Ceylon Cinnamon
Reviewed by the Nimbera editorial team · Last updated May 2026
How to use
Take 1-2 g of Ceylon cinnamon daily in capsule form, or add 1 teaspoon of Ceylon cinnamon powder to food or a warm drink. Consume with or just before a carbohydrate-containing meal for best blood sugar effect. Use consistently for at least 8-12 weeks.
How it works
Cinnamon's polyphenols mimic insulin signaling by activating insulin receptors and glucose transporters. It also slows gastric emptying to blunt post-meal glucose spikes, inhibits pancreatic alpha-amylase to reduce carbohydrate digestion, and reduces triglyceride synthesis in the liver.
Where to buy
Grocery stores, health food stores, Amazon - look for 'Ceylon cinnamon' or 'true cinnamon' (Cinnamomum verum), not Cassia cinnamon
Typical cost: $10-$20 per month
Safety notes
IMPORTANT: Use Ceylon cinnamon only, not Cassia (the common grocery store variety). Cassia contains high coumarin levels which can cause liver damage at supplemental doses. Do not exceed 2 g/day. May lower blood sugar - monitor closely if on diabetes medications. Avoid medicinal doses during pregnancy.
