Your Morning Blood Sugar Isn't Stuck Because You're Doing It Wrong. Your Cells Are Locked.

When Margaret from Leeds sat down with her GP 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 42 mmol/mol — right on the prediabetes threshold. This time it was 45.

"I felt like I'd been told off," she said. "The practice nurse 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 13.6 million people in the UK are at increased risk of type 2 diabetes, with roughly 2 million 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 King's College London, 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.

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 UK-based 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.

Before: Fasting 7.2 mmol/L

Morning readings consistently elevated

After 12 weeks: Fasting 5.8 mmol/L

Self-reported by daily user, retested HbA1c

Research Context

"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."

"My GP 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."

Result: HbA1c 46 → 41 mmol/mol in 14 weeks

"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 7s to 6s within a month."

Result: Fasting glucose 7.4 → 6.2 mmol/L

"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 GP appointment."

Result: HbA1c 44 → 39 mmol/mol; maintained at 6-month retest

"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."

Result: 18 months prediabetic range, no progression to medication

Common Questions

Final Considerations

For those in the prediabetic window — HbA1c between 42 and 47 mmol/mol — 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 GP.

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.
