CinnamonHealth is an independent, evidence-based research site for Australians interested in the health properties of cinnamon. Every article is written against peer-reviewed clinical literature — no supplement sponsorships, no affiliate revenue, no hype.
The site exists because cinnamon is one of the most researched botanical supplements for metabolic health — but most online information is either dangerously oversimplified or outright misleading. Our goal is to give you the real picture, clearly explained.

Before reading anything else — start with these four foundational concepts.
Most cinnamon sold in Australia is Cassia — not Ceylon. This distinction matters enormously for daily supplementation because of coumarin content and liver safety.
Read: Ceylon vs Cassia →EFSA guidelines cap daily coumarin at 0.1mg/kg bodyweight. For a 70kg adult using Cassia, that's around ½ teaspoon per day max. Ceylon has no such limit.
Read: Safe Dosage Guide →At therapeutic doses, cinnamon has real pharmacological activity. It interacts with diabetes medications, blood thinners, and blood pressure drugs.
Read: Drug Interactions →The strongest evidence is for blood sugar regulation in Type 2 diabetes — backed by 25+ RCTs. Evidence for PCOS, cholesterol, and inflammation is growing.

What type of cinnamon should I buy?
Ceylon cinnamon (Cinnamomum verum) is recommended for daily use. It has negligible coumarin levels, unlike Cassia which dominates supermarket shelves in Australia.
How strong is the evidence for blood sugar benefits?
Strong. Over 25 randomised controlled trials and multiple meta-analyses support modest but statistically significant improvements in fasting blood glucose and HbA1c in Type 2 diabetes.
What dose is considered safe?
For Ceylon: 1–3g/day is well-tolerated. For Cassia: EFSA recommends no more than 0.1mg coumarin per kg bodyweight per day — roughly 0.5–1g for most adults.
Can cinnamon replace diabetes medication?
No. Cinnamon may complement medical treatment but should never replace prescribed medications. Always consult your GP or endocrinologist before making changes to your treatment plan.
