Cinnamon Extract in NervoMax: Type, Coumarin and Blood Sugar
NervoMax lists cinnamon extract second in its 600 mg blend, with no amount and no type. The label does not say cassia or Ceylon. Cassia contains coumarin, which can strain the liver in large amounts (BfR, Coumarin). Whether cinnamon helps blood sugar is unclear (NCCIH, Cinnamon). No study shows it helps nerves. If you take diabetes medicine, ask your doctor first.

The basics
What kind of cinnamon is in NervoMax?
The label does not say. It reads only "Cinnamon Extract," second in the "Test Boost Proprietary Blend." There is no species name, no extract ratio and no amount.
That gap matters. The two common types of cinnamon differ in one key way: how much coumarin they carry (BfR, Coumarin).
| Label name | Cinnamon Extract |
|---|---|
| What it is | Cinnamomum species (type not stated) · Bark extract |
| Position on the label | 2 of 9 (labels list blend ingredients from most to least by weight) |
| Amount on the label | Undisclosed share of the 600 mg blend |
| What research has used | Blood-sugar studies are unclear; cassia coumarin limit 0.1 mg per kg |
| Strength of evidence | Weak |
| What it is sold for | Sold for blood sugar; no nerve evidence |
| Main caution | Cassia cinnamon carries coumarin; caution with liver disease or diabetes medicine. |
Two types
Cassia vs Ceylon cinnamon: what is the difference?
Cassia is the type most U.S. grocery stores sell. Ceylon is often called "true cinnamon." Cassia holds far more coumarin, a natural flavor compound (BfR, Coumarin).
| Point | Cassia | Ceylon | NervoMax label |
|---|---|---|---|
| Coumarin | Can be high | Very low | Not published |
| Where you find it | Most grocery cinnamon | Specialty shops | Type not stated |
| Liver caution | Yes, at high intake | Low concern | Depends on type |
| Amount per serving | Varies by product | Not published | |
An extract adds another unknown, because the label gives no extract ratio. Without the type and ratio, the coumarin in NervoMax cannot be worked out from the label.
Safety
How much coumarin is too much?
Germany's risk agency set a tolerable daily intake of 0.1 mg of coumarin per kg of body weight (BfR, Coumarin). For a 60 kg adult, about 2 g of cassia cinnamon a day can reach that level.
Where NervoMax fits
Cinnamon is listed second, after salt. That means it cannot be more than half of the 600 mg blend, so at most 300 mg per 2 capsules. That ceiling is about 15 percent of the 2 g cassia figure.
- On its own, that dose is unlikely to reach the coumarin limit if the cinnamon is plain cassia.
- An extract may be more concentrated, and the label gives no ratio.
- Daily cinnamon from food, teas or other supplements adds up with it.
Coumarin is mainly a concern for people with liver disease (NCCIH, Cinnamon). If you have a liver condition, ask the maker which cinnamon they use before you start.
Evidence
Does cinnamon lower blood sugar?
The research is unclear. The National Center for Complementary and Integrative Health says it is not clear whether cinnamon helps people with diabetes (NCCIH, Cinnamon). Some trials saw small changes, while others saw none.
Studies also used many different types, doses and lengths. That makes them hard to compare, and none tested NervoMax. The label itself makes no blood sugar claim. Its claims are about nerve function and occasional numbness and tingling.
Cinnamon is not a replacement for diabetes care. Steady blood sugar control is what protects nerves over time, and that comes from your treatment plan, not a spice.
Before you start
How do you check cinnamon safety for yourself?
Four steps, about ten minutes, with the bottle and your medicine list.
- 01
Check the label type
Read the Supplement Facts line. It says only Cinnamon Extract, with no species and no amount.
- 02
Count your other cinnamon
Add up cinnamon capsules, teas and daily baking spice. Cassia is the common grocery type.
- 03
Ask about your medicines
Diabetes medicine and liver conditions are the two to raise with your doctor or pharmacist.
- 04
Track how you feel
Note your blood sugar readings and any stomach upset in the first weeks. Bring the notes to your visit.
Medicines
Can you take NervoMax cinnamon with diabetes medicine?
Ask your doctor or pharmacist first. Many people buying a nerve supplement have diabetes, and cinnamon is sold for blood sugar. If it did lower blood sugar, it could add to what your medicine already does.
Picture a 62-year-old with type 2 diabetes on metformin who also takes cinnamon capsules from the drugstore. Adding NervoMax stacks a second, unmeasured cinnamon dose on top. Bring both bottles to the appointment.
Talk to your doctor before adding cinnamon supplements if you take diabetes medicine or have liver disease (NCCIH, Cinnamon). Watch for low blood sugar signs such as shakiness or sweating, and report them.
Metformin can also lower vitamin B12 over time, which is a separate point covered on the vitamin B12 page.
Nerve claims
Does cinnamon help nerve tingling?
No study shows that cinnamon helps nerve function, numbness or tingling. It is best known for flavor and blood sugar research, not nerves. The label does not explain why it is in the blend.
FDA does not review supplements for safety or effect before they reach shelves (FDA, Using supplements). The FTC expects health claims to rest on competent and reliable science (FTC, Health claims). For cinnamon and nerves, that science has not been published.
Bottom line
Is cinnamon a useful part of NervoMax?
It is a familiar spice with a small safety question and no nerve evidence.

- Amount capped at 300 mg by label order

FAQ
Cinnamon in NervoMax: FAQ
Is the cinnamon in NervoMax cassia or Ceylon?
The label does not say whether NervoMax uses cassia or Ceylon cinnamon. It lists only Cinnamon Extract, with no species and no amount. Call the order desk at +1 (302) 200-3480 and ask the maker for the type if coumarin is a concern for you.
How much cinnamon is in NervoMax?
No cinnamon amount is printed. Cinnamon is second in the 600 mg blend, after salt, so it can be at most 300 mg per 2 capsules. The real amount may be much lower. Ask the maker for the exact figure.
Is coumarin in cinnamon supplements dangerous?
Coumarin is a concern mainly in large amounts or with liver disease. The tolerable intake is 0.1 mg per kg of body weight a day (BfR, Coumarin). About 2 g of cassia a day can reach that for a 60 kg adult.
Can cinnamon pills lower blood sugar?
It is unclear whether cinnamon pills lower blood sugar in a useful way. NCCIH says the evidence for diabetes is not clear (NCCIH, Cinnamon). Results differ across studies, types and doses. Do not use cinnamon in place of diabetes treatment.
Can I take NervoMax with metformin?
Ask your doctor first. NervoMax contains cinnamon, which is sold for blood sugar, so it may add to diabetes medicine. Metformin can also lower B12 levels. Bring the bottle to your visit so your doctor sees the full label.
Does cinnamon help neuropathy?
No study shows that cinnamon helps neuropathy, numbness or tingling. Cinnamon research has looked mostly at blood sugar, with unclear results (NCCIH, Cinnamon). Good blood sugar control through your treatment plan is what protects nerves in diabetes.
Is cinnamon safe for the liver?
Ceylon cinnamon carries little coumarin. Cassia carries more, and high coumarin intake can harm the liver (BfR, Coumarin). Because NervoMax does not name its cinnamon type, people with liver disease should ask their doctor before taking it.
