Daily Ceylon Cinnamon: Safe Amounts, Realistic Doses, and When to Stop
Abstract Summary
Objective
To synthesize adult dosing evidence and safety data in order to provide goal-matched daily guidance for Ceylon cinnamon.
Context
Trials have tested doses of one to six grams daily for outcomes like glycemia and lipids, sometimes specifying Ceylon species. Three grams has been directly studied for gastric emptying effects.
Methods Used
Approach
Reference doses were identified for everyday wellness, digestive support, and short-term trial-style supplementation.
Data Collection
One to two grams daily is a conservative range consistent with antioxidant-focused studies. Around three grams with a meal has evidence for gastric emptying support. Higher intakes up to six grams have precedent in short-term trials, though safety monitoring and species verification are essential.
Researchers' Summary of Findings
Impact on Health
Correctly dosed Ceylon may modestly support post-prandial comfort and antioxidant status. Excessive intake or non-Ceylon products raise safety risks due to coumarin.
Health Implications
Begin at the lower end of the range, increase cautiously, and consult a clinician if you have liver disease or take medications with hepatic or anticoagulant effects.
Sustainability
Suppliers should disclose species, origin, and coumarin content to reduce variability and increase product safety.
