The evidence is difficult to interpret

NCCIH notes that cinnamon studies vary in species and plant part, making results difficult to compare. It says it remains unclear whether cinnamon supplementation is helpful for diabetes or weight loss.

Cassia vs Ceylon

Different cinnamon species are not interchangeable. BloodArmor's merchant page currently identifies its ingredient as cassia cinnamon.

Safety context

Cinnamon in normal food amounts is generally different from concentrated supplement use. Supplement dose, duration and coumarin exposure can matter depending on the product.
