Ceylon Cinnamon in Black Sugar Protect: What the Research Shows
The brand graphic lists "Concentrated Ceylon Cinnamon" but gives no amount. In trials, people with type 2 diabetes took 120 mg to 6 g of cinnamon a day; fasting glucose fell by about 24.6 mg/dL, while HbA1c did not change. Ceylon is the low-coumarin type. Check the amount on the bottle you receive.

On the label
How much Ceylon cinnamon is in Black Sugar Protect?
Nobody outside the company can say, because the amount is not disclosed. The brand's ingredient graphic shows the words "Concentrated Ceylon Cinnamon" as the third of six names, with no milligram figure and no extract ratio (Black Sugar Protect sales page).
"Concentrated" usually means an extract made from a larger weight of bark. The brand does not say how strong it is, so even a milligram figure would leave one question open: concentrated from how much bark?
A paid, brand-supplied press release also lists Ceylon cinnamon and says the amounts are not publicly disclosed (Newswire, sponsored).
| Label name | "Concentrated Ceylon Cinnamon" (brand graphic) |
|---|---|
| What it is | Cinnamomum verum bark, called true cinnamon |
| Type | Spice extract |
| Position on the label | 3 of 6 on the brand's ingredient graphic |
| Amount per serving | amount not disclosed |
| What research shows | Trials used 120 mg to 6 g a day; fasting glucose fell, HbA1c did not change |
| Strength of evidence | Mixed; NCCIH calls the benefit unclear |
| Why it is in the formula (brand view) | The classic blood sugar spice |
| Main caution | Ceylon is low in coumarin, unlike cassia. Larger amounts are considered unsafe in pregnancy. |
The spice
What is Ceylon cinnamon, and how is it different from cassia?
Ceylon cinnamon comes from the bark of Cinnamomum verum, often called true cinnamon. It grows mainly in Sri Lanka. Cassia is a different species and the most common cinnamon sold in North America (NCCIH, Cinnamon).
The difference that matters most for safety is coumarin, a natural compound linked to liver effects in sensitive people. Cassia carries a lot of it. Ceylon carries only low levels (BfR, Coumarin FAQ).
| Point | Ceylon cinnamon | Cassia cinnamon |
|---|---|---|
| Species | Cinnamomum verum ("true cinnamon") | Several Cinnamomum species |
| Coumarin content | Low levels, a trace in some samples | About 3,000 mg per kg on average |
| Named by Black Sugar Protect? | Yes, "Concentrated Ceylon Cinnamon" | No |
| Amount in Black Sugar Protect | Not published | Not listed |
Evidence
Does cinnamon help blood sugar in studies?
The results are mixed. One well-known review pooled 10 randomized trials with 543 people with type 2 diabetes. Cinnamon lowered fasting glucose by about 24.6 mg/dL compared with controls, but HbA1c did not change in a meaningful way (Allen et al. 2013).
That gap matters. Fasting glucose is one morning snapshot, while HbA1c reflects the last few months.
- Doses varied widely: 120 mg to 6 g a day.
- Trials were short: 4 to 18 weeks.
- Results were uneven: the authors found high variation between trials and possible publication bias.
NCCIH says the diabetes benefit is unclear, partly because studies often skip the species (NCCIH, Cinnamon). The ADA's 2026 Standards go further: herb and spice supplements are not recommended for blood sugar benefit (ADA, Standards of Care 2026). How cinnamon ranks next to the other five ingredients is on the ingredients overview.
Dose check
What cinnamon dose did research use, compared with Black Sugar Protect?
Research amounts for all six ingredients, next to the product's undisclosed amounts.
- Berberine250-500 mg two or three times daily (usual herbal dose) (LiverTox, Berberine)?Black Sugar Protect: not disclosed
- Alpha-lipoic acid600 mg or more a day in oral trials, with no clinically meaningful benefit (AFP 2016, ALA neuropathy)?Black Sugar Protect: not disclosed
- Ceylon cinnamon120 mg to 6 g a day in trials (Allen et al. 2013)?Black Sugar Protect: not disclosed
- Magnesium350 mg a day: the upper limit for supplements, a ceiling, not a target (NIH ODS, Magnesium)?Black Sugar Protect: not disclosed
- Chromium25-35 mcg a day: what adults need, mostly from food (NIH ODS, Chromium)?Black Sugar Protect: not disclosed
- Licorice rootNo blood sugar dose studied; glycyrrhizin harms are dose related (MSK, Licorice)No blood sugar dose studied?Black Sugar Protect: not disclosed
Research amounts are reference points from NIH, LiverTox and trial reviews, not proof that any dose works. A 1 fl oz bottle sold as a 30-day supply leaves about 1 mL a day if both figures are right; whether that can hold gram-level berberine or cinnamon doses is an open question until the label is published.
