What is Cinnamon Extract?

Cinnamon Extract is a concentrated preparation from the bark of Cinnamomum species. It contains compounds such as polyphenols and cinnamaldehyde.

What are the potential benefits of Cinnamon Extract?

It is studied for supporting healthy blood sugar levels, antioxidant defenses, and cardiometabolic markers like cholesterol and triglycerides. Effects can vary by product type, dose, and individual health status.

What is a typical dosage for Cinnamon Extract?

Common supplemental amounts are often in the range of 120–500 mg per day, depending on the extract and its standardization. Follow the product label and consult a clinician if you have diabetes or take medications.

Are there side effects or safety concerns with Cinnamon Extract?

Some people may experience digestive upset or allergic reactions. Products high in coumarin (often associated with Cassia cinnamon) may be a concern with high intake, especially for people with liver issues.

Does Cinnamon Extract interact with medications?

It may add to the blood-sugar-lowering effects of diabetes medications and could increase the risk of hypoglycemia. Discuss use with a healthcare professional if you take glucose-lowering drugs, anticoagulants, or have liver disease.

dose range

120–500 mg

divided with meals

Consumption

Take in divided doses with meals to improve bioavailability and minimize potential gastrointestinal effects.

Not fat-soluble.

Best time

Taking with meals is preferred for optimal absorption; avoid exceeding recommended dosage, and monitor for adverse effects, particularly if using cassia cinnamon extract due to coumarin content.

Description

Cinnamon extract is derived from the bark of Cinnamomum species and is rich in polyphenols and cinnamaldehyde. Traditionally used as a spice and herbal remedy, it has recently gained popularity for its effects on glucose regulation, cholesterol, and oxidative stress in clinical settings.

Safety & Information

Important safety information & known risks

For educational purposes only • not medical advice

Cinnamon extract is generally safe within recommended doses, but high intake (especially of cassia types) or use with certain medications can cause adverse effects.

warning notices

Allergic reactions (rash, mouth sores) are possible in sensitive individuals.
Cassia cinnamon extracts are high in coumarin, which can cause liver toxicity at excessive doses.
Risk of hypoglycemia when combined with antidiabetic drugs.
Potential for increased bleeding when used with anticoagulants.
Avoid use during pregnancy due to insufficient safety data.
Do not use if you have liver disease or are taking hepatotoxic medications due to risk of liver toxicity, especially with cassia cinnamon extracts.
Use only under medical supervision if taking antidiabetic or blood-thinning medications, as additive effects may cause hypoglycemia or increased bleeding risk.
Discontinue use if allergic reactions or mouth sores occur.

Known interactions with medications

antidiabetic medications
anticoagulants
hepatotoxic medications

Contraindications / special precautions

pregnancy
liver disease
known allergy to cinnamon

interactions

Important interactions between active ingredient ↔ supplement / medication / food

Cinnamon extract may interact with blood sugar-lowering drugs, anticoagulants, and hepatotoxic medications, requiring caution in at-risk populations.

Cinnamon may enhance glucose-lowering effect of antidiabetic drugs

drug · antidiabetic medications

MonitorModerate

Why

Cinnamon can independently reduce blood glucose; additive effect may lead to hypoglycemia when used with oral hypoglycemics or insulin.

recommendation

Monitor blood sugar closely and adjust medication dose as needed, under medical supervision.

S1 · PubMed (Khan A et al., 2013)S2 · NIH NCCIH Cinnamon Fact Sheet S9 · Cochrane Review: Cinnamon for diabetes mellitus

Cinnamon may increase bleeding risk with blood thinners

drug · anticoagulant medications (including warfarin)

CautionLimited

Why

Cinnamon extract may have mild blood-thinning properties and could potentiate the effects of anticoagulant drugs.

recommendation

Consult a healthcare provider before combining; monitor for bleeding signs.

S2 · NIH NCCIH Cinnamon Fact Sheet

Risk of liver toxicity when combined with hepatotoxic drugs

drug · hepatotoxic medications

AvoidModerate

Why

Cassia cinnamon contains coumarin that is hepatotoxic at high doses; combined use elevates risk.

recommendation

Avoid combination if possible, especially in those with liver disease.

mechanisms of action

Brief explanations of how it works

Modulation of insulin signaling

Cinnamaldehyde and polyphenols in cinnamon may enhance insulin receptor activity and GLUT4 translocation, resulting in improved cellular glucose uptake.
