NervoMax Cinnamon Extract: Which Type Is It, and How Much Could the Blend Hold?
NervoMax cinnamon extract is listed second in the 600 mg blend, with no amount and no type. The label does not say cassia or Ceylon. Cassia carries coumarin, which can strain the liver in large amounts. Whether cinnamon helps blood sugar is unclear, and no study shows it helps nerves.

Plain words
What kind of cinnamon is in NervoMax cinnamon extract?
NervoMax cinnamon extract is two words on a label, and almost nothing else is printed.
The line reads Cinnamon Extract, second in the Test Boost Proprietary Blend. There is no species name, no extract ratio and no amount. That gap matters because the two common types of cinnamon differ in one key way: how much coumarin they carry. Coumarin is a natural flavor compound that can strain the liver when intake is high.
Cassia is the type most U.S. grocery stores sell. Ceylon is often called true cinnamon and is sold in specialty shops. Cassia holds far more coumarin. The NervoMax label does not say which one it uses, so the coumarin in the blend cannot be worked out from the label.
The math
How much cinnamon extract could NervoMax hold?
The amount is not printed, so we can only set a ceiling. Cinnamon extract is second of nine, and blend ingredients run from most to least by weight. Only pink salt comes before it. So the extract can be no more than half of the 600 mg blend. That is at most 300 mg per 2 capsules. An even split of nine gives about 67 mg.
The coumarin limit gives a yardstick. Germany's risk agency set a tolerable daily intake of 0.1 mg of coumarin per kg of body weight. For a 60 kg adult, about 2 g of cassia cinnamon a day can reach that level. The 300 mg ceiling is about 15 percent of that 2 g figure.
- On its own, that dose is unlikely to reach the limit if the cinnamon is plain cassia.
- An extract may be more concentrated, and the label gives no ratio.
- Cinnamon from food, teas or other supplements adds up with it.
Blood sugar
Does NervoMax cinnamon extract 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. Some trials saw small changes, while others saw none. Studies also used many types, doses and lengths, which makes them hard to compare, and none tested NervoMax.
The NervoMax label itself makes no blood sugar claim. Its claims are about nerve function and occasional numbness and tingling. Steady blood sugar control is what protects nerves over time, and that comes from your treatment plan, not from a spice. Cinnamon is not a replacement for diabetes care.
If you take diabetes medicine or metformin, ask your doctor before adding NervoMax. The site lists both among the cases that need a question first.
Safety
Who should be careful with NervoMax cinnamon extract?
Coumarin is mainly a concern for people with liver disease. If you have a liver condition, ask the maker which cinnamon it uses before you start. The blend also holds green tea extract, which has been linked to rare liver injury, so the liver question is wider than cinnamon alone.
Pregnant or nursing readers, people under 18 and anyone living with a medical condition should ask a physician first. That caution is printed on the label. Read more in our post on NervoMax safety and on the cinnamon ingredient page.
Your check
How can you check NervoMax cinnamon extract for yourself?
Four steps, about ten minutes, with the bottle and your medicine list.
- List your medicines. Write down diabetes medicine, metformin, blood thinners, acid reducers and heart medicine.
- Count your cinnamon. Note cinnamon supplements, teas and heavy use in food. These add to the blend.
- Ask the maker. Call the order desk at +1 (302) 200-3480 and ask which cinnamon species is used, the extract ratio and the amount per serving. Ask for the answer in writing.
- Show your doctor. Bring the list and the bottle. If a question has no answer, treat it as unknown.
If you notice yellow skin or eyes, dark urine, pain in the upper right belly, nausea or unusual tiredness, stop and call your doctor.

Our view
Our view
Our view: the cinnamon line is a good example of a label that says little. No type, no ratio and no amount mean the coumarin question has no answer on the bottle.
Ask the maker, write down the reply and show your doctor, especially if you take diabetes medicine or have liver disease. Do not rely on a spice for blood sugar control.