The cinnamon bar spans 120 mg to 6 g a day (Allen et al. 2013). NCCIH notes that under 6 grams a day does not appear to pose a health risk (NCCIH, Diabetes and supplements). These are research figures, not the product's amount.
Every photo shows a 1 fl oz (30 mL) bottle, and the sales page calls one bottle a 30-day supply. If both are right, that leaves about 1 mL a day for all six ingredients. How could that hold a gram-level cinnamon dose? The sales text also says "capsule," so only your bottle's label can settle it.
Safety
Is Ceylon cinnamon safe, and what about coumarin?
Ceylon cinnamon is the safer choice on coumarin, and the brand deserves credit for naming it. Cassia averages about 3,000 mg of coumarin per kg, while Ceylon has only low levels (BfR, Coumarin FAQ).
Low coumarin
The tolerable daily intake for coumarin is 0.1 mg per kg of body weight, about 6 mg a day for a 60 kg adult. Ceylon makes that limit easier to respect (BfR, Coumarin FAQ).
Sensitive people
In a few sensitive people, medicinal coumarin doses caused usually reversible liver damage (BfR, Coumarin FAQ). Liver disease is a reason to ask first (NCCIH, Cinnamon).
Larger amounts
Larger amounts of Ceylon cinnamon during pregnancy are considered unsafe (NCCIH, Cinnamon). The product's amount is unknown, so ask before use if you are pregnant.
The cautions for all six ingredients are on the side effects page.
The bottle
Where would the cinnamon amount appear on a Black Sugar Protect bottle?
On the back, in a Supplement Facts panel, with the serving size. If the cinnamon sits inside a proprietary blend, the rules still require the blend's total weight on the same line (FDA, Labeling guide).
No photo of the back label has been published. When your bottle arrives, look for these three things next to the cinnamon line:
- A milligram figure, or a blend total that includes it.
- The species: Ceylon, Cinnamomum verum, or just "cinnamon."
- An extract ratio such as 10:1, if the word "concentrated" appears.
Our full checklist is on the label check page.
With medicines
Can you take cinnamon with diabetes medicines?
Ask your clinician first. The ADA warns that some supplement ingredients can add to diabetes medicines and cause low blood sugar (ADA, Vitamins and supplements). Cinnamon here sits beside berberine, alpha-lipoic acid and chromium, which carry their own cautions; see the berberine profile.
A reading below 70 mg/dL with shakiness, sweating or confusion needs treatment right away (NIDDK, Hypoglycemia). Keep taking your medicines as prescribed.

FAQ
Ceylon cinnamon in Black Sugar Protect: common questions
Does Black Sugar Protect use Ceylon or cassia cinnamon?
The brand's ingredient graphic names "Concentrated Ceylon Cinnamon," the type low in coumarin. No species name, extract ratio or amount is published, so check the cinnamon line on the bottle you receive to confirm what is inside.
How many milligrams of cinnamon are in Black Sugar Protect?
The amount is not disclosed anywhere we could open. For reference only, trials in people with type 2 diabetes used 120 mg to 6 g of cinnamon a day. Compare that range with the label on your bottle once it arrives.
Does cinnamon lower A1C?
Not in the pooled trial data. A review of 10 trials found fasting glucose about 24.6 mg/dL lower with cinnamon, but HbA1c did not change significantly. NCCIH calls any diabetes benefit unclear, and the ADA does not recommend spice supplements for blood sugar.
Is Ceylon cinnamon safe for the liver?
Ceylon cinnamon contains only low levels of coumarin, the compound tied to liver effects, while cassia averages about 3,000 mg per kg. Coumarin's tolerable daily intake is 0.1 mg per kg of body weight. People with liver disease should still ask their clinician first.
Can I take Ceylon cinnamon while pregnant?
Larger amounts of Ceylon cinnamon during pregnancy are considered unsafe, according to NCCIH. Because the amount in Black Sugar Protect is not published, and berberine in the same formula should be avoided in pregnancy, talk to your clinician before using it.
Is cinnamon in a supplement better than cinnamon in food?
There is no clear proof either way. Trials tested supplements from 120 mg to 6 g a day, often without naming the species. A supplement may hold a concentrated extract, so the amount and type printed on the label matter more than the word cinnamon.
