The Evidence-Based Health Benefits Of Cinnamon

The Evidence-Based Health Benefits Of Cinnamon

Cinnamon is one of the most popular consumed exotic spices worldwide and has a long history of traditional medicinal usage.

There are approximately 250 species within the Cinnamomum genus, of which Cinnamomum zeylanicum(True Cinnamon) and Cinnamon Cassia are the two main varieties.

Clinical research has found that Cinnamon exerts antioxidant, anti-inflammatory, antilipemic, antidiabetic, antihypertension, antimicrobial, gastroprotective and anticancer effects.

The main active constituents of cinnamon are cinnamaldehyde, eugenol, and trans-cinnamaldehyde (Cin), which contribute to the fragrance and to the various biological activities observed with cinnamon.

Cinnamon also contains water soluble polyphenol polymers including procyanidins and catechins, which are thought to be responsible for its insulin potentiating benefits.

Traditionally the bark of Cinnamon is used as a remedy for digestive ailments, respiratory disorders and gynaecological issues.

Cinnamon Improves Glycaemic Control

Cinnamon Glycaemic Control Systematic Review Meta-Analysis

Several studies have found that Cinnamon has an anti-diabetic effect and can improve metabolic health in Type 2 Diabetes Mellitus patients.

Cinnamon seems to be highly bioactive, appearing to mimic the effect of insulin through increased glucose uptake in adipocytes and skeletal muscles.

Polyphenolic polymers found in cinnamon may function as antioxidants, potentiate insulin action, and may be beneficial in the control of glucose intolerance and diabetes. [1]

A systematic review and meta-analysis published 2012 examined the effect of cinnamon on glycaemic control in patients with Type 2 Diabetes mellitus.

Six clinical trials met the strict inclusion criteria. Patients consumed between 1 to 6 grams of Cinnamon per day.

Meta-analysis of RCTs showed a significant decrease in mean HbA1c and mean FPG (Fasting Blood Glucose).

The systematic review and meta-analysis concluded:

Use of cinnamon showed a beneficial effect on glycaemic control (both HbA1c and FPG) and the short term (<4 months) effects of the use of cinnamon on glycaemic control looks promising. [2]

Another recent narrative review published 2018 concluded:

About 1-6 g of these cinnamon species mainly in powder seems to be an adjunct drug treatment for type 2 diabetes mellitus and other conditions of glycemic impairment [3]

Cinnamon Reduces Blood Pressure

Cinnamon Reduces Blood Pressure

Numerous studies have found that cinnamon can potentially significantly reduce systolic blood pressure (SBP) and diastolic blood pressure (DBP).

A systematic review and meta-analysis published in 2020 evaluated the overall effects of cinnamon supplementation on blood pressure in adults.

Meta-analysis of 9 RCTs with 641 participants showed significant reductions in both systolic (WMD: −5.17 mmHg, 95% CI: −9.35 to −0.99, P = 0.01) and diastolic blood pressure (WMD: −3.36 mmHg, 95% CI: −5.67 to −1.04, P ≤ 0.001) after cinnamon supplementation.

The systematic review and meta-analysis concluded:

The present meta-analysis suggests that cinnamon supplementation can improve blood pressure by a modest degree. [4]
