mg (variable) | 7,200 mg fresh cinnamon equivalent |
| Clinical backing | Mixed — often poorly characterised | Standardised extract, batch-tested |
The distinction matters because several studies on "cinnamon and blood sugar" have used unspecified varieties, leading to inconsistent results. When researchers isolate true Ceylon and use standardised doses, the data becomes more interesting — though Dr. Okonkwo is careful to note that no supplement replaces medical care.
Why MCT Oil Changes the Delivery
Even with the right cinnamon, absorption has been a problem. The active polyphenols are not highly water-soluble, meaning much of a powdered supplement can pass through the digestive tract without reaching the bloodstream.
Medium-chain triglyceride (MCT) oil provides a fat-based delivery system. Because MCTs are absorbed directly through the intestinal wall and transported to the liver, compounds dissolved in MCT oil can bypass some of the normal digestive barriers. In supplement formulation, this is known as improving bioavailability — the proportion of a compound that actually enters circulation and can have an effect.

What the Numbers Show
Practs, a US-market supplement company, has formulated a Ceylon cinnamon softgel using organic MCT oil as the carrier. Each softgel provides the equivalent of 7,200 mg of fresh Ceylon cinnamon — a concentration that would be impractical to consume as powder.
The company has collected self-reported data from customers who had their HbA1c retested after three months of daily use. While this is not clinical trial data, the pattern is consistent enough to note.

"The combination of standardised Ceylon extract with a fat carrier is theoretically sound for improving polyphenol absorption. Whether that translates to clinically meaningful HbA1c reduction requires larger controlled trials, but the mechanistic rationale is there."

What Daily Users Report
"My doctor mentioned metformin at my last review. I asked for three months to try this first. HbA1c went from 46 to 41. She said keep doing whatever I'm doing."
"I've bought cinnamon from Holland & Barrett before. Felt nothing. This is different — the MCT oil makes sense when you read about it. Morning readings down from the 130s to the 110s within a month."
"Skeptical as they come. But the 60-day guarantee meant I could get my HbA1c done and still get a refund if nothing changed. It changed. Not dramatically, but enough that I'm not worrying about my next doctor appointment."
"My father ended up on four diabetes medications and still lost his sight. I was determined not to follow that path. This isn't a miracle, but it's part of what's keeping me off prescriptions so far."

Final Considerations
For those in the prediabetic window — HbA1c between 6.0% and 6.4% — the next few years are critical. Research suggests that intervention during this phase can delay or prevent progression to type 2 diabetes. Whether that intervention is dietary change, increased activity, metformin, or a targeted supplement is a conversation for you and your doctor.
What is clear is that not all cinnamon supplements are equivalent. The combination of true Ceylon extract, standardised polyphenol content, and fat-based delivery via MCT oil represents a formulation that aligns with current absorption science. Whether it works for any individual can only be determined by trying it and testing — which is precisely what the 60-day guarantee is designed to accommodate.

Just ordered. My HbA1c was 45 last month and the nurse practitioner started talking about "lifestyle or medication." Giving this three months and getting retested before I commit to long-term medication.
Been on it 6 weeks. Fasting down from 122 to 110 mg/dL. Nothing else changed — same diet, same walking routine. The MCT oil difference is real, I think.
Does anyone know if this affects statins? I'm on atorvastatin and don't want interactions.
Mohammed — no known interaction with statins, but always worth mentioning to your doctor or pharmacist. Ceylon cinnamon is food-derived, not a drug, but it's sensible to keep your prescriber informed.
Bought the Tesco cinnamon capsules for months. Complete waste. Switched to this in October, A1C down from 6.4% to 6.0% at my January check. doctor said "whatever you're doing, continue."
The 60-day guarantee is what sold me. Meant I could get my bloods done and still get a refund if it was rubbish. It wasn't. Just reordered the 3-Pouch bundle.
