Cinnamon Bark In GlycoAid
A cupboard spice with a longer trial history than anything else on this list.

Where It Comes From
Inner bark from trees in the Cinnamomum family, dried into the quills sold as cinnamon sticks. Identical to what sits in a kitchen cupboard.
What the research is about
The rise in glucose that follows a meal, mainly. It holds the longest unbroken run of human research of any culinary spice in this category, and the results across that run are genuinely mixed.
Two species, one label word
Cassia is the supermarket type and contains coumarin; Ceylon holds far less. A panel declaring only Cinnamomum bark does not distinguish between them, and this one does not.
Evidence grade: Large. A substantial body of controlled human research stands behind this ingredient, almost always at quantities a 500 mg fourteen-name blend cannot reach.
Fast Facts
| Deepest file for | Post-meal glucose response |
|---|---|
| Usual study quantity | 1–6 g daily |
| Quantity here | Undisclosed, inside the 500 mg total |
| Species | Cassia or Ceylon; the panel does not say |
| Watch item | Coumarin in cassia at sustained high intakes |
The Quantity Question
Protocols run from one gram to six grams daily. That is a gram-scale figure set against a 500 mg total shared fourteen ways, which places the cinnamon here a long way below any study quantity.
Cautions
Cassia carries coumarin, a liver concern when intake is kept high over long periods. At the scale a 500 mg blend permits this is not a practical worry, but it is why cinnamon supplements measured in grams deserve a second look.
Questions About Cinnamon Bark
Same as kitchen cinnamon?
Identical bark. The panel names Cinnamomum bark without specifying the species.
Does cinnamon lower blood sugar?
It has been studied for post-meal response with mixed results across many trials, and nothing about it treats a diagnosed condition.
Could I eat cinnamon instead?
Study quantities are gram-scale, beyond what a capsule holds. The same arithmetic says the amount here is very small.
Is coumarin an issue in this product?
Not at this scale. The concern belongs to gram-level daily cassia intake sustained over long periods.
How It Sits In The Blend
Cinnamon Bark is printed inside one 500 mg proprietary formulation alongside thirteen other names, so the quantity here is unknown. That is the position on every panel page on this site, and 500 mg, divided works through what that arithmetic permits. The name above it on the panel is Berberine and the one below is Gymnema Sylvestre.
