Quiet the Gut, Keep the Meal: Ceylon Cinnamon’s Role in Digestion
Abstract Summary
Objective
To map adult dosing from peer-reviewed trials to digestive goals such as gastric emptying, post-prandial comfort, and antimicrobial support, and relate dose ranges to typical food-use patterns.
Context
“Cinnamon” trials often pool species, but where species is identified, Ceylon shows effects on gastric emptying at modest culinary doses. In vitro and small clinical adjunct studies also explore anti–H. pylori potential, though eradication data remain preliminary.
Methods Used
Approach
Reference doses were identified by outcome, focusing on gastric emptying and antimicrobial support.
Data Collection
Three grams of Ceylon cinnamon taken with a meal has been shown to affect gastric emptying and post-prandial glucose handling. Other studies using one to six grams of mixed cinnamon species similarly reduced post-meal glucose, though species were often unspecified. In vitro work suggests antimicrobial potential, but clinical dose validation is lacking.
Researchers' Summary of Findings
Impact on Health
For post-meal comfort and glycemic steadiness, three grams of Ceylon cinnamon with a meal is a practical, trial-anchored starting point.
Health Implications
Ceylon cinnamon, with its low coumarin content, allows safe daily use well below the EFSA threshold of 0.1 mg/kg/day. Coordination with a clinician is advised for individuals with gastrointestinal disease or those taking anticoagulants or hepatotoxic medications.
Sustainability
Sourcing should emphasize clear species labeling (C. verum), origin disclosure, and batch testing, especially for coumarin content.
