The “True Cinnamon” From Sri Lanka: Why Your Grocery-Store Cinnamon Never Touched Your Blood Sugar — and What People Over 50 Are Switching To
If your doctor said “let’s watch it” about your fasting glucose or A1C, read this short article before you buy another bottle of cinnamon.
All it takes is one ingredient — the right one. Real Ceylon cinnamon from Sri Lanka, concentrated and packed into one softgel. No proprietary blend. No mystery dose.
Americans over 50… listen up: there’s a reason the cinnamon capsules from the grocery store never moved your numbers.
Most of the “cinnamon” sold in America isn’t true cinnamon at all. It’s Cassia — the cheap cousin, loaded with a compound your liver doesn’t love.
Real Ceylon cinnamon is different. And it’s why more and more people who were told to “watch” their blood sugar are switching to Metabella Ceylon Cinnamon.
Here’s exactly why:
1Your Numbers Change After 50 — Even If Your Diet Doesn’t
More than 115 million American adults have prediabetes. 8 in 10 don’t know it. And after 65, it’s more than half of all adults, according to the CDC.
It usually shows up quietly: a fasting glucose that’s “a little high,” an A1C that’s “borderline,” a doctor who says “let’s watch it.” Underneath is often insulin resistance — your cells slowly stop responding to insulin the way they used to.
- Supports healthy blood sugar levels†
- Supports a healthy insulin response†
- Helps keep blood sugar steadier after meals†
- Supports steady, all-day energy†
- Real Ceylon with only traces of coumarin
One softgel a day. One ingredient. Nothing hidden.
2Most “Cinnamon” in America Isn’t Real Cinnamon
Walk down any spice aisle and you’ll see “cinnamon.” What you won’t see is which kind.
According to the National Institutes of Health, Cassia is the most common type of cinnamon sold in the United States and Canada. It’s harder, darker, cheaper — and it’s what ends up in most budget capsules.
True cinnamon — Cinnamomum verum — grows in Sri Lanka. Its bark is thin, delicate and rolled in many fine layers. It costs more to grow and harvest. That’s why you rarely see it.
3The Hidden Problem in Cheap Cinnamon Pills: Coumarin
Cassia contains coumarin — a natural compound that, in larger amounts, can strain the liver in sensitive people. The NIH notes that Cassia “might cause or worsen liver disease.”
Germany’s Federal Institute for Risk Assessment found that Cassia averages around 3,000 mg of coumarin per kilogram — and that just 2 grams of Cassia a day can already reach the tolerable daily limit for a 132-lb adult. Capsules made from Cassia powder can exceed it.
When researchers tested cinnamon supplements bought in US stores, every single one contained coumarin. Ceylon cinnamon? Only traces.
4What the Research Actually Shows
Cinnamon isn’t folklore. It’s one of the most researched botanicals for blood sugar.
A meta-analysis of 16 randomized controlled trials found cinnamon significantly lowered fasting blood sugar and improved insulin resistance (HOMA-IR) in people with prediabetes and type 2 diabetes.† In people with type 2 diabetes, an earlier analysis of 10 trials found fasting glucose dropped by 24.6 mg/dL on average.†
And the newest trial used Ceylon specifically: 210 adults (average age 58) took a Ceylon cinnamon extract for four months — fasting glucose, A1C and insulin resistance all improved from where they started.†
Here’s the catch: many older studies used Cassia — or didn’t even say which cinnamon they used. Which is exactly why the kind of cinnamon you take matters.
5Why Metabella Uses Only Real Ceylon — 12:1, With the Dose on the Label
Metabella Ceylon Cinnamon contains one ingredient: true Ceylon cinnamon (Cinnamomum verum) from Sri Lanka.
It’s concentrated 12:1 — so every softgel delivers the equivalent of 7,200 mg of raw cinnamon bark — suspended in MCT oil, third-party lab tested, Non-GMO and gluten-free.
No proprietary blend. No “mystery mechanism.” Just the real thing, printed on the label.
6One Softgel a Day — Easy Enough to Actually Stick With
Spoonfuls of powder in your coffee. Three capsules a day. That cinnamon aftertaste. It’s why most people quit by week two.
Metabella is one easy-to-swallow softgel a day, with breakfast or your largest meal. No taste, no powder, no routine to remember.
That matters more than you’d think: in clinical studies, cinnamon was taken daily for 4 to 18 weeks. Consistency is everything.†

Research on cinnamon is promising but mixed. Results vary between studies, many trials used Cassia or did not name the species, and findings from one extract cannot automatically be applied to another product.

Questions Readers Ask
What’s the difference between Ceylon and Cassia cinnamon?
Ceylon (Cinnamomum verum) is “true cinnamon” from Sri Lanka: thin, layered bark with only traces of coumarin. Cassia is the cheaper, harder bark sold in most stores — it averages around 3,000 mg of coumarin per kilogram, according to Germany’s Federal Institute for Risk Assessment.
Can I take it with metformin or other blood sugar medication?
Cinnamon may add to the effect of blood sugar medication. If you take any prescription medication — especially for blood sugar — talk to your doctor before you start, and keep monitoring as usual.
When will I notice a difference?
Blood sugar changes take time. In clinical studies, cinnamon was taken daily for 4 to 18 weeks — so we recommend giving Metabella at least 8–12 weeks of daily use.
