Meta description: I take Ceylon cinnamon alongside my other blood sugar habits. Here’s what the research actually says, and what I’ve noticed since.

I take Ceylon cinnamon most mornings, and it’s become one of those small daily habits I don’t think twice about anymore. So, I want to dig into what the research says about it, because “I take it and I feel like it helps” isn’t the same as “here’s proof it works,” and I want to be straight with you about the difference.

Ceylon vs. Cassia — the distinction actually matters

If you’ve ever grabbed a jar of cinnamon at the grocery store, there’s a good chance it’s Cassia cinnamon, not Ceylon. They’re not the same plant, and the difference isn’t just semantics.

Cassia contains a compound called coumarin at much higher levels than Ceylon does. In large amounts over time, coumarin can be hard on the liver — it’s really an issue with higher or prolonged intake, not something that makes ordinary Cassia cinnamon in your kitchen dangerous. Ceylon cinnamon — sometimes labeled “true cinnamon” — has much less coumarin, though it’s not completely free of it either. That’s a big part of why I choose it for daily use rather than whatever’s in my spice cabinet.

What the research actually shows

Here’s where I want to be careful, because supplement marketing loves to round up. The honest answer is that the evidence on cinnamon and blood sugar is mixed.

Some studies have found real effects. One small clinical trial, published in BMC Complementary and Alternative Medicine in 2014, found a Ceylon cinnamon extract reduced post-meal glucose levels during the first hour after eating in healthy adults, compared to a placebo. But a separate study in the British Journal of Nutrition looked at people with impaired glucose tolerance and found Ceylon cinnamon made no real difference to their post-meal glucose or insulin. Animal research, including a 2014 study in PLoS ONE, has pointed to cinnamon extract possibly improving insulin sensitivity, though that’s in mice, not people. And a broader meta-analysis in Diabetes Research and Clinical Practice, which pooled results across many studies, found some improvement in fasting glucose and insulin resistance overall, but also a lot of variation between individual studies — bodies, doses, and study designs vary so much that it’s hard to draw one clean conclusion.

So, what does that mean in plain terms? Cinnamon isn’t a magic fix, and it’s not doing the heavy lifting on its own. It’s a small piece that might help at the margins for some people, alongside the things that actually move the needle — how you eat, how you move, and if you’re using something like a glucose monitor, how you use that feedback.

Why I take it in softgel form

I use Elorita Ceylon Cinnamon Softgels — they’re made with MCT oil, gluten-free, and it’s an easy way to get a consistent amount of Ceylon cinnamon every day without measuring out powder. I started out taking a plain Ceylon cinnamon capsule with no MCT oil in it, and it worked fine. At some point I switched to one with MCT oil instead, mostly because it felt like an easier, more convenient format for me. Around that same time, I noticed my spikes weren’t as significant and my numbers felt steadier. I can’t say for certain the switch is what did that versus everything else I’ve got going on, but it’s the one thing I know changed right around when I noticed the difference.

I take mine with breakfast and don’t think about it again until the next morning.

Where cinnamon fits into my bigger picture

I want to be honest about something: my blood sugar numbers have improved since I started paying attention to all of this — the glucose monitor, the Glucose Insiders Academy program, my eating habits, and yes, the cinnamon too. I can’t tell you how much of that improvement is the cinnamon specifically, because I changed a lot of things at once. What I can tell you is that it’s a habit I keep because it fits easily into my routine and I haven’t had a reason to stop.

If you’re curious about how a glucose monitor fits into that picture, I walk through my first 30 days with mine here.

A couple things to know before you try it

Cinnamon can interact with certain medications, including blood thinners and medications used to manage blood sugar or diabetes, so talk to your doctor before you add it in. Pregnant or breastfeeding? Same advice — check first. And if you notice any digestive upset, stop and pay attention to that too.

My takeaway

Ceylon cinnamon isn’t going to replace the fundamentals, and I’m not going to pretend the science is more settled than it is. But it’s a habit that fits easily into my routine, and it’s one I’ve kept around. If you want to try it yourself, this is the one I use — the coumarin difference between Ceylon and Cassia is worth knowing about, but how much it matters really depends on the type and amount of cinnamon you’re already getting, so it’s worth thinking about in the context of your own diet.

Are you already taking cinnamon, or thinking about adding it in? I’d love to hear what’s worked for you — drop it in the comments.
