I Tracked My Blood Sugar on Metformin for 6 Weeks. Then I Switched to Ceylon Cinnamon. Here's What Happened.
Same timeline. Same person. One moved my A1C 6 points. The other moved it 18 — with zero side effects. My doctor pulled both results side by side and asked: "What brand?"
Six weeks on Metformin. Fasting blood sugar started at 182. By week six, it had barely moved — plateaued at 169. A1C improved from 8.9 to 8.3. Six points. The doctor called it progress. I felt worse than when I started.
Then I ran the same six-week experiment with Ceylon cinnamon extract and MCT oil. Week one: 179. Week six: 121. A1C went from 8.9 to 7.1. Eighteen points. No stomach cramping. No brain fog. No reaching for Tums after every meal. The first time under 130 in two years — and I tested three times to make sure the meter wasn't broken.
When my doctor laid both sets of results side by side, he didn't say anything for a moment. Then he looked up and said: "Metformin moved you six points in six weeks with side effects. This moved you 18 points with none. What brand are you using?"
The brand was Resia. And what I didn't understand at the time — what most people managing blood sugar never get told — is why the form of cinnamon matters as much as the cinnamon itself. This article explains the mechanism, the numbers, and why most cinnamon supplements on the market are designed to fail before they even reach your bloodstream.
Why Metformin Stops Working — And What Nobody Tells You
Metformin works by suppressing the liver's glucose output. It's a symptom manager — it reduces how much sugar your liver dumps into the bloodstream, which lowers your fasting numbers. For many people, it works reasonably well in the first few weeks.
But here's what the prescription doesn't come with: a warning that it plateaus. Because Metformin doesn't address why your cells stopped responding to insulin in the first place. It doesn't restore insulin receptor sensitivity. It just turns down the tap. And when the body adapts — which it does — the numbers stop moving.
Week three on Metformin: fasting blood sugar stuck at 174. Post-meal spike still hitting 210. Brain fog every afternoon. Week four: 173. Couldn't eat without Tums. Plateauing already. Week five: 171. Doctor says "we're seeing progress." You feel worse.
- Metformin suppresses symptoms — it doesn't fix the root cause
- GI side effects affect up to 30% of users within the first month
- Plateaus are common because the mechanism doesn't address insulin receptor function
- Brain fog and fatigue are frequently reported but rarely discussed at appointments
The problem isn't that you're not trying hard enough. The problem is the tool you're using was never designed to fix what's actually broken.
You're Getting "Progress" on Paper — But Feeling Worse Every Day
There's a particular kind of frustration that comes with being told your numbers are improving while your body is telling you something completely different. Stomach cramping that starts in week two. Nausea that makes eating feel like a gamble. A bottle of Tums that becomes a permanent fixture on the nightstand.
These aren't minor inconveniences. They're signals. When a medication is causing this level of GI distress, your body is working against it — not with it. The active compounds are irritating your gut lining instead of supporting your metabolism. And the brain fog that settles in every afternoon? That's not just tiredness. That's your glucose regulation still misfiring despite the medication.
The question nobody asks at the six-week check-in is: are you actually feeling better? Because a six-point A1C improvement that comes with daily stomach pain and afternoon brain fog isn't progress. It's a trade-off.
There's a version of blood sugar support that doesn't ask you to choose between your numbers and your quality of life.
Ceylon Cinnamon + MCT Oil: The Absorption Difference That Changes Everything
Ceylon cinnamon has been studied for its effect on insulin receptor sensitivity — the mechanism that Metformin doesn't touch. The active compounds in true Ceylon cinnamon help cells respond more effectively to insulin, which means glucose gets processed rather than left circulating in the bloodstream.
But here's the part that most people — and most supplements — get wrong: the delivery method determines whether any of this actually works. Ceylon cinnamon compounds are fat-soluble. They need a lipid carrier to cross the gut lining and reach the bloodstream. Without one, the majority of the active compounds get trapped in fiber and pass through your system unused.
Resia solved this by concentrating authentic Ceylon cinnamon from Sri Lanka at a 12-to-1 ratio into a liquid extract, then infusing it with organic MCT oil inside easy-to-swallow softgels. When the softgel dissolves, the cinnamon extract is already suspended in oil — creating a bioavailable solution your body can absorb directly into the bloodstream. No harsh powder. No cinnamon burps. No wasted active compounds.
- 12-to-1 concentration delivers 7,200mg equivalent per softgel
- MCT oil acts as a lipid carrier — the same mechanism used in pharmaceutical-grade delivery systems
- Authentic Ceylon from Sri Lanka — virtually zero coumarin, safe for daily therapeutic use
- Softgel format dissolves completely — no powder residue, no GI irritation
One softgel delivers what dozens of regular cinnamon pills attempt to provide — but in a form your body can actually use.
The Cinnamon You've Tried Before Was Never Going to Work
Walk into any pharmacy or health food store and you'll find cinnamon supplements on the shelf. Most of them are Cassia cinnamon — the same cheap variety used in grocery store spice jars, sourced primarily from China. Cassia contains significant levels of coumarin, a compound that can stress the liver at therapeutic doses. It's not what was used in the research. It's not what works.
Even the supplements that do use Ceylon cinnamon typically stuff it into hard gelatin capsules as a dry powder. Your stomach has to break down both the capsule and the fibrous powder before any active compounds can be absorbed — and by the time that process is complete, most of what you swallowed has already passed through. You're not getting the dose on the label. You're getting a fraction of it.
- Most store brands use Cassia cinnamon — not the Ceylon studied for blood sugar support
- Hard capsule powder format has poor bioavailability — active compounds pass through unused
- Cassia contains liver-stressing coumarin — unsafe at daily therapeutic doses
- True Ceylon from Sri Lanka has virtually no coumarin — safe for long-term daily use
If cinnamon hasn't worked for you before, the problem almost certainly wasn't the cinnamon.

