The evidence in words
The verdict
For fasting glucose, Cinnamon earns evidence grade C (small effect, mixed consistency) — the evidence is limited or mixed. Inconsistent
How it might work
Cinnamon polyphenols may improve insulin sensitivity and slow gastric emptying, modestly affecting post-meal glucose.
How to use it
1–2 g/day; prefer Ceylon cinnamon for regular supplemental use to limit coumarin.
Safety & cautions
High-dose cassia coumarin can stress the liver; additive glucose lowering with diabetes drugs.
Bottom line
A mild, unreliable glucose nudge. If you use it daily, choose Ceylon over cassia to avoid the coumarin liver risk.
How it is used
As the entry records it, from the studies it summarises. Not a recommendation for you — doses that suit a trial population may not suit you.
