Can cinnamon (dalchini) help control blood sugar? Explore its potential benefits for diabetes, Ayurvedic uses, scientific evidence and safety precautions.
Cinnamon, commonly known as dalchini in India, is a popular kitchen spice that has attracted scientific interest for its potential role in blood sugar management. Traditionally used in various systems of medicine, including Ayurveda, cinnamon contains bioactive compounds that researchers are studying for their possible effects on glucose metabolism and insulin sensitivity. However, evidence remains mixed, and cinnamon should not be considered a replacement for prescribed diabetes treatment. <a href=”https://www.nccih.nih.gov/health/cinnamon/“>(Source: NCCIH)</a>
How Can Cinnamon Help Manage Blood Sugar?
Cinnamon contains compounds such as cinnamaldehyde and other polyphenols that may influence processes involved in glucose metabolism. Researchers have investigated whether these compounds can help the body respond to insulin more effectively and improve the movement of glucose from the bloodstream into cells.
1. May Support Insulin Sensitivity
Insulin is a hormone that helps glucose enter the body’s cells, where it can be used for energy. In people with type 2 diabetes, the body may become less responsive to insulin, a condition known as insulin resistance.
Laboratory studies suggest that certain cinnamon compounds may influence insulin signalling and glucose uptake. Some clinical studies have also reported improvements in measures of insulin resistance, although the results are not consistent across all trials.
2. May Help Lower Fasting Blood Glucose
Some clinical trials and systematic reviews have found that cinnamon supplementation may reduce fasting blood glucose levels in people with type 2 diabetes or prediabetes.
A 2024 systematic review and dose-response meta-analysis, published in Phytotherapy Research, examined 24 randomised controlled trials and reported improvements in fasting blood glucose, insulin resistance and HbA1c in participants taking cinnamon supplements.
However, studies differ in the type of cinnamon used, dosage, duration and quality. Other reviews have found insufficient evidence to establish cinnamon as an effective diabetes treatment. More high-quality research is needed to determine whether its effects are clinically meaningful and sustained over time.
3. May Influence Carbohydrate Metabolism
Preliminary laboratory research suggests that cinnamon compounds may affect enzymes involved in carbohydrate digestion and glucose metabolism. These findings have prompted further investigation into whether cinnamon could help moderate post-meal blood glucose responses.
Nevertheless, laboratory findings do not automatically translate into proven benefits in humans. More clinical evidence is needed before cinnamon can be recommended as a reliable way to control blood sugar.
What Does Ayurveda Say About Dalchini?
Ayurveda has a long tradition of using spices and plant-based ingredients as part of dietary and wellness practices. Dalchini, derived from the bark of Cinnamomum species, is valued for its aromatic properties and traditional use in food and herbal preparations.
In Ayurvedic practice, the management of Prameha—a group of conditions described in classical Ayurvedic literature that includes disorders associated with excessive urination and is often discussed in relation to diabetes—emphasises a broader approach to diet, physical activity, lifestyle and individual assessment.
Dalchini is used in traditional dietary and herbal practices, but it would be inaccurate to claim that classical Ayurveda establishes cinnamon alone as a proven cure for diabetes. Its specific role should be understood in the context of the particular Ayurvedic text or formulation being discussed, as well as modern clinical evidence.
Ayurvedic Approach to Diabetes Management
Traditional Ayurvedic approaches generally emphasise a balanced diet, regular physical activity and lifestyle practices tailored to the individual. These principles can complement modern diabetes care when they are safe and coordinated with a qualified healthcare professional.
People with diabetes should not discontinue insulin, oral medicines or other prescribed treatment in favour of cinnamon or any other herbal remedy.
How Can Dalchini Be Included in the Diet?
For most people, cinnamon can be used as a culinary spice in ordinary food quantities. It may be added to unsweetened tea, porridge or selected dishes for flavour.
There is no universally established cinnamon dose for treating diabetes, and drinking cinnamon water or taking cinnamon powder has not been proven to control the condition reliably. Supplements may contain concentrated amounts that differ considerably from normal culinary use.
People considering regular, high-dose cinnamon supplements should first consult their healthcare professional, particularly if they take diabetes medication or have liver disease.
Is Cinnamon Safe for People With Diabetes?
Cinnamon is generally considered safe in the quantities commonly used in food. However, consuming large amounts over long periods may cause adverse effects.
Cassia cinnamon, a widely available variety, can contain significant amounts of coumarin, a naturally occurring compound that may harm the liver in susceptible people when consumed in excessive amounts. Ceylon cinnamon generally contains much lower levels of coumarin.
People with liver disease should be particularly cautious about concentrated cinnamon products. Cinnamon supplements may also interact with medicines, and anyone taking glucose-lowering medication should discuss their use with a healthcare professional.