Six Weeks. The Same Person. Three Times the Results.
The numbers tell the story more clearly than any claim could. Both tracked over the same six-week window. Same starting A1C of 8.9. Same person. The only variable was what was being taken.
On Metformin: fasting blood sugar went from 182 to a plateau of 169. A1C moved from 8.9 to 8.3 — a six-point improvement. Stomach cramping started in week two. Post-meal spikes still hitting 210 in week three. Brain fog every afternoon. By week five, the doctor said "we're seeing progress" while the patient felt worse.
On Resia Ceylon Cinnamon: week two, fasting down to 161 — no side effects, sleeping better. Week three, down to 148 — energy stable, fog cleared. Week five: 128. First time under 130 in two years. Week six: fasting 121. A1C from 8.9 to 7.1 — an 18-point improvement in the same six weeks.
- Week 1–2: More stable energy, fewer afternoon crashes, reduced sugar cravings
- Week 3–4: More balanced throughout the day, less energy roller coaster
- Week 6–8: Most significant improvements in overall well-being and metabolic support
- Zero GI side effects reported — no cramping, no nausea, no Tums required
Same timeline. Three times faster. No side effects. The numbers don't require interpretation.
When Your Doctor Asks "What Brand?" — That's When You Know
There's a moment that happens at the six-week follow-up that changes the conversation entirely. The doctor pulls both sets of results side by side — the Metformin numbers and the Ceylon cinnamon numbers — and goes quiet for a moment.
Then: "Metformin moved you six points in six weeks with side effects. This moved you 18 points with none. What brand are you using?"
That question — from a physician who has spent years prescribing the standard protocol — is the most honest endorsement a natural supplement can receive. Not a testimonial. Not a marketing claim. A doctor, looking at the data, asking what's in the bag.
The answer was Resia. Ceylon cinnamon extract and MCT oil. 7,200mg equivalent per softgel. Sourced from Sri Lanka. Concentrated 12-to-1. Infused in organic MCT oil for maximum bioavailability. Made in an FDA-registered facility. And backed by a 90-day guarantee — because the company is confident enough in the results to let you test it yourself before you commit to anything.

What Customers Are Saying After 6–8 Weeks
"I was skeptical after trying three other cinnamon supplements that did nothing. My neighbor told me this one was different because it's concentrated and in oil form instead of powder. After 8 weeks, my doctor noticed my numbers were more stable and asked what I'd changed. I told him about the Ceylon cinnamon and he said whatever I'm doing, keep it up. No stomach issues like the other brands gave me either."
"For years my blood sugar was all over the place and every reading stressed me out. I felt like no matter how clean I ate or how hard I tried, my numbers never stayed consistent. Since starting Resia, everything feels steadier and those afternoon crashes don't control me anymore. My energy lasts through the day and I'm not constantly reaching for caffeine or sugar. For the first time in a long time, I feel like I'm back in charge of my health."
"Even my doctor commented on how much steadier my blood sugar has been since I started using Resia. Within weeks, my readings became more predictable and I stopped stressing over constant spikes and crashes. For the first time in years, I finally feel in control of my glucose levels. I used to start every morning dreading what the meter would say. Now I actually look forward to checking."

This is exactly what happened to me. I was on Metformin for 8 months and my doctor kept saying "give it more time." I finally asked about alternatives and he basically said there weren't any that were proven. Started Resia two months ago and my last A1C was the lowest it's been in four years. I'm not saying stop your medication — talk to your doctor — but I wish I'd known about this sooner.
Same experience here. The GI issues from Metformin were the worst part for me. Switched to this and within two weeks the cramping was completely gone. Numbers are better too.
The MCT oil delivery thing is real. I'm a nurse and I've been recommending fat-soluble supplements in oil form to patients for years because of the absorption difference. The fact that someone finally put this together with Ceylon cinnamon specifically is great. The coumarin issue with Cassia is a real concern for daily use that most people don't know about.
Thank you for explaining this! I had no idea there was a difference between Cassia and Ceylon. I've been taking the wrong kind for two years wondering why nothing was happening.
I was skeptical about the 90-day guarantee but it's real. I tried it for 10 weeks, didn't see the results I wanted (I think my situation is more complex), emailed them, and had a full refund within 3 days. No hassle at all. That alone tells you they believe in the product. I might try it again after adjusting my diet.
