Cinnamon Bark Concentrate

Also known as: Cinnamon, Ceylon cinnamon, Cassia cinnamon, Cinnamomum cassia, Cinnamomum verum

Overview

Cinnamon is a spice derived from the bark of trees from the genus *Cinnamomum*. The two main types are Ceylon cinnamon (*Cinnamomum verum*) and Cassia cinnamon (*Cinnamomum cassia*). It is widely used in cooking and as a dietary supplement due to its flavor, aroma, and potential health benefits. Cinnamon contains compounds like cinnamaldehyde, responsible for its distinctive characteristics and bioactive properties. Research on cinnamon is extensive, with studies examining its effects on blood sugar control, inflammation, and lipid metabolism. The quality of evidence varies, with some high-quality systematic reviews and meta-analyses available, alongside studies with methodological limitations. Cinnamon is available in various forms, including whole sticks, ground powder, extracts, and capsules.

Benefits

Cinnamon has demonstrated potential benefits, particularly for individuals with Type 2 Diabetes. Meta-analyses have shown a statistically significant decrease in mean HbA1c by 0.09% (95% CI: 0.04-0.14) and fasting plasma glucose by 0.84 mmol/L (95% CI: 0.66-1.02). Some studies suggest that cinnamon may also reduce total cholesterol, LDL-C, and triglycerides while increasing HDL-C. These benefits are most pronounced in individuals with Type 2 Diabetes, with effects typically observed within short-term studies (less than 4 months). While the effect sizes are generally small, they are statistically significant, suggesting potential clinical utility in managing diabetes as an adjunct therapy.

How it works

Cinnamon's mechanism of action appears to involve mimicking insulin's effects, increasing glucose uptake in adipocytes and skeletal muscles. It interacts with metabolic pathways, influencing glucose and lipid metabolism. Cinnamaldehyde, a major component of cinnamon, is believed to be responsible for its bioactive effects. The bioavailability of cinnamon's active compounds can vary based on the form and preparation. Further research is needed to fully elucidate all mechanisms of action and optimize its use.

Side effects

Cinnamon is generally considered safe when consumed in typical dietary amounts. However, high doses, particularly of Cassia cinnamon, may cause adverse effects due to its coumarin content. Common side effects are rare at standard doses, but some individuals may experience allergic reactions or gastrointestinal upset. High doses may lead to liver damage due to coumarin toxicity. Cinnamon may interact with diabetes medications, potentially enhancing their effects, so monitoring blood sugar levels is crucial. High doses should be avoided in individuals with liver issues or those taking anticoagulants due to coumarin content. Pregnant women and individuals with diabetes should consult healthcare providers before using cinnamon supplements.

Dosage

For glycemic control, a typical minimum effective dose is around 1-2 grams per day. Studies often use doses between 1-6 grams per day. Doses above 6 grams per day are generally not recommended due to potential coumarin toxicity, especially with Cassia cinnamon. Ceylon cinnamon is preferred due to its lower coumarin content. It is best taken with meals to minimize gastrointestinal upset. Bioavailability may vary based on preparation and individual factors. There are no specifically identified required cofactors.

FAQs

Can cinnamon replace my diabetes medication?

No, cinnamon is not a replacement for standard diabetes treatment but may be used as an adjunct. Monitor blood sugar levels closely, especially if taking diabetes medications concurrently.

What type of cinnamon is best to use?

Ceylon cinnamon is preferred over Cassia cinnamon due to its lower coumarin content, reducing the risk of liver damage with regular use.

When is the best time to take cinnamon?

Cinnamon is best taken with meals to reduce the potential for gastrointestinal side effects. Consistent timing can also help in assessing its effects on blood sugar.

How long does it take to see results from taking cinnamon?

Improvements in blood sugar control may be observed within a few weeks of consistent use. However, individual responses can vary, and it should be used as part of a comprehensive diabetes management plan.

Are there any safety concerns with taking cinnamon?

High doses of Cassia cinnamon should be avoided due to its coumarin content, which can be toxic to the liver. Consult with a healthcare provider before starting cinnamon supplementation, especially if you have liver issues or are taking other medications.
